Project Start: 1. Jul. 2017
Project End: 1. Mar. 2019

ReValue will contribute to achieving the SDG target on food losses reduction, by developing innovative technologies for Surimi industry, namely reducing losses by improved cold chain management and efficient conversion of RRM and wash water into value added protein and oil ingredients for food and feed applications. Globally, fish losses account for 160.000.000 tonnes/year, out of which the Surimi industry is responsible for more than 3.5%. In order to use these RRM into value added ingredients for food and feed applications, proper management is required to preserve their quality. Because of the high content of proteins, lipids and other valuable compounds, these RRM are highly valuable from a nutritional, environmental and socio-economic point of view. Enzymatic hydrolysis is an efficient biotechnological solution that can be applied to extract marine proteins and lipids from RRM. Commercial enzymes and high temperatures are commonly used for RRM processing. However, fish RRM contain a variety of endogenous enzymes (cost free) that represent a readily available enzymatic biorefinery tool for fractionation and modification of fish RRM and allowing processing at milder conditions, which is a novel approach for fractionation of proteins and lipids from RRM.

ReValue will characterise and adapt endogenous enzymes, determine enzymatic activity and define processing conditions, thus improving the bioeconomy of the process. RRM are rich in marine phospholipids (MPL), containing omega-3 fatty acids that are interesting due to their potential higher bioavailability. Thermal extraction or enzymatic hydrolysis of RRM leads to upconcentration of MPL in the non-soluble fraction which could be used for extraction of MPL. It can serve as a starting material for residual protein (gelatine) extraction with novel extraction methods. Concepts for efficient supply chain management including cold chain management and climate friendly refrigeration also need further development to meet the challenges related to maintaining the quality of RRM so that they can be utilized into high value added products. A high market and economic impact will be achieved through strengthening the competitiveness of the Industrial Partners in the target market sectors and related ones by:

  1. promoting the use of ReValue materials, components and systems in high value-added applications while keeping costs competitive.
  2. strengthening and differentiating the EU and Indian Industry.
  3. increasing workers’ skills.

development and demonstration.
