Abstract: The fresh fruit of ‘Ningqi Ⅶ’ wolfberry was used as test material, and dewaxed with different pH micro electric water, different concentrations of edible lye and different soaking time.The effects of different treatments on the dehydration rate of fresh wolfberry fruit, total sugar content, polysaccharide content, betaine content, commodity rate, color, phase and drying cost were studied, in order to obtain more efficient, environmentally friendly medlar dry dewaxing agent and its application method.The results showed that micro electric water and edible lye dewaxing agents and their treatment levels had significant effects on the dehydration rate, commodity rate, appearance phase and drying cost of ‘Ningqi Ⅶ’ fresh fruit, but had no significant effect on the contents of total sugar, polysaccharide and betaine.Among them, the micro electric water treatment had no alkali powder residue on the fruit surface, reduce drying cost by 29.11%,but the commodity rate was 10.55%,and the dehydration rate was slow.The residue of alkali powder on the fruit surface treated with edible lye was obvious, the cost was high, the appearance and taste were poor, but the commodity rate was high and the dehydration speed was fast.In production, the pH of micro electric water 10.5 and the soaking time 2 minutes were better.
