Use of Ester-Bridged Side Chains to Suppress Caloric Availability of Fat Compounds

This invention relates to the use of inter- and intra-molecular ester bridges of the formula

where n=1 to 8, between fatty side chains attached to fat compounds of natural and synthetic origin. These ester bridges suppress caloric availability and modulate the functional characteristics of the fat mimetics.

Dietary fat is the most concentrated source of energy of all the nutrients, supplying 9 kcal/gram, about double that contributed by either carbohydrate or protein. The amount of fat in the American diet has increased in the last 60 years by about 25% (Mead, J., et al. Lipids, Plenum, New York, 1986, page 459), so that fats now provide approximately 40% (or more) of the daily caloric intake. Moreover, technological advances in the food industry, including efficient and safe hydrogenation procedures, have changed the kind of fat in foods.

Because fats are high in calories and because some fats appear to pose a health risk when consumed in large quantities over time, a number of national advisory committees on nutrition have made recommendations differing in detail, but the common theme is a reduction in the total amount of fat in the diet (Gottenbos, J. J., chapter 8 in Beare-Rogers, J., ed., Dietary Fat Requirements in Health and Development, A.O.C.S. 1988, page 109 . Yet fat contributes to the palatability and flavor of food, since most food flavors are fat-soluble, and to the satiety value, since fatty foods remain in the stomach for longer periods of time than do foods containing protein and carbohydrate. Furthermore, fat is a carrier of the fat-soluble vitamins, A, D, E, and K, and the essential fatty acids, which have been shown to be important in growth and in the maintenance of many body functions. Hence, major research efforts have focused on ways to produce food substances that provide the same functional and organoleptic properties as fats, but not the calories.

A number of fat replacements have heretofore been suggested (recently reviewed by Hamm, D. J., 49 J. Food Sci. 419-428 (1984), Haumann, B. J., 63 J. Amer. Oil Chem. Soc. 278-288 (1986) and LaBarge, R. G., 42 Food Tech. 8414 90 (1988)). Hamm divides replacement fats into two broad categories: structurally re-engineered triglycerides modified to retain their conventional functional properties in foods, while removing their susceptibility toward hydrolysis or subsequent absorption during digestion, and materials developed from chemistry unrelated to triglycerides.

Examples of the former class of triglyceride analogues include compounds having the glycerol moiety replaced with alternate polyols (e.g., pentaerythritol in U.S. Pat. No. 2,962,419 to Minich, or sugars, suggested by Hess, K., and Messmer, E., 54B Ber. 499-523 (1921), and patented years later by Mattson and Volpenhein, U.S. Pat. No. 3,600,186, and Meyer, et al., U.S. Pat. No. 4,840,815); compounds having the fatty acids replaced with alternate acids (e.g., branched esters as described in U.S. Pat. No. 3,579,548 to Whyte); compounds having insertions between the glycerol and the fatty acid (e.g., ethoxy or propoxy groups in U.S. Pat. No. 4,861,613 to White and Pollard); compounds having reversed esters (e.g., malonates in U.S. Pat. No. 4,482,927 to Fulcher and trialkoxytricarballylates in U.S. Pat. No. 4,508,746 to Hamm); and compounds having the ester bonds replaced by ether bonds (Can. Pat. No. 1,106,681 to Trost).

Related to triglyceride analogues are dimeric glycerides. Thirty years ago, the U.S.D.A. assessed the caloric availability and digestibility of a series of new-type fats, including dibasic acid-bridged diglycerides (specifically, fumaric, succinic and adipic-bridged diglyceride esters; see Feuge, R. O., and Ward, T. L., 80 J. Amer. Chem. Soc. 6338-6341 (1958); Ward, T. L., et al. 36 J. Amer. Oil Chem. Soc. 667-671 (1959); Feuge, R. O., and Ward, T. L., 37 J. Amer. Oil Chem. Soc. 291-294 (1960); and Shull, R. L., et al. 38 J. Amer. Oil Chem. Soc. 84-86 (1961)). Minich suggested ether-bridged dipentaerythritol esters about the same time (U.S. Pat. No. 2,962,419, column 53 to 76), although he exemplified only monomeric pentaerythritol esters.

