Screening,identification and application of superior lactic acid bacterium in Enshi pickle
摘要
Abstract
To improve the flavor and quality of Enshi pickle,the superior lactic acid bacterium with strong acid-producing capacity was screened from local Enshi radish pickle and pickling water,and morphological observations and molecular biological identification were conducted.The screened strains were applied in pickle fermentation,and their fermentation performance was investigated.The results showed that a total of 4 superior lactic acid bacterial strains were screened,numbered MP4,MP30,MS12 and MS 15,respectively.All of them had strong antioxidant activity and could tol-erate 2.0 mmol/L H2O2,0.8%bile salts and a relatively low pH(2.5).The strain MP4 was identified as Lacticaseibacillus paracasei,the strain MP30 as Lactiplantibacillus plantarum,the strain MS12 and MS15 as Pediococcus acidilactici.The quality of pickle fermented by the four selected strains was better than that of natural fermentation.The total acid content of pickle fermented by strain MS 15 was 5.74 g/kg,the elasticity was 0.53,and the sensory score was 89.92,showing the potential of single-strain fermentation of pickle.A total of 37 volatile flavor components were detected in the fermented pickles of the four experimental groups and the control group,including 9 alcohols,6 aldehydes,12 esters,2 alkenes,3 ketones,4 acids and 1 amine.The contents of volatile flavor components in the pickle of the experimental groups ranged from 2.45 to 2.83 g/L,which were much higher than the naturally fermented radish pickle(1.84 g/L).关键词
