Antiradical potential (ARP) is an important measure of food safety. In addition, it directly or indirectly affects the rate of occurrence of a number of human pathologies. Using a photocolorimetric analysis of DPPH (2,2-diphenyl-1-picrylhydrazyl) solutions, we estimated the antiradical potential of food raw materials, food concentrates, biologically active substances, and wild plants. We conducted approximately 1500 analyses of almost 100 food products selected from 11 food groups: vegetables, milk, meat, fish, cereals and bread, drinks (including tea and coffee), etc. With a confidence interval (CI) of 95%, the average values for animal products range from 15.87 to 18.70 ascorbic acid equivalents per gram of dry matter. For plant materials, the range is 474.54–501.50 equivalents when wild herbs are included and 385.02–408.83 equivalents without taking herbs into account. The antiradical potential of the biologically active substances we studied ranged from 706.84 to 847.77 equivalents per gram of dry matter, which makes it possible to use some of the components to repair products with low ARP values, for example, bread and baked goods, confectionery, milk and dairy products, carbonated drinks, and juice. In this study, a low ARP value is associated with a reduction in the shelf life of products and a deterioration in their organoleptic properties; therefore, we propose using ARP as an important reference for describing the quality of food products and raw food materials.

Background: The composition of polyphenolic compounds in various parts of the Rosebay willowherb (Chamerion angustifolium) has been studied in detail and published. A number of these compounds have sufficient antiradical activity (ARA) to create functional foods based on extracts from this plant that are preventive against free-radical pathologies in humans. Part of substances with antiradical activity (e.g., vitamins, polyphenol components) are destroyed during the technological processing of food raw materials, and the values of ARA drop in the finished food product concerning the initial values (before and after technical processing) are not fully evaluated. background: The composition of polyphenolic compounds in various parts of the Rosebay willowherb (Chamerion angustifolium) has been studied in detail and published.

Objective: The object of the study is to study the thermal stability of polyphenol components possessing ARA (dried at 60°C and 150°C) and evaluate their residual ARA in the finished food products, N-acetylcysteine (NAC), as one of the known antiradical, was used as a reference substance. objective: The object of the study is to study the thermal stability of polyphenol components (Chamerion angustifolium) possessing APA (dried at 60°C and 150°C) and evaluate their residual APA in the finished food products, N-acetylcysteine (NAC), as one of the known antiradical, was used as a reference substance. Methods: Spectrophotometric method was used to evaluate the change of ARA in prepared foods. Gas chromatography-mass spectrometry (GC-MS) was used as an additional method to evaluate the difference in the chemical composition of polyphenol components. method: Spectrophotometric method was used to evaluate the change of APA in prepared foods.

Results: The residual ARA in the finished products (for caramel and bakery products) was ≈ 23.9% for rapidly extractable substances, for polyphenol compounds ≈ 46.1%, and for amino acids and easily hydrolyzable substances ≈ 34.5%. result: The residual APA in the finished products (for caramel and bakery products) was ≈ 23.9% for rapidly extractable substances, for polyphenol compounds ≈ 46.1%, and for amino acids and easily hydrolyzable substances ≈ 34.5%. Conclusion: Rosebay willowherb extract and N-acetylcysteine are recommended for increasing the ARA (between 1.6 – 4.9 times) of foods with low ARA (confectionery, bread, or other heavily processed foods) and for diets and diets preventive of free-radical pathologies by adding polyphenolic plant components and cysteine derivatives. conclusion: Rosebay willowherb extract (Chamerion angustifolium) and N-acetylcysteine are recommended for increasing the APA (between 1.6 – 4.9 times) of foods with low APA (confectionery, bread, or other heavily processed foods) and for diets and diets preventive of free-radical pathologies by adding polyphenolic plant components and cysteine derivatives. other: -
