Kugwiritsa Ntchito Mwanzeru Zowonjezera Zakudya Zatsopano - Glycerol Monolaurate mu Ulimi wa Zinyama

M'zaka zaposachedwa, ma glycerides a MCFA, monga mtundu watsopano wa zowonjezera zakudya, alandiridwa kwambiri chifukwa cha mphamvu zawo zoletsa mabakiteriya komanso zotsatira zabwino pa thanzi la m'mimba.Glycerol monolaurate (GML) ndi monoester ya MCFA yopatsa thanzi yomwe imapezeka mu mkaka wa m'mawere ndi mafuta a kokonati. FDA yavomereza kuti nthawi zambiri imaonedwa kuti ndi yotetezeka ikagwiritsidwa ntchito pa mlingo wa 10 mpaka 2000mg/kg m'zinthu zosiyanasiyana. Kuwonjezera pa mphamvu zake zotsutsana ndi mabakiteriya komanso mavairasi, ilinso ndi mphamvu zopanga emulsifying.

GML imatha kukhalabe m'mimba kwa nthawi yayitali ndikukonza matumbo, zomwe zikutanthauza kuti GML imatha kukhudza mwachindunji microbiome ya m'mimba, kuthandiza thupi kusonkhanitsa michere yomwe singalowe m'thupi ndikuwonjezera mphamvu ya thupi yoyamwa mphamvu.

Mpaka pano, zotsatira za monoglycerides zomwe zimakulitsa kukula ndi kusintha chitetezo cha mthupi mu nkhuku zaphunziridwa mozama kuti ziwonjezere kuchuluka kwa mazira omwe amapangidwa, kugwiritsa ntchito bwino chakudya, ubwino wa mazira atsopano komanso kufunika kwa zakudya m'nkhuku. Kuphatikiza apo, GML imakhalanso ndi mphamvu yolimbikitsa thanzi komanso mphamvu zotsutsana ndi kutupa komanso mabakiteriya.

Zotsatira za feed monoglyceride ya laurate (GML) pa kukula kwa thupi, ma enzymes am'mimba, kapangidwe ka thupi komanso chitetezo chamthupi chosagwirizana ndi Litopenaeus vannamei.

2. Nsomba zomwe zinagwiritsidwa ntchito mu kafukufukuyu zinadyetsedwa ndi zakudya zinayi zosiyana, ndipo 0, 350, 700 ndi 1050mg/kg GML zinawonjezeredwa ku zakudyazo motsatana. Kuyeseraku kunatenga masiku 60.

Zotsatira za kafukufukuyu zikusonyeza kuti GML 700 ndi 1050 mg/kg zimathandizira kwambiri kukula, ntchito za lipase ndi protease m'matumbo, pomwe kuwonjezera GML 1050 mg/kg pazakudya kumawonjezera mafuta m'magazi ndi mafuta osaphika m'thupi.

Ntchito za lipase ndi protease m'matumbo zinasonyeza kuwonjezeka kwa kuchuluka kwa GML, ndipo magulu a GML m'magulu a 700 ndi 1050 mg/kg anali okwera kwambiri kuposa gulu lolamulira (P < 0.05). Pakadali pano, kuchuluka kosiyanasiyana kwa GML sikunakhudze kwambiri ntchito ya ma enzymes ogaya chakudya m'thupi la chiwindi.

Kuphatikiza apo, pamene GML yowonjezeredwa ku chakudya pamlingo wa 350 ndi 700mg/kg, imawonjezera chitetezo cha mthupi cha nkhanu mwa kukweza mphamvu yawo yolimbana ndi ma antioxidants ndi mabakiteriya.

Kuthekera kwa GML yochepa ngati chowonjezera cha chakudya kuti chiwongolere kukula, ntchito ya ma enzyme m'mimba komanso chitetezo chamthupi cha nkhanu zoyera. Malinga ndi zotsatira za kafukufukuyu, chifukwa cha kuchuluka kwa ntchito za lipase ndi protease m'matumbo, kuchuluka kwa 700 ndi 1050 mg/kg kwa GML kunathandiza kwambiri kukula kwa nkhanu zoyera zochokera ku South America.
