摘要: 为探讨制备工艺与搅打鲜奶油品质之间的内在关系,利用激光粒度分布仪研究了均质压力对搅打鲜奶油乳状液制备过程中脂肪球粒度分布的影响规律,采用SPSS 13,0分析了搅打充气过程中脂肪球粒度分布和脂肪部分聚结率及搅打起泡率之间的关系.结果表明:均质压力越高(20~60MPa),脂肪球粒径越小;在搅打充气过程中,脂肪部分聚结率随均质压力升高而增加;均质压力为60MPa的搅打鲜奶油的搅打起泡率最小,均质压力为50MPa时搅打起泡率最大,搅打鲜奶油的最适均质压力为40~50MPa.

关键词: 搅打鲜奶油, 均质压力, 脂肪, 部分聚结, 起泡率

Abstract:

In order to reveal the interrelation between the preparation conditions and the qualitv of whipped cream.the effect of homogeneous pressure on the size distribution of fat globules in the emulsion during the preparation of whipped cream was investigated by means of the laser light scattering instrument.The relationship between the size distribution of fat globules and the partial coalescence rate as well as foam overrun of fat during the whipping process was then analyzed with SPSS 13.0 software.The results indicate that(1)the size of fat globules increases with the homogenous pressure within the range of 20 to 60 MPa;(2)the partial coalescence of fat is acce1erated bv Increasing homogenous pressure during the whipping process;(3)the overrun of whipped cream reaches its mini-mum and max m“m alue respectively at the homogenous pressures of 60 and 50 MPa;and(4)the optimal ho-mogenous pressure for whipped cream is 40~50 MP

Key words: whipped cream, homogeneous pressure, fat, partial coalescence, overrun
