The study investigated the dietary impact of 18:3n-3 vs. 18:2n-6 on fatty acid- and micronutrient concentration of beef muscle and the extent of diet- and processing-induced changes of lipid- and micronutrient concentrations of beef products made thereof (German Corned beef (GCB), tea sausage spread (TSS), scalded sausage (SS)). Beef and beef products were obtained from German Holstein bulls wh...

The objective of this study was to compare the influence of: genotype, environmental conditions and processing methods on levels of tocochromanols carotenoids and chlorophyll after maturation and harvesting in flaxseed oil from four varieties (Altess, Biltstar, Niagara and Oliwin). Oils were produced by cold pressing of dry seeds and seeds that were heated for 30 min at 60 °C. Temperature, suns...

The benefit of rice bran to human health is already wellknown. It is a rich source of fiber, vitamin B1, tocoferol and γ-oryzanol. Unfortunately, freshly milled rice bran has a short shelf life because of its high triaclyglycerol content, which tends to decompose into free fatty acids (FFA). The last are responsible for off flavor development during rice bran storage. In this research, hot scre...

Development of marker-free transgenic plants is a technical alternative for avoiding concerns about the safety of selectable marker genes used in genetically modified (GM) crops. Here, we describe the construction of a spontaneous self-excision binary vector using an oxidative stress-inducible modified FLP/FRT system and its successful application to produce marker-free transgenic rice plants w...

In the present studies, we focused on substrate specificity of tocopherol cyclase, the key enzyme in the biosynthesis of the tocopherols and plastochromanol-8, the main plant lipid antioxidants, with special emphasis on the preference for tocopherols and plastochromanol-8 precursors, taking advantage of the recombinant enzyme originating from Arabidopsis thaliana and isolated plastoglobules, th...

This study was conducted to investigate and compare the fatty acids and tocopherols of lipid extracted from marine microalgae, Nannochloropsis oculata (NO) and Tetraselmis suecica (TS) using solvent extraction and supercritical fluid extraction (SFE). Fatty acids and tocopherols were determined in the extracted lipid as functions of the temperature (40, 80oC) and pressure (3000, 5000, 7000, 900...

Micronutrient fortified flour (MFF), supplementary food rations and micronutrient (MN) supplements may prevent deficiencies among pregnant women. Objectives of cross-sectional surveys in 2004 (n = 533) and 2006 (n = 515) were to assess the impact of new food rations (flour, oil) and supplements on MN status by trimester of pregnancy in the Maela refugee camp. Hemoglobin, iron status, zinc, reti...

A new sample treatment methodology was developed for the simultaneous determination of oleic, linoleic, palmitic and stearic fatty acids (FA), α-, β-, γ- δ-tocopherol homologues in peanut samples. Usually, these compounds is carried out after oil extraction with an organic solvent at boiling temperatures solvent. The innovative analytical this work performed a 20 mL vial which FA tocopherols we...
