... to show how the amount of juice collected changes over time, with and without the enzyme pectinase. Amount of juice collected (cm3) Rate of collection x 100 (cm3/s) Percentage more apple juice collected with pectinase Time/seconds With pectinase Without pectinase With pectinase Without pectinase 60 4.0 1.2 6.67 2.00 233% 120 5.4 1.4 2.33 0.33 286% 180 6.2 1.6 1.33 0.33 288% 240 6.6 1.8 0.67 0.33 267% 300 6.8 2.0 0.33 0.33 240% 360 7.0 2.1 0.33 0.17 233% 420 7.2 2.2 0.33 0.17 227% 480 7.3 2.3 0.17 0.17 217% 540 7.4 2.4 0.17 0.17 208% 600 7.4 2.4 0.00 0.00 208% I included the column with rate of collection because it will show how much the enzyme improves juice collection. I included the column about the percentage more apple juice collected with pectinase to test the claim that pectinase will increase fruit juice yield by 20%. Analysis of results From my graphs and table I can see that pectinase dramatically increased fruit juice yield. From the table I can see that after just 1 minute, 4cm3 of juice was collected with pectinase and only 1.2cm3 was collected without. From my first graph of amount of juice collected against time, the line for pectinase is much higher that that of without pectinase. The gradient for the graph with pectinase between 0 ...
