Оптические фотолюминесцентные свойства яиц сельскохозяйственной птицы могут служить индикаторами их качества как для процессов инкубации, так и для процессов пищевых технологий. На начальном этапе представляется важным провести оценку спектральных характеристик возбуждения и люминесценции, а также параметров столовых и инкубационных яиц различного качества и с различным цветом скорлупы.</p></sec><sec><title>Методы</title><p>Методы. Для исследований были использованы куриные яйца кроссов китайская шелковая и Хайсекс браун, а также образцы утиных, гусиных и перепелиных яиц. Измерения проводились на дифракционном спектрофлуориметре «Флюорат-02-Панорама» с встроенным программным обеспечением Panorama Pro. По полученным спектральным характеристикам были рассчитаны энергетические (интегральная поглощательная способность и поток люминесценции, энергия спектра) и статистические (математическое ожидание, дисперсия, асимметрия, эксцесс) параметры, а также стоксов сдвиг.</p></sec><sec><title>Результаты</title><p>Результаты. Фотолюминесцентные свойства яиц сельскохозяйственной птицы проявляются в ультрафиолетовой области спектра. Качественно спектры различных видов домашних птиц схожи с незначительным различием стоксова сдвига. Для оплодотворенных куриных яиц поток фотолюминесценции в 2,7 раза больше, чем у неоплодотворенных, при этом разброс значений для неоплодотворенных яиц в 5,6 раза меньше. Такие параметры спектров, как асимметрия и эксцесс, существенно различаются для люминесценции темно- и светлоскорлупных куриных яиц. Для столовых яиц интегральные энергетические параметры в 2,8–3,1 раза больше, чем у инкубационных.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Optical photoluminescent properties of poultry eggs can serve as indicators of their quality both for incubation processes and for food technology processes. At the initial stage, it is important to evaluate the spectral characteristics of excitation and luminescence, as well as the parameters of table and incubation eggs of different quality and with different shell color.</p></sec><sec><title>Methods</title><p>Methods. Chicken eggs of Chinese silk and Hysex brown crosses, as well as samples of duck, goose and quail eggs were used for research. The measurements were carried out on a diffraction spectrofluorimeter “Fluorat02-Panorama” with built-in software “Panorama Pro”. The obtained spectral characteristics were used to calculate the energy (integral absorption capacity and luminescence flux, spectrum energy) and statistical parameters (expectation, variance, asymmetry, kurtosis), as well as the Stokes shift.</p></sec><sec><title>Results</title><p>Results. Photoluminescent properties of poultry eggs are manifested in the ultraviolet region of the spectrum. Qualitatively, the spectra of different species of domestic birds are similar with a slight difference in the Stokes shift. For fertilized chicken eggs, the photoluminescence flux is 2.7 times greater than that of unfertilized eggs, while the spread of values for unfertilized eggs is 5.6 times less. Spectrum parameters such as asymmetry and kurtosis differ significantly for the luminescence of dark and light-shell chicken eggs. For table eggs, the integral energy parameters are 2.8–3.1 times greater than those of incubation eggs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>столовые и инкубационные яйца</kwd><kwd>спектр возбуждения</kwd><kwd>спектр фотолюминесценции</kwd><kwd>стоксов сдвиг</kwd><kwd>оптические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>table and incubation eggs</kwd><kwd>excitation spectrum</kwd><kwd>photoluminescence spectrum</kwd><kwd>Stokes shift</kwd><kwd>optical properties</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Якименко И., Бесулин В., Бессарабов Б.
