"I-National Food Safety Standard for Canned Food GB7098-2015" ichaza ukudla okusemathinini kanje: Ukusebenzisa izithelo, imifino, isikhunta esidliwayo, imfuyo kanye nenyama yenkukhu, izilwane zasemanzini, njll. njengezinto zokusetshenziswa, ezicutshungulwa ngokucutshungulwa, ukucwiliswa, ukuvala, ukuvala inzalo yokushisa. kanye nezinye izinqubo zokuhweba ukudla okusemathinini okuyinyumba. "Kungakhathaliseki ukuthi inyama ekheniwe ku-tinplate noma isithelo esifakwe ethini emabhodleleni engilazi, nakuba inqubo yokukhiqiza ihluke kancane, umongo uwukuvalwa inzalo." Ngokwezindinganiso kazwelonke zamanje zaseShayina, ukudla okusemathinini kudinga ukuhlangabezana "nobunyumba bezentengiselwano". Ngokolwazi, indlela yokuqala yokuvala inzalo yabiliswa (amadigri angu-100), kamuva yashintshwa yaba isixazululo se-calcium chloride esibilayo (amadigri angu-115), futhi kamuva yathuthukiswa yaba ukuvala inzalo komfutho ophezulu (amadigri angu-121). Ngaphambi kokuphuma efekthri, ukudla okusemathinini kufanele kube ngaphansi kokuhlolwa kobunyumba kwezohwebo. Ngokulingisa isitoreji segumbi lokushisa, kungabonakala ukuthi ukudla okusemathinini kuzoba nokuwohloka njengokuvuvukala nokuqhuma. Ngokuhlola isiko le-microbial, kuyenzeka ukubona ukuthi akhona yini amathuba okuzala amagciwane. “'Ubunyumba bezentengiselwano' akusho ukuthi awekho nhlobo amagciwane, kodwa ukuthi alinawo ama-pathogenic microorganisms." UZheng Kai uthe amanye amathini angase aqukathe inani elincane lama-non-pathogenic microorganisms, kodwa ngeke akhiqize emazingeni okushisa avamile. Isibonelo, kungase kube nenani elincane lezinhlamvu zesikhunta ku-tomato unamathisele ethinini. Ngenxa ye-acidity eqinile ye-tomato paste, lezi zinhlamvu akulula ukuzala, ngakho izinto ezilondolozayo zingashiywa.”
