Staling in Two Canned Lager Beers Stored at Different Temperatures - Sensory Analyses and Consumer Ranking

Benzodiazepine stability in postmortem samples stored at different temperatures.

Benzodiazepine (lorazepam, estazolam, chlordiazepoxide, and ketazolam) stability was studied in postmortem blood, bile, and vitreous humor stored at different temperatures over six months. The influence of NaF, in blood and bile samples, was also investigated. A solid-phase extraction technique was used on all the studied samples, and benzodiazepine quantification was performed by high-performa...

Modeling the Survival of Salmonella in Soy Sauce-Based Products Stored at Two Different Temperatures

Occurrence of polyfunctional thiols in fresh lager beers.

Polyfunctional thiols are known to have a strong impact on the overall aroma of many fermented foods. Surprisingly, very little data is available on their occurrence in beer. A specific extraction with p-hydroxymercuribenzoic acid was performed on four different fresh light-protected lager beers. gas chromatography-olfactometry, gas chromatography-mass spectrometry, and gas chromatography-pulse...

Some Chemical Changes Exhibited in Sterile and in Contaminated Haddock Muscle Stored at Different Temperatures.

The bio-chemical changes which occur in fish tissues are due to two factors, autolysis and bacterial action. As early as 1903, Muller reported that changes due to autolysis took place when sterile fish tissues were incubated. More recently attention has been focussed on the relative importance of these two causes of bio-chemical change. Reed, Rice and Sinclair (1929) presented evidence that aut...

Comparison of viability and heat resistance of Clostridium sporogenes stored at different temperatures.

The objective of this study was to determine the influence of storage temperature on the viability and heat resistance of Clostridium sporogenes spores. Spore suspension containing both spores and vegetative cells was divided into 3 groups to be stored at different temperatures of -20 (freezing), 4 (refrigerating), and 25 degrees C (ambient temperature). Samples stored for different times withi...
