不同辐射剂量对雷竹笋保鲜效果的影响

Effect of Different Radiation Dose on Shoots Fresh-keeping of Phyllostachys praecox

以鲜雷竹笋为试材,研究了1、3、5、7kGy不同辐照剂量对鲜雷竹笋贮藏期间可溶性糖、可溶性蛋白质、维生素C、淀粉及粗纤维含量的影响。结果表明:当辐照剂量为7kGy时对鲜雷竹笋保鲜效果较好,能有效减缓其营养成分的降解,延缓其新陈代谢的进程,有利于其营养成分的保留。

Taking the Phyllostachys praecox shoots as material,the effect of different radiation dose with 1,3,5,7 kGy on the soluble sugar content,soluble protein content,VC content,starch content,crude fiber content were studied.The results showed that the effect was better when the radiation dose was approximate 7 kGy preservation,more condutive to nutrition reservation and slow nutrition ingredient effectively.Advocate for choosing approximate 7 kGy radiation dose to radiation preservation can delay the metabolic process of the fresh Phyllostachys praecox shoots and facilitate its nutrition reservation.
