Radio frequency (RF) tempering is considered as a fast and volumetric heating technology has been proved to be effective in meat tempering. However, the thermal runaway problem usually causes uneven at sample edges. In this study, newstrategy whereby frozen was surrounded by selected medium developed evaluated order improve uniformity. The RF uniformity improvement effects of crushed ice, ethan...

D ry aging beef to enhance its flavor and tenderness is used by a very small number of meat purveyors for upscale hotels and restaurants and by an even smaller number of retailers for the gourmet market. Dry aging is a process whereby beef carcasses, primals, and/or subprimals are stored – without protective packaging – at refrigeration temperatures for one to five weeks to allow the natural en...

In PNAS, Eshel et al. (1) present a novel methodology for calculating a suite of ecological impacts from livestock and poultry production in the United States. The authors acknowledge two complementary and valuable approaches in ecological accounting: bottom up and top down. Top-down analyses, however, are only valuable insofar as they adequately represent the structure of the study system. By ...

Irradiation significantly decreased the redness of ground beef (P < 0.05), and the visible color of beef changed from a bright red to a green/brown, depending on the age of meat. Addition of ascorbic acid (0.1%, wt/ wt) in ground beef prior to irradiation prevented color changes in irradiated beef, and the effect of ascorbic acid became greater as the age of meat or storage time after irradiati...

specific variations in sarcoplasmic proteome influence beef color. Post-mortem aging is a common practice employed by beef industry for improving beef tenderness and palatability. However, the color attributes and sarcoplasmic proteome of beef muscles undergo changes during aging. The objective of this study was to examine the changes in the sarcoplasmic proteome profile of three differentially...

The discovery of bovine spongiform encephalopathy (BSE), commonly known as ‘mad cow disease’, in Japan caused anxiety about consuming beef and beef products. As a result, there was a sudden fall in sales of beef that hurt the Japanese beef industry as well as major beef exporters to Japan. We analyse factors that affect Japanese consumers’ willingness to pay (WTP) price premiums for BSE-tested ...

The study investigated the dietary impact of 18:3n-3 vs. 18:2n-6 on fatty acid- and micronutrient concentration of beef muscle and the extent of diet- and processing-induced changes of lipid- and micronutrient concentrations of beef products made thereof (German Corned beef (GCB), tea sausage spread (TSS), scalded sausage (SS)). Beef and beef products were obtained from German Holstein bulls wh...

This study investigated the effect of injecting pineapple concentrate and honey into low marbled beef in order to enhance its sensory qualities, particularly tenderness and flavor, without compromising its fresh appearance. Beef loin was injected with a solution of 6.0% pineapple concentrate, 2.5% honey, 0.5% monosodium L-glutamate, 0.5% phosphate, and 0.3% salt (w/w) to 120% (w/w) of initial m...

ABSTRACT: Large quantities of beef and mutton tallow are available in Iran every year. If these products are processed and formulated properly and scientifically, the need to import oils and fats in a substantial quantities might be reduced. The aim of this study is to fractionate beef tallow into different fractions and carry out physical and chemical tests on each isolated fraction. Beef fat ...
