摘要
Abstract
Edible cling film is widely used in fruit and vegetable preservation and has important commercial value.This study detailed the development of an edible film using gelatin and glycerol as a matrix to immobilize Lactiplantibacillus plantarum SCSL-1 for food preser-vation.The initial step involved quantifying the viable bacterial count in the prepared film.Subsequently,the mechanical properties,mois-ture content,swelling rate,water solubility,water vapor permeability,and light transmittance of the film were optimized.Structural analy-sis of the edible film was performed using Fourier transform infrared spectroscopy and scanning electron microscopy.Finally,the efficacy of the film was evaluated through its application in preserving mangoes.The application in mango preservation was also evaluated.The results showed that the viable bacterial count remained above 107 CFU/g in the gelatin film containing 1.4 g glycerol after storage at 5℃ for 14 days.The L.plantarum SCSL-1 edible film was able to effectively slow down the rotting and deterioration of mango,to maintain its freshness and to significantly reduce the bacterial growth rate in mango preservation and storage.In conclusion,the L.plantarum SCSL-1 edible cling film shows great potential for the packaging and preservation of perishable fruits and vegetables.关键词
