The interactive effect of fungicide residues and yeast assimilable nitrogen on fermentation kinetics and hydrogen sulfide production during cider fermentation

Abstract

Cidermakers should be aware that residual fenbuconazole (as low as 0.2 mg L^-1 ) in apple juice may lead to stuck fermentation, especially when the YAN concentration is below 250 mg L^-1 . These results indicate that fermentation problems attributed to low YAN may be caused or exacerbated by additional factors such as fungicide residues, which have a greater impact on fermentation performance under low YAN conditions. © 2016 The Authors.
