Identification of nut-derived probiotic bacteria with antioxidant and anti-inflammatory benefits
In this project developed for Importaco, a company specialising in the commercialisation of nuts, we have identified three probiotics of the Lactobacillus and Pediococcus genera found in the nuts themselves, which have antioxidant, anti-inflammatory and immunostimulant activity according to in vivo and in vitro studies carried out. These activities represent potential therapeutic targets that open up the possibility of developing solutions suitable for preventing cellular ageing and stimulating the anti-inflammatory response.
The study began in 2020 by analysing the microbiota of more than 50 samples of nuts from different origins, with the aim of isolating and characterising microorganisms with potential positive health effects. Following this process, we cultured and characterised three probiotic strains based on: their safety, their resistance to passage through the gastrointestinal tract, and their ability to adhere to the intestinal epithelium and inhibit pathogens.
The result? The revaluation of a product that already had very interesting properties, as Importaco has developed a range of advanced food products made up of almonds and walnuts enriched with these probiotics. These products combine the benefits of nuts as a source of calcium and omega 3 with the probiotic properties of the selected microorganisms.
“This project is the beginning of a line of innovation associated with research applied to improving people’s health. We are very committed to science because we believe that it is the best way to respond to the challenges we face as a society,” says Teresa Cercós, Importaco’s general manager for innovation, quality and the environment.
