background & aim:   changes in lifestyle, decrease in physical exercise along with incidence of obesity, hypertension and cardiovascular diseases indicate a need for low calorie formulations. the sweetness of stevia, a natural sweetener, is estimated to be 300 times as much as that of sugar. extraction of stevia leaves is considered a promoter of calorie balance and a beneficial part of a h...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...

seuyoty was one of the most celebrated medieval authors in arabic literature and during a literary period known as mamlooki era. although anecdote (magama) is a literary type which is written like a story and is based on the beggarliness and trickery of the first character of the story, seuyoty’s anecdotes (maqaamas) are different from the anecdotes of his predecessors. seuyoty’s magamas are no...

food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they demand ...

despite the numerous health effects of the dietary fibers, the amount of the fiber in the diet is generally lower than the recommended value. therefore, increasing the fiber content of the foods particularly those of high consumption can compensate for the shortage of the fiber in the diet. however, it seems a difficult task since increasing the fiber content can have adverse effects on product...

Vacuum impregnation is a non-destructive method of introducing a solution with a specific composition to the porous matrices of fruit and vegetables. Mass transfer in this process is a result of mechanically induced differences in pressure. Vacuum impregnation makes it possible to fill large volumes of intercellular spaces in tissues of fruit and vegetables, thus modifying physico-chemical prop...

F OOD iron absorption studies in man, using radioiron incorporated biologically into the food, have shown that iron from vegetable foods is poorly absorbed,13 especially from staples, such as corn and black beans, which are consumed in large amounts by individuals belonging to the low socioeconomic levels in Latin American countries. Layrisse, MartInez-Torres and Roche’ have observed that iron ...
