Report on physical, chemical and microbiological characteristic of rest raw materials (RRM) and wash water (WW)

Abstract

This report is a part of ReValue project and present the outcomes from activities within WP2 Valorization techniques. Deliverable D2.1. "Report on physical, chemical and microbiological characteristic of rest raw materials (RRM) and wash water (WW)" covers physical, chemical and microbiological characteristic of RRM)and WW used in the project for development and optimisation several technological solutions for better utilisation of valuable materials often considered as waste due to improper handling followed by lose of the quality. This deliverable indicates physical, chemical and microbiological characteristic of RRM) and WW collected and analysed in Norway, India and Spain. The work performed at CFTRI (India), AMITY (India), SINTEF/NTNU (Norway) and LEITAT (Spain). Performed tests and analyses indicated that different RRM obtained from surimi processing factories has a potential to be used as valuable ingredients in different formulations (both food and feed marked). Some variation in chemical composition as well as microbial quality gives indication that proper storage and handling methods and optimal processing technologies need to be applied in order to produce high quality final products. Summarised it can be stated that all analysed RRM obtained from surimi processing are rich in proteins (40-80 % of dry material) and are good source for production of protein rich products and ingredients.
