I. Njira ya thupi ndi zofunikira pa kusungunuka kwa nkhanu
Kusungunuka kwa nkhanu ndi gawo lofunika kwambiri pakukula ndi chitukuko chawo. Pakukula kwa nkhanu, pamene matupi awo akukula, chipolopolo chakale chimalepheretsa kukula kwawo. Chifukwa chake, amafunika kusungunuka kuti apange chipolopolo chatsopano komanso chachikulu. Njirayi imafuna kugwiritsa ntchito mphamvu ndipo imafuna michere ina, monga mchere monga calcium ndi magnesium, zomwe zimagwiritsidwa ntchito popanga ndi kulimbitsa chipolopolo chatsopano; ndipo zinthu zina zomwe zimalimbikitsa kukula ndikuwongolera ntchito za thupi zimafunikanso kuti zitsimikizire kuti njira yosungunuka ikuyenda bwino.
DMTndi ligand yothandiza kwambiri yolandirira kukoma kwa m'madzi, yomwe imakhudza kwambiri kukoma ndi fungo la mitsempha ya nyama zam'madzi, motero imafulumizitsa liwiro la kudya kwa nyama zam'madzi ndikuwonjezera kudya kwawo pansi pa zovuta. Pakadali pano, DMT ili ndi mphamvu yofanana ndi kuumba, yokhala ndi ntchito yamphamvu yofanana ndi kuumba, yomwe imatha onjezerani liwiro la kusungunuka kwa shrimp ndi crab,makamaka pakati ndi kumapeto kwa ulimi wa nkhanu ndi nkhanu, zotsatira zake zimakhala zoonekeratu.
1. DMPT (Dimethyl-β-propiothetin)
Ntchito Zofunika Kwambiri
- Chokoka chakudya champhamvu: Chimalimbikitsa kwambiri chilakolako cha nsomba, nkhanu, nkhanu, ndi mitundu ina ya m'madzi, zomwe zimapangitsa kuti chakudya chizidya bwino.
- Kulimbikitsa kukula: Gulu lokhala ndi sulfure (—SCH₃) limathandizira kupanga mapuloteni, zomwe zimafulumizitsa kukula.
- Kukonza ubwino wa nyama: Kumachepetsa mafuta ochulukirapo ndipo kumawonjezera ma amino acid a umami (monga glutamic acid), kumawonjezera kukoma kwa nyama.
- Zotsatira zotsutsana ndi kupsinjika maganizo: Zimawonjezera kupirira ku zinthu zomwe zimawononga chilengedwe monga hypoxia ndi kusinthasintha kwa mchere.
Mitundu Yofunidwa
- Nsomba (monga carp, crucian carp, sea bass, large yellow croaker)
- Nsomba za mtundu wa Crustacean (monga nkhanu, shrimp, nkhanu)
- Nkhaka za m'nyanja ndi nkhono
Mlingo Wovomerezeka
- 50–200 mg/kg chakudya (sinthani kutengera mtundu ndi momwe madzi alili).
2. DMT (Dimethylthiazole)
Ntchito Zofunika Kwambiri
- Kukopa pang'ono kwa chakudya: Kumasonyeza zotsatira zokopa nsomba zina (monga nsomba za salmonids, nsomba za m'nyanja), ngakhale kuti ndi zofooka kuposa DMPT.
- Mphamvu zoletsa kuwononga ma oxidant: Kapangidwe ka thiazole kangathandize kuti chakudya chikhale cholimba kudzera mu ntchito yoletsa kuwononga ma oxidant.
- Zotsatira zomwe zingatheke pochiza mabakiteriya: Kafukufuku wina akusonyeza kuti zinthu zochokera ku thiazole zimaletsa matenda enaake.
Mitundu Yofunidwa
- Amagwiritsidwa ntchito makamaka podyetsa nsomba, makamaka za mitundu ya nsomba za m'madzi ozizira (monga nsomba ya salimoni, nsomba ya trout).
Mlingo Wovomerezeka
- 20–100 mg/kg chakudya (mlingo woyenera umafuna kutsimikiziridwa ndi mtundu wa nyama).
Kuyerekeza: DMPT vs. DMT
| Mbali | DMPT | DMT |
|---|---|---|
| Dzina la Mankhwala | Dimethyl-β-propiothetin | Dimethylthiazole |
| Udindo Waukulu | Chokopa chakudya, cholimbikitsa kukula | Wokongola pang'ono, woteteza ku matenda a antioxidant |
| Kugwira ntchito bwino | ★★★★★ (Wamphamvu) | ★★★☆☆ (Wocheperako) |
| Mitundu Yofunidwa | Nsomba, nkhanu, nkhanu, mollusks | Makamaka nsomba (monga salimoni, bass) |
| Mtengo | Zapamwamba | Pansi |
Malangizo Ogwiritsira Ntchito
- DMPT ndi yothandiza kwambiri koma yokwera mtengo; sankhani kutengera zosowa zaulimi.
- DMT imafuna kafukufuku wowonjezereka kuti mudziwe zotsatira za mitundu ina.
- Zonsezi zitha kuphatikizidwa ndi zowonjezera zina (monga amino acid, bile acids) kuti ziwonjezere magwiridwe antchito.
