APPLICATION OF LECITHIN IN BAKERY PRODUCTS MANUFACTURE

abstract 1161602021 issue 116 pp. 285 – 297 29.02.2016 ru 744
The article shows using plant phospholipids (lecithin) in the manufacture of bakery products. The article analyzes the patented ways of using phospholipids products (lecithin) in the production of bakery products in Russia and abroad. Patent search was conducted over the period from 1935 to 2015 on databases of patent offices of the United States, Japan and the European Patent Organisation. Conducted analysis led to the conclusion about the widespread use of phospholipids in bakery products. It was determined that generally there are used lecithins derived from sunflower, soybean and peanut oil, but the lecithins obtained from rapeseed oil production which are significant not only in Russia, but also abroad, are not used. Due to this, there were made conclusions about scientific and practical interest to study effectiveness of lecithin derived from rapeseed oil, to improve the quality, nutritional value and longer preservation of freshness of bakery products

COMPARATIVE ASSESSMENT OF NUCLEAR MAGNETIC RELAXATION CHARACTERISTICS OF SUNFLOWER AND RAPESEED LECITHIN

abstract 1131509034 issue 113 pp. 467 – 479 30.11.2015 ru 1001
The article presents a comparative assessment and peculiarities of nuclear magnetic relaxation characteristics of rapeseed and sunflower lecithin. It was established, that lecithin’s nuclear magnetic relaxation characteristics, namely, protons’ spin-spin relaxation time and amplitudes of nuclear magnetic relaxation signals of lecithin components, depend on content of oil’s fat acids and phospholipids, contained in the lecithin. Comparative assessment of protons’ spin-spin relaxation time of rapeseed and sunflower lecithin components showed, that for their identification protons’ spin-spin relaxation time of the lecithin’ first component at 40°C and 60°C temperature, when differences in values of protons’ spin-spin relaxation time of the sunflower and rapeseed lecithin’ first component are most obvious, should be used as an analytical parameter. Comparative assessment of amplitudes of proton’s NMR signals of sunflower and rapeseed lecithin components showed, that relations, established earlier for sunflower lecithin between mass share of phospholipids (substances insoluble in acetone) and the sum of amplitudes of proton’s NMR signals of the third and fourth components, cannot be applied to rapeseed lecithin; that is for the development of an express method for determination of mass share of substances insoluble in acetone (phospholipids) in rapeseed lecithin, it is necessary to carry out additional research with the purpose of clarifying the mentioned relations

DEVELOPMENT OF ECOLOGICALLY SAFE EXPRESS-METHOD FOR QUALITY EVALUATION OF SOYBEAN LECITHINS

abstract 1211607037 issue 121 pp. 698 – 707 30.09.2016 ru 576
The article presents data, on the basis of which we have concluded that the oil and phospholipids contained in soy lecithins, the degree of unsaturation of fatty acids differ significantly from oil and phospholipids contained in sunflower lecithins, with differences in the degree of unsaturation of fatty acids of oil and phospholipids contained in sunflower and soy lecithins, leads to differences in the content of resonating protons, and, consequently, the level of amplitude values of NMR signals of protons of the investigated lecithins. It is established that the values of the amplitudes of the NMR signals of protons of each of the four components of sunflower lecithins differ from the values of the amplitudes of the NMR signals of protons the component of soy lecithins, which confirms the differences in the composition and content of fatty acids lecithins studied. Considering quantitative characteristic of mass fraction of substances insoluble in acetone, i.e. phospholipids, is the sum of the amplitudes of the NMR signals of protons of the third (A3) and fourth (A4) component, was built the graphical dependence of the mass fraction of substances insoluble in acetone, from the value of (A3+A4)/ASIS, % which is described by the equation (correlation coefficient R2 =0,9911) of the following form: y=0,8177x +2.52. Based on these data, we have developed a rapid method of determining the mass fraction of substances insoluble in acetone, soy lecithin, eliminating the use of toxic organic solvents, is environmentally safe, which is protected by RF patent for the invention
