The Beijing News reporter received a report from an internal Pizza Hut employee that the label of food ingredients was often modified in the fast food restaurant to prolong its life, so he undercovered the Pizza Hut kitchen for a month and found that there was indeed such a case. In this case, not only do managers often modify labels to use expired food, but also the oil used in French fries is overdue, and if the polar components exceed the standard, they still have not been replaced, so use “ink oil” with excessive polar components. What effect will it have on the human body?
Generally speaking, the normal edible oil will appear transparent yellow when it is melted. The oil will gradually show deeper and deeper changes. This change is not only caused by the carbon formed by the high temperature carbonization of french fries, but also the increase in some carcinogens in the oil is also the reason for the deepening of the oil. These carcinogens Including various fried meats will produce benzopyrene and heterocyclic amines; fried starchy foods such as potatoes and cereals will produce acrylamide. It can cause gastrointestinal reactions in the short term, and there is a risk of cancer after long-term consumption.
The quantitative index for detecting harmful substances in cooking oil is called polar component detection. The polar component of edible oil refers to the thermal oxidation reaction of edible oil in fried food, Thermal polymerization, thermal cracking and hydrolysis produce some components with higher polarity than normal edible oil molecules (triglycerides). These substances are harmful to the human body, and some may cause cancer. The value of this indicator exceeds 27. It can no longer be used, but the polarized components of cooking oil in Pizza Hut often exceed 30 and continue to be used. Cooking and frying food in such oil will obviously cause damage to the human body.
No matter what kind of enterprise, it should not only pursue profit at the expense of the interests of customers, especially health interests.
