Te Hydroxypropyl methylcellulose (HPMC)He etera cellulose kore-ionic e whakamahia whānuitia ana i roto i ngā rauemi hanga, rongoā, kai, whakapaipai me ētahi atu ahumahi. Ko ngā tohu hangarau matua o te HPMC ko ngā āhuatanga ā-tinana me te matū, te wairewatanga, te matotoru, te tohu o te whakakapinga, me ētahi atu.
1. Te āhua me ngā āhuatanga taketake
Ko te HPMC he paura mā, he paura mā-parauri rānei, kāore he kakara, kāore he reka, kāore he paitini, he pai te wairewatanga me te pumau i roto i te wai. Ka tere te horapa me te rewa i roto i te wai matao hei hanga i tētahi otinga korori mārama, paku pōuri rānei, ā, he ngoikore te wairewatanga i roto i ngā whakarewa waro.
2. Te matotoru
Ko te matotoru tētahi o ngā tohu hangarau tino nui o te HPMC, e whakatau ana i te mahi a AnxinCel®HPMC i roto i ngā tono rerekē. Ko te matotoru o te HPMC ka inehia i te nuinga o te wā hei otinga wai 2% i te 20°C, ā, ko te awhe matotoru noa mai i te 5 mPa·s ki te 200,000 mPa·s. Ko te teitei ake o te matotoru, ko te kaha ake o te pānga matotoru o te otinga, ā, ko te pai ake o te rheology. Ina whakamahia i roto i ngā ahumahi pēnei i te hanga me te rongoā, me whiriwhiri te taumata matotoru e tika ana kia rite ki ngā hiahia motuhake.
3. Te Ihirangi o te Methoxy me te Hydroxypropoxy
Ko ngā āhuatanga matū o te HPMC ka whakatauhia e ōna nekehanga whakakapinga methoxy (–OCH₃) me te hydroxypropoxy (–OCH₂CHOHCH₃). Ko te HPMC me ngā nekehanga whakakapinga rerekē he rerekē te wairewa, te ngohe mata me te pāmahana whakarewa.
Te Ihirangi Methoxy: I te nuinga o te wā i waenga i te 19.0% me te 30.0%.
Te Ihirangi o te Hydroxypropoxy: I te nuinga o te wā i waenga i te 4.0% me te 12.0%.
4. Te Ihirangi Makuku
Ko te nui o te makuku o te HPMC ka whakahaeretia i te ≤5.0%. Ka pā te nui o te makuku ki te pumau me te pānga o te whakamahinga o te hua.
5. Te Ihirangi o te Pungarehu
Ko te pungarehu te toenga i muri i te tahunga o te HPMC, ko te nuinga mai i ngā tote kore-waro e whakamahia ana i roto i te tukanga whakaputa. Ko te nui o te pungarehu ka whakahaeretia i te ≤1.0%. Mēnā he nui rawa te nui o te pungarehu, ka pāngia te māramatanga me te parakore o te HPMC.
6. Te wairewatanga me te māramatanga
He pai te wairewatanga o te HPMC ki te wai, ā, ka tere te wairewa ki te wai matao hei hanga i tētahi otinga korori rite tonu. Ko te māramatanga o te otinga e whakawhirinaki ana ki te parakore o te HPMC me tōna tukanga waimeha. Ko te otinga HPMC kounga teitei he mārama, he paku miraka rānei.
7. Te pāmahana o te kirikiri
Ka hangaia he tiēre e te wai HPMC i tētahi pāmahana. Ko te pāmahana o te tiēre kei waenganui i te 50 me te 90°C, i runga i te nui o te methoxy me te hydroxypropoxy. He teitei ake te pāmahana tiēre o te HPMC he iti te ihirangi methoxy, engari he iti ake te pāmahana tiēre o te HPMC he nui te ihirangi hydroxypropoxy.
8. te uara pH
Ko te uara pH o te wairewa AnxinCel®HPMC kei waenga i te 5.0 me te 8.0, he kūpapa, he kawakore ngoikore rānei, ā, he pai mō ngā momo taiao tono.
9. Rahi o te Matūriki
Ko te matotoru o te HPMC e whakaatuhia ana ko te ōrau e tika ana kia puta i roto i tētahi mata 80-mesh, 100-mesh rānei. I te nuinga o te wā, me ≥98% te matotoru e tika ana kia puta i roto i tētahi mata 80-mesh kia pai ai te horapa me te wairewa ina whakamahia.
10. Te nui o te konganuku taumaha
Me tutuki te nui o te konganuku taumaha (pērā i te mata me te āheniki) o te HPMC ki ngā paerewa ahumahi e tika ana. I te nuinga o te wā, ko te nui o te mata he ≤10 ppm, ā, ko te nui o te āheniki he ≤3 ppm. Ina koa i roto i te HPMC kai me te rongoā, he tino kaha ake ngā whakaritenga mō te nui o te konganuku taumaha.
11. Ngā tohu moroiti
Mō te AnxinCel®HPMC rongoā me te kai, me whakahaere te poke o ngā moroiti, tae atu ki te maha o ngā koroni, te harore, te rewena, te E. coli, me ētahi atu, ko te tikanga me:
Te tapeke o ngā koroni ≤1000 CFU/g
Te tapeke o te pokepokea ai me te rewena ≤100 CFU/g
Kaua e kitea te E. coli, te Salmonella, me ētahi atu
12. Ngā wāhi tono matua
E whakamahia whānuitia ana te HPMC i roto i ngā ahumahi maha nā te mea he matotoru, he pupuri wai, he hanga kiriata, he whakahinuhinu, he whakaemulsification me ētahi atu āhuatanga:
Ahumahi hanga: Hei whakamātotoru me te pupuri wai i roto i te moata sima, te paura putty, te piripiri taera, me te paninga ātete wai hei whakapai ake i te mahi hanga.
Ahumahi rongoā: Whakamahia hei piripiri, rauemi tuku-roa, me te rauemi mata o te anga kāpūru mō ngā papa rongoā.
Ahumahi kai: whakamahia hei emulsifier, hei whakau, hei whakamātotoru, hei whakamahi i roto i te tiēre, i ngā inu, i ngā kai tunua, me ētahi atu.
Te ahumahi matū o ia rā: e whakamahia ana hei whakamātotoru me te whakaū i te emulsifier i roto i ngā hua tiaki kiri, ngā hopi horoi, me ngā shampoo.
Ngā tohu hangarau oHPMCkei roto ko te matotoru, te nui o te whakakapinga (te ihirangi o te rōpū waikura), te makuku, te ihirangi pungarehu, te uara pH, te pāmahana tiēre, te pai, te ihirangi konganuku taumaha, me ētahi atu. Mā ēnei tohu ka whakatau i tana mahi tono i roto i ngā mara rerekē. I te wā e whiriwhiri ana i te HPMC, me whakatau ngā kaiwhakamahi i ngā whakaritenga tika kia rite ki ngā whakaritenga tono motuhake kia pai ai te whakamahinga.
