The organic acids and polyphenol in cranberry juice and citrus extract would alter the viral protein and help inhibit its activity.<\/p>\n\n\n\n<p>\u201cNoroviruses usually require an irradiation dose of three kilograys (kGy), but we have shown that the treatment time is reduced by half with this fruit mixture spray, which acts as a natural antimicrobial. Using these natural antimicrobials prevents cell breakdown or brown discolouration,\u201d reports Monique Lacroix, lead author on the study whose&nbsp;<a href=\"https:\/\/sfamjournals.onlinelibrary.wiley.com\/doi\/full\/10.1111\/jam.14596?af=R\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"broken_link\">results<\/a>&nbsp;were published online on February 12 in the&nbsp;<a href=\"https:\/\/sfamjournals.onlinelibrary.wiley.com\/\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"broken_link\"><em>Journal of Applied Microbiology<\/em><\/a>.<\/p>\n\n\n\n<p>Professor Lacroix\u2019s team is the first to test the cranberry juice and citrus extract mixture in a combined treatment. \u201cBoth the juice and extract have the ability to remove noroviruses when used alone, but when combined with cold pasteurization in the same treatment, the fruit concentrations required are significantly lower,\u201d says the food science expert.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Norovirus Contamination<\/strong><\/strong><\/h2>\n\n\n\n<p>Norovirus contamination can occur before and after harvest. Contaminated water runoff from fields can bring in fecal matter. Food can be contaminated by infected people who handle it.<\/p>\n\n\n\n<p>\u201cUnlike bacteria, noroviruses do not multiply on food. They are deposited there and remain there until a human being is infected,\u201d says Alexandra Gobeil, first author of the study and a recent master\u2019s graduate in Applied Microbiology at INRS.<\/p>\n\n\n\n<p>Monique Lacroix and her team have tested the coating on lettuce, one of the most fragile vegetables in terms of preservation. She hopes to eventually develop a partnership with the food industry to test combinations of treatments involving natural fruit extracts and cold pasteurization (e.g., UV-C, X-ray, gamma ray, or ozonation) on a commercial scale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>About the study<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"has-small-font-size\"><a href=\"https:\/\/sfamjournals.onlinelibrary.wiley.com\/doi\/full\/10.1111\/jam.14596?af=R\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"broken_link\"><em>Radiosensitivity increase in FCV-F9 virus using combined treatments with natural antimicrobials and c-irradiation<\/em><\/a>&nbsp;by A.
