Ukusetshenziswa
I-DL - Tartaric Acid iyinhlanganisela eguquguqukayo enezinhlelo zokusebenza ezahlukahlukene. Isetshenziswa kabanzi embonini yokudla neziphuzo njenge-acidulant, i-flavour enhancer, kanye ne-pH regulator. Inganikeza ukunambitheka okumuncu futhi ithuthukise ukunambitheka kwemikhiqizo efana neziphuzo ezibandayo, amajusi ezithelo, namaswidi. Embonini yemithi, isetshenziswa ekwakhiweni kwemithi kanye ne-chiral resolving agent. Ngaphezu kwalokho, i-DL - Tartaric Acid isetshenziswa embonini yamakhemikhali ekuhlanganiseni ama-ester kanye nezinye izinto eziphilayo. Iphinde isetshenziswe kweminye imikhiqizo yezimonyo kanye neyokunakekela umuntu siqu ukulungisa i-pH nokuthuthukisa ukuzinza kwezakhi.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
