Transforming agricultural by-products into sustainable protein sources.
SAN-PROT valorises olive oil the residue from olive oil extraction, known as sansa, as a new alternative protein source, addressing the challenges of the protein transition.
In a context in which the demand for proteins will grow significantly until 2050, and with the increasing environmental pressures derived from animal production, SAN-PROT proposes a sustainable solution that reduces dependence on traditional sources such as soy and promotes more environmentally responsible production.
The project takes advantage of the residue generated during the extraction of olive oil to develop new protein applications with added value. To achieve this, SAN-PROT identifies and characterises the protein content of the sansa of various olive varieties, studies its recovery and concentration through innovative processes such as solvent extraction, enzymatic hydrolysis and solid-phase fermentation, and evaluates the nutritional quality of the recovered protein.
One of the key aspects of the project is the application of this protein in pig feed formulations, with the aim of improving the diet of piglets and optimising the production parameters of the pig sector. In addition, the project places special emphasis on ensuring the nutritional quality of alternative proteins, especially for consumers in critical stages such as growth or aging.
With a multidisciplinary and collaborative approach, SAN-PROT offers a solution that optimises existing resources, promotes environmental sustainability and strengthens the resilience of the agricultural and livestock industry. This initiative highlights agricultural by-products, demonstrating their potential to contribute to a more sustainable and efficient food system.
Eurecat is the technical coordinator of the project, through the Nutrition and Health Unit.
