目前由于在果蔬的储运中常发生霉变、腐烂 ,鲜度下降 ,甚至完全失去商品价值 ,造成巨大的经济损失 ,难以满足市场要求。因此 ,解决果蔬的贮藏特别是运输过程中的保鲜 ,不仅能满足市场需要 ,增加果蔬市场供应品种和调节供应 ,同时还将获得巨大的经济效益。通过正交试验对切分西红柿进行了微波处理常温保鲜的试验研究 ,得出了真空包装的切分西红柿在微波短时处理后只达到巴氏杀菌的低温杀菌温度 ,却得到能长期贮存的品质优良的样品的结果 ;确定了这种方法的最佳处理参数 ,其最佳参数为 0 .12 %维生素 C处理时间为 5 4s;对样品进行图像处理 ,得到色彩直方图和色彩均值 ,用确切的数值说明保鲜方法的保鲜作用 ;分析包装对西红柿保鲜的影响作用 ,认为切分西红柿应采用避光包装保存
At present, mildew, decay and freshness often occur in the storage and transportation of fruits and vegetables, even completely losing the value of commodities, resulting in huge economic losses and difficulties in meeting market requirements. Therefore, the solution to the storage of fruits and vegetables, especially during storage, can not only meet the needs of the market, increase varieties and supply of fruits and vegetables in the market, but also obtain huge economic benefits. The orthogonal experiment was carried out to study the fresh-keeping of microwave-cut tomatoes by slicing tomatoes. The results showed that the vacuum-packed cut tomatoes only reached the pasteurization temperature after microwave short-time treatment, but the long-term storage quality Good sample results; determine the best processing parameters of this method, the best parameter is 0.12% vitamin C processing time is 5 4s; the samples were image processing, the color histogram and the color mean, with the exact Of the value of preservation methods of fresh-keeping effect; analysis of the impact of packaging on the preservation of tomatoes that should be cut tomatoes shielded packaging preservation
