The task of the research was to study the chemical composition of sea buckthorn and raspberry marc as well as of high milling wheat bread with berry marc. Wheat bread, i.e. the control sample and the bread samples with 3%, 5% and 7% (from the flour mass) of raspberry and sea buckthorn marc, was baked in the experimental bakery. The content of sugar, fat, protein, fibre and titratable acids was determined by using standard methods. The content of vitamin E, carotene, pectin and phenol compounds was determined by using spectrophotometric method. The obtained results prove that sea buckthorn and raspberry marc have fibre, fat, sugar acids, carotene, phenol compounds, vitamin E, and pectin. The content of fibre and carotene increased in wheat bread samples when raspberry and sea buckthorn marc was added. Depending on the amount of marc added to the bread, the changes in the content of fat, sugar, and carotene in wheat bread samples were studied. The wheat bread with raspberry and sea buckthorn marc contained vitamin E and phenol compounds.

The possibility to use cranberry juice for acidification of water in the process of beer making instead of traditionally used acidifiers is researched in this work. The output of mail extract received from cranberry juice with acidity regulator is 21.84%. Physicochemical parameters of mash and beer have been defined. The developed method is recommendable for beer production at small enterprises and in home environment.

The main pine natural woodland habitats (woodland key habitats -WKH) and the importance of their management and monitoring have been described in this paper. The ecological importance of lichen epiphytes in forest ecosystem has been analysed. The lichenoflora and its percental cover features have been described. The exposition of lichen species depending on the cardinal points has been analysed. The paper presents the characteristics of ecological indicators of lichen in the landscape features. The lichenoindicative evaluation and comparison of pine WKH have been carried out.

The manufacture and export of pallets is one of the largest sectors of the wood industry. For the manufacturing of pallets mainly softwood - spruce (Picea abies L. Karst.) and pine (Pinus sylvestris L.) wood - materials are used. The price of those materials is increasing. It could be better for the production of pallets if the manufacturers could use hardwood - alder (Alnus incana L. Moench) and aspen (Populus tremula L.) wood materials. The reasons for that could be that these materials are not so expensive and that softwood materials could be used more in the wood industry where it is more necessary. But at that point more information about the physical and mechanical properties of hardwood materials needed. Basing on the previous research on quality and mechanical properties of softwood and hardwood and on the present research work the practical and theoretical values of deflection and strength of pallets have been assessed. The research enables us to optimize the preparation for pallet production. The aim of the research is to find out the strength of the pallets without destroying.
