Pehea e hana ʻia ai ka gelatin?
Hoʻomaka ka hana ʻana o ka gelatin me nā huahana holoholona (nā ʻili, nā iwi, nā ʻiʻo), kahi i hoʻomaʻemaʻe ʻia, hoʻohemo ʻia ka ʻaila, a kuʻi ʻia. ʻO nā ʻili puaʻa (30-50% collagen) a me nā iwi bipi ka mea maʻamau. Ke nānā ʻia nā mea maka e hōʻoia i ka ʻole o nā maʻi a i ʻole nā mea haumia, kahi hana koʻikoʻi no ka gelatin meaʻai/lāʻau lapaʻau.
He aha nā mea e hopohopo ai no ka palekana e pili ana i ka gelatin?
Hiki i ka Gelatin mai nā mea holoholona i hana pono ʻole ʻia ke lawe i nā mea haumia: nā metala kaumaha mai nā wahi ʻoihana, nā antibiotics mai nā holoholona, a i ʻole nā mea maʻi e like me Salmonella. Hoʻāla ka gelatin bipi mai nā wahi endemic BSE i nā hopohopo no ka maʻi prion, ʻoiai ʻo ke kumu kūʻai koʻikoʻi (e laʻa, nā lula EU) e hōʻemi i kēia pilikia. ʻOiai ʻoi aku ka palekana o ka gelatin iʻa, hiki ke loaʻa ka mercury inā loaʻa mai nā wai haumia.
Pehea ka hopena o ka gelatin i ke ʻano o nā huahana meaʻai?
ʻO ka hopena koʻikoʻi o ka Gelatin ka hana ʻana i nā ʻano gel me nā elasticity like ʻole. I loko o nā candies gummy, ʻo ka nui o ka gelatin he 10-15% e hua mai i kahi ʻano chewy a bounce-back. I loko o ka aspic, ʻo nā ʻano haʻahaʻa (2-5%) e hana i kahi gel palupalu a wiliwili e hōʻike ana i nā meaʻai e like me nā mea kanu a i ʻole ka ʻiʻo. ʻO ke kiko heheʻe o ka gel (25-35°C) e hōʻoia i ka palupalu i loko o ka waha, e hoʻonui ana i ka ʻono.
Ka hoʻohana ʻana a me ka nui o ka ʻai ʻana o ka Gelatin
ʻAukake 7 nā ʻike lanpu gelatin
ʻO wau.ʻO ka Gelling a me ka Elasticityʻ
ʻO ka hopena koʻikoʻi o ka Gelatin ka hana ʻana i nā ʻano gel me nā elasticity like ʻole. I loko o nā candies gummy, ʻo ka nui o ka gelatin he 10-15% e hua mai i kahi ʻano chewy, bounce-back. I loko o ka aspic, ʻo nā ʻano haʻahaʻa (2-5%) e hana i kahi gel palupalu a wiliwili e hōʻike ana i nā meaʻai e like me nā mea kanu a i ʻole ka ʻiʻo. ʻO ke kiko heheʻe o ka gel (25-35°C) e hōʻoia i ka palupalu i loko o ka waha, e hoʻonui ana i ka ʻono.
He aha ke kuleana o ka gelatin i ka ʻoihana hoʻonani?
He aha nā hoʻohana o ka gelatin i ka ʻoihana lāʻau lapaʻau?
He aha ka ʻokoʻa ma waena o ka gelatin a me ke collagen?
He aha nā kumu e hoʻopilikia ai i ke kumukūʻai o ka Gelatin?
Pehea e hana ʻia ai ka Gelatin? ʻEhā mau ʻōlelo aʻoaʻo e hoʻololi ai i ka Collagen i Gelatin
He huahana ka Gelatin i loaʻa ma o ka hoʻomaʻemaʻe ʻana a me ka hydrolyzing mua ʻana i ka collagen mai nā ʻili holoholona, nā iwi, a me nā ʻiʻo hoʻohui keʻokeʻo. ʻO nā ʻano hana maʻamau no ka unuhi ʻana i ka gelatin e komo pū me ka alkali, ka waikawa, a me ka mālama ʻana i ka enzyme. Pili ka hana ʻana o ka Gelatin i ʻekolu mau kaʻina hana nui: ka mālama mua ʻana, ka unuhi ʻana o ka gelatin, a me ka mālama ʻana ma hope.
