Pectin detection

Pectin is a polysaccharide composed of two types: homogeneous polysaccharides and heteropolysaccharides. They are mostly present in the cell walls and inner layers of plants, and are abundant in the peels of citrus, lemon, grapefruit, and other fruits. It is white to yellow powder with a relative molecular weight of approximately 20000 to 400000 and is odorless. Stable in acidic solutions compared to alkaline solutions, it is usually divided into high ester pectin and low ester pectin based on its degree of esterification. The high ester pectin formed a non reversible gel in the range of soluble sugar content ≥ 60%, pH=2.6~3.4. A part of methyl ester of low ester pectin is converted into primary amide, which is not affected by sugar and acid, but needs to combine with divalent ions such as calcium and magnesium to form gel
