Hoʻolauna

ʻO Vanillin, i kapa ʻia ʻo vanillin, he mea hoʻohuihui kūlohelohe me kahi ʻala kū hoʻokahi a me ka ʻono.

 

Nui nā ala e hana ai i ka vanillin. ʻO ke ala maʻamau i hoʻohana ʻia i unuhi ʻia a i ʻole synthesized mai vanilla maoli. Loaʻa i nā ʻāpana vanilla maoli ka resin mauʻu i unuhi ʻia mai nā ʻōpala pīni vanilla a me ka vanillin lāʻau i unuhi ʻia mai ka lāʻau. ʻO ke ʻano synthesis ka hoʻohana ʻana i ka phenol maka ma o ka hopena condensation phenolic e hana ai i ka vanillin.

ʻO ka vanillin kahi mea puhi a pono e mālama ʻia mai nā lapalapa ākea a me nā wela kiʻekiʻe. E hoʻohana i nā mīkina lima pale a me nā maka aniani i ka wā o ka hana e pale aku i ka pili ʻana me ka ʻili a me nā maka. Pono e pale ʻia ka inhalation o kona lepo a i ʻole nā ​​​​huehue a pono e hoʻokō ʻia nā hana ma nā wahi maikaʻi. Manaʻo ʻia ʻo Vanillin he kemika palekana ʻaʻole e hōʻeha i nā kānaka ke hoʻohana ʻia a mālama pono ʻia. Eia nō naʻe, no kekahi poʻe me ka maʻi ʻaleʻale, hiki i ka wā lōʻihi a i ʻole ka nui o ka hoʻolaha ʻana i ka vanillin ke kumu i nā hopena maʻi a pono e hoʻohana ʻia me ka akahele.
