The characteristic absorption bands in the IR spectra of sunflower oil phospholipids were studied under various temperature regimes of degreasing. The most active chemical centers in the phospholipid molecule are ethylene bonds (isolated and conjugated), amino groups, phosphate groups, methylene groups, especially in the α-position to the double bond, and hydroxyl groups. The activity of P-O-groups and NH-groups increases at temperatures close to 800C. The above information confirmed that the degreasing of the phosphatide concentrate in the temperature range of 50–700C does not inactivate phospholipids. However, the degreasing rate of the phosphatide concentrate in this range already become high. Lutsenko М.

The foundation of contemporary society is agriculture, which is a significant part of human civilisation. Reduced arable land, climate change, water scarcity, and widespread population and labour migration from rural to urban areas have all slowed agricultural development rates. Therefore, enhancing agricultural output requires the implementation of novel strategies. Agriculture can play a crucial role in promoting economic growth because of its strong forward and backward links with the secondary (industrial) and tertiary (services) sectors. However, this industry has continued to face a number of difficulties, including rising input costs, climate change, temperature variations, a water deficit, and changes in precipitation patterns. Particularly in the areas of the world with the greatest food insecurity, the escalating effects of climate change could further reduce crop production. The paper presents the evolution of agriculture and the main crops grown at national and European level in the context of climate changes. TĂBĂRAȘU A.

The spent meal from the production of sunflower oil is a phosphatide concentrate that contains 50–60% of phospholipids (lecithin). We have developed a methodology for the defatting of phosphatide concentrate with isopropyl alcohol at an elevated temperature and low ratios of the phosphatide concentrate to the extractant, and subsequent identification of the components of food lecithin. Extraction at 60°C attains a relatively high yield of phospholipids; phosphatidylcholine, phosphatidylinositol, and phosphatidylethano- lamine predominate in the fractional composition of phospholipids; at the same time, the carbohydrate content is reduced.

The object of the study is the analytical values of lipids of milk thistle seeds of a modified composition, namely acid and peroxide values, as well as the induction period of lipids of chocolate mass with the addition of milk thistle seeds. The paper substantiates rational parameters of thistle seed processing for the inactivation of lipases and lipoxygenases. Approximate dependences of the acid and peroxide values of thistle seed lipids on the pH of the wetting solution and the wetting degree of seeds were obtained. This makes it possible to substantiate such rational processing parameters of thistle seeds that inhibit the accumulation of free fatty acids and primary oxidation products in seeds during storage. An increase in the induction period of the oxidation of the lipid component of the chocolate mass with the use of thistle seeds of a modified composition was proven, which is 2.5 times higher than the induction period of the chocolate mass sample with thistle seeds with a native enzyme complex. The research results make it possible to develop a technology of healthy chocolate mass using thistle seeds of a modified composition, the lipid component of such mass is stable to oxidation and hydrolysis. The data obtained in the work are explained by an increase in the ability to inactivate lipolytic and lipoxygenase enzymes of milk thistle at high humidity in an acidic environment under the influence of microwave radiation. The advantage of the obtained results is the possibility of not violating the integrity of thistle seeds during the inactivation of the enzyme complex, which allows extending the shelf life of this raw material. An applied aspect of using the scientific result is the possibility of expanding the range of healthy chocolate masses with the use of thistle seeds Stankevych S.
