Wild fruits and berries from the walnut-fruit forests of Kyrgyzstan may hold nutritional and health benefits for humans. Since information on their nutritional value is scarce, physical properties and nutritional value of naturally occurring red, black, and yellow cherry plum fruits (Prunus divaricata Ledeb.) were evaluated. The wild cherry plums featured moisture contents between 81.07 and 85.87%, reducing sugar contents of 6.83-8.42%, alimentary fiber of 0.78-1.38%, ash contents of 0.48-0.74%, acidity levels of 0.97-2.31%, and ascorbic acid concentrations of 16.00-30.25 mg/100 g. The total phenolic concentrations of wild cherry pl . . .um fruits was determined at 177-365 mg/100 g expressed as gallic acid equivalents. The black wild cherry plum contained the highest amounts of polyphenols and anthocyanins among the analyzed samples as well as the domesticated Prunus varieties. The essential mineral profile indicated that zinc (Zn) featured the lowest concentrations with 0.05-0.18 mg/100 g, while potassium (K) was the most abundant mineral at 127.97-188.74 mg/100 g in all cherry plum samples. 100 g fresh wild cherry plum can contribute up to 26.4% of iron (Fe) to recommended dietary allowance. All these results indicate that wild cherry plum fruits can be beneficial for human nutrition. The determination of physical attributes and chemical composition of these fruits is essential to facilitate the establishment of product standards and to further promote the use of these products in the food industr More less

Article | 2018 | Вестник Воронежского государственного университета инженерных технологий80 ( 4 )

Питание является одним из главных факторов, обеспечивающих нормальный рост и развитие ребенка. В Кыргызстане проживает около 160 298 детей в возрасте до 1 года, для которых необходимо специальное детское питание и эта потребность обеспечиваются только за счёт дорогих импортных продуктов. Целью исследования являлось разработка рецептур и технологии новых фруктово-овощных пюре для детского питания с использованием местного сырья. Для разработки нового продукта были выбраны яблоки, груша, тыква. Особенность новых рецептов заключается в использовании рисовой муки и меда, которые являются источником легкоусвояемых углеводов. Оптимальная . . .рецептура была выбрана на основе результатов органолептического анализа. Изучены физико-химические и реологические характеристики пюре. Реологические параметры были получены с помощью реометра MСR-302. Кривые течения были получены при температурах 25, 35 и 45 C. Анализ тиксотропии проводился путем расчета площади гистерезиса. Для описания кривой вязкости применяли уравнения Оствальда де Виля, Кессона и Бингама. Kоэффициент достоверности аппроксимации уравнения Оствальда де Виля R2=0.9936 ? 0.9998 был самым высоким, поэтому оно использовалось для рассчета реологических параметров. Добавление узгенского риса в рецептуру плодовых пюре умеренно повышает вязкость. Разработанные пюре благодаря сбалансированному содержанию углеводов и органических кислот, обладают хорошими вкусовыми свойствами. Содержания каротиноидов (провитамина А) составляет 0,676 мг %, что обеспечивает суточную норму. Все разработанные пюре рекомендуются в качестве прикормa для детей с 6 месячного возраста More less

The objective of this paper was to study the fatty acid composition, and thermal and rheological behavior of Kyrgyz yak (Bos grunniens) visceral fats compared to visceral fats of cow (Bos taurus) and horse (Equus caballus). The result of the studу revealed that the content of saturated fatty acids (SFA) in yak fat was higher than those of unsaturated fatty acids (UFA) (about 58.3 and 38.0 %, respectively). The UFA content in yak fat was higher compared to cow fat (about 27.1 %) and lower than that of horse fat (about 60.0 %). The melting temperatures determined using DSC were found to be 55.18±0.71, 54.98±3.01, 37.60±1.92 °C for yak . . ., cow and horse fat, respectively. These results were close to the solid-liquid transition temperature determined by oscillation rheology (52.20±0.89 °C for yak, 53.56±3.53 °C for cow and 33.7±1.84 °C for horse fat). Rotational rheological measurements at 35 °C have shown that yak fat had shear thinning flow behavior with high a viscosity of 226 mPas compared to horse fat, which has Newtonian flow behavior with a viscosity of about 36 mPas (γ=100s-1). Results on properties obtained in this study will help to understand the contribution of yak fats to the structural properties of new products with these alternative fat sources More less

