Food Safety
Assessment of the conditions of different surfaces, including solid, liquid, inert and organic materials, which affect the formation of faults and the growth of microorganisms. Mechanisms that allow the survival of microorganisms on surfaces. Systems for the detection and elimination of rubbing and surface microorganisms. Effectiveness of control systems and interaction between microorganisms. Substances with cleaning and/or biocidal action that prevent or limit the growth of microorganisms on surfaces.

Improvement of Sanitation Systems to Reduce Antimicrobial Resistance and Prevent the Presence of L. monocytogenes on Surfaces in the Food Industry (ARLIM)(PID2022-142329OB-C33)
This project is ongoing and aims to develop alternatives to the use of chemical cleaning products, including natural extracts and microbial competition, in order to achieve surfaces and food production environments that can be more easily controlled, ensuring a reduction in water and energy consumption.

Financed by the Nuclis program of the Generalitat de Catalunya and the company iTram Higiene S.L.We are evaluating new cleaning systems for the breakdown and removal of biofilms. In this case, traditional systems are compared with enzymatic products, already existing on the market, developing new formulas that allow the reduction of disinfectants, reduce aggression to the facilities and the environment. This will reduce water and energy consumption.

Evaluation and validation of the application of new technologies, especially those based on high pressure or curved wave ultraviolet radiation, to ensure the inactivation of pathogens and spoilage microorganisms that can contaminate food, as alternatives to traditional thermal technologies, which are more harmful to the nutrition and functional properties of food.

SafeFood. Development of a new industrial process for obtaining safe, sustainable and higher quality food, through biotechnology and the cybernetic approach. ID: ERA-IB-16-014.
The growth of pathogenic microorganisms in food poses a significant risk, with consequences for the health of consumers, the environment and the economy. Minimally processed foods are increasingly consumed in Europe, but they are susceptible to bacterial growth, including the pathogen Listeria monocytogenes. There are several treatments to eliminate pathogens or limit their growth, but not all of them are suitable for being applied to ready-to-eat foods as they can negatively affect sensory quality. High pressure processing (HPP) is a promising method as it can reduce the number of microorganisms without causing negative effects on food quality. However, it has limited effectiveness as some bacteria, including Listeria monocytogenes, manage to recover from high pressure treatment. The SafeFood industrial biotechnology project is an international project that brings together 8 groups from 6 European countries with the aim of obtaining safer food. The consortium will study what mechanisms allow Listeria monocytogenes to survive and recover after high pressure treatment and what food additives can prevent this.
