Preservation Effect of Thymol Active MAP Packaging on Fresh-Cut Lotus Root

摘要

In order to extend the preservation period of fresh-cut lotus, three kinds of packaging films were applied to investigate the modified atmosphere effect on fresh-cut lotus. In the experiments, LDPE packaging was used as control while laboratory, self-made SBS/LDPE packaging with and without thymol natural extract active MAP packaging were comparatively studied. The quality properties of samples were measured during 8 days at 4 ± 1 °C and 60 ± 2 % relative humidity. The gas concentration in the package atmosphere and the physiological parameters including browning index, weight loss, hardness, and appearance were measured periodically. The experimental results show that thymol active packaging can slow down the fresh-cut lotus respiration and thus extend the preservation period of fresh vegetables.
