Isingeniso

I-Vanillin, eyaziwa ngamakhemikhali ngokuthi i-vanillin, iyinhlanganisela ye-organic enephunga eliyingqayizivele nokunambitheka.

 

Kunezindlela eziningana zokwenza i-vanillin. Indlela esetshenziswa kakhulu ikhishwa noma ihlanganiswe ku-vanilla yemvelo. Izingcaphuno zemvelo ze-vanilla zihlanganisa inhlaka yotshani ekhishwe kuma-pods kabhontshisi we-vanilla kanye ne-vanillin yokhuni ekhishwe okhunini. Indlela yokuhlanganisa ukusebenzisa i-phenol eluhlaza ngokusabela kwe-phenolic condensation ukuze kukhiqizwe i-vanillin.

I-Vanillin iyinto evuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu. Gqoka amagilavu ​​okuzivikela kanye nezibuko ngesikhathi usebenza ukuze ugweme ukuthintana nesikhumba namehlo. Ukuhogela uthuli noma umhwamuko wayo nakho kufanele kugwenywe futhi ukusebenza kufanele kwenziwe ezindaweni ezinomoya omuhle. I-Vanillin ngokuvamile ibhekwa njengekhemikhali ephephile uma iqhathaniswa nengozi enkulu kubantu uma isetshenziswe futhi igcinwe ngendlela efanele. Kodwa-ke, kwabanye abantu abane-allergies, ukuchayeka isikhathi eside noma okukhulu ku-vanillin kungabangela ukungezwani komzimba futhi kufanele kusetshenziswe ngokuqapha.
