1. A na-eji ya eme ihe dị ka ihe na-ekpuchi akpụkpọ ahụ iji melite iguzogide alkali nke akpụkpọ ahụ na otu esi agba akpụkpọ ahụ.

2. Sodium propionate bụkwa ihe nchekwa nri acid, mmetụta ya na-esikwa na bacteriostatic pụta site na uru pH nke gburugburu ebe obibi. Oke mbelata mgbochi kacha nta bụ 0.01% na pH 5.0 na 0.5% na pH 6.5. Ọ nwere mmetụta siri ike na-egbochi ọtụtụ ebu, bacilli gram-negative ma ọ bụ aerobic bacillus na acidic medium. Ọ nwere mmetụta pụrụ iche na izere mmepụta nke aflatoxin, mana ọ fọrọ nke nta ka ọ ghara ịdị irè na yist. N'ụlọ ọrụ nri, enwere ike iji ya maka ichekwa achịcha, ọnụọgụ ojiji ya bụkwa 2.5g/kg (agbakọ dị ka propionic acid, otu ihe ahụ dị n'okpuru); oke ojiji kachasị bụ 50g/kg na mmiri bayberry 3% ruo 5%. Enwere ike iji ya dị ka ihe na-egbochi nje maka nri.
