| 摘 要： | 通过微波辅助化学还原法制备纳米银,对圣女果进行涂膜处理,以研究纳米银溶液对圣女果保鲜效果的影响。结果表明:纳米银溶液对圣女果有较好的保鲜效果。经纳米银涂膜处理的圣女果,贮藏15 d后硬度提高了40%,可溶性固形物和Vc含量下降幅度均低于对照组近一倍,经感官评定,涂抹处理能有效降低圣女果的腐烂率,延长贮藏期,并保持其营养品质。

| Abstract: | The microwave-assisted chemical reduction method was used for the nano-silver to yield a coating.The coating was used to treat cherry tomato.The treated cherry tomato during storage was periodically measured in order to investigate its fresh-keeping effect.The results showed that nano-silver exhibited the best fresh-keeping effect on cherry tomato.Compared to uncoated ones,its hardness was enhanced by 40%,the contents of soluble solids and Vc were lower than uncoated ones nearly doubled after 15 days of storage.Through the sensory evaluation,the nano-silver treatment could significantly reduce the rotting rate of cherry tomato,prolong its shelf-life and maintain the sensory quality of cherry tomato during storage. |
