The effects of pre-rigor high-pressure treatment of beef semitendinosus
muscle on tenderness, juiciness, and flavor were studied
using both objective and subjective tests. Objective tests included
Warner-Bratzler shear, myofibril protein solubility, total moisture,
water-holding capacity, pH, total nitrogen, and fat content for raw
and cooked samples. Total, evaporation, and drip...
Effects of high temperature aging upon certain characteristics
of bovine l. dorsi muscle were studied. Paired wholesale ribs of
carcasses were obtained subsequent to slaughter. The left rib of
each pair was held at 30°C for 24 hours, then stored at 3°C.
Analogous right ribs were immediately stored at 3°C....
A study was completed to determine the extent of the
protein changes occurring in ground beef stored at
2°C for 10 days.
Sections of semitendinosus muscle were obtained
immediately after the slaughter of three beef animals.
Each section was divided into two equal portions, one of
which was ground and...
Investigations were conducted to determine the effect of prerigor pressurization (15,000 psi, 37°C, 2 min.) of beef muscle on the subsequent retail/case-life characteristics of the treated meat. In addition, the activity of the calcium activated factor (CAF) of prerigor pressurized (PRP) muscle was also investigated. For fresh beef samples, PRP...
This study was designed to investigate the rate of pH decline, changes in protein solubility and in the water-holding capacity (WHC) of beef muscles subjected to pre-rigor electrical stimulation. Samples for the experiment were obtained from animals slaughtered at the Meat Science Laboratory, Oregon State University. Nine good quality steers...
Investigations were conducted to determine whether the low molecular weight nitrogen compounds and the extra protein complex of bovine psoas major muscle were altered during a 12-day aging period.
Electrophoretic studies of soluble proteins either before or after gel filtration on Sephadex G-25 columns indicated that the soluble proteins were...
