Process development and simulation of pectin extraction from orange peels
This work presents the sizing and scheduling of a semi-batch plant for the production of 348
ton/year of pectin from Valencia orange peels under optimum experimental extraction
conditions (90° C, 75 min, pH 1.5). The designed plant included acid hydrolysis of peels,
filtration of the hydrolyzed suspension, alcoholic precipitation of pectin, gel pressing, gel
drying, and pectin size reduction. Calculations of processing times and size of units were
done with Microsoft Excel® and Aspen Plus v7. 3®. Characteristic dead times in the …
