Cement production belongs to the most important branch of industry. It is marked out by processing of great quantity of natural raw materials and of considerable energetic demand. Not only the intensification of the contemporary production processes is the permanent effort of the cement industry, but also the search for new energy less demanding methods. The paper is focused on one of the most important components of the intensification of cement production – on the preparation of raw meal. It mainly deals with the influence of granulometry and microhomogeneity of the input raw materials on the quality and economy of the process of production and on the final product. The study was carried out mainly by methods of optical microscopy and the determination of technological parameters of cements. It has been found that a change in granulometry of raw meal has a significant impact on the formation rate of the clinker phases. Subsequently, the grindability of the clinker and the strength of the cement are influenced, especially in the short-term hydration. Change of granulometry and homogeneity of raw meal can greatly optimize the quality and economy of the cement production process.

Pleurotus Ostreatus mushrooms are used as raw materials for public catering establishments. Features of the technological properties of this mushrooms affect the composition of operations and their parameters during mechanical processing and the choice of methods and features of thermal processing. Taking into account the peculiarities of the growth of this mushrooms and their morphological structure, a scheme of mechanical processing is presented. The duration and weight loss were determined for various methods of heat treatment. It was found that the weight loss during heat treatment decreases with an increase in the dry matter content. There is an inverse relationship between the content of bound water and the loss of mass: with an increase in the proportion of bound water, the mass loss during heat treatment decreases. It means that the weight loss during heat treatment of mushrooms is due to the loss of free water. Therefore when assessing the quality of raw materials at the stage of incoming control, it is necessary to control the content of dry matter in mushrooms, and take this indicator into account when developing formulations and establishing technological parameters, namely, losses during heat treatment.

The scientific article presents experimental data on the possibility of modification of the generally accepted traditional technology of pre-heat treatment of freshwater fish raw materials in the production of canned fish by developing an innovative method - dehydration with hydrochloric acid. Technological and rheological features of the muscle tissue of the object of study - silver carp, which is the most important object of aquaculture and commercial fish farming in Ukraine and in many other countries, require the use of pre-heat treatment. This technique is required to remove moisture from muscle tissue by denaturing sarcoplasmic proteins when the temperature rises above 95 C. Due to the high specific heat of fish muscle tissue, heat treatment is energy intensive and, consequently, not cost effective. In connection with the above promising direction of modification of preliminary heat treatment of raw materials of the fish industry in the production of canned fish should be the development and implementation of a new innovative energy-saving method of processing semi-finished products in the design of modern fish processing enterprises. The paper presents data on the effect of hydrochloric acid on the properties of muscle tissue of silver carp. This directional regulation of the moisture holding capacity in the direction of its reduction is possible by shifting the pH to the isoelectric point of muscle tissue proteins. The influence of such technological parameters as mass fraction of hydrochloric acid in the treatment solution, hydromodule (solution: raw material), temperature and duration of the process on the change of active acidity of muscle tissue of fish raw materials, and, accordingly, moisture binding capacity was established. Accordingly, the following technological parameters of the process were determined: mass fraction of hydrochloric acid - 0.1%, processing temperature 20–25°С, hydraulic module - 1:10, processing duration - 30 minutes. The introduction of the developed technological parameters of the innovative method of pre-treatment creates conditions in which the active acidity of muscle tissue is as close as possible to the isoelectric point of most fish proteins, which in turn provides minimum values of moisture binding capacity. Based on the obtained data, a technological method of pre-processing of fish raw materials in the production of canned fish has been developed, the use of which allows to completely eliminate energy-intensive thermal operation from the technological cycle, and accordingly significantly increase economic efficiency

A method is suggested for the determination of gallium in aluminium oxide and in raw materials for its production (aluminium sulphates, alums) by atomic absorption spectrometry with electrothermal atomization, based on direct injection of a suspension of Al2O3 in an ethanol-water 9 : 1 mixture into a tungsten atomizer. Suspensions of Al2O3 with known amounts of Ga embedded in the solid phase are found to suit best for calibration. Optimum heat treatment and atomization conditions are established. The behaviour of gallium in aqueous solutions and in Al2O3 suspensions during their heat treatment is compared for atomization in a tungsten atomizer and in a graphite furnace.

The increasing in tourist flow to the Republic of Crimea, as well as the acceleration of the pace of life of the population led to an increase in demand for finished fish culinary products. In this regard, there is a need to create a new fish culinary product of long-term storage from the raw materials of the Azov-Black Sea basin. The Black Sea mullet (Mugil cephalus) was chosen as fish raw material, the catch volume of which has been steadily increasing in recent years. Sous-vide technology - is a progressive technology, which is characterized by low-temperature modes of heat treatment, resulting in a product with unique organoleptic characteristics that are superior to traditional types of processing of fish raw materials. Fish and vegetables prepared using the sous-vide technology are distinguished by tenderness and juiciness, the aroma of the finished dish is enhanced. During the development of new product technology, the optimal technological parameters (temperature and process duration) were determined for heat treatment of fish fillet in vacuum based on mathematical modeling. The research was carried out on the equipment of the sector of technologies of processing of water biological resources of the department "Kerchenskiy" of the Azov-Black Sea branch of Russian Federal Research Institute of Fisheries and Oceanography. Heat treatment of samples was carried out in a water bath of LB-63 according to the plan of an experiment in the range from 55 to 70 ? with lasting from 15 to 30 min. For packing of a product the vacuum device Solis Vac Premium was used. A regression model was constructed consisting of the objective function determined by the microbiological index QMAFAnM. The software "STATGRAPHICS Plus Version 5.0" was used to plan the experiment and determine the optimal technological parameters of the fish culinary product..
