Brazil is the world’s largest producer of oranges and the largest juice exporter of this fruit. Due to this high productivity of juices, and considering that about 50% of all the raw material is transformed into a by-product of the processing, the Brazilian industries generate millions of tons of these annually. Among the byproducts of orange juice pectin is highlighted due to its large quantity and huge versatility of use. Thus, the objective of this work was to evaluate the influence of temperature (70, 80 and 90 ° C), extraction time (80, 120 and 160 minutes) and logarithm of extraction acid concentration (0.176, 1.176 and 2.176 mol.L- 1) in pectin yield using citric acid for the acid hydrolysis extraction of byproducts from the juice industry of Citrus sinensis L. The results indicate that pectin yield ranged from 5.91% to 34.36%. In the pectin extraction conditions studied, the optimum condition was a temperature of 70 ° C, extraction time of 80 minutes and a logarithm of the acid concentration of 2,176 mol L -1. The only variable that showed influence in the conditions analyzed was the logarithm of the acid concentration (p <0,05), demonstrating that the pectin yield is directly proportional to the acid concentration in the extraction solution. |
