Improvement Of Fruit-Berry Wine Technoloгy Based On Biocatalytic Processes, Umid Abdullayev, Shakhnoza Ziyaeva, Akmal Boboev

CHEMISTRY AND CHEMICAL ENGINEERING

In the conditions of Uzbekistan, an increase in the range of wines through the production of natural and environmentally friendly wines from fruit and berry raw materials, as well as the efficient use of raw materials and the production of export-oriented natural young wines is an urgent problem. Based on this, the purpose of this study was to improve the technologies existing in Uzbekistan for the production of fruit and berry wines on a biocatalytic basis, by stimulating zymogenic enzymes of raw materials and yeast exohydrolases. To achieve this goal, berries such as red cherries, strawberries, raspberries, currants and mulberries …

Research Of The Process Of Extraction Of Black Cumin Oil With Preliminary Heat Treatment, Jasur Farmonov, Murodjon Samadiy, Kamar Serkayev, Toyir Safarov, Changeng Liu

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the study is to increase the yield of oil from black cumin seeds. The results of studies of the influence of technological parameters - temperature and duration of drying of black cumin seeds on indicators of the yield of oil, cake and moisture removal from seeds are presented. The optimal technological parameters of the influence of the preliminary heat treatment process on the indicators of the maximum oil yield, acid number, color, and oil moisture have been established. The variable parameters were the temperature from 80 to 130 °C and the duration of the heat treatment process …

Development Of Technology For Producing Food Sweeteners From Stevia And Their Immunomodulating Effect, Isomiddin Bobaev, Маrkhаbоhон Makhmudova, Makhbuba Alimova, Alimdjan Sadikov, Shamansur Sagdullaev

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the study is to develop a technology for the production of food sweetener from stevia (Stevia rebaudiana Bertoni) - a plant of the Asteraceae (Compositae) family, cultivated in Uzbekistan using alcohol extracts. Diterpene glycosides were isolated from the extract - stevioside (1), rebaudioside A (2) and other biologically active substances. Pharmacological studies in mice have shown the presence of an immunostimulating effect in the alcoholic extract and in the individual diterpene glycoside, stevioside (1).

Simulation Of The Extrusion Process Oil Crops Waste, On The Example Of Flax., Mukhtar Tultabaev, Umyt Zhumanova, Aleksandr Borovski, Marzhan Kizatova

CHEMISTRY AND CHEMICAL ENGINEERING

The modern fodder base does not allow organizing a full and balanced feeding of animals, which leads to the use of the genetic potential of livestock productivity by only 40-60%. As a result of the work, the extrusion of waste of post-harvest processing of oilseeds growing in Northern Kazakhstan (flax) was carried out. In the process of work, an experiment planning matrix was drawn up, on the basis of which experiments were carried out on the extrusion of oilseed waste. The research results were processed and mathematical models of optimization were obtained.

Technology Of Obtaining A Food Additive From Citrullus Colocynthis And Its Hypoglycemic Activity, Isomiddin Bobaev, Маrkhаbоkhон Makhmudova, Khayrulla Bobakulov, Vladimir Syrov, Nasrulla Abdullaev

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the study is to develop a technology for obtaining a food additive for the extract of the pulp of bitter watermelon - Citrullus colocynthis, introduced in Uzbekistan as a hypoglycemic agent. Pharmacological studies have shown the presence of a hypoglycemic effect for aqueous and alcoholic extracts and 2-O-β-glucopyranosyl-cucurbitacin E in rats with alloxan diabetes mellitus. Cucurbitacins were isolated from the extract - cucurbitacin E, 2-O-β-glucopyranosyl-cucurbitacin E and other bioactive substances.

The food supplement obtained from bitter watermelon (Citrullus colocynthis (family Cucurbitaceae)) according to the developed technology showed a higher hypoglycemic activity compared to the drug arfazetin.

Research Of The Extraction Process And Stock Of Phenolic Compounds Of Localized Wine-Technical Red And White Varieties Of Grapes, Abdullayev Umid

CHEMISTRY AND CHEMICAL ENGINEERING

The aim of the study was to determine the technological stock of phenolic compounds in European technical grape varieties grown in the climatic conditions of Uzbekistan, used to produce white and red wines. UV-Vis spectrophotometric method determined the total content of phenolic compounds in localized wine-technical grape varieties. Using high performance liquid chromatography (HPLC), the qualitative and quantitative content of groups and subgroups of phenolic compounds was studied, biologically active components obtained in the process of their extraction were identified, and studies were carried out to analyze the types of phenolic compounds by chromatographic separation in certain wine-technical grape varieties. …

Effect Of The Use Of Activated Water On The Rheological Properties Of Milled Flour In The Preparation Of Local Wheat Grains Grown In Arid Climates For Varietal Grinding, Ravshanov Suvankul, Mirzayev Jamol, Saparov Bekhruz, Musaev Khasanjon

CHEMISTRY AND CHEMICAL ENGINEERING

The article discusses the analysis of studies on the effect of activated water on the preparation of wheat grains grown in an arid climate for high-quality flour grinding. The aim of the study was to study the effect of the use of activated water on the rheological properties of type IV wheat flour grown in arid climates, in the preparation of wheat flour for grinding. In a study of the strength of the gluten framework and the rheological properties of the dough increased by increasing the water absorption capacity of flour when using activated water at 80 and 100 Hz …
