摘要: 利用离子色谱探究γ射线辐照剂量、VC含量、烟酰胺含量对亚硝酸盐水溶液和卤驴肉中亚硝酸盐降解率的影响,同时利用气相色谱-质谱联用对γ射线辐照后卤驴肉中挥发性化合物成分进行分析。结果表明:γ射线辐照能够有效降解亚硝酸盐水溶液和卤驴肉中的亚硝酸盐,VC对亚硝酸盐水溶液和卤驴肉中的亚硝酸盐辐照降解具有协同作用,烟酰胺对水溶液中的亚硝酸盐辐照降解具有抑制作用,而对卤驴肉中亚硝酸盐辐照降解有协同作用;水溶液中的亚硝酸根离子经辐照后转化为硝酸根离子;卤驴肉经8 、10 kGy辐照后己醛、庚醛含量增加,有异味感。本研究为γ射线辐照降解卤驴肉中的亚硝酸盐提供了技术支持和理论依据。

Abstract: Ion chromatography was used to investigate the effects of γ-ray irradiation dose, vitamin C (VC) content and niacinamide content on nitrite degradation in aqueous solution and spiced donkey meat, and the volatile components of irradiated spiced donkey meat were analyzed by gas chromatography-ion mobility spectrometry. The results showed that γ-ray irradiation could effectively degrade nitrite in both aqueous solution and spiced donkey meat. A synergistic effect was observed when γ-ray irradiation and VC were used together. Nicotinamide had an inhibitory effect on the irradiation degradation of nitrite in aqueous solution, but had a synergistic effect on the irradiation degradation of nitrite in spiced donkey meat. Nitrite ions in aqueous solution were converted to nitrate ions by the irradiation. After 8 or 10 kGy irradiation, the contents of hexanal and heptanal increased, and donkey meat had an off-flavor. This study provides technical support and a theoretical basis for the degradation of nitrite in spiced donkey meat by γ-ray irradiation.

Key words: γ-ray irradiation; nitrite; volatile components; spiced donkey meat