Examples of Hamm's second category of fat replacements chemically unrelated to triglycerides are mineral oil (suggested as early as 1894 in U.S. Pat. No. 519,980 to Winter); polyglucose and polymaltose (U.S. Pat. No. 3,876,794 to Rennhard); jojoba wax (W. Ger. Pat. No. 3,529,564 to Anika); polyoxyalkylene esters (U.S. Pat. No. 4,849,242 to Kershner); polyvinyl alcohol esters (U.S. Pat. No. 4,915,974 to D'Amelia and Jacklin) and polysiloxane (Eur. Pat. Ap. Pub. No. 205,273 to Frye).

Nondigestible or nonabsorbable edible fat replacements have proved disappointing when tested in feeding trials, where gastrointestinal side effects occurred, in some cases so extreme that frank anal leakage was observed. Nondigestible fats appear to act as a laxative and are expelled from the body, eliciting foreign body reactions like those early documented for mineral oil (Stryker, W. A., 31 Arch. Path. 670-692 (1941), more recently summarized in Goodman and Gilman's Pharmacological Basis of Therapeutics, 7th ed., Macmillan Pub. Co., N.Y. 1985, pp. 1002-1003). Similarly, experimental fats synthesized by the U.S.D.A group mentioned above exhibited undesirable gastrointestinal side effects when the compounds were fed to rats (Booth, A. N., and Gros, A. T., 40 J. Amer. Oil Chem. Soc. 551-553 (1963)); in several of the balance studies, the diarrhea was so extreme that digestibility coefficients could not be calculated ibid., Table I, p. 552).

Polyglycerol and polyglycerol esters, suggested as fat replacements by Babayan and Lehman (U.S. Pat. No. 3,637,774), have been suggested for use as fecal softening agents as well (U.S. Pat. No. 3,495,010 to Fossel). A number of remedies have been recommended to combat the anal leakage observed when sucrose polyesters are ingested (e.g., employing cocoa butters, U.S. Pat. No. 4,005,195 to Jandacek, incorporating saturated fatty groups, Eur. Pat. Ap. No. 233,856 to Bernhardt, or mixing residues, U.S. Pat. No. 4,797,300 to Jandacek, et al.). Saturated fatty acids have been suggested as anti-anal leakage agents for polyorganosiloxane fat replacements (U.S. Pat. No. 4,925,692 to Ryan), and dietary fiber preparations have been incorporated into foodstuffs containing other fat replacements to help inhibit the diarrheal effect (U.S. Pat. No. 4,304,768 to Staub et al.). Partially digestible fat replacements have also been suggested (U.S. pat. Nos. 4,830,787 and 4,927,659 to Klemann and Finley).

An object of the present invention is to provide a new approach to the design of fat mimetic compounds, and to provide new groups of fat mimetic compounds structurally related to those heretofore suggested. More particularly, it is an object of the present invention to suggest a way of altering the side chains of fat mimetic compounds and triglycerides, to modulate functional characteristics and caloric availability while minimizing laxative side effects.

These and other objects are accomplished by the present invention, which describes the use of inter- and intra-molecular ester bridges of the formula

where n=1 to 8, between fatty side chains attached to fat compounds. These ester bridges, generally formed by the condensation of fatty side chains bearing hydroxyl groups with dibasic acids or dibasic acid derivatives, can be used with both fat mimetics and triglycerides. Ester-bridging of side chains modulates caloric availability and alter the chemical and physical properties of the compounds.

This invention describes a structural modification of previously disclosed edible fat compounds that simultaneously modulates both the caloric availability and functional characteristics of the compounds. This invention describes intra- and inter-molecular ester bridges of the formula

where n=1 to 8, between fatty side chains of fat compounds.

