摘  要:
选用壳聚糖作为涂膜剂处理带壳小竹笋,在4℃低温,相对湿度94%条件下贮藏保鲜25d。贮藏期间对竹笋的失重率、纤维素和VC含量以及氨基酸总量进行了测定。试验结果表明:1.5%壳聚糖混入1.0%对羟基苯甲酸乙酯制成的涂膜剂有较好的保鲜效果,抑制失重和纤维素含量增加有明显效果。用同法处理的带壳乌笋保鲜效果比雷笋好。

摘  要:
Shelly bamboo shoots were soaked in a solution of chitosan to form a coating on their surfaces. The treated shelly bamboo shoot were stored at 4℃ and 96% RH for 25 days.Weight loss,cellulose,VC and total amino acid were measured during storage.Effect of concentrations of coating agents on shelly bamboo shoot quality was studied and compared.A solution consisting of 1.5% chitosan mixed with 1.0% pethylhy droxy benzoate had a better effect on storing shelly bamboo shoot.
