In Russia, in the production of meat and sausage products, the food colour, named as Red rice, is use. Red rice is obtain by the cultivation the strains of the Monascus fungus on various carbohydrate substrates, for example rice. That Red rice may contain the mycotoxin citrinin, but neither the purity of the food colour nor the safety profile are regulated. The aim of this work was to study the physical and chemical properties of Red rice and to develop method for its determination in sausage products. The experiments were carried out on model and commercial samples of sausages. The samples were analyzed using spectrophotometry and highefficiency planar and liquid chromatography. Spectrophotometric analysis revealed differences in solubility, coloring power, spectral characteristics, composition and ratio of pigments in commercial samples of Red rice. The extraction parameters of colouring substances from sausages model samples were determined. It has been established that Red rice is extracted with chloroform, acetone, ethanol and its aqueous solutions. Petroleum ether was proposed for degreasing sausages. Red rice from sausages was extracted with acetone because it did not extract synthetic colours and carminic acid. It was found, that 90% of Red rice is extracted from samples of sausages by double extraction with ultrasonic treatment with a power of 128 W. High performance thin layer chromatography method and high performance liquid chromatography method for the Red rice identification was proposed. The content of Red rice in the extracts was determined by spectrophotometric method. The developed method for the determination of Red rice was tested on commercial samples of sausage products.

Natural minerals, such as bentonite, kaolinite, biotite, vermiculite, and glauconite, which have sufficiently high performance properties in the softening of industrial and waste water, softening and cleaning of heavy metals, are promising. To study the physical and chemical properties of glauconites from various deposits of the country, samples of glauconite mineral were brought from the Parkent, Bukhara, and Karakalpak mountain reserves, their physical and chemical properties were studied, compared with each other, and the optimal reserve was selected. The reserves of these deposits are sufficient and have the potential for industrial development. The purpose of this study is to compare samples of natural mineral reserves of glauconite and select the optimal deposit for raw materials. Methodology. Samples of glauconite minerals from the Parkent, Bukhara and Karakalpak mines were taken as the object of the study. Chemical, mineralogical, and thermal analyses were performed on the samples, and the fractional composition was determined. Scientific novelty. The main part of the mineral glauconite (50-55%) in the raw material is found in fractions of 0.08-0.125 mm. The most suitable raw material was the Parkent glauconite deposit, which has a relatively high content of potassium, which tends to exchange with other metals during the sorption process. The received data. Based on the conducted experiments, samples of glauconites from Parkent, Bukhara, and Karakalpak were subjected to chemical and mineralogical analyses. The maximum amount of the mineral glauconite was found in the fractions of the raw material (less than 0.125 mm). The most suitable deposit of raw materials for processing the mineral glauconite was selected and an environmentally friendly adsorbent was obtained.

The modified aromatic polyethersulfones are synthesized. It is shown that the property of the obtained polymers depends on the ratio of the starting monomers. The presence in the initial monomer of two chlorine atoms in combination with an unsaturated bond provides the polyethersulfones based on it with high fire resistance and good physical and chemical properties, including frost resistance.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
