Abstract

The technological parameters affecting the recovery yield of Morinda citrifolia L. juice are the concentration of pectinase enzyme, hydrolisis temperature, and hydrolisis time. From that, a process of extraction and recovery of Morinda citrifolia L. juice was developed, with some technological parameters being the concentration of pectinase enzyme used at 0.4%, hydrolisis temperature of 40oC, hydrolisis time of 240 minutes, in this condition, the recovery efficiency yield of Morinda citrifolia L. juice is more than 90%. Besides, it has also been determined that the pressure to recover Morinda citrifolia L. juice is 200kg\cm2, the pressing time is 10 minutes\batch, the centrifugation speed is 8000 rpm and the centrifugation time is 15 minutes. The obtained Morinda citrifolia L. juice is stored in a specialized dark PE plastic bottle with a capacity of 1.5 liters and stored at a temperature of 2 - 4oC. Some biochemical indicators such as total sugar, total protein, vitamin C and color, odor, taste, and clarity parameters of Morinda citrifolia L. juice were determined by analytical methods.
