Definitions

  • the general field of the present invention is new heat stable dipeptide salty tasting compounds which are capable of being substituted for sodium and potassium chloride seasoning agents in baking and cooking.
  • a process for salting, i.e., seasoning, comestibles with these new peptide salt substitutes is also described, as well as a novel food composition for making such process operable.
  • the particular new salty peptides are uniquely characterized in that they are heat stable and do not decompose when added to edible food compositions which are to be baked or cooked at or above or about 360°F before consumption.
  • DKP which is readily formed in all normally structured dipeptides formed by the union of two normally structured amino acids.
  • the object of the present invention is to describe and claim such a prouct and to illustrate to those skilled in the art of food chemistry how to employ such a new and unique composition of matter.
  • the present invention comprises a heat stable peptide salt composition which includes a peptide component composed of a plurality of amino acid residue components, at least one of which has been modified to include a cycloalkyl bridge in the structure and, in some cases, an edible hydrocolloidal gum.
  • the composition in its preferred product form comprises a soluble powder which is readily miscible with other food additives and food formulas.
  • cycloalkyl as employed in this specifica ⁇ tion is intended to refer to such cyclic functions as cyclo- propyl, cyclobutyl, cyclopentyl, cyclohexyl, and the like which are by means of their manner of preparation built into the particular amino acid concerned.
  • modified amino acids When these modified amino acids are noted herein, they will be distinguished in some cases by the symbol " ⁇ « prefixed to the name or abbreviation of the amino acid.
  • This added alkyl function has been found to act as a stabilizer of the peptide link between amino acids, at least one of which must exhibit the unique configuration.
  • the preferred peptide components are dipeptides of the normal or cycloalkyl substituted amino acids taurine .or ornithine coupled with such amino acids as cycloalkyl sub ⁇ stituted ornithine cycloalkyl substituted lysine or cycloalkyl substituted alanine.
  • These compounds and their mineral acid salts and lower alkyl esters exhibit unusual thermal stability, especially when complexed with a quantity of an edible hydro- colloidal gum such as gum acacia or gum tragacanth.
  • the hydrocolloidal gum is preferably a polysaccharide type hydrocolloidal gum, such as gum acacia, gum tragacanth, pectin gum, gum karaya, guar gum, larch gum, psyllium seed gum, or locust bean gum, for instance.
  • a polysaccharide type hydrocolloidal gum such as gum acacia, gum tragacanth, pectin gum, gum karaya, guar gum, larch gum, psyllium seed gum, or locust bean gum, for instance.
  • a major amount of the hydrocolloidal gum is complexed with a minor amount of the peptide after moistening the dry mix with a water to form a paste. If it is desired, one may dry by known means such as spray drying, drum drying, etc. the complex to form a powder for use in baking or cooking of foods in place of ordinary table salt, i.e., sodium chloride.
  • the new peptide containing table salt substitute comprises a soluble complex of:
  • R represents either hydrogen or a lower alkyl group of C-
  • n is a positive integer from 1 to 4, but preferably 1, and x can be either 1 or 2, depending on whether the cycloalkyl amino acid coupled to taurine is a cycloalkyl ornithine or a cycloalkyl lysine.
  • a thermally stabilizing amount of a hydrocol ⁇ loidal gum such as gum acacia or gum tragacanth.
  • the ratio of the amounts of the peptide and gum components in the complex will vary depending on the end use and the food composition being sweetened and the textural requirements of the end product. Generally, 5 to 10 parts of gum are used for each part by weight of peptide, but as much as 100 parts of the former to 1 part of the latter might be useful in some food applications. In still other uses, a minor amount of gum to the peptide could be considered. In the most preferred applications, a major amount of gum to a minor amount of peptide is needed to promote heat stability.
  • a second preferred product aspect of this invention is the peptide ingredients themselves such as the compounds of (1A), (2A), and (3A) hereinabove.
  • the R represents either hydrogen or a lower alkyl function' such as methyl, ethyl, propyl, or butyl, for instance, either normal or isomeric in configuration or benzyl
  • x is either 1 or 2
  • n is a positive integer from 1 to 4, and hence represents either cyclopropyl, cyclobutyl, cyclopentyl, or cyclohexyl functions.
  • a third preferred product aspect of the invention is a food composition which requires a salty material as one of its essential ingredients.
  • a cake mix formula for instance, where the peptide to gum ratio is critical to gain heat stabil ⁇ ity and concurrent satisfactory texture and other ingredient compatibility.
  • a new peanut butter formula or a pretzel or potato chip dough or pasta dough which can taste like sodium chloride laden dough but actually be salt free is contemplated.
  • One preferred process aspect of the present invention is the synthesis of a new salty tasting peptide by means of the following reaction: ornithine amino acid + cyclopropyl alanine > salty peptide
  • the known a in ⁇ acid ornithine is reacted under well known condensation conditions to form the unique peptide (3A). This is the first time this reaction will have been performed, and-the product obtained will be different than other dipeptides. It will be heat resistant and capable of being complexed with a gum to be heat stable, if desired.
  • a second preferred process aspect of the invention is the formulation of a new and unique cake mix which now becomes feasible for baking in the home.
  • sodium chloride is replaced with the new peptide III or (1A), (2A), or (3A) to obtain when baked a new cake which tastes like known cakes but varies in one material respect. It contains no sodium.
