NGĀ ĀHUATANGA WHAKAMAHI O TE GELATIN I ROTO I TE REKA NGĀWARI
Te tiakarete Ko te tiēre matua e whakamahia ana hei hanga i ngā monamona pīwariwari nā te mea ka hoatu he kakano pīwariwari kaha ki ngā monamona ngohengohe. I roto i te tukanga hanga monamona ngohengohe, ina whakamataohia te wairewa tiēre ki te 22-25℃, ka totoka te tiēre. E ai ki ōna āhuatanga, ka konatunatua te wairewa tiēre ki roto i te tirikara ka ringihia ki roto i te pokepokea ai i te mea e wera ana. I muri i te whakamatao, ka taea te hanga i tētahi āhua o te tiēre tiēre.
Ko te āhuatanga motuhake o te gelatin ko te kaha ki te huri i te wera. Kei roto i te āhua wairewa te hua kei roto te gelatin ina werahia, ā, ka huri hei āhua tio i muri i te whakamatao. Nā te mea ka taea te whakahoki i tēnei huringa tere i ngā wā maha, kāore ngā āhuatanga taketake o te hua e rerekē. Nō reira, ko te painga nui o te gelatin e whakamahia ana ki te tiēre he tino ngāwari te tukatuka i te wairewa. Ka taea te whakamahana i tētahi hua kua whakakīia mai i te pokepokea paura me te āhua hapa, ka rewa anō ki te 60℃-80℃ i mua i te hanga anō me te kore e pā ki tōna kounga.
Te tiakarete kai iHe pūmua tūturu me ngā rōpū carboxyl me amino ka taea te wehewehe i runga i te mekameka ngota. Nō reira, ki te rerekē te tikanga maimoatanga, ka rerekē te maha o ngā rōpū carboxyl me amino i runga i te mekameka ngota, ka whakatau i te taumata o te pūwāhi isoelectric o te gelatin. Ina tata te uara pH o te monamona tiēre ki te pūwāhi isoelectric o te gelatin, ka ōrite ngā utu pai me ngā utu kino kua wehea mai i te mekameka ngota gelatin, ā, ka iti ake te pumau o te pūmua, ka rite ki te gelatin. Nō reira, e taunakihia ana kia tīpakohia te pūwāhi isoelectric o te gelatin kia matara atu i te uara pH o te hua, nā te mea ko te uara pH o te monamona tiēre gelatin hua kei waenganui i te 3.0-3.6, ko te pūwāhi isoelectric o te kāpia waikawa he teitei ake i te nuinga o te wā, i waenganui i te 7.0-9.5, nō reira ko te kāpia waikawa te mea tino pai.
I tēnei wā, kei te tuku a Gelken i te gelatin kai e tika ana mō te hanga monamona ngohengohe. Ko te kaha o te tiēre he 180-250 bloom. Ko te kaha ake o te tiēre, ko te pai ake o te pakeke me te ngāwari o ngā hua e whakaratohia ana. Ka tīpakohia te matotoru i waenga i te 1.8-4.0Mpa.s i runga i te kaha o te tiēre.
