The recycling price of the remaining frying waste oil in catering enterprises is one catty more than that of 1.3 yuan.

"gutter oil" is strictly forbidden to be used in the field of edible oil. However, some people do produce and process "gutter oil" privately and sell it as edible oil to some small restaurants at low prices, which brings great harm to people's body and mind.

Therefore, the name "gutter oil" has become synonymous with all kinds of inferior oils that do harm to people's lives. After the waste oil enters the edible oil, all kinds of bacteria and viruses in it will directly enter the human body, and it is easy to get hepatitis A, stomach cancer, lung cancer, brain diseases and gene mutation, so the price of waste oil recovery is very low.

attention to daily edible oil

the acid value of edible vegetable oil should not exceed 3, and it should not exceed 5 during frying. The allowable acid value limit of "vegetable crude oil" in the standard is much higher because these oils are not refined and contain more free fatty acids. This is also the reason why "self-pressed oil" and "earth-pressed oil" have many impurities and low quality.

The requirement for peroxide value in the standard is not more than 1.25, but there is no requirement for detection of peroxide value in frying process. That is to say, the peroxide value is not suitable to detect the quality change of oil during frying. Suitable indicators are acid value and polar components.
