油脂的酸败是油脂因水解而产生游离脂肪酸,以及脂肪酸进一步氧化分解所引起的变质现象。油脂酸败的原因一般有两个,其一为生物性的,即动植物织残渣和微生物的酶类所引起的水解过程;其二则属于化学变化,即在空气、日光、高温和水的作用下,发生的水解及不饱和脂肪酸的自身氧化,这两种过程往往是同时发生的。醉仙鸭http://www.zuixianya666.com/
Fat rancidity grease due to hydrolysis produce free fatty acids, and fatty acid and further oxidation and decomposition caused by the deterioration phenomena. There are two general causes of rancidity, one is biological, including hydrolysis of plant residue and microbial enzymes fabric caused by the chemical change; it belongs to, in the air, sunlight, high temperature and under the action of water, the hydrolysis and the unsaturated fatty acid from oxidation, this the two process is often occur at the same time.
加工烤鸭、烤鸡、烤肉的师傅通常会在用金属托盘来收集这些食物在烘烤过程中流出的油脂,油脂从肉中渗出,再流到托盘上,往往会携带很多杂质,如木炭燃烧后的灰烬、空气中的灰尘、烤鸭表面的调味料以及烤焦了的食物残渣等等。
Processing Roasted Duck, Roast Chicken, barbecue chef usually in the metal tray to collect the food out in the baking process of oil, grease exudation from the meat, then flows into the tray, often carry a lot of impurities, such as charcoal ash after combustion, the dust in the air, the surface of the Roasted Duck seasoning and scorched food residue etc/
加工烤鸭的烤炉温度很高,而油脂在高温烹调条件下可能发生两类变化,产生多环芳烃类致癌物和高温氧化聚合毒物。肉类中的饱和脂肪在熏烤和烧烤条件下会产生多种致癌物质,其中包括强力致癌的苯并[a]芘类物质。在明火加热条件下,致癌物质的产生更为严重。醉仙鸭http://www.zuixianya666.com/
Processing Roasted Duck oven temperature is very high, and oil in high temperature cooking two class may change condition, produce polycyclic aromatic hydrocarbon carcinogens and high temperature oxidation polymerization. The saturated fat in meat will produce a variety of carcinogenic substances in the baking and roasting conditions, including strong carcinogenic benzo (a) pyrene substances. In the open fire heating conditions, carcinogenic substances produced more serious.
