Removal of Aflatoxin B ₁ from Peanut Milk Inoculated with <i>Flavobacterium aurantiacum</i>

Abstract

ABSTRACT The ability of F. aurantiacum to reduce the aflatoxin B 1 (AFB 1 ) concentration was determined by inoculating about 10 9 stationary phase cells in AFB 1 ‐contaminated phosphate buffer (PB). non‐defatted peanut milk (NDPM) and partially defatted peanut milk (PDPM). The AFB 1 concentration and cell populations were determined periodically throughout the incubation (30°C). After 24 hr, the concentration of AFB 1 decreased about 40% in PB, 23% in NDPM and 74% in PDPM. Viable cell population decreased less than one log 10 CFU/mL in all liquids but increased about 0.8 log 10 unit in control PDPM. AFB 1 recovery increased about 30% in proteolysed PDPM but proteolysis had no effect on recovery from NDPM.
