This study was aimed at determining lipid content, fatty acid composition and trans isomers content in fat extracted from cereals and cereal bars. Cereals and cereal bars were analyzed by gas chromatography. Analyses showed that they were characterized by a diversified content of fat and composition of particular groups of fatty acids (saturated SFA, monounsaturated MUFA and polyunsaturated PUFA)...
Background. Natural mineral waters may be an essential source of calcium, magnesium and other minerals. In bottled waters, minerals occur in an ionized form which is very well digestible. However, the concentration of minerals in underground waters (which constitute the material for the production of bottled waters) varies. In view of the above, the type of water consumed is essential. Objective....
Background. Natural mineral waters are purchased and consumed according to consumer preferences and possible recommendations. The choice of appropriate water should take into account not only the general level of mineralization but also the content of individual components, including electrolytes such as sodium and potassium. Sodium is necessary to ensure the proper physiological functions of the...
Celem badań była analiza właściwości reologicznych, tekstury oraz barwy ricott dostępnych na polskim rynku. Materiał badawczy stanowiły ricotty niedojrzewające pochodzące od czterech producentów, zakupione w handlu detalicznym na terenie Olsztyna. W badanych ricottach oznaczono zawartość suchej masy, białka ogółem, tłuszczu, laktozy, popiołu oraz zmierzono kwasowość czynną. Do badań reologicznych...
Celem badań była ocena zawartości wybranych składników mineralnych w suszonej serwatce kwasowej uzyskanej podczas produkcji twarogu. W serwatce kwasowej w proszku oznaczono zawartość wody, białka, laktozy, tłuszczu, popiołu oraz kwasu mlekowego. Celem oznaczenia składników mineralnych próbki badanej serwatki mineralizowano na mokro. Ca, Mg, Zn, Fe, Mn i Cu oznaczano techniką płomieniowej spektrometrii...
Celem pracy było określenie zawartości wybranych makroelementów i mikroelementów w kazeinie kwasowej i kazeinianach. Materiał badawczy stanowiła kazeina kwasowa otrzymana metodą tradycyjną oraz kazeiniany: sodu, wapnia i sodowo-wapniowy otrzymane metodą ekstruzji. Badane preparaty białkowe pochodziły z produkcji przemysłowej. W kazeinie kwasowej i kazeinianach oznaczono zawartość wody, związków mineralnych...
The objective of this study was to determine the content of selected macroelements and microelements in acid tvorogs with a different fat content. The analyzed material consisted of skim (0% fat), medium-fat (4% fat) and full-fat (8% fat) acid set tvorogs supplied by the same manufacturer. Dry matter content and total ash content was determined in the analyzed cheeses. Tvorog samples were subjected...
