| Résumé : |
Data from the characterisation and fingerprinting methods applied show notable qualitative differences in composition of the functional beverage ingredient obtained using Zeta Fraction technology when compared to green and black tea traditional preparations.
Purecentia Camellia sinensis has a higher solids content, a better representation of certain peaks, and a greater diversity of compounds ; in addition, it has a much more higher concentration of L-theanine than traditional black and green tea preparations. Overall, Purecentia Camellia sinensis has much higher concentration than traditional black and green tea preparations, and contains more constituents. Activity of Purecentia Camellia sinensis is over twenty times higher than the best-performing of the tested commercial green tea beverages, and even the 5% Purecentia Camellia sinensis drink prototype surpasses every tested commercial beverage. This suggests that Purecentia Camellia sinensis may be a potent ingredient for adding antioxidant activity to existing beverages, or creating functional beverages using it as a base active ingredient. Cosmetic ingredient Recentia CS retains its antioxidant activity in personal care gel prototype, and helps to preserve antioxidant activity of other components of the formulation. |
