Hydroxypropyl starch(HPS) aHydroxypropyl methyl cellulose(HPMC) ʻelua polysaccharides i hoʻohana mau ʻia i nā noi ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ke kūkulu ʻana. ʻOiai ko lākou ʻano like, loaʻa nā ʻokoʻa like ʻole o ka HPS a me ka HPMC i kā lākou mau waiwai kino a me nā waiwai kemika, a me kā lākou mau kuleana hana. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o HPS a me HPMC e pili ana i kā lākou ʻano kemika, waiwai, a me nā noi.

Hoʻolālā Kimia

ʻO ka HPS kahi hua maloʻo maloʻo i loaʻa ma ka hoʻololi ʻana i ka starch maoli me nā hui hydroxypropyl. Hoʻopili ʻia nā pūʻulu hydroxypropyl i nā pūʻulu hydroxyl ma ka mole starch, e hopena i kahi starch i hoʻololi ʻia me ka hoʻomaikaʻi ʻana a me ka paʻa. ʻO HPMC, ma ka ʻaoʻao ʻē aʻe, he cellulose derivative i loaʻa ma ka hoʻololi kemika cellulose me nā hui hydroxypropyl a me methyl. Hoʻopili ʻia nā pūʻulu hydroxypropyl i nā pūʻulu hydroxyl ma ka mole cellulose, aʻo nā hui methyl e pili ana i nā ʻāpana anhydroglucose.

Waiwai

Loaʻa i ka HPS a me ka HPMC nā waiwai kino a me nā kemika e kūpono ai no nā noi like ʻole. Aia nā waiwai o HPS:

1. Solubility: Hiki ke hoʻoheheʻe ʻia ka HPS i ka wai a hiki ke hana i nā hāʻina maʻemaʻe ma nā haʻahaʻa haʻahaʻa.
2. Viscosity: He haʻahaʻa ko HPS i hoʻohālikelike ʻia me HPMC a me nā polysaccharides ʻē aʻe.
3. Paʻa Paʻa: Paʻa ka HPS ma kahi ākea o nā wela a me nā pae pH a kūpaʻa i nā enzymes a me nā mea hoʻohaʻahaʻa ʻē aʻe.
4. ʻO Gelation: Hiki i ka HPS ke hana i nā gels hiki ke hoʻohuli ʻia i ka wela i nā kiʻekiʻe kiʻekiʻe, e kūpono ai ia no nā meaʻai like ʻole a me nā noi lāʻau.

Aia nā waiwai o HPMC:

1. Hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia ka HPMC i ka wai a hana i nā hāʻina maʻemaʻe ma nā haʻahaʻa haʻahaʻa.
2. Viscosity: Loaʻa i ka HPMC kahi viscosity kiʻekiʻe a hiki ke hana i nā hāʻina viscous ʻoiai ma nā haʻahaʻa haʻahaʻa.
3. Paʻa Paʻa: Paʻa ka HPMC ma kahi ākea o nā wela a me nā pae pH a kūpaʻa i nā enzymes a me nā mea hoʻohaʻahaʻa ʻē aʻe.
4. Hiki ke hana kiʻiʻoniʻoni: Hiki i ka HPMC ke hana i nā kiʻiʻoniʻoni lahilahi a hiki ke hoʻohana ʻia i nā ʻano lāʻau lapaʻau a me nā mea hoʻonaninani.

Nā noi

Loaʻa nā noi like ʻole o HPS a me HPMC ma muli o ko lākou mau waiwai ʻokoʻa. Aia nā noi o HPS:

1. Meaʻai: Hoʻohana ʻia ʻo HPS ma ke ʻano he mānoanoa a hoʻopaʻa i nā huahana meaʻai like ʻole, e like me nā kīʻaha, nā sopa, a me nā lole.
2. Pharmaceutical: Hoʻohana ʻia ʻo HPS ma ke ʻano he mea hoʻopaʻa a hoʻopau i nā papa a me nā capsules a ma ke ʻano he kaʻa no ka lawe ʻana i ka lāʻau.
3. Hana ʻia: Hoʻohana ʻia ʻo HPS ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa i nā huahana sima, e like me ka mortar a me ka pahu.

Aia nā noi o HPMC:

1. Meaʻai: Hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa a hoʻopaʻa i nā huahana meaʻai like ʻole, e like me ka ice cream, yogurt, a me nā mea i kālua ʻia.
2. Pharmaceutical: Hoʻohana ʻia ʻo HPMC ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka mea hana kiʻiʻoniʻoni i nā papa a me nā capsules a ma ke ʻano he kaʻa no ka lawe ʻana i ka lāʻau.
3. Mālama Pilikino: Hoʻohana ʻia ʻo HPMC i nā huahana mālama pilikino like ʻole, e like me nā lotion, shampoos, a me nā mea hoʻonaninani, ma ke ʻano he mānoanoa a me ka stabilizer.
4. Hana ʻia: Hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa i loko o nā huahana sima, e like me ka mortar a me ke kaʻa, a ma ke ʻano he mea uhi no nā mea kūkulu hale.

Ka hopena

I ka hopena, ʻo HPS a me HPMC ʻelua polysaccharides i hoʻohana nui ʻia i nā noi ʻoihana like ʻole. ʻO ka HPS kahi mea hoʻoheheʻe starch me ka haʻahaʻa haʻahaʻa, hiki ke hoʻohuli i ka wela, a paʻa i ka laulā o nā wela a me nā pae pH. ʻO ka HPMC, ma ka ʻaoʻao ʻē aʻe, he cellulose derivative i loaʻa ka viscosity kiʻekiʻe, hiki ke hana i nā kiʻi ʻoniʻoni lahilahi, hiki ke maʻalahi, a paʻa hoʻi i kahi ākea o nā wela a me nā pae pH. ʻO nā ʻokoʻa ma waena o kēia mau pūhui ʻelua e kūpono iā lākou no nā noi like ʻole i nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, mālama pilikino, a me ke kūkulu ʻana.
