(1) The correct order of addition. When multiple flavors are used in combination, the flavor with a lighter flavor should be added first, and then the flavor with a strong flavor should be added.

(2) Choose an appropriate time to add as much as possible during heating and cooling or at the later stage of processing. Foods with added flavors should not be exposed to the air for a long time to avoid loss of flavor by volatilization.

(3) Avoid chemical reactions. The fragrance and diluent in the fragrance are easily oxidized and deteriorated when exposed to air. If microcapsule treatment is used, the oxidation of the fragrance can be avoided as much as possible. Flavor is not stable in alkaline foods. For example, vanillin will lose its aroma after contact with sodium bicarbonate, and the color will become reddish brown.

(4) Mastering the appropriate amount of addition requires accurate weighing. Liquid essence is accurately weighed by gravimetric method. When using, the flavor should be distributed evenly in the food as much as possible.

It can be seen that the use of edible flavors is very particular about methods, otherwise it will only endanger human health. Therefore, if you need to use edible flavors in daily life, you must strictly follow the correct method of use. For the purchase of foods containing edible flavors, it is even more important to go to regular merchants to purchase, and pay attention to the production date.
