Sida soo-saareyaasha xirfadleyda ah, waxaan jeclaan lahayn inaan ku siino tayo sare leh L () -Ascorbic acid CAS 50-81-7. Oo waxaan ku siin doonaa adeegga ugu fiican ka dib-iibka iyo keenista waqtiga.
Believe Chemical waa hormuudka Shiinaha L () -Ascorbic acid CAS 50-81-7 soo saaraha, alaab-qeybiyaha iyo dhoofiyaha. U hoggaansanaanta raadinta tayada qumman ee alaabta, si markaa L () -Ascorbic acid CAS 50-81-7 ay ku qanacsan yihiin macaamiil badan. Shandong Rumayso
Waxaan ku fiicanahay faa'iidooyinka alaabta kiimikada ee goobta. Alaabadayada waxaa loo dhoofiyaa Yurub, Mareykanka, Japan, Kuuriyada Koonfureed, Koonfur-bari Aasiya iyo dalal kale iyo gobollada. Iyada oo sayniska iyo tignoolajiyada ay yihiin hagaha, daacadnimada aasaaska, tayada nolosha, iyo ku tiirsanaanta fikradda ganacsi ee hal-abuurka iyo horumarka, waxaan si dhab ah u rajaynaynaa in aan abuurno is-weydaarsi iyo iskaashi ballaaran oo lala yeesho macaamiisha gudaha iyo kuwa shisheeye si loo abuuro barwaaqo!
