This work aimed to dimension a processing line for the extraction of pectin from passion fruit peels to the scale-up of an industrial pulp and juice processing plant. Taking into account that a medium-sized industry in Brazil processes 3,000 tons of passion fruit annually, the production of pectin was 23,934.24 kg·year-1, under the extraction conditions of 80 °C, 52.5 min, and 0.0002 mol·L-1 of citric acid. The process includes unit operations such as solid-liquid extraction, filtration, drying, and grinding of the pectin. The calculations of mass balance, energy balance, and the dimensioning of the equipment were made from data provided by the literature and by equipment suppliers. The results achieved help in the implementation of this process on an industrial scale.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
