The aim of the study was to show the nutritional and health benefits implied by consumption of bread and pastry supplemented with linseed meal. Bread with 10 and 13% share of linseeds was characterised by higher amounts of protein, fat, dietary fibre, macro- and microelements in comparison to standard one. In the experiments on rats, a spectacular hypocholesteric effect of such bread was observed...
The aim of the present work was to determine the influence of kernel size on wheat grinding properties. The samples of kernel were divided into three fractions according to different thickness: small (2.0-2.5 mm), medium (2.7-2.9 mm) and large (3.1-3.5 mm). The results showed that the kernels size had an influence on bulk density, PSI hardness index and ash content. As kernel size increased, the bulk...
The study was conducted on 32 crossbred fatteners (Polish Landrace x Large White Polish) x (Duroc x Pietrain). Fatteners belonging to group S were fed the compound feed with a 6% supplement of soybean oil during the fattening period (30-100 kg) while fatteners assigned to group L were fed the same feed until they reached 70 kg of body weight. At this point, the soybean oil supplement was changed to...
Structured triacylglyccrols (sTAG), not so long ago called "lipids of the future", have become functional food available on the market In the nearest Iuturc, some iatty products designed for infant and children nutrition in the USA will contain increased concentrations of arachidonic (AA) and docosahexacnoic (DHA) acids. Many formulae and dietetic products containing triacylglyccrols with...
One of the main indices of the nutritional values of fruit and vegetable products as well as the correctness of the technological process is the content of vitamin C. The two routine (according to ISO) methods for the determination of vitamin C, the titrimetric and the spectrophotometry methods, currently in use in industrial Polish laboratories are often not sensitive enough or are time-consuming...
The objective of this part of the study was to determine biological value (BV) of pea protein for growing rats. Also, to compare the N-retention responses of the rats to supplementation of the pea protein with: (1) the same protein, (2) the mixture of essential and non-essential amino acids formulated to reproduce the pea protein, and (3) the mixture of essential amino acids only, formulated as above...
The trypsin inhibitory effect of phenolic extracts from different plant foodstuffs: two bean varieties, black and green tea and quince fruits as well as of standard phenolic compounds: ( + )catechin, (-)epicatechin, gallic acid and tannic acid, was investigated. Monomeric tannin precursors exhibited 1000-times lower activity in the trypsin inhibition than high-molecular tannic acid. All of the plant...
In a feed experiment carried out on 24 cross-breed fatteners [(Polish Large x Polish Landrace) x pietrain] randomly divided into two groups (12 animals in each, 6 gilts and 6 barrows), the fattening of feed mixtures with 3% corn oil and the addition of α-tocopherol acetate in the amount of 200 mg/kg of mixture for the experimental group were used. The addition of vitamin E to the diet caused a significant...
A study was conducted in order to identify and characterize the specific nutritional models of the student population. It included 190 male and 454 female students with a mean age of 20.7±1.68. The analyzed student food rations nutrient value was determined by the 24-hour recall method. The calculated energy and nutrient content in the food rations was reduced, and then compared with the nutrition...
The mathematical model describing the course of drying curve of single parsley root particles under conditions of natural convection was formulated on the basis of the general theory of heat and mass transfer laws. The course of the drying curve was described in two ways: using the linear model of the first drying period (without shrinkage) and then using the models of second drying period and the...
The texture and histology of selected muscles (m. longissimus dorsi, m. quadriceps femoris, m. biceps femoris, and m. semimembranosus) of piglets and wild boar juveniles were compared. The muscle texture was determined with the TPA test performed with an Instron 1140 apparatus. Structural elements (muscle fibre cross-section area, peri- and endomysium thickness, area of intramuscular fatty tissue)...
