Amino acid composition of Indian sesame (Sesamum indicum) seeds

Introduction. Amino acids, including essential ones, enter the human body in a ready-made form, i.e. with food. Therefore, the amino acid characteristics of plant products are an important indicator of their nutritional value. Indian sesame (Sesamum indicum) seeds contain a valuable complex of biologically active substances and are a source of fatty oil that can serve as an olive oil substitute. In addition to the fatty oil, the sesame seeds contain lignin, sesamin, phenolic compounds, etc. Objective: to study of the qualitative composition and quantitative content of amino acids in the Indian sesame seeds. Material and methods. The investigation object was Indian sesame seeds harvested in the Kashkadarya Region of the Republic of Uzbekistan in 2017–2018. Paper chromatography and HPLC techniques were used. Results. The Indian sesame seeds were found to contain 20 free amino acids, including eight essential ones. The amino acid complex of sesame seeds had high levels of glutamic acid, leucine, aspartic acid, and serine. The total content of amino acids in the aqueous extract from sesame seeds was 11.0099 mg/g. The quantitative content of essential amino acids was 31.76% of the amount of amino acids. Conclusion. The qualitative composition of the amino acid complex of Indian sesame seeds and the content of individual amino acids were determined
