This proposal is to support a long-term research program that addresses the global problem of food waste and the growing consumer demand for products with naturally-sourced ingredients. The main objective of the proposed research is to investigate green extraction methods for natural compounds from food processing wastes and develop functional bio-based materials. In this research, the focus will be on pomace, which is a by-product from juice production and is rich in natural pigments.  Natural pigments (e.g. anthocyanins, betalains, lycopene and beta-carotene) are associated with numerous health benefits and are highly-prized ingredients for functional foods, health supplements, and beauty and personal care products. Green extraction/separation methods for biomolecules will be explored using Natural Deep Eutectic Solvents (NADES) and foam fractionation, where the solvent and resultant extract will consist of food and cosmetic-compatible compounds in a water-based system. Then, a novel strategy for producing functional biopolymeric hydrogels from these liquid extracts, where the solvent forms part of the formulation medium, will be established. This research program is innovative as its entire approach is centered on sustainability and the principles of green chemistry: the raw materials for extraction are food processing by-products, the extraction processes are low energy and use natural chemicals that are non-toxic and non-hazardous, and the extracts are incorporated into materials that are biodegradable and produced from natural bioactive compounds and biopolymers. The impact of this research will be significant as it will improve the sustainability of food processing by adding value to food processing byproducts and reducing waste. In addition, the research will develop simpler green extraction technologies for natural pigments and biomolecules that are compatible with food and other consumer products to satisfy the demand for natural clean label products. The use of green extraction technologies and alternative solvents that are bio-based, non-toxic and compatible with food and consumer products will reduce the complexity and cost of existing extraction processes based on conventional organic solvents, while increasing safety and sustainability. By incorporating the green solvents and extracts into bio-based materials, this research program will develop innovative products with increased functionalities for the functional food, nutraceutical, beauty and personal care industries, such as controlled release delivery systems for bioactives and biodegradable active packaging based on calcium-alginate films. This research program will also provide excellent training for highly qualified personnel for the sustained growth of the functional food and natural products industries in Canada, and help to position Canada as a leader in green processing technologies.

该提案旨在支持一项长期研究计划，以解决全球食品浪费问题以及消费者对天然成分产品日益增长的需求。本研究的主要目的是探索从食品加工废弃物中提取天然化合物的绿色提取方法，并开发功能性生物基材料。 本研究的重点将放在果汁生产的副产品果渣上，果渣中含有丰富的天然色素，天然色素（如花青素、甜菜色素、番茄红素和β-胡萝卜素）具有多种健康益处，是功能性食品、保健品、美容和个人护理产品的重要成分。生物分子的绿色提取/分离方法将使用天然深层Eurobenzene溶剂（NADES）和泡沫分馏进行探索，其中溶剂和所得提取物将由水基系统中的食品和化妆品相容性化合物组成。然后，将建立一种新的策略，用于从这些液体提取物生产功能性生物聚合物水凝胶，其中溶剂形成制剂介质的一部分。该研究计划是创新的，因为它的整个方法是以可持续性和绿色化学的原则为中心：提取的原材料是食品加工副产品，提取过程是低能耗的，使用无毒无害的天然化学品，提取物被纳入可生物降解的材料中，由天然生物活性化合物和生物聚合物制成。这项研究的影响将是重大的，因为它将通过增加食品加工副产品的价值和减少浪费来提高食品加工的可持续性。此外，该研究将开发更简单的绿色提取技术，用于天然色素和生物分子，与食品和其他消费品兼容，以满足对天然清洁标签产品的需求。使用生物基、无毒且与食品和消费品兼容的绿色提取技术和替代溶剂将降低基于传统有机溶剂的现有提取工艺的复杂性和成本，同时提高安全性和可持续性。通过将绿色溶剂和提取物融入到生物基材料中，该研究计划将为功能性食品，营养品，美容和个人护理行业开发具有更多功能的创新产品，例如生物活性物质的控释输送系统和基于海藻酸钙膜的可生物降解活性包装。该研究计划还将为加拿大功能性食品和天然产品行业的持续增长提供高素质人才的良好培训，并帮助加拿大成为绿色加工技术的领导者。
