ANSWER

China Patent CN103548985 B (2014) and Su et al. (2003) suggested that 1-methylcyclopropene (1-MCP) treatment can effectively inhibit the release of soybean vegetable (edamame) respiration and ethylene, hence delaying the aging process. 1-MCP treatment combined with MAP packaging showed a decrease in aerobic bacteria count (Oz & Ulukanli, 2011). The addition of calcium during blanching has been found to enhance texture and shelf-life of the vegetables (Xu et al., 2012).
