Knowledge Of Food Safety And Food Handling Practices Amongst Food Handlers In The Republic Of Ireland, Nora A. Moreb, Anushree Priyadarshini, Amit Jaiswal

Articles

Food safety concerns have existed for a long time, as millions of people across the globe suffer from food borne disease every year. Contamination of food owing to limited knowledge of food safety practices primarily increases the risk of food borne illnesses. In the present study, quantitative research was carried out to gauge the level of food safety knowledge amongst people living in Ireland. A total of 1069 participants from all over the Republic of Ireland contributed to the survey (of which 821 were included in this research). Results showed that the residents of Ireland overall had an average levelonknowledge …

Seaweed Carotenoid Fucoxanthin As Functional Food., Nissreen Abu-Ghannam, Emer Shannon

Books/Book Chapters/ Proceedings

Fucoxanthin is a bioactive compound found in one of the most prolific and sustainable organisms on the planet, alga. Its efficacy and potential in terms of health applications have been widely reported in clinical studies. Technical modifications, such as encapsulation, and sensory trials must be undertaken before fucoxanthin can be successfully utilised as a functional food ingredient. Factors to consider include solubility in the food matrix, organoleptic effects, stability, preservation against oxidation, consumer acceptability, bioavailability, and toxicity risk. Possible solutions may include the development of more efficient and greener extraction technologies, which require shorter extraction times and less solvent, and …

Controlling Brochothrix Thermosphacta As A Spoilage Risk Using In Package Atmospheric Cold Plasma, Apurva Patange, Daniela Boehm, Carmen Bueno-Ferrer, Patrick Cullen, Paula Bourke

Articles

Brochothrix thermosphacta is a predominant spoilage microorganism in meat and its control in processing environments is important to maintain meat product quality. Atmospheric cold plasma is of interest for control of pathogenic and spoilage microorganisms in foods. This study ascertained the potential of dielectric barrier discharge atmospheric cold plasma (DBD-ACP) for control of B. thermosphacta in response to key parameters such as treatment time, voltage level, interactions with media composition and post treatment storage conditions. Challenge populations were evaluated as suspensions in PBS, as biofilms in meat model medium and surface attached on raw lamb chops under MAP.

Achieving Reactive Species Specificity Within Plasma Activated Water Through Selective Generation Using Air Spark And Glow Discharges, Paula Bourke, Patrick Cullen, Peng Lu, Daniela Boehm

Articles

Plasma activated liquids (PAL) attract increasing interest with demonstrated biological effects. Plasma exposure in air produces stable aqueous reactive species which can serve as chemical diagnostics of PAL systems. Here, we tailor aqueous reactive species inside plasma activated water (PAW) through treating water with AC air spark and glow discharges in contact with water. Chemical probing demonstrated species specificity between two types of PAW. Spark discharge PAW contains 2 2 H O and 3 NO , while 2 NO and 3 NO are generated in glow discharge PAW. Species formation in different PAWs have been discussed in terms of discharge …
