Nurzat ŞAYKİYEVA | Mirlan MOLDOBAYEV | Kubat KEMELOV | Canıl İSKAKOVA | Mustafa DOLAZ

Kyrgyzstan is a landlocked country in Central Asia, famous for its crystal-clear lakes, majestic Tien Shan Mountains that bisect the territory of Turkistan, and magnificent natural beauty. This study aims to evaluate the fruit (acorns) of the oak trees (Quercus robur L.) grown in Bishkek, the capital city of Kyrgyzstan. For this purpose, carboxymethyl acorn starch (CMAS), which is not synthesized in literature, is first synthesized by isolating acorn starch (AS) from the acorns. The structures of CMASs are characterized by H-1(C-13)-NMR, FT-IR, XRD, and SEM techniques. The viscosities of the s ...Более

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

Front face fluorescence spectroscopy as a tool for comparison of aromatic amino acids, nucleic acids, vitamin A and FMRP containing in different egg types

Mustafa Haluk ÇELİK

Fluorescence spectroscopy was used to determine contents of amino acids, nucleic acids, Maillard reaction products and vitamin A in whites and yolks of eggs from hens, geese, ducks and quail. The fluorescence spectra obtained varied between egg types and allowed the eggs to be grouped and differentiated from each other on the basis of their composition. Keywords: amino acids; duck eggs; ducks; eggs; fluorometry; geese; maillard reaction; maillard reaction products; nucleic acids; quail eggs; quails; retinoids; spectrofluorometry; spectroscopy; vitamin a; goose eggs

О возможностях использования мяса яка как перспективного профилактического продукта при дефиците йода и железа

Nurudin KIDIRALİYEV

Йод является важнейшим незаменимым микронутриентом. К районам с природным дефицитом йода в воде и почве относится практически вся территория Кыргызстана. Дефицит йода проявляется широким спектром различных патологических состояний. Наиболее неблагоприятные последствия от недостатка йода возникают на ранних этапах развития организма. Из-за снижения метаболической активности йододефициту часто сопутствует железодефицитная анемия - болезнь, связанная с недостаточностью железа в крови. В этом случае анемия обычно носит невыраженный характер и, как правило, проявляется уже в зрелой стадии гипотирео ...Более

The Oxidation Behavior of Potato Starch and Benzyl Alcohol via Peroxide in the Catalysis of Metal Complexes

Mustafa DOLAZ

Two new Schiff bases ligands (HL1 and HL2) and their Co2, Mn2, Fe3, Ru3, Cr3, and VO2 complexes were synthesized and characterized by FT-IR, 1H-NMR, and Mass spect. and analytical methods. A single-crystal X-ray diffraction study determined the molecular structure of HL1. The catalytic effects of metal complexes on benzyl alcohol and potato starch (PS) oxidation were compared in an H-2O-2 medium. The percent conversion of benzyl alcohol to benzaldehyde and benzoic acid was determined by Gas Chromatography. [Co(L-1)(2)], [Mn(L-1)(2)], [Co(L-2)(2)], and [Mn(L-2)(2)] showed the highest catalytic ...Более

Разработка фруктово-овощного пюре для детей в возрасте до трех лет = Development of fruit and vegetable puree for children under three years of age

Nurudin KIDIRALİYEV | Aybek BODOŞOV

В Киргизии проблемы, связанные с рациональным питанием детей в возрасте до трех лет, являются одними из главных. Несмотря на достаточный объем производимой сырьевой продукции, детское питание, предназначенное для детей в возрасте до трех лет, не производится в стране, а импортируется из ближнего и дальнего зарубежья. В данной статье приводятся разработанные 12 рецептур комбинированного пюре из местного сырья. В разработке комбинированного пюре для детей использовались яблоко, морковь и тыква. Для повышения содержания белков в продукте для детей применены зерна фасоли местных сортов «Рябая» с с ...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

Synthesis and Characterization of Hydroxypropyl Acorn Starch (HPAS) From Oak Acorn

Mustafa DOLAZ

The utilization of forest auxiliary products and their conversion into products with higher added value is important for the use of renewable resources. For this purpose, acorns belonging to the Q. coccifera species were collected in November, which is their ripening period, and dried and ground in the laboratory. Then, acorn starch (AS) was isolated from the sieved acorn flour. For 5 g of this isolated AS, hydroxypropyl acorn starch (HPAS) with the highest molar substitution (MS = 0.319) was synthesized by optimizing at 45 degrees C for 5 h with 30 g of propylene oxide and 1.88 g of NaOH. The ...Более

Synthesis and Characterization of Hydroxyethyl Starch from Chips Wastes Under Microwave Irradiation

Mustafa DOLAZ

This article focuses on the synthesis of hydroxyethyl potato starch (HEPS) for liquid hand soap by evaluating waste potato starch (WPS), a byproduct in potato chips production. It is a cheap, biodegradable, non-toxic and renewable natural polymer, available in great quantities on a global level. In a factory producing potato chips, WPS, which remained in the aqueous medium during peeling, slicing, and washing the potatoes, was purified at the desired temperature with H2O2 and NaOH. HEPSs with the molar substitution (MS) in the range from 0.298 to 0.670, were synthesized under microwave irradia ...Более
