Abstract:
In this paper, gold nectarine and red peach from Wenshan in Yunnan province were used as research materials, and water treatment was used as control. 1-MCP, ClO2 and 2 coatings were used to treat golden nectarine and red peach and to study the effects of different post-treatment on peach fresh-keeping. The results showed that although the 1-MCP treatment has an effect on the maintenance of L*, a* and b* values of the two peaches, the suitable post-harvest treatment methods for Yunnan golden nectarines and red peaches are different. For the 1-MCP-treated gold nectarine, the difference was the biggest, after 25 days, the L*, a* and b* values were still high, the relative conductivity value was the lowest (54.43%), the mass loss rate was lower (1.05%), and the TSS content was 16.27%, indicating that 1-MCP treatment is more suitable for the storage and preservation of golden nectarine. ClO2 treatment is beneficial to the maintenance of the appearance of red peach. The a* value and b* value after storage for 25 days were higher than other treatments, and had the lowest mass loss rate and the highest TSS content. The relative conductivity value was 55.81%, lower than 1-MCP treatment, indicating that ClO2 treatment is more suitable post-harvest treatment of red peach.
