The Stomacher® was used to prepare samples of skin, liver and breast meat for PCR study. The present study provides data on contamination level with Campylobacter in poultry and poultry products after air chilling. Continue reading
The inoculated meat was blended with a Stomacher 400 for 5 min to ensure even distribution of sodium nitrite and the organisms in the meat samples.
The study shows that the kinetic and growth parameters obtained from this study can be used in evaluating growth of C. perfringens from spore populations during dynamically changing temperature conditions such as those encountered in meat processing. Further, this model can be successfully used to design microbiologically “safe” cooling regimes for cured pork hams and similar products.
The test system was ground pork that was mixed with a diluent, homogenized with a stomacher 400. The study shows that Aromatic compound Benzaldehyde was the aromatic compound that was detectable by the electronic nose.
Meat samples (10 g) were blended in a Stomacher® 400 for 90 s in 90 ml of 0.1% (w/v) peptone water.
The high microbial loads found in this study suggest an improvement of the microbiological quality of retail ostrich meat is convenient.
Sterile meat was thawed rapidly (in about 5 min) by submerging the package in a
50°C water bath, inoculated with enough cells ( 10 ml/100g of meat) for a final
population of ca. 109 stationary- phase cells per g, and stomached for 90 s in
sterile no.400 polyethylene stomacher bags using a Stomacher® 400.
To enumerate L. monocytogenes, 0.1 M phosphate buffer was added to each
stomacher bag (5-g beef slice in 45 ml of phosphate buffer), and the contents were mixed in a Stomacher 400 for 2 minutes.
The Stomacher® 400 was used to blend reindeer meat for two minutes.
The study found that at slaughter, there was no difference in ASAT activity, urea and Cortisol concentrations between the two transported groups. However, the plasma ASAT activity and urea concentrations at slaughter were significantly lower in the non-transported group. In both transport groups, the plasma Cortisol concentrations increased during loading onto and unloading from the lorry. Abomasal lesions were observed in all treatment groups. It was concluded that reindeer showed an acute stress response to manual handling and transport.
The Stomacher® 400 is used as a key piece of equipment in the USDA methodology for meat species identification.
The 25-g aliquots were placed in Stomacher® 400 filter bags containing 225 ml of buffered peptone water (HiMedia Laboratories, Mumbai, India). The samples and diluent were mixed in Stomacher® 400 for 60 seconds.
The study found that there was no difference for the recovery of C. jejuni from fresh, refrigerated or frozen samples after selective enrichment, showing that this microorganism can survive under the tested storage conditions.
The Stomacher® 400 was used to blend beef pieces for one minute as part of the study. the study found that if chilled carcasses were subjected to low-dose E beam irradiation, the aroma and flavour of the ground beef would not be impacted. The data presented indicates that low-dose, low-penetration, E beam irradiation has potential use as an antimicrobial intervention on beef carcasses during processing and minimally impacts the organoleptic qualities of the treated beef products.
