Abstract: Potato starch was used as a partial substitute for gelatin and sodium carboxymethyl-cellulose (CMC-Na) to produce ice cream. Its effect on overrun, melting rate and sensory quality was investigated. Using one-factor-at-a-time and orthogonal array design methods, the optimal formulation of ice cream was determined as follows: 4% potato starch, 0.1% CMC-Na, 0.3% monoglyceride and no gelatin. The final product was homogeneous, tasted smooth and delicate and had desired overrun and melting resistance.

Key words: potato starch；ice cream；overrun；melting rate；sensory evaluation

摘要： 用马铃薯淀粉取代明胶和羧甲基纤维素钠（CMC－Na）生产冰淇淋。以冰淇淋的膨胀率、融化率和感官评分为考察指标，研究马铃薯淀粉对冰淇淋品质的影响。通过单因素试验及正交试验确定马铃薯淀粉在冰淇淋生产中最佳用量。结果表明：当马铃薯淀粉添加量4％、CMC—Na添加量0．1％、单甘酯添加量0．3％、不添加明胶时，生产的冰淇淋组织状态均匀一致，口感柔滑细腻，具有理想的膨胀率和适当的抗融性。
