Zvokudya zvakapfuma muprotein, makhahydrates uye mafuta anovaka muviri, pasi pechiito chemuviri, makemikari uye zvipenyu zvinhu, zvicharasikirwa nemuvara wepakutanga, kunhuhwirira, kuravira, chimiro uye kuora, pakati peiyo basa rezvipembenene zvinokuvadza ndicho chikonzero chikuru chekuora kwezvokudya uye kuora.
Pamberi pemaindasitiri, vanhu vaiwanzoshandisa nzira dzechinyakare dzakadai sekuomesa, salting, shuga, kuvirisa kuchengetedza chikafu. Nekuvandudzwa kweindasitiri yechikafu yemazuva ano, vanhu vane matekinoroji matsva ekuchengetedza chikafu, senge canning, vacuum packaging, pneumatic conditioning packaging uye dzimwe nzira dzekurongedza, asi zvakare kushandiswa kweakasiyana siyana tekinoroji yesterilization, senge autoclaving, irradiation sterilization, electron beam sterilization, chengetedzo uye dzimwe nzira dzefiriji.
Zvisinei, zvisinei kuti teknolojia ipi inoshandiswa, haisi benzi, saka kune zvakawanda zvekudya, kushandiswa kwezvidziviriro semutsara wechipiri wekudzivirira kuchengetedza mararamiro ezvokudya zvakanyanya kukosha.
Lactic acid (lactic acid) ndiyo sodium munyu welactic acid. Chigadzirwa chacho hachina ruvara kana zvishoma yero inoonekera mvura, haina kunhuwa, ine munyu zvishoma inovava kuravira, yakasanganiswa mumvura, ethanol, glycerin.
Muindasitiri yezvekudya, inonyanya kushandiswa seanonhuhwirira agent, acidity regulator uye humectant. Nekuti sodium lactate ine mhedzisiro yekudzikisa basa remvura rekudya, inogona kuwedzera hupenyu hwesherufu yechikafu, uye inoshandiswa sechikafu chekuchengetedza kuchengetedza zvigadzirwa zvenyama.
Kuchengetedza nzira ye lactic acid uye sodium lactate
Kazhinji, iyo yakakwirira yezvinyorwa zve organic acids mune iyo isina-dissociated state, iyo inosimba antibacterial kugona (nekuti organic acids mune isina-dissociated state inoyambuka nyore bacterial cell membrane uye kupinda musero muviri), iyo bhakitiriya clearance yelactate ions (H) kubva musero inoshandisa simba, inoderedza sero metabolism, uye nokudaro inotadzisa kukura kwebhakitiriya.
Iyo inochengetedza maitiro e sodium lactate ine nheyo mbiri: 1. Kuwedzerwa kwe sodium lactate kunogona kuderedza basa remvura rechigadzirwa, nokudaro kudzivirira kukura kwe microorganisms. 2. Lactate ion ine antibacterial functional group. Lactic acid pachayo ine yakakosha inhibitory mhedzisiro pakukura uye kubereka kwehutachiona.
Kushandiswa kwe sodium lactate
Iyo general concentration ndeye 60% -80%, uye iyo yakanyanya kushandiswa muganho we60% yekusungwa ndeye 30g/KG. Inoshandiswa kune zvigadzirwa zvenyama uye huku, ine inhibitory inhibitory effect pamabhakitiriya ezvokudya zvenyama, zvakadai seE. coli, clostridium botulinum, listeria nezvimwe zvakadaro. Kuburikidza nekudzivirirwa kwechikafu pathogenic bacteria, kuitira kuti uwedzere kuchengetedzwa kwechikafu. Wedzera uye uvandudze kunaka kwenyama, kuwedzera hupenyu hwesherufu.
Sodium lactate munyama yakasvibirira ine kupararira kwakanaka, uye ine kunyura kwakanaka kwemvura, kuitira kuti ibudirire kudzivirira kupera simba kwenyama mbishi, kuwana kutsva, kunyorova-kuchengetedza maitiro. Inonyanya kushandiswa kugadzira nyama yakagochwa, ham, soseji, huku uye dhadha zvigadzirwa zvehuku uye sosi uye marinade zvigadzirwa.
