Definitions

  • This invention is directed to a composition for calcium fortification of dairy products and oleaginous foods with calcium amino acid chelate complexes and calcium amino acid malic acid chelate complexes.
  • the calcium amino acid chelate complexes and calcium amino acid malic acid chelate complexes of the present invention are stable, palatable, and bioavailable.
  • calcium is an essential element for formation of bones and teeth in animals, including humans.
  • calcium is the most abundant mineral in the body, approximately 99% of the body's calcium is found in the bones and teeth providing an exchangeable pool of calcium. The remaining one percent is widely distributed in cells and body fluids and is responsible for the regulation of a number of metabolic functions such as nerve impulse conduction, muscle fiber contraction, hormone secretion, blood coagulation, normal heart beat, activation of enzymes, and maintenance of cell membranes.
  • metabolic functions such as nerve impulse conduction, muscle fiber contraction, hormone secretion, blood coagulation, normal heart beat, activation of enzymes, and maintenance of cell membranes.
  • calcium is receiving much attention on the front line of medical science because it has recently been discovered that calcium is one of the most important elements for supporting many life activities.
  • Dairy products such as cream, sour cream, milk, cheese, ice cream, and yogurt and oleaginous foods such as margarine, butter, lards, vegetable oil spreads, and vegetable oils are important parts of the human daily diet.
  • oleaginous foods such as margarine, butter, lards, vegetable oil spreads, and vegetable oils
  • the calcium content found naturally in dairy products and oleaginous foods may be acceptable if consumed at high quantities, there is great public interest in the consumption of calcium fortified dairy products and oleaginous foods that contain a relatively high percentage of stable, palatable and bioavailable calcium. It is common practice to fortify food products with calcium sources, some of which are insoluble and some of which are soluble at or near neutral pH levels.
  • an amino acid chelate as "the product resulting from the reaction of a metal ion from a soluble metal salt with amino acids having a mole ratio of one mole of metal to one to three (preferably two) moles of amino acids to form coordinate covalent bonds.
  • the average weight of the hydrolyzed amino acids must be approximately 150 and the resulting molecular weight of chelate must not exceed 800.”
  • amino acid chelates show enhanced bioavailability as compared to non-chelated minerals. Moreover, it is also known that this increased bioavailability is the result of the active transport of amino acid chelates from the digestive tract and into the blood stream.
  • the chelated mineral ions are absorbed through the intestinal lining and into the blood stream, utilizing the amino acids as active transport carriers. More specifically, amino acid chelates are absorbed intact by mucosal cells in the intestines through active transport as is disclosed in U.S. Patent No. 4,863,898.
  • inorganic calcium salts are ionic, they cannot make use of this active transport mechanism, thereby limiting absorption. Therefore, ingested inorganic calcium salts are less bioavailable than the corresponding calcium amino acid chelates. This is in part due to the fact that competition of ions for active sites and the resulting suppression of one nutritive mineral element by another are both avoided.
  • amino acid chelates can be prepared from metal ions which do not come from soluble salts.
  • U.S. Patent Nos. 4,599,152 and 4,830,716 both disclose methods of preparing pure amino acid chelates using metal sources other than soluble metal salts. Additionally, in U.S. Patent No. 5,516,925, methods of preparing amino acid chelates having improved palatability are also disclosed.
  • dairy products and oleaginous foods such as cheese, yogurt, ice cream, cream, milk, margarine, oils, etc.
  • dairy products and oleaginous foods such as cheese, yogurt, ice cream, cream, milk, margarine, oils, etc.
  • fresh skim and whole milk both contain approximately 118 mg of calcium per 100 g of milk.
  • milk is advantageously consumed by those persons who may be most in need of an adequate calcium intake including people who are dieting and women who are pregnant or middle aged.
  • U.S. Patent 4,784,871 a calcium fortified yogurt is disclosed.
  • an acid soluble salt is added to the fruit flavoring prior to combining the flavoring with the yogurt base.
  • the preferred calcium salt used is tricalcium phosphate, dicalcium phosphate, and hydrates thereof. Further, the amounts used are visually undetectable.
  • U.S. Patent 5,449,523 a calcium fortified yogurt is disclosed. In that patent, the calcium source is added to the yogurt milk base prior to pasteurization without undesirable precipitation.
  • the process comprises preparing a yogurt base mix comprised of a fermentable dairy ingredient, a calcium source, a chelating agent, and/or an alkaline agent.
  • the chelating and/or alkaline agents are added in amounts to keep the pH of the yogurt base mix above 6.7 prior to pasteurization.
  • the preferred chelating agents are alkali metal citrates which have the primary task of moderating the pH level.
  • the present invention is drawn to compositions and methods of preparing oleaginous or highly lipid foods emulsified with a calcium amino acid chelate complex or a calcium amino acid malic acid chelate complex. Even when these chelate complexes are incorporated into the various dairy products and oleaginous foods, they are stable and maintain appropriate organoleptic properties, i.e., color, texture, taste, smell, and consistency are acceptable.
  • the calcium amino acid chelate complexes of the present invention are prepared by reacting at least one calcium compound, an amino acid ligand, a pH adjuster, and, optionally, a stabilizing/suspending agent in an aqueous environment at a pH from about 6.5 to 9.
  • the calcium amino acid chelate complex should have an amino acid ligand to calcium molar ratio of about 1 : 1 and a calcium content from 15 to 22% by weight. Further, the calcium amino acid chelate complex must have a coordinate covalent bond between the ⁇ -amino group of the amino acid ligand and the calcium ion.
  • a first embodiment is prepared by reacting calcium carbonate, an amino acid, and phosphoric acid in an aqueous environment producing a calcium amino acid chelate complex having about a 1 : 1 amino acid ligand to metal molar ratio.

