Food coating agents are usually used to wax fruits and package foods. It is a very common food additive. We provide the following three food coating agents. Let us learn more about them.
Microcrystalline wax has a wide range of applications in food and medicine.
Microcrystalline wax has a higher molecular weight and a higher viscosity when melted. It has a very fine-grained crystalline structure in the solid state. Microcrystalline wax with lower melting strength has toughness, elasticity and dryness, and forms a stronger heat seal than pure paraffin wax. Moreover, these waxes do not have a clear and definite transition point in the solid state, and they have the characteristics of a wider range of melting/solidification strength than paraffin wax. These advantages make microcrystalline wax more suitable for the food industry.
Therefore, in the food industry, food coatings made of this microcrystalline wax are mainly used for chewing gum components, food coatings (that is, for cheese coatings for preservation), fruit coatings, beverage coatings, milk cartons , Meat and poultry coatings, bread wrappers, paper containers (such as cartons for ice cream, milk and juice), and linings for cans.
The food additive paraffin wax is obtained from oily wax as raw material, after sweating or solvent de-oiling, and then hydrofining or clay refining.
Paraffin wax can be divided into food grade and industrial grade. Food grade is commonly known as artificial wax. Industrial grade industrial paraffin is inedible. In fact, it is normal to wax apples. There are many special waxing factories. Waxing is to keep the fruit fresh and make the fruit look brighter. my country has regulations for fruit waxing. According to the "Sanitary Standards for the Use of Food Additives", waxing of the surface of fresh fruits is allowed, but the specified additives must be used and appropriate amounts added as needed.
Edible wax is divided into natural wax and artificial wax. Natural wax is a kind of wax film formed by the fruit itself to prevent external microorganisms and pesticides from invading the pulp. This is why the fruit can keep fresh for a certain period of time. Generally speaking, it cannot be scraped out. There is also artificial wax, which is a fatty compound synthesized from high fatty alcohol and high fatty acid. This wax enters the human body and cannot be absorbed. If you want to remove the edible wax on the surface of the fruit before eating, scald it with hot water and then wash it off.
Food-grade white oil is widely used in food glazing, anti-sticking, defoaming, planning and sealing. It can be used as a coating agent for macaroni, bread, biscuits, chocolate and other foods. It can extend wine, vinegar, fruit, Storage and preservation period of vegetables and canned food. In terms of performance, food-grade white oil has good yellowing resistance, oxidation resistance and good viscosity-temperature performance. It is suitable for the lubrication of processing equipment in the food industries such as grain and oil processing, fruit and vegetable processing, dairy product processing, and bread cutting machines.
With the continuous improvement of industry requirements, relevant product regulations, and food safety laws and regulations, the use of food-grade white mineral oil is showing a growing trend. It uses mineral oil obtained after deep refining of hydrogenated raw materials. Our food coating agent-food-grade white oil has undergone two and three hydrogenation treatments in the production process, and its heavy metal content and arsenic content have reached the relevant national food-grade white oil standards and passed national certification.
Food-grade white oil is a product used in many industries such as food processing, cosmetics, and pharmaceutical industries, and its development prospects are unlimited.
Pneumatic pouring test machine is a new pouring equipment used in the development of laboratory confectionery. The working power of the machine is compressed air, and the whole working environment is hygienic and clean, which meets the production requirements of food hygiene. The machine is controlled by human pneumatic, touch screen operation, compact structure, stable performance. It is an ideal experimental equipment for pouring gelatin, pectin and carrageenan gummy candies.
