OBJECTIVE The present study investigates the activity changes of sphingomyelinase (SMase), ceramidase and caspase-3 in colonic mucosa of rats induced by high fat and red meat diets. METHOD For a period of 3 weeks, rats were fed protein without fat (control), high fat only, high fat with beef, and high fat with fiber (cellulose) diets. The fat content (22.4%) was constant in the three high fat...

Some groups of male Sprague-Dawley rats were fed a diet containing either 28% beef fat and 2% corn oil or 30% corn oil (high fat), and others were fed either 13% beef fat and 2% corn oil or 15% corn oil (moderate fat), for varying periods of time, with or without exposure to aflatoxin B, (AFBi). Assays for hepatic microsomal oxidases [p-nitroanisole demethylase and benzo(a)pyrene hydroxylase] w...

The objective of this study was to evaluate the chemical, physical and sensory characteristics of lowfat beef patties formulated by replacing different levels (25, 50, 75 and 100%) of fat with hydrated potato flakes. Uncooked and cooked beef patties formulated with potato flakes had higher (p#0.05) moisture, carbohydrate and ash content and lower (p#0.05) fat contents than that of the control. ...

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 ...

The development of a novel rapid dual energy X-ray absorptiometry (DEXA) system provides the opportunity to improve measurement beef carcase composition. A prototype DEXA was built in shipping container scan 51 carcases selected for wide range weight and fatness. One side each spray chilled other conventionally overnight before being quartered scanning then cut into 16 pieces CT determine Spray...

Meat productions from sixteen local Portuguese cattle breeds represent high economic and cultural value for local populations. Among these, Minhota is one of the most important on meat aptitude located on the northwest of the country. This breed is used for high-quality meat. This study describes the influence of slaughter age, corresponding veal (6 months) and beef (9 months) and sex, reared i...

The proximate composition, physical traits and sensory properties of beef and chicken patties incorporated with various level of dried cornsilk (Maydis stigma) were studied. The beef and chicken patties were formulated with either 2%, 4% or 6% of cornsilk. Both cooked beef and chicken patties incorporated with 6% cornsilk recorded the highest protein concentration at 23.3% and 28.42%, respectiv...

OBJECTIVE The objective of this research was to evaluate the physico-chemical, microbiological and sensorial qualities of restructured steaks processed from beef trimmings (grade I and II) and frozen beef (fresh beef as control and frozen beef). METHODS Beef trimmings from commercial butcher were collected, designated into 4 treatments differing in beef trimmings grade and freezing, processed...

The potential of the composition of the forerib measured by X-ray computed tomography (CT) as a predictor of carcass composition was evaluated using data recorded on 30 Aberdeen Angus and 43 Limousin crossbred heifers and steers. The left sides of the carcasses were split into 20 cuts, which were CT scanned and fully dissected into fat, muscle and bone. Carcass and forerib tissue weights were a...

A market basket survey for beef retail cut composition at the retail level (four stores each from two chains in each city) was conducted in 11 US cities from January to March 2006. Beef cuts (n=17,495) were measured for external fat thickness with cuts from the chuck (0.05cm), round (0.05cm), and miscellaneous (0.04cm) having less (P<0.05) fat than cuts from the loin (0.11cm) and rib (0.11cm). ...
