產品描述

Pectin consists mainly of galacturonic acid and galacturonic acid methyl ester units forming linear

polysaccharide chains, the average molecular weights from about 50, 000 to 150, 000. The

polygalacturonic acid is partly esterified with methyl groups. The ratio of esterified galacturonic acid

groups to total galacturonic acid groups - termed the degree of esterification (de)

Pectin is normally classified according to its degree of esterification: The de of high ester pectin

(hm) is above 50%, and the low ester pectin (lm) is under 50%. These three groups of pectin gel by

different mechanisms.

Hm-pectin require a minimum amount of soluble solids and a pH within a pretty narrow range; Lm-pectin

require the presence of a controlled amount of calcium or other divalent cations for gelation and do not

require sugar and/or acid. The de of hm-pectins controls their relative speed of gelation as reflected

by the designations slow set' and rapid set' high ester pectin. Degree of esterification of lm-pectins

controls their calcium reactivity.

The color of apple pectin powder may vary from yellow-white to light tan. Pectins are normally packed in

vapor tight packaging labeled store cool and dry.
