Preparation of novel derivatives of pectinic acid for encapsulation of plant oils (Получение новых производных пектиновой кислоты для микрокапсулирования растительных масел)
Аннотация
Микрокапсулы на основе гидразида пектина были исследованы в ходе данной работы. Стабильные микрогели были получены и использованы в качестве эмульгаторов Пикеринга с использованием гексаметиленгуанидин хлорида в концентрации 0.5-1.5 г/л. Размеры частиц микрогеля были измерены с помощью динамического рассеяния света. Система была стабильной при распределении частиц в диапазоне от 100 до 500 нм. Эмульсии вода в масле были получены, при этом толуол был использован в качестве модельного, а соевое масло в качестве целевого вещества. Капсулы были стабилизированы с помощью ионов кальция, а полученные образцы изучены с помощью оптической микроскопии OLYMPUS GX – 71. Это исследование открывает путь к рациональному дизайну микрокапсул на основе природных полисахаридов.
Microcapsules based on pectin hydrazide via Ugi reaction have been investigated. Stable microgel was created as pickering type emulsifiers, under hexamethyleneguanidine chloride at the concentration range of 0.5-1.5g/L. The size of the microgel particles was measured by dynamic light scattering technique (DLS). System was stable with diapason size distribution between 100nm and 500nm. Water/Oil emulsions were created; toluene has been used as model and Soya oil as target compound. Capsules ware stabilized under complexation of Ca2+ ions with pectin polymers. This emulsion was assessed by optical microscopy studies using OLYMPUS GX – 71 microscopes equipped with SIAMS Photolab. The stable microcapsules with average diameter in the range of 10-100 µm have been obtained. This research open the way to rational design of microcapsules basis on natural polysaccharides.
