Initial Studies on Improving Quality of Mustard Tube Pickle

The multiplication of Bifidobacterium Longum in artificial inoculate pickles fermented by Lactobacillus plantarum was mainly studied in the paper.A few of growth factors were compared.The medium fermented solution formula and the best conditions were determined.The Bifidobacterium Longum number of pickle in different packages were compared finally.The results showed that: three different extraction liquid of jerusalem artichoke,potatoes,soybean had proliferation fuction to Bifidobacterium Longumr and jerusalem artichoke was the best.20% tomato juice and 2% extractions from Jerusalem artichoke in skim milk could accelerate to produce acid and attain higher Bifidobacterium Longum number.The best formula of fermenting liquid was 1.0% salt,20% tomato juice,1.0% glucose,2.0% soybean milk and 2% Jerusalem artichoke extraction.The best mixed fermentation conditions were bacteria ratio of 2:1,pH6.8 inoculum concentration of 6% at 36 ℃.Pickle had a good taste with ratio of mixed at 1:2 of Bifidobacterium Longum and lactobacillus,cultured for 18~24h and 16h individually.The vacuum-packed could be good to keep higher Bifidobacterium Longum number.
