Phenolic compounds contained in plants can prevent cardiovascular and oncological diseases that pose a serious threat to human health and life. Onion Allium cepa L. is a source of natural phenolic compounds This study investigates the effect of extraction temperature and duration on the total content of phenolic compounds in aqueous extracts of oni...

The aim of the study was to determine the biochemical indicators of several varieties of dark rice before and after malting. To determine and compare the degree of germination of different rice varieties under given laboratory conditions. Four varieties of rice were taken for the study: black rice “Southern Night”, red rice “Ruby”, red rice “Jasmin...

This study examines the changes in the chemical composition of the vegetative parts of plants belonging to the Rosaceae and Grossulariaceae families. The subject of the analysis were stems, leaves, and buds of raspberries, currants, and blackberries. Fermentation can increase the content of certain polyphenols in raspberries and blackberries, preci...

The use of secondary raw materials to obtain useful products is a relevant direction of research. So sunflower root remains in large quantities after harvesting sunflower. For example, in 2021, after harvesting sunflower, about 67 million tons of dry organic residues of this plant remained in the fields. The possibility to use sunflower roots for i...

Nutrition is one of the most important factors determining human health. Enrichment of food products with minerals, antioxidant compounds, and vitamins are relevant today. In this work, dry orange peel was used to enrich a fermented drink based on kvass wort with phenolic compounds and vitamin C. The following indicators were determined: the conten...

Today, most researchers believe that polyphenols have wide-ranging applications and protect the human body from many diseases. This paper studies the total phenolic content (TPC) and the content of heavy metals in the selected leaves of plants that athletes actively use as a supplement to a healthy diet. For analysis, blackberry, raspberry, currant...

The article investigates fructose biopolymers contained in the roots of Heliánthus annuus. The raw material has been analyzed in terms of the content of inulin and other accompanying components, which are both advantageous for developing new functional food products and challenging for inulin extracting. Because in the composition of preparations f...

The world community is concerned about the global climate warming, among the reasons for which the increasing amount of carbon dioxide emitted is being considered, and carry out a systematic work to reduce greenhouse gas emissions into the atmosphere. Carbon dioxide (CO 2 ) is one of six types of gases (along with others), the content of which shou...

The current study considers tackling iron deficiency and nutritional anaemia through consumption of functional iron-rich foods, which are produced from plant-based ingredients. The study proposes the approach of developing functional beverages recipes. It includes ingredients selection, formula calculation, drink sample evaluation and iron measurem...

The study examines the possibility of expanding the international market for low-alcohol products by modernizing the traditional probiotic drink made from grain raw materials, which is popular in Eastern Europe - kvass. In particular, it is proposed to solve this problem by developing a fundamentally new version of kvass based on orange juice, hone...

Native plant-derived polyphenols are widely represented in nature and are used by humans. Resveratrol is such a substance. Its antimicrobial, antioxidant and other useful functions are being actively studied, which creates the prerequisites for the discovery of its new properties and the explanation of existing ones. The proposed study provides dat...

The current state of the agro-industrial complex and the food industry allows to satisfy the needs of various consumers groups. Among those needs, functional foods enriched with beneficial nutrients are becoming more and more popular. Polyphenols are sometimes used as such additives. The bioflavonoid resveratrol, among the group of polyphenols, has...

The use of industrial waste as the secondary raw materials is relevant all over the world. The rice sediment is a byproduct of the rice soft beverage industry. The rice mash was obtained by the rice sediment fermentation with α-amylase and ethanol yeast Saccharomyces cerevisiae . The rice wort fermentation efficiency was estimated by rice mash etha...

The development of industrial waste treatment and disposal technologies requires the use of rapid analyses for quick and accurate assessment of the properties of waste and wastewater. Biotests allows quickly define the integral toxicity and can be attractive for screening studies. The purpose of this paper was to study the toxicity of samples of wa...

This study is devoted to the problem of improving the methods of pectin obtaining from apple pomace. The relevance of the study is dictated by the fact of formation of a large amount of waste when receiving apple juice. The output of apple juice at the enterprises of the processing industry is from 50 to 75%, therefore, 25-50% is waste. In our stud...
