Three‐stage sequential extraction of anthocyanins, polyphenols, and pectin has the potential to enhance the product's functional properties and the economic value of mango (Mangifera indica L.) peels beyond the two‐stage processes (anthocyanin‐pectin and polyphenol‐pectin). A three‐stage process was developed by incorporating a polyphenol extraction stage in a sequential process where anthocyanins and pectin were co‐extracts. Anthocyanins were extracted first (80% ethanol (EC)/2% acetic acid/25 °C/1 h), generating a residue from which polyphenols were extracted (65–85% EC/20–80 min/70 °C), based on a full factorial statistical experiment. Pectin was subsequently extracted from the second‐stage residues (0.25% ammonium oxalate / oxalic acid / 85 °C / 1 h). The economic benefits (net present value (NPV), payback period (PBP), product minimum selling price (PMSP) of the three‐stage sequential process (anthocyanin, polyphenol, and pectin) and the two‐stage processes (anthocyanin‐pectin and polyphenol‐pectin) were evaluated over a plant life of 25 years. Polyphenols and pectin from the three‐stage process had >65% higher antioxidant capacity and up to 10.4% higher purity, respectively, when compared with those from the two‐stage processes. There is also more economic gain from the three‐stage process (NPV −$4 31 285, PBP −3 years, PMSP < $10/kg) than the anthocyanin‐pectin process (NPV −$3 76 917, PBP −3.22 years, PMSP < $10/kg) and the polyphenol‐pectin process (NPV −$235 599, PBP −4.29 years, PMSP < $30/kg). Thus, three‐stage sequential extraction is an economic process, which enables the recovery of three value‐added food ingredients with improved functional properties from mango peels.© 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

芒果皮的三阶段和两阶段顺序增值的理化性质和经济收益的比较

花青素,多酚和果胶的三步顺序萃取有可能提高产品的功能特性和芒果的经济价值(Mangifera indica)L.)剥离超过两个阶段的过程(原花青素果胶和多酚果胶)。通过将多酚提取阶段与花青素和果胶为共提取物的顺序过程相结合,开发了一个三阶段过程。首先提取花青素(80%乙醇(EC)/ 2%乙酸/ 25°C / 1 h),产生残留物,从中提取多酚(65-85%EC / 20-80 min / 70°C),基于完整的阶乘统计实验。随后从第二阶段残留物中提取果胶(0.25%草酸铵/草酸/ 85°C / 1 h)。三阶段顺序过程(花色素苷,多酚,和果胶)和两个阶段的过程(花青素果胶和多酚果胶)在植物的25年寿命中进行了评估。与来自两步法的多酚和果胶相比,来自三步法的多酚和果胶的抗氧化能力分别高出65%以上和高达10.4%的纯度。通过三阶段流程(NPV − $ 4 31 285,PBP −3年,PMSP <$ 10 / kg)也比花青素-果胶流程(NPV − $ 3 76 917,PBP −3.22年,PMSP < $ 10 / kg)和多酚果胶工艺(NPV-$ 235 599,PBP -4.29年,PMSP <$ 30 / kg)。因此,三阶段连续萃取是一种经济过程,可以从芒果皮中回收三种具有改善的功能特性的增值食品成分。©2020年化学工业协会和John Wiley&Sons,Ltd 与两步法相比,其抗氧化能力分别提高了65%和纯度提高了10.4%。通过三阶段流程(NPV − $ 4 31 285,PBP −3年,PMSP <$ 10 / kg)也比花青素-果胶流程(NPV − $ 3 76 917,PBP −3.22年,PMSP < $ 10 / kg)和多酚果胶加工工艺(NPV-$ 235 599,PBP -4.29年,PMSP <$ 30 / kg)。因此,三阶段连续萃取是一种经济过程,可以从芒果皮中回收三种具有改善的功能特性的增值食品成分。©2020年化学工业协会和John Wiley&Sons,Ltd 与两步法相比,其抗氧化能力分别提高了65%和纯度提高了10.4%。通过三阶段流程(NPV − $ 4 31 285,PBP −3年,PMSP <$ 10 / kg)也比花青素-果胶流程(NPV − $ 3 76 917,PBP −3.22年,PMSP < $ 10 / kg)和多酚果胶工艺(NPV-$ 235 599,PBP -4.29年,PMSP <$ 30 / kg)。因此,三阶段连续萃取是一个经济过程,可以从芒果皮中回收三种具有改善的功能特性的增值食品成分。©2020年化学工业协会和John Wiley&Sons,Ltd $ 10 / kg)比花青素-果胶工艺(NPV − $ 3 76 917,PBP −3.22年,PMSP <$ 10 / kg)和多酚果胶工艺(NPV − $ 235 599,PBP −4.29年,PMSP <$ 30 / kg )。因此,三阶段连续萃取是一种经济过程,可以从芒果皮中回收三种具有改善的功能特性的增值食品成分。©2020年化学工业协会和John Wiley&Sons,Ltd $ 10 / kg)比花青素-果胶工艺(NPV − $ 3 76 917,PBP −3.22年,PMSP <$ 10 / kg)和多酚果胶工艺(NPV − $ 235 599,PBP −4.29年,PMSP <$ 30 / kg )。因此,三阶段连续萃取是一种经济过程,可以从芒果皮中回收三种具有改善的功能特性的增值食品成分。©2020年化学工业协会和John Wiley&Sons,Ltd
