Dahe Health News reporter Yang Lu

A few days ago, the media undercover Beijing Pizza Hargo Harmony Plaza store and Wei Gong village store, and found that there were issues such as expired ingredients, tampering ingredients, and overdue use of frying oil in the store, which received widespread attention.

According to reports, the fried oil was obviously black when the oil was abandoned, and the acid price of the oil was nearly doubled.

According to the Bill Shengke China Weibo, the related issues of the media reported by the Beijing Pizza Hut Harmony Plaza and the Weigong Village Store have immediately conducted a close store investigation of the above two restaurants.

What is the acid price of frying oil? What is the harm of acid prices exceeding the standard?

Acid prices can measure the quality of oil

Wang Wen, a nutritional physician of the Nutrition Department of the People's Hospital of Henan Province, said that acid prices mainly reflect the degree of fatty acidity in food, and the excessive acid prices will cause food to produce irritation (Hara flavor).

The acid price itself is not a "toxic" standard. As long as the acid price is within the scope of the national standard, it has no effect on physical health.

"GB 2716-2018 Food Safety National Standard Botanical Oil" stipulates that the acid price of edible vegetable oil is not more than 3mg/g.

Acid prices can measure the quality of oil from the side. The same kind of oil, the smaller the aciding price, the fresher the oil; on the contrary, the more acid prices, the higher the quality of the oil, the more harmful substances in the oil, and the more harmful substances in the oil. The more unhealthy food.

The reason for the excessive acid prices may be related to improper product storage conditions, especially when the storage temperature is high, which can easily lead to fat oxidative acid defeat and cause the acid prices to exceed the standard.

The product of oil is damaged to the human body's various enzymes and affects normal metabolism. If the edible oil that takes for long -term intake of acid prices may not only cause gastrointestinal discomfort, diarrhea, but even liver enlarged and growth and development disorders.

Avoid three aspects of avoiding exceptional prices

How to avoid excessive consumption of oleic acid prices? Wang Wen said that it can start from three aspects: selection, storage and use of edible oil.

✎ ✎

Edible oils are divided into one, two, three, and four levels, and the quality requirements of each level are different.

The acid prices of first -level oil must be less than equal to 0.2 mg/g;

The acid price of secondary oil must be less than equal to 0.3mg/g;

The acid prices of third -level oil must be less than equal to 1.0mg/g;

The acid prices of level 4 oil must be less than equal to 3.0 mg/g.

The lower the acid price, the better the quality. In addition, when buying oil, look at the date of the factory, buy fresh oil as much as possible, and choose small packaging.

Storage

After the large barrel oil is opened, it is regularly poured out of the oil bottle or oil pot in a clean belt. After the large barrel lid is tightened, it is stored in the unseen cabinet to prevent air and water from entering.

Pour the oil bottle or oil pot, try to finish it within one week; the oil in the large barrel should be eaten within three months.

Put the oil bottle or oil pot into the cabinet as much as possible, and do not put it on the window sill or stove.

Oil bottles or oil pots need to be cleaned and used regularly. In addition, the bottle equipped with old oil should not be used directly for new oil, otherwise it may be "infect" and oxidize faster.

Use

Repeated frying of edible oil will not only exceed the prices of acid, but also prone to harmful substances such as benzene, acrylamide, and trans fatty acids. Therefore, it is best not to use edible oil repeatedly.
