NATURALLY DERIVED COLOUR STABILIZER
The present invention relates to the prevention of colour instability or colour fading. It is directed to the use of phloretin, a naturally derived colour stabilizer, as well as to a method of preventing colour instability or colour fading in a colored beverage or food product by including said stabilizer in said product.
1 - 13 . (canceled)
14 . A method for stabilizing color in a colored beverage or food product, comprising:
adding a compound of formula (I) or a derivative or salt thereof
to a colored beverage or food product to stabilize the color in the colored beverage or food product.
15 . A method for decreasing color instability or color fading in a colored beverage or food product, comprising:
adding of a compound of formula (I) or a derivative or salt thereof
to a colored beverage or food product to decrease color instability or color fading in the colored beverage or food product.
16 . The method of claim 14 , further comprising adding ascorbic acid in combination with said compound (I) or a derivative or salt thereof to said colored beverage or food product.
17 . The method of claim 14 , wherein the colored beverage or food product contains naturally derived color or a synthetic equivalent of the naturally derived color or a synthetic color.
18 . The method of claim 17 , wherein said naturally derived color is selected from the group of Annatto extract, astaxanthin, dehydrated beets, canthaxanthin, caramel, Beta-apo-8′-carotenal, beta-carotene, cochineal extract, carmine, sodium copper chlorphyllin, ferrous gluconate, ferrous lactate, grape color extract, enocianina, Haematococcus algae meal, fruit juice, vegetable juice, carrot oil, corn endosperm oil, paprika, paprika oleoresin, Phaffia yeast, riboflavin, saffron, titanium dioxide, turmeric oleoresin, bixin, and combinations thereof.
19 . The method of claim 17 , wherein said synthetic color or said synthetic equivalent of the naturally derived color is selected from the group of FD&C Blue No. 1, FD&C Blue No. 2, FD&C Green No. 3, Orange B, Citrus Red No. 2, FD&C Red No. 3, FD&C Red No. 40, FD&C Yellow No. 5, FD&C Yellow No. 6, Citrus Red No. 2, D&C Red No. 28, D&C Yellow No. 10, synthetic iron oxide, ferrous gluconate, ultramarine blue, ultramarine green, ultramarine violet, ultramarine red and combinations thereof.
20 . The method of claim 14 , wherein said compound (I) or a derivative or salt thereof is present in an amount ranging from about 0.1 ppm to about 500 ppm.
21 . The method of claim 14 , wherein said compound (I) or a derivative or salt thereof is present in an amount ranging from about 1 ppm to about 100 ppm.
22 . The method of claim 14 , wherein said compound (I) or a derivative or salt thereof is present in an amount ranging from about 10 ppm to about 50 ppm.
23 . The method of claim 16 , wherein ascorbic acid is present in an amount ranging from about 0.1 ppm to about 500 ppm.
24 . The method of claim 16 , wherein ascorbic acid is present in an amount ranging from about 1 ppm to about 300 ppm.
25 . The method of claim 16 , wherein ascorbic acid is present in an amount ranging from about 50 ppm to about 200 ppm.
26 . A method for stabilizing color, decreasing color instability or color fading in a colored beverage or food product, comprising:
combining an effective amount of a compound of formula (I) or a derivative or salt thereof
or a coloring composition comprising an effective amount of the compound of formula (I) or a derivative or salt thereof with the finished product or with a precursor thereof to stabilize the color, decrease color instability or color fading in the colored beverage or food product or with a precursor thereof.
