Abstract The aim of the study was to evaluate cocoa beans quality produced in Cameroon, Ecuador, Nigeria and Ghana from safety position determining heavy and trace metals concentration and evaluating the oxidative stability of confectionery products prototypes (trials) with analysing cocoa beans. For evaluation of oxidative stability of confectionery products, the main ingredients - butter and cocoa beans kernels were tested making trials as milk chocolate prototype. The composition of confectionery ingredients affects quality of products; therefore it is very important to evaluate quality of raw materials in confectionery industry, as they are purchased practically in all regions of the world. Mercury, arsenic, lead, cadmium concentration was determined in whole cocoa beans as their presence in foods have toxic effect on human beings and their concentration are strictly limited as maximum residue limits for processing. Cocoa shells can be used as additive to confectionery products recipes therefore the object of the study was cocoa beans and cocoa shells. Analyzing cocoa beans quality indices there was established that lead, cadmium, aluminium and zinc concentrations vary in cocoa beans significantly. Differences in lead concentration in cocoa beans from Ghana, Cameroon and Ecuador were significant (p < 0.05) compared with concentration of lead in cocoa beans from Nigeria (p > 0.05). Cadmium concentration in cocoa beans from Cameroon was significantly different comparing with cocoa beans from Nigeria, Ecuador and Ghana (p > 0.05). Differences in aluminium concentration in cocoa beans kernels were significant (p < 0.05) in all analyzed samples. Concentration of zinc was higher in shells of cocoa beans, especially in shells of cocoa beans from Ecuador (p < 0.05). The presence of cocoa products in milk chocolate prototypes inhibited the speed of lipid peroxidation. The different trace and heavy metals concentrations in cocoa beans should be taken into account choosing ingredients and components for confectionary products production particularly those with high content of cocoa (chocolates, sweets, cocoa fillings, cocoa creams and others) with the aim to prevent oxidation process during shelf-life of products.

Необходимость разработки безглютеновых продуктов обусловлена ростом численности людей страдающих целиакией, распространенность которой составляет 1 случай на 100–200 человек населения. Решение проблем, возникающих при производстве безглютеновых мучных кондитерских изделий, делает актуальным поиск новых видов сырья, не содержащего глютен и способного улучшать потребительские свойства изделий. В качестве источника безглютенового сырья была выбрана гречневая мука (ГМ). Получено безглютеновое печенье из ГМ в сочетании с различными гидроколлоидами – камедями акации, трагаканта, гуаровой и ксантановой, которые по отдельности добавляли в образцы ГМ в количестве 1г/100 г, и исследовано его физико-химические и сенсорные свойства в сравнении с аналогичными свойствами печенья из пшеничной муки (ПМ). Установлено, что образцы ГМ с добавкой камедей имеют более высокое содержание влаги, а печенье, полученное из смеси ГМ с камедью по разработанной нами технологии, – большую толщину, массу и сниженную прочность при разрушении по сравнению с ГМ и печеньем, изготовленным из нее. При сенсорной оценке качества изделий, проведенной по девятибалльной гедонистической шкале, установлено, что самые высокие показатели качества имеет печенье из ПМ, самые низкие – печенье, приготовленное из ГМ. Внесение камедей улучшило сенсорные показатели изделий на основе ГМ. Лучшим признан образец печенья на основе ГМ с добавлением ксантановой камеди. Таким образом, использование гидроколлоидов улучшает водосвязывающую способность муки и сенсорные показатели изделия – цвет, аромат, вкус и дает возможность получить безглютеновое печенье достаточно высокого качества, сопоставимого с качеством печенья из пшеничной муки. The need to develop gluten-free products is due to the growing number of people suffering from celiac disease, the prevalence of which is 1 case per 100–200 people of the population. Solving the problems that arise in the production of gluten-free flour confectionery products makes it relevant to search for new types of raw materials that do not contain gluten and can improve the consumer properties of products. Buckwheat flour (BF) was chosen as a source of gluten-free raw materials. Gluten-free cookies from BF were obtained in combination with various hydrocolloids-acacia, tragacanth, guar and xanthan gums, which were separately added to BF samples in the amount of 1 g/100 g, and its physical and chemical and sensory properties were studied in comparison with similar properties of wheat flour cookies (WF). The purpose of this work is to obtain gluten-free cookies from BF in combination with various hydrocolloids – acacia gum, tragacanth, guar gum and xanthan gum, which were separately added to BF in the amount of 1 g/100 g, and to study its physical, chemical and sensory properties in comparison with similar properties of cookies from WF. It was found that the samples of BF with the addition of gums have higher moisture content, and the cookies obtained from a mixture of BF with gum according to the technology developed by us – a greater thickness, weight and reduced strength at destruction compared to BF and cookies made from it. In the sensory evaluation of the quality of products conducted on a nine-point hedonistic scale, it was found that the highest quality indicators are cookies made from WF, the lowest – cookies made from BF. The introduction of gums improved the sensory performance of BF-based products. A sample of BF-based cookies with the addition of xanthan gum was recognized as the best. Thus, the use of hydrocolloids improves the water-binding ability of flour and the sensory characteristics of the product – color, aroma, taste, and makes it possible to obtain gluten-free cookies of sufficiently high quality, comparable to the quality of cookies made from wheat flour.

