Modern food products provide no more than 5-6% of the body's need for micronutrients, many of which are antioxidants. The current state of the problem of nutritional deficiency predetermines a chronic long-term deficiency of antioxidants in the diet. Providing the body with balanced polyvalent antioxidant complexes and normalizing its antioxidant status is the basis of health and active longevity.

In recent years, great interest has been focused on using natural antioxidants in food products, due to studies indicating possible adverse effects that may be related to the consumption of synthetic antioxidants. A variety of plant materials are known to be natural sources of antioxidants, such as herbs, spices, seeds, fruits and vegetables. The interest in these natural components is not only due to their biological value, but also to their economic impact, as most of them may be extracted from food by-products and under-exploited plant species. This article provides an overview of current knowledge on natural antioxidants: their sources, extraction methods and stabilization processes. In addition, recent studies on their applications in the food industry are also addressed; namely, as preservatives in different food products and in active films for packaging purposes and edible coatings.

Edible oils like sunflower oil, rapeseed oil, soybean oil, cotton seed oil and olive oil are necessary components in human diet and are extensively utilized in the food trade. Safe storage of edible oils has perpetually been a haul within the food industry since the oils can easily endure oxidative deterioration. Studies specializing on polyphenols as a supply of natural antioxidants of plant origin to delay oxidative deterioration of food products have increased worldwide. Both natural and synthetic antioxidants are widely used in protecting oils against oxidative deterioration. Natural antioxidants are greener preservatives because they are known to be safer than their synthetic counterparts. Currently there is an increased interest in sources of natural antioxidants to enrich oils towards shelf life enhancement. This review highlights some research works in which natural antioxidants from plant materials have been used to preserve edible oils. Most of the natural compounds extracted from medicinal plants were found to be able to preserve edible oils against oxidative deterioration. The potential of most of the natural antioxidants from plant materials to preserve edible oils was found to be comparable to that of synthetic antioxidants in all the reviewed researches. Use of natural antioxidants from plant materials for preservation of edible oils is a promising approach that can be adopted by edible oil manufacturers.

The objective of the study was to evaluate the presence of lead in several food products of plant origin. An atomic absorption spectroscopic quantitative method for the analysis of Pb+2 was developed and validated using an Analytik Jena ContrAA 300 apparatus equipped with an air-acetylene flame and a high-resolution continuum source. The analyzed food products were wheat, wheat flour, onions, corn, corn flour, carrots, beans, potatoes and cabbage grown in three geographical areas, on three soil types. The results obtained were in line with the limits laid down in Commission Regulation (EC) No 1881/2006 - Consolidated acts as far as the maximum admissible level of Pb+2 in foods.

The first half of the 20th century is characterized by discoveries in the field of biochemistry. During this period, the active substances necessary for the development of the body and maintaining homeostasis were first studied. After a long study of vitamins, scientists discovered a number of substances that have properties similar to vitamins, later they were called "vitamin-like substances". The mechanisms of regulation of the body's vital activity are always based on the course of special biochemical reactions, including with the participation of vitamin-like substances, which, unlike vitamins, can be synthesized by the body itself endogenously and come from exogenous sources (inside with food or in laboratory/industrial conditions). There is a need to maintain their balance through food intake. The article examines the role of vitamin-like substances of plant origin in the processes of vital activity of the organism, ensuring the implementation of specific tasks in the system of organs, cells and tissues. Due to the low quality of modern products, the concentration of useful components in their composition is reduced. Therefore, many people currently do not receive additional vitamin-like compounds and vitamin supplements are necessary to replenish them. The latter, due to the intense rhythm of life, people may forget to use or take irregularly. Therefore, the urgency of enriching the composition of familiar food products, in particular by means of yeast cultures, which are able to accumulate useful components in themselves, depending on the substrates consumed, has increased. The aim of this work is to study the possibilities of using yeast cultures to enrich the composition of familiar food products with vitamin-like substances from plant sources. Materials and methods. The article analyzes the possibilities of enriching familiar non-alcoholic food products by cultivating yeast cultures on substrates of plant origin. The role of vitamin-like substances in the biochemical processes of the body in comparison with the biologically active fermentative of yeast has been determined. To perform a systemic in-depth analysis, a synergistic principle was used to study the effect of the vitomin-like substances used on biochemical processes, that is, an analysis was carried out by studying the self-organization of the functional systems of the body without taking into account data on specialized pharmaceutical therapy. The research was carried out on the basis of the relevant Russian and English language information sources. Results. To achieve this goal, the reasons for the need and indispensability of vitamin-like substances in the biological processes of the body were initially considered, their classification and dosage were briefly characterized. Further, the methods of enriching food products by means of yeast cultures are studied in detail and the influence of each compound or group found in information sources on the biochemical processes in the body is considered. The possibilities of using yeast as a source of vitamin-like substances and for carrying out the fermentation of plant objects for enriching food products and non-alcoholic beverages with special components are considered separately. The composition and benefits of the active fermentative of yeast have been investigated, it has been established that the composition of the vitamin-like substances of the final product has not been sufficiently studied. It was revealed that successful attempts are being made to use Saccharomyces cerevisiae for the formation of food products enriched with bioflavonoids with antioxidant properties.
