Abstract

The study was carried out to screen the most suitable method for cowpeas preservation. The cowpeas from Liuzhou were used as the raw materials, and were treated as follows: methyl jasmonate fumigation treatment(MeJA treatment group), ethyl alcohol fumigation treatment(ET treatment group), and 1-methylcyclo-propene fumigation treatment(1-MCP treatment group). The effects of different fresh-keeping treatments on the physiological and nutritional indices in cowpeas during storage(25±1)℃ were determined. Results showed that the MeJA treatment group can significantly decrease the rusty spot index, respiration intensity, soluble pectin content, relative cell membrane permeability and MDA content of cowpeas, effectively sustain the protopectin content compared with the CK group, ET treatment group and 1-MCP treatment group. The weight loss rate, L* value, a* value and cellulose content of MeJA treatment group was not significantly different from that of the 1-MCP treatment group, but were significantly higher than those of CK group and ET treatment group. Therefore, MeJA fumigation treatment shows the optimal effect on maintaining the quality of cowpeas and it has a good application prospect in the preservation of cowpeas.
