Pectin ntau lawm yuav tsum muaj cov cuab yeej kim thiab nyuaj. Los ntawm thiab loj, E440 tuaj yeem muab rho tawm los ntawm yuav luag txhua cov txiv hmab txiv ntoo los ntawm kev rho tawm. Tom qab tau txais cov pectin extract, nws tau ua tib zoo ua tiav siv cov cuab yeej tshwj xeeb kom txog thaum cov khoom tau txais cov khoom tsim nyog. Properties. Nyob rau hauv Russia, zus tau tej cov E440 tseem ceeb heev. Pectin feem ntau yog muab rho tawm los ntawm txiv apples thiab beets. Raws li kev txheeb cais, kwv yees li 30 tons ntawm cov tshuaj tau tsim txhua xyoo hauv Russia.

Kev sib xyaw ntawm pectin
