Purified epsilon prototoxin of Clostridium perfringens type D was produced, purified, and detoxified by the stoiechiometric method of non-radioactive iodine incorporation. Different degrees of iodination were perfomed and the toxicity of the derivatives were analysed by in vivo studies. Toxicity decreased inversely to the iodine incorporation. Eletrophoretic analysis showed different levels of ...

In this study we compared the effects of duration of cold ischemia (longer and shorter ischemia) on the yield, viability and preservation of the physiological function and insulin secretion of adult human pancreatic islets in short-term (seven days) culture. Based on the tested parameters, we established that there are no major differences between these two test groups and that the storage and ...

Aim: Fresh chicken meat is especially susceptible to surface contamination. The researchers are looking into non-thermal and non-chemical preservation techniques for meat. Therefore, the present study was planned investigate use of UV-C light decontamination raw carcasses at refrigeration temperature (0-4OC).
 Study Design: undertaken in two phases wherein, first phase standardization UV d...

The role of contact with nickel-containing coins has been controversial. The aim of our study was to compare the release of nickel from Euro (1 and 2) coins and from Polish coins (2 PLN and 5 PLN) at 4oC and 32oC in an immersion test using artificial sweat according to the EU reference method. Nickel extract was analyzed at 8 time points starting from 1 h up to 168 h. After 7 days of test durat...

The aim of this work was to monitor the changes both in the composition and in some sensory parameters of Colombian Arabica coffee brews stored at room and refrigeration temperatures, with and without oxygen. Some nonvolatile compounds related to the taste of coffee brews were determined, in an attempt to study possible relationships between chemical and sensory changes. Storage time hardly aff...

‘Qingcui’ plum fruit becomes soft at harvesting. In this study, we assessed the effect of following different treatments on various texture parameters: three concentrations nitrogen (NH4NO3 0%, 0.5% and 1%) forms selenium (selenomethylcysteine [C5H9NO2SSe/SeMeCys], sodium selenate [Na2SeO4] sele-nomethionine [SeMet]). The parameters evaluated were fracture, hardness, cohesiveness, springiness, ...

Potassium is the principal intracellular cation with sodium being the principal extracellular cation. Maintenance of the distribution of potassium and sodium between the intracellular and the extracellular compartments relies on several homeostatic mechanisms. This study analysed the effect of blood storage on the concentrations of potassium and sodium in stored blood and also determine any var...

Recent recurrence of Salmonella contamination of peanut butter has become a serious food safety concern for consumers. A study was conducted to identify storage periods and temperature conditions of peanut butter in domestic kitchens and to determine the effects of those storage periods and conditions on survival of Salmonella and Escherichia coli O157:h7. Surveys assessed consumer storage peri...

The experiment was conducted to find out the effect of salt and storage temperature on the physico-chemical properties of beef nugget. For this purpose nugget samples were divided into two parts; one is called fresh nugget and another is preserved nugget at different temperatures. Then the fresh samples as well as the preserved samples were divided into four subdivisions. Then these are treated...
