Kushandiswa kwepropionic acid

1. Inoshandiswa sechinovhara ganda pakuchenesa ganda kuti rirambe richidzivirira alkali uye kuti ganda rirambe rakafanana.

2. Sodium propionate imushonga wekuchengetedza chikafu une acid, uye simba rayo rekudzivirira utachiona rinokanganiswa ne pH yenzvimbo. Kuwanda kwekudzivirira kwakaderera kwaive 0.01% pa pH 5.0 uye 0.5% pa pH 6.5. Ine simba guru rekudzivirira pamhando dzakasiyana dze molds, gram-negative bacilli kana aerobic bacillus mune acidic medium. Ine simba rakakosha pakudzivirira kugadzirwa kwe aflatoxin, asi haishande zvakanyanya pa mbiriso. Muindasitiri yezvekudya, inogona kushandiswa kuchengetedza makeke, uye huwandu hwekushandisa i2.5g/kg (yakaverengerwa se propionic acid, yakafanana pazasi); huwandu hwepamusoro hwekushandisa i50g/kg mu 3% kusvika 5% yemvura inonyudza bayberry. Inogona zvakare kushandiswa semushonga wefungal wekudya.

3, chikafu, chikafu uye mushonga unouraya utachiona, mushonga unodzivirira fungus. Huwandu hwekuwedzera i0.1-0.3%.

4. Zvinochengetedza ganda. Zvine mhando dzakasiyana dzemhedzisiro inorwisa mabhakitiriya pamota, mbiriso uye. Mhedzisiro inorwisa mabhakitiriya inonyanya kuoneka mumushonga weasidhi. Huwandu hunowedzerwa kuzvizoro kazhinji haupfuuri 2%. Mishonga inouraya zvipembenene, fungicides. Kuongororwa kwe transaminases.
