A method for extraction of anthocyanins and composition thereof

Background:
Pure anthocyanin from grape variety medika:

• We extracted and isolated pure anthocyanins from grape variety medika
• The extraction procedure for anthocyanin from medika was optimized
• The unique combination of anthocyanin from medika was established through HR-LC-MS/MS analysis
• The antioxidant potential of this anthocyanin was established through DPPH, FRAP or ABTs assays
• The in-vitro and invivo anticancer activity established against colon cancer. Spray dried formulation of anthocyanins form medika:
• Micro encapsulated formulation of anthocyanin of 10, 15 and 20% ai was prepared through spray drying
• The formulation contains different constituents like maltodextrin, gum arabica and citric acid etc.
• The release kinetics of these formulations at stomach pH, intestinal pH and at 7.4 pH was established
• The anti-oxidant potential of these formulations were established through DPPH, FRAP or ABTS assays.

Technology Details:

• The innovation give value addition to the grape
• It provide higher anti-oxidant potential spray dried formulation of anthocyanins
• The innovation provides a simple cost-effective method for extraction of anthocyanins from grape.
