Lub tshuab nqus tsev- tsim cov tshuab ntim khoom yog hloov kho thaj chaw faib khoom rau cov khoom lag luam legume. Cov txheej txheem ntim khoom no, uas sib xyaw ua ke ib puag ncig lub tshuab nqus tsev nrog lub tshuab ua kom zoo, suav nrog kev tso cov legumes rau hauv cov hnab ntim cov yeeb yaj kiab, tshem tawm cov huab cua, thiab siv lub zog sab nraud los tsim cov txheej txheem ca. Nws lub hauv paus ntsiab lus tseem ceeb nyob rau hauv ob txoj kev khaws cia: lub tshuab nqus tsev tshem tawm cov pa oxygen inhibits pwm kev loj hlob thiab cov roj oxidation, nrog rau cov ntaub ntawv sim qhia tias nws tuaj yeem txuas lub txee lub neej ntawm legumes los ntawm 3 lub hlis hauv ib txwm ntim rau ntau tshaj 12 lub hlis. Cov txheej txheem tsim, los ntawm kev txhim kho cov khoom zoo, txo cov kev sib txhuam ntawm kev thauj mus los, txo cov taum tawg los ntawm kwv yees li 40% (raws li 2024 kev lag luam qhia los ntawm Tuam Tshoj Ntim Federation).
Daim ntawv thov scenarios qhia cov qauv sib txawv. Cov tuam txhab ua lag luam loj xws li COFCO thiab Wilmar tau ua tiav cov kab ntau lawm, nrog rau ib kab uas muaj peev xwm ua tau 12,000 pob khoom ntawm legumes ib teev. Cov chaw lag luam me thiab nruab nrab- qhov loj me, txwv los ntawm cov nqi khoom siv (tus nqi nruab nrab ntawm ib lub tshuab nqus tsev ib leeg yog kwv yees li 800,000 RMB), feem ntau vam khom rau ib nrab - cov khoom siv tsis siv neeg nrog kev pabcuam phau ntawv. Qhov tseem ceeb, ntau hom legume yuav tsum muaj cov txheej txheem sib txawv: cov noob nplej xws li taum liab thiab taum taum xav tau 0.08MPa lub tshuab nqus tsev kawm ntawv thiab 3- lub sijhawm tuav lub sijhawm thib ob, thaum cov nplej oval zoo li taum taum thiab taum dub yuav tsum tau hloov mus rau 0.06MPa thiab 5-thib ob lub hnab ntim tsis zoo.
Kev lag luam tab tom muaj kev hloov pauv dual uas tau tsav los ntawm kev siv thev naus laus zis thiab kev ua lag luam dynamics. Ntawm ib sab, cov nano tshiab-coated films tau txo cov ntim cov pa xa tawm ntawm 5cc/(m²·24h) mus rau 1.2cc/(m²·24h), ntxiv dag zog rau kev khaws cia. Ntawm qhov tod tes, cov neeg siv khoom nyiam rau "yas- ntim khoom dawb" yog tsav kev tsim kho tshiab, nrog qee lub tuam txhab sim cov ntaub ntawv PLA compostable, txawm tias tus nqi tseem tshuav peb npaug ntau dua li cov yeeb yaj kiab PE. Cov ntaub ntawv ua lag luam qhia tau hais tias qhov nkag mus ntawm lub tshuab nqus tsev- tsim cov khoom lag luam legume hauv Suav teb tau nce mus txog 38% hauv xyoo 2024, suav txog ntau dua 60% ntawm cov khoom lag luam zoo tshaj plaws, thaum kev nce qib tseem qeeb hauv qis -kawg lag luam. Nrog rau kev nce qib ntawm "Food Conservation Action Plan," cov thev naus laus zis no- uas ob qho tib si txo qis kev faib tawm thiab txhim kho kev cia khoom zoo dua - tab tom nkag rau lub sijhawm txhawb nqa txoj cai. Txawm li cas los xij, kev tswj hwm tus nqi ntawm cov khoom siv thiab cov khoom siv hauv cheeb tsam yuav yog qhov tseem ceeb ntawm kev txiav txim siab ntawm nws qhov ceev ceev.
