ANTHOCYANIN RICH READY-TO-SERVE BEVERAGE CO-PIGMENTED WITH BLACK SOYBEAN EXTRACT AND ITS EFFECT ON ANTIOXIDANT PROFILE AND COLOR STABILITY

Abstract
Abstract - Copigmentation is the formation of molecular connections or complexes by pigments and other non colored organic substances in solution. It usually leads in an increase in absorbance and, in certain circumstances, an increase in the wavelength of the pigment's maximum absorption.The antioxidant content Total Phenolic Content, Total Flavanoid Content, Total Anthocyanin Content, Monomeric and Polymeric color were done by Aluminum Chloride assay, Folin-Ciocalteu assay, pH differential technique and Bisulfite bleaching assaycorrespondingly. Antioxidant activities DPPH IC50 and FRAPcontent was estimated. Browning index, hyperchromic and bathochromic shift was equated by equation The results revealed that among four Formulated Beverages, FB4 (40:42:12:4:2) exhibited significantly high total anthocyanin (9070.57mg Cy-3-G/L), Cyanidin-3-Rutinoside (2458mg/L), Pelargonidin-3-Glucoside (1080.6mg/L), total flavonoids (10.6mgQCE/ml) as compared to FB1 (40:54:0:4:2) oftotal anthocyanin (5143.52mg Cy-3-G/L), Cyanidin-3-Rutinoside (2101mg/L), Pelargonidin-3-Glucoside (728.4mg/L), total flavonoids (7.9mgQCE/ml) at p≤0.05level. The antioxidant activities of FB 4 exhibited (22.1± 0.16) IC50 value and and (48.4mgAscE/ml) FRAP content. Estimated values for PC (1.363  0.11), CD (11.9  0.02), %PC (11.40.01), BI (1.58), Hyperchromic (2.444Abs) and Bathochromic shift (564nm) were significantly higher than the estimated values of formulated beverage 1. Thus, these findings indicate that a beverage made from black soybeans, corn silk, and black mulberries is a valuable source of functional beverage with therapeutic potential that could be meant for a large number of customers affected by metabolic ailments.The study aimed to develop Ready-To-Serve (RTS) beverages to enhance anthocyanin-rich beverages and create new value-added products Keywords - Anthocyanin, Antioxidants, Co-pigmentation, Functional Beverages, Black soybean, Black Mulberrry, Corn silk
