title: Phytoconstituents and stability of betalains in fruit extracts of Malabar spinach (Basella rubraL.).
abstract: This study aimed to assess the nutrient composition, minerals, and stability of betalains pigment from fruit extracts ofBasella rubra. The proximate composition included total carbohydrates (1.64 g), protein (51 mg), total lipid (1.38%), moisture (81.76%), niacin (0.5 mg), ascorbic acid (89.33 mg), and total tocopherols (1.27 mg) in 100 g fresh deseeded fruit. Total dietary fibre of 32.52 g and soluble dietary fibre of 12.34 g in 100 g dry deseeded fruits. Fatty acid composition of dry deseeded fruits comprised 57.52% SFA, 20.62% MUFA and 22.28% PUFA. Pigment (betalain) rich fruit extracts showed excellent stability over 20 days of storage under varied pH, temperature, light, acids, salts and sugars.B. rubrafruit was observed as a potential source of nutrients and betalains as a functional food.
