Resumen:
Una universidad española ha desarrollado una nueva tecnología de control biológico de bacterias patógenas que se transmiten por los alimentos en frutas recién cortadas. Esta tecnología garantiza la seguridad de los alimentos y mantiene la calidad del producto durante toda su vida útil gracias a un método de fácil manejo. La cepa CPA-7 de Pseudomonas graminis, aislada de la fruta, es capaz de inhibir el crecimiento de patógenos humanos transmitidos por alimentos, como Salmonella, Listeria monocytogenes y Escherichia coli O157:H7 en fruta recién cortada. La universidad busca industrias con el fin de establecer acuerdos de licencia o cooperación técnica.

Tittle:
Bio-preservative solution to control foodborne pathogens in fresh-cut fruit
Summary:
A Spanish university has developed a new technology for biological control of foodborne pathogenic bacteria in fresh-cut fruit that ensures food safety and maintains the product quality throughout the product shelf-life by means of an user-friendly method. They are looking for partners from the industry interested in a license agreement or a technical cooperation agreement.
Description:
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.

A Spanish university has developed a technology 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 new solution developed is a complementary strategy to exixting chemical methods as it can ensure quality along the whole shelf-life of products, even at low temperatures.

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

This technology is compatible with current manufacturing technologies in the industry of fresh-cut products as it can be used in immersion application.

The developed technology is validated under commercial simulated conditions against the main foodborne pathogens (Salmonella, E.coli O157:H7 and L. monocytogenes), temperatures (5, 10 and 20 ºC) and fresh-cut fruits.

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 user-friendly method.

In addition, this technology could be useful for the same application in other ready-to-eat foodstuffs.

The Spanish university is interested in a license agreement with partners from the food industry that can industrialize and bring to the market this technology. The partners sought are expected to carry out the regulatory development required for the commercialization of this technology.

They are also interested in a technical cooperation agreement when further development to adapt to client specific needs may be required.
Advantages and Innovations:
· Shows effectiveness against the main foodborne pathogens such as 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).
· Is tested in in vitro and in vivo 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.

Partner sought

Type and Role of Partner Sought:
The Spanish university is looking for industrial partners working in the production and/or formulation of microbial cultures for the food industry. Fresh-cut fruit and other ready-to-eat foodstuffs producers could be also potential partners.

The collaboration should succed by means of a licence agreement wehre the partner sought should take care of regulatory development as well as the commercialization of the protected technology.

The cooperation could also succed via a technical cooperation agreement when a further development to adapt the technology to the client or the market specific needs is required.
