To achieve the aim, the following tasks were identified： （I） study the physicochemical, biochemical properties and the composition of amaranth seeds; （2） improving the methods for producing the oil extract of amaranth. This article is devoted to complex research of processes of manufacture of vegetable oils. Authors have developed scientific bases of improvement and an intensification of technological processes for production of oil from amaranth seeds. The authors have developed a new technology for extracting of oil from amaranth seeds using hexane as a solvent. The proposed method provides to obtain oil without great technical effort and keeps it all the nutrients that promote the highest taste of the product and with little labor and time costs.展开更多

Between 0.2 and 3.6 THz (6.6-120.0 cm-1 ), seven highly resolved spectral features, strong line-narrowing and a frequency blue-shift were observed with cooling. However, ractopamine hydrochloride, with some structural and pharmacological similarities to clenbuterol hydrochloride, showed no spectral features, indicating high sensitivity and strong specificity of THz-TDS. These results could be used for the rapid and nondestructive CH residual detection in food safety control.展开更多
