The Impact

Subject of research – sugar content in rye bread with fractionally defatted flour from walnuts, pumpkin seeds, sesame and Jerusalem artichoke powder. The purpose – to investigate the chemical composition of sugars in flour from oilseed meal and to explain the impact of new raw materials upon the sugar content in bread made from rye flour. Materials and methods. For the production of pilot of bread used: rye flour; fermented rye malt; table salt; drinking water; ready liquid rye sourdough (composition: Lactobacillus plantarum 30, L .casei 26, L. fermenti 34, L .brevis and Saccharomyces minor "Chernorichenskaya", S. cerevisiae L1); fractionally defatted flour from walnuts, pumpkin seeds and sesame produced by PE "Research and Production Company "Elitfito"; Jerusalem artichoke powder "Dar". The dough was prepared in a three-phase way: liquid sourdough – saccharified choux – dough. Jerusalem artichoke powder and oilseed meal were added to the dough. The chemical composition of sugars in raw materials and bread was determined by high-performance liquid chromatography. The effect of fractionally defatted flour on the course of processes in rye dough was performed on a farinograph and amylograph of Brabender. The intensity of gas formation of the dough was determined on the device AG-1. Changes in the crystal structure of the bread crumb were performed using X-ray phase analysis on the device DRON UM-1 in the range of angles 2θ from 5 to 60 degrees. Results. It is established that the share of sugars in flour from oilseed meal is 2 ... 8 times higher than the content of sugars in rye flour. The content of sugars in fractionally defatted flour from walnuts is 43.0 %, from pumpkin seeds – 14.2 %, from sesame – 12.8% by weight of dry matter. Up to 80% of all sugars in fractionally defatted flour are sucrose and maltose. The ratio of fructose to glucose in fractionally defatted flour from walnuts is 1:1.25; from pumpkin seeds – 1:0.73; of sesame seeds – 1:0.5. The addition of 7.0 % fractionally defatted flour mixed with 3 % of the Jerusalem artichoke powder reduces the mass fraction of sugars in bread compared to the bread made with Jerusalem artichoke only. It has been studied that fractionally defatted flour from walnuts, pumpkin seeds and sesame reduces the hydrolytic decomposition of rye flour starch and promotes the process of fermentation of sugars. Scope. A mixture of fractionally defatted flour from oilseed meal in the amount of 7 % should be used for the production of bread from rye flour with 3 % Jerusalem artichoke powder to the mass fraction of flour to reduce the content of high glycemic starch sugars.

Исследовано влияние влажности табачного сырья, его сортотипа, количества в рецептуре на содержание массовой доли нерастворимой части в табаке для кальяна. Объектом исследования были образцы кальянных смесей разных торговых марок, приобретенных в торговой сети Краснодара и составленных в лабораторных условиях Всероссийского научно-исследовательского института табака, махорки и табачных изделий. Образцы кальянной смеси изготавливали по единой для всех образцов рецептуре и технологической схеме: увлажнение, резка, выдерживание в соусе с нагревом, охлаждение. Влажность и количество табачного сырья в рецептуре варьировали. Методом количественного определения содержания табака в готовом продукте, основанном на способности части ингредиентов кальянных смесей растворяться в воде, определяли массовую долю нерастворимой части. Установлено, что содержание массовой доли нерастворимой части в табаке для кальяна различных торговых марок, приобретенном в торговой сети Краснодара, составляет 5,2–8,8%. Сортотип табачного сырья, его химический состав и добавленный в смесь ароматизатор не влияют на содержание массовой доли нерастворимой части в табаке для кальяна. Содержание массовой доли нерастворимой части табака для кальяна в значительной степени зависит от влажности и количества табачного сырья, используемого в рецептуре. Увеличение влажности исходного сырья приводит к уменьшению массовой доли нерастворимой части в смеси для кальяна: при влажности сырья 10% массовая доля нерастворимой части 6,8%; при влажности того же сырья 16% массовая доля нерастворимой части 5,2%. The influence of humidity of tobacco raw materials, its variety type, and the amount in the recipe on the content of the mass fraction of the insoluble part in hookah tobacco has been studied. Samples of hookah mixes of various brands purchased in the retail network of Krasnodarand compiled in the laboratory of the All-Russian Scientific Research Institute of Tobacco, shag and Tobacco Products were the object of research. Samples of hookah mix were made according to the same formulation and technological scheme for all samples: humidification, cutting, keeping in a sauce with heating, cooling. The humidity and amount of tobacco raw materials in the formulation varied. By quantifying the content of tobacco in the finished product, based on the ability of some of the ingredients of hookah mixtures to dissolve in water, the content of the mass fraction of the insoluble part was determined. It is established that the content of the mass fraction of the insoluble part in hookah tobacco of various brands purchased in the retail network of Krasnodar is 5,2–8,8%. The variety type of tobacco raw materials, its chemical composition and added flavor to the mixture do not affect the content of the mass fraction of the insoluble part in hookah tobacco. The content of the mass fraction of the insoluble part of tobacco for hookah largely depends on the humidity and the amount of tobacco raw materials used in the formulation. The increase of humidity of raw materials leads to a decrease of the mass fraction of the insoluble part of hookah tobacco: if moisture content of raw materials 10% mass fraction of the insoluble portion of 6,8%; the humidity of the same raw materials 16%, the mass fraction of the insoluble portion of 5,2%.

ABSTRACTSpent fuel reprocessing by an innovative reductive extraction process in a molten fluoride medium (LiF/AlF3) is now being evaluated; in this hypothesis, all the unrecoverable fission products would be conditioned as fluorides. A preliminary study was undertaken to assess the feasibility of incorporating these fluorides by melting in a glass-ceramic matrix. The containment matrix for the fluorinated waste stream was selected after examining the consequences of fluorinated compounds on the vitreous state and on the physical and chemical properties of the melt and the solidified glass. The presence of fluorinated compounds in the raw materials used to produce the vitreous material raises the problem of the volatility of some fluorides, of their solubility in the melt, and of possible crystallization of the material.
