Coating agent refers to the substance applied to the appearance of food  (Thailand food Ingredient supplier) , such as quality preservation, fresh-keeping  (Thailand food flavour wholesale) , glazing, preventing water evaporation and so on. According to the solubility  (Thailand food flavour supplier) , it can be divided into water-insoluble and water-soluble film agents. The films listed in National food standard have been evaluated for safety, so their use in accordance with the regulations will not cause harm to the human body. These coating agents are mainly used in fruits, vegetables, fudge, eggs and other food fresh-keeping. Among them, carnauba wax has established ADI value, shellac, food grade mineral oil, stearic acid and beeswax are recognized as general safe substances with unspecified ADI value.

Because mineral oil is not absorbed and digested in human intestine and hinders water absorption, large intake can lead to diarrhea and affect the absorption of fat-soluble vitamins, calcium and phosphorus, therefore, the food-grade mineral oil (white oil) in the film is only allowed to be used as a fresh-keeping film for eggs and gel candies in China  (Thailand food Ingredient supplier) . Fruit wax is used for fruit preservation, only for coating, but not for direct consumption.
