Abstract
Abstract: The composition of lipids derived by extraction with Freon 22 and enzymatic hydrolysis from berries, berry shells, and seeds of the Chuy sea buckthorn cultivar has been studied. The fatty acid composition and acid and peroxide values of the samples have been analyzed; the differential scanning calorimetry (DSC) melting curves have been examined. The DSC method has been found to be appropriate for determining the origin of raw materials and the production method for sea buckthorn oil. Keywords: sea buckthorn oil, the Altai Territory, production method, differential scanning calorimetry 1. INTRODUCTION Sea buckthorn berries are rich in vitamins, carotenoids, flavonoids, proteins, antioxidants, amino acids, fatty acids, and phytosterols [1]. The most valuable component of sea buckthorn berries is their oil. The oil from the sea buckthorn pulp and seeds is characterized by a high content of lipids, including tocopherols, 3tocotrienols, carotenoids, and ω-3 and ω-6 polyunsaturated fatty acids [2, 3]. The composition of the sea buckthorn seeds and pulp varies in accordance with the subspecies, cultivar, soil and climate conditions, origin, cultivation activities, harvesting time, and extraction method [3]. The aim of this study is to explore the possibility of identifying samples of sea buckthorn oil derived from different parts of sea buckthorn berries by differential scanning calorimetry (DSC).
