Abstract
Blueberry is nutritious but perishable, which could be preserved using edible coatings. However, the blueberry storage kinetics at room conditions were rarely revealed. So, the 'Emerald' blueberries were adopted to divided into four groups including control (CK), carboxymethylcellulose (CMC), chitosan (CS) and layer-by-layer coatings (LBL) groups, to analyze the coatings effects on the blueberry qualities and storage kinetics. The LBL coatings extended the storage life up to 9 days at (20 ± 5) °C and (60 ± 10) % relative humidity. Besides, the zero-order reaction models could be represented the storage kinetics parameters like rotting rate, weight loss rate, hardness, SSC, respiration rate, and DPPH∙ scavenging rate for all coatings, except the cell membrane permeability and the POD activity. The blueberry rotting rate in the LBL group were 0.844/day, showing the slowest variation among the four groups. It provided the optimal edible coatings for blueberry preservation.