  • a final process aspect of the invention is the pre ⁇ paration of cooked meals and baked foods in the home without the use of sodium or potassium chloride table salts. In a similar manner, this process aspect applies to commercial preparation of prepared food products such as pastas, baked pies, cookies, pretzels, potato chips and corn chips, etc., of many different shapes and formulas.
  • hydrocolloidal poly.saccharide gums are known commercially available materials, the details of which are available in the Encyclopedia of Chemical Technology (3rd. Edition 1983) by Kirk-Othmer, Vol. 12, pages 57-67, published by John Wiley and Sons, New York, NY.
  • gum tragacanth is known to be a mixture of acidic polysac- charides containing galacturonic acid, galactose, fucose,' and xylose and arabinose. It is an exudate from the Astralagus tree found in Iran, Iran, and Turkey. Solutions are weakly acidic with a pH of 5.0 to 6.0, and a molecular weight range of 10,000 to about 250,000. Gum acacia, on the other hand, is a dried exudate obtained from the Acacia tree found chiefly in the African Sudan. It has a large molecular weight of a range of 200,000 to about 1,160,000, and is stable at a slightly acid to neutral range.
  • the alkaline hydrolysis of the hydantoin intermediate 3_ to the cyclopropylornithine amino acid reactant is achieved by suspending 6 grams of the hydantoin _3 from above in 100 mis. of 3 N sodium hydroxide and heating to reflux conditions and maintaining this reflux for 21 hours. At the end of this period, cool the reaction mixture and acidify to pH 6.0 with concentrated hydrochloric acid.
  • the cyclopropyl ornithine amino acid 4_ will precipitate from the solution in good yield. Filter the precipitate out and wash with cold water twice, then with acetone, and dry under high vacuo. Wash three more times with warm anhydrous ethanol to further purify. This product can then be recrystallized from a water/acetone mixture to obtain the cycloalkylamino ornithine amino acid _4 in high yield and excellent purity.
  • Step B Preparation of the Dipeptide of Cyclopropyl ⁇ ornithme and L-Taurine to Obtain a Salty Tasting Peptide 5
  • This peptide is synthesized by known and conventional methods using, however, a new and unique combination of reactive amino acids to yield a heretofore unknown peptide.
  • dibenzyloxycarbonyl ornithine and cyclopropyl alanine benzyl ester are condensed to yield a new corresponding dibenzyloxycarbonyl dipeptide benzyl ester by the mixed anhydride method.
  • This compound when deblocked, is a new peptide.
  • the protecting groups of the dipeptide derivatives are removed by catalytic hydrogenation in acetic acid solution.
  • the product is then treated HC1 -dioxane and obtained as .a hydrochloride salt.
  • the purity of the peptide can be confirmed by melting point, elemental analysis, optical rotation, and thin layer chromatography and NMR and HPLC.
  • Step 1 Preparation of Blocked Peptide as its Benzyl Ester Dissolve the dicyclohexylamine salt of L-ornithine (2.77 grams, 5 mmol) in 30 ml of ethyl acetate. Add 10 is. of 1 molar sulfuric acid to the mixture with constant stirring. Wash the organic layer with distilled water and dry over anhydrous sodium sulfate. Concentrate the solution to dryness in vacuo and dissolve the oily residue in 10 mis of tetra- hydrofuran and 0.55 mis of 5 mmol of N-methylmorpholine. Add 0.5 ml (5 mmol) of ethylchloroformate to this mixture at -5 ⁇ C and hold in this condition for 15 minutes.
  • Step 2 Hydrogenation to Deblock Ester
  • the blocked peptide from step 1 above (0.62 grams or 1.2 mmol) is dissolved in 5 is of acetic acid and hydrogenated in the presence of palladium black at room temperature for 3 hours. Remove the catalyst by filtration and evaporate the filtrate to dryness in vacuo.
  • This complex is the salty flavor ingredient employed as a replacement for sodium chloride in the following Example, which involves the preparation of a new baking formulation useful for baking of naturally tasting yellow cakes, for example, or other baked products. These food products will contain no sodium, yet will have all the attributes of food products prepared and baked using a formula which contains sodium chloride.
  • the sugar ingredient is replaced by the sweetener complex of Example II of the cited copending patent application.
  • the new improved cake formula hence is as follows:
  • Sweetener 208S (from U.S.S.N 680, ,345) 340.5
  • the above margarine is creamed, and the synthetic sweetener as a wet paste is added slowly over 10 minutes with constant stirring till light. The two eggs are then added. along with the vanilla flavor ingredient.. The mixture is then beaten at a moderate speed after each addition.
  • Example IV Repeat the procedure of Example IV, except to substitute 90 parts by weight of gum tragacanth (a water soluble hydrocolloidal polysaccharide gum) for the gum acacia employed in that example.
  • the complex will retain both its sweet and salty flavor during the bake cycle, and the cake obtained will be quite tasty and not able to be distinguished from cakes baked with addition of both sugar and sodium chloride.
  • the edible heat stable dipeptides of the present invention are particularly useful as salting and sweetening agents for baking pies and cakes, breads and other cooked or baked goods which must be heated to temperatures of the order of 350°F in the course of their preparation.
