discovery that some HMPs contain a mixture of a calcium- 1
sensitive fraction (CSP) and a non-calcium sensitive fraction
(NCSP) which can be separated into separate fractions in a
commercially feasible manner. Thus, pectin which has a high
degree of esterification wherein its few reactive carboxylic
acid units are evenly distributed along the chain as depicted
in schematic Formula III, is said to be relatively unreactive
to calcium ions and other metal cations, and is referred to as
a NCSP fraction pectin. In contrast, an
