Ibhegi yokufunxaukongeza ekuvimbeleni ukukhula kunye nokuveliswa kwee-microorganisms, omnye umsebenzi obalulekileyo kukuthintela i-oxidation yokutya, kuba ukutya kweoli kunye negrisi kuqulethe inani elikhulu lee-acids ezinamafutha angaxutywanga, indima ye-oksijini kunye ne-oxidation, ukwenzela ukuba ukutya kukubi, ukuwohloka, ukongezelela, i-oxidation ye-vitamin A kunye no-C ilahleko, umbala wokutya kwindima yezinto ezingazinzanga yi-oksijini, ukuze umbala ube mnyama.Ke ngoko, ukususwa kweoksijini kunokuthintela ngokufanelekileyo ukuwohloka kokutya kunye nokugcina umbala, ivumba, incasa kunye nexabiso lesondlo.
Ibhegi yokufunxakukukhusela iimveliso kungcoliseko lokusingqongileyo kunye nokwandisa ixesha leshelufu lokutya kunye nokunye ukupakishwa, kunokuphucula ixabiso kunye nomgangatho weemveliso.Itekhnoloji yokupakisha ivacuum yaqala ngeminyaka yoo-1940.Ukusukela ngo-1950, i-polyester, ifilimu yeplastiki ye-polyethylene ifakwe ngempumelelo kwipakethe yempahla,umatshini wokupakisha wevacuumiphuhliswe ngokukhawuleza.
Kwintsimi yobomi kunye nomsebenzi wabantu, kukho iindidi ezininzi zengxowa yokufunxa.Ikhaphukhaphu, itywiniweyo, intsha, ichasene nomhlwa, ukupakishwa kwevacuum yobungqina bokuhlwa kuyo yonke into yokutya ukuya kumachiza, iimveliso ezinithiweyo, ukusuka kwimveliso echanekileyo ukuya kwimveliso yesinyithi kunye neelebhu kunye neminye imimandla emininzi.Ukusetyenziswa okukhulayo kokupakishwa kwevacuum kuye kwaqhuba uphuhliso lweoomatshini bokupakisha bevacuum, kwaye ukwabeke phambili iimfuno eziphezulu kubo.
