Loaʻa kēia i nā nuances kemika kikoʻī e wehewehe i ka maikaʻi a me ke ʻano o ka Milk Lactone.

Eia kahi wehewehe kikoʻī:

1. ʻO ke Kemika: No ke aha he mea nui ka Isomerism i nā Lactones

No nā lactones e like me δ-Decalactone, ʻaʻole pili ka inoa "cis" a me "trans" i kahi paʻa pālua (e like me ia i loko o nā molekala e like me nā waikawa momona) akā i ka stereochemistry pili ma nā kikowaena chiral ʻelua ma ke apo. Hoʻokumu ke apo i ke kūlana kahi i ʻokoʻa ai ka ʻano kikoʻī o nā ʻātoma hydrogen a me ke kaulahao alkyl e pili ana i ka mokulele apo.

· cis-Isomer: Aia nā ʻātoma hydrogen ma nā ʻātoma kalapona kūpono ma ka ʻaoʻao like o ka mokulele apo. Hoʻokumu kēia i kahi ʻano kikoʻī, ʻoi aku ka paʻa.

· Trans-Isomer: Aia nā ʻātoma hydrogen ma nā ʻaoʻao kūʻē o ka mokulele apo. Hoʻokumu kēia i kahi ʻano molekala ʻē aʻe, pinepine liʻiliʻi liʻiliʻi.

Ke alakaʻi nei kēia mau ʻokoʻa liʻiliʻi i nā ʻokoʻa koʻikoʻi i ke ʻano o ka launa ʻana o ka mole me nā mea honi ʻala, a no laila, kona ʻano ʻala.

2. Pākuʻi ma Natural vs. SyntheticMilk Lactone

Kumu Kūkākūkā maʻamau cis Isomer Proportion maʻamau trans Isomer Proportion Ke kumu

Kūlohelohe (mai ka dairy) > 99.5% (Effectively 100%) < 0.5% (Trace or absent) He stereospecific ke ala biosynthesis enzymatic i loko o ka bipi, e hana wale ana i ke ʻano (R) e alakaʻi i ka cis-lactone.

Synthetic ~70% - 95% ~5% - 30% ʻO ka hapa nui o nā ala hoʻohui kemika (e laʻa, mai nā petrochemical a i ʻole ricinoleic acid) ʻaʻole stereospecific kūpono, e hopena i ka hui ʻana o nā isomers (he racemate). ʻO ka lakio pololei e pili ana i ke kaʻina hana a me nā ʻanuʻu hoʻomaʻemaʻe.

3. Ka hopena naʻau: No ke aha he mea koʻikoʻi ka cis isomer

ʻAʻole kēia kaʻina isomer he ʻike kemika wale nō; he hopena pololei a ikaika i ka maikaʻi o ka sensory:

· cis-δ-Decalactone: ʻO kēia ka isomer me ka mea ʻala maikaʻi loa, ikaika, ʻaila, ʻano peach, a me ka ʻala waiu. ʻO ia ka hui ʻano-impact noMilk Lactone.

· trans-δ-Decalactone: ʻOi aku ka nāwaliwali o kēia isomer, ʻoi aku ka liʻiliʻi o ke ʻano, a i kekahi manawa he ʻala ʻōmaʻomaʻo a "momona". Hāʻawi liʻiliʻi loa ia i ka ʻaoʻao momona i makemake ʻia a hiki ke hoʻoheheʻe a hoʻololi paha i ka maʻemaʻe o ka ʻala.

4. Nā hopena no ka ʻoihana ʻala a me ka ʻala

ʻO ka māhele o cis i ka isomer trans kahi hōʻailona nui o ka maikaʻi a me ke kumukūʻai:

1. Nā Lactone Kūlohelohe (mai ka dairy): No ka mea he 100% cis, loaʻa iā lākou ka ʻala ʻoiaʻiʻo, ikaika, a makemake ʻia. ʻO lākou ke kumu kūʻai nui loa ma muli o ke kumukūʻai o ka ʻohi ʻana mai nā kumu waiu.

2. High-Quality Synthetic Lactones: Hoʻohana nā mea hana i nā ʻenehana kiʻekiʻe a i ʻole enzymatic no ka hoʻonui ʻana i ka hua o ka isomer cis (e laʻa, loaʻa ka 95%+). ʻO kahi COA no kahi lactone synthetic premium e kuhikuhi pinepine i kahi maʻiʻo cis kiʻekiʻe. He mea koʻikoʻi kēia e nānā nā mea kūʻai.

3. Nā Lactone Synthetic Maʻamau: Hōʻike ʻia kahi maʻiʻo cis haʻahaʻa (e laʻa, 70-85%) i kahi huahana liʻiliʻi. E loaʻa iā ia kahi ʻala nāwaliwali a emi ʻole ka ʻono a hoʻohana ʻia i nā noi kahi mea hoʻokele mua ke kumu kūʻai a ʻaʻole pono ka ʻala kiʻekiʻe.

Ka hopena

I ka hōʻuluʻuluʻana,ʻaʻole ka helu i helu paʻa akā he hōʻailona nui o ke kumu a me ka maikaʻi:

· Ma ke ʻano, ʻoi aku ka nui o ka haʻahaʻa i ka >99.5% cis-isomer.

· Ma ka synthesis, ʻokoʻa ka ʻāpana, akā ʻoi aku ka nui o ka cis-isomer maʻiʻo e hoʻopili pololei me kahi ʻala ʻala maikaʻi, kūlohelohe, a ʻoi aku ka ikaika.

No laila, i ka loiloi ʻana i kahi laʻana oMilk Lactone, ʻo ka cis / trans ratio kekahi o nā kikoʻī koʻikoʻi e nānā i ka palapala hōʻoia o ka ʻikepili (COA).
