摘要: 利用蛋清基脂肪替代品降低高脂冰淇淋中的脂肪,开发低脂冰淇淋。通过理化性质测量、感官评价和微观结构的观察,综合分析脂肪替代品在冰淇淋中的代脂肪效果。结果表明:脂肪替代率15%时,冰淇淋的气泡和脂肪总聚集数量多,膨胀率提高,从54.9%增大到72.6%,而融化率降低,从48.32%降低到24.3%。在脂肪替代率25%~30%时,冰淇淋的口感和接受度降低。因此,脂肪替代率15%时,冰淇淋的可接受度最佳。

Abstract: The purpose of this research was to investigate the feasibility of using egg white-xanthan gum (EW-XG) complex as a fat substitute to reduce the fat content in high-fat ice cream and thus obtain low-fat ice cream. The effect of lipid replacement in ice cream was analyzed on its physicochemical properties, sensory evaluation and microstructure. The results showed that overrun was increased from 54.9% to 72.6% and melting rate was decreased from 48.32% to 24.3% when 15% fat substitute was added. Besides, the amount of bubbles and fat aggregation were increased. However, the taste and acceptance were reduced when 25%–30% fat substitute was added. Therefore, ice cream was best accepted with addition of 15% fat substitute.

Key words: high-fat ice cream, fat substitute, overrun, microstructure
