Hydroxypropyl starch ether-HPS

Okwu Mmalite maka Starch

Starch bụ otu n'ime carbohydrates kachasị baa ụba a na-ahụ n'okike ma na-eje ozi dị ka isi iyi ike maka ọtụtụ ihe dị ndụ, gụnyere ụmụ mmadụ. Ọ mejupụtara otu glucose ejikọtara ọnụ n'usoro ogologo, na-emepụta amylose na amylopectin molecules. A na-esikarị na osisi dịka ọka, wit, nduku, na osikapa ewepụta molecules ndị a.

Mgbanwe Starch

Iji mee ka ihe ndị dị na ya ka mma ma gbasaa ojiji ya, starch nwere ike ịgbanwe ọtụtụ ihe dị iche iche na kemịkalụ. Otu n'ime mgbanwe ndị a bụ iwebata otu hydroxypropyl, nke na-ebute hydroxypropyl starch ether (HPS). Mgbanwe a na-agbanwe njirimara anụ ahụ na kemịkalụ nke starch, na-eme ka ọ dịkwuo mfe ma dabara adaba maka ọtụtụ ojiji ụlọ ọrụ.
