5. Matambudziko Anogona Nekutambanudza Firimu Yekudya
Nepo kutambanudza firimu kuri nyore, kune mashomadownsideskuishandisa kuchengetedza chikafu:
Kufema Kunokwana: Sezvambotaurwa, nepo firimu rakatambanudzwa rinogona kubatsira kuchengetedza chikafu kwenguva yakati, hachibvumiri kutenderera kwemhepo. Izvi zvinogona kunetsa kune zvimwe zvekudya, senge zvibereko zvitsva, zvinoda kufefetera kwemhepo kugara kutsva kwenguva yakareba.
Durability: Firimu rekutambanudza rinowanzo kutetepa kupfuura mamwe maputi echikafu, zvinoreva kuti rinogona kusapa dziviriro yezvekudya zvakapfava. Kana ikasabatwa zvakanaka, inogona kubvaruka kana kutsemuka, zvichiita kuti chikafu chive neutachiona.
Haina Yakanakira Kutonhora: Nepo firimu rakatambanudzwa rinogona kushandiswa kuomesa chikafu, haripe mwero wakafanana wekudzivirira kubvafiriza kupisasemabhegi efiriza akasarudzika kana vacuum-seal packaging.
Dzimwe nzira dzekutambanudza Firimu reChikafu Packaging
Kana iwe uchinetseka pamusoro pezvipimo zveakatambanudzwa firimu rekuchengetedza chikafu, funga dzinotevera dzimwe nzira:
Batisisa Putira: Kusiyana nefirimu yakatambanudzwa, kunamatira kuputira (inozivikanwawo sekuputira kwepurasitiki) yakagadzirirwa kudya. Ine aclingy natureiyo inonamatira kune nzvimbo dzekudya, ichigadzira chisimbiso chakasimba kuchengetedza chikafu chitsva. Inowanikwa mune zvese zviri zvivirifood-gradeuyecommercialmamakisi.
Vacuum Sealer Mabhegi: Nekuchengetedza kwenguva refu, kuvhara kwevacuum ndiyo imwe yenzira dzakanakisisa dzekuchengetedza chikafu nekubvisa mweya uye unyoro. Vacuum sealer mabhegi akagadzirirwa kudzivirira kupisa kwefiriza uye kuwedzera hupenyu hwesherufu yechikafu.
Foil uye Parchment Pepa: Kune mamwe marudzi echikafu, kunyanya ayo aunoda kubika kana kuchengeta mufiriji,foilkanabepa rematehweinogona kupa dziviriro iri nani kubva pakurasikirwa kwemwando uye kusvibiswa.
Glass Containers kana BPA-Yemahara Plastic Containers: Nekuchengetedza chikafu kwenguva yakareba, kushandisa girazi risina mhepo kana midziyo yepurasitiki isarudzo yakavimbika pane yekuputira epurasitiki. Midziyo iyi inogona kushandiswa zvakare, zvichiita kuti ive nehushamwari hwezvakatipoteredza.
Mhedziso: Shandisa Stretch Firimu neYambiro yeChikafu
Mukupedzisa,kutambanudza firimuinogona kushandiswa kuchengetedza chikafu, asi haisi nguva dzose yakanakisa sarudzo zvichienderana nechikafu chaicho uye yaunoda kuchengetedza nguva. Kana yakashandiswa zvakanaka uye mumamiriro ezvinhu akachengeteka ezvokudya, kutambanudza firimu kunogona kubatsira kuwedzera hupenyu hwemasherufu ezvimwe zvinhu, kunyanya mukuchengetedza kwenguva pfupi. Zvisinei, kuitira kuchengetedza kwenguva refu kana zvimwe zvinhu zvakapfava, kune dzimwe nzira dzekurongedza dziri nani dziripo.
Kune yakachengeteka uye inoshanda zvakanyanya kurongedza chikafu, gara uine chokwadi chekuti zvinhu zvaunoshandisa ndezvefood-gradeuye inosangana nezvinodiwa zvekuchengetedza.
Kana iwe uchida kudzidza zvakawanda nezve yakatambanudza firimu uye mashandisiro ayo muzvikamu zvakasiyana, inzwa wakasununguka kushanyira webhusaiti yeduhere. Isu tinopa zvakasiyana-siyana zvekurongedza zvinhu zvakagadzirirwa zvakasiyana siyana zvinodiwa.
