A cell-free translation assay was applied for the quick detection of ricin in food samples. Three economically important foods-ground beef, low-fat milk, and liquid chicken egg--were tested. The results indicated that ground beef had very little matrix effect on the assay, whereas low-fat milk and liquid chicken egg showed clear interference on the protein translation. A simple dilution in phos...

Beef flavor has been identified as a driver of consumer acceptability; however, little is known about variability in major United States retail beef cuts. Four cuts (chuck roast; top sirloin steaks; loin and 80/20 ground beef) were obtained from stores (n=30 per cut city) Miami, Los Angeles, Portland, New York, Denver during 2-mo period 2018. Production systems or package claims documented. An ...

A U.S. consumer (n = 642) study (Baltimore, MD; Phoenix, AZ; and Lubbock, TX) was conducted to compare consumer sensory scores of U.S. beef (83 USDA Choice [Choice] and 96 USDA Select [Select]) and Canadian beef (77 AAA and 82 AA) strip loins. Strip loins (n = 338) were obtained from beef processors in Canada and the United States and were wet aged until 21 d postmortem at 2°C. Marbling scores ...

The purpose of this investigation was to determine whether diets high in animal or vegetable fat affected mammary tumorigenesis when fed to rats only prior to and during the initiation phase of carcinogenesis. Weanling 21-day-old female Sprague-Dawley rats were divided into different dietary treatment groups and were allowed to feed and libitum on one of the following diets: 5% (normal fat) cor...

In this paper we investigate the feasibility of genetic programming for combining features extracted from meat images to predict fat content. Images of beef meat were acquired and analyzed. Feature sets including fat percentage, fat fleck size distribution and homogeneity measurements were extracted from these images. Using genetic programming we built individual programs which give a predictio...

Objective: By investigating the effects of feeding Enterococcus faecalis FK-23 preparation to Japanese Black cattle in the late fattening period, this paper discusses the increased value of beef and the feasibility. Method: 10 beef cattle were grouped into the Test Group and the Control Group, 5 beef cattle in the Test Group were fed E. faecalis FK-23 preparation at 8.0 g per day per head. The ...