The compounds of this invention are monomers, dimers, and oligomers (of 3 to 8 subunits) comprising fat compounds having fatty side chains linked together with ester bridges. Any fat compounds comprising a backbone to which are attached fatty side chains (e.g., fatty acid or fatty alcohol residues) are suitable for this invention, including natural or synthetic edible fats heretofore suggested. Examples of fat compounds include, for example, triglycerides, mono- and di-glycerides, diol diesters, polyol polyesters (e.g., sucrose, glucose, and raffinose polyesters), esterified propoxylated or ethoxylated glycerol and the like, neoalkyl esters, polyglycerol esters, polyoxyalkylene esters, polyvinyl alcohol esters, carboxy/carboxylates, polycarboxylic and dicarboxylic acid esters, mono/diglycerides of short-chain dibasic acids, glyceryl ethers, plant sterol esters, jojoba esters, amino acid esters, amides, thio esters, and the like, and mixtures thereof. Neoalkyl esters include, but are not limited to, trishydroxymethyl alkane esters. Triglycerides include, but are not limited to, natural, synthetic and processed (e.g., transesterified, interesterified, partially hydrogenated and fully hydrogenated) triglycerides.

The structural modification of the present invention generally results in two types of side chains on the fat compounds: ester bridged side chains comprising the linkages described above and unbridged side chains comprising pendant fatty groups which have not been modified.

In the practice of the present invention, ester bridged side chains are formed by reacting dibasic carboxylic acids, or dibasic carboxylic acid derivatives, with hydroxyl functions situated on side chains of the fat compounds. By "side chains" are meant, in this context, the aliphatic portions of the fat compounds which contain points of attachment for the dibasic acid bridges such that the portions of the molecules between the points of attachment and the ends of the side chains comprise only carbons and hydrogens.

The hydroxyl groups on the side chains serving as the attachment points for the bridges may be natural constitutents of the side chains, as is the case with ricinoleic acid and ricinoleyl alcohol, glycolic acid, lactic acid, mixtures thereof and the like. Alternatively, fat compounds containing side chain hydroxyl moieties may be derived using common methods of transesterification or interesterification between fat compounds and hydroxycarboxylic acids or hydroxycarboxylic acid derivatives (e.g., methyl lactate and the like). Alternatively, hydroxyl groups may be added to double bonds on fat compound alcohol or acid residues, e.g., to oleyl, oleic, palmitoleyl, palmitoleic, nervonyl, nervonic, and the like, to form hydroxylated derivatives, or prepared from bromo or chloro derivatives by reaction with KOH (as summarized in U.S. Pat. No. 4,363,763 to Peterson, column 5, line 66 to column 6, line 30). Additionally, hydroxyl groups may be attached in the omega position by enzymatic catalysis or other methods known in the art.

Dibasic acids forming the ester bridges have the formula HO(CO)--(CH.sub.2).sub.n --(CO)OH, where n=1 to 8. Thus, the ester bridges may be derived from any dibasic acid in the oxalic acid series having 1 and as many as 8 (n) methylene groups, for example, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic, and sebacic acids. The bridges are formed by reacting either the dibasic acids, or dibasic acid derivatives (e.g., chlorides or anhydrides), with hydroxyl groups on the fatty side chains of fat compounds.

Attachment of the dibasic acids to the side chain hydroxyl groups result in intramolecular or intermolecular ester bridges. By "intramolecular" is meant pertaining to different parts of the same molecule, and applies to monomeric fat compounds having ester bridges between side chains. By "intermolecular" is meant pertaining to more than one molecule, and applies to dimeric or oligomeric fat derivatives having ester bridges between side chains on different fat compounds. As used herein, "oligomeric" means comprising 3 to 8 subunits. Thus, intermolecular ester bridges of this invention may join trimers, tetramers, pentamers, hexamers, heptamers and octamers.

The ratio of bridged side chains to unbridged side chains in the compounds is generally on the order of 25 to 70 mole per cent, more narrowly 25 to 50 mole per cent, even more narrowly 30 to 35 mole per cent. Thus, one embodiment of this invention comprises bridging one side chain of a fat compound having three side chains to another side chain of a fat compound having three side chains to yield an intermolecular bridge; in the bridged structure, two side chains are bridged and four are unbridged, yielding a molar ratio of 1 to 3 (or .about.33.3%). In another embodiment, one side chain of a fat compound having three side chains is bridged to another side chain of a fat compound having four side chains to yield an intermolecular bridge spanning two side chains and five unbridged side chains in the resulting structure, which corresponds to a molar ratio of bridged to unbridged side chains of 2 to 5 (or 40%). In yet another embodiment, one side chain of a fat compound having three side chains is bridged to another side chain of a fat compound having two side chains to yield an intermolecular bridge spanning two side chains and three unbridged side chains in the resulting structure, which corresponds to a molar ratio of bridged to unbridged side chains of 2 to 3 (or .about.66.7%).

