Lub cev thiab tshuaj muaj zog
Dawb kom tawm dawb yooj yim ntws hmoov. Nws yog tsim los ntawm calcium oxide thiab silicon dioxide nyob rau hauv sib txawv proportions thiab yuav muab faib ua dej thiab anhydrous. Insoluble hauv dej, tab sis tuaj yeem tsim gel nrog inorganic acid. Tus nqi pH ntawm 5 feem pua ncua yog 8.4-10.2. Tus txheeb ze ntom ntom yog 2.9. Melting point: 1540 degree
Cov zaub mov additive calcium silicate yog tau los ntawm reacting cov tshiab matured txiv qaub nrog hluavtaws silica.

Daim ntawv thov
Anti-caking agent
GB 2760-2014 qhia tias nws tuaj yeem siv rau cov mis nyuj hmoov (xws li cov mis nyuj qab zib) thiab cov hmoov qab zib thiab nws cov khoom npaj, cheese thiab cov cheese ua tiav thiab nws cov analogues, cov khoom lag luam cocoa (xws li roj, hmoov, muab tshuaj txhuam, muab tshuaj txhuam, txhaws. , thiab lwm yam nrog cocoa raws li cov khoom siv tseem ceeb), cov hmoov txhuv nplej siab thiab cov hmoov txhuv nplej siab, cov khoom qab zib, cov khoom qab zib, cov khoom siv ntsev thiab ntsev, cov txuj lom thiab hmoov, cov khoom sib xyaw ua ke, cov dej qab zib, cov poov xab thiab cov khoom siv poov xab, tsim nyog siv raws li kev xav tau ntau lawm.
FAO / leej twg (1984) teev tias 10g / kg mis hmoov thiab 1g / kg cream hmoov tsuas yog siv rau cov vending machines; Sucrose hmoov 15g / kg thiab qabzib hmoov 15g / kg, siv ib leeg lossis ua ke nrog lwm cov tshuaj tiv thaiv kab mob, tab sis yuav tsum tsis muaj cov hmoov txhuv nplej siab.
Nws kuj tseem siv tau rau 5 feem pua cov hmoov ci thiab 2 feem pua cov lus ntsev. FDA, § 182.2227 (2000) qhia tias cov tshuaj tiv thaiv kab mob ntawm cov lus ntsev thiab ntau yam khoom noj yog 2 feem pua, thiab cov hmoov fermentation yog 5 feem pua (ob qho tib si yog cov feem ntau). EEC (1990) muaj feem xyuam rau lub rooj ntsev (xws li qhiav ntsev, dos ntsev), khoom qab zib, mov, thiab cov pos hniav qab zib.
