postharvest agrotecnio

 

Goals

• New biocontrol agents and physical/chemical treatments for postharvest preservation of fruits and vegetables
• Identify and control microbial hazards of fresh, minimally-processed and processed fruits and vegetables and to develop new strategies for their reduction and control to ensure food safety without affecting quality (standard, nutritional and sensorial)
• To elucidate the factors that modulate the interaction between compatible and non-compatible host-pathogen relations (P.digitatum and P.expansum-oranges and apples) using molecular, pathological and biochemical approaches

Research Lines

• Develop new biocontrol agents and physical/chemical treatments to control postharvest diseases in fruits.
• Study of the microbial hazards and risks of fresh and minimally-processed fruits and vegetables
• Study of the interaction host-pathogen-environment.
Main activities
• Evaluation of biological control agents in the laboratory and pilot plant
• Study of Preharvest risks factors affecting safety of MFPF.
• Study the incidence and survival of foodborne pathogens on MPFV.
• Study of new or alternative methods to reduce and control the growth of spoilage microorganisms and foodborne pathogens.
• Analysis of expression of genes involved in defences responses of apples inoculated with the pathogen P. expansum and non-pathogen P. digitatum
• Proteomic analysis of apple proteins differentially expressed in response to the pathogen P. expansum and non-pathogen P. digitatum.

International impact

The development of techniques to reduce or control the growth of FBPs on fresh-cut fruits based on the use of one antagonist, Pseudomonas graminis CPA-7, that has shown high efficacy in reducing foodborne pathogens responsible of foodborne diseases (Salmonella spp., E.coli O157:H7 and Listeria monocytogenes) in fresh-cut fruits.
