Ubwino wa pawiri dongosolo la zoteteza

Zotetezandizofunika kwambiri zowonjezera chakudya m'makampani azakudya, zomwe zimatha kuletsa kuberekana kwa tizilombo toyambitsa matenda ndikuletsa kuwonongeka kwa chakudya, motero kumapangitsa kuti zinthu ziziyenda bwino.Masiku ano, ogula ambiri ali ndi kusamvetsetsa kwina kwa zosungirako, zosungirako zimatchedwa "mndandanda woipa", kwenikweni, zotetezera ndizochokera kuzinthu zopanda thanzi, kuchuluka kwake kuyenera kutsata mfundo yosagwiritsa ntchito kapena kugwiritsa ntchito zochepa.Choyamba, zotetezera zimakhala zotetezeka mkati mwa malire ogwiritsira ntchito, ndipo zofunikira kwambiri za ogula sizikhudzidwa;chachiwiri, zotetezera zimatha kupangitsa kuti chakudya chikhale chosavuta komanso kuti chikhale chokoma, ndipo kusowa kwa zoteteza kumabweretsa kutaya kwa ogula.Choncho, zotetezera zili pafupi ndi zofunikira za mlanduwu, kufunafuna kothandiza kwambiri, kupyolera mu kuchepetsa kukhathamiritsa, kupatsa mphamvu zakudya ndi njira zina zowonjezera phindu la ntchito.
Ubwino wa compound system of preservatives:
① Wonjezerani mphamvuantibacterialsipekitiramu
②Kupititsa patsogolo mphamvu ya mankhwalawa
③Kuipitsa kwachiwiri
④ Sinthani chitetezo
⑤ Kupewa kuyambika kwa kusamva mankhwala
Njira zophatikizira zotetezera nthawi zambiri zimakhala motere:
① Kuphatikiza zoteteza ndi njira zosiyanasiyana zochitira.Njira yophatikizira iyi siwongowonjezera pang'onopang'ono, koma nthawi zambiri imakhala ubale wochulukitsa, womwe ukhoza kupititsa patsogolo mphamvu ya antiseptic ya zoteteza.
② Kuphatikizika kwa zoteteza ndi mikhalidwe yosiyanasiyana yogwiritsiridwa ntchito.Njira yophatikizira iyi imatha kupereka chitetezo chambiri chambiri pazamankhwala.
③Ndioyenera kuphatikizira zosungiramo tizilombo tosiyanasiyana.Njira yophatikizirayi makamaka ndiyo kukulitsa anti-spectrum ya anti-corrosion system, ndipo ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga zodzikongoletsera za tsiku ndi tsiku.
Ndikoyenera kukumbutsani kuti pophatikizana, chidwi chiyenera kuperekedwa ku kugawanika koyenera kwa zotetezera, ndipo tcheru chiyenera kulipidwa kuti tipewe kuyanjana pakati pa zotetezera, ndipo nthawi yomweyo, tcherani khutu ku antibacterial properties pambuyo pophatikizana.MongaPE91 , PA 73, Phenoxyethanol(CAS No.122-99-6) ndiEthylhexylglycerin (CAS No. 70445-33-9) ndi etc.
