Kev tuav pov hwmUV{0}}LEDTechnology los tiv thaiv pwm hauv kev txuag zaub mov thiab chav kawm ib puag ncig
Taw qhia
Tom qab-Kev sau qoob loo los ntawm cov kab mob fungal yog ib qho kev sib tw tseem ceeb hauv kev lag luam zaub mov thoob ntiaj teb, ua rau muaj kev poob nyiaj txiag ntau thiab kev txhawj xeeb txog kev nyab xeeb khoom noj. Ntawm cov txiv hmab txiv ntoo uas raug mob feem ntau yog cov txiv qaub ntsuab, uas yog cov perishable heev vim lawv cov qauv ilv thiab siab noo noo. Cov tshuaj fungicides ib txwm siv, thaum ua haujlwm tau zoo, ua rau muaj kev pheej hmoo xws li tshuaj tua kab, kev ua qias tuaj ib puag ncig, thiab kev txhim kho cov kab mob resistant fungal. Hauv kev teb, cov kws tshawb fawb tau hloov mus rau eco-cov thev naus laus zis khaws cia zoo. Ib qho kev cog lus muaj feem cuam tshuam nrog kev siv lub teeb ci ultraviolet (UV) ua ke nrog lub teeb -emitting diodes (LED) los qhib cov tshuaj tiv thaiv kab mob. Tsab ntawv xov xwm no tshawb txog qhov kev ua tiav tsis ntev los no hauv daim teb no thiab txuas ntxiv nws daim ntawv thov rau hauv chav kawm ib puag ncig, qhov kev tswj xyuas qhov chaw huv yog qhov tseem ceeb sib npaug.
Kev cais tawm thiab kev txheeb xyuas ntawm Spoilage Fungi hauv Green Lemons
Ib txoj kev tshawb fawb 2025 luam tawm hauvFood Sciencecais thiab txheeb xyuas cov kab mob fungal thawj lub luag haujlwm rau kev tshaj tawm -cov qoob loo ntawm cov txiv qaub ntsuab hauv Chongqing, Suav. Los ntawm kev soj ntsuam morphological thiab molecular biology cov txheej txheem (ITS cheeb tsam sequencing), peb lub ntsiab spoilage fungi tau txheeb xyuas:
F1: Penicillium digitatum
F2: Penicillium jacksonii
F3: Penicillium italicum
Kev kuaj kab mob tau lees paub tias tag nrho peb hom kab mob tuaj yeem ua rau muaj kev noj qab haus huv ntawm cov txiv qaub ntsuab, nrog F1 thiab F3 qhia tshwj xeeb tshaj yog muaj zog spoilage [1]. Cov fungi no paub tias yuav ua rau softening sai, discoloration, thiab kev loj hlob ntawm unpleasant tsw, ua rau cov txiv hmab txiv ntoo unsellable thiab tsis zoo rau noj.
Novel Antifungal Solution: UV-LED-Induced Composite Txheej
Pab neeg tshawb fawb tau tsim kho tshiab tshuaj tiv thaiv kab mob: ib qho chitosan (CTS)-TiO₂-Ag cov txheej txheem txheej txheej tau qhib los ntawm UV teeb ua ke nrog ntau yamLED wavelengths muaj. Nov yog vim li cas qhov kev sib xyaw no muaj txiaj ntsig zoo:
Chitosan (CTS):Natural biopolymer nrog cov khoom siv tshuaj tua kab mob.
TiO₂ (Titanium Dioxide):Lub photocatalyst uas, thaum raug lub teeb, generates Reactive Oxygen Species (ROS) uas puas hlwb microbial.
Ag (Silver Nanoparticles):Nkag mus rau phab ntsa ntawm tes thiab cuam tshuam kev ua haujlwm ntawm tes.
UV-LED Activation:UV lub teeb (365 nm) pretreatment, ua raws li qhov tshwj xeeb LED wavelengths, txhim khu kev ua haujlwm photocatalytic ntawm TiO₂ thiab Ag, tsim kom muaj kev sib koom ua ke muaj zog tiv thaiv kab mob.
