Abstract:The effects of three preservation methods (ultrasound, ZnO NPs, and ultrasound combined with ZnO NPs) on the odor, microstructure, and edible quality of fresh-cut lettuce were investigated in this study. When stored for 8 days, significant improvements were observed in the following when using ultrasound combined with ZnO NP treatment to better preserve fresh-cut lettuce (and were reduced when compared with the control group): the color (L* value (34.53); a* value (−5.89); b* value (15.00); browning index (40.… Show more
