Ibakala lokutya i-sodium carboxymethyl cellulose (CMC)

I-sodium carboxymethyl cellulose yamkelwa njengesongezo sokutya esikhuselekileyo. Yamkelwa kwilizwe lam ngeminyaka yee-1970 kwaye yayisetyenziswa kakhulu ngeminyaka yee-1990. Yeyona isetyenziswa kakhulu kwaye isixa esikhulu seselulosi ehlabathini namhlanje.

Ukusetyenziswa okusisiseko

Isetyenziswe njenge-thickener kushishino lokutya, njengomphathi weziyobisi kwishishini lamachiza, kunye ne-binder kunye ne-anti-redeposition agent kwishishini lemichiza yemihla ngemihla. Kwishishini lokuprinta kunye nokudaya, lisetyenziswa njenge-colloid yokukhusela kwi-agent ye-agent kunye ne-printing paste, njl. Ingabonwa ukuba i-sodium carboxymethyl cellulose inoluhlu olubanzi lokusetyenziswa.

Ukusetyenziswa kwe-CMC kuKutya

Ukusetyenziswa kwe-CMC ecocekileyo ekutyeni kuye kwavunywa yi-FAO kunye ne-WHO. Ivunywa emva kwezifundo kunye novavanyo olungqongqo lwebhayoloji kunye netyhefu. Ukwamkelwa okukhuselekileyo okusemgangathweni wamazwe ngamazwe (ADI) yi-25mg/(kg·d) , oko kukuthi, malunga ne-1.5 g/d ngomntu ngamnye. Kuye kwaxelwa ukuba akukho mpendulo enetyhefu xa uvavanyo lufikelela kwi-10 kg. I-CMC ayisiyiyo kuphela i-emulsion stabilizer efanelekileyo kunye ne-thickener kwizicelo zokutya, kodwa inozinzo oluhle kakhulu lokukhenkceza kunye nokunyibilika, kwaye inokuphucula incasa yemveliso kunye nokwandisa ixesha lokugcina. Umthamo kubisi lwesoya, i-ayisikrimu, i-ayisikrimu, ijeli, isiselo kunye nokutya okusemathinini malunga ne-1% ukuya kwi-1.5%. I-CMC inokwenza i-emulsion ezinzileyo yokusabalalisa ngeviniga, isosi yesoya, ioli yemifuno, ijusi yeziqhamo, i-gravy, ijusi yemifuno, njl njl. Idosi yi-0.2% ukuya kwi-0.5%. Ngokukodwa, ineempawu ezigqwesileyo ze-emulsifying zezilwanyana kunye nemifuno yeoli, iiprotheni kunye nezisombululo zamanzi, ezivumela ukuba zenze i-emulsion ye-homogeneous kunye neepropati ezizinzileyo. Ngenxa yokhuseleko kunye nokuthembeka kwayo, idosi yayo ayithintelwanga ngumgangatho wesizwe wokucoceka kokutya kwe-ADI. I-CMC iphuhliswe ngokuqhubekayo kwintsimi yokutya, kwaye kwiminyaka yakutshanje, uphando malunga nokusetyenziswa kwe-sodium carboxymethyl cellulose kwimveliso yewayini luye lwenziwa.
