Ntchito:
1.Undecanoic acid ndi wamba mpweya chromatography mkati muyezo pawiri, capillary mpweya chromatography mkati muyezo njira ntchito kudziwa preservatives dehydroacetic asidi, asidi benzoic ndi asidi sorbic mu chakudya, chitsanzo kuchira mlingo anali pakati pa 96% ndi 104%, ndi Kugwirizana kwa mzere wokhazikika kunali kwabwino, kokwanira kwa kusiyanasiyana kwa kutsimikiza kwachitsanzo kunali kochepa, dehydroacetic acid anali 0.71%, benzoic acid anali 0.82% ndi sorbic acid anali 0.62%. Ndi yosavuta, yachangu komanso yolondola. Kuphatikiza pa izi, itha kugwiritsidwanso ntchito kudziwa zomwe zili muzakudya zosiyanasiyana [5-7].
2. Amagwiritsidwa ntchito popanga zowonjezera zakudya zomwe zimakhala ndi ma organic acid ndi mafuta apakatikati, omwe amagwiritsidwa ntchito poyesa mafuta apakati apakati (caprylic acid kapena nonanoic acid) ndi ma organic acid (citric acid) okhala ndi antibacterial zochita zambiri. pochiza mitundu yosiyanasiyana ndi ma MCFA ndi ma OA osiyanasiyana, ndikufananiza ziwirizo mu chiŵerengero choyenera kuti zikhale ndi mphamvu yogwirizana, kuti zitsimikizire kuti antibacterial zotsatira zitha kukhala zamphamvu pamaziko a kuchepetsa mlingo wa sing'anga-unyolo mafuta zidulo ndi organic zidulo [8].
3.Undecanoic acid imagwiritsidwa ntchito popanga organic synthesis komanso ngati chowongolera pulasitiki.
