Study of relations between chemical, colour and fluorescence properties of raw and dried meat powders of cow and yak (Bos grunniens)

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

Gluteus medius, Longissimus thoracis, and Semitendinosus muscles from the cow and yak (Bos grunniens) reared in the Kyrgyz Republic were dried by convective (hot air) drying and freeze drying. The dried muscles were grinded into fine powders and along with raw muscles were evaluated for water activity (aW), chemical composition (moisture, fat, protein), colour characteristics (L, a, and b values), fluorescence of intrinsic fluorophores (tryptophan, vitamin A, and riboflavin). Processing of measured data tables using common components and specific weights analysis (CCSWA) showed close relations ...Более

Determination of amino acid profile of mare milk produced in highlands of the Kyrgyz Republic during the milking season

Ayçürök MACİTOVA | Asılbek KULMIRZAYEV

This study was carried out to determine the influence of milking season on amino acid (AA) profile and chemical composition of milk samples from Kyrgyz native breed mares under traditional pasture conditions. Milk samples were collected monthly from May to August 2014 from mares grazing at 2,200 m above sea level. The AA composition was determined by precolumn derivatization with diethyl ethoxymethylenemalonate in HPLC and 18 AA were determined in mare milk. The analytical parameters of linearity (0.01–4 μg/mL), precision of the method (0.26–4.88% relative standard deviation), derivatization p ...Более

Amino Acid and Fatty Acid Profile of the Mare's Milk Produced on Suusamyr Pastures of the Kyrgyz Republic During Lactation Period

Ayçürök MACİTOVA | Asılbek KULMIRZAYEV | Cıldızay ÖZBEKOVA | Aybek BODOŞOV

The high nutritional and health-promoting properties of kymyz, a traditional drink of nomads produced from mare's milk, are well-known and reported in literature. The composition of mare's milk is significantly different from that of cow and other ruminants. Fatty acid composition and amino acid profile of mare's milk produced at Suusamyr pastures of Kyrgyzstan were studied during four lactation months (May, June, July and August). The amino acid composition was determined by precolumn derivatization with diethyl ethoxymethylenemalonate (DEEMM) in high-performance liquid chromatography (HPLC) ...Более

Urgent Measures to Improve Food Quality and Safety Control in the Kyrgyz Republic

Asılbek KULMIRZAYEV

The chapter discusses the food quality and safety control system in the Kyrgyz Republic. Specifically, the chapter introduces current socio-economic situation, characterization of the domestic food market, and elements of the national food control system upon adopting a series of new regulations since 2004. The new food safety system is progressively setting up, but there are a number of problems that holds back the implementation of new approaches to the assurance of food safety. These problems are mainly related to the underdeveloped national economy and poor socio-economic status of the pop ...Более

Fluorescence spectroscopy for accurate and rapid prediction of meat composition

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

The potential of fluorescence spectroscopy was assessed to study cow, goat, sheep and yak meat. Meat samples were taken from muscles, viz. Gluteus medius (GM), Longissimus dorsi (LD) and Semitendinosus (ST). The moisture, fat and protein content of meat samples were measured. The emission fluorescence spectra of tryptophan (305-500 nm), riboflavin (410-700 nm) and vitamin A (340-540) were recorded directly on meat samples at 290, 382 and 322 nm, respectively. Principal component analysis (PCA), partial least squares regression (PLSR) and partial least squares discriminant analysis (PLSDA) were ...Более

Study of moisture content and water activity of rice using fluorescence spectroscopy and multivariate analysis

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

The potential of fluorescence spectroscopy for non-destructive and rapid measurement of moisture content (MC) and water activity (a(W)) of rice was examined. A total of n 15 samples of rice produced at different locations were studied. The emission fluorescence spectra of tryptophan (305-600 nm, excitation: 290 nm) and emission fluorescence spectra of riboflavin (410-700 nm, excitation: 370 nm) were collected from milled rice. MC and a(W) of the rice samples were measured. Spectral data were subjected to principal component analysis (PCA) and partial least squares discriminant analysis (PLSDA) ...Более

Composition, nitrogen fraction, and amino acid profile of mare's milk produced in the mountains and highlands

Ayçürök MACİTOVA | Asılbek KULMIRZAYEV

The study was carried out to determine the effect of 2 ecological regions and lactation period on chemical (P < 0.01) and amino acid (P < 0.01) composition and nitrogen fraction (P < 0.01) of mares grazing on pastures at 1700 m (vegetation is dominated by shrubs and sub-shrubs) and 2200 m (vegetation is dominated by grasses, forbs, sub-shrubs) above sea level. The animals were kept under extensive pasture conditions and received no additional feed supplements. Milk samples were collected monthly from May to July and from May to August from mares grazing at 1700 m (Mountains) and 2200 m (Highla ...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

Fluorescence spectroscopy as a non destructive method to predict rheological characteristics of Tilsit cheese

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

The objective of this study was to investigate the potential of fluorescence spectroscopy to predict rheological characteristics of semi-hard cheeses as yield stress (τL), flow stress (τF), storage modulus (G′) and loss modulus (G″) measured at linear-viscoelastic, yield stress and flow stress oscillation regions. Melting temperatures and chemical composition of the semi-hard cheeses were also predicted using fluorescence spectra. Principal component analysis (PCA) and partial least squares regression (PLSR) were applied to the fluorescence spectra to extract information on the rheological pro ...Более
