Bioactive Substances with Antioxidant Properties in Agricultural Products

Dear Colleagues,

Research is increasingly focused on the production of secondary plant metabolites in agricultural products and their antioxidant effects in disease prevention. It is necessary to know more about their diversity and ways to increase their production in vegetables and fruits due to the potential increase in their nutritional value. At the same time, they also provide some protection for plants against various stressful situations. Their effects are essential for the proper functioning of the human body. This group of substances also includes polyphenolic compounds, carotenoids, minerals and vitamins, etc., which have antioxidant, antimicrobial, anti-insect, and many other effects. An important way to increase them is also the biofortification of horticultural crops with antioxidant trace elements (e.g., selenium) and products of organic origin (biostimulants), which became the subject of interest of many farmers and scientists at the end of the 20th century. They stimulate natural processes in plants, in which available studies have shown a significant effect on the quality composition and yield of horticultural crops. The papers published in this Special Issue will present the results of research in the field of biofortification of various types of horticultural crops with selected biostimulants and selenium, their impact on crops and antioxidants, and the use of essential oils of spices and medicinal plants to control decay and maintain the quality of agricultural products using their antimicrobial and antibiofilm activity and the antioxidant activity of little-known horticultural crops.
