چکیده

A selection of second cross lambs (18 to 24 kg, fat score 2 to 3), processed at a country abattoir, were subjected to either high voltage (HV) or low voltage (LV) electrical stimulation (ES) within 30 minutes of slaughter. Warner Bratzler (WB) shear force measurements were made on loin and leg muscles to investigate the effects of electrical stimulation on tenderness. Ultimate pH, meat colour and sensory appraisal tests were also conducted to assess meat quality characteristics. An untrained (consumer) taste panel found the stimulated meat samples to be significantly (P<0.05) more tender with better eating quality characteristics then the unstimulated samples. WB shear force testing showed loins from both treatment groups to be significantly more tender than leg muscles.

Effects of Electrical Stimulation on Meat Quality of Lamb and Goat Meat

Effect of various voltage of electrical stimulation (ES) on meat quality of lamb and goat was investigated by using a total of 36 animals at 3-5 years old. Constant 50 Hz frequency and 50, 100, and 250 V, 90 sec of ES were administered to 1/2 carcasses and were examined according their textural, physicochemical, and sensorial characteristics. ES decreased the pH values of lamb and goat meat, an...

Effect of Calcium Alginate Edible Coatings on Microbial and Chemical Properties of Lamb Meat during Refrigerated Storage

Background: Edible films and coatings have potential benefits for food packaging, particularly meat products. These coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. In this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of&nbsp; 5 days was...

Evaluation the Impact of Carcass Weight, Age at Slaughter, and Sex on the Chemical Composition of Lamb Meat: The Case of the Boutsiko Sheep Breed

The effect of carcass weight, age at slaughter and sex on some chemical components was evaluated in twenty-two Boutsiko lambs (twelve females and ten males). Chemical composition of meat was expressed as percentage of fat, protein, collagen and moisture content. Measures of the four chemical components were taken by carcass cuts included shoulder, leg, racks, kidney, rear flank, breast ribs and...

Efficacy of Carcass Electrical Stimulation in Meat Quality Enhancement: A Review

The use of electrical stimulation (ES) as a management tool to improve meat quality and efficiency of meat processing is reviewed. The basis of the efficacy of ES is its ability to fast track postmortem glycolysis, which in turn stimulates myriad histological, physical, biochemical, biophysical and physiological changes in the postmortem muscle. Electrical stimulation hastens the onset and reso...

Electrical stimulation and hydration to optimise meat quality

This article discusses research that was conducted to optimise new electrical-stimulation technologies and to elucidate the effects of pre-slaughter dehydration of lambs. A change in lamb processing to a focus on eating quality has increased the uptake of new electrical technologies. Our research was aimed at understanding how carcase response to electrical stimulation is affected by genotype, ...
