Abstract
SummaryFresh American ginseng roots were washed with sanitiser solution (200 ppm sodium hypochlorite), surface‐coated with a coating solution consisting of 0.5% chitosan and three organic acids (lactic, levulinic and acetic acids) and then placed in modified atmosphere packaging (MAP) with 5% O2, 10% O2 or ambient air. Total aerobic bacteria, yeasts and moulds, weight loss and quality changes (texture, colour and appearance) of roots were monitored during storage at 4 °C. Throughout the 38‐week study, there were no significant changes in microbial loads, texture, colour and appearance of samples after sanitiser washing and coating treatments and packaged with air, 5% O2 or 10% O2. The weight loss of roots after 38 weeks was approximately 3%. The results demonstrate that the unique coating formulation (0.5% chitosan and multiple organic acids) and combination of sanitiser washing, coating treatment and MAP extend the shelf life of fresh ginseng roots to at least 38 weeks.
