THE METHODS OF ASSESSING THE QUALITY AND IDENTIFICATION OF LIPIDCONTAINING PLANT RAW MATERIALS AND PRODUCTS OF ITS PROCESSING WITH THE USE OF THE PULSE METHOD OF NUCLEAR MAGNETIC RESONANCE

abstract 1301706050 issue 130 pp. 727 – 738 30.06.2017 ru 651
The article provides an overview of Express-methods of quality evaluation and identification of lipidcontaining plant raw materials (oil seeds) and its processed products (oil cakes, oilseed meals, vegetable oils, lecithins) using pulse method of nuclear magnetic resonance. Development of express methods of quality evaluation and identification of lipid-containing plant raw materials and products of its processing is a priority, as these methods are environmentally safe and also allow us to regulate technological conditions of refining processes, are characterized by low error of determination, i.e., high precision, and, in some cases, it is only possible to use because of its non-destructive effects on the analyzed sample. Currently, we can distinguish the following main directions of quality evaluation and identification of lipid-containing plant raw materials and products of its processing on the basis of the pulse method of nuclear magnetic resonance: assessment of quality and identification of oilseeds (sunflower, canola, flax, soybeans); evaluation of quality of products of processing of oil raw materials (cake and meal); the quality evaluation and identification of vegetable oils; assessment of the quality of the lecithins obtained from vegetable oils. The methods of quality evaluation and identification of lipid-containing plant raw materials and its products are patented and have several advantages: short time (5 minutes) spent on the implementation of the single analysis; eliminates the use of toxic chemicals; does not require special training of laboratory personnel; non-destructive character, which is especially important for oilseeds from the point of view of breeding work. On the basis of the conducted survey we can conclude that the pulse method of nuclear magnetic resonance has found wide application for assessment of quality and identification of lipidcontaining plant raw materials and products of its processing, through rapid capabilities, high accuracy and ease of analysis
