Seasonings are generally processed products that are acidic or alkaline. Therefore, if they are placed in metal utensils for a long time, they will easily corrode the metal and cause the flavor of the seasonings to change. Although the seasonings in stainless steel containers are durable, they are prone to electrolyte reaction and the material will fall off if they are stored for a long time with strong corrosive objects such as acids and alkalis. This shed material is mixed into the seasoning and enters the human body, which is easy to cause damage to the human liver, and in serious cases, there is even a risk of liver cancer.
Some families like to use beverage bottles or mineral water bottles for oil, salt, sauce and vinegar, which is actually worse. The main raw material for making beverage bottles is polypropylene plastic, which is non-toxic and harmless. It is used to hold soda and cola-type beverages without adverse effects on the human body; but because plastic bottles still contain a small amount of vinyl monomer, if the fat-soluble alcohol, vinegar, etc. is stored for a long time Organic matter will undergo a chemical reaction. Long-term consumption of ethylene-contaminated food can cause dizziness, headache, nausea, loss of appetite, and memory loss. In severe cases, it can also lead to anemia.
To see if there is glaze in the ceramic bottle seasoning
Since ceramic ware has no metal components, sauces, etc. will not chemically react with it, so it is a suitable container for condiments. But at present, some ceramic utensils have the habit of glazing, so when choosing ceramic products, try to choose ceramics without glaze, because some glazes may have metal exceeding the standard. That is to say, when purchasing, try to choose ceramics with colorful or many patterns as little as possible, and try to choose ceramic ware with a clean background color.
For sauces and other condiments, the most suitable one should be glassware. Because glassware is stable in nature, chemical reactions are not prone to occur, and the quality of the seasoning will not be affected.
Dry condiments should be waterproof and edible oil to avoid high temperature
Mentioned earlier are condiments such as soy sauce, salt, etc., which are directly used for cooking. For dried products such as star anise, the most important thing is to create a dry environment. After buying it, it should be packed in a sealed container and stored in a dry environment.
Because the oxidation reaction of oil will be very fast at high temperatures, remember not to put the cooking oil directly next to the stove. Although it is very convenient, the high temperature of the stove can easily cause the cooking oil to deteriorate. The same is true for sauces containing fat and oil, such as soy sauce.
