Progress Report Objectives (from AD-416): The objective of the collaboration is to yield a commercially viable, patentable technology to treat select foods with natural, organic powdered antimicrobial treatments that possess acceptable sensory properties. The novel formulations should be effective against foodborne pathogenic bacteria such as E. coli O157:H7, Salmonella enterica, and Listeria monocytogenes. Ideally, the novel formulations would also be effective against spoilage organisms, including fungi. Approach (from AD-416): The approach will include the thorough investigation which could result in proprietary and effective antimicrobial treatments. The treatment possibilities include: Powdered plant treatments. Possible freeze-dried plant powders to be tested include: fruit and vegetable extracts, pomaces, skins, proteins, herbs, seed extracts, powdered fruit and vegetable films, etc., and essential oils incorporated in powdered fruits and vegetables edible films. Possible spray-dried, and fluidized-bed dried microencapsulated powders include active antibacterial and antioxidant agents such as plant essential oils, oil compounds, flavonoids and other phenolic extracts enrobed in maltodextrin and other biopolymers. Progress reported supports paremt project objectives around developing new processes to improve safety and improve quality of specialty crops and their co-products. Novel composite powder and liquid coatings were developed and tested in both model systems and food systems (strawberries and lettuce) for antimicrobial activity. A wide range of compositions were tested and results were compared to the antimicrobial activity of 100 ppm chlorine. Several novel formulations were identified which show promise in controlling Salmonella enterica, Listeria monocytogenes and E. Coli 0157:H7.

Novel composite powder and liquid coatings were developed and tested in both model systems and food systems (baby spinach, cantaloupe, strawberries and sliced apples) for antimicrobial activity. A wide range of compositions were tested and results were compared to the antimicrobial activity of 100 ppm chlorine. Several novel formulations were identified which show promise in controlling Salmonella enterica, Listeria monocytogenes and E. Coli 0157:H7. All parent project objectives were addressed.

Novel powder and liquid coatings have been developed and tested in both model systems as well as on whole foods for their antimicrobial activity. Several formulations and processes are very promising and research continues on this project.

Documents CRADA with Mantrose-Haeuser. Log #39196. Formerly 5325-41000-060-14T; April, 2010. Cantaloupes and strawberries have been coated with antimicrobial surface treatments and some have shown promise in controlling yeast, mold and pathogen growth. Further development of application methods and treatments is needed. This research supports CRIS project objectives in adding value to and improving the quality of fruits and vegetables.

Documents CRADA with Mantrose-Haeuser. Log #39196. Significant Activities that Support Special Target Populations This CRADA with an industrial partner only began recently. We have had several meetings and phone conferences and are beginning the research this month. The research will involve testing various powdered coatings on produce for their antimicrobial activity. Cantaloupes, strawberries and mushrooms will be tested first.
