The purpose of this work was to characterize some physico-chemical properties of proteins in raw and stored Tibo faba beans. The storage caused that the faba bean proteins were partialy degraded and hydrolysed, which resulted in a decreased content of albumins, globulins, and amino acids in stored seeds. The nutritional value of proteins decreased due to loss of essential amino acids and lower susceptibility...
The effects of culture conditions (pH 4.0-5.0, 25-35°C, 48-96 h) on cell growth, lipid accumulation and lipid composition (fatty acids, mono-, di-, and triacylglycerols) are reported for Mortierella ramanniana var. angulispora IFO 8187 cultivated in shake flask in glucose medium. The highest yield of biomass (22.4 g/L), lipids (3.9 g/L) and y-C18:3 (178.1 mg/L or 8.8 mg/g dry cell weight) was observed...
The content of dry matter was statistically significantly higher in ecological potatoes (ECO). The difference was 1.3 g/100 g fresh mass. The content of nitrates in ECO tubers was 266.6 mg KNO3/kg fresh mass on average, being significantly lower in conventional (CONV) tubers, in which it was 838.7 mg KNO/kg fresh mass. The content of NaNO2 was higher in CONV potatoes, but the difference between CONV...
Using the method of food frequency questionnaire, energy intake and that of selected nutrients was studied in two groups of children with coeliac disease kept on gluten-free diet or on traditional diet containing gluten. The recommended dietary allowances for energy, basic nutrients, phosphorus, magnesium, potassium, vitamins A, E, C and B-vitamins (thiamin, riboflavin and niacin) were generally sufficiently...
The physico-chemical and functional properties were examined for sodium caseinate, calcium caseinate and sodium-calcium caseinate of new kind obtained by extrusion-cooking. The latter was found to be characterised by the most developed, porous microstructure and the highest values for water solubility, fat absorption capacity, and ability to stabilise the oil/water emulsion. Calcium caseinate showed...
The research was taken up in the aim of comparing daily food rations nutritional value for people snacking or not snacking from two age groups: youth (13-15 years old, 124 persons) and students (19-26 years old, 190 persons). Among all analysed sub-groups, there were people snacking or not snacking. Nutritional value of food consumed by young people in daily food rations (DFR) and snacking (S) was...
The aim of this study was to establish sensory and nutritionally acceptable enrichment level of low calories spreadable fats (soft margarine and mix of butter and vegetable oil) with omega-3 eicosapenta- and docosahexaenoic acids (EPA, DHA) by addition offish oil preparations (ROPUFA - 30% EPA, DHA and MARITEX - 10%), and evaluation of enriched spreads stability (sensory and chemical) during storage...
The effects of soil and its fertility on the mineral content of fodder and on quality, nutritional value and mineral composition of cow milk were studied. The samples of soil, the soil-originated fodder, and milks from cows fed the fodder were taken from 45 peasant farms. The soil was assayed for the type, firmness, pH value and macroelement resources. The fodder was assayed for the nutritional value...
The estimation of chemical composition and nutritive value of protein of lamb meat from the quadriceps muscle of the thingh (m. quadriceps femoris) was carried out in this studies. Meat proceeded from single ram lambs of Pomeranian breed (P), ile de france breed (IF) and their cross-breeds F1 (PIF), at the age of 50 days, eight heads from each group. Dry matter (W), total protein (B), total fat and...
