Abstract

Abstract : Three different plants ( Solanum indicum, Solanum surattense, and Solanum nigrum ) of Solanaceae family were explored to extract and characterize hydrocolloids in aqueous solution. S. indicum fruit fractions bring in maximum hydrocolloid yield of 21.39 ± 0.42% based on % dry weight of the sample. The observed order of extracting hydrocolloid yield amongst investigating aerial parts of S. surattense, S. nigrum, and S. indicum (% dry weight) is fruits > stem > leaves. Maximum protein (22%) and starch (0.85%) contents were observed in fruit fractions of S. nigrum and S. indicum, respectively. Among the functional characteristics, the fruit fraction of S. indicum has higher water-holding capacity (24.80%), oil-holding capacity (2.96%), emulsifying activity (90%), emulsion stability (70%), foaming capacity (65%), and foaming stability (90%). Monosaccharide profiling results showed the presence of glucose, galacturonic acid, galactose, glucuronic acid, arabinose, and xylose in extracted fractions. The findings propose that hydrocolloids (extracted with water) are cost-effective and would be potential candidate as a substitute for pectin added into foamy and frothy food products and frothy beverages.
