Задача производства экологически чистых продуктов питания стоит в ряду важнейших мировых проблем. Она обусловлена целым рядом вопросов медицинского, социального, экологического и экономического порядка, объединенных актуальностью сохранения здоровья населения. Решение задач обеспечения сохранности продовольственного зерна пшеницы может осуществляться не только на базе действующих нормативных правил, но и с учетом результатов новых исследований. Разработана методика определения норм свежести (безопасного хранения) и годности зернопродуктов по значению кислотного числа жира (КЧЖ). Огромное влияние на зерно оказывают микроорганизмы, при этом количество плесеней хранения не нормируется для продовольственного зерна. Учитывая, что в любой зерновой массе присутствуют микроорганизмы, которые при определенных условиях развиваются по экспоненциальной кривой, авторами статьи была экспериментально установлена зависимость изменения КЧЖ от микробиологического показателя. Приведены результаты изменения биохимических, физико-химических и микробиологических показателей качества продовольственного зерна пшеницы урожаев 2015 и 2018 гг. при длительном лабораторном хранении в условиях повышенных (+30 °С), умеренных (+20 °С) и пониженных (+10 °С) температур. Установлено, что при хранении продовольственного зерна пшеницы при различных влажностно-температурных режимах в течение 24 мес происходит линейное увеличение показателя КЧЖ. Хранение зерна происходило в лабораторных условиях, определена зависимость изменения КЧЖ от температуры хранения зерна, а также неизменность показателя от развития плесеней хранения, что свидетельствует о возможности использования этого показателя для установления объективных и достоверных сроков безопасного хранения и годности. The task of producing organic food is one of the most important global problems. It is due to a number of medical, social, environmental and economic issues, united by the relevance of preserving the health of the population. The solution of the problems of ensuring the safety of food grain of wheat can be carried out not only on the basis of the current regulatory rules, but also taking into account the results of new research. A method has been developed for determining the norms of freshness (safe storage) and the suitability of grain products by the value of fat acidity value indicator (FAV). Microorganisms have a huge impact on grain, while the number of storage molds is not standardized for food grain. Considering that in any grain mass there are microorganisms that, under certain conditions, develop along an exponential curve, the authors of the article experimentally established the dependence of the change in the FAV on the microbiological indicator. The results of changes of the biochemical, physico-chemical and microbiological indicators of the quality of wheat food grain of the 2015 and 2018 harvests were given during long-term laboratory storage in conditions of increased (+30 °C), medium (+20 °C) and reduced (+10 °C) temperature. It is established that during the storage of wheat food grain under various humidity and temperature conditions a linear increase of the FAV arises within 24 months, change dependency FAV on grain storage temperature and indicator permanence on storage mold development are determined, which indicates the possibility of using this indicator to establish objective and reliable terms of safe storage and validity. Grain storage took place in laboratory conditions.

Concentrate Production

The problem of removing heavy and radioactive metals from the human body is relevant all over the world. Recent research has shown that it is more effective to use substances contained in natural food products, including pectin. Pectin has a favorable effect not only under acute exposure to metals, but also with their prolonged entry into the body, which is typical for an environmental load of residents of industrial regions and modern megalopolis. The use of pectin substances as natural detoxicants requires research to preserve these substances in products and further use. Therefore, an important condition for using pectin concentrates is to determine the shelf life for safe consumption. Based on this, studies were conducted to determine optimal storage parameters and terms for pumpkin concentrate. The sequence and parameters of pectin concentrate production from Karina pumpkin pomace are justified. As a result of the study, it was found that during storage of pectin concentrate from Karina pumpkin pomace at a temperature of 8 °C for 10 months, the pectin content in the concentrate decreased by 0–12. 45 %, at 25 °C – by 0–63 %, compared to the control sample. Based on the results, it can be concluded that the safe storage period of pectin-containing concentrates from Karina pumpkin extracts at a temperature of 25 °C is 7 months, at 8 °C – 10 months. As a result of mathematical processing of experimental data, equations for the relationship of pectin amount with storage temperature, pH and time are obtained.

SummaryStorage experiments were performed at 4°, 25° and 37° C with platelet-rich plasma under sterile conditions. In some experiments also the effect of storing platelets at 4° C in whole blood was investigated.Before, during and after three days of storage, the platelets were tested at 37° C for their serotonin uptake and response to hypotonic shock. In addition some glycolytic intermediates were determined.A fair correlation was noticed between the serotonin uptake and hypotonic shock experiments. Both parameters were best maintained at 25° C. Also platelet counting, performed after the storage period, indicated 25° C as the best storage temperature. Determination of glycolytic intermediates did not justify any conclusion regarding the optimal storage temperature. Of the various anticoagulants studied, ACD and heparin gave the best results as to the serotonin uptake and hypotonic shock response, either with fresh or stored platelets. The use of EDTA resulted in the lowest activity, especially after storage.The results of these storage experiments in vitro, correspond well with those in vivo reported in the literature.

The price paid for corn is usually based on 15.0 or 15.5 percent moisture content. However, corn must be dried below 13 percent moisture to ensure safe storage for a year or more. In the U.S., such stored corn cannot be directly remoistened before selling it, but it can be mixed with moist new-crop corn. Accurate moisture measurement of mixtures of dry and moist corn is important to permit adjustment of blending ratios to maximize profitability, but grain moisture meters are less accurate for mixtures of wet and dry grain. This research evaluated the differences between dielectric-type moisture meter results for mixed and equilibrated corn samples at different moisture levels and different measurement frequencies. Equilibrated grain samples tended to give lower moisture results than recently mixed grain samples - especially in the 1 to 10 MHz region. These differences permitted detection of mixtures by using moisture measurements at two frequencies.
