Ochratoxin A (OTA) is one of the main mycotoxins that can be found in food. The use of gamma radiation is a technique for preserving food that may exert some effects on mycotoxins. OTA was irradiated in its dry form, in aqueous and in methanolic solutions, and in wheat flour, grape juice and wine. Additionally, the toxicity of OTA irradiated in water was tested. In aqueous solutions, more than ...

Electron-beam irradiation facilities are commercially utilized for food irradiation. This study investigates whether dosimeters used to detect gamma-rays can also be used to accurately detect electron-beam irradiation. The irradiation souses for gamma-ray at the Takasaki Institute were used throughout this study. Four kinds of dosimeters, RadiaChromic (RC), GammaChromic (GC), Amber3042 (AM), Ra...

Many countries, in order to authorise the use of food irradiation, claim the availability of methods to detect the occurred treatment in addition to the respect of safe use of this technology. Among physical methods, the electron spin resonance (ESR) measuring the number of free radicals that are formed during irradiation can be applied only to those foods with cellulose, a crystalline or bone ...

AIMS To compare three bacterial DNA extraction procedures on cold-smoked salmon (CSS) and assess the impact on their efficiency of two physical treatments of the food matrix, ionizing irradiation and freezing. METHODS AND RESULTS As molecular methods for bacterial detection have become an important analytical tool, we compared bacterial DNA extraction procedures on CSS. Working with frozen an...

The sanitary and hygienic safety of modern packaging is determined by the layer material in direct contact with food product. This most cases a synthetic polymer polyolefin class — low density polyethylene. used as stand-alone multilayer combined materials. During thermal photooxidation, compounds can form it that negatively affect package, which migrate into Food technologies use methods disin...

Irradiation is the process of exposing food to some dose radiation extend shelf life food. The present study was done on shelf-life extension wheat four by gamma radiation. Gamma rays are used for processing, whose light source obtained from a 60 Co radionuclide source. properties have adverse effects nutritional whole flour with less than 5 kGy. physiochemical and has been analysed. moisture c...

background:  hydrogen has been demonstrated can selectively reduce the hydroxyl, which is the main cause of ionizing radiation-induced damage. amifostine (am) is the only radioprotective drug approved by the u.s. food and drug administration for use in radiotherapy. the purpose of the present study was to investigate the combined radio-protective effect of hydrogen rich water (hrw) and am. mate...
