Betalains rich Rivina humilis L. berry extract as natural colorant in product (fruit spread and RTS beverage) development
- 425 Downloads
Rivina humilis L. (Phytolaccaceae) or pigeon berry accumulates betalains in its berries. It is reported that the berries are safe to consume, rich in nutrient content and exhibit efficient biological activity. In this report, Rivina berry extract was used as natural colorant in fruit spread and beverage to evaluate its effect on physicochemical properties and acceptability of the product. Results showed that 68 % color retained in Rivina banana spread after 6 months of storage at 5 °C, though there was reduction in L, a and chroma values. Rivina banana beverage lost redness completely during processing. Microbial analysis of the products indicated that they were safe for consumption. The spread had good overall sensorial quality and was liked by consumers indicating that addition of Rivina berry extract did not alter product quality.