Unbridged fatty side chains are generally of two major types. The first are fatty acid residues derived from natural or synthetic fatty acids of the formula RCOOH, where R is an aliphatic group having 1 to 30 carbons. R aliphatic groups may be linear or branched, saturated or unsaturated. Examples of fatty acids are acetic, propionic, butyric, caproic, caprylic, pelargonic, capric, undecanoic, lauric, myristic, palmitic, stearic, arachidic, behenic, erucic, brassidic, lignoceric, cerotic, montanic, melissic, palmitoleic, oleic, vaccenic, linoleic, linolenic, eleostearic, arachidonic, nervonic, eicosapentaenoic, docosatetraenoic, docosapentaenoic, docosahexaenoic, and the like acids.

Mixtures of fatty acids may also be used, such as those obtained from the hydrolysis of non-hydrogenated, partially hydrogenated or fully hydrogenated soybean, safflower, sunflower, sesame, peanut, corn, olive, rice bran, canola, babassu nut, coconut, palm, palm kernel, lupin, nasturtium seed, mustard seed, cottonseed, low erucic rapeseed, dairy butter or marine oils. Fatty acids derived from other fats, such as tallow or lard, or plant waxes such as jojoba may be employed. Specific fractions of natural or processed oils, fats or waxes may also be used.

The second type of unbridged fatty side chains include fatty alcohol residues derived from synthetic or natural fatty alcohols of the formula RCH.sub.2 OH, with R a linear or branched, saturated or unsaturated aliphatic group having 1 to 30 carbons. Examples of fatty alcohols include the counterparts to the fatty acids listed above, namely, ethyl, propyl, butyl, hexyl, caprylyl, pelargonyl, capryl, lauryl, undecanyl, myristyl, palmityl, stearyl, arachidyl, behenyl, erucyl, brassidyl, lignoceryl, cerotyl, montanyl, melissyl, palmitoleyl, oleyl, vaccenyl, linoleyl, linolenyl, eleostearyl, arachidyl, nervonyl, eicosapaentanyl, docosatetraenoyl, docosapentaenyl, or docosahexaenyl alcohols. Mixtures of fatty alcohols may also be employed, including those obtained from the processed or unprocessed natural oils, fats or waxes enumerated above, or specific fractions of the oils, fats or waxes.

The side chains and the bridges will be selected to provide a discernible fatty character in the compounds. Thus, most of the R groups have 2 to 4 or more carbon atoms with a percentage containing 4 to 24, more narrowly 10 to 20, and even more narrowly, 14 to 18 carbon atoms. Preferred bridged fat compounds can have an array of R groups selected to include 95% derived from saturated and unsaturated acids having 14 to 18 carbon atoms. In one embodiment, the R should be predominantly saturated and derived from C.sub.14 to C.sub.18 acids and alcohols. In another embodiment, the R should be predominantly derived from unsaturated C.sub.16 to C.sub.18 acids and alcohols (with a preponderance of monounsaturated groups).

The choice, number and arrangement of R groups on the side chain-linked derivatives and the backbones will affect the biological as well as physical properties of the compounds. Where, by virtue of any of these factors, fatty groups are metabolized, the caloric value of the compound will increase. Where an R group is metabolized, it may be a highly desirable or essential fatty acid such as linoleic acid.

Some compounds are partially digestible. By this is meant that the compounds deliver less than 9 kcal/gram, preferably less than 5, and, in some embodiments, less than 3 kcal/gram, upon being metabolized.

