Pisinisi Faʻapapuina o meaʻai e faʻasino i se tulaga sili ona faʻamamaina o loʻo i ai se mea e mafai ona maua ai le faʻaaogaina o le vevela o le vevela. O le faʻatau atu o le faʻapitofia o meaʻai na maua ai meaʻai i meaʻai o loʻo faʻaalia e le Scrobulign, e leai ni BarthoGenic micrononicms, ae leai ni meaola e mafai ona faʻateleina i le vevela vevela.
Ina ia mafai ona ausia tulaga taugofie, o le mafai ona aofia ai faʻamatalaga o loʻo aofia ai faiga poʻo mea e faamautu ai, ma faʻamamaina lelei, ma le afifiina lelei. O tagata gaosi ia sili atu i le faʻalauteleina o le gaosiga o tekonolosi ma sili atu le maualuga o manaʻoga faʻatonutonu e sili atu tulaga lavelave ma atoatoa gaosi gaioiga.
O le tala faʻatauvaʻa e aoina ai tekonolosi i faʻatekinolosi o meaʻai, ma le faʻailoga aloaia o lenei faiga o le faʻaaogaina lelei o lenei tekonolosi e faʻatino ai le mautinoa o le saogalemu o meaai. O le faʻapitoa faʻagasologa o le faʻaaogaina o pisinisi faʻafefeteina asiasiga i meaʻai o le Microbiological Accouctiction o loʻo mulimuli mai (o nisi sili atu manoa tolu-pati o le vasega
1. Canted Bactertal aganuu
O le faʻaaogaina o le coctorial aganuu o se tasi lea o taua gaioiga o loʻo i totonu o le faʻatau atu faʻapito le asiasiga o meaʻai gaosi. E ala i le faʻamalositinoga faʻamalosi o mea i totonu o faʻataʻitaʻiga o faʻataʻitaʻiga, ma le suʻesuʻeina ma le siakiina o le aganuʻu masani, o le miligibbal vaega i meaʻai gaosi e mafai ona iloiloina.
Masani o pathogenic microornicsms i mafai ona aofia ai ae le gata i le urrmophilic bactersia, pei o le bacilus stearawouths, bestridium gecchaltus Mesophilic Anaerobic Bacteria, pei o BOOLINUNUM TOXIN SPRSTRIIDRIIDIMY, CLSTSTRIMP STRESEL, CLESSTRIDIH ARHURICUMUMUSH, THECTRRID Mesophilic Aerrobic Bactersia, pei o BacIlus Spiptilis, Baclulus Cereus, etc.; E le o le mafai ona gaosia o siama e pei o Escheroiso Coli, SLeptoococus, le ausae ma le mald, vevela-tetee i luga. A o le i faia le faʻapipiʻiina o le vaega o le paleni, ia mautinoa e fuaina le pH o le mafai ona filifilia le talafeagai auala.
2. Sampling o le tofotofoga mea
O le faʻatulagaina auala e masani ona faʻaaogaina mo le faʻataʻitaʻiina o faʻataʻitaʻiga mea o meaʻai toto. Ina ua faʻataʻitaʻiina ni vaega tetele o meaʻai taumafa, simpling e pei ona faʻaau mai i isi itu e pei o le gaosiga, faʻailoga, ituaiga o meaʻai gaosi poʻo le gaosiga taimi. Mo mea le mautonu e pei o le aufaitino e pei o apaʻau o apaʻau, nifo, ma le puao i le faʻasalalauina o faʻatauga ma faletamaoti, e masani ona faʻatinoina e tusa ma le tulaga. O le faavae faʻavae mo le faʻataʻitaʻiina o mea faʻataʻitaʻi e filifili ai le metotia talafeagai e tusa ai ma le tulaga moni, ina ia mafai ona maua le tulaga o meaʻai.
3. Faasao Faapitoa
Talu ai ma le faʻataʻitaʻiga o loʻo iai ni faʻafitauli, faʻagaioiga e pei o mamafa, tausia o le mafanafana, ma le tatalaina metotia e manaʻomia. Ia fuaina le 'upega tafaʻilagi o le a faʻaaogaina, e faʻalagolago i le ituaiga o mafai, e manaʻomia ona saʻo e 1G poʻo le 2g. Tuʻufaʻatasia ma le ph ma le vevela, o loʻo teu pea vai i le vevela tumau mo le 10 aso; o le gaʻo e gaʻo pe le lavalava i le taimi o le faʻagasologa e tatau ona pikiina vave mo le aʻoaʻoina. Ina ua maeʻa le vevela o le Science Provenages, tuu le apa o le potu vevela mo le le aʻoga a le Aseppec. A maeʻa ona amata le mafai, faʻaaoga mea faigaluega talafeagai e ave muamua ai le 10-20 mg o le mea muamua i se setete tulaga ese, faʻaliliu i totonu o le koneteina.
4.Maualalo acid meaai
O le galueaina o meaʻai maualalo-acid e manaʻomia metotia faʻapitoa: atiaʻeina o bromptassium viple broth broth i le 36 ° c, ma le galueaina o le kuka mama i le 55 c. O faʻaiuga e manogi ma le pi ma le lelei, ma e sili atu saʻo suʻesuʻega o loʻo faʻatulagaina pe a maeʻa le tulaga o le siama o le siama o le siama. When culturing in the medium, focus on observing the acid production and gas production of the microbial colonies on the medium, as well as the appearance and color of the colonies, so as to confirm the specific microbial species in the food.
5. Microscopic Iloiloga
O le suʻega Scrosscopic o le suʻega e sili ona faʻaaogaina muamua suʻega o le suʻega mo suʻega faʻapisinisi I totonu o se siosiomaga faigofie, ma faʻaaoga ai le faʻagaioiga a setologiga, ona faʻaititia le vai inu o le microfilionis i totonu o faʻataʻitaʻiga, ma matauina le foliga mai o le gaʻo i totonu o le siama i totonu o le siama i totonu o le gaʻo. Faʻaiseina, ma faʻatulaga le isi meaalofa o le faʻafouina o le aganuu ma faʻailoga ia atili ai ona faʻamaonia ai le ituaiga o siama o loʻo iai i le apa. O lenei sitepu e manaʻomia ai le maualuga maualuga tomai faʻapitoa o tagata asiasi, ma ua avea foi ma fesoʻotaʻiga e mafai ona sili faʻataʻitaʻi le poto faʻataʻitaʻi poto ma tomai a tagata asiasi.
6. Galueaina suʻega mo meaʻai a le Acadic ma PH i lalo ole 4.6
Mo meaʻai a le Acadic ma le PH taua maualalo i lalo ifo o le 4.6, o le meaʻai o meaʻai siama e masani ona le toe manaʻomia. I le militeli tulaga faʻapitoa, faʻaopopo i le faʻaaogaina o le acidic micros mea o le auala, e manaʻomia foʻi le faʻaaogaina o le malt o le vaituloto. E ala i le amoina o kocroscoic o le aganuu masani, o siama o siama i oloa acid, ina ia mafai ai ona faia se isi mea faigaluega.
