Voluminous side streams are generated during animal and plant-based food processing. These particular side streams are interesting because of their valuable content (complex carbohydrates, proteins, polyphenols, and lipids, amongst others) which can be used for further valorisation. According to the European Commission, most of these side streams are produced by the food manufacturing sector, and by 2020 it is expected to rise to 126 million tons compared to 96 million tons generated in 2007. Research on producing/recovering valuable products from these side streams is being done around the world however, the use of these side streams is limited due to public acceptance, uncertainty on composition and quality. Adsorption is a powerful technique that allows separation of complex mixtures and can be operated at mild conditions. Applying adsorption might lead to a higher purity of the wanted product and reduce the impact on functional properties and nutritional value produced by thermal or physicochemical processes. This paper will present High Throughput Screening (HTS) experimentation results used to evaluate different adsorbents to selectively capture the target compounds. Adsorption capacity, selectivity and ease of desorption are considered to define a resin selection criterion for evaluating the different absorbents. Moreover, different models on contacting modes (fixed bed and continuous chromatography) will be evaluated to capture valuable compounds from food side streams. The resins selected will be used for large scale chromatographic process design.
