Bio-preservant solution to control foodborne pathogens in fresh-cut fruit

Posted by Universitat de LleidaResponsive · Patents for licensing · Spain

Summary of the technology

Our technology is based on a microorganism with demonstrated bio-preservative activity. The strain CPA-7 of Pseudomonas graminis, isolated from fruit, is capable of inhibiting the growth of foodborne human pathogens such as Salmonella, Listeria monocytogenes and Escherichia coli O157:H7 in fresh-cut fruit.

The University of Lleida seeks an industrial partner willing to adopt a new technology for biological control of foodborne pathogenic bacteria in fresh-cut fruit. The type of partner sought is for the regulatory development and commercialization of the protected technology under a license agreement.

Description of the technology

Our technology is based on a microorganism with demonstrated bio-preservative activity. The strain CPA-7 of Pseudomonas graminis, isolated from fruit, is capable of inhibiting the growth of foodborne human pathogens such as Salmonella, Listeria monocytogenes and Escherichia coli O157:H7 in fresh-cut fruit.

Even chemical methods for food disinfection are quite efficient, pathogens can grow again in the foodstuffs during transport and commercialization in ready-to-eat food like fresh-cut fruit and especially if the chill chain is broken. Our new bio-preservant solution is a complementary strategy to chemical methods as it can ensure quality along the whole shelf-life of products, even at low temperatures.

Therefore, our technology prevents the development of new food-borne pathogens, ensures food safety and maintains the product quality throughout the product shelf-life by means of an easy-friendly method.

The solution we provide:

  • Shows effectiveness against the main foodborne pathogens like Salmonella spp., Listeria monocytogenes and Escherichia coli O157:H7 in fresh-cut fruit.
  • Ensures microbiological safety while preserving product quality (appearance, flavor, texture) both at room and cooling conditions (from 5ºC to 20ºC).
  • Can be used as spray or immersion application.
  • Is tested in in vitro conditions for human safety assessment.
  • CPA-7 strain is well-characterized to easy implement laboratory quality controls.
  • Helps for the maintenance of product shelf-life, particularly when the chill chain is broken.
  • Is compatible with current manufacturing technology in the industry of fresh-cut products.

Applications

Its use in the fruit industry, particularly in minimally processed fruit, prevents the development of food-borne pathogens, ensures food safety and maintains the product quality by means of an easy-friendly method. In addition, this technology could be useful for the same application in other ready-to-eat foodstuffs.

Current development status

Finished technologies - Our CPA7 technology is validated under commercial simulated conditions against several foodborne pathogens (Salmonella, E.coli O157:H7 and L. monocytogenes), temperatures (5, 10 and 20 ºC) and fresh-cut fruits.
