Investigation of changes in chemical composition and rheological properties of Kyrgyz rice cultivars (Ozgon rice) depending on long-term stack-storage after harvesting

Camilya SMANALİYEVA | Kalıypa SALİYEVA | Bakıt BORKOYEV

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 endospe ...Более

Analytical and rheological investigations into selected unifloral German honey

Camilya SMANALİYEVA

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 effectiv ...Более

Investigation of changes in rheological properties during processing of fermented cereal beverages

Canıl İSKAKOVA | Camilya SMANALİYEVA

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 ...Более

Determination of physicochemical parameters, phenolic content, and antioxidant capacity of wild cherry plum (Prunus divaricata Ledeb.) from the walnut-fruit forests of Kyrgyzstan

Camilya SMANALİYEVA | Canıl İSKAKOVA | Cıldız ÖSKÖNBAEVA

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 p ...Более

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

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 d ...Более

Comparison of Rheological and Colorimetric Measurements to Determine α-amylase Activity for Malt Used for the Beverage Bozo

Canıl İSKAKOVA | Camilya SMANALİYEVA | Asılbek KULMIRZAYEV

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 stati ...Более
