Glycyrrhiza and the prevention of LC-PUFA oxidation
The present invention relates generally to the field of the LC-PUFA containing compositions. For example, the present invention relates to at least partially preventing, inhibiting, reducing and/or stopping the oxidation of LC-PUFA in a composition. An embodiment of the present invention relates to a composition comprising at least one LC-PUFA containing oil and Glycyrrhiza , a part and/or an extract thereof. Another embodiment of the present invention relates to the use of Glycyrrhiza , a part and/or an extract thereof in compositions comprising an LC-PUFA containing oil to at least partially prevent, inhibit, reduce and/or stop the oxidation of LC-PUFA in the composition.
1 . A composition comprising (i) at least one oil comprising long chain polyunsaturated fatty acids (LC-PUFA) and (ii) micronized root of Glycyrrhiza , wherein the composition comprises the LC-PUFA in an amount of about 5-35 weight % of the composition, and wherein a weight ratio of the micronized root of Glycyrrhiza to the LC-PUFA is between about 1:2 and 1:1.
2 . The composition in accordance with claim 1 , wherein the at least one oil is selected from the group consisting of a marine oil, an oil produced by microorganisms, an oil produced by one-celled plants, an oil produced by multi-cellular plants or an oil of animal origin, and mixtures thereof.
3 . The composition in accordance with claim 1 , wherein the composition is a food composition.
4 . The composition in accordance with claim 1 , wherein the LC-PUFA are at least partially present in mono-, di- and/or triglyceride form.
5 . The composition in accordance with claim 1 , the composition further comprising an antioxidant in an amount of about 0.001 weight % to 1 weight %.
6 . The composition in accordance with claim 1 , wherein the composition does not contain any fat source additional to the micronized root of Glycyrrhiza and the at least one oil comprising long chain polyunsaturated fatty acids.
7 . The composition in accordance with claim 5 , wherein the composition comprises about 0.01 weight % to 0.5 weight % of the antioxidant.
8 . The composition in accordance with claim 5 , wherein the antioxidant is selected from the group consisting of glutathione, lipoic acid, uric acid, carotenoids, lycopene, carotene, ubiquinone, polyphenolic antioxidants, resveratrol, flavonoids, galates, sulfites, retinols, nitrites, EDTA, citric acid, phytic acid, and mixtures thereof.
9 . A product comprising a composition comprising (i) at least one oil comprising long chain polyunsaturated fatty acids (LC-PUFA) and (ii) micronized root of Glycyrrhiza , wherein the composition comprises the LC-PUFA in an amount of about 5-35 weight % of the composition, wherein a weight ratio of the micronized root of Glycyrrhiza to the LC-PUFA is between about 1:2 and 1:1, and
wherein the product is selected from the group consisting of a LC-PUFA containing raw material, a nutritional complete formula, a dairy product, a chilled or shelf stable beverage, a mineral or purified water, a liquid drink, a soup, a dietary supplement, a meal replacement, a nutritional bar, a confectionery, a milk or a fermented milk product, a yoghurt, a milk based powder, an enteral nutrition product, an infant formula, an infant nutritional product, a cereal product or a fermented cereal based product, an ice-cream, a chocolate, coffee, a culinary product, tomato puree or salad dressings, a health care product, a cosmetic product, a pharmaceutical product, and a pet food.
10 . The product in accordance with claim 9 , wherein the product is mayonnaise.
11 . The product in accordance with claim 9 , wherein the product further comprises a carbohydrate source and a protein source.
12 . The product in accordance with claim 11 , wherein the protein source is a milk protein.
13 . A method to prevent, reduce, inhibit and/or stop oxidation of LC-PUFA in a composition comprising (i) at least one oil comprising long chain polyunsaturated fatty acids (LC-PUFA) and (ii) micronized root of Glycyrrhiza , wherein the composition comprises the LC-PUFA in an amount of about 5-35 weight % of the composition, and wherein a weight ratio of the micronized root of Glycyrrhiza to the LC-PUFA is between about 1:2 and 1:1, the method comprising:
mixing the micronized root of Glycyrrhiza with the at least one oil comprising LC-PUFA.
