Hauv txoj kev tshawb fawb no, biodegradable cov yeeb yaj kiab tau tsim los ntawm Chitosan (Ch) enricsed nrog ntau yam ntxiv nrog rau cov roj to Chloride (CACL2) thiab kom pom cov npe pos-sau kale zoo thaum tub yees. Cov txiaj ntsig qhia tau hais tias muaj kev sib txuam ntawm ZNO / PG / CACL2 rau hauv ib qho kev sib kis dej, nce tensile lub zog, thiab yog dej soluble thiab biodegradable hauv xwm. In addition, CH-TEO-based films combined with ZnO/PEG/NC/CaCl2 were significantly effective in reducing physiological weight loss, maintaining total soluble solids, titratable acidity, and maintaining chlorophyll content, and showed lower a*, inhibiting microbial growth. , tsos thiab pretoleptic zoo ntawm cov zaub qhwv tau khaws cia rau 24 hnub piv rau LDPE thiab lwm cov yeeb yaj kiab biodegradable. Peb cov txiaj ntsig qhia tau tias ch-based zaj duab xis enriched nrog teo thiab ntxiv rau kev ua kom muaj zog, thiab ib puag ncig zoo rau kev khaws cia lub neej ntawm cov tub yees thaum ua tub yees thaum tub yees
Cov khoom siv hluavtaws polymeric ntim tau los ntawm roj av tau ntev tau siv nyob rau hauv kev lag luam khoom noj kom ntseeg tau cov khoom noj muaj ntau yam khoom noj. Qhov zoo ntawm cov ntaub ntawv ib txwm muaj tshwm sim vim qhov yooj yim ntawm kev tsim khoom, nqi qis thiab cov teeb meem loj thiab cov teeb meem loj thiab cov teeb meem zoo tshaj plaws. Txawm li cas los xij, kev siv loj heev thiab pov tseg ntawm cov khoom tsis muaj kev txwv tsis muaj kuab paug yuav inevitably exacerbate ib puag ncig kev muaj kuab paug paug. Hauv qhov no, kev txhim kho kev tiv thaiv ib puag ncig cov ntaub ntawv ntim khoom tau ceev ceev hauv xyoo tsis ntev los no. Cov yeeb yaj kiab tshiab no tsis muaj tshuaj lom, biodegradable, nyob ruaj khov thiab biocompice1. Ntxiv rau qhov tsis muaj tshuaj lom thiab biocompibic, cov yeeb yaj kiab no raws li cov tshuaj tua kab mob ntuj thiab yog li ntawd ua kom muaj kev sib txuas ntawm cov tshuaj ntxiv xws li phahalates. Yog li ntawd, cov saim no tuaj yeem siv los ua lwm txoj kev xaiv uas tsim nyog rau cov roj av ib txwm muaj rau cov khoom siv roj av ib txwm muaj nyob rau hauv cov khoom ntim khoom noj khoom haus. Niaj hnub no, biopolymers tau muab los ntawm cov protein, lipids thiab polysaccharides tau tsim tau zoo, uas yog ib cov ntaub ntawv ntim khoom ntiag tug tshiab. Chitosan (Ch) yog siv dav hauv cov khoom noj ntim khoom noj, suav nrog cov yeeb yaj kiab thiab cov duab hmoov zoo, thiab cov kws kho mob zoo, thiab cov kws kho tshuab , 5. Txawm li cas los xij, cov tshuaj tiv thaiv kab mob antioxidant thiab cov tshuaj tua kab mob uas yog cov qauv tseem ceeb rau cov hom zaub mov ntim cov khoom noj uas tsim nyog.
Cov roj tseem ceeb tau muab los ntawm cov nroj tsuag tuaj yeem cuam tshuam rau hauv cov yeeb yaj kiab biopolymer lossis cov tshuaj tua kab mob rau kev siv lub neej ntawm cov khoom noj. Thyme tseem ceeb heev yog kawm txog kev kawm thiab siv cov roj tseem ceeb vim nws cov tshuaj tua kab mob thiab tshuaj tiv thaiv kab mob. Raws li cov muaj pes tsawg leeg ntawm cov roj tseem ceeb, ntau yam paj lug thyme tau pom, suav nrog thymol (1-44%), lus cov nyiaj (3-4%). %) thiab carvacrol (2-8%) 9, txawm li cas los xij, thymol muaj cov nyhuv muaj zog tshaj vim yog cov ntsiab lus ntawm phenols hauv IT10. Hmoov tsis zoo, kev suav nrog cov nroj tsuag tseem ceeb lossis lawv cov khoom xyaw nquag hauv biopolymer matrices muaj zog txo cov maonocomposite firms11,12. Qhov no txhais tau tias ntim cov ntaub ntawv thiab cov yeeb yaj kiab yas muaj cov roj tseem ceeb rau kev txhim kho cov khoom siv tshuab ntawm lawv cov khoom noj ntim khoom noj.
