MODERN TECHNOLOGIES FOR GRAPE STORING

abstract 1592005022 issue 159 pp. 319 – 333 29.05.2020 ru 179
The article gives a review of modern technologies of storage of grapes. The main tool for stabilizing the quality of grapes during transportation and storage is the use of sulfur dioxide (SO2), a gas that has properties that can inhibit non-enzymatic darkening, reduce the activity of enzymes, effectively control the development of Botrytis cinérea (a phytopathogen that causes gray rot) and acts as an antioxidant. Researchers pay particular attention to control the release rate of SO2, as it is important in the first stage storage to ensure supply of significant quantities of SO2 for a short period of time, which eliminates Botrytis spores that are present on the surface of berries and to stabilize the damages formed during transport and filling; the second step is to ensure a steady supply of the minimum quantity of the SO2, to ensure the control of microbiological spoilage. For a long storage time. To preserve the quality indicators of grapes during storage, it is possible to use a modified gas environment created in various ways, including through special types of packaging; forced saturation of the environment with gases such as oxygen, ozone or carbon dioxide. At the same time, to enhance the effect can additionally apply fungicides, antifungal ear Anti-mold®, etc. There are known technologies for complex processing of table grapes to combat post-harvest microbiological spoilage, which provide for the first stage of treatment with ozone or sulfur dioxide followed by spray treatment with Muscodor albus. An alternative to the use of SO2 is the use of essential oils and hypobaric treatment methods that ensure minimal environmental impact. Positive results during storage are provided by the use of medium-range ultraviolet radiation (UV-B) or short-wave radiation (UV-C), which positively affect the transcription of biosynthetic genes, providing an increase in the content of phenolic compounds and antioxidant activity of grapes, without affecting the content of dry soluble substances, the value of total titrated acidity and pH during storage. The analysis of modern technologies is of interest to practitioners and researchers who develop technologies for storing grapes

MODERNIZATION AND ENHANCEMENT OF MICROCLIMATE PARAMETER MANAGEMENT ARE THE BASIS OF THE V GENERATION GREENHOUSES

abstract 1231609129 issue 123 pp. 1930 – 1952 30.11.2016 ru 695
Protected soil of Russia which has been stagnant for a long time began to expand actively and to modernize. The State Program of protected soil development for 2015-2016 promotes it, according to which every year it is planned to introduce 200 – 215 ha of modern industrial greenhouses. There was set the task of production of 1 mln. tons of greenhouse vegetables by the Ministry of Agriculture of Russia to 2020. Existing greenhouses of the IV generation of the type "Venlo" takes about 2.2 hectares in the country and are successfully used by producers of vegetables, obtaining in a year-round period 700 – 720 thousand tons of vitamin production. At present time the special attention of greenhouse owners is paid to greenhouses of the V generation of the system UltraClima, ModulAIR, in which we modernized the system of microclimate parameter management allowing to eliminate the critical periods of management by thermal isolation in the second part of May to the end of summer. The offered systems allow essentially economizing energy expenses, considerably to increase the profitability of vegetable production at the expense of management by growth’s processes and plant development. The innovation solutions in a greenhouse construction on the example of the first Russian greenhouse with the system UltraClima constructed in the Lipetsk region are discussed in this article. There was shown the characteristic of a new analogous development of Russian engineers having a number of advantages in comparison with UltraClima

STUDY OF THE INFLUENCE OF TREATMENT WITH SULFUR ANHYDRIDE ON GRAIN QUALITY INDICATORS IN THE STORAGE PROCESS

abstract 1602006015 issue 160 pp. 194 – 208 30.06.2020 ru 144
The urgent task facing the agro-industrial complex is the improvement of storage methods for agricultural products and the development of new ones. One of the actively cultivated crops, characterized by a variety of species, valuable taste and medicinal properties – grape. It is possible to provide the population with fresh grapes of high quality through the introduction of effective storage technologies that reduce losses, preserve marketable properties and biological value. One of the effective ways to preserve the quality of grapes during storage is the use of sulfur dioxide (SO2). This gas inhibits oxidative enzymes in berries, thereby reducing the rate of development of the phytopathogen Botrýtis cinérea, which causes gray rot. At the same time, it is especially important to control the rate of release of sulfur dioxide, since at the beginning of storage it is necessary to ensure the receipt of a large amount of it, which will eliminate Botrytis spores present on the surface of the berries and stabilize the existing damage. Further, during the entire period of storage of grapes, sulfur dioxide must be supplied in minimal quantities. Such dynamics of SO2 emission can be ensured by the use of two-phase generators of sulfur dioxide. The article investigated the effects of sulfur dioxide generators on the quality of grapes during storage. The study also investigates quality indicators of grapes of several varieties zoned in the Krasnodar region under long-term storage
