Development of an optimized pilot-scale process for extraction and purification of polyphenols contained in residual leaves of cranberry

公司‘’VIVACO Groupe Coopéatif‘’(ViVCO)于2015年在加拿大昆士兰州维多利亚维尔成立，由La Coop des Appalaches和La Coop des Bois-Francs合并而成。ViVaco在五个主要部门开展业务：翻新中心、便利店、农业和建筑机械、动植物生产(包括碾磨和谷物服务)，最后是杂货。在企业的活动中，有机食品生产是一个战略性部门。此外，ViVaco还对在温和的操作条件下从蔓越莓叶等残渣中提取高附加值化合物感兴趣。据报道，蔓越莓叶中含有大量的多酚类物质。将优化提取的操作条件，并将开发多酚的提纯，以获得可用于动物饲料、保健和饮料等部门的配方。最后，在该项目的框架内，将进行技术经济分析，以确定蔓越莓叶的有价化是否可行。该项目的重点是零浪费的概念，通过探索农业食品生物质的有价化。此外，该项目将有助于发展绿色化学，并对通常送往堆肥或垃圾填埋场的剩余生物质进行评估。

The company ''VIVACO groupe coopératif'' (Vivaco) was established in 2015 at Victoriaville (QC, Canada) following the fusion of La Coop des Appalaches and La Coop des Bois-Francs. Vivaco operates in five main sectors: renovation centers, convenience stores, agricultural and construction machinery, animal and vegetable production including milling and grain services and finally grocery. Among the activities of the enterprise, the production of organic food is a strategic sector. Furthermore, Vivaco is interested in the extraction of high value-added compounds from residual waste, such as cranberry leaves, under mild operating condition. It is reported that cranberry leaves contain polyphenols at high quantity. The operating conditions of extraction will be optimised, and the purification of polyphenols will be developed to obtain formulations which can be used in sectors such as animal feed, health care and beverages. And finally, in the frame of this project a techno-economic analysis will be performed to determine if the valorisation of cranberry leaves is feasible.The project focuses on the zero waste concept, by exploring the valorization of agri-food biomasses. In addition, this project will help to develop green chemistry and to valorize residual biomass which is commonly sent to compost or landfills.
