Storage and preservation of seasonings
(1) Physical and chemical properties Seasonings include animal, plant, chemically synthesized, and mineral seasonings. Their physical and chemical properties mainly include volatility, deliquesce, corrosiveness, oxidizability, and evaporation.
(2) Requirements for containers According to the physical and chemical properties of seasonings, the requirements for containers are that they have a certain degree of heat resistance and have certain functions of preventing deliquesce, volatilization, and evaporation.
(3) Storage precautions
1) Control the ambient temperature If the temperature is too high, liquid seasonings will become corrupt and deteriorate, and oxidatively decompose. For example, vinegar, soy sauce, cooking wine, and cooking oil are prone to deterioration at high temperatures. If the temperature is too low, the tissue structure of fresh plant seasonings, such as ginger and garlic, will be destroyed, causing water loss and affecting the quality of the seasoning.
2) Control the ambient temperature If the ambient temperature is too high, solid powdered seasonings will become damp or even moldy. For example, sugar, turmeric powder, pepper powder, monosodium glutamate, starch, etc. are prone to dampness and mold in a high temperature environment. Too low a temperature will cause the water in some vegetable seasonings to evaporate, such as coriander, ginger, garlic, etc., which are easy to wilt and shrink.
3) Keep away from light. Seasonings such as oils and fats will deteriorate if exposed to strong light for a long time. They should be stored in a dark place.
4) Keep the seasonings airtight. Some seasonings must be sealed. If the sealing conditions are not good, they will lose their seasoning properties.
5) Prevent contamination between seasonings. Seasonings should be stored in different categories. Keep them clean during use.
(4) Principles of seasoning storage and preservation
1) Put them in first and use them in time.
2) Store them separately for different properties.
3) Use them sparingly and reduce waste.
