Isingeniso

I-Ligustral (eyaziwa nangokuthi i-xanthrin) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-ligustral:

 

Ikhwalithi:

- I-Ligustrum iyi-crystalline eqinile engenambala ukuya kokuphuzi enephunga elimnandi elinamandla ekamelweni lokushisa.

- Iyancibilika kuzincibilikisi zemvelo njenge-ethanol, i-ethers nezincibilikisi ze-ester ekamelweni lokushisa, kodwa cishe ayincibiliki emanzini.

- I-Ligustral inokuguquguquka okuphezulu futhi kulula ukuzithoba.

 

Sebenzisa:

- Isetshenziswa kakhulu embonini ye-flavour njengesithako semvelo sokunambitheka kwesitshalo esingadlulisa izinto ezinephunga elimnandi emikhiqizweni.

 

Indlela:

- I-Ligustrum ingalungiswa nge-oxidation ye-ligustrum (etholakala esithelweni se-ligustrum). I-Ligustrum itholakala ngokusabela ngaphansi kwezimo ezifanele nge-oxidizing ejenti efana ne-acidic potassium permanganate noma umoya-mpilo.

 

Ulwazi Lokuphepha:

- I-Ligustaldehyde ngokuvamile ibhekwa njengenhlanganisela ephephile, kodwa isadinga ukunakekelwa okufanele.

- Iwukucunula okungase kubangele ukucasuka emehlweni, isikhumba, kanye nesimiso sokuphefumula.

- Ukuchayeka ku-ligustrum kufanele kugwenywe ngesikhathi sokusebenza futhi kuqinisekiswe ukungena komoya okuhle.

- Lapho uphatha i-ligustrum, gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko zokuzivikela, namamaski.
