Detection of Visible and Invisible Fecal Contamination on Chicken Carcasses Using Multispectral Fluorescence Imaging and Machine Learning to Mitigate Salmonella Risks.

Salmonella, mainly associated with raw poultry, remains a major food safety concern as the number of illnesses have not reduced over the past decade warranting a need for convergent, disruptive approaches. In poultry processing plants, the USDA-FSIS implements a "zero visible fecal tolerance" policy on eviscerated broiler carcasses entering the chiller as a step to reduce the pathogen from cross contamination. The efficacy of multispectral fluorescence imaging technology to detect visible and invisible fecal matter from different sections of the gastrointestinal tract was assessed on 404 carcasses to enhance automation in processing plants.

-Alkyl derivatives of ferulic and syringic acid as lipophilic antioxidants: effect of the length of the alkyl chain on the improvement of the thermo-oxidative stability of sunflower oil.

Lipid oxidation is the major cause of the deterioration of fat-containing foods, especially those containing polyunsaturated fatty acids (PUFAs). Antioxidant additives of synthetic origin are added to matrices rich in PUFAs, such as sunflower oil (SO). However, there is controversy regarding their safety, and their low solubility in both water and fat has led to the search for new covalent modifications through lipophilicity.
