| 为综合评价60Co-γ辐射选育的秀珍菇新菌株福秀5669品种特性与应用前景，按食品安全国家标准的方法测定了秀珍菇子实体中氨基酸、粗蛋白、粗灰分、重金属含量与农药残留量，比较分析了福秀5669与原菌株台秀57子实体中营养成分及重金属与农药残留量的差异性与安全性。研究表明：福秀5669的16种氨基酸、6类氨基酸、粗蛋白、粗灰分的含量高于秀珍菇台秀57，且差异极显著（P<0.01）；福秀5669的重金属铅、砷、镉含量低于台秀57，且差异性显著（P<0.05），两个品种秀珍菇的铅含量均超过国家食品安全标准；福秀5669的汞含量高于台秀57，但低于国家食品安全标准；两个品种秀珍菇农药残留量均符合国家食品安全标准。结果表明，福秀5669的营养品质、重金属与农药残留量安全性均优于原菌株台秀57，具有示范推广前景。 |
| 英文摘要: |
| The aim of this study was to evaluate the characteristics and application prospect of a mutant strain of Pleurotus geesteranus named "Fuxiu 5669". The contents of amino acids, crude protein, crude ash, heavy metals, and pesticide residues in fruiting bodies of Fuxiu 5669 and the original strain "Taixiu 57" were tested according to China Food Safety Standards. Compared with Taixiu 57, Fuxiu 5669 had significantly higher contents of crude protein, crude ash, and 16 amino acids(P<0.01). The contents of lead, arsenic, and cadmium were significantly lower in fruiting bodies of Fuxiu 5669 than in those of Taixiu 57(P<0.01). However, the lead content in fruiting bodies of both Fuxiu 5669 and Taixiu 57 exceeded the level specified in the China Food Safety Standards. The content of mercury in fruiting bodies of either Fuxiu 5669 or Taixiu 57 was lower than the China Food Safety Standards level. Fuxiu 5669 had a higher dose of mercury compared with Taixiu 57. Pesticide residues in fruiting bodies of both Fuxiu 5669 and Taixiu 57 met the requirement of the China Food Safety Standards. These results indicated that the food safety indices of Fuxiu 5669 were superior to Taixiu 57. As a result, Fuxiu 5669 may have better prospect in further applications. |
