Taking into account that the industrial processing of passion fruit generates significant amounts of waste (only the peels represent 51% of the total mass of the fruit), in the present study an economic analysis was conducted to evaluate industrial line viability for pectin extraction from passion fruit peels. Knowing that absolute ethanol (99.50% purity), used in the precipitation and washing steps, has a higher cost, a simulation of extractive distillation was performed using solvents ethylene glycol and glycerol, in the software Aspen Plus v.11, being possible to recover 99.63% of ethanol for both solvents. The results of the economic evaluation showed that the process using ethylene glycol has an advantage, mainly due to its higher profitability (1.13 times higher), lower production cost (94.86% of the price using glycerol), and a lower breakeven point (around 3% smaller). The financial indicators showed profitability and attractiveness for the implementation of this processing line.
考虑到百香果的工业加工会产生大量的废物（仅果皮就占果实总质量的 51%），本研究进行了经济分析，以评估从百香果果皮中提取果胶的工业生产线的可行性。由于在沉淀和洗涤步骤中使用的 99.50%纯度的绝对乙醇成本更高，因此在 Aspen Plus v.11 软件中使用乙二醇和甘油作为溶剂进行了萃取精馏模拟，可以回收两种溶剂中 99.63%的乙醇。经济评估的结果表明，使用乙二醇的工艺具有优势，主要是因为其盈利能力更高（高 1.13 倍）、生产成本更低（使用甘油的价格低 94.86%）和平衡点更低（小约 3%）。财务指标表明，实施这条加工线具有盈利性和吸引力。
