Izi zimalowa mu mikhalidwe yeniyeni ya mankhwala yomwe imafotokoza ubwino ndi khalidwe la Milk Lactone.
Nayi kusanthula kwatsatanetsatane:
1. Chemistry: Chifukwa Chake Isomerism Ndi Yofunika mu Lactones
Pa ma lactone monga δ-Decalactone, mawu akuti “cis” ndi “trans” sakutanthauza mgwirizano wapawiri (monga momwe zimakhalira m'mamolekyu monga mafuta acids) koma amatanthauza stereochemistry yogwirizana pa malo awiri a chiral pa mphete. Kapangidwe ka mphete kamapanga mkhalidwe womwe malo ozungulira maatomu a haidrojeni ndi unyolo wa alkyl poyerekeza ndi ndege ya mphete zimasiyana.
· cis-Isomer: Maatomu a haidrojeni omwe ali pa maatomu a kaboni oyenerera ali mbali imodzi ya mphete. Izi zimapanga mawonekedwe enieni komanso oletsedwa.
· Trans-Isomer: Maatomu a haidrojeni ali mbali zosiyana za mphete. Izi zimapanga mawonekedwe osiyana, nthawi zambiri osapanikizika, a molekyulu.
Kusiyana kochepa kumeneku kwa mawonekedwe kumabweretsa kusiyana kwakukulu kwa momwe molekyulu imagwirira ntchito ndi zolandirira fungo, motero, mawonekedwe ake a fungo.
2. Kuchuluka kwa Zachilengedwe vs. KupangaLaktoni ya Mkaka
Gwero la Cis Yodziwika bwino Isomer Proportion Yodziwika bwino ya Trans Isomer Proportion Chifukwa Chachikulu
Zachilengedwe (zochokera ku mkaka) > 99.5% (Zogwira ntchito 100%) < 0.5% (Zotsalira kapena palibe) Njira ya enzyme biosynthesis mu ng'ombe ndi yosiyana, imapanga mawonekedwe a (R) okha omwe amatsogolera ku cis-lactone.
Zopangidwa ~70% – 95% ~5% – 30% Njira zambiri zopangira mankhwala (monga, kuchokera ku petrochemicals kapena ricinoleic acid) sizili za stereospecific mokwanira, zomwe zimapangitsa kuti pakhale chisakanizo cha isomers (racemate). Chiŵerengero chenicheni chimadalira njira yeniyeni ndi njira zoyeretsera.
3. Kukhudza Maganizo: Chifukwa Chake Cis Isomer Ndi Yofunika Kwambiri
Chiwerengero cha isomer ichi sichinthu chongofuna kudziwa za mankhwala okha, koma chimakhudza mwachindunji komanso mwamphamvu khalidwe la kumva:
· cis-δ-Decalactone: Iyi ndi isomer yokhala ndi fungo lamtengo wapatali, lokoma, lofanana ndi pichesi, komanso la mkaka. Ndi chinthu chomwe chimapangitsa kuti munthu azitha kusiyanitsa ndi ena.Lactone ya Mkaka.
· trans-δ-Decalactone: Isomer iyi ili ndi fungo lofooka kwambiri, losaoneka bwino, ndipo nthawi zina ngakhale "lobiriwira" kapena "lamafuta". Silipereka zambiri pa mawonekedwe okoma omwe mukufuna ndipo lingathe kuchepetsa kapena kusokoneza kuyera kwa fungo.
4. Zotsatira zake pa Makampani Opanga Zokometsera ndi Zonunkira
Chiŵerengero cha cis ndi trans isomer ndi chizindikiro chachikulu cha khalidwe ndi mtengo:
1. Ma Lactone Achilengedwe (ochokera ku Dairy): Popeza ndi 100% cis, ali ndi fungo lenileni, lamphamvu, komanso lofunika kwambiri. Ndiwonso okwera mtengo kwambiri chifukwa cha njira yokwera mtengo yochotsera mkaka kuchokera kuzinthu za mkaka.
2. Ma Lactone Opangidwa Abwino Kwambiri: Opanga amagwiritsa ntchito njira zamakono zamakemikolo kapena ma enzyme kuti achulukitse phindu la cis isomer (monga, kufika 95%+). COA ya lactone yopangidwa yapamwamba nthawi zambiri imafotokoza kuchuluka kwa cis. Ichi ndi chizindikiro chofunikira chomwe ogula amachiyang'ana.
3. Ma Lactone Opangidwa Mwachizolowezi: Kuchuluka kwa cis kochepa (mwachitsanzo, 70-85%) kumasonyeza kuti sichinakonzedwe bwino kwenikweni. Chidzakhala ndi fungo lofooka, losamveka bwino ndipo chimagwiritsidwa ntchito m'malo omwe mtengo wake ndi wofunikira kwambiri ndipo fungo labwino kwambiri silili lofunikira.
Mapeto
Mwachidule, chiwerengerocho si nambala yokhazikika koma chizindikiro chachikulu cha chiyambi ndi khalidwe:
· Mwachilengedwe, chiwerengerochi chimasokonekera kwambiri kufika pa >99.5% cis-isomer.
· Mu kapangidwe kake, chiwerengerocho chimasiyana, koma kuchuluka kwa cis-isomer kwambiri kumagwirizana mwachindunji ndi fungo labwino kwambiri, lachilengedwe, komanso lokoma kwambiri.
Chifukwa chake, poyesa chitsanzo chaLaktoni ya Mkaka, chiŵerengero cha cis/trans ndi chimodzi mwa zinthu zofunika kwambiri kuziwunikanso pa Satifiketi Yowunikira (COA).
