Study of the volume and life of the juice in clemenules

Full study

The purpose of this study is to determine, for each type of treatment, the volume obtained from a specific amount of clemenul orange and the life of these by studying the amount of galacturonase present.

By comparing the starting weight and the amount of juice obtained, we can obtain the percentage of juice with respect to 1e total fruit. This comparison between the different samples shows that sample C (of 2,52 kg 0,55 L is obtained) 22,78 % of the fruit is juice, much higher than
obtained in samples A (18,2 %) and sample B (16,31 %), the latter being the least juice obtained from the same weight.

In terms of total nitrogen concentrations, this is directly proportional to the amount of galacturonase present in the fruit, an enzyme that accelerates the degradation of the fruit, making the shelf life of the fruit less to more total nitrogen.

Thus, when comparing the concentrations of total nitrogen, it is observed that sample C has a lower concentration (210 mg/L), being therefore the sample with the lowest amount of galacturonase and, therefore, the one with the longest fruit life after harvest. In addition, it is the one that over time shows a more subdued increase, 9.5%.

Increasingly, sample A shows a total nitrogen concentration of 216 mg/L, and an increase in time of 14.8
Finally, sample B shows a total nitrogen concentration of 386 mg/L and an increase in time of 15.8%.
