Kutheni i-sodium benzoate ekutyeni?

Uphuhliso lweshishini lokutya luye lwakhokelela ekuphuhlisweni kwezongezo zokutya.Ibakala lokutya le-sodium benzoatesesona sigcini-xesha eside kwaye sisetyenziswa kakhulu kwaye sisetyenziswa kakhulu kwiimveliso zokutya.Kodwa iqulethe ubuthi, ngoko Kutheni i-sodium benzoate isekutyeni?

I-sodium benzoatesisichiza sokungunda kwaye eyona mpembelelo yayo ingcono yokuthintela ikuluhlu lwe-pH lwe-2.5 - 4. Xa i-pH> 5.5, ayisebenzi kangako kwizingundo ezininzi kunye negwele.Ubuncinci boxinzelelo lwe-benzoic acid ngu-0.05% - 0.1%.Ubuthi bayo bunyibilika esibindini xa ingena emzimbeni.Kukho iingxelo zamazwe ngamazwe zetyhefu ebekwe ngaphezulu kokusetyenziswa kwesodium benzoate njengesigcini.Nangona kungekabikho ukuqonda okumanyeneyo, kwamanye amazwe nakwimimandla kuye kwavalwa amalungiselelo, njengeUnited States, iJapan, neHong Kong kuye kwavalwa ukutya okunkonkxiweyo ngayo.I-Potassium sorbate, enetyhefu encinci, isetyenziswa ngokubanzi.Njengoko unyibiliko lwamanzi lungekho mgangathweni, ngoko ngokuqhelekileyo lwenziwa ukunyibilika kakuhle kwamanzi kwi-sodium benzoate application.Isetyenziselwa kakhulu ukugcina kunye nokuthintela ukungunda kwiimveliso ezifana nesosi yesoya, iviniga, i-pickle, kunye neziselo ze-carbonated.

Ngokujonga iinkxalabo zokhuseleko, nangona amazwe amaninzi esavumela i-sodium benzoate njengoko isigcinakaliso sisongezwa ekutyeni, umda wosetyenziso uye usiba mxinwa kakhulu kwaye isixa sesongezo sibekwe esweni ngokungqongqo.E-USA, ubuninzi obuvunyelwe ukusetyenziswa kwayo yi-0.1 wt%.Umgangatho wangoku wokhuseleko lokutya wesizwe waseTshayina GB2760-2016 "Umgangatho wokusetyenziswa kwezongezo zokutya" umisela umda wokusetyenziswa kwe "benzoic acid kunye netyuwa yesodium", kunye nomda omkhulu we-0.2g / kg kwiziselo ze-carbonated, 1.0g /kg yeziselo ezisekelwe kwizityalo kunye ne-1.0g/kg yeziselo zeziqhamo kunye nemifuno (i-pulp).Injongo yokongeza izithinteli zokutya kukuphucula umgangatho wokutya, ukwandisa ixesha leshelufu, ukuququzelela ukusetyenzwa kunye nokugcina isiqulatho sesondlo.Ukongezwa kwe-sodium benzoate kuvunyelwe kwaye kukhuselekile ukuba nje kuqhutyelwa ngokuhambelana noluhlu lweentlobo kunye nobungakanani bokusetyenziswa obuchazwe ngurhulumente.
