Химики из СПбГУ разработали метод определения опасных для человека антибиотиков в продуктах
Учёные из Санкт-Петербургского государственного университета (СПбГУ) создали автоматизированный метод определения опасных для человека антибиотиков фторхинолонов в продуктах питания и жидкостях.
Специалисты СПбГУ создали алгоритм выведения антибиотиков из исследуемого объекта методом экстракции. Процесс происходит под влиянием безопасных и высокоэффективных растворителей нового поколения. После экстракции полученную субстанцию анализируют при помощи жидкостной хроматографии. В результате исследования определяется наличие фторхинолонов и их остаточных следов в продуктах. Проверка метода была успешно осуществлена на различных объектах: сточных водах, молоке и креветках.
Отмечается, что разработанный способ подходит для автоматизированной проверки. Это существенно сократит трудозатраты и исключит человеческий фактор при проведении анализов. Метод считается перспективным для применения в сфере пищевой промышленности.
Напомним, что фторхинолоны являются самым распространенным типом синтетических антибиотиков. Они широко применяются в сельском хозяйстве, фармакологии, пищевой промышленности. Ранее фторхинолоны считались условно безопасными для человека, однако большое количество выявленных побочных действий вызвало сомнения на этот счёт у учёных. Сейчас специалисты призывают ужесточить контроль за применением этих веществ во всех сферах.
