world consumption of butter has declined over the last decades partly due to its physical limitations and partly due to its poor nutritionalproperties. in this study, the effect of hazelnut addition on the properties of butter, was evaluated taking into account that hazelnut is a source of unsaturated fatty acids and antioxidants. powdered hazelnut was added to butter at 3 levels (10, 20 and 30...

Nutritional value of freshwater mesozooplankton, fatty acid (FA) and amino acid (AA) compositions were determined in the middle of each season for a one-year period from May 2009 to February 2010 in Hanna Dam Lake, Isfahan, Iran. FA and AA composition significantly (P < 0.05) varied in relation to the seasonal changes of water quality, phytoplankton and zooplankton community. The content of sat...

dietary fatty acids play a critical role in modulation of airway inflammation in asthma. this study was conducted to compare dietary intakes of essential fatty acids and serum levels of inflammatory factors in asthmatic and healthy adults, and to examine the potential relationship between inflammatory markers and dietary fatty acids. in this case-control study, 47 asthmatic patients (26 males a...

The hexane extract of the flowers of Rheum ribes L. which was collected from north-western Iran,was obtained by Soxhlet apparatus and the essential oil composition was obtained by hydro distillationand analyzed by using GC-GC/MS. The extract from the flowers was characterized by a high amountof unsaturated fatty acids (UFA) (66.0%) and some of long chain hydrocarbon compounds. The maincomponent...
