Abstract: The effects of modified konjac glucomannan ( KGM) coating on fresh- keeping of strawberry had been researched.The results showed that compared with the blank group, the rotting rate and weight loss rate of the strawberry fruits preserved by KGM coating were lower at room temperature. Alkali modified KGM coating treatment gave the best results: the fruits kept the best organoleptic quality during storage, determined 3d after coating, the rotting rate, the weight loss rate and the content decreases of the vitamin C were less than 5%. Determined 7d after coating, the rotting rate was only 24.4%, the weight loss rate was 9.1% and the content decreases of the vitamin C was 11.0%.Modified KGM coating had good preservation effects on strawberry.
