Decryption: Why Does Fried Food Or Vegetable Oil Smell Like Saliva?
Time:Fri-04-22 hits:
The fried food on the table will not be crispy and crispy after a night, and it will taste moist.
The processed sunflower seeds and nut foods on the table are some of the small snacks we eat every day. But when left for a night or two, there will be a smell of saliva.
Often when we eat food with this taste, our hearts will resist. But why exactly?
This phenomenon is the deterioration of oil, which can also be called oil rancidity.
Acid value is an indicator to measure the degree of rancidity of oil.
The higher the acid value, the worse the quality of the oil; the lower the acid value, the better the quality of the oil and the fresher it is.
There are many reasons for the rancidity of cooking oil:
1. The seal is not tight
2. Sun exposure
3. Exposure to air
Rancidity can also be divided into two categories: oxidative rancidity and hydrolytic rancidity.
Oxidative rancidity: Peroxides are produced, which continue to decompose to form aldehydes and ketones and other oxides, further depreciating oily foods.
Hydrolytic rancidity: Free fatty acid will be produced, and free fatty acid will accelerate the rancidity of fat, so the rancidity caused by this free fatty acid is measured by acid value.
What are the effects of rancid cooking oil on the human body?
1. The nutritional value will be reduced.
2. Aldehydes, ketones, and acids produced during rancidity will destroy fatty vitamins, causing gastrointestinal discomfort, diarrhea, and damage to the liver.
3. The free radicals generated in the process of rancidity can also lead to human aging, tumors, and cardiovascular diseases.
Therefore, fried foods should be eaten as soon as possible. If you haven't finished eating, try to put it into a well-sealed crisper to avoid contact with air and moisture.
