A rapid method for the estimation of the microbiological quality of refrigerated raw milk was developed based on the aminopeptidase activity of Gram-negative psychrotrophic bacteria, the dominant microbial population in refrigerated foods. Two versions of the test for measuring the aminopeptidase activity are reported (direct and indirect). A good correlation (r=0.93–0.95) between bacterial cou...

Ostrich meat samples were irradiated with 0.0, 1.0 and 3.0 kGy of gamma rays, packaged under vacuum and held refrigerated for 21 days. Lipid oxidation, shear force, colour and sensory quality were determined on day 0, 7, 14 and 21. Irradiated meat showed higher values (P<0.05) for a* (redness) than the non-irradiated samples as from day 21 under refrigeration. Irradiation increased (P<0.05) the...

Epoxy nanocomposites of different content of carbon nanofibers upto 1 wt% have been fabricated under room temperature and refrigerated curing conditions. The composites were studied in terms of mechanical and electrical properties. Flexural modulus and hardness were found to increase significantly in refrigerated samples due to prevention of aggregates of nanofibers during cure condition. Incre...

In the present study the effects on shelf life and sensory acceptance of gamma-irradiated refrigerated poultry breast fillets subjected to modified atmosphere packaging (80% CO2/20% N2 or vacuum) were investigated. After irradiation with 2 kGy, sensory acceptance tests and monitoring of bacterial growth were performed in order to determine the sanitary quality of the samples. It has been found ...

Toxoplasma gondii oocysts are excreted nonsporulated in the feces of the cats into the environment. These oocysts must undergo sporulation to become infectious. Little is known about the factors that influence sporulation of T. gondii oocysts. The present study examined the survival of nonsporulated oocysts under refrigerated conditions over 11-week observation period. Microscopic examination o...

The intent of this paper is to initiate a discussion within the community interested in commercial refrigerators, on the possible use of LED lighting in commercial refrigerated and freezer display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. LED is a solid-state light source tha...

The rapid development of high brightness light emitting diodes (LEDs) has triggered many applications, especially in the area of display lighting. This paper focuses on the application of white LEDs in refrigerated display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. A laborator...

The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12C for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for ...

Foodstuff has to be transported from where it is produced or packaged the market. It important control temperature and humidity of delivered food minimize waste ensure customer satisfaction. At same time, unfortunately, transport sector among polluting sectors. Therefore, innovative solutions have been proposed such as adoption Latent Thermal Energy Storage (LTES) systems based on Phase Change ...
