Effect of Thymol/Polylactic Acid Antibacterial Packaging on Storage Life of Blueberry
摘要
Abstract
In order to explore the effect of antimicrobial package with thymol on quality and physiological changes of blueberry,the Bright blueberry were packaged by using thymol/polylactic acid as antimicrobial material,and stored in a low temperature environment.Ordinary PE material was chosen as control.The capability of fresh-keeping based on sense,nutritional quality,fresh rate and antioxidant enzymes activity were investigated to evaluate the preservation effect evaluation of the antimicrobial packaging.As a result,antimicrobial package can significantly decreased the decay incidence of blueberry under O℃ and all the fruits were good even after 36 days,while it can be maintained only for 18 d using PE packaging.The antimicrobial package could maintain higher soluble solid content and fruit firmness,reduce the loss of anthocyanins,total phenolics and Vc.At the same time,it could effectively control the decrease of activities of antioxidant enzymes,such as CAT and SOD,and the increase of PPO activity.However,it was inferior to the traditional PE material in inhibiting fruit weight loss.This study demonstrated that thymol/polylactic acid antibacterial package had good application prospect in postharvest storage of blueberry.In addition,the results provided theoretical basis for the application of this package on fresh-keeping.关键词
