摘要:

探讨转谷氨酰胺酶改性大豆分离蛋白的乳化特性及其在冰淇淋生产中的应用。确定改性大豆分离蛋白冰淇淋的配方为:白砂糖12%,奶粉8%,奶油3%,改性大豆分离蛋白3%,CMC 0.1%,单甘酯0.1%,明胶0.2%。由此制得的冰淇淋膨胀率、融化率和感官指标均比较理想。较普通冰淇淋相比,减少了奶粉、乳化剂和稳定剂的用量,提高了冰淇淋的营养价值,降低了生产成本。

关键词: 转谷氨酰胺酶, 大豆分离蛋白, 冰淇淋, 膨胀率, 融化率

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
