Документ Effect of treatment modes on quality and antioxidant properties of tomato and beet processing products(2018) Petrova, Zhanna; Pazyuk, Vаdym; Samoilenko, Kateryna; Chepeliuk, OlenaThe research was conducted to substantiate the rational drying conditions of tomato seeds. The ratio and drying conditions of the composition from tomato waste with the addition of red beet were substantiated. The tomato seeds were prepared according to the traditional methodology used in the industry. From red beet and tomato waste compositions with the ratios of components 4:1, 3:1, 2:1, 1:1 were created. Tomato seeds have been dried using the convective method at the air temperature t = 50–80˚C, as well as the composition from red beets and pulp of tomatoes – at t = 60–100 ºС. The quality of dried seeds was estimated on the basis of its germinability, dried mixtures – on the content of betanin in them. When the temperature of the air increases, the intensity of tomato seeds drying increases too. Thus, the drying time reduces by 2.5 times when the air temperature is raised from 50 to 80 °C. However, qualitative seed material, which gives the germinability of 98%, has been attained at the drying temperature of 50 ºС. Non-waste processing of tomatoes involves the creation of compositions of pulp tomatoes and sliced red beets, their drying, grinding and packing. In industrial conditions, red beets need to be cut into chips, which intensifies the drying process of the composition. The slicing of tomatoes in compositions does not affect the process speed. When the air temperature increases from 60 to 100 °C, the intensity of compositions drying is raised by 1,8 times. Maximum preservation of the useful substances in the finished product results from the choice of a soft drying condition and an air temperature of 60°С. pH = 3.9 is characteristic for the ratio of red beet-tomato components 3:1 in composition, which ensures the maximum preservation of betanin (94.7%) at drying. The heat carrier temperature substantially affects the tomato seeds germinability and antioxidant properties of tomato and beet processing products.Документ Обоснование целесообразности использования надземной части свеклы в производстве оздоровительных пищевых продуктов(2014) Симахина, Галина АлександровнаПриведены результаты экспериментальных исследований белкового и полифенольного состава надземной части столовой, сахарной и кормовой свеклы, обоснованы перспективы ее использования для обогащения традиционных пищевых продуктов. This article represents the results of experimental researches on amino-acid compound of over-ground part of sugar, forage, and red beets, which helped the authors to prove the perspectives of its usage to enrich the traditional foodstuffs.Документ Перспективы развития нанонауки и нанотехнологии в маслоделии(2010) Рашевская, Тамара АлексеевнаНаноструктуру сливочного масла изучали методом сканирующей электронной микроскопии. Установлено, что внесение криопорошка из красной столовой свеклы способствует уменьшению величины элементов его наноструктуры в 5…25 раз относительно масла без добавок. В МБ формируется ячеистая наноструктура, состоящая из многогранных ячеек величиной до 100 нм, предложен механизм ее формирования. Установлено целесообразность использования небольших доз криопорошка из красной столовой свеклы для управления формированием наноструктуры сливочного масла и, соответственно, его качеством и физико-химическими свойствами. Результаты исследования могут быть использованы для создания пищевых нанотехнологий продуктов функционального назначения, в частности, сливочного масла.Nanostructure of butter was studied by scanning electron microscope method. It is proved, that the addition of red beet cryopowder makes nanostructure elements 5…25 times smaller than they are in butter without additives. The cellular nanostructure is formed in butter with red beet cryopowder. It contains many-sided cells about 100 nm. The mechanism of cellular nanostructure formation was suggested. The expediency of usage of low dose red beet cryopowder in order to operate butter nanostructure formation, butter quality, physical and chemical properties of butter was shown. The results of this researches can be used for functional food nanotechnologies creation and butter as well.
