| Abstract | ||
| This study examined the antimicrobial properties of thyme and cinnamon extracts in relation to the microbial quality and shelf-life of beef. Beef samples were randomly sourced from various supermarkets and butcher shops in the Menoufia Governorate, Egypt. Samples were categorized into three groups: a control group with no treatment, a group treated with 1% thyme extract, and another treated with 1% cinnamon extract. The microbial quality of beef was evaluated by assessment the total bacterial counts, coliform counts, and staphylococcal counts over a 15-day storage period store at 4°C. The results indicated that both thyme and cinnamon extracts significantly inhibited Bacterial growth compared to the control group. Specifically, thyme-treated samples demonstrated a decrease in total colony count from 6.5±0.06 on day one to 4.7±0.03 by day nine, while cinnamon-treated samples exhibited a reduction from 6.17±0.07 to 3.1±0.04. Sensory evaluations revealed that thyme-treated samples maintained acceptable quality for up to three days, whereas cinnamon-treated samples remained acceptable for up to nine days. These findings suggest that thyme. | ||
