An investigation was carried out to know the effect of storage temperature on various parameters of extracted pigment from roselle (Hibiscus sabdariffa L.) calyces for edible colour. For knowing the storage stability of extracted pigment, it was kept for 3 months in both ambient and refrigerated conditions. In storage under ambient and refrigerated condition, a decreasing trend were observed in the anthocyanin content, titratable acidity, total antioxidants in the extracted pigment obtained by different methods of extraction upon storage under both conditions. | Effect of storage temperature on various parameters of extracted pigment from roselle (Hibiscus sabdariffa L.) calyces for edible colour
