Coating a layer of film on the surface of some foods not only looks bright and beautiful, but also adjusts the breath and prolongs the shelf life. These substances used for food appearance, shelf life, preservation, glazing, prevention of mold erosion and water evaporation are called coating agents.
Food coatings are used in many of our dishes.
Preparing food with a coating thereon is not only used to maintain the texture, mouthfeel, and taste of the food during the cooking process, but also to provide crispness and additional flavor to the coated food. Typical examples of such coated foods are chicken, fish, meat, shrimp and vegetables. The types of these coatings range from very thick and opaque coatings (such as bread coating on fried breaded shrimp) to light and relatively transparent coatings (such as egg and milk coating on vegetables). Although such coated foods can be cooked by grilling, baking and frying, most of these coated foods are intended to be cooked by frying (especially oil frying or deep oil frying), such as deep-frying Chicken, tempura (such as vegetables and seafood), shrimp and French meat.
While these coatings make the food more delicious, it also keeps the food longer. It is a very useful invention.
Food coatings can be seen everywhere.
The most common coatings are wax coatings for fruits, lipid films for protecting meat products and chocolate coatings for a range of foods. Edible coatings have failed regulations in different countries. In the United States, edible coatings are classified as "Generally Recognized as Safe" established by the "US Food Safety Administration". The edible film can be cellulose ether, starch, hydroxypropyl starch, zein, wheat gluten, soy protein and milk protein. Food processing companies considering the use of protein-based films should note that many consumers are intolerant to wheat gluten and are allergic to milk protein.
Polishing agent is a food coating agent.
Polishes in food and beverage applications mainly have coating capabilities, film-forming properties and adhesion capabilities, and have a polished appetizing visual appeal. Polishing agents are used in the confectionery industry. Polishing agents are used as coatings in hard candies and various other types of candies. Glazing agent is also used in certain baked goods, such as doughnuts and other bread foods.
Food coatings have many uses.
Film-coated fruit can inhibit water evaporation and prevent microbes from invading and forming an atmosphere, which may extend the time of fresh fruit. Some candies, such as chocolate, not only look bright and beautiful on the back of the film, but also prevent adhesion and maintain a stable quality. Recently, we have added certain preservatives and antioxidants to make complex preservatives.
Commonly used reagents are natural beeswax, paraffin wax, shellac and so on. In addition, there are some synthetic products, such as morpholine fatty acid salts.
Coating agents can be divided into spraying type and coating type. The agent is polystyrene, paraffin wax, beeswax, sodium oleate, shellac preparation, ethylene oxide, higher fatty alcohol, fatty acid salt of morpholine, magnesium silicate, vinyl acetate resin and so on. Coating agents include glutinous rice, clothing, wax-impregnated paper, polyvinyl acetate, etc. You can browse our website page for more information about food coatings.
There are several varieties of food coating agents, including microcrystalline wax, paraffin wax and white oil
