Physico-Chemical quality of minced beef marketed by the delivery system in the municipality of Niterói, RJ: A case study during the COVID-19 Pandemic

Abstract

The research aimed to evaluate the physical-chemical quality of ground beef marketed by the delivery service of two supermarkets in the municipality of Niterói in the pandemic period of Covid 19, between June 2020 and March 2021. They were selected and immediately sent to the Physical-Chemical Control Laboratory of the Veterinary Faculty of the University Federal Fluminense to carry out physical-chemical analyzes (pH, NH₃, H₂S, proof of cooking, filtration and cadaverine), thirty-one (n=31) samples of ground beef with change in odor and color during receipt. The results of these analyzes showed that 100% of the samples sold did not meet the quality parameters for the product. It was also found that the physical-chemical analyzes were important as confirmatory evidence of sensory changes in color and aroma, confirming the indications of product deterioration. Finally, the need for greater monitoring of the health risks of delivery systems by inspection bodies is highlighted in order to preserve the health of their users. It is also recommended that training courses in the food delivery segment be promoted by Organs responsible bodies.
