Zipatso ndi ndiwo zamasamba zimakhalabe zamoyo zitathyoledwa, kupitiriza kupuma ndi kuchita zinthu zamphamvu zamoyo. Kumbali imodzi, kupuma kagayidwe kazakudya kumadya zipatso ndi ndiwo zamasamba zomwe zimapatsa thanzi komanso madzi, zomwe zimakhudza maonekedwe awo ndi khalidwe lawo; Komano, matenda obwera chifukwa cha tizilombo toyambitsa matenda amatha kuyambitsa zipatso ndi ndiwo zamasamba. Chifukwa chake, zipatso ndi ndiwo zamasamba nthawi zambiri zimafota, kutsika bwino, ndikuwola panthawi yosungira, zoyendetsa, ndi zogulitsa, motero kuchepetsa mtengo wa chakudya.
Kupaka bwino sikumangothandiza kusunga zipatso ndi ndiwo zamasamba zatsopano, kuchepetsa kuwonongeka ndi kukulitsa moyo wa alumali, komanso kumakopa ogula ndikulimbikitsa kugwiritsa ntchito mankhwala. Filimu yapulasitiki ndiyomwe imagwiritsidwa ntchito kwambiri popangira zipatso ndi ndiwo zamasamba. Ili ndi zabwino monga kuwonekera, kutsekereza kutentha, kupuma, kusindikiza, ndi mtengo wotsika, ndipo ili ndi chiyembekezo chogwiritsa ntchito msika. Zotsatirazi zikuwonetsa njira zosungira zipatso ndi ndiwo zamasamba.

M'zaka zaposachedwa, izi ma CD zinthu wakhala ankagwiritsa ntchito kunja kwa ma CD zipatso. Kutengera mawonekedwe a thupi la zipatso ndi kulolerana kwawo ndi mpweya ndi mpweya woipa wa carbon dioxide, ma micropores (40μm) amatha kuwonjezeredwa ku thumba la filimu kuti apititse patsogolo kusinthana kwa mpweya, kuchepetsa chinyezi ndi ma metabolites osasunthika mkati mwa thumba, ndikusunga mpweya wa okosijeni mkati mwa thumba pamlingo wapamwamba kwambiri.<1% O2). This prevents excessive oxygen concentration from causing anaerobic respiration, thereby avoiding the accumulation of large amounts of volatile substances such as ethanol and acetaldehyde, which would affect the flavor of the fruit. The oxygen concentration inside the film bag can generally be maintained at around 10-15%, and it is highly tolerant of carbon dioxide concentration, making it especially suitable for fruits and vegetables with high humidity, particularly tropical fruits. In other countries, these packaging bags are used to store "frozen" cherries, which can be preserved for 80 days in ordinary cold storage while maintaining the flavor and quality of the fruit.

Ndi mtundu watsopano wa njira yoyikamo yomwe yatuluka m'zaka zaposachedwa. Mpweya wa okosijeni womwe uli m'matumba ochuluka-oxygen self-oxygen self{2}} nthawi zambiri amasungidwa pa 70-100%. ma CD amenewa ali ndi ubwino zotsatirazi: (1) linalake ndipo tikulephera enzyme ntchito ndi kupewa browning wa zipatso ndi masamba mankhwala; (2) kumalepheretsa kupuma kwa anaerobic ndikusunga zipatso ndi masamba; (3) imalepheretsa bwino kukula kwa aerobic ndi anaerobic kwa tizilombo toyambitsa matenda ndikuletsa zowola, choncho yakopa chidwi kwambiri. Ndizoyenera kwambiri kusungirako zipatso ndi ndiwo zamasamba ndi zipatso ndi ndiwo zamasamba zomwe zimakhala ndi mpweya wabwino wa anaerobic ndi kuwira pansi pa ndende ya carbon dioxide ndi ndende yotsika ya okosijeni. Panthawi imodzimodziyo, kusakanikirana kwa mpweya mkati mwa thumba kumatsimikiziridwa molingana ndi makhalidwe a zipatso ndi ndiwo zamasamba zosiyanasiyana.