Cov ntaub ntawv-Tom qab siv tau tawm tsam Lemon Spoilage Fungi
Txoj kev tshawb fawb no tau txheeb xyuas qhov cuam tshuam inhibition siv ntau yam kev ntsuas. Cov kev tshawb pom tseem ceeb tau sau tseg hauv qab no:
1. Inhibition Zone Txoj kab uas hla
Cov txheej txheem sib xyaw, thaum ua haujlwm los ntawm UV ua ke nrog LED teeb liab rau 90 feeb, tsim qhov loj tshaj plaws inhibition zones rauP. digitatum(F1) thiabP. italicum(F3), nrog txoj kab uas hla ntawm 8.38 hli thiab 10.49 hli, feem. RauP. jacksonii ib(F2), UV-LED lub teeb ntsuab rau 60 feeb tau zoo tshaj plaws, ua rau thaj tsam 9.69 mm. Cov txiaj ntsig no tau loj dua li cov pab pawg tswj hwm, ua kom pom muaj zog tiv thaiv kab mob [1].
2. Mycelial Growth Inhibition
Kev kho mob hnyav txwv kev loj hlob ntawm fungal. Tom qab 90 feeb ntawmUV-LED teeb liabraug, mycelial kev loj hlob inhibition tus nqi rau F1, F2, thiab F3 mus txog 90.57%, 60.21%, thiab 56.06%, feem. Qhov hnyav qhuav ntawm cov kab mob fungal mycelia kuj txo qis, lees paub qhov kev tawm tsam ntawm fungal proliferation [1].
3. Cell Membrane puas
Kev kho mob cuam tshuam qhov kev ncaj ncees ntawm cov kab mob fungal ntawm tes, qhov tseem ceeb rau kev ciaj sia ntawm tes. Cov cim tseem ceeb ntawm qhov kev puas tsuaj no pom tias muaj kev nce ntxiv:
Extracellular conductivity:Nce, qhia ion to los ntawm cov hlwb puas.
Protein thiab Nucleic Acid Leakage:Ntsuas los ntawm OD₂₈₀ thiab OD₂₆₀ cov txiaj ntsig, cov kev ntsuas no tau nce siab, qhia tias cov khoom tseem ceeb ntawm tes tau tawm mus, ua rau kev tuag ntawm tes [1].
Lub ntsiab lus xaus yog qhov ntawdUV ua ke nrog LED teeb liab rau 90 feeb muab qhov ua tau zoo tshaj plaws thiab zoo ib yam inhibition thoob plaws peb hom kab mob fungal [1].
Los ntawm Lemon Grove mus rau Chav Kawm: Daim Ntawv Thov Kev Pom Zoo
Cov hauv paus ntsiab lus tau pom nyob rau hauv txoj kev tshawb fawb txog kev khaws cia zaub mov no muaj kev siv ncaj qha thiab tseem ceeb hauv lwm cov haujlwm, tshwj xeeb hauv cov chaw kawm. Cov chav kawm yog siab - ib puag ncig kev tsheb khiav uas cov rooj zaum, rooj zaum, cov khoom ua si, thiab lwm qhov chaw tuaj yeem muaj pwm, kab mob, thiab kab mob. Cov kab mob no ua rau muaj kev kis tus kab mob, ua rau cov tub ntxhais kawm thiab cov kws qhia ntawv tsis tuaj kawm ntawv.
Kev tuav ib puag ncig kev huv hauv chav kawm yog qhov tseem ceeb rau cov tub ntxhais kawm kev noj qab haus huv thiab kev kawm tau zoo. Qhov muaj peev xwm ua pov thawj ntawm UV-LED- cov tshuaj tua kab mob los cuam tshuam thiab rhuav tshem cov kab mob fungal qhia tau tias yog lub cuab yeej muaj zog rau kev tua kab mob saum npoo. Los ntawm kev siv cov thev naus laus zis no, cov tsev kawm ntawv tuaj yeem tsim qhov chaw kawm muaj kev nyab xeeb thiab noj qab nyob zoo.
Kev pom zoo: Shenzhen Benwei Teeb pom kev zoo UV Dej nyab lub teeb
Txhawm rau siv cov thev naus laus zis no kom zoo rau hauv qhov chaw loj, sib koom xws li chav kawm thiab chav tsev kawm ntawv, yuav tsum muaj kev xa khoom zoo thiab muaj txiaj ntsig.Shenzhen Benwei Teeb pom kev zoo, tus thawj coj hauv kev daws teeb pom kev zoo siab, muab cov khoom tsim nyog rau txoj haujlwm no:Benwei UV Dej nyab lub teeb.
