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

Abstract

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.

Characterization of major betalain pigments -gomphrenin, betanin and isobetanin from Basella rubra L. fruit and evaluation of efficacy as a natural colourant in product (ice cream) development

“…7) with retention of 86.63 % colour. Similar studies on betalains efficacy in product development by using pigment rich extracts of pigeon berry was reported (Khan et al 2014).…”

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

“…There is a great impetus to identify new biomolecules with promising activity from fruits, because, as natural ingredients they have a proven benefit for human health (Khan et al 2012;Harsha et al 2013) and turn out to be new opportunity for food processing industry. Recent studies have shown fruits from less-known and unexplored plants as excellent source of nutrients and biologically active compounds for food and non-food applications (Khan et al 2011(Khan et al , 2015. Basella rubra L. (Basellaceae), commonly called as Indian or Malabar spinach is found in tropical and sub-tropical areas (Wealth of India 2000).…”

“…Interestingly, many plants accumulate betalains, but only two (B. vulgaris and the prickly pear Opuntia ficus-indica) are approved to be used in food (Delgado-Varges and Lopez 2002). Due to the red-violet colour of the fruits of B. rubra, and its numerous health benefits (Lin et al 2010;Khan et al 2012Khan et al , 2015Kumar et al 2015b), there is a need to investigate the stability aspects of pigment extracts from fruits of B. rubra that helps to promote it as an ingredient in functional food formulations. Accordingly, the aim of the study was to investigate the phytoconstituents, minerals composition and stability of pigment from the ripened fruits of B. rubra.…”

Fruits of Ixora coccinea are a rich source of phytoconstituents, bioactives, exhibit antioxidant activity and cytotoxicity against human prostate carcinoma cells and development of RTS beverage

“…Various edible fruits are described to be excellent sources of natural pigments, namely, anthocyanins (Khan et al, 2014;Sri Harsha et al, 2013), betalains (Kumar, Arya et al, 2020;Kumar, Manoj, Giridhar, Shrivastava et al, 2015), or carotenoids (Khan et al, 2011a(Khan et al, , 2011b and contribute a lot to various health benefits because of their rich antioxidant potential (Khan et al, 2011a(Khan et al, , 2011bKumar, Manoj, Giridhar, Shrivastava et al, 2015). In the present study, the fruit extracts of I. coccinea possess considerable levels of total anthocyanin content, along with carbohydrates and organic acids.…”
