【摘要】 <正> 柞蚕茧是我国的主要特产之一,仅辽宁省每年产茧100多万担,但在贮藏加工保管上,自缫丝有史以来,基本上采用热蒸气烘杀干燥贮藏。这种方法仅辽宁省每年耗煤万余吨,耗电近60万度。随着原子能事业的飞跃发展和核辐射贮藏保鲜在国内外较广泛的应用,我们改热能烘杀干煤为核辐射活体贮藏保鲜,即用适宜照射量的γ射线照射柞蚕蛹,使其脑神经分更多还原

【Abstract】 The tussah cocoons have been treated by y irradiation to control the pupae development and prolong their preservation period. As compared with the conventional hot steam killing method, it could save energy, cost and improve the quality of silk or cocoons.The experiment showed that the tussah pupae in dormant or pre-blackening period were irradiated by the dosage of 2 × 104R or more, their respiration strength weakened, glycogen consumption decreased and all the metabolisms were inhibited.If the dormant pupae were irradiated by 8-12×104R λ ray, they can be preserved two months longer in ordinary temperature than the controlled. The unraveling technology and silk quality analysis of the tussah cocoons irradiated by 2-25×l04R λ ray keep unchanged as compared with the controlled.更多还原