  • a third embodiment may be prepared by reacting calcium oxide, calcium chloride, calcium carboxymethylcellulose (CMC), an amino acid, and phosphoric acid in an aqueous environment producing a calcium amino acid chelate complex having about a 1 : 1 amino acid ligand to metal molar ratio.
  • a fourth embodiment may be prepared by reacting calcium oxide, calcium chloride, an amino acid, and phosphoric acid in an aqueous environment producing a calcium amino acid chelate complex having about a 1 : 1 amino acid ligand to metal molar ratio.
  • the calcium amino acid malic acid chelate complexes are prepared by reacting calcium, an amino acid, and malic acid in water.
  • the product produced has an amino acid to calcium content molar ratio from about 1 :2 to 1:1.
  • malic acid is complexed to the calcium amino acid product at a malic acid to calcium content molar ratio from about 1 :2 to 2: 1. It is believed that the malic acid may complex directly with the calcium and/or form a complex with the calcium amino acid chelate.
  • the terms "palatable” and “improved palatability” mean that compositions for calcium fortification of oleaginous or highly lipid foods of this invention are substantially lacking the metallic aftertaste or disagreeable flavor of prior art calcium fortified products to the extent that they have a more pleasant taste to the consuming warm-blooded host, i.e., an animal or human being. This is not to say that these calcium fortified dairy products or oleaginous foods are completely lacking flavor or taste.
  • Bioavailable means, for purposes of this invention, that the calcium source is available to the body.
  • amino acid chelate means, for purposes of this invention, that the amino acid forms a heterocyclic ring with the metal as the closing member. Typically, a coordinate covalent bonds exist between the metal ion and the ligand at the ⁇ - amino group. However, either ionic bonds, covalent bonds, and/or coordinate covalent bonds may exist between the carboxyl oxygen group and the metal ion.
  • Amino acid chelate complex means that as the pH level of the calcium amino acid chelate is lowered, the reaction between the ⁇ -amino group and the calcium remains covalent, but the bond between the carboxyl oxygen and the calcium center becomes more ionic and less covalent.
  • amino acid chelate and “amino acid chelate complex” may be used interchangeably, both of which refer to amino acid ligands bonded to metal ions such that a heterocyclic ring is formed with the ⁇ -amino nitrogen being covalently bonded to the metal ion.
  • the pH adjuster may act merely to facilitate the reaction or may actually be complexed to the calcium amino acid chelate complex.
  • Calcium amino acid malic acid chelate complex is a calcium amino acid chelate complex wherein malic acid, which acts in part as a pH adjuster, is preferably also complexed to the calcium amino acid chelate complex.
  • “Stable” means that the fortificant of the present invention will not significantly alter the shelf-life of the oleaginous or highly lipid foods to which the amino acid chelate complex is added.
  • “Compatible” refers to the fact that the oleaginous or highly lipid foods fortified with the amino acid chelate complexes of the present invention do not significantly affect the organoleptic properties, i.e., sensory properties of the underlying oleaginous food product. For example, taste, texture and smell of the underlying oleaginous or highly lipid foods are not significantly altered in the presence of the amino acid chelate complexes of the present invention.
  • “Dairy products” include, but are not limited to, whole milk, low-fat milk, non-fat milk, flavored milk, cheese, processed cheese, yogurt, frozen yogurt, cream, sour cream, low-fat ice cream, non-fat ice cream, and ice cream.
  • Oleaginous food or “highly lipid food” refers to food products containing a majority of oil or fat such as, but not limited to, margarine, butter, lards, vegetable oil spreads, and all kinds of edible plant oil and oil dressings.
  • the present invention is directed toward compositions and methods of making and preparing calcium amino acid chelate complexes for fortification of dairy products and oleaginous foods. Additionally, compositions and methods of making calcium amino acid malic acid chelate complexes are also disclosed that can be used to fortify oleaginous foods.

