Description
Summary:This investigation aimed to assess the effects of washing fresh galangal rhizomes on their quality and safety using natural based non-ionic biosurfactant (BSF, 50-200 mg L-1 ) produced from waste sour cherries fermentation. Chlorine-free water and 8 mg L-1 chlorine dioxide were used as control sanitizer treatments. The efficiency of removing S. rolfsii mycelium, dimethoate, and lead (Pb) was tested. The results revealed that 200 mg L-1 BSF reduced the membrane fluidity, and damaged vegetative hypha of S. rolfsii. Due to removing pesticide and heavy metals, 200 mg L-1 BSF was found to be the most effective in controlling dimethoate and Pb levels during storage at 4 C for 7 days, which met the standard of maximum residue level (MRL). It might be concluded that BSF could remove all hazards from contaminated fresh galangals. The washing procedure prototype in this study could be practically used as a sanitation standard operating procedure (SSOP) in food safety management in fresh-cut industry.