Cocoa beans are raw materials of cocoa processed food products rich in protein and minerals. Availability of sufficient quantities greatly determines the nutritional quality of the food. One of the post-harvest processes affecting the protein and minerals contents in cocoa beans is fermentation. The purpose of this study was to determine the protein, macro, and micronutrients contents in fermented cocoa beans of PBC 123, BR 25, and MCC 02 clones with fermentation time variations for 24, 48, 72, 96, and 120 hours. Methods of analysis used Kjeldahl and Atomic Absorption Spectrophotometer. The results showed that clones, fermentation time, and their interaction affect protein, macro and micronutrients content in cocoa beans. The interaction between BR 25 clone and 48-hour fermentation time showed the highest protein content (13.34%). The highest macronutrients content were found in PBC 123 clone with 72-hour fermentation time for Ca, in MCC 02 clone with 24-hour fermentation time for Mg, in BR 25 clone with 72-hour fermentation time for Na, and in BR 25 clone with 24-hour fermentation time for K. The highest micronutrients contents were found in PBC 123 clone  with 96-hour fermentation time for Fe, in MCC 02 clone with 120-hour fermentationtime for Mn, and in BR 25 clone with 96-hour fermentation time for Zn. Variations  of protein,  macronutrients and micronutrients contents in cocoa beans were affected  by clone variety and fermentation time treatment.

Ensuring the required level of quality of products produced by textile enterprises involves not only the final (output) control of its quality indicators, but also ensuring operational control over the relevant characteristics of raw materials and semi-finished products in technological processes throughout the entire production chain of textile material. Within the framework of the functioning of the quality management system of a textile enterprise, when conducting operational monitoring of technological processes, appropriate automated technical controls are required, built with the use of modern information technologies. In this paper, in order to assess the quality of the carding process in the production of combed or carded yarn, a method is proposed for the digital study of the structural unevenness in the surface density of this type of non-woven material, based on the principle of determining the sectorial and radial characteristics for this quality indicator.

Abstract A simple, specific, high-throughput colorimetric method based on the reaction of 4-dimethylaminocinnamaldehyde (DMAC) with flavan-3-ols was developed to determine total procyanidins in selected cacao-based products. Extracts of defatted samples were dispensed into a 96-well plate and reacted with DMAC. The absorbance of the reaction products was measured at 640 nm and compared to commercially available procyanidin B2 as a standard. The use of the 96-well plates and a plate reader dramatically improved sample throughput. A standard protocol was established and used for further studies. The calibration was found to be linear from 1100 ppm. The DMAC reagent reacted relatively specifically to (–)-epicatechin, (+)-catechin, epigallocatechin, gallocatechin, the gallates of catechin, epicatechin, gallocatechin, and epigallocatechin, oligomeric procyanidins of cocoa up to n = 4, and A-type procyanidins. Little or no reaction occurred with cyanidins and representative compounds of phenolic acids, flavones, flavanones, flavonols, anthocyanidins, isoflavones, and stilbenes. Sample precision studies were carried out on 10 different test materials over several weeks, and yielded RSD values of 4.0 to 9.5%. The method was ring-tested in three laboratories using blinded test materials including cocoa beans, cocoa powder, chocolate liquor, dark chocolate, and milk chocolate. There was excellent agreement of the results between laboratories.

Разработана технология получения желейного мармелада повышенной биологической ценности с использованием пищевых волокон. В качестве объекта исследований выбран желейный мармелад как имеющий низкую пищевую ценность, большое до 70 количество углеводов. Для обогащения изделия использовали растворимые пищевые волокна олигосахариды в виде препарата инулина в количестве 6 по массе выхода, что соответствует характеристике изделия с высоким содержанием пищевых волокон согласно ТР ТС 022/2011. В качестве студнеобразователя использован желатин в количестве 7 к желейной массе. Определено оптимальное соотношение сахара и патоки 2 : 1 соответственно. Установлено, что при добавлении инулина в количестве 6 повышается вязкость желейной массы на 0,7 Па с, что не затрудняет процесс формования количество редуцирующих веществ увеличивается на 0,4, что не ухудшает качества изделий. Доказана возможность использования препарата инулина для обогащения желейного мармелада пищевыми волокнами и получения изделий функциональной направленности. The technology of obtaining jelly marmalade of increased biological value using dietary fibers has been developed. As an object of research, jelly marmalade was chosen as having a low nutritional value and a large amount of carbohydrates up to 70. For the enrichment of the product, soluble dietary fibers oligosaccharides in the form of the preparation of inulin were used, in the amount of 6 by weight of the yield, which corresponds to the characteristics of the product with a high content of dietary fibers according to TR CU 022/2011. Gelatin in the amount of 7 of the jelly mass was used as a gelling agent. The optimal ratio of sugar and molasses 2 : 1, respectively, determined. It was found that the addition of insulin in an amount of 6 increases the viscosity of the jelly mass by 0,7 Pa s, which does not complicate the molding process. Also, the number of reducing substances increases by 0,4, which does not worsen the quality of products. The possibility of using the preparation of inulin for the enrichment of jelly marmalade by dietary fibers and the production of functional products has been substantiated.

The range of food stuffs having a rich composition of useful substances can be greatly enhanced by using a great variety of wild plants growing in Siberia. Apart from familiar widely used wild mushrooms, berries and other wild plants a biennial herbage plant, namely, great burdock can be used. Precise requirements to safety of wild plants growing in Russia are not available in regulatory documents. This makes it much more difficult to pass the procedures of confirming the conformity of products. This also has a negative effect on the processes of harvesting, storage, processing and transportation of wild plant raw materials. The key goal of testing the quality of products is to ensure safety of food stuffs. This goal can be achieved by further study of wild plants and by establishing precise standards of safety.
