Vision: Assuring healthy, nutritious and safe food through excellence in research

Department's Activity
Research activity in the Department of Food Quality and Safety is aimed at assuring healthy, nutritious and safe food for consumers.
Scientists in the department use cutting-edge technologies and approaches in order to gain these goals through integrative and interdisciplinary studies. The specific research activity involves three thematic areas:
(a) Minimizing losses of fresh produce and stored grains
(b) Microbial food safety
(c) Functional food, food additives and nutraceuticals

Minimizing losses and improvement of food and feed quality
• Chemical approaches for the development of active packages and natural edible coating for extension of shelf life fresh fruits and vegetables
• Active edible coatings to prolong storability and to enhance quality of fresh agricultural products
• Smart and active biodegradable packages for food storage
• Development of the next generation of insect specific bio-rational insecticides with enhanced safety utilizing pheromones, hormones and neuro-bioactive compounds and targeting the reproductive potential of pest insects
• Development of monitoring systems for pest insects of stored food and feed products
• Development of technological and bio-control methods (Fumigation, Phyto-chemicals, Pheromones, IGRs, Inert dusts) for mitigation of pest insects in stored grains
• Study of Eurygaster integriceps and wheat grain bread-making quality
• Quarantine treatments for cut flowers, fresh spices and dates
• Development of natural polymers-based systems for delivery of beneficial components to food products
• Improving silage preparation and the usage of by-product as potential nutritious feed
• Understanding factors affecting spoilage of food (milk and dairy products, fish and other aquaculture products)

Microbial food safety
• Development of novel surface coatings preventing microbial colonization
• Development of safe 'contact active' antimicrobial surfaces to prevent food cross-contamination and biofilm formation
• Understanding mechanisms and environmental conditions associated with growth of mycotoxigenic fungi and the production of mycotoxins in agricultural commodities, processed food and feed
• Development of methods and technologies for the reduction or elimination of mycotoxins in agricultural commodities
• Understanding persistence mechanisms of foodborne pathogens (Salmonella, E. coli, Bacillus cereus) along the food chain
• Elucidation of contamination routs and mechanisms in the field and the food industry

Functional food, food additives and nutraceuticals
• Screening and identification of health-promoting molecules in plants grown in arid- and semi-arid regions
• Development of strategies and means to augment the content of health-promoting molecules in crops by either pre-harvest or post-harvest treatments
• Elucidation of metabolic pathways leading to the synthesis and accumulation of health-promoting molecules
• Providing knowledge and support for researchers and breeders towards bio-fortification of crops.
• Development of unconventional systems for encapsulation and controlled release of nutraceutic agents
• Research and development of phytochemicals and plant extracts as drugs, functional foods, food additives  for the prevention and/or treatment of neurodegenerative diseases.

• Research and development of phytochemicals and plant extracts as drugs, functional foods, food additives for the prevention and/or treatment of chronic diseases.

Contribution to Agriculture
• Development of active packages and natural edible coating for extension of shelf life and improving the safety of fresh fruits and vegetables
• Development and application of inspection tools and treatment for minimizing losses in grain storage
• Preservation of wheat-grains quality by monitoring and developing of technological and biological control methods
• Improving ensiling technology of forage crops; utilizing by-products for ruminant feeding.
• Applicative projects solving ad-hoc problems in feed centers
• Development of a model system for assessment cleaning and disinfection efficacy of surfaces in the dairy industry
• Development of molecular methods for monitoring microbial colonization on surfaces
• Identification of the therapeutic potential of Israel's wild plants and their development as future functional crops
• Development of quarantine treatments for cut flowers, fresh spices and dates.
