Phytoconstituents and stability of betalains in fruit extracts of Malabar spinach (Basella rubra L.)

This study aimed to assess the nutrient composition,
minerals, and stability of betalains pigment from
fruit extracts of Basella 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. rubra fruit was
observed as a potential source of nutrients and betalains as
a functional food.
