Sci., 19: 293-297 The objective of the present study was to prove the radiation treatment of a set of lyophilized forest fruits (blackberry, blueberry, aronia, strawberry and black elder), irradiated with doses of 2 and 4 kGy b...
متن کاملNatural and Gamma Induced Free Radicals in Dried Fruits. an Epr Study
ALEKSIEVA, K., I. NACHEVA, K. DIMOV and Tsv. TSVETKOV, 2016. Natural and gamma induced free radicals in dried fruits. An EPR study. Bulg. J. Agric. Sci., 22: 1010–1013 The aim of the present study is to prove radiation processing in air dehydrated dates, prunes and fi gs, as well as to recommend which part of the fruit to sample. The detection method is Electron Paramagnetic Resonance (EPR) spe...
متن کاملEPR study of gamma – irradiated cereal foods
The results from the EPR studies on wheat and oat bran, rolled oats, buckwheat and different kind of rice – white, brown and parboiled rice before and after gamma-irradiation are reported. Before irradiation all samples exhibit one weak singlet EPR line characterized with common g-factor of 2.00480.0005 and six lines due to Mn naturally available in the plants. Only parboiled rice did not show...
متن کاملStudy on radiation-induced radicals giving rise to stable EPR signal suitable for the detection of irradiation in L-sorbose-containing fruits
Ionizing radiation is useful for the conservation and disinfestation of fresh and dried fruits. The treatment of fruits with gamma-rays or beams of accelerated electrons has been carefully tested and was recommended by FAO/WHO Codex Alimentarius Commission for the common use as an effective and safe preservation method [1]. It was found earlier that the ionizing radiation produces stable EPR si...
متن کاملBroadband Transmission EPR Spectroscopy
EPR spectroscopy employs a resonator operating at a single microwave frequency and phase-sensitive detection using modulation of the magnetic field. The X-band spectrometer is the general standard with a frequency in the 9-10 GHz range. Most (bio)molecular EPR spectra are determined by a combination of the frequency-dependent electronic Zeeman interaction and a number of frequency-independent i...
