Retail stores often offer discounts on purchases of large amounts of meat. Some of the meat is prepared the same day, and some is stored for later use. This study evaluates the effect of retail packaging, freezing and thawing on the quality of beef patties. Loosely ground beef was retail-packed in: (1) highly permeable wrap, and (2) high oxygen MAP. The meat was subsequently refrigerated at 4°C...

The aim of the present study was to develop an electronic nose for the quality control of red meat. Electronic nose and bacteriological measurements are performed to analyse samples of beef and sheep meat stored at 4°C for up to 15 days. Principal component analysis (PCA) and support vector machine (SVM) based classification techniques are used to investigate the performance of the electronic n...

The effects of ultraviolet (UV) radiation were investigated with regards to the microbial growth inhibitory effect on the shelf life of Korean native cattle (Hanwoo) beef prior to refrigerated storage. The Hanwoo samples were exposed to UV radiation (4.5 mW/cm(2)) for 0, 5, 10, 15, and 20 min. The UV-irradiated beef that was exposed for 20 min showed significantly reduced mesophilic and psychro...

In order to evaluate present and future retail packaging systems, it is necessary to review past fresh red meat (FRM) packaging systems. Prior to 1967, whole beef carcass shipments were traditionally made to retail outlets where carcasses were fabricated into retail items by butchers in individual stores. The "boxed beef" concept was introduced in 1967, dramatically changing beef processing, di...

The effects of storage methods on the shelf-life of dried beef product (Kilishi) were studied under ambient conditions for a period of forty-two days to compare traditional production and packaging system with a potassium sorbate (anti-fungal agent) treatment and modern packaging system. Changes in proximate composition and microbial counts for the control and treated samples were significant. ...

Research was conducted to determine the effect of feeding de-oiled wet distillers grains plus solubles (WDGS) on beef fatty acid profile, retail shelf life and development of oxidation products during retail display (RD). A total of 336 crossbred yearling steers (initial BW = 351.08 ± 19.05 kg) were fed 1 of 7 dietary treatments: an all corn control (1:1 blend of dry rolled and high moisture co...

Tomato is one of the sensitive fruits to mechanical impacts and physical tensions. The mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 J by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety Shiva F1, includingripening factor...

this study evaluated the antimicrobial activities of two lactic acid bacteria, lactococcus lactis subsp. lactis i23 and lactococcus lactis subsp. lactis e91, against brochothrix thermosphacta in pork meat during storage at ambient temperature (30°c) for 168 h. the lab strains and the spoilage organism were inoculated on fresh pork samples at 1×106 cfug-1. results showed about 3 log reduction in...
