摘要
Abstract
The excellent biodegradability and low toxicity of chitosan(CS)make it a promising candidate for the development of innovative food packaging films.To address the limitations of CS,including its weak mechanical properties,narrow antibacterial spectrum,and limited air permeability by incorporating chestnut bract extract(CBE)into CS,the CBE-CS composite films were prepared using the solution casting method.The effects of the CBE addition amount on the structure,physical properties,antioxidant activity,and antibacterial activity of the films were investigated,followed by an assessment of the preservation effect of the CBE-CS composite films on strawberries.The results reflected that compared with CS film,the addition of CBE significantly enhanced the mechanical properties,antibacterial efficacy,and antioxidant capacity of the films.Particularly,the addition of 1.28％CBE resulted in a remarkable increase in antioxidant capacity from 5.07％(in pure CS film)to 67.94％.In the fresh preservation experiment of strawberries,compared with CS film,the CBE-CS composite film significantly reduced spoilage and weight loss.When the addition of CBE was 1.28％,the weight loss rate decreased from 54.22％(pure CS film)to 36.02％.This study could provide novel insights and theoretical supports for utilizing chestnut bract waste in food packaging films.关键词
