Hydroxypropyl starch ether-HPS

Okwu Mmalite na Starch

Starch bụ otu n'ime carbohydrates kachasị ukwuu a na-achọta na okike ma na-eje ozi dị ka isi iyi ike maka ọtụtụ ihe ndị dị ndụ, gụnyere mmadụ. Ọ mejupụtara nkeji glucose jikọtara ọnụ na agbụ ogologo, na-akpụ amylose na amylopectin molecules. A na-ewepụtakarị mkpụrụ ndụ ndị a site na osisi ndị dị ka ọka, ọka wit, poteto, na osikapa.

Mgbanwe starch

Iji welie akụrụngwa ya na ịgbasa ngwa ya, starch nwere ike ime mgbanwe kemịkalụ dị iche iche. Otu mgbanwe dị otú ahụ bụ iwebata otu hydroxypropyl, na-ebute hydroxypropyl starch ether (HPS). Ngbanwe a na-agbanwe njirimara anụ ahụ na kemịkalụ nke starch, na-eme ka ọ dịkwuo mfe ma dabara maka ọtụtụ ọrụ mmepụta ihe.