The fat compounds of this invention may be incorporated either alone, or in combination with another fat and/or fat mimetic, into any food composition comprising fat and nonfat ingredients, or used in conjunction with any edible material. Other fats include natural triglycerides rich in highly desirable or essential fatty acids, such as oleic, linoleic, linolenic, or eicosapentaenoic acid, triglycerides bearing fatty acids having beneficial attributes such as those associated with conjugated linoleic acid isomers, medium chain triglycerides and the like. Other fat mimetics include any heretofore suggested as edible fat replacements, including, but not limited to, sugar esters, neoalkyl esters, polyglycerol esters, malonate esters, propoxylated glycerols, retrofats, monomeric carboxy/carboxylates, and the like. The term "edible material" is broad and includes anything edible, whether or not intended for nutrition, e.g., it can be an additive such as an antioxidant for fats or oils, an anti-spatter agent, an emulsifier, a texture modifier such as a plasticizer for chewing gum, a component for cosmetics, or other minor functional ingredient such as a carrier or diluent for use in flavorings, pharmaceuticals, and the like.

Representative of fat-containing edible materials comprising food ingredients and fat mimetic compounds of this invention in full or partial replacement of the natural or synthetic fat are: frozen desserts, e.g., frozen novelties, sherbet, ice cream, ices, or milk shakes; puddings and pie fillings; margarine and margarine substitutes or blends; flavored bread or biscuit spreads; mayonnaises and mustards; salad dressings; filled dairy products such as filled cream or filled milk; dairy or non-dairy cheese spreads; coffee lighteners, liquid and dried; flavored dips; frying fats and oils; nut products such as peanut butter; reformed and comminuted meats; meat substitutes or extenders; pet foods; whipped toppings; compound coatings; frostings and fillings; cocoa butter replacements or blends; candy, especially fatty candies such as those containing peanut butter or chocolate; chewing gum; breakfast cereals; bakery products, e.g., cakes, breads, rolls, pastries, cookies, biscuits, and savory crackers; mixes or ingredient premixes for any of these; as well as flavor, nutrient, drug or functional additive delivery systems.

The following is a list of representative, but not limiting, examples of fat compounds having side chains which may be linked by the ester bridges of this invention: ##STR1## where the R groups are derived from corn oil ##STR2## where R is derived from safflower oil fatty acids ##STR3## where R is derived from corn oil fatty acids

The following examples are presented to further illustrate and explain the present invention and should not be taken as limiting in any regard. Unless otherwise indicated, all parts and percentages are by weight, and are based on the weight at the particular stage of the processing being described.

In this example, various adipate linked lactoyl-distearins, side chain ester-bridged compounds of this invention, are prepared in two steps. Adipate linked lactoyl-distearins are 2:1 adducts of lactoyl-distearin with adipoyl chloride, and comprise compounds of the formula ##STR4## compounds of the formula ##STR5## and compounds of the formula ##STR6##

Step 1. Interesterification of tristearin with methyl lactate. Tristearin (447 g, 0.5 mole) is melted in a 1000-mL flask fitted with a mechanical stirrer, reflux condenser, and a gas inlet and outlet. (S)-(-)-Methyl lactate (52 g, 0.5 mole) is added and mixed well, and then followed by 4.0 g of a 10% suspension of sodium methoxide in xylene. The mixture is placed under an atmosphere of dry nitrogen and is stirred for 24 hours at 60.degree. C. to complete an interesterification reaction. The reaction mixture is poured into 1000-mL hexane, and this solution is washed with 5% HCl, then water, and is dried over anhydrous sodium sulfate. Evaporation of the solvent and recrystallization of the product from acetone-hexane gives lactoyl-distearin as a mixture of 1,2- and 1,3-distearin isomers.

Step 2. 2:1 Adduct of lactoyl-distearin with adipoyl chloride. A sample of lactoyl-distearin prepared above (139.4 g, 0.2 mole) and 18.3 g (0.1 mole) adipoyl chloride are combined in a 500-mL flask fitted with a magnetic stirrer bar, a thermometer, and a distillation head connected to a vacuum source by means of a trap containing KOH pellets. The mixture is warmed to 70.degree. C., at which point evolution of HCl gas is observed. The temperature is then raised to 115.degree. C. for 7 hours, then the mixture is cooled and poured into 100 mL of 2% NaOH solution. The organic phase is isolated by centifugation, and the crude product is pressure filtered through a shallow bed of absorbent clay. Following vacuum steam deodorization, the 2:1 adduct, bis-(lactoyl-distearin) adipate, is obtained in 81% yield.

