Tlhaloso ea Sehlahisoa sa Carrageenan

Kakaretso Thepa

Carrageenan ka kakaretso ke phofo e tshweu ho isa ho bosehla bo sootho, ha e na monko ebile ha e latswehe, mme dihlahiswa tse ding di na le tatso e nyane ya lehola la lewatle. Gel e entsoeng ke carrageenan ke thermoreversible, ke hore, e qhibiliha ka tharollo ka mor'a ho futhumatsa, 'me e etsa gel hape ha tharollo e pholile.

Thepa ea 'Mele le ea Lik'hemik'hale

Carrageenan ha e na chefo 'me e na le litšobotsi tsa ho kopanya, ho qhibiliha, botsitso, viscosity le reactivity. Ka hona, e ka sebelisoa e le coagulant, thickener, emulsifier, suspending agent, adhesive, molding agent le stabilizer tlhahiso ea indasteri ea lijo.

Kopo indastering ea lijo

Carrageenan e 'nile ea sebelisoa e le tlatsetso ea tlhaho ea lijo ka lilemo tse ngata. Ke fiber ea semela e se nang kotsi e ka thusang tšilo ea lijo 'me e na le mefuta e mengata ea tšebeliso. Tlhahiso ea khoebo ea carrageenan linaheng tse ling e qalile lilemong tsa bo-1920, 'me Chaena e ile ea qala ho hlahisa carrageenan ea khoebo ka 1985, eo 80% ea eona e sebelisoang lijong kapa indastering e amanang le lijo.

Carrageenan e ka etsa li-gel tse semi-solid. Ke coagulant e babatsehang bakeng sa ho etsa jelly ea litholoana. E tiisa mocheso oa kamore. Gel e entsoeng e tiile, e pepenene haholo, 'me ha ho bonolo ho oa. E ka boela ea sebelisoa ho eketsa limatlafatsi ho etsa phofo ea jelly. Ha u ja, ho bonolo haholo ho e qhaqha ka metsing. E ka boela ea sebelisoa e le coagulant bakeng sa pudding ea lebese le pudding ea litholoana. E na le litšoaneleho tsa ho boloka metsi a tlaase, sebopeho se setle, viscosity e tlaase, le ho fetisa mocheso o motle. Ha u pheha pente ea linaoa ka yokan, carrageenan e ka eketsoa e le coagulant. Jelly e entsoeng ka makotikoting e entsoeng ka carrageenan e le coagulant e bonolo haholo ho ja le ho jara. E na le litholoana 'me e na le phepo e nepahetseng ho feta jelly ea litholoana tse tloaelehileng. Carrageenan e ka boela ea sebelisoa e le coagulant bakeng sa nama e entsoeng ka makotikoting, hape e ka sebelisoa e le stabilizer, suspending agent, forming agent, clarifier, thickener, adhesive, joalo-joalo.

Ha u etsa lipompong tse pepeneneng tse bonolo, haeba carrageenan e sebelisoa e le coagulant, pompong e bonolo e na le pepenene e phahameng, e khatholla ebile ha e khomarele meno. Ho eketsa carrageenan ho lipompong tse thata ka kakaretso ho ka etsa hore sebopeho sa sehlahisoa se be se ts'oanang le se boreleli, 'me se eketsa botsitso.

Carrageenan, ntho e hloekileng ea tlhaho, e na le thepa e babatsehang e kang reactivity e matla, bokhoni ba ho etsa li-gel le litharollo tse phahameng tsa viscosity, le botsitso bo phahameng. Har'a li-polymers tsohle tse qhibilihang ka metsing, e ikhethile ka ho ts'oaroa ha eona hape le liprotheine. Elasticity e khotsofatsang, pepeneneng le ho qhibiliha ho ka eketsa mefuta ea eona ea ts'ebeliso. Thepa ea eona e sireletsehileng le e se nang chefo e tiisitsoe ke Komiti e Kopanetsoeng ea Setsebi ea Li-additives (JECFA) ea Mokhatlo oa Lijo le Temo oa Machaba a Kopaneng le Mokhatlo oa Lefatše oa Bophelo, o lumelang hore carrageenan e lokela ho sebelisoa haholo indastering ea lijo, indasteri ea lik'hemik'hale, biochemistry, lipatlisiso tsa bongaka le likarolo tse ling. Ka hona, lilemong tsa morao tjena, carrageenan e tsoetse pele ka potlako lapeng le linaheng tse ling, 'me tlhokahalo e eketsehile haholo. Mosebetsi oa eona o ikhethang o ke ke oa nkeloa sebaka ke li-resin tse ling, tse lebisitseng ho nts'etsopele e potlakileng ea indasteri ea carrageenan. Hona joale kakaretso ea selemo le selemo ea carrageenan lefatšeng e feta hōle tlhahiso ea agar.

Carrageenan e qalile ho sebelisoa haholo Europe le United States, 'me tlhahiso ea lefats'e ea carrageenan e boemong ba bobeli har'a marenene a jeoang a ntšitsoeng ka leoatleng. Lilemong tsa morao tjena, naha ea heso e kenyelelitse carrageenan lethathamong la li-additives tsa lijo. Carrageenan e boetse e kenyelelitsoe litaelong tsa litekanyetso tsa lijo tsa Mokhatlo oa Lijo le Temo oa Machaba a Kopaneng le Mokhatlo oa Lefatše oa Bophelo. Ka bokhutšoanyane, carrageenan e kopana le litekanyetso tsa lijo tsa Sechaena le tsa linaha tse ling 'me e na le menyetla e pharaletseng ea tšebeliso.
