宠物饲料级

>适用范围:

牛油、羊油、猪油、马油、动物内脏、鸡鸭油、鱼油等加工动物饲料油等

Scope ofapplication:

Butter, sheep fat, lard, horse oil, animal offal, chicken and duck fat, fish oil and other

processed animal feed oil.

工艺说明:

动物油脂细胞中的油脂在热作用下，会从固态变为液态。加热动物脂肪会降低油脂的粘

度，并降低其表面张力,这是热分子运动的结果，也是分子间凝聚力减弱的结果。凝聚力减

弱会使油脂易于从细胞中析出，并能使单个细胞的油脂液滴汇聚成大的团块，同时由于比

重的不同，油脂与蛋白质分离。

Process description:

The oils in animal fat cells change from solid to liquid under the action of heat. Heating animal

fat reduces the viscosity of the oll and reduces its surface tension, which is the result of the

movement of hot molecules and the weakening of intermolecular cohesion. Weakened cohesion

makes lipids easy to precipitate from cells, and allows lipid droplets from individual cells to

converge into large clumps, while fats are separated from proteins due to diferent specific

gravity.
