Item type:Наукова стаття, The advantages of using sublimation for preserving the antioxidant properties of cranberries(Tallinn: Scientific Route OÜ, 2024) Holiachuk, SerhiiAbstract The benefits of using the sublimation method for preserving the antioxidant properties of cranberries have been studied. Cranberries are known for their antioxidant properties, which help combat infections, reduce the risk of heart disease, and improve arterial pressure. This berry is particularly beneficial in prostate cancer. Most of the beneficial compounds in cranberries are found in their skin, which may lose its properties during traditional juice extraction. Drying is an alternative method for preserving antioxidants, but traditional methods can lead to a loss of product quality. Sublimation drying has proven to be the most efficient and innovative method, as it ensures the preservation of cranberry antioxidant properties. After the sublimation cycle, the final moisture content of the material is only 2–5 % of the initial content, guaranteeing the maximum retention of beneficial properties and the production of a high-quality product. This method is promising for maintaining the quality of raw materials during drying and preserving their medicinal properties.Item type:Наукова стаття, Development of technology and study of properties of gluten-free shortbread biscuits(Lutsk: LNTU, 2025) Holiachuk, Serhii; Hunko, Yurii; Fedorus, YuriiThe number of persons with gluten intolerance is rising in the modern world, which calls for the creation of specialised goods that may satisfy their demands. The aim of the research was to develop a recipe for gluten-free shortbread biscuits with cherry filling. The research was carried out using the expert method, sensory analysis and statistical methods of processing research data. To achieve this goal, it was proposed to use a mixture of almond and coconut flour as a raw material for shortbread buiscits. It had been determined that the development of gluten-free products required the implementation of innovative technologies, the incorporation of alternative ingredients, and the analysis of the properties of raw materials and final products. Various model compositions of shortbread biscuits were developed based on mixtures of almond and coconut flour with different proportions of the mixture components (MС1 – 75:25, MС2 – 50:50, MС3 – 25:75). A sensory analysis of the model compositions of gluten-free shortbread biscuits was carried out, and their organoleptic characteristics were determined. As a result of the studies, a sensory profilogram of model shortbread compositions was obtained, which can be used to determine, which model composition was characterised by the best indicators (it was found that MС1 had the best indicators). The brittleness index of gluten-free shortbread biscuits was also determined depending on the content of almond flour in the mixture. The physicochemical parameters of various model compositions of gluten-free shortbread biscuits were determined and the results of these studies were analysed. The development of gluten-free shortbread biscuits with cherry filling allows expanding the range of flour confectionery products with a healthful orientation
