Abstract:

In order to find reasonable and cheap keeping-fresh method for longan (Dimocarpus longan), the optimization of application method using the function bacteria strain Brevibacillus brevis FJAT-0809-GLX to keep the longan fruit (Dimocarpus longan) fresh were compared in this paper. The results showed that the preservation rate was decreased as the concentration dilutions of the fresh-keeping function bacteria strain FJAT-0809-GLX increased, and threshing rate was increased. The highest preservation rate was 75% as the dilution was ten times. The preservation rate of longan fruits with the paper wrapped was higher than that with leaves wrapped, which was 53.28%. The application methods showed that the threshing rate of the fruit for the bacterium spraying before harvest was 24.42%, lower than that spraying after harvest which was 83.33%.
