Abstract:

In order to screen out suitable varieties of longan in processing longan dry flesh, 50 longan cultivars and seedling plants were chosen to process longan dry flesh with hot-air drying technology. The factors that affected the quality and processability such as color, taste, smell, particle morphology, processing and yield were analyzed. On the basis of qualitative analysis, the author compared the materials with fuzzy comprehensive evaluation. The results showed that the quality of the same varieties came from different areas did not differ greatly in processing longan dry flesh, and the quality differed greatly among varieties. Of all the varieties in this study, seedling-19 was best in color and shape, seedling-3, Juwu, Guixiang and seedling-23 were best in smell, taste, process and yield, respectively. Of all the varieties, seedling-19, Juwu and seedling-14 were the top three in processing longan dry flesh, respectively. The comprehensive evaluation of them were superior to Shixia, the mainly variety in processing longan dry flesh at present, and they would have high application values in production.
