Abstract:

In this study, the emulsifying properties and applications of transglutaminase (TG)-modified soybean protein isolate in ice cream were explored. The formula of ice cream with modified soybean protein isolate consisted of 12% sugar, 8% milk powder, 3% butter, 3% TG-modified SPI, 0.1% CMC, 0.1% monoglycerides and 0.2% gelatin. The ice cream made from this optimal formula was found to be good in expansion rate, melting rate and sensory attributes. Compared with ordinary ice cream, TG modified SPI exhibited a decrease in the consumption of milk powder, emulsifier and stabilizer and an improvement in the nutritional value and a reduction in the production cost of ice cream.

Key words: transglutaminase, soybean protein isolate, ice cream, expansion rate, melting rate