In this example, is-(2-lactoyl-1,3-dipalmitin) sebacate, a side chain ester-bridged compound of this invention described by the formula ##STR7## is prepared in two steps. Step 1. 2-Lactoyl-1,3-dipalmitin. The title compound is prepared following the procedures detailed by Goldblatt, L. A., et al., J. Amer. Chem. Soc. 77: 2477-2479 (1955).

Step 2. is-(2-lactoyl-1,3-dipalmitin) sebacate. 2-Lactoyl-1,3-dipalmitin (64 g, 0.1 mole) and 12 g (0.05 mole) sebacoyl chloride are combined in a 250-mL flask fitted with a thermometer, magnetic stirrer bar, and a distillation head connected to a vacuum source by means of a trap containing KOH pellets. The mixture is warmed to 115.degree. C. for 7 hours during which time HCl gas is evolved. The crude reaction mixture is allowed to cool and is dissolved in twice its volume of hexane. This solution is passed through a short, silica gel, flash chromatography column. The hexane eluate is concentrated in vacuuo, and the residue is steam deodorized to give the title product.

This example describes a three-step preparation of another side chain ester-bridged compound of this invention, bis-( 2,2-distearoyloxymethylbut-1-yl lactate) adipate, which may be described by the formula ##STR8##

Step 1. 2,2-Di-stearoyloxymethylbutan-1-ol. Stearic acid (284 g, 1.0 mole) and 67 g (0.5 mole) 2,2-di-hydroxymethylbutan-1-ol are combined in a 1000-mL flask fitted with a thermometer, vacuum distillation head, and mechanical stirrer. The mixture is heated at 150 Torr to 140.degree. C. for 16 hours and is then fractionally crystallized from hexane-ethanol to yield a fraction which is 95% of the title diester-alcohol (55% yield).

Step 2. 2,2-Distearoyloxymethylbut-1-yl lactate. The diester-alcohol prepared above (267 g, 0.4 mole) and 43.4 g of an 85% solution of lactic acid in water (0.4 mole lactic acid) are combined in a 1000-mL flask fitted with a thermometer, vacuum distillation head, and mechanical stirrer. The mixture is heated at 150 Torr to 140.degree. C. for 7 hours and is then fractionally crystallized from acetone-water to afford the title triester (93% compositionally pure) in 60% yield.

Step 3. Bis-(2,2-distearoyloxymethylbut-1-yl lactate) adipate. To a solution of 73.9 g (0.1 mole) of the triester prepared in Step 2 above in 200 mL dichloromethane and 20 mL pyridine is added dropwise a solution of 9.15 g (0.05 mole) adipoyl chloride in 50 mL dichloromethane. After the addition is complete, the reaction mixture is stirred at room temperature for 24 hours. The mixture is then poured into 500 mL dichloromethane. After the addition is complete, the reaction mixture is stirred at room temperature for 24 hours. The mixture is then poured into 500 mL of water and is extracted with diethyl ether. The organic phase is washed successivly with 5% HCl, 5% Na.sub.2 CO.sub.3 and water, and is dried over anhydrous sodium sulfate. After filtration, the solvent is removed under reduced pressure, and the residue is dissolved in hexane and passed through a short silica gel column (flash chromatography, hexane eluant). Evaporation of the hexane eluant and steam deodorization of the residue affords the title composition in 68% yield.

In this example, Bis-(2,2-distearoyloxymethylbut-1-yl) succinate, which may be described by the formula ##STR9## is prepared.

Bis-(2,2-distearoyloxymethylbut-1-yl lactate) succinate. To a solution of 73.9 g (0.1 mole) of the triester prepared in Step 2 of Example 3 above in 200 mL dichloromethane, and 20 mL pyridine, is added dropwise to a solution of 7.75 g (0.05 mole) succinyl chloride in 50 mL dichloromethane. After the addition is complete, the reaction mixture is stirred at room temperature for 16 hours. The mixture is then poured into 500 mL of water and is extracted with diethyl ether. The organic phase is washed successively with 5% HCl, 5% sodium carbonate, and water, and is dried over anhydrous sodium sulfate. After filtration, the solvent is removed under reduced pressure, and the residue is dissolved in hexane and passed through a short silica gel column (flash chromatography, hexane eluant). Evaporation of the hexane eluant and steam deodorization of the residue affords the title composition in 55% yield.
