The antimicrobial activity of essential oils of oregano, thyme, basil, marjoram, lemongrass, ginger, and clove was investigated in vitro by agar dilution method and minimal inhibitory concentration (MIC) determination against Gram-positive (Staphylococcus aureus and Listeria monocytogenes) and Gram-negative strains (Escherichia coli and Salmonella Enteritidis). MIC(90%) values were tested again...

The polymerase chain reaction (PCR) was used as a tool for the detection of enterotoxigenic Escherichia coli in minced meat. With two synthetic 29-mer oligonucleotides, a 195-bp fragment from the E. coli heat-labile enterotoxin (LT) gene could be amplified specifically. When 6 CFU was added to the reaction mixture as a template, the PCR yielded sufficient amplified product for visualization on ...

A simulation method for approximating spectral signatures of minced meat samples was developed depending on concentrations and optical properties of the major chemical constituents. Minced beef samples of different compositions scanned on a near-infrared spectroscopy and on a hyperspectral imaging system were examined. Chemical composition determined heuristically and optical properties collect...

Because of their inhibitory effects, selected probiotic Lactobacilli may be used as antimicrobial against some hazardous microorganisms responsible for spoilage of fresh minced beef (cattle) minced meat and camel minced meat. Lactic acid bacteria were isolated from camel meat. These included 10 isolates; 1 Lactobacillus fermenti, 4 Lactobacillus plantarum, 4 Lactobacillus pulgaricus, 3 Lactobac...

1. Minced muscle and liver of normal rats produce glycogen from glucose-l-phosphate in vitro. 2. If, after a starvation period, the glycogen content falls below 200 mg./100 g., minced liver and muscle do not produce glycogen from glucose-lphosphate. However, if glycogen is added as well, additional glycogen is produced, just as with pure enzyme solutions. 3. In adrenalectomized, adynamic rats t...

An outbreak of diarrhoea occurred at a 647-bedded long-stay hospital from 11 to 14 June 1989. Fifty-eight elderly residents developed symptoms and there were two deaths. The organism was identified as Clostridium perfringens type A, serotype TW23. The source of the outbreak was found to be inadequately reheated minced beef served at lunchtime on 11 June. The reason why only 4 of the possible 16...

This study developed a technique for the preparation of pâté from cachapinta (Pseudoplatystoma sp) waste. For this, frozen minced cachapinta fish was crushed in a mini cutter and homogenized with all other ingredients. The prepared pâté was stored in seamed and thermally treated cans (volume 170 g). Weight proportions of mean moisture, ash, protein, and lipid contents of the minced fish were 75...

A new product of minced fish meat with high pressurization was produced for individuals with difficulties in mastication and swallowing and for elderly people on a dysphagia diet. Minced fish meat was added to distilled water at ratios of 1:0.5, 1:1 and 1:1.5 by mixing with 1.5% NaCl. Half of the samples were modified by heating (H-gels) and half by high pressure at 400 MPa for 20 min (P-gels)....

BACKGROUND Older individuals generally experience a reduced food-chewing efficiency. As a consequence, food texture may represent an important factor that modulates dietary protein digestion and absorption kinetics and the subsequent postprandial protein balance. OBJECTIVE We assessed the effect of meat texture on the dietary protein digestion rate, amino acid availability, and subsequent pos...

An active film composed of chitosan and kombucha tea (KT) was successfully prepared using the solvent casting technique. The effect of incorporation of KT at the levels 1%-3% w/w on the physical and functional properties of chitosan film was investigated. The antimicrobial activity of chitosan/KT film against Escherichia coli and Staphylococcus aureus was evaluated using agar diffusion test, an...
