After food passes deepfry, improved its color, sweet, flavor, fetching appetite. Spring roll, deep-fried twisted dough sticks, oily San child, shrimp of scamper fish, blast, it is restaurant, dining-room, dining room even the standing dish on domestic table. On big archives, night fair fewer not raise on oily boiler, fish, flesh, bean curd, potato, apple, banana can enter boiler one blast. But from the point of nutrient respect, deepfry of unfavorable and long-term overmuch edible kind food. Deepfry kind food not only nutrient value is very low, the poisonous and harmful material that contains among them also can give human body health to bring very great harm.
Deepfry is food ripe in the effect that high fever suffers in boil oil, what use oil lukewarm it is ℃ of ~300 of 150 ℃ normally between, below such high temperature, nutriment is destroyed very quickly. Vitamin C disappears almost completely, vitamin B2 and Buddhist nun overcome acerbity loss most, the indispensible fatty acid in grease is many loss, protein digestive absorptivity drops greatly. The nutrient value of deepfry food and original provision photograph are compared not as good as former 1/3, but, the loss of nutrient value is the one fraction that deepfry food endangers only, another main factor is to come from the poisonous and harmful material that has very big menace to human body health at what exist among them.
Much annulus aromatic hydrocarbon kind material
Deepfry of high temperature of deepfry food classics is machined and become, the incomplete combustion of organic matter can produce much annulus aromatic hydrocarbon kind material, its are represented namely 3, 4- benzene and Bi. Contain in the lampblack that edible oil produces below high temperature action 3, 4- benzene and Bi kind material. After food classics deepfry, the retention period below the environment in thick lampblack is too long, or because do not change for a long time,fry place uses oil, easy by 3, 4- benzene and Bi pollution, make food with such deepfry, long-term edible cans be imagined to the harm of human body.
Benzene and Bi is a kind of organic compound that has the apparent effect that cause cancer, easy cause the malignant tumor such as lung cancer, cancer of the stomach, pollute atmosphere already, endanger human body health again. Ever the experiment makes clear, benzene and Bi besmear is on the ear of bunny, this grew tumor locally after 40 days. The benzene in human surroundings and every add Bi content 1% , the mortality of lung cancer rises namely 5% . And often edible by benzene and the deepfry that Bi pollutes, barbecue kind food, carcinogen can be inside body save up, increase the risk that has malignant tumor.
