Hydroxypropylmethylcellulose (HPMC) ke motsoako o sebetsang ka bongata le o sebelisoang haholo indastering ea lijo.HPMC, e tsoang ho selulose e nkiloeng ho likhoele tsa tlhaho tsa semela, e tsebahala ka mesebetsi ea eona e mengata.
1. Selelekela sa Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose ke semi-synthetic polymer e nkiloeng ho selulose ea tlhaho ea semela.Hangata e sebelisoa indastering ea lijo e le setenya, se tsitsitseng le emulsifier.Tlhahiso ea HPMC e kenyelletsa phetoho ea selulose ka etherification, ho hlahisa hydroxypropyl le lihlopha tsa methyl ho ntlafatsa thepa ea eona ea ts'ebetso.
2. Litšobotsi tsa HPMC
2.1 Solubility
HPMC e qhibiliha ka metsing 'me e etsa tharollo e hlakileng le e hlakileng.Solubility e ka fetoloa ka ho fetola boemo ba sebaka sa hydroxypropyl le lihlopha tsa methyl.
2.2 Viscosity
E 'ngoe ea thepa ea bohlokoa ea HPMC ke bokhoni ba eona ba ho fetola viscosity ea lihlahisoa tsa lijo.E sebetsa e le ntho e matlafatsang, e amang sebopeho le molomo oa litlolo tse fapaneng tsa lijo.
2.3 Ho tsitsa ha mocheso
HPMC e na le botsitso bo botle ba mocheso mme e loketse lits'ebetso tsa lijo tse chesang le tse batang.Thepa ena e bohlokoa haholo lits'ebetsong tse kang ho pheha le ho baka.
2.4 Bokhoni ba ho etsa lifilimi
HPMC e ka etsa filimi e fanang ka tšitiso ho thusa ho boloka mongobo le ho lelefatsa bophelo ba lishelefo ea lijo tse ling.Thepa ena e bohlokoa lits'ebetsong tse kang ho roala lipompong.
3. Tšebeliso ea HPMC lijong
3.1 Thickener
HPMC e sebediswa ka tlwaelo e le ntho e tiisang dihlahiswa tsa dijo tse kang disoso, sopho le meseho.Bokhoni ba eona ba ho haha viscosity bo thusa ho fihlela sebopeho le botsitso bo hlokahalang mefuteng ena.
3.2 Li-stabilizers le li-emulsifiers
Ka lebaka la thepa ea eona ea emulsifying, HPMC e thusa ho tsitsisa li-emulsion lihlahisoa tse kang liaparo tsa salate le mayonnaise.E thibela ho arohana ha likarolo tsa oli le metsi le ho netefatsa sehlahisoa se ts'oanang le se tsitsitseng.
3.3 Lisebelisoa tsa ho baka
Lefapheng la ho baka, HPMC e sebelisoa ho ntlafatsa rheology ea hlama le ho fana ka sebopeho se betere le sebopeho sa thepa e halikiloeng.E boetse e sebetsa joalo ka moisturizer, e thibelang ho sisinyeha le ho ntlafatsa bocha.
3.4 Lihlahisoa tsa lebese le lijo tse theolelang tse hatselitsoeng
HPMC e sebelisoa tlhahisong ea lihlahisoa tsa lebese le li-dessert tse hatselitsoeng ho laola viscosity, ho thibela sebopeho sa kristale ea leqhoa le ho ntlafatsa tatso ea kakaretso ea lihlahisoa tsena.
3.5 Lihlahisoa tse se nang Gluten
Bakeng sa lihlahisoa tse se nang gluten, HPMC e ka sebelisoa ho etsisa litšobotsi tsa viscoelastic tsa gluten, ho fana ka sebopeho le ho ntlafatsa sebopeho sa thepa e sa behoang ea gluten.
3.6 Lihlahisoa tsa nama le likhoho
Ka nama le lihlahisoa tsa likhoho, HPMC e sebetsa e le tlamahano, e ntlafatsa ho boloka metsi, sebopeho le lihlahisoa tsa lihlahisoa ka kakaretso.
4. Melemo ea HPMC lijong
4.1 Hloekile Label
HPMC hangata e nkuoa e le motsoako o hloekileng oa lileibole hobane e tsoa mehloling ea limela 'me e sebetsa hanyane.Sena se lumellana le khetho ea bareki bakeng sa lijo tsa tlhaho le tse sa sebelisoang hanyane.
4.2 Ho feto-fetoha ha maemo
Ho feto-fetoha ha maemo ha HPMC ho e lumella hore e sebelisoe lihlahisoa tse fapaneng tsa lijo, e fa bahlahisi motsoako o le mong o nang le mesebetsi e mengata.
4.3 Ntlafatsa sebopeho le tatso
Tšebeliso ea HPMC e thusa ho ntlafatsa sebopeho le molomo oa mefuta e fapaneng ea lijo, ho ntlafatsa litšobotsi tsa kutlo ka kakaretso.
4.4 Eketsa bophelo ba shelofo
Lihlahisoang moo thepa ea ho etsa lifilimi e leng ea bohlokoa, e kang ho roala lipompong, HPMC e thusa ho lelefatsa bophelo ba sethala ka ho fana ka thibelo e sireletsang khahlanong le mongobo le lintho tse ling tse ka ntle.
5. Tsepamiso le maikutlo
5.1 Likokoana-hloko tse ka bang teng
Le ha HPMC ka boyona e se ntho e hanang mmele, ho ka ba le dingongoreho tse amanang le thepa eo e nkiloeng ho yona (selulose), haholoholo ho batho ba nang le dintho tse amanang le cellulose.Leha ho le joalo, ho kula hona ha hoa tloaeleha.
5.2 Maikutlo a taolo
Mekhatlo e laolang e kang US Food and Drug Administration (FDA) le European Food Safety Authority (EFSA) e hlahisitse tataiso mabapi le tšebeliso ea HPMC lijong.Ho latela melao ena ho bohlokoa ho bahlahisi.
5.3 Maemo a ts'ebetso
Ho sebetsa hantle ha HPMC ho ka angoa ke maemo a ts'ebetso joalo ka mocheso le pH.Baetsi ba lokela ho ntlafatsa liparamente tsena ho netefatsa hore litšobotsi tse lakatsehang tsa ts'ebetso lia fihlelleha.
Hydroxypropylmethylcellulose (HPMC) e na le karolo ea bohlokoa indastering ea lijo mme ke motsoako o sebetsang ka mefuta e mengata e fapaneng ea ts'ebeliso.Thepa ea eona e ikhethang e etsa hore e be ea bohlokoa bakeng sa ho finyella sebopeho se itseng, botsitso le lipakane tsa bophelo ba lishelefo ka mefuta e sa tšoaneng ea lijo.Leha ho na le menahano ea allergenicity le melao ea tsamaiso, HPMC e ntse e le khetho ea pele bakeng sa baetsi ba lijo ba batlang metsoako e sebetsang le e hloekileng.Ha lipatlisiso le nts'etsopele indastering ea lijo li ntse li tsoela pele, HPMC e kanna ea tsoela pele ho boloka bohlokoa ba eona e le motsoako oa mantlha mefuteng e fapaneng ea lijo.
