Масло грецкого ореха пользуется большим спросом из-за высокой пищевой ценности. Однако оно легко окисляется и часто теряет свой типичный аромат. Воздействие кислорода, света, влаги и высокой температуры приводит к окислению жирных кислот и, как было установлено, является основным источником привкуса и снижения качества грецких орехов. Целью данной работы было оценить эффективность различных методов для сохранения качества ядер грецких орехов при хранении. В этом обзоре были изучены самые последние исследования, опубликованные за последние десять лет. В обзорной статье проводится анализ исследований по сохранению качества ореха при х . . .ранении различными методами: ультразвуковая экстракция, охлаждение с использованием антиоксидантных консервантов и съедобных покрытий, упаковка в модифицированной атмосфере, комбинированные методы консервации, сублимационная сушка, термообработка, обжарка. Химический состав, жирные кислоты, ненасыщенные жирные кислоты (олеиновая, пальмитолеиновая, линолевая и линоленовая кислоты), антиоксидантные компоненты (токоферолы и фитостеролы), общее содержание флавоноидов (TFC), общее содержание полифенолов (TPC), белки и минералы грецких орехов были исследованы после сублимационной сушки и в процессе тепловой сушки. Были проанализированы химические параметры, связанные с повреждением при хранении: пероксидное число (PV), конъюгированные диены (CD, сопряженные триены (CT) и cодержание каротиноидов (CC). Также были проанализированы летучие соединения, связанные с окислением липидов, такие как нонаналь, гексаналь, бутаналь и (E) -2-гептеналь, которые увеличились во всех образцах во время хранения. В заключение рассматриваются перспективы и задачи исследований на будущее, а также даются рекомендации по сохранению качеств ореха во время хранения More less

The present work investigated the effect of long-term stack-storage after harvesting on selected chemical and rheological properties of Kyrgyz rice cultivars, Ozgon. The performance indicators of in stack-stored Ozgon rice samples after 4, 6, and 12 days was grain size, grain weight, color, moisture, total starch, amylose, protein, fat and ash contents, and mineral composition as well as the rheological properties of rice flour dough. The change of stored rice is caused by the organic modification of the starch structure, decreasing of moisture as well as proteolysis of proteins in the endosperm. The increase of fat and ash contents . . ., mineral composition, and bio-functional components such as γ-oryzanol indicated the diffusion of micro- and macronutrients from rice bran into the rice endosperm and, thus improvement of the nutritional value of the rice flour. These changes in chemical composition directly influence the physical properties, such as pasting and viscoelastic properties of the rice flour dough as well as the browning of the rice grain. - Keywords: Ozgon rice; Stack-storage; Rice flour; Chemical composition; Rheological propertie More less

The present study draws attention to arsenic (V) (As(V)), chromium (III) (Cr(III)), and chromium (VI) (Cr(VI)) heavy metal pollutants, which have negative effects on aquatic ecosystems and indirectly pose a serious threat to the health of living things in the environment. Homopolymer and copolymer hydrogels were synthesized by the UV polymerization technique using 2-acrylamido-2-methyl-1-propansulfonic acid sodium salt (AMPS) and 3-acrlylamidopropil-trimethyl ammonium chloride monomers, and a crosslinker aimed to improve the swelling properties and metal sorption of the prepared hydrogels. The swelling balance values of hydrogels we . . .re determined by the gravimetric method in deionized water and different pH values, and their structural characterizations were carried out by Fourier transform infrared spectroscopy (FT-IR) and thermal gravimetric analysis (TGA) techniques. Sorption efficiencies and sorption capacities of the synthesized hydrogels were determined using aqueous solutions containing As(V), Cr(III), and Cr(VI) heavy metal ions at 25 °C. It was determined that there was a significant increase in p(AMPS) (AM1)-based hydrogel's balance swelling value in deionized water compared to p(AP1) and p(AMPS-co-APTMACl) (AMAP1)-based hydrogels. The lowest equilibrium swelling value was reached in the AMAP1 hydrogel, and the main reason for this result was thought to be due to the closure of the active functional groups of the increased cross-links between AMPS and APTMACl monomer. When sorption results were examined, it was observed that the highest heavy metal ion removal for AM1, AP1, and AMAP1 was in As(V) metal. The highest metal ion holding capacity of AM1, AP1, and AMAP1 was found to be 494 mg/g, 2336 mg/g, and 1439 mg/g for As(V), 323 mg/g, 111 mg/g, and 276 mg/g for Cr(III), and 303 mg/g, 723 mg/g, and 554 mg/g for Cr(VI), respectively. Considering the swelling and sorption results, it is thought that the synthesized hydrogels will provide a significant advantage in the removal of heavy metal ions, which have negative effects on environmental pollution and live health.

