Nā ʻano noi o ka gelatin i loko o ke kō palupalu
Gelatin ʻO ia ka gel mua i hoʻohana ʻia e hana i nā kinikini gummy elastic no ka mea hāʻawi ia i nā kinikini palupalu i kahi ʻano elastic ikaika loa. I ke kaʻina hana o ka hana ʻana i nā kinikini palupalu, ke hoʻomaʻalili ʻia ka hopena gelatin i 22-25 ℃, lilo ka gelatin i mea paʻa. Wahi a kona mau ʻano, ua hui ʻia ka hopena gelatin i loko o ka syrup a ninini ʻia i loko o ka ʻōmole i ka wā e wela ana. Ma hope o ka hoʻomaʻalili ʻana, hiki ke hana ʻia kekahi ʻano o ka jelly gelatin.
ʻO ke ʻano hoʻohana kūikawā o ka gelatin, ʻo ia ka hiki ke hoʻohuli i ka wela. Aia ka huahana i loaʻa ka gelatin i loko o kahi kūlana hoʻonā i ka wā e hoʻomehana ʻia ai, a lilo i kūlana hau ma hope o ka hoʻomaʻalili ʻana. No ka mea hiki ke hana hou ʻia kēia hoʻololi wikiwiki i nā manawa he nui, ʻaʻole loli iki nā ʻano kumu o ka huahana. ʻO ka hopena, ʻo ka pōmaikaʻi nui o ka gelatine i hoʻopili ʻia i ka candy jelly, ʻo ia ka maʻalahi loa o ka mālama ʻana i ka hopena. Hiki ke hoʻomehana ʻia a hoʻoheheʻe hou ʻia kekahi huahana gelled mai ka ʻōmole pauka me kekahi ʻano hemahema i 60 ℃-80 ℃ ma mua o ka hoʻoheheʻe hou ʻana me ka ʻole o ka hoʻopilikia ʻana i kona ʻano.
Gelatin papa meaʻai ihe protein kūlohelohe me nā hui carboxyl a me nā amino dissociable ma ke kaulahao molekala. No laila, inā ʻokoʻa ke ʻano hana, e loli ka helu o nā hui carboxyl a me nā amino ma ke kaulahao molekala, ka mea e hoʻoholo ai i ka pae o ke kiko isoelectric o ka gelatin. Ke kokoke ka waiwai pH o ka candy jelly i ke kiko isoelectric o ka gelatin, ua like nā uku maikaʻi a me nā uku maikaʻi ʻole i hoʻokaʻawale ʻia mai ke kaulahao molekala gelatin, a lilo ka protein i mea paʻa ʻole a gelatinous. No laila, ua ʻōlelo ʻia e koho ʻia ke kiko isoelectric o ka gelatin mai ka waiwai pH o ka huahana, no ka mea, ʻo ka waiwai pH o ka candy jelly gelatin huaʻai ma waena o 3.0-3.6, ʻoiai ʻoi aku ka kiʻekiʻe o ke kiko isoelectric o ka glue acid, ma waena o 7.0-9.5, no laila ʻo ka glue acid ka mea kūpono loa.
I kēia manawa, hoʻolako ʻo Gelken i ka gelatin hiki ke ʻai ʻia i kūpono no ka hana ʻana i nā kini palupalu. ʻO ka ikaika o ka jelly he 180-250 bloom. ʻO ke kiʻekiʻe o ka ikaika o ka jelly, ʻoi aku ka maikaʻi o ka paʻakikī a me ka elasticity o nā huahana i hāʻawi ʻia. Koho ʻia ka viscosity ma waena o 1.8-4.0Mpa.s e like me ka ikaika o ka jelly.
