Betalains rich Rivina humilis L. berry extract as natural colorant in product (fruit spread and RTS beverage) development.

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.
