This article presents an analysis of the results of the study of flour obtained from batches of wheat grain at the stages of storage. It is shown that during the observed period of grain storage, the quality of the obtained wheat flour was stable and corresponded to the highest grade in terms of physicochemical parameters. Wheat of the 3rd class after 6 years of storage can be used for milling purposes for the production of bakery flour.

For wheat grain with long-term storage, a set of additional methods has been developed that make it possible to assess its quality, firstly, as an object of long-term storage, and secondly, as an object for processing into flour and making bread from it after a storage cycle. Improving the methodology for assessing the quality of grain is a promising and relevant scientific direction in the development of the technological foundations for long-term storage of grain.

In the world, the demand for quality and safe grain products is increasing. The need to preserve wheat in the event of a natural disaster requires the study of optimal storage times of grain without degrading technological indexes. The purpose of the work was to study the dynamics of technological properties of winter wheat grown after peas, clover, corn for silage and the industrial, ecological, biological growing systems during 1, 3, and 5 years of storage in the conditions of the ordinary granary. The absence of significant differences in the technological parameters of the grain of wheat grown at industrial and ecological systems, but significantly lower indicators at a biological growing system was found. The highest hectolitre weight obtained when wheat grain was grown after corn for silage, and vitreousness – after the clover. Significantly higher biochemical parameters of grain and alveographic properties of flour were for the cultivation of wheat after peas, which provided additional accumulation of protein substances. There are no significant changes in the indicator of hectolitre weight during the grain storage. Other indicators increased significantly after 1 year of storage (on average by 10 – 30%). For further storage, vitreousness growth was insignificant. After 5 years of storage, the falling number significantly increased (on 21% compared to the initial values and on 7% – after 3 years of storage). The content of protein, gluten in the grain, and alveographic properties of flour significantly decreased after 5 years of storage. The possibility of obtaining grain of wheat with high technological parameters for a more safe ecological growing system was established. It was also confirmed to need for grain storage up to 1 year to improve quality indicators and it was established that it safely stored for 3 years.

The main problems of grape storage are berry dehydration and rot. One of the solutions to reduce rot and preserve the quality of grapes during storage is the use of aerosol treatment with calcium content before storing. The aim of the study was to evaluate the effect of physiologically active substances based on calcium in various concentrations on the quality and organoleptic characteristics of table grape cvs. ‘Italia’ during long-term storage. The effectiveness of the studied systems of treatment was evaluated according to the content of sugars and titratable acids, the activity of the redox enzymes of polyphenol oxidase and peroxidase, weight loss of bunch and organoleptic properties. The greatest effectiveness established by using preparation of Master Green Ca, Brentax KCa, and Brentax Ca (in concentration 150g / 20l). Experimental treatments significantly decreased the weight loss of bunch (less than 4%), and preserved organoleptic properties of berry at a high level (8.2-8.9 points). Decrease in the activity of oxidative enzymes had a positive effect on the quality of table grapes and contributed to its better preservation. The data obtained make it possible to rationalize the system of long-term storage of grapes by using of aerosol treatment with calcium-based preparation.

The methodology in Latvia forest industry provide to determine the quality of energy chips only in long- term storage places before selling. Due to the lack of hard empirical data about the quality parameters of energy chips in different phases of manufacturing process, this research paper consists of: - the identification and analyses of the factors that influenced the values of energy chips quality features such as: bulk density, moisture content, ash content, higher and lower heating value according to actual moisture content and per dry mass of the chips; - the methodology for determination the quality parameters of energy chips by analysis the wood moisture content and by choice the method of the manufacturing of energy chips.

Due to the fact that milk has a short shelf life, the issue of its freezing and long-term storage in the frozen state is relevant. A study was conducted on the effect of freezing on the milk quality after its defrosting of cows-mothers and cows-daughters of Red-Motley breed. As a result, it was established how milk quality indicators to change after five months of storage in a frozen state in cows of two age groups. A high correlation was established between quality indicators before and after freezing. The influence of the “freezing” factor on milk quality indicators was recognized statistically significant, the “generation” factor – not significant.

The problem of utilization or recycling industrial tobacco wastes is an important problem for tobacco industry. Economically preferable way for utilizing industrial tobacco wastes (tobacco scrap) is production smokeless products and hookah blends as wastes are utilized without special treatment. Monitoring of humidity and fractional composition of cut tobacco taken from tobacco rod/cigarette spoilage (tobacco scrap) is carried. Its long-term storage leads to increasing scrap and dust quantity. Researches on utilizing tobacco scrap for sniff and hookah blend production, which are considered to be less harmful compared to cigarettes, were carried. Chemical composition of American type tobacco and scrap was defined. Nicotine content varies from 0.9 to 2.4% and carbohydrates content – from 5.6 to 9.6%. Experimental samples of hookah blend were produced and their organoleptic and taste evaluation were carried. It was found that utilization of tobacco scrap is economically efficient for hookah blend production, as quality of final product made of leaf tobacco and tobacco scrap is similar. Experimental samples of sniff tobacco were produced in order to discover possibility of utilization industrial tobacco scrap for manufacturing this product. Consumer’s properties of sniff tobacco were evaluated by 100 points tasting protocol. This technology for sniff tobacco production from tobacco scrap allows manufacturing product of good quality, decreasing technological operations, rejecting stages of tobacco selection and its cutting and as the result decreasing cost of final product. The results of the research on utilizing tobacco scrap for hookah blend and sniff tobacco production proves optimality of recycling the tobacco wastes.
