Improved microbial quality of buckwheat using antimicrobial solutions in a fluidized bed.

摘要: Buckwheat (Fagopyrum esculentum, Moench) is a specialty crop of interest because its numerous nutritional, health, and agronomic benefits. A high microbial load on the seed often limits export use in functional foods; therefore, these generally recognized as safe antimicrobial treatments were evaluated for buckwheat disinfection: ozone gas, ozonated water, acetic acid (AA), acidic calcium sulfate (ACS), combinations thereof. The liquid sprayed grain fluidized bed treated was analyzed aerobic plate count (APC) yeast mold (YMC). Ozone gas water not significantly (P < 0.05) effective reducing load, AA + had significant but low effectiveness. Electron microscopic imaging suggested that rough surfaces crevices hull shielded microbes from treatments. Effectiveness also limited by industry amount moisture can be added to grain. ACS (50 mL/L) treatment most with 3.9-log10 reduction APC complete elimination YMC. caused bleaching increased redness. Sufficient could achieved at lower concentration ACS, thereby effect color.
