Dietary fibres (DF) have been isolated from rapeseed and peas, separated into different fractions and investigated for their content of associated non-carbohydrate compounds, especially proteins by UV-spectroscopy, nitrogen determination, isoelectric focusing, and rocket Immunoelectrophoresis. The level of protein varied according to the plant origin of DF and among the different DF fractions (pectins,...
In the present work it was evaluated to what degree the selected fractions of dietary fibre, i.e. cellulose, lignin and high-methylated pectins with the metyla- tion degree of 56 or 73%, influence the determination of sodium nitrite added to in vitro gastric juice with the pH from 2.0 to 3.5. High-methylated pectin was the fraction of dietary fibre which was found to decrease the amount of sodium...
The nutritional habits of women and men employed in the budgetary and non-budgetary sectors were assessed for the Wielkopolska region Irrespective of the differences observed for both groups of workers, the examined food rations were not balanced regarding the proportions of energy from fats and carbohydrates, antioxidant vitamins, saturated fatty acids and dietary fibre. The differences in the intake...
The aim of this investigation was to determine the relationships between lead sorption and calcium desorption on black currant pomace fibre preparations and their compositions with apple pomace, as well as to assess the suitability of fibre composition as selective sorbents of metals (Pb, Ca) in certain foodstuffs. It was found that the investigated materials had a high dietary fibre content (>65%)...
Effects of enriching a non-modified diet of dyslipidaemic men and women with hull-less oats (Akt variety), contributing 10-15% to the diet's calorific content, on the levels of glucose, triacylglycerols, total cholesterol, HDL- and LDL-cholesterols, and fibrinogen were tested experimentally. The women eating the oat-enriched diet for 6 weeks were found to have reduced their triacylglycerol, total...
Five different extrudatcs were produced that were composed of ground oats, oat flour and corn groats. These substrates were used in different proportions: extrudates E1 and E5 did not contain corn groats but oats products only. The remaining extrudates (E2, E3, E4) contained corn groats and oats substrates in similar proportions. In the extrudates as well as in the mixtures of initial components the...
Rats of control group were fed a standard diet (LSM). One of the diets was supplemented with 1% cholesterol (LSM+CH), another one with 5% freeze-dried apple pulp (APP), and the last one with both, 1% cholesterol and 5% apple pulp. Dietary addition of apple pulp significantly increased calcium concentration in femur bone from 154.2±5.6 (LSM, LSM+CH) to 180.1±4.8 g/kg wet weight (APP, APP+CH), while...
The study concerned nine assortments of multi-cereal breakfast flakes. Tests were performed to determine the content of dry mass, crude ash, crude proteins, crude fat, and crude fibre. The fractional composition of dietary fibre was determined with the detergent method (NDF, ADF, HCEL, CEL, ADL) and with the enzymatic method (TDF, IDF, SDF). Also, determinations were made of the content of soluble...
The aim of the study was to assess the effect of varying amounts of potato fiber and bran preparation on the quality of finely comminuted thick wiener type sausages. In sausage batters 7.5% and 10% fine fat were successively replaced with rehydrated (1:5) fiber preparations. Proximate analyses were conducted to determine the basic chemical composition of sausages (contents of water, fat and protein)...
Bean seeds have a unique nutritive value as they deliver valuable proteins, saccharides, minerals and vitamins, and dietary fibre. Besides, they contain a wide range of bioactive compounds that cannot be considered as nutrients, however they exert physiological effects on humans. The purpose of the present review is to describe the main nutritional and antinutritional compounds of bean seeds as well...
The aim of these studies was to examine the effect of addition of four oat forms on the physical properties of wheat dough and quality of sponge‑fatty cakes. The research material consisted of wheat flour type 450 and the grain of two naked (Akt and Polar) and two husked (Dukat and Sprinter) oat varieties. The physicochemical analysis was performed on wheat flour and oat grains, which was followed...
The intake of food products containing prebiotics has a beneficial effect on the functioning of the gastrointestinal tract and may also contribute to increased mineral absorption from a diet. In the food industry prebiotics (inulins and maltodextrins) are also used because of their functional properties such as stabilizing emulsions. A study was undertaken to investigate the effect of inulin HPX and...
The objective of the study was to estimate the content of basic nutrients in the most popular assortments of wheat breakfast cereals. Determinations made for samples of the tested products covered the content of dry mass, total ash, total protein, and crude fat. Due to the role of dietary fibre as the main quality determinant of cereal products, the content of that component was tested with three...
