Volatile Indicators of Deterioration in Liquid Egg Products

ANNEX G Pasteurization of Liquid Egg Products and Shell Eggs

Bioassay for nisin in milk, processed cheese, salad dressings, canned tomatoes, and liquid egg products.

A sensitive nisin quantification bioassay was constructed, based on Lactococcus lactis chromosomally encoding the nisin regulatory proteins NisK and NisR and a plasmid with a green fluorescent protein (GFP) variant gfp(uv) gene under the control of the nisin-inducible nisA promoter. This strain, LAC275, was capable of transducing the signal from extracellular nisin into measurable GFPuv fluores...

Ohmic processing of liquid whole egg, white egg and yolk

The Ohmic heating rate of a food is highly influenced by its electrical conductivity. In this study, electrical conductivities, colour changes and system performance of liquid whole egg, white egg and yolk were determined on a laboratory scale static Ohmic heater by applying 30 V/cm voltage gradient. The samples were heated from room temperature through to pasteurization temperature (19 – 60°C)...

Thermodynamic analysis of volatile organometallic fission products

The ability to perform rapid separations in a post nuclear weapon detonation scenario is an important aspect of national security. In the past, separations of fission products have been performed using solvent extraction, precipitation, etc. The focus of this work is to explore the feasibility of using thermochromatography, a technique largely employed in superheavy element chemistry, to expedi...

Evaluation of Water Use Productivity Indicators in the Main Agricultural Products of Iran

Although the agricultural sector consumes more than 90% of the extracted water, its efficiency is lower than other sectors. Also, according to the population growth and critical role of food security, and the necessity to supply water to other sectors, an increasing pressure to save water, optimized consumption and increasing water use productivity in agriculture will occur in the future. Nowad...
