Introduction:
Amylopectin is a glucose-based, highly-branched polysaccharide which together with amylose makes starch. The glucosidic bonds of amylopectin are �±-1,4 in the glucan chain and �±-1,6 at the branch points. Amylopectin from maize differs in structure form amylopectin from other plant species and is used in the study of the development of starches.
Immune-modulating glucan with reported potential in immunotherapy of chronic hepatitis, diseases of the digestive and respiratory systems, anti-tumor activity for breast, cervical, liver and uterine cancers.

Application:
Amylopectin is the most common carbohydrate in the human diet and is contained in many staple foods. The major sources of amylopectin of starch intake worldwide are the cereals such as rice, wheat, and maize, and the root vegetables potatoes and cassava. Upon cooking, amylopectin in the starch is transformed into readily accessible glucose chains with very different nutritional and functional properties. During cooking with high heat, sugars released from amylopectin can react with amino acids via the Maillard reaction, forming advanced glycation end-products (AGEs), contributing aromas, flavors and texture to foods.

The amylose/amylopectin ratio, molecular weight and molecular fine structure influences the physicochemical properties as well as energy release of different types of starches,which affects the number of calories people consume from food. Amylopectin is also sometimes used as a workout supplement due to this caloric density and a correlation with muscle protein synthesis

Introduction&Application:

Celite is due to its unique physicochemical properties, has been widely used as a filter aid, functional filler, catalyst carrier, pesticide and fertilizer carrier, insulation material, adsorbent, and bleaching material. Diatomaceous earth is used as a filter aid in the food industry due to its strong adsorption capacity, which plays a role in removing bacteria, impurities, and odors. If diatomaceous earth is used for filtration during the brewing process, the filter bed can be continuously updated, with fast filtration speed and high yield; With a large surface area and strong adsorption capacity, it can filter out particles ranging from 0.1 to 1.0 �¼ m, reduce alcohol loss by about 1.4%, and improve production operating conditions. Diatomaceous earth filters can better improve the water quality of circulating water treatment effluent in swimming pools, and can save water and electricity in the operation and management of swimming pools. Secondly, diatomaceous earth has also been widely used in edible oils, pharmaceutical oral liquids, and other fields. Diatomaceous earth is widely used in wastewater treatment due to its stable chemical properties, strong adsorption capacity, good filtration performance, and insolubility in any strong acid. The use of diatomaceous earth flocculation precipitation method for pre-treatment of landfill leachate can preliminarily reduce CODCr and BOD5 in the leachate, remove pollutants such as SS, improve its biochemical properties, reduce load, and create favorable conditions for the normal operation of subsequent biochemical treatment. Diatomaceous earth can be made into interior wall coatings, characterized by non reflective walls and soft indoor lighting. Japanese people refer to wallpaper coated with diatomaceous earth as "breathable walls.".
