“…These components might contribute to the basic nutritional and pharmacological features of lotus seed. Many functional foods, such as buckwheat, oat, and date fruit, also contain abundant functional metabolites [25,26]. Compared with buckwheat [27], lotus seeds contain fewer flavonoids but more alkaloids and phenolic acids.…”

Lotus (Nelumbo nucifera) seeds are widely consumed as functional food or herbal medicine, of which cotyledon (CL) is the main edible part, and lotus plumule (LP) is commonly utilized in traditional Chinese medicine. However, few studies have been conducted to investigate the chemical components of CL and LP in dry lotus seeds, not to mention the comparison between wild and domesticated varieties. In this study, a widely targeted metabolomics approach based on Ultra Performance Liquid Chromatography-electrospray ionization-Tandem mass spectrometry (UPLC-ESI-MS/MS) was utilized to analyze the metabolites in CL and LP of China Antique (“CA”, a wild variety) and Jianxuan-17 (“JX”, a popular cultivar). A total of 402 metabolites were identified, which included flavonoids (23.08% to 27.84%), amino acids and derivatives (14.18–16.57%), phenolic acids (11.49–12.63%), and lipids (9.14–10.95%). These metabolites were classified into ten clusters based on their organ or cultivar-specific characters. Most of these metabolites were more abundant in LP than in CL for both varieties, except for metabolites belonging to organic acids and lipids. The analysis of differentially accumulated metabolites (DAMs) demonstrated that more than 25% of metabolites detected in our study were DAMs in CL and LP comparing “JX” with “CA”, most of which were less abundant in “JX”, including 35 flavonoids in LP, 23 amino acids and derivatives in CL, 7 alkaloids in CL, and 10 nucleotides and derivatives in LP, whereas all of 11 differentially accumulated lipids in LP were more abundant in “JX”. Together with the fact that the seed yield of “JX” is much higher than that of “CA”, these results indicated that abundant metabolites, especially the functional secondary metabolites (mainly flavonoids and alkaloids), were lost during the process of breeding selection.

“…Следует отметить, что в отличие от других злаков зерна овес имеет толстый слой клеточной стенки в субалейроновой области [7,10,15,18] и содержание многих питательных веществ не равномерно распространено по эндосперму, а смещено в сторону алейронового слоя [8,[10][11][12], что в свою очередь, определяет необходимость поиска эффективных технологических решений для их использования при производстве пищевых продуктов.…”

There has been a significant increase in the oat (Avena sativa. L) consumption recently due to the new scientific data on dietary properties of oats, high content of polyphenols, especially Avenanthramides, and some flavonoids with an antioxidant effect. However, the thick layer of the cell wall in the hypoaleurone area and the uneven distribution of nutrients over the kernel determine the need to find effective technological solutions for their use in food production. The use of whole grain and its sprouting could be one of the possible solutions. Sprouting breaks difficult to digest grain complexes, thus making nutrients available for plant development and easier for human body intake. In the framework of this study, we propose to activate the process of grain sprouting by ultrasonic treatment of water used for preliminary grain soaking. The research results revealed that the proposed method accelerates accumulating of polyphenolic substances, phenolic acids and total antioxidant capacity. The mass fraction of polyphenolic substances in Avena sativa L. samples preliminarily aged in water treated with ultrasound (315W) for 2 minutes was 2.811 mg CAE/g, which is 4.64 times more than the mass fraction of the reference non-sprouted sample. Accumulation of phenolic acids at different treatment modes was intensified by 30.5% and more compared to the non-sprouted grain. Mathematical processing of the total antioxidant capacity (DPPH) results established a reasonable mode of ultrasonic water treatment used for grain soaking - 400 W for 2 minutes, the total antioxidant capacity will be 2.254 mg TEAC / g. Thus, the ultrasonic effect can be recommended as an intensifier in grain sprouting.
