"Quilted agent" sounds like a strange, awkward word. In fact, you have seen it, apples, oranges and other fruits stored for a week or tender, crisp, because there is a natural film agent - fruit wax protection, both inhibit the evaporation of water, but also to prevent the invasion of microorganisms; the appearance of candy and chocolate is dressed up with synthetic film agent, both beautiful and independent, and delicious soul.

What is the coating agent

The coating agent is a substance that can form a film after being applied to the surface of the food, which can prevent the invasion of microorganisms and form a modified atmosphere layer, inhibit the evaporation of water, play a role in preserving quality and freshness, and also make the appearance of food bright and beautiful.

The people summed up experience from life, using glutinous rice starch paper as the coating agent for candy, and using konjac extract powder, cocoa butter, coconut oil, etc. as the coating agent for fruits. The film agents approved for use in China's "National Standards for Food Safety and Food Additives Use Standards" include naturally derived beeswax, carnauba wax, lac (shellac), stearic acid, prolanpolysaccharide, morpholine fatty acid salts (fruit wax), as well as chemical modification and pure chemical synthetic sources of white oil (liquid paraffin), rosin pentaerythritol ester, dimethicone and its emulsion, polyethylene glycol, polyvinyl alcohol.

Applied by film agent

Fruit and vegetable preservation coating film Fruits and vegetables will still be respiration after picking, and when oxygen is sufficient, it will consume the organic components in the body and accelerate the aging of fruits and vegetables; when oxygen is lacking, it will undergo anaerobic respiration, forming incomplete oxides such as ethanol, so that fruits and vegetables form physiological diseases. Fruit and vegetable coating film preservation can form a permeable film with moderate oxygen and carbon dioxide on the surface of fruits and vegetables, forming a small environment that moderately restricts oxygen supply, delays the aging process of fruits and vegetables, reduces water evaporation, and forms a film that can also prevent microbial invasion.

Food preservation In the storage process of grain, the coating agent can effectively isolate germs and insect pests, and can also inhibit the respiration of grain to a certain extent; used for frozen food, which can prevent the product quality from deteriorating due to surface moisture absorption; the coating film preservation of egg food can prevent microbial invasion, prevent the evaporation of water in the egg, and reduce spoilage.

Anti-stick and polishing coating Film In the production of cakes such as biscuits and bread, the coating film of baking molds in advance can facilitate the release of products and maintain the appearance of products perfectly. Some candies such as chocolate and other surface coatings, the appearance of bright, beautiful, but also to prevent moisture caused by adhesions.

Ideal for coating agents

To eliminate the harm that food additives such as film agents may cause to the human body, it is necessary for production enterprises to choose safe formulas in the food production process and strictly comply with the standards for the use of food additives.

The ideal coating agent should be easy to coat, easy to form a film, and the formation of a uniform, continuous, with good quality preservation effect, the most important thing is non-toxic, no odor, and food contact will not produce harmful substances to the human body. The membrane agent approved by the state can meet such requirements.
