Pectin is a kind of polysaccharide, and its composition includes two types of homopolysaccharide and heteropolysaccharide. They mostly exist in the cell wall and an inner layer of plants, and they are mostly found in citrus, lemon, grapefruit, and other peels. White to yellow powder, relative molecular weight is about 20000 ~ 400,000, and tasteless. It is more stable in acidic solution than in alkaline solution and is usually divided into high ester pectin and low ester pectin according to its degree of esterification. High ester pectin forms an irreversible gel in the range of soluble sugar content ≥60% and pH = 2.6 ～ 3.4. Part of the methyl ester of low-ester pectin is converted into a primary amide, which is not affected by sugar and acid, but it needs to combine with divalent ions such as calcium and magnesium to form a gel.
Maltodextrin is a low conversion product of starch, whose molar mass is between starch and starch sugar. Its raw materials are starchy corn, rice, etc., and it can also be refined starch, such as corn starch, wheat starch, cassava starch, and the like. The main component is dextrin and contains polysaccharides, tetrasaccharides or oligosaccharides with more than tetrasaccharides, and also contains a small amount of maltose and glucose.
In recent days, Foodchem made great effort to find resources and accumulated a batch of protective mask resources. In order to help all friends who care and support Foodchem to better protect themselves against the new coronavirus, Foodchem has made a small contribution by sending a batch of protective masks to those who need them. Together, we will fight against the new coronavirus, look forward to the end of the epidemic, and enjoy the wonderful world again.
People receiving packages from China are not at risk of contracting the new coronavirus. From previous analysis, we know coronaviruses do not survive long on objects, such as letters or packages.
The three-day Ingredients Russia 2020 in Moscow is ended on February 20, and Foodchem Group attended this exhibition for the 12th consecutive year.
