Proteolysis of High Quality Raw Milk During Storage at Various Temperatures

Effect of prolonged storage on microbiological quality of raw milk

Milk in its natural state is a highly perishable material because it is susceptible to rapid spoilage by the action of naturally occurring enzymes and contaminating microbes. Good hygiene practice from the farm to dairy, effective refrigeration regimes, reduction of storage times and technologies for reduction of spoilage and pathogenic microorganisms are basic measures needed to be accomplishe...

BACKGROUND: Microbiological and chemical qualities ofmilk are among the most important issues in public health.OBJECTIVES:Although there are a few published studies whichhave been conducted in south east of Iran this study wasperformed to investigate quality of raw milk delivered to a dairyindustry company Kerman Province. METHODS:Atotal of 109raw milk samples were collected at the time of deli...

Creatine kinase in serum: 5. Effect of thiols on isoenzyme activity during storage at various temperatures.

We studied changes in the activity of human creatine kinase isoenzymes (native MM in serum, MM, MB, and BB preparations in serum matrix) on storage in the presence of 0, 10, 20, and 50 mmol of N-acetyl cysteine, 2-mercaptoethanol, and 1-thioglycerol per liter of serum at 37, 30, 25, 4, and -20 degrees C. We also assessed the stability of the thiols under the same conditions. We generally confir...

Aversive quality of low velocity winds at various ambient temperatures.

Calculation of MnO Activity in Aluminate Slags at Various Temperatures

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...
