Kapia Gellan Kaihanga Newgreen Gellan gum Tāpiritanga
Whakaahuatanga Hua
Ko Gellan Gum, e mohiotia ana ko Keke glue, Jie cold glue ranei, he mea tito tuatahi ki te hukahuka, te waikawa glucuronic, me te rhamnose i roto i te ōwehenga o te 2:1:1. He polysaccharide raina e wha nga monosaccharides hei wae hanganga tukurua. I roto i tona hanganga acetyl teitei o te taiao, kei reira nga roopu acetyl me te waikawa glycuronic, kei runga i te waeine hukahuka kotahi. I te toharite, kei ia waeine tukurua kotahi te roopu waikawa glycuronic, kei ia waeine tukurua kotahi te roopu acetyl. I runga i te saponification ki te KOH, ka huri ki te iti acetyl matao whakapiri. Ka taea te whakakore i nga roopu waikawa glucuronic e te pāhare pāporo, te konutai, te konupūmā, me te tote konupora. He iti ano te hauota ka puta i te wa o te FERMENTATION.

Mahi
Ka taea te whakamahi i te kapia Gellan hei whakamaroke me te whakapumau.
He reka te hua o te ra, he pai te tukunga o te kakara, ka rewa ki to waha.
He pai te pumau, te aukati waikawa, te aukati enzymolysis. Ko te reera i hangaia he tino pumau ahakoa i raro i nga tikanga o te tunu kai me te tunu kai, he tino pumau ano hoki i roto i nga hua waikawa, a he pai te mahi i raro i nga tikanga o te uara pH 4.0 ~ 7.5. Ko te kakano kaore e pa ki te waa me te pāmahana i te wa e rokiroki ana.
Taupānga
Ka taea te whakamahi i te whakapiri matao hei whakakaha me te whakapumau. Whakatupato Whakamahi: He ngawari te whakamahi i tenei hua. Ahakoa karekau e rewa ki te wai matao, ka marara ki te wai me te whakaoho paku. Ka memeha ki roto i te otinga marama ina whakamahana, ka hanga i te kiri maramara me te pakari ina whakamatao. Ka whakamahia i roto i nga rahinga iti, i te nuinga o te 1/3 ki te 1/2 o te nui o te agar me te karagenan. Ka taea te hanga he reera me te inenga o te 0.05% (te nuinga o te whakamahi i te 0.1% ki te 0.3%).
Ko te hua o te gel he nui te wai, he pai te tukunga o te kakara, ka rewa i roto i te waha ina kai.
He pai te whakapumautanga, te atete ki te waikawa me te paheketanga enzymatic. Ka mau tonu te reera ahakoa i raro i nga tikanga tunu kai me te tunu kai, a ka pumau ano ki nga hua waikawa. He tino pai tana mahi ki nga uara pH i waenga i te 4.0 me te 7.5. Ka noho tonu tona kakano i te wa e rokiroki ana, ahakoa nga huringa o te waa me te pāmahana.
