Valorization of Organic Materials from Food Industry Sidestreams

Within valorization of side streams and under-utilized products from the food and and agricultural industries, our competence involves a global approach with four sub-areas: pre-treatment, separation, characterization, and ingredient design for tailored product applications.

Our main strength lies within the broad experience of working with a wide range of materials and technologies, allowing us to identify the best approach for each project and application area. Supporting analytical and characterisation capacities allows us

Protein separaton, fermentation and supercritical CO₂ extraction of bioactive compounds are among our main strengths. Where we can optimise process conditions or apply combinations of processes to obtain improved yields of functional products.

Pre-treatment

Drying and milling
Fractionation
Microwave, PEF and high power ultrasound
Fermentation
Enzymatic treatments
Thermo-mechanical processing

Separation

Extraction of polar / nonpolar bioactive compounds
- Supercritical CO ₂ extraction with / without co-solvents
- Pressurized liquid extraction
Fractionation
Protein isolation
Enzymatic treatments

Characterization

Yield analysis
Functional properties
Total phenolics & flavanols content
Antioxidant activity and profile
Protein content
Protein properties - size, thermal behaviour and chemical properties
Fatty acids profile
Antinutrient contents, such as phytate and tannins

Towards Product Design...

The choice of technique and process conditions can significantly alter the composition and properties of the resulting ingredient. By understanding the influence of these different factors, the behaviour of the target ingredient can be optimised for specific product applications - maximising its value, increasing resource efficiency, and even opening up new markets.

That could be optimising pre-treatment and extraction of a protein ingredient to yield something with a high solubility and neutral taste for plant-based beverage applications, or modification of fiber based materials to change the properties of the ingredient towards certain product areas like baking ingredients.

RISE's wide ranging expertise in ingredient manufacturing and product development can us support with process design and optimisation to maximise the value of your side-streams.
