Circular-based alternative protein extraction from grape seeds

PROSEED is a European project that aims at the production and commercialisation of a new alternative protein product.


The project will valorise grapevine seeds, an abundant wine industry by-product, into a high-value nutritional ingredient to be used as an additive in the healthy food and non-alcoholic beverages industry.


The production of this new alternative protein addresses the primary issue of acute protein production deficit in the European Union and enables the application of a circular economy model within the wine value chain.


The extraction and use of the novel ingredient will be able to replace animal-based protein use and support the creation of new, more sustainable supply chains with significantly smaller environmental footprints. A comparison between the animal-based protein production and the PROSEED grape seed protein production shows that an 82% reduction of CO2 emissions is possible.


Yes, the protein that is extracted from the grape seeds is by definition gluten-free. During the extraction and production process no gluten-based products or ingredients have been used.


Caviro SCA and Caviro Extra have designed a protein extraction bioprocess based on a pilot grape seeds detannification process that utilises Ultrasound Assistant Extraction (UAE) – specifically Alkaline – Acidic Extraction (AAE) coupled with ultrasound technology – with the goal to scale the technology up to industrial level within 2024.
