Inactivation efficacy of combination treatment of blue light-emitting diodes (LEDs) and riboflavin to control E. coli O157: H7 and S. Typhimurium in apple juice

출판일자. 202206 Abstract In the present study, we assessed the bactericidal effect of a combination of blue light (BL) and riboflavin (Rb) and elucidated the bacterial inactivation mechanism. Higher Rb concentrations (0.005–50 μM) resulted in greater inactivation of Escherichia coli O157:H7 and Salmonella Typhimurium suspended in phosphate buffer saline (PBS). In the present dose-dependent study, […]

Acrylamide formation in carbohydrate-rich food powders consumed in Korea

출판일자. 202206 Abstract Acrylamide formation in carbohydrate-rich botanical powders consumed in Korea was investigated in this study. Free asparagine and monosaccharide contents were measured as the chief precursors to acrylamide formation. The highest levels of acrylamide were detected in heated lotus roots, followed by potatoes, Jerusalem artichokes, and yams. Tubers and rhizomes contained more asparagine […]
