The influence of pasteurization and sodium chloride, sodium ascorbate, polyphosphates and sodium nitrite coupled with pasteurization on nitrosamine contents in pork was studied. Nitrosamines: dimethylonitrosamine (DMNA) and diethylonitrosamine (DENA) were extracted from raw material, distilled, condensed in an evaporator under lowered pressure and analyzed chromatographically. An inhibitory eff...

A method is introduced, which permits the determination of melibiase (a-galactosidase) in non-pasteurized Lager beers. Typically, melibiase activities of about 40 Units per litre are encountered for non-pasteurized Danish Lagers (Pilsner). The properties of melibiase in Lager beer have been examined. The rate constants for inactivation of melibiase in Lager beer of pH 4 have been determined at ...

Abstract The soymilk is a ready-to-eat, nutritious and naturally cholesterol-free product. Several soybean specialty cultivars were developed in Brazil order to increase the human consumption of products. aim this work was evaluate nutritional composition consumer acceptance from three with special features such as high-protein isoflavone contents, mild flavor lipoxygenase-free compared convent...

In November 1950, a relatively modern factory, called Alpha, was established in Javadiyeh district of Tehran. It was the first factory of milk pasteurization in Iran, which started by pasteurizing five tons of milk per day and manufacturing dairy products. The factory was under official health supervision of Pasteur Institute of Iran and had a significant contribution to the improvement of the ...

The electrical and structural properties of Hf/Al/Ni/Au (20/100/25/50 nm) ohmic contact to n-GaN are reported in this study. Specific contact resistivities of Hf/Al/Ni/Au based contacts have been investigated as a function of annealing temperature and achieve the lowest value of 1.09×10 Ω·cm after annealing at 650 C in vacuum. A detailed mechanism of ohmic contact formation is discussed. By usi...

Drs Giles and Mijch have provided a timely case of an HIVinfected woman elected to exclusively breastfeed applying milk pasteurization techniques [1]. This is the first report of such a case in a developed country. We would appreciate the opportunity to discuss the effect of pasteurization in this paper. HIV RNA was detected at <250 copies/mL in the first paired specimens of breast milk, both p...

This paper reports on the design and fabrication of a High Temperature Short Time (HTST) camel milk pasteurization pilot plant. The objective of this project is to design and fabricate a low cost and practical camel milk pasteurization pilot plant which will work well in an agricultural setting in the Kingdom of Saudi Arabia. Fresh camel milk is a much sought after delicacies in the Arab world,...

The synergistic effects of high hydrostatic pressure (HHP), mild heating, and amino acids on the germination of Clostridium sporogenes spores were examined by determining the number of surviving spores that returned to vegetative growth after pasteurization following these treatments. Pressurization at 200 MPa at a temperature higher than 40°C and treatment with some of the 19 l-amino acids at ...

Legionella is an opportunistic waterborne pathogen of increasing public health significance. Pasteurization, otherwise known as super-heat and flush (increasing water temperature to above 70°C and flushing all outlets), has been identified as an important mechanism for the disinfection of Legionella in manufactured water systems. However, several studies have reported that this procedure was in...
