Sebenzisa umshini wokupakisha we-vacuum isikhathi esingakanani sokudla okupakishiwe?

Hlala wethula izinzuzo zokusetshenziswa ekudleni, ukuze abantu abaningi bangabaze i-vacuum umshini wokupakisha Kungabekwa isikhathi esingakanani ngemuva kokupakisha i-vacuum, ukuthi ihambisana nokuphepha kokudla nokunye uchungechunge lwezinkinga. Umshini wokupakisha i-vacuum ungakhipha umoya ngokuzenzakalelayo ngaphakathi kwesikhwama, ukufeza inqubo ephelele yokuvala i-vacuum. Ubuchwepheshe bokupakisha i-vacuum baqala ngawo-1940. Ngo-1950, i-polyester, ifilimu yepulasitiki ye-polyethylene yasetshenziswa ngempumelelo ekupakisheni i-vacuum, kusukela ngaleso sikhathi, yafaka i-vacuum futhi yathuthuka ngokushesha. Umshini wokupakisha i-vacuum uvame ukusetshenziswa embonini yokudla, ngoba ngemuva kokupakisha i-vacuum, i-antioxidant yokudla, ukufeza injongo yokulondolozwa kwesikhathi eside. Inkinga ukuthi idinga ukudlula isivivinyo ukuze ithole imiphumela enembile. Njengoba sibonile impilo yeshelufu ekupakisheni kokudla, kuphela lapho ibhizinisi lisebenza khona ngemuva kokuhlolwa, lingakwazi ukwazi.

kodwa futhi kuwebhusayithi namuhla ukuqoqa imibuzo eminingi mayelana nokuphila kweshelufu lokudla lokupakisha nge-vacuum. Umshini wokupakisha nge-vacuum ozenzakalelayo ulungele ukusika inyama eqandisiwe, inyama ebandayo emisha, imikhiqizo yesoya efana nenyama, ukudla kwasolwandle, ukudla okulula, imikhiqizo yemithi, imishini yezokwelapha, izingxenye ze-elekthronikhi, amathuluzi ehadiwe imikhiqizo yemboni efana nokupakisha nge-vacuum noma igesi, ukupakisha sekuyindlela yokupakisha ukudla esikhathini esizayo. Ake sibheke ukuthi kufanele sazi ukuthi yini okufanele siyihloniphe. Izinhlobo zokuphila kweshelufu lokudla nokudla okuhlobene nokwelashwa nge-vacuum ngaphambi kokupakisha. Izinhlobo ezahlukene zokudla, noma inqubo ehlukile yokwelashwa ngaphambi kokupakisha, ukupakisha nge-vacuum kuhlukile ngemva kwesikhathi sokugcina ekamelweni lokushisa. { +- *} Ngokusekelwe kokuhlangenwe nakho, isibonelo, uma ukugcinwa kokudla ekamelweni lokushisa izinsuku ezimbili, kungase kube imikhiqizo yezolimo emisha noma imikhiqizo yenyama ecutshungulwe kancane. Uma kunjalo, ngemva kokupakisha nge-vacuum, kungandiswa kube izinsuku eziyisithupha. Ezinye zingandiswa zibe izinsuku ezingu-18. Isikhathi esihlala isikhathi eside isikhathi sokulethwa sifushane, izithelo ezomisiwe, ngisho nangaphezulu kwezinyanga ezingu-12. Kufanele senze ukuhlolwa komkhiqizo othize.

Okulandelayo kumayelana kakhulu nesimiso sokulondolozwa kokupakisha kwe-vacuum, ukuze kuqondwe inkinga yokuphila kweshalofu: ukusetshenziswa kokupakisha kwe-vacuum i-oxygen kuyimisebenzi eyinhloko yomshini wokupakisha we-vacuum, ukuze kuvinjelwe ukonakala kokudla, isimiso silula kakhulu. Ngenxa yokuthi ukonakala kokudla okubangelwa yi-microorganism, kanye ne-microorganisms eziningi (Njengokukhunta nemvubelo). Izidingo zokusinda kwe-oxygen, kanye nokupakisha kwe-vacuum ukusetshenziswa kwalesi simiso. Ukudla kwesikhwama kanye ne-oxygen emaseli kususiwe, i-microbe ilahlekelwe yiyo kanye nezinye izindawo zayo; 。 Imiphumela ikhombisa ukuthi lapho ukuhlushwa kwe-oxygen esikhwameni kungaphansi kuka-1%, ukukhula kwezinga lokuzala kwe-microbial kwehle kakhulu, ukuhlushwa kwe-oxygen & le; Kuze kube ngu-zero. 5%, iningi le-microorganisms liyavinjelwa, yeka ukuzala. Qaphela: ukupakisha kwe-vacuum kungavimbela ukuzala kwe-anaerobic bacteria kanye nokusabela kwe-enzyme okubangelwa ukushintsha kombala kokudla, ngokuqandisa, ukuqandisa, ukomisa, ukubulala amagciwane okushisa okuphezulu, ukubulala amagciwane ngemisebe, ukubulala amagciwane nge-microwave, usawoti kanye nezinye izindlela ezisizayo. Ukuhlanza nge-vacuum akugcini nje ngokuvimbela ukukhula kokuzalana kwamagciwane, omunye umsebenzi obalulekile ukuvimbela ukungcola kokudla, ngoba ukudla okunamafutha kuqukethe ama-fatty acid amaningi angagcwele, ukungcola nge-oxygen, kwenza ukunambitheka kokudla kuguquke. Ngaphezu kwalokho, ukungcola kwenza futhi uvithamini A kanye ne-vitamin C kulahleke, umbala wokudla ungazinzile ngaphansi kwethonya le-oxygen, kwenza umbala ube mnyama. I-oxygen ingavimbela ngempumelelo ukonakala kokudla, ngakho-ke, igcina umbala wayo, iphunga, ukunambitheka kanye nenani lokudla okunempilo. Uma nje ingafinyelela izinga elithile le-vacuum, umphumela uyafana.

Akudingeki ukuthi ukukuthola kubize kakhulu, kuthathe isikhathi, noma kube nzima. Konke kuncike endleleni efanele kanye ne-checkweigher esikalini esikhona.

Wonke amasu esikhathi eside kanye nezenzo zesikhathi esifushane ze-Smart Weight zizobunjwa yiqoqo lezindinganiso eziyinhloko ezabelwana ngazo yilowo nalowo osebenzisana naye.

Isisindo sithengiswa emakethe ye-oversees futhi sinedumela elihle. Ngaphandle kwalokho, imikhiqizo yethu ithengiswa ngamanani afanele.
