The harm of adding salt to cooking oil

Every family has different methods and theories when cooking. Some people think that salt must be added after the dishes are out of the pot to avoid serious damage to the nutritional value. But some people think that adding salt to the oil when cooking can prevent the oil from spraying out. At the same time, it can also make the salt dissolve quickly and make the dishes evenly flavored. Let us learn about the order of adding salt when cooking.

1. Our salt contains iodine compounds. If you add salt before cooking, it is likely to cause them to evaporate. Long-term iodine deficiency can easily lead to goiter.

2. Adding salt first will hinder the full expansion of the raw material cells and affect the crispness and tenderness of the dish. This is due to osmotic pressure, it will "wilt".

Special attention should be paid, but it is not advisable to add salt after cooking with peanut oil, because peanuts are easily contaminated by yellow mold, which will produce a toxin if the conditions are right. When stir-frying, add some salt after the oil is hot, and then add seasonings and vegetables after half a minute to a minute. The iodide in the salt can remove the aflatoxin.

In addition, it is advisable to add salt before adding the vegetables when cooking with animal oil. This can reduce the residual amount of organochlorine in animal oil and is beneficial to human health.

When is the best time to add salt when cooking?

When to add salt when cooking should be determined according to different dishes. Different foods have different cooking methods. Some dishes are better added with salt before cooking, some are good for the body when adding salt during the cooking process, and some dishes are better added with salt before being fried. Therefore, when cooking, we should decide when to add salt according to the dishes, rather than generalizing.

Add salt before cooking

If you use lard, chicken fat, peanut oil that does not reach the level of carefully selected peanuts to cook, you should add a small amount of salt to the oil before cooking.

Reason: Adding a small amount of salt before cooking can help eliminate the residual amount of organochlorine pesticides in animal oil. The iodide in the salt can also remove the extremely small amount of aflatoxin present in peanut oil that is not completely selected from peanuts. When cooking with these oils, add a small amount of salt first, which is good for human health.

Add salt during cooking

When cooking meat dishes, including fish, meat, shrimp, etc., you can add a small amount of salt while frying, but at this time it mainly serves as a seasoning and is used to enhance the flavor.

Reason: Because salt can combine with amino acids to form sodium amino acid salt, which is the component of MSG, making the food taste delicious. But you must remember that the amount of salt you put in must be small, just enough to add the finishing touch, otherwise too much salt will make the meat poor in quality. Add the remaining salt before serving, so that the dish will have both a mature and fresh taste.
