Introduction Procedure A 5. 00 ml of apple juice was taken in a clean 150 ml conical flask and diluted with 50 ml of distal water. Then, 2. 00 grams of Bakers yeast and 5. 00 ml of solution of Pasteurs salts were added to the above conical flask.The center of flask was shacked well and maintained the temperature of the reaction categorisation between 35-40 ? c by using hot water path. later on that, 10 drops of the reaction mixture from the flask were taken after 10 proceedings and added to a test tube which contained 1. 00 ml of Benedicts reagent. The test tube was placed in hot water for about 2. 00 minutes and changes in color were noticed. The last measuring rod was repeated every 10. 00 minutes for 6 times.The same procedure was used for carrot solution and rate of fermentation for both(prenominal) solutions were found. Observation * Volume of fruit juice taken = 5. 00 ml * Volume of dist. urine added = 50. 0 ml * Weight of Bakers yeast added = 2. 00 gm * Volume of solution of Pasteurs salts = 5. 00 ml Time (Min) Color of reaction mixture on reaction with Benedicts solution in case of Apple Carrot 10 Blue Dark Blue 20 young kelvin 30 Green Green 40 Green Green 50 Green Green 60 Green Dark Blue
