This work research object was fat systems interesterification biotechnology using the Lipozyme TL IM immobilized enzyme preparation. The problem of enzyme preparation activation by moistening with sodium bicarbonate aqueous solution with 7.4 ... 7.7 (3 % wt.) pH was solved in the work. The obtained results made it possible to minimize the interesterification process duration with high-quality product obtaining. The proposed enzyme preparation processing made it possible to reduce the duration of the biointeresterification process in a model fat mixture (palm stearin, coconut and soybean oils in a ratio of 1:1:1, respectively) to 3.5...3.7 hours. The product with high quality indicators, namely up to 0.26 mg KOH/g acid number, up to 0.60 mmol ½ O/kg peroxide number and 1.70 c.u. anisidine number, was obtained as a result. The obtained data can be explained by a fact that effective biocatalysis with lipolytic enzymes as the protein molecules requires the existence of two phases – lipid and water. This fact was provided by the activation parameters justified in the study. The obtained results feature was possibility of enzyme preparation activation, which is not provided under industrial conditions due to the threat of raw materials and finished products hydrolytic processes, which leads to the finished product quality deterioration. The research results made it possible to minimize hydrolytic processes in fat system during interesterification with simultaneous process efficiency increase. From a practical point of view, the discovered activation mechanism made it possible to adjust the enzyme preparation processing conditions in fat systems interesterification technology. The applied aspect of scientific result using was the possibility of improving the typical technological process of fat interesterification
The health condition of European ash (Fraxinus excelsior) stands in Ukraine has become worse since 2006. Firstly, in 2011 an alien invasive pathogenic fungus Hymenoscyphus fraxineus was identified in the eastern part of the country and, subsequently, its presence was confirmed in the western and central parts. The aims of our research were to evaluate the health of ash trees and identify the main causes of ash decline in different regions of Ukraine with emphasis on ash dieback and its association with collar rots. Results showed that since 2013 the number of trees with ash dieback symptoms has been gradually increasing, reaching up to 92 % in 2018. Total mortality due to ash dieback was up to 9 % in 2018. Disease intensity remains high in northern and central Ukraine comparing with the east. Branch dieback, collar rots, epicormic shoots and bacterial disease of ash occurred more often in the eastern region, some symptoms were observed simultaneously. Ash bark beetle galleries, as well as foliage browsing insects, were found mostly in weakened and/or dying trees. It was indicated that collar rots significantly increase the mortality of ash trees. Armillaria spp. fungi were found to be frequently associated with ash dieback on living stems and fallen trees in 2017, causing high rates of mortality in the northern and central regions. For further ash conservation and breeding programmes, resistant trees in severely damaged regions should be selected to preserve genetic diversity in ash populations. Keywords: Fraxinus excelsior, ash dieback, collar rot, bacterial disease, epicormic shoots, Hymenoscyphus fraxineus, Armillaria spp.
