Setache se fetotsoeng ke eng?

Setache se fetotsoeng se bolela starch e fetotsoeng ka lik'hemik'hale kapa 'meleng ho ntlafatsa thepa ea eona ea ts'ebetso bakeng sa lits'ebetso tse ikhethileng.Starch, polymer ea carbohydrate e nang le likarolo tsa tsoekere, e fumaneha ka bongata limeleng tse ngata 'me e sebetsa e le mohloli o moholo oa matla ho batho le liphoofolo.Litache tse fetotsoeng li sebelisoa haholo liindastering tse fapaneng, ho kenyelletsa lijo, meriana, masela le tlhahiso ea pampiri.Mona ke kakaretso ea starch e fetotsoeng:

Mekhoa ea ho fetola:

1. Phetoho ea Lik'hemik'hale: Mekhoa ea lik'hemik'hale e kenyelletsa ho phekola starch ka li-acids, alkalis, kapa li-enzyme ho fetola sebopeho sa eona sa molek'hule.Mekhoa e tloaelehileng ea ho fetola lik'hemik'hale e kenyelletsa etherification, esterification, cross-linking, oxidation, le hydrolysis.
2. Phetoho ea 'Mele: Mekhoa ea' mele e kenyelletsa kalafo ea mochini kapa ea mocheso ho fetola thepa ea 'mele ea starch ntle le phetoho ea lik'hemik'hale.Mekhoa ena e kenyelletsa ho futhumatsa, ho kuta, extrusion, le crystallization.

Thepa ea Modified Starch:

• Thickening le Gelling: Li-starche tse fetotsoeng li bonts'a thepa e ntlafetseng ea ho teteka le ea gelling ha e bapisoa le starch ea tlhaho, e etsa hore e be li-additives tsa bohlokoa lihlahisoa tsa lijo tse kang li-sauces, sopho, gravies le li-dessert.
• Botsitso: Litache tse fetotsoeng li ka 'na tsa matlafatsa botsitso linthong tse kang mocheso, asiti, ho kuta, le potoloho ea ho qhibiliha, e leng se lumellang hore ho be le ts'ebetso e ntlafetseng ea ho lokisa le ho boloka lijo.
• Taolo ea Viscosity: Litache tse fetotsoeng li ka etsoa hore li fane ka lintlha tse ikhethang tsa viscosity, tse lumellang taolo e nepahetseng holim'a sebopeho le botsitso ba lihlahisoa tsa lijo.
• Ho hlaka: Litache tse ling tse fetotsoeng li fana ka ho hlaka le pepeneneng litharollong, li etsa hore li tšoanelehe ho sebelisoa lihlahisoa tsa lijo tse hlakileng kapa tse fetohang.
• Freeze-Thaw Stability: Litache tse ling tse fetotsoeng li bonts'a botsitso bo ntlafetseng ba ho qhibiliha, ho etsa hore li lokele ho sebelisoa lihlahisoa tsa lijo tse leqhoa.

Lisebelisoa:

1. Indasteri ea Lijo: Litache tse fetotsoeng li sebelisoa haholo e le li-thickeners, stabilizers, gelling agents le li-emulsifiers lihlahisoa tsa lijo tse fapa-fapaneng, ho akarelletsa le li-sauces, li-dressing, sopho, li-dessert, lintho tsa baka le nama e phehiloeng.
2. Meriana ea Meriana: Ka indasteri ea meriana, li-starche tse fetotsoeng li sebelisoa e le li-binders, disintegrants, fillers, le li-agent tse laoloang ka mokhoa oa ho lokolloa ha matlapa le mefuta e meng ea litekanyetso tsa molomo.
3. Masela: Litache tse fetotsoeng li sebelisoa ho boholo ba masela ho ntlafatsa matla a likhoele, mafura le boleng ba masela nakong ea ho loha le ho phethela.
4. Ho Etsa Lipampiri: Ha ho etsoa lipampiri, li-starche tse fetotsoeng li sebelisoa e le lisebelisoa tsa boholo ba holim'a metsi, li-binders tse koahelang, le li-additives tse ka hare ho ntlafatsa matla a pampiri, khatiso le thepa ea holim'a metsi.
5. Likhomaretsi: Litache tse fetotsoeng li sebelisoa e le li-binders le likhomaretsi lits'ebetsong tse fapaneng, ho kenyeletsoa ho laminating ka paperboard, corrugating le plywood.

Polokeho le Melawana:

• Litache tse fetotsoeng tse sebelisoang lits'ebetsong tsa lijo le tsa meriana li tlas'a taolo ea taolo 'me li tlameha ho lumellana le litekanyetso tsa tšireletso tse thehiloeng ke mekhatlo ea tsamaiso e kang Food and Drug Administration (FDA) United States le European Food Safety Authority (EFSA) European Union. .
• Mekhatlo ena ea taolo e lekola polokeho ea starch e fetotsoeng ho latela lintlha tse kang bohloeki, sebopeho, ts'ebeliso e reriloeng, le litlamorao tse ka bang teng tsa bophelo bo botle.

Li-starche tse fetotsoeng li bapala karolo ea bohlokoa liindastering tse fapaneng, tse fanang ka thepa e ntlafalitsoeng ea ts'ebetso le maemo a fapaneng bakeng sa lits'ebetso tse fapaneng.Ka ho fetola sebopeho sa limolek'hule tsa starch, bahlahisi ba ka hlophisa thepa ea eona hore e finyelle litlhoko tse khethehileng tsa ts'ebetso, e leng se lebisang ho boleng bo phahameng ba sehlahisoa, botsitso le khotsofalo ea bareki.
