HERBS AS A SOURCE OF NATURAL PRESERVATIVES AGAINST RANCIDITY IN THE LOW-MOISTURE BAKERY PRODUCTS

In recent years, it is a global trend of avoiding the use of synthetic ingredients for the food products quality enhancement. In this case it is actual task to search for the alternative natural raw materials, which provide the stabilization the products quality during storage. Due to their chemical composition, physiological and functional-technological properties the usage of herbs is a perspective solution of this problem. The aim of the study was to evaluate the effectiveness of natural ingredients based on herbs (powder and extracts) on the rancidity retardation. The antioxidant effect of herb raw-materials (hop, chamomile, nettle) was studied for the low-moisture bakery products with high fat content. These products are the ideal type of “food on the go” with long term of storage, which characterized with increasing popularity among modern consumers. The study was conducted at the Odessa National Academy of Food Technologies labs. The peroxide value of samples was determined by iodometric method (ISO 3960:2017). The results revealed that addition of natural antioxidants to the bakery goods in comparison to products without additives reduced this indicator up to the 37…52 %  for the samples with herbs. It has been determined that hop, chamomile and nettle incorporation have pronounced antiseptic properties also. The use of herbs in the low-moisture bakery products technology leads to the quality stabilization during their shelf life, improvement of nutritional value and it may be more attractive to consumers due to their natural origin

Management of Ecological Land Destructions as a Basis for the Formation of Green Marketing

The article deals with the assessment and management of ecological land destruction, taking them into ac-count when determining the market value of land and the formation of green marketing. Based on the research, the authors proposed the use of the concept of ecological land destructions, which reflects any anomalies that occur in the conditions of use of agricultural land. The authors propose a methodology for calculating the integrated coeffi-cient of ecological land destruction, which combines coefficients that take into account the ratio of agricultural land in the landscape, the optimal set of crops in field crop rotation, effective soil fertility, arable land degradation and soil degradation. It is substantiated that the application of the integrated coefficient of ecological destruction has a significant corrective value in the context of determining the market value of land

Удосконалення системи технічної діагностики та екологічно безпечної експлуатації ґрунтових гідротехнічних споруд на малих річках

This paper reports the results of studying soil hydraulic structures (SHS) of the CC1 class of consequences on small rivers. The representativeness of the results for the domestic and world practice of further operation of such structures is ensured by the typical technical and technological approaches to the construction, materials, and conditions of their work. Dams are built of soil materials and operated over significant time periods while their standard service life has been exhausted, which increases the environmental and technical danger of their further operation. Visual surveys were conducted and the technical condition was instrumentally diagnosed by the geophysical method of the earth's natural pulsed electromagnetic field (ENPEMF); observational data were mathematically treated. The possibility of arranging areas of increased water filtration through the SHS body was substantiated, as well as watering, loosening, and suffusion; potentially dangerous zones prone to landslides, cracks, and collapse were determined. The probability of risk of an accident on dams was estimated at their cascading arrangement as a result of filtration deformations of the body and the base of the structure. Under current operating conditions, the possibility of letting the normative and excess (forced) water volumes through water discharge facilities due to precipitation or a breakthrough of the structure located upstream was estimated. The proposed approach makes it possible to manage the cascade of hydraulic structures at different stages of operation: planned, operational decision-making, forecasting. This allows diagnostic examinations to be performed in order to identify structures that require priority in raising funds for repair and restoration work or demolition (dismantling)Представлені результати досліджень ґрунтових гідротехнічних споруд (ГТС) класу наслідків (відповідальності) СС1 на малих річках.

Diurnal variation in the convection-driven vertical distribution of phytoplankton under ice and after ice-off in large Lake Onego (Russia)

When sunlight penetrates the ice layer covering lakes in winter, it warms the top water layer and sets up convection, with several potentially contrasting effects on phytoplankton. While convective mixing keeps cells in suspension and prevents sedimentation losses, it may also transport phytoplankton well below the euphotic zone. We investigated diurnal variations in the vertical distribution of phytoplankton under ice and just after ice-off in Lake Onego (Russia), a lake with moderate to high colored dissolved organic carbon (CDOM) levels. We showed that diurnal variation in convection under ice restricts phytoplankton access to light in the morning hours to a narrow euphotic zone, whereas cells are mixed through a deep aphotic layer in the afternoon. After ice-off, low chlorophyll a was found on the open-water side of the thermal bar as convection distributed cells throughout the water column. By contrast, the inshore side had significantly higher concentrations of chlorophyll a (p < 0.001) because the mixing depth brought about by diurnal microstratification was reduced, resulting in greater access to light in the afternoon. Overnight, convective cooling broke down microstratification, which redeveloped the next day. Our work highlights the importance of studying diurnal variation in light availability for photoautotrophic growth, both under ice and after ice-off in lakes characterized by high CDOM
