Hydroxypropyl starch(HPS) naHydroxypropyl methyl cellulose(HPMC) bụ polysaccharides abụọ a na-ejikarị na ngwa ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri na ihe owuwu. N'agbanyeghị myirịta ha, HPS na HPMC nwere ọdịiche dị iche na njirimara anụ ahụ na kemịkal ha, yana ọrụ ha na-arụ. N'ime edemede a, anyị ga-enyocha ọdịiche dị n'etiti HPS na HPMC n'ihe gbasara usoro kemịkalụ, akụrụngwa na ngwa ha.

Ọdịdị Chemical

HPS bụ ihe nrụpụta starch nke a na-enweta site na iji otu hydroxypropyl gbanwee starch eke ekemịkal. A na-ejikọta otu hydroxypropyl na hydroxyl dị iche iche na starch molecule, na-eme ka starch gbanwee ya na nkwụsi ike na nkwụsi ike ka mma. N'aka nke ọzọ, HPMC bụ ihe nrụpụta cellulose nke a na-enweta site n'ịgbanwe cellulose na chemically na hydroxypropyl na methyl otu. A na-ejikọta otu hydroxypropyl na otu hydroxyl na cellulose molecule, ebe otu methyl na-ejikọta na nkeji anhydroglucose.

Njirimara

HPS na HPMC nwere ihe anụ ahụ na kemịkal dị iche iche na-eme ka ha dabara maka ngwa dị iche iche. Njirimara nke HPS gụnyere:

1. Solubility: HPS bụ soluble na mmiri ma nwee ike ịmepụta ngwọta doro anya na obere mkpokọta.
2. Viscosity: HPS nwere viscosity dị ntakịrị ma e jiri ya tụnyere HPMC na polysaccharides ndị ọzọ.
3. Nkwụsi ike: HPS kwụsiri ike na oke okpomọkụ na ọkwa pH ma na-eguzogide ọgwụ enzymes na ihe ndị ọzọ na-emebi emebi.
4. Gelation: HPS nwere ike ịmepụta gels na-agbanwe agbanwe na nnukwu mkpokọta, nke na-eme ka ọ dabara maka nri dị iche iche na ngwa ọgwụ.

Njirimara nke HPMC gụnyere:

1. Solubility: HPMC bụ soluble na mmiri ma mepụta ngwọta doro anya na obere mkpokọta.
2. Viscosity: HPMC nwere viscosity dị elu ma nwee ike mepụta ngwọta viscous ọbụlagodi na obere mkpokọta.
3. Nkwụsi ike: HPMC kwụsiri ike na oke okpomọkụ na ọkwa pH ma na-eguzogide ọgwụ enzymes na ihe ndị ọzọ na-emebi emebi.
4. Ikike imepụta ihe nkiri: HPMC nwere ike imepụta ihe nkiri dị gịrịgịrị, na-agbanwe agbanwe nke bara uru na ngwa ọgwụ na ịchọ mma dị iche iche.

Ngwa

HPS na HPMC nwere ngwa dị iche iche n'ihi njirimara ha dị iche. Ngwa nke HPS gụnyere:

1. Nri: A na-eji HPS dị ka ihe na-agbakọba na ihe nkwụsi ike na ngwaahịa nri dị iche iche, dị ka sos, ofe, na uwe.
2. Ọgwụ: A na-eji HPS dị ka ihe nkedo na nkesa na mbadamba nkume na capsules yana dịka ụgbọ maka nnyefe ọgwụ.
3. Ihe owuwu: A na-eji HPS mee ihe dị ka ihe na-agbakọ na ihe nkedo na ngwaahịa ndị sitere na ciment, dị ka ngwa agha na konkịtị.

Ngwa nke HPMC gụnyere:

1. Nri: A na-eji HPMC dị ka ihe na-esikwu ike na ihe nkwụsi ike na ngwaahịa nri dị iche iche, dị ka ice cream, yogọt, na ngwaahịa esi nri.
2. Ọgwụ: A na-eji HPMC dị ka ihe nkedo, ihe na-agbasasị, na onye na-emepụta ihe nkiri na mbadamba nkume na capsules yana dịka ụgbọ maka nnyefe ọgwụ.
3. Nlekọta onwe onye: A na-eji HPMC na ngwaahịa nlekọta onwe onye dị iche iche, dịka ude mmiri, ncha ntutu, na ihe ịchọ mma, dị ka ihe na-esikwu ike na stabilizer.
4. Ihe owuwu: A na-eji HPMC eme ihe dị ka ihe na-agbakọ na ihe nkedo na ngwaahịa ndị sitere na ciment, dị ka ngwa agha na kọmpat, yana dịka ihe mkpuchi maka ihe owuwu ụlọ.

Mmechi

N'ikpeazụ, HPS na HPMC bụ polysaccharides abụọ a na-ejikarị eme ihe na ngwa ụlọ ọrụ dị iche iche. HPS bụ ihe nrụpụta starch nke nwere obere viscosity dị ntakịrị, na-agbanwe agbanwe nke ọma, ma kwụsie ike n'ọtụtụ ọnọdụ okpomọkụ na ọkwa pH. N'aka nke ọzọ, HPMC bụ ihe mmepụta cellulose nke nwere nnukwu viscosity, nwere ike ịmepụta ihe nkiri dị gịrịgịrị, na-agbanwe agbanwe, ma kwụsie ike n'ọtụtụ okpomọkụ na ọkwa pH. Esemokwu dị n'etiti ogige abụọ a na-eme ka ha dị mma maka ngwa dị iche iche na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, nlekọta onwe onye, ​​na ihe owuwu.
