Close to the Spring Festival, bacon, sausages and other foods full of year-end flavor are particularly popular. However, recently, Sichuan's industrial and commercial system issued a test report: multiple batches of bacon food failed, and the acid price exceeded the standard.
What is the acid price? Professor Zhu Yi, associate professor of the Food Science and Nutritional Engineering College of China Agricultural University, told the reporter that the acid price is an indicator of the degree of fat hydrolysis and it reflects the rancidity of bacon. In general, the smaller the acid value, the better the bacon fat quality and freshness.
In addition to acid prices may exceed the standard, there are hidden dangers of nitrite exceeding standard, microorganisms exceeding the standard, fat oxidation, and excessive benzopyrene. Lap foods are generally added with nitrite, mainly for the sake of bright red color, but some companies add too much, it will increase the risk of cancer; some wax due to improper processing and storage, resulting in excessive microorganisms, and even mildew; wax food processing and During storage, fats are prone to oxidation, resulting in hazel flavor. At the same time, harmful chemicals such as aldehydes and ketones are produced. The long-term consumption is harmful to health. If it is smoked, it may also lead to excessive benzene propane. Moreover, the salt-fat high-fat and high-salt foods are basically free of nutrients such as vitamins, and their nutritional value is not high. Therefore, do not eat too much even if it is delicious, especially for patients with high blood pressure and high blood pressure.
Of course, as a representative food for the Chinese New Year, preserved foods can also be tasted. However, I must remember to put more water when cooking and cook more. Boil can dissolve nitrite, excessive salt and fat in bacon. It's better to cook for longer, not less than 30 minutes each time.
Also, be extra careful when shopping. First of all, pay attention to the integrity of the package, there is no air leakage or bag, the color is not too bright. Second, the surface should be dry, tough and elastic, with no visible dents after finger pressure. Finally, it is important to smell. Haw taste, sour taste, musty smell of meat foods do not buy.
