To investigate how B. anthracis Sterne spores survive in milk under heat (80 degrees C, 10 min), pasteurization (72 degrees C, 15 s), microfiltration, and pasteurization and microfiltration, the expression levels of genes related to sporulation and germination were tested using real-time PCR assays. Twenty-seven sporulation- and germination-related genes were selected for the target genes. Our ...

The effect of cream pasteurization on the composition and microstructure of buttermilk after pasteurization, evaporation and spray­ drying was studied. The composition of milk fat globule membrane (MFGM) isolated from buttermilk samples was also characterized. Pasteurization of cream resulted in higher lipid recovery in the buttermilk. Spray-drying of buttermilk had a significant effect on phos...

For many years, sodium caprylate has been used as a suitable stabilizer to retain biological activity of pharmaceutical proteins such as human albumin solutions during pasteurization. A simple method of turbidity assay was applied for evaluation of sodium caprylate as a stabilizer to protect biological activity of infusible platelet membrane product during pasteurization at 60°C for 20 h. Conce...

Novel, effective methods to control and prevent spoilage and contamination by pathogenic microorganisms in meat and meat products are in constant demand. Non-thermal pasteurization is an ideal method for the preservation of meat and meat products because it does not use heat during the pasteurization process. Atmospheric pressure cold plasma (APCP) is a new technology for the non-thermal pasteu...

In the United States, concerns over the transmission of infectious diseases have led to donor human milk generally being subjected to pasteurization prior to distribution and use. The standard method used by North American milk banks is Holder pasteurization (63 degrees C for 30 minutes). The authors undertook an experiment to validate the effects of a high-temperature short-time (HTST) pasteur...

The economics of cold food pasteurization are governed by a number of factors, including: the type of ionizing radiation source (X-Ray, or Gamma), cost and power of the source, pasteurization dose, location of the pasteurization facility, facility capacity factor, and the annualized costs. Using a costing procedure developed by Morrison [1], calculations for typical sources, locations, etc., ha...

In This paper describes the design and implementation of Microcontroller based High Voltage pulse electric field generator for Liquid food pasteurization. It generates a high voltage (15 kV) approximately in the frequency range from 250 Hz to 30 kHz. This high voltage applied for food pasteurization, which is placed between two electrodes.

Globally, 230,662 metric tons of liquid egg products are marketed each year. The presence of highly pathogenic avian influenza (HPAI) or Newcastle disease in an exporting country can legitimately inhibit trade in eggs and processed egg products; development and validation of pasteurization parameters are essential for safe trade to continue. The HPAI virus (HPAIV) A/chicken/Pennsylvania/1370/19...

BACKGROUND & OBJECTIVES In current era of limb-salvage therapy, pasteurization of bone sarcomas is receiving growing attention as a potential extracorporeal treatment and cost-effective alternative to allografts and radiation before surgical reimplantation. Detailed in vitro and in vivo pre-clinical study to evaluate efficacy of pasteurization to eradicate malignant cells has not been reported ...

We evaluated the efficacy of a commercial washer-pasteurizer. Carriers were inoculated with 10(4) to 10(6) test organisms and pasteurized at 170 degrees F for 30 minutes. Pasteurization eliminated all test organisms with the exception of Bacillus subtilis spores. Pasteurization appears efficacious for the disinfection of respiratory-care equipment and could result in a cost savings of approxima...
