Effect of different storage temperature on quality of lotus sprouts

Objective: To study the effect of different temperature on the storage quality of lotus sprouts.Method: A single factor test of lotus sprouts in Hubei area was conducted to measure the browning, water content, relative conductivity, MDA content, PPO activity and firmness by taking lotus sprouts storied at 4, 6, 8, 10℃.Results: As browning degree and cell damage of lotus sprouts was highest at 4℃, it meant low temperature which might cause chilling injury of lotus sprouts was not suitable for lotus sprouts storage.Lotus sprouts had high PPO activity and low firmness when stored at 8℃ and 10℃, but low PPO activity and high firmness at 6℃.Conclusion: 6℃ was optimum for lotus sprouts storage, while neither lower nor higher temperature was good for preserved lotus sprouts.
