| description | Beta vulgaris or beetroot contained high pigment of betalains that are used as food colorants and food
additives due to their health-promoting properties. The extraction of natural colorant compound from beetroot under
chemical- based extraction was identified as an alternative source of commercial synthetic colorant. Beetroot is
generally processed before consumption which influences the stability of betalains as well as affects the acceptability
and health properties. Therefore, this study aimed to investigate the antioxidant activities of betalain-containing extracts and the influence of UV irradiation and heat on the betalain pigment at different concentrations, temperature and period of time. The impact of these factors was evaluated with spectrophotometric absorbance value on the basis of betalain chromaticity. The results of the DPPH antioxidant test revealed that the scavenging activity of betalain increasing proportional to its concentration and the highest 50% inhibition activity was recorded at 77.48%. At 3.0 g/l betalain concentration, the highest chromaticity value was recorded whereas temperature between 10 to 30°C was the most stable betalain pigment against heat stress. However continuous exposure of betalain pigment towards UV irradiation was found to cause discoloration of the samples. |
