Definitions

  • the present invention provides food colour compositions containing natural pigments and vitamins, and their methods of preparation.
  • Colouring agents are commonly used in the manufacturing of food products. There are three main classes of colouring agents in foods: natural colours, browning colours, which are produced during cooking and processing, and additives.
  • the principal natural colours most of which, in refined form are used as additives, are the green pigment chlorophyll, the carotenoids, which give yellow to red colours, and the flavonoids, with their principal subclass the anthocyanins, which give flowers and fruits their red to blue colours.
  • Natural colours are derived or come directly from plant or animal sources, such as: seeds (annatto); roots (turmeric); carbohydrates (caramel); leaves and stems (henna); vegetable (such as red cabbage, beetroot juices, and carrot oil extract); fruits (grape juice); algae (beta carotene); or insects (carmine).
  • the patent application EP 1 336 341 A2 discloses the use of a ready-to-use water dispersible composition comprising the dispersion of a hydrophilic natural pigment in the form of bodies of an average size which is at the most 10 ⁇ m, said bodies being dispensed in the absence of a surface active substance in an aqueous phase comprising a hydrocolloid, the composition containing in excess of 10% by weight of water, in the manufacturing of an edible product whereby the composition is dispersed in an aqueous phase of said product.

  • the present invention relates to the fortification of food products which use colour pigments with vitamins.
  • a vitamin is an organic compound required by the body, necessary for good health, growth and normal metabolism. In their absence the animal develops certain deficiency diseases or other abnormal conditions. Vitamins might also be defined as chemical compounds of an organic nature which are essential constituents of the food of animals where they are present in minimal amounts.
  • Vitamins are necessary for life since they are important regulators of many compounds and cannot be stored by the body, therefore requiring regular consumption. Vitamins are traditionally classified as hydrosoluble vitamins (water soluble vitamins) which include vitamin C (ascorbic acid) and liposoluble vitamins (oil or fat soluble vitamins) which include vitamin E which is in its most common form alpha-tocopherol.
  • hydrosoluble vitamins water soluble vitamins
  • vitamin C ascorbic acid
  • liposoluble vitamins oil or fat soluble vitamins
  • Vitamin D Of the essential vitamins only vitamin D can be manufactured by the body, hence all other vitamins must be derived from our diet.
  • the vitamins required can be found in a sufficient amount in the diet assuming it is normal and well balanced.
  • the modern lifestyle has seen a change in diet and a decline in the consumption of nutrient rich foods along with irregular eating patterns and an increasing reliance on snacking and prepared foods. This outcome poses an increasing difficulty to obtain and assimilate the Recommended Daily Amount (RDA) of vitamins.
  • RDA Recommended Daily Amount
  • Vitamin C also known as ascorbic acid is a water soluble vitamin. Unlike most mammals, humans do not have the ability to make their own vitamin C. Therefore, we must obtain our vitamin C through our diet. Vitamin C is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments, and bone. Vitamin C also plays an important role in the synthesis of the neurotransmitter norepinephrine. Neurotransmitters are critical to brain function and are known to affect mood. In addition, vitamin C is required for the synthesis of carnitine, a small molecule that is essential for the transport of fat to cellular organelles called mitochondria, for conversion into energy. Recent research also suggests that vitamin C is involved in the metabolism of cholesterol to bile acids, which may have implications for blood cholesterol levels and the incidence of gallstones. Vitamin C is also very effective as an antioxidant. Even in small amounts vitamin
  • Vitamin C can protect indispensable molecules in the body, such as proteins, lipids (fats), carbohydrates, and nucleic acids (DNA and RNA) from damage from free radicals and reactive oxygen species that can be generated during normal metabolism as well as through exposure to toxins and pollutants (e.g. smoking). Vitamin C may also be able to regenerate other antioxidants such as vitamin E.
  • the recommended dietary allowance (RDA) for vitamin C is 60 mg daily for men and women.
  • the recommended intake for smokers is 35 mg/day higher than for nonsmokers, because smokers are under increased oxidative stress from the toxins in cigarette smoke. If one consumes too much of a water soluble vitamin, the body will get rid of the excess. This means that the body does not store it for long periods of time. You cannot stock up on it, and you can reach a saturation point quickly, therefore you need vitamin C several times a day.
  • vitamin C is most effective when combined with other nutrients. For example, it has been found that vitamin C and E work together to help stave off Alzheimer ' s disease.
  • Vitamin E a liposoluble vitamin
  • Vitamin E is an antioxidant involved in the metabolism of all cells. It tames dangerous free radicals and helps prevent blood clots and blockage in coronary arteries. Research points to its ability to reduce the risk of chronic diseases, such as heart attacks and some cancers. Vitamin E is also believed to slow the aging process and to help nerve conduction. Most importantly, it works to protect vitamin C and vitamin A.
  • the U.S. Recommended Dietary Allowance (RDA) per day is 10 milligrams of alpha-tocopherol equivalents.
  • RDA Recommended Dietary Allowance
  • tocopherols are founded naturally: alpha, beta, gamma and delta-tocopherol; they are widely distributed in vegetable lipids though animals cannot synthesize them.
  • the synthetic version of vitamin E is not as effective as in its natural form.
  • Alpha-tocopherol has the strongest vitamin E activity.
  • vitamin E is a fat-soluble vitamin, people on low-fat diets can have trouble getting enough of the vitamin. Therefore, dietary fat should be monitored and not go below safe limits.