Article | 2009 | European Food Research and Technology229 ( 1 )

The physicochemical and rheological properties parameters of five German unifloral honey: false acacia, heather, sunflower, lime and rape (39 samples) were analysed to demonstrate the relation between botanical origin and material properties. The validity of the rheological constitutive equations by Herschel-Bulkley, Ostwald-De Waele and Newton was confirmed by varying temperature and crystalline state. Highly structured (crystalline) honey exhibits temperature dependent with all rheological anomalies (shear thinning, yield point and rheodynamic behaviour) and can described an average effective viscosity. Modern oscillation measurem . . .ents were used to determine the crystallization behaviour of honey. The results showed that crystallization of honey is depended on botanic origin, temperature and storage time. - Keywords: Honey Crystallization Shear rate test Oscillation tests Temperature-sweep Mixed phase behaviour More less

Many indigenous fermented foods and beverages consumed throughout the world are produced at home or in crafts enterprises. The production of fermented beverages on a large commercial or industrial scale requires clearly established technical and technological requirements. This study shows a novel way to investigate the optimal process parameters of the Kyrgyz traditional fermented beverage Bozo using rotational rheological parameters. Five significant process parameters were investigated like cooking of millet porridge, the mashing temperature, the mashing time under conditions of mixing and viscosity changes of the end product dur . . .ing storage. According to the gelatinization temperature of millet porridge, cooking parameters were recommended at T = 79 degrees C and t = 30 min. The optimum mashing temperature of millet porridge was determined to be 65 degrees C and mashing time under stirring conditions of millet porridge was found to be 10 min. The viscosity of the beverage Bozo was investigated after 7, 14 and 21 days of storage at 5, 10, 20, and 30 degrees C. The effective viscosity of Bozo was calculated using the Casson model, which increased from 39.67 to 51.25 Pa center dot s after 21 days of storage. The effect of temperature on effective viscosity of Bozo and the activation energy was calculated using an Arrhenius-type equation. The parameters obtained make it possible to provide food manufacturers useful information for boiling, mashing and storage parameters after fermentation as well as quality control of Boz More less

In the current study, rheological and colorimetric methods were compared for determination of α-amylase activity of grain malt, used for Kyrgyz traditional fermented beverage Bozo. The highest α-amylase activity determined by colorimetric method was found in barley malt (32.83 A), followed by wheat (32.09 A), and was lowest in millet malt (10.82 A) and maize malt (10.76 A). Rheological parameters of millet porridge without and with malt were studied. The liquefaction effect of millet porridge after addition of malt was determined with rotational and oscillatory measurements. Results from statistical analysis (partial least square re . . .gression PLSR) revealed that oscillatory rheological parameters (yield stress τ, deformation γ, and storage modulus G′) could be an effective indicator to predict the α-amylase activity of the investigated malt with R2 = 0.9572. Consequently, rheological oscillatory measurements were recommended as an alternative tool to determine α-amylase activity of grain malt.- Keywords: Bozo, α-amylase activity, Malting, Rheology, Oscillation test, Colorimetric method, Viscosity, Yield Stres 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

On the Temporal Stability of Analyte Recognition with an E-Nose Based on a Metal Oxide Sensor in Practical Applications

Ruslan ADİL AKAY TEGİN | Camilya SMANALİYEVA | Coşkan ILICALI

Article | 2018 | Sensors18 ( 2 )

The paper deals with a functional instability of electronic nose (e-nose) units which significantly limits their real-life applications. Here we demonstrate how to approach this issue with example of an e-nose based on a metal oxide sensor array developed at the Karlsruhe Institute of Technology (Germany). We consider the instability of e-nose operation at different time scales ranging from minutes to many years. To test the e-nose we employ open-air and headspace sampling of analyte odors. The multivariate recognition algorithm to process the multisensor array signals is based on the linear discriminant analysis method. Accounting . . .for the received results, we argue that the stability of device operation is mostly affected by accidental changes in the ambient air composition. To overcome instabilities, we introduce the add-training procedure which is found to successfully manage both the temporal changes of ambient and the drift of multisensor array properties, even long-term. The method can be easily implemented in practical applications of e-noses and improve prospects for device marketin More less
