Kev Siv
Ethyl vanillin yog ib yam khoom noj uas tau tso cai los ntawm Tuam Tshoj "Hygienic Standards for the Use of Food Additives". Nws lub zog tsw qab yog 3 txog 4 npaug ntawm vanillin. Nws feem ntau yog siv rau hauv kev ua cov khoom noj vanilla, dej qab zib, ice cream, chocolate, luam yeeb, cawv, thiab lwm yam. Tus nqi siv hauv chocolate yog 250mg/kg; hauv chewing gum, nws yog 110mg/kg; hauv cov dej cawv, 100mg/kg; hauv puddings, 74mg/kg; hauv khoom qab zib, 65mg/kg; hauv cov khoom ci, 63mg/kg; hauv cov dej txias, 47mg/kg; thiab hauv cov dej qab zib, 20mg/kg.
GB2760—96 hais tias nws yog ib qho khoom noj uas raug tso cai siv ib ntus. Nws feem ntau yog siv rau hauv kev npaj cov tsw qab rau vanilla, chocolate, dej qab zib, ice cream, thiab lwm yam. Raws li cov cai ntawm FAO/WHO (1983): Nws tuaj yeem siv rau hauv cov khoom noj hauv kaus poom rau menyuam yaus thiab cov khoom ua tiav rau cov menyuam mos thiab cov menyuam yaus, nrog rau qhov ntau tshaj plaws uas tso cai yog 70mg/kg (hais txog cov khoom noj nplej); rau hmoov cocoa, hmoov cocoa uas muaj suab thaj, chocolate, cocoa cawv, cocoa ncuav mog qab zib, cov khoom siv cocoa-coated (siv me me rau cov tsw qab) thiab mis nyuj, qhov ntau npaum li cas tsuas yog txwv rau kev ua tiav (GMP).
Ethyl vanillin yog ib yam khoom siv ua kom tsw qab dav dav thiab yog ib yam khoom siv ua kom tsw qab tseem ceeb tshaj plaws hauv ntiaj teb niaj hnub no. Nws yog ib yam khoom siv tseem ceeb hauv kev lag luam khoom noj khoom haus. Nws cov ntxhiab tsw qab yog 3 txog 4 npaug ntawm vanillin, thiab cov ntxhiab tsw qab kav ntev dua. Vim nws cov ntxhiab tsw qab muaj zog thiab ntxiv me ntsis, nws tuaj yeem txo qhov iab hauv zaub mov raws li Chemicalbook. Nws yog ib yam khoom siv hloov vanillin thiab tuaj yeem txo cov nqi. Nws siv dav hauv zaub mov, chocolate, ice cream, dej haus, thiab cov tshuaj pleev ib ce txhua hnub los txhim kho thiab kho cov ntxhiab tsw qab. Tsis tas li ntawd, ethyl vanillin kuj tseem siv tau ua cov khoom noj khoom haus ntxiv thiab ib qho nruab nrab hauv kev lag luam tshuaj.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
