摘要
以降低大豆卵磷脂产品的含水量为目标,对大豆卵磷脂进行了真空冷冻干燥的实验研究。通过单因素实验,探讨了不同预冻温度、含水量、冻干时间以及处理量等对卵磷脂产品含水量的影响。最佳工艺参数为预冻温度-35℃,含水量50%,冻干时间7h及处理量8.1kg/m2,得到的冻干产品含水量低于德国Lipoid公司产品含水量。
To reduce the water content of soybean phosphatidylcholine （PC） product, the vacuum ireeze-drying of soybean phosphatidylcholine was conducted. The effects of pre-freezing temperature, water content of raw material, drying time and loading capacity on the water content of freeze dried PC were studied. The optimum operation conditions were freeze temperature - 35℃, the water content of raw material 50%, drying time 7 h and loading capacity 8.1 kg/m^2. The water content of freeze-dried product was less than that of the commercial product made by German Lipoid GmbH.
