摘要
研究了温度和水分含量对饲用大豆浓缩磷脂黏度的影响,发现Na+能提高浓缩磷脂的黏度,而Ca2+能降低浓缩磷脂的黏度。对于水分含量较低的塑性浓缩磷脂,添加0.4%的氯化钙或添加3%大豆油脱臭馏出物能显著降低低水分塑性浓缩磷脂的黏度,使其流态化。但对于高水分塑性浓缩磷脂,其作用不明显。0.3%的氯化钙和3%的大豆油脱臭馏出物复合使用能使塑性浓缩磷脂的黏度降到2000cPa.s以下,而且长时间保持稳定。
The effects of temperature and moisture content on the viscidity of feed grade soy lecithin were studied. Meanwhile,it was discovered that sodium ion could increase the viscidity of soy lecithin;otherwise, calcium ion could decrease the viscidity of soy lecithin.With the addition of 0.4 % calcium dichloride or 0.3 % soybean oil deodorizer distillate, the viscidity of low moisture content soy lecithin was decreased remarkably and the plastic lecithin was converted into fluidization.However,this method was very limited to plastic soy lecithin with high content of moisture.The modified soy lecithin,which was fluidized by the complex of 0.3 % soybean oil deodorizer distillate and 0.3 % calcium dichloride,had the low value viscidity below 2000 centipoises that was very stable during long time storage.