  • Other ligands may include dipeptides, tripeptides, and tetrapeptides formed by any combination of the aforementioned amino acids. Glycine is particularly preferred as the chelating ligand.
  • the pH adjuster may be phosphoric acid, citric acid, malic acid, lactic acid, and/or acetic acid. Other possible adjusters and/or buffering agents may also be used.

  • Products such as whole milk, low-fat milk, non-fat milk, flavored milk, cheese, processed cheese, yogurt, frozen yogurt, cream, sour cream, low-fat ice cream, non-fat ice cream and ice cream, margarine, butter, lards, and oils are illustrative. It is important to consider that each of these dairy products and oleaginous foods present different challenges in suspending various calcium sources within that product. For example, with milk, there may be more difficulty in suspending the calcium source over long periods of time than would be the case with yogurt or margarine. Therefore, selection of the calcium amino acid chelate complex, pH balance, and/or use of a suspending agent may require some adjustment with respect to each individual product.
  • the calcium fortified dairy products and oleaginous foods of the present invention may have suspended therein a calcium amino acid chelate complex ranging from about 0.01 to 5% by weight based upon the weight of the respective dairy product or oleaginous food. However, weight ranges from 0.1 to

In such an instance, either a six membered ring or, preferably, a five membered ring may be formed. However, this is merely one proposed mechanism of attachment. It is notable that the malic acid may complex directly with the calcium and/or with the calcium amino acid chelate as long as the calcium amino acid chelate complex is comprised of calcium, an amino acid and malic acid in the prescribed ratios.

The product was pasteurized at 195°F for 3 to 6 minutes and homogenized at 1000 psi. The product was then cooled to 107-112°F, inoculated with the starter culture and held in a tank at from 105 to 108°F until a pH of 4.5 was reached. Next, the product was gently agitated and cooled to 60-65°F, mixed with fruit and flavoring and then packaged in a container. Finally, the yogurt product was cooled to 38- 40°F.
  • a fourth embodiment of a calcium amino acid chelate complex was prepared by evenly splitting 2070 pounds of water into two tanks (1035 pounds in each tank). To the first tank, 378 pounds of glycine was added and blended for 15 minutes forming a clear solution. To the second tank, 252 pounds of calcium oxide and 50 pounds of calcium chloride were added to the water and blended for 15 minutes maintaining the temperature below 140°F forming a milky solution. The contents of both tanks were then combined, blended and held for 30 minutes at 140°F. Once this process was complete, 322.6 pounds of phosphoric acid (85%) was slowly added to the mixture. The addition of phosphoric acid caused the mixture to heat up, but the temperature was maintained at about 150°F. After about 2/3 of the phosphoric acid was added, the product began to thicken so the continued addition of the phosphoric acid was done slowly with vigorous agitation. The product was then allowed to react to completion reaching a pH of about 7.5.
  • Vigorous agitation was maintained during this process.
