但由于米糠中含有解脂酶,如果钝化处理不及时或者米糠保存温度较高,米糠中脂肪酸解过程加速。
Lipase could lead the oil hydrolyzed if the rice bran not passivated in time especially in the high temperature, which in order to increase the acid value of RBO.
油脂是供能最高的一类营养物质,菜籽油在我国来源广泛,本文即以以1,3-定向脂肪酶为催化剂,使混合底物菜籽油和辛酸在无溶剂体系中进行酸解反应,以制备供能较低的结构脂质。
The research take 1,3-directional lipase as catalyst, which catalyzes acidolysis reactions of rapeseed oil and caprylic acid in free solvent to produce structured lipid of lower energy.
米糠通过挤压膨化,一方面使米糠中的解脂酶在瞬间高温和高压作用下被钝化,防止米糠油的酸败;
The extrusion puffing, on the one hand, can make solution lipase in the rice bran passivated under high temperature and high pressure condition, then prevent the rice bran oil rancidity;
