Study On The Fermentation Drink Of Condonpsis Lanceolata Juice By Lactobacillus

Codonopsis lanceolata also calls grow wild carrot. It is Campanulaceae perennial liane. It has fatroot and tender fruit that is edible. It mainly contains the flavonoid, and also contains Volatile oil, starch,flavonol glucoside, vitamin, amino acid, Mineral substance and so on that be appraised by "The ChineseMinistry of Agriculture special economical zoology and botany and the product quality surveillanceexamine the test center". It is important health foods raw material.The experiment take codonopsis lanceolata as a raw material, mainly research the domestication oflactic acid strain, the condition of fermentation,compounding, the product's stability etc. of thecodonopsis lanceolata lactic fermentation beverage. The experiment has mainly obtained the followingresult:1. The condition of decortication: oven dry codonopsis lanceolate 20 minutes in the condition of 100centi-degree, decortication method is half artificial half machinery.2. Gradually enhances the raise centralism Codonopsis lanceolata juice density, domesticate St and Lb,at last, selecting the proportion of 5:5 to prepare leaven. After domesticating the St and Lb, the time ofmilk curd short 1.5hours and 2 hours. The Acidity enhance 100% and 106%. The viable count enhance8.6 times and 10 times.3. The best Craft condition of the codonopsis lanceolata lactic fermentation beverage: St:Lb=1:1, thetemperature of fermentation is 42 centi-degree, the amount of inoculation is 5%, the time offermentation is 8 hours.4. The best compounding of the codonopsis lanceolata lactic fermentation beverage: the concentrationof fermentation juice is 75%, the amount of sucrose is 8%, the amount of citric acid is90°T.5. The best compounding of stabilizer about the codonopsis lanceolata lactic fermentation beverage:PGA is 0.1%, sodium polymannuronate is 0.1%, xanthan gum is 0.2%.6. The best homogenization conditions of the codonopsis lanceolata lactic fermentation beverage: thetemperature is 60 centi-degree, the pressure is 20MPa, the number of times is 2.7. The best sterilization conditions of the codonopsis lanceolata lactic fermentation beverage:95centi-degree, 5 minutes.
