微孔气调包装参数优化及其对甜龙竹笋贮藏特性与微生物群落的影响
Optimization of Microporous Modified Atmosphere Packaging Parameters and Their Effects on Storage Characteristics and Microbial Community in Dendrocalamus brandisii Shoots
摘要
Abstract
To explore the effects of modified atmosphere packaging(MAP)with a microperforated film under optimal pore parameters on the quality characteristics and microbial community in postharvest Dendrocalamus brandisii shoots during storage,the Del-Valle equation was used to determine the optimal micropore parameters.A non-perforated film was used as the control to observe the changes in appearance,physiochemical properties,and microbial community in D.brandisii shoots during storage at room temperature.The results showed that MAP with a laser microporous film(LMF)with 3 pores(shell group)and 2 pores(peeled group),at a pore size of 200 μm in diameter,effectively delayed the decrease in L* value,maintained relatively high hardness of D.brandisii shoots,reduced the respiration rate and mass loss rate,and slowed down the increase in relative electrical conductivity and malondialdehyde(MDA)content.The LMF treatment effectively inhibited the proliferation of bacteria,molds,and yeasts in D.brandisii shoots.The results of microbial sequencing indicated that the LMF treatment regulated the bacterial community diversity in D.brandisii shoots,and its inhibitory effect on the fungal community was more pronounced.It inhibited the growth of the bacterial genera Leuconostoc,Lactococcus,and Klebsiella.Furthermore,it suppressed the proliferation of fungal phyla such as Basidiomycota and blocked the growth of the genus Preussia.This study provides a theoretical foundation for the application of microporous modified atmosphere packaging technology in the preservation and processing of D.brandisii shoots.关键词
