Iimpawu eziphambili zeHydroxypropyl Starch Ether
Iimpawu eziphambili zokusebenza zeHPSE ziquka:
Ukunyibilika kunye neGelation
HPS yiyoUkunyibilika emanzini, ngokungafaniyo nesitatshi somthonyama, esenza iijeli xa kufudunyezwa emanzini. Oku kunyibilika kwenza i-HPS ixabiseke kwizicelo apho ukubunjwa kwejeli kunganqweneleki, njengeemveliso ezithile zokutya, ukwakheka kwamayeza, kunye neenkqubo zoshishino. Ngaphezu koko, i-HPS inokwenza ii-gel ezizinzile kumaqondo okushisa ahlukeneyo kunye nobukho beetyuwa, eziluncedo kwizicelo ezithile zokutya kunye namayeza.
Viscosity
Izisombululo ze-HPS zibonisai-viscosity ephezulu kwiindawo eziphantsi, iyenza ibe yinto eluncedo yokujiya. I-viscosity ye-HPS inokulungelelaniswa ngokusekelwe kwinqanaba le-hydroxypropyl substitution, echaphazela amandla okugcina amanzi kunye nobukhulu besisombululo. Isakhono sayo sokuguqula i-viscosity kuluhlu olubanzi lubalulekile kwizicelo ezahlukeneyo, kubandakanywa nokutyebisa kwizinto zokuthambisa kunye neemveliso zokutya.
Uzinzo
I-HPS ibonisauzinzo olubalaseleyophantsi kweemeko ezahlukeneyo, kubandakanywa ukushisa okuphezulu, indawo ephantsi kunye nephezulu ye-pH, kunye nobukho be-electrolytes. Olu uzinzo luyenza ibe ngumgqatswa ofanelekileyo wokusetyenziswa kokubini kokutya kunye nokuveliswa kokungatyiyo okudinga ixesha elide lobomi kunye nokusebenza okungaguqukiyo, njengakwizinto zokuthambisa kunye namayeza.
Ukwenza ifilimu kunye neePropati eziBophelelayo
Ngenxa yobuchule bayo bokwenza iifilimu kunye nobuchule bayo bokubopha, i-HPS isoloko isetyenziselwa ukugquma, ukwakhiwa kweethebhulethi, kunye nezinye iimveliso apho kufuneka i-arhente yokwenza ifilimu. I-adhesive yayo kunye neempawu ezibophezelayo zenza ukuba kube yinto ethandwayo yokusetyenziswa kwiingubo zokutya, iipilisi zamachiza, kunye nezinye izicelo apho ezi mpawu ziyimfuneko.
Ayinatyhefu kunye neBiodegradable
I-HPS ngokubanzi ithathwa njengeikhuselekile (GRAS)yokusetyenziswa kwiimveliso zokutya kwaye ii-biodegradable, iyenza ibe yindlela ehambelana nokusingqongileyo kwiipolima zokwenziwa. Le propati inegalelo ekwandeni kwemfuno yayo kwizicelo ezizinzileyo, ezinje nge-biodegradable packages kunye namayeza anoxanduva lokusingqongileyo.

Ukusetyenziswa kwe-Hydroxypropyl Starch Etere
Ishishini lokutya
I-HPS iqhele ukusetyenziswa kwishishini lokutya njengei-agent etyebisayo, i-stabilizer, kunye ne-emulsifier. Ukukwazi kwayo ukwenza izisombululo ezizinzileyo kunye nokugcina ukufuma kwenza ukuba ilungele ukusetyenziswa kwiisuphu, iisosi, ukunxiba, kunye needessert. Ikwasetyenziselwa ukuveliswa kokutya okukhawulezayo kunye nokutya okucutshungulwayo, apho kunceda ukuphucula ukuthungwa kunye nobomi beshelufu. Ikhono le-HPS lokuthintela i-syneresis (ukwahlulwa kolwelo kwijeli) kuphucula umgangatho kunye nokuhambelana kweemveliso zokutya.
Imizekelo:
