Taupānga:
1.Ko te waikawa Undecanoic he chromatography hau noa i roto i te pūhui paerewa o roto, i whakamahia te tikanga paerewa a-roto hau hau kaporeihana ki te whakatau i nga kaitiaki o te waikawa dehydroacetic, te waikawa benzoic me te waikawa sorbic i roto i te kai, ko te tere whakaora tauira i waenga i te 96% me te 104%, te he pai te hononga raina paerewa, he iti te whakarea o te rereketanga o te whakatau tauira, he 0.71% te waikawa dehydroacetic, he 0.82% te waikawa benzoic me te 0.62%.He maamaa, he tere me te tika.I tua atu i tenei, ka taea hoki te whakamahi ki te whakatau i te ihirangi o nga momo rongoa i roto i te kai [5-7].
2. Ka whakamahia i roto i te hanga o nga taapiri kai kei roto nga waikawa waro me nga waikawa ngako mekameka-waewae, e whakamahia ana hei tirotiro i nga waikawa ngako mekameka-waewae (waikawa caprylic, waikawa nonanoic ranei) me nga waikawa waro (waikawa citric) me te nui atu o nga mahi antibacterial. na roto i te rongoa i nga riaka rereke me nga MCFA me nga OA rereke, katahi ka whakataurite i nga mea e rua i roto i te tauwehenga e tika ana kia kaha ake ai te mahi tahi, kia kaha ake ai te kaha antibacterial i runga i te whakaiti i te horopeta o te mekameka-waewae. waikawa ngako me te waikawa waro [8].
3.Ka whakamahia te waikawa Undecanoic i roto i te whakahiatotanga pararopi me te mea he kaiwhakahaere kirihou.
