Pectin is a polymeric carbohydrate, which is a natural component of the cell wall and the middle lamella in all green land plants. Hence, it has an important influence on the structural properties of fruits and vegetables.
Commercial pectins are white, light yellow or yellow powder without odour.
Generally, pectin is a linear polysaccharide chain which consists mainly of galacturonic acid units. The galacturonic acid molecules can be esterified with methanol. According to the degree of esterification (DE), pectin is classified into high methoxyl pectin (HM) with a degree of esterification higher than 50% and low methoxyl pectin with a degree of esterification less than 50% (LM).
