Kusintha kwa malingaliro oletsa ziweto kuti zisagule chakudya cha ziweto mpaka kuphika pamasom'pamaso kwadzetsa njira yatsopano pamsika wazakudya za ziweto.Poyerekeza ndi chakudya chowuma, chakudya chatsopano chimakhala ndi njira zochepa zogwirira ntchito ndipo zimakhala zobiriwira komanso zoyambirira, zomwe zimagwirizana ndi malingaliro omwe akugwiritsidwa ntchito panopa a oweta ziweto pofuna kudyetsa bwino.Ngakhale mbiri yachitukuko ku China siyitali kwambiri, kuthekera kwake pamsika sikunganyalanyazidwe chifukwa zakudya zatsopano za ziweto zimagwirizana ndi momwe amadyera.

Lipoti loyera la 2020 lazakudya pamakampani aku China akuwonetsa, omwe akhudzidwa ndi COVID19, 34.1% ya oweta ziweto amasunga chakudya cha ziweto nthawi ndi nthawi, ndipo 22.7% ya osunga ziweto amangoyang'ana pa alumali moyo wazakudya.Chifukwa chake, kutsitsimuka komanso moyo wa alumali wazakudya za ziweto ndi zinthu ziwiri zofunika kwambiri zomwe zingakhudze zosankha za ogula.Chakudya chaziweto chokhala ndi kutsitsimuka kwambiri chimachita bwino kununkhiza, kukoma, kuvutikira kuyamwa komanso kufunikira kwa zakudya.Kutsitsimuka kwa chakudya chopakidwa kumakhudzana kwambiri ndi kuchuluka kwa oxygen transmittance ratio (OTR) yamapaketi.Filimu yogwira ntchito ya Xiamen Changsu, Supamidseries mankhwala - filimu ya EHA, makulidwe ake ndi 15 μm okha.ndipo OTR yake imayang'aniridwa pansipa 2cc / (㎡. Tsiku. atm), zomwe sizingangotseketsa kutsitsimuka kwa chakudya ndikuchepetsa kwambiri kutayika kwa michere, komanso kutalikitsa moyo wa alumali ndikukwaniritsa malingaliro a osunga ziweto. kusunga chakudya cha ziweto.

Osati zokhazo, pepala loyera la 2020 likuwonetsanso kuti chiwerengero cha oweta ziweto pambuyo pa 80s ndi post-90s ndi 74.3%.Pakati pawo, 84.5% ya post-90s ndi 83.5% ya post-80s amakonda kusankha kugula pa intaneti monga njira yawo yogulira chakudya cha ziweto, zomwe zimatsutsanso mphamvu ya kunyamula chakudya.Kuchuluka kwa mavalidwe a phukusi lakunja kapena kusweka kwa thumba kwa zinthu zogulira pa intaneti pamayendedwe ndizomwe zimakhudza nthawi yowombola ogula.Ndi kusinthasintha kwabwino, kukana kwamphamvu komanso kukana kwapang'onopang'ono, komanso kulimba kwamphamvu komanso kulimba mtima, filimu ya EHA imatha kuteteza zomwe zili mkati mwamayendedwe ndikuwongolera bwino zomwe ogula amagula pa intaneti.

Potengera zomwe oweta ziweto zomwe zili pamwambazi pazakudya ziweto,EHAfilimuyo, yokhala ndi zabwino zake zopangira, yagwirizana ndi mitundu yambiri yazakudya za ziweto kuti agwire ntchito limodzi kuti apereke chakudya chatsopano, chathanzi komanso chopatsa thanzi.
