“…The selection of raw plant materials in our region reveals a great variety of unique species of wild, alien, and cultivated plants [26,27]. Green crops, grown in open and sheltered soil, have a complex of phytonutrients and can be a food ingredient [28][29][30].…”

Mint Plants (Mentha) as a Promising Source of Biologically Active Substances to Combat Hidden Hunger

Hidden hunger, also known as micronutrient deficiency, is a form of undernutrition, which is exacerbated when food security is fragile. However, the amount of phytonutrients in the diet can be increased by using underutilized species, such as fresh mint greens (Mentha). These plants have a high biological value due to the high content of biologically active substances. Plants of the genus Mentha, however, differ significantly in their chemical composition and, thus, nutritional value. The main objective of this study was to evaluate the content of phytonutrients in different Ukrainian species of mint: peppermint (Mentha piperita), horsemint (Mentha longifolia L.), silver-leaved horsemint (Mentha longifolia S.), and spearmint (Mentha spicata L.), and to determine their stability after drying and freezing. After studying the chemical composition of fresh, dried, and frozen plants of these species, it was established that Ukrainian mint species offer a robust set of phytonutrients and can be used as ingredients of the so-called “functional foods.” The biologically active substances in mint are concentrated during drying. Moreover, such raw materials are easily stored and used as an ingredient. However, the losses of ascorbic acid due to drying mint reach 70%; of carotenoids—approximately 10–15%; of chlorophylls—21–38%; and of phenols—19–29%. Peppermint and spearmint were observed to have higher stability of biologically active compounds. As for the freezing, the best stability of the chemical composition was demonstrated by field mint and spearmint samples. Therefore, a targeted selection of mint types and varieties prior to processing will allow preserving maximal preservation of a maximum amount of biologically active substances, increasing the content of phytonutrients in finished products, and preventing the development of hidden hunger.

“…After harvest, spelt spikelets require additional processing in a process that is commonly referred to as threshing (Kulathunga et al, 2020). Spelt spikelets are dehulled in specialist machines (Anders et al, 2020;Kulathunga et al, 2020;Mykhailov et. al., 2022) equipped with a wire mesh cylinder and a rotor with beaters.…”

Spelt is one of unprofitable wheat types and requires an additional hulling process, in which the husks are removed from the grain. A device for dehulling spelt kernels was proposed. The described solution consists of a stainless-steel wire mesh cylinder with 4×20 mm and 4×30 mm longitudinal openings and a rotor with adjustable blade angles. Kernels were dehulled at the following angular speeds of the shaft: 16.76, 23.04, 29.32, 35.60, and 41.89 rad·s−1, and the following rotor blade angles: 50°, 60°, 70°, 80°, and 90°. The efficiency of glume and glumelle removal, the proportion of damaged kernels, and kernel and husk separation efficiency were evaluated during the experiment. The highest of kernel separation efficiency η z was 81.86% using a wire mesh cylinder with 4×30 mm longitudinal openings and 81.60% for a wire mesh cylinder with 4×20 mm longitudinal openings.
