Daim ntawv thov Ingenious ntawm tshiab pub additives-Glycerol Monolaurate hauv aquaculture

Nyob rau hauv xyoo tas los no, glycerides ntawm MCFA, uas yog ib hom tshiab pub additive, tau txais kev saib xyuas zoo vim lawv cov kab mob ua tau zoo thiab muaj txiaj ntsig zoo rau cov hnyuv.Glycerol monolaurate (GML) yog ib qho khoom noj khoom haus MCFA monoester uas muaj nyob rau hauv cov kua mis thiab cov txiv maj phaub roj. FDA tau pom zoo tias nws feem ntau suav tias muaj kev nyab xeeb thaum siv ntau npaum li 10 txog 2000mg / kg hauv ntau yam khoom. Ntxiv nrog rau nws cov tshuaj tua kab mob thiab tshuaj tua kab mob, nws kuj muaj emulsifying zog.

Glycerol Monolaurate(CASNo:142-18-7 ib)

 Lub npe:Glycerol Monolaurate

Lwm lub npe:Monolaurin los yog GML

 Formula:C₁₅H₃₀O₄

molecular hnyav:274.21 Nws

solubility:Me ntsis soluble hauv dejthiab glycerol,Soluble hauv methanol, ethano

Qhov tshwm sim:Dawb los yog lub teeb daj khoom

GML muaj peev xwm nyob twj ywm rau hauv lub plab zom mov kom ntev dua thiab txhim kho txoj hnyuv, uas txhais tau hais tias GML tuaj yeem cuam tshuam ncaj qha rau lub plab microbiome, pab lub cev sau cov as-ham uas tsis tuaj yeem nqus tau thiab thaum kawg ua kom lub cev muaj peev xwm nqus tau lub zog.

Txog rau tam sim no, kev loj hlob txhawb nqa thiab kev tiv thaiv kab mob ntawm monoglycerides hauv cov nqaij qaib tau raug tshawb fawb tob los txhim kho lub qe qe, noj efficiency, qe tshiab zoo thiab khoom noj muaj txiaj ntsig ntawm nqaij qaib. Tsis tas li ntawd, GML kuj tseem muaj kev txhawb nqa kev noj qab haus huv nrog rau cov haujlwm muaj zog tiv thaiv kab mob thiab tshuaj tua kab mob.

Cov teebmeem ntawm pub monoglyceride ntawm laurate (GML) ntawm kev loj hlob kev ua tau zoo, digestive enzymes, lub cev muaj pes tsawg leeg thiab tsis muaj kev tiv thaiv kab mob ntawm Litopenaeus vannamei

2. Cov cw siv hauv txoj kev tshawb fawb tau pub nrog plaub qhov sib txawv, nrog rau 0, 350, 700 thiab 1050mg / kg GML ntxiv rau cov khoom noj raws li. Qhov kev sim tau siv sijhawm 60 hnub.

Cov txiaj ntsig kev tshawb fawb pom tau tias GML 700 thiab 1050 mg / kg tau txhim kho kev loj hlob, kev ua haujlwm ntawm plab hnyuv lipase thiab protease, thaum ntxiv ntawm GML 1050 mg / kg rau kev noj zaub mov ua rau cov ntshav lipids thiab cov lipids hauv lub cev.

Cov kev ua ub no ntawm plab hnyuv lipase thiab protease tau pom muaj kev nce ntxiv nrog kev hloov pauv ntawm GML qib, thiab GML pawg hauv 700 thiab 1050 mg / kg koob tshuaj ntau dua li pawg tswj hwm (P <0.05). Lub caij no, cov qib sib txawv ntawm GML tsis muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ntawm digestive enzymes hauv hepatopancreas.

Tsis tas li ntawd, thaum GML ntxiv rau cov khoom noj ntawm qhov ntau ntawm 350 thiab 700mg / kg, nws txhim kho kev tiv thaiv ntawm cws los ntawm kev txhim kho lawv cov tshuaj tua kab mob antioxidant thiab cov kab mob.

Lub peev xwm ntawm qis GML raws li cov khoom noj ntxiv los txhim kho txoj kev loj hlob, kev zom zaub mov enzyme thiab tsis muaj kev tiv thaiv kab mob ntawm cov cw dawb. Raws li kev tshawb fawb tau pom, vim muaj kev ua ub no ntawm plab hnyuv lipase thiab protease, pub ntxiv koob tshuaj ntawm 700 thiab 1050 mg / kg GML tau txhim kho kev loj hlob ntawm cov cw dawb los ntawm South America.