В статье представлены результаты исследования психометрических показателей кыргызскоязычной версии шкалы удовлетворенности жизнью. Авторами была разработана кыргызскоязычная версия теста, получены новые данные о его психометрических показателях. Предметом исследования были психометрические показатели кыргызскоязычного варианта шкалы удовлетворенности жизнью - её надежность, валидность, внутренняя согласованность. В экспериментальной группе было 292 (70,4 %) девушки и 113 (29,6 %) юношей, обучающихся на разных курсах по пяти педагогическим направлениям (естественнонаучное, физико-математическое, социально-экономическое и гуманитарное . . ., педагагогическое) Кыргызского национального университета имени Жусупа Баласагына и Кыргызского государственного университета имени Ишеналы Арабаева. Исследования показывают, что удовлетворенность жизнью является важной составляющей психологического благополучия личности. Коэффициент внутренней согласованности кыргызскоязычной версии шкалы удовлетворенности жизнью был рассчитан как α = 0,751. Значение корреляции метода «тест - повторный тест» было рассчитано как 0,642. Положительная значимая связь была найдена между двумя результатами шкалы удовлетворенности жизнью. Получены взаимосвязи между статусами гендерной идентичности, возрастом, экономическим состоянием, курсом обучения и уровнем удовлетворённости жизнью студентов. В результате исследования выяснено, что кыргызская шкала удовлетворенности жизнью является достоверной и надежной More less

In this study, mineral nutrient and heavy metal (Al, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn) contents of the walnut kernels and their co-located soil samples collected from the four different zones of natural walnut forests (Sary-Chelek, Arslanbap, and Kara-Alma in Jalal-Abad Region and Kara-Shoro in Osh Region) in Kyrgyzstan were investigated. The highest concentrations for all elements determined in the soil samples were observed in the Sary-Chelek zone whereas the Arslanbap zone was found to be having the lowest concentrations except Fe and Zn. The highest concentrations in the kernels of walnut samples were found to be in . . . the Sary-Chelek zone for Ca, Fe, K, Mg, and Zn; in the Kara-Shoro zone for Cu; in the Arslanbap zone for Mn; and in the Kara-Alma zone for Na whereas the lowest concentrations were found to be in the Arslanbap zone for Ca, Fe, K, Mg, Na, and Zn and in the Sary-Chelek zone for Cu and Mn, respectively. Also, the levels of Al, Cd, Ni, and Pb in kernel samples could not be detected by ICP-OES because their levels were lower than the threshold detection point (10 μg.kg−1). Additionally, our data indicated that the walnut kernels from Kyrgyzstan have higher values for RDA (recommended daily allowances) in comparison with the walnut kernels from other countrie More less

Molecularly imprinted polymers (MIPs) are handmade receptors that mimic the binding of natural antibodies. In other words, MIPs can selectively bind to the target molecule and qualify as bio-inspired synthetic materials. Today, MIPs are used extensively and are being developed further for biological applications. High cost and time consuming techniques are compelling factors for the field of biochemistry, biomedicine and biotechnology (3B), and there is an urgent need for an alternative, cheap, easy to produce, fast and effective method in these fields. MIPs stand out as a promising way for this purpose. MIPs have superiorities such . . . as specific recognition specificity, excellent sensitivity selectivity and reusability. From this point of view, we examined MIP-related drug delivery studies, cell recognition, enzyme applications, in vivo applications, and applications for some important biomolecules. The aim of this review is to compile the utilizations, advantages, important developments and future expectations of MIPs for the fields of 3B.

The effectiveness of course videos needs to be analysed, and in doing so, it is important to consider the utilisation behaviours and opinions of learners. In this regard, this study was primarily conducted to analyse Kyrgyz learners' utilisation of videos in a general chemistry course provided at the university level. This study was conducted during the 2019-2020 spring term at a state university in the Kyrgyz Republic and was structured using a mixed-method approach. The total number of participants was 105 Kyrgyz learners studying at the undergraduate level. Quantitative data were collected through an online survey, which consiste . . .d of demographic questions and items related to the utilisation of chemistry videos. Qualitative data were obtained through in-depth interviews with 13 learners. It was demonstrated through the data that learners used chemistry videos for 1-2 h per week. Also, the learners' utilisation did not change with regard to their success from watching the videos. Learners' utilisation of the chemistry videos was based on five factors: intrinsic motivation, self-concept of ability, self-perception of conscientiousness, video use and expectations of an online video library. This study also provided results regarding Kyrgyz learners' problems and suggestions related to their utilisation of the videos More less
