Changes of selected antioxidants content and activity in broad bean seeds upon sterilization process and storage of cans were investigated in the study. Loss of total nitrogen, its solubility and non-protein nitrogen content was observed as well as loss of total polyphenols content and their antioxidatively important group – condensed tannins. Main changes in protein fractions were observed on electrophoretic patterns in low molecular weight range, however a gain of high molecular weight polymer (500 kDa) participation was shown by Size-Exclusion HPLC. Phenolic compounds extracted with 70% acetone exhibited much higher antiradical activity then nitrogen compounds extracted with water. A decrease of antioxidant activity of the extracts and its appearance in drain was confirmed in most cases after processing and storage.
Systematic increase of demand for wooden biomass and fuels generated from it is the result of the need to fulfill European Union obligations. For those sawmills which very often operate on the verge of profitability it creates a chance for improving their efficiency. Those having a sufficient amount of raw material at their disposal should consider launching production of wooden briquettes, as such initiative does not require any significant investment and may be complementary to company primary activities. Profitability of such venture depends on numerous variables. The aim of this article was to determine the value of sawmill residue when processed further into briquettes taking into account the impact of various factors. The research took account of: material intensity ratio depending on the material used, sales price per unit of final product, the entrepreneur’s target margin, briquettes production cost as well as the cost of transport in case of those enterprises which do not possess their own raw material.
The functional food development is one of the most interesting fi elds of the food industry. The knowledge of the effects of processing is essential in order to optimize the conditions and to obtain functional foods rich in bioactive compounds. Many functional buckwheat derived bakery and non-bakery products have been put into production including buckwheat enhanced breads, biscuits, snacks, noodles, tea, tarhana, sprouts, and fi nally buckwheat honey. This article reviews the studies carried out in the past few years in relation to the effects of processing on bioactive compounds in buckwheat derived bakery and non-bakery products, and on their overall nutritional value and consumer acceptance. Finally, the future trends in buckwheat processing are addressed.

Rapeseed growing for energy purposes in Ukraine

63%
The article presents the results of research of a solution to the problem of reducing energy dependency and replacing traditional sources of fuel production to agricultural ones. Nowadays it is very important not only for Ukraine but for most countries of the world. That is why the rapeseed as a row material for biodiesel fuel is a practical alternative being renewable and very productive. The analysis of the current situation of rapeseed growing, its processing and possible trends for the future industry are shown. Factors that can contribute to creating the conditions necessary to support these trends are grounded. Calculation results of rapeseed growing efficiency for bio-energy purposes in agricultural enterprises are displayed. It is proved that the rapeseed growing has the highest efficiency in the variant of its processing for biodiesel.
The paper is focused on analysis of economic situation on particular processing stages within the wheat commodity vertical and on its comparison with food processing industry. The Spider Analysis method is used for evaluation. The analysis has shown enhancement of milling industry position and worsening of bakery industry position in the last time and confirmed low market power of both processing stages. Vertical integration or coordination within the commodity chain is believed to become a necessity to maintain on the market as well as to be competitive.
Our experiment was carried out in experimental plots of the Vegetable Experimental Station of the Agricultural University in Mydlniki near Kraków, Poland in 2008-10. The year 2008 was characterized by the driest season of all three years, whereas in the other years of the study the vegetation season seemed moderately humid. Based on the analyses of regression, we found a significant influence of pluvial and thermal conditions on the fruit quality features of tomatoes. A directly proportional relationship between the hydrothermal index (K) and the number of seed chambers, dry matter, and content of lycopene, magnesium, and calcium of the tomato fruit was observed. However, the relationship between the hydrothermal index (K) and fruit weight, potassium content, and total acidity turned out to be inversely proportional. The impact of the hydrothermal conditions on the thickness of the pericarp, the shape coefficient, phosphorus; L-ascorbic acid content, and the reducing sugars of the fruits was not observed. The value distribution of the tested tomato features in all of the years of the experiment points to the different sensitivities of individual tomato cultivars to thermal and precipitation conditions. The aim of this study was to determine the influence of hydrothermal conditions represented by the hydrothermal index (K) on the morphological features of tomato fruits and their chemical composition.
