Ra'ayi da aiki

Marufi na Vacuum kunshin ne wanda ke kare samfura daga gurɓacewar muhalli kuma yana tsawaita rayuwar abinci, wanda zai iya haɓaka ƙima da ingancin samfuran. Fasahar fakitin Vacuum ta samo asali ne a cikin 1940s. Tun da polyester da polyethylene fina-finai na filastik an yi nasarar amfani da su a cikin marufi na kayayyaki a cikin 1950, injunan marufi sun haɓaka cikin sauri.

A fagen rayuwa da aikin mutane, ana iya samun kowane nau'in marufi na filastik ko'ina. Nauyi mai sauƙi, mai da iska, sabo mai kiyayewa, lalatawa, da fakitin robobi na hana tsatsa ya rufe fage da yawa daga abinci zuwa magani, saƙa, daga masana'anta na daidaici zuwa masana'antar sarrafa ƙarfe da dakunan gwaje-gwaje. Ƙara faɗaɗa aikace-aikacen marufi na filastik ya haɓaka haɓaka injinan tattara kayan injin filastik kuma ya gabatar da buƙatu mafi girma a gare su.

Tsarin marufi: manufar ita ce don rage iskar oxygen a cikin kunshin, hana kyawu da lalacewar kayan abinci da aka tattara, kula da launi da ƙamshin abinci, da tsawaita rayuwar shiryayye.

Babban aikin marufi shine cire iskar oxygen don taimakawa hana abinci daga lalacewa. Ka'idar ta kasance mai sauƙi, saboda lalacewar abinci galibi ana haifar da shi ta hanyar ayyukan ƙwayoyin cuta, kuma rayuwar mafi yawan ƙwayoyin cuta (kamar mold da yisti) na buƙatar iskar oxygen. Ee, kuma vacuum packaging yana amfani da wannan ka'ida don fitar da iskar oxygen a cikin Jakar Marufi da ƙwayoyin abinci, ta yadda ƙananan abubuwa su rasa "yanayin rayuwa". Gwaje-gwaje sun tabbatar da cewa: lokacin da iskar oxygen a cikin jakar marufi ya kasance ≤1%, saurin girma da haifuwa na ƙwayoyin cuta za su ragu sosai, kuma lokacin da iskar oxygen ta kasance ≤0.5%, yawancin ƙwayoyin cuta za a hana su kuma daina kiwo. (Lura: Marufi ba zai iya hana ci gaban kwayoyin anaerobic da lalacewar abinci da canza launin da ke haifar da halayen enzyme ba, don haka yana buƙatar haɗa shi tare da wasu hanyoyin taimako, kamar firiji, daskarewa mai sauri, bushewa, haifuwa mai zafi mai zafi, haifuwar radiation, haifuwar microwave, pickled gishiri da sauransu).

Baya ga hana girma da haifuwa na ƙananan ƙwayoyin cuta, vacuum deoxygenation yana da wani muhimmin aiki don hana iskar oxygen da abinci. Saboda abinci mai mai ya ƙunshi adadi mai yawa na fatty acids, suna yin oxidized ta hanyar iskar oxygen, suna sa abinci dandano da lalacewa. Bugu da ƙari, oxidation kuma yana sa abinci asarar bitamin A da C, abubuwan da ba su da kyau a cikin launin abinci suna shafar oxygen, suna sa launi ya yi duhu. Sabili da haka, cirewar iskar oxygen zai iya hana abinci yadda ya kamata daga lalacewa da kuma kula da launi, ƙanshi, dandano da ƙimar abinci mai gina jiki.

Babban aikin buɗaɗɗen iska mai cike da iska ba kawai aikin kiyaye iskar oxygen ba ne, har ma da aikin anti-matsa lamba, toshewar iska da sabo. Zai iya kiyaye launi na asali yadda ya kamata, kamshi, dandano, siffar da ingancin abinci na dogon lokaci. darajar abinci mai gina jiki. Bugu da ƙari, yawancin abinci ba su dace da marufi ba amma dole ne a cika su tare da hauhawar farashin kaya. Irin su crispy da m abinci, abincin da ke da sauƙi don haɓakawa, abincin da ke da sauƙi ga lalacewa da rasa mai, abinci mai kaifi ko taurin gaske wanda zai huda jakar marufi, da dai sauransu. shafi bayyanar da bugu kayan ado na marufi jakar.

Marufi mai cike da iska yana cike da nitrogen, carbon dioxide, iskar oxygen guda ɗaya ko cakuda iskar gas biyu ko uku bayan injin. Gas na nitrogen iskar gas ce mara aiki, wanda ke aiki azaman cikawa don kula da matsi mai kyau a cikin jakar don hana iskan da ke wajen jakar shiga cikin jakar da kuma kare abinci. Nitrogen dioxide na iya narkewa cikin sauƙi a cikin kitse ko ruwa, kuma hasken carbonic acid da wannan narkewar ya haifar yana hana wasu ƙwayoyin cuta kamar mold da ƙwayoyin cuta masu lalacewa. Iskar oxygen nata na iya hana girma da haifuwar kwayoyin cutar anaerobic, kiyaye 'ya'yan itatuwa da kayan marmari masu kyau da launuka, kuma yawan iskar oxygen na iya kiyaye sabo nama mai haske ja. A freshness na 'ya'yan itatuwa da kayan lambu ba ya rasa abinci mai gina jiki.
