Fat has an important role in creating texture, color and viscosity; but, it might be a source of many diseases in human. Mayonnaise is one of the most widely used sauces that contains fat in its formulation. There is an increase demand in reduction of the amount of fat in the diet or use of unsaturated fat. In the present study, mayonnaise samples containing various amounts of sesame oil were p...

Fish oils have many dietary benefits, but due to their strong odors and rapid deterioration, their application in food formulations is limited. For these reasons, nano-liposome was used to nano-encapsulate fish oil in this study and encapsulated fish oil was utilized in fortifying yogurt. Physicochemical properties of produced yogurt including pH, acidity, syneresis, fatty acid composition, per...

Due to the high antioxidant activity of oak fruits, the partial substitution effects of wheat flour (WF) or corn flour (CF) with oak flour (OF) have been investigated. WF or CF was replaced by OF at levels of 0%, 15%, 30%, and 45% in the biscuit formulations to prevent the spontaneous oxidation of lipids, and the characteristics, including peroxide value, antioxidant activity, and sensory prope...

The objective of current study was to investigate the effects of whey protein coating on the quality of common kilka during frozen storage period. For this study, common kilka was coated with 12% whey protein concentration. Also, non- coated kilka was used as a control sample. Coated and non-coated samples were then stored at -18 oC for six months. Bacterial, chemical and sensory properties of ...

AIM To measure the time course hydrogen peroxide penetration into the pulp cavity and evaluate short-term tooth color changes after bleaching. MATERIALS AND METHODS Twenty extracted human canines were sectioned, pulp tissue removed and the cavity enlarged. Teeth were painted with nail varnish to leave a 6-mm diameter circle on the buccal surface. Baseline color was measured spectrophotometric...

today the nutritional value of the meals, including snacks has increased because of consumer demand for healthy food. so the aim of this study was to examine the effect of adding stabilized wheat germ on levels of 0, 3, 6, 9, 12 and 15% (based on flour weight) on the quantity and quality of the un-extruded snacks. in order to measure the color values the image processing technique and image j s...

The effect of aqueous solutions of ascorbic acid (AA) on the rancidity development in Cobia (Rachycentron canadum) fillets during frozen storage was studied. Cobia fillets were treated with ascorbic acid (AA 0.25% and AA 0.5%) then stored at -18°C up to 6 months. Rancidity development was measured by several biochemical indices including free fatty acids (FFA), peroxide value (PV), and thiobarb...

The aim of study was to explore the dry distilled rose petals extract (DDRPE) addition Bulgarian lukanka type fermented sausages with half-reduced nitrate content. There studied antioxidative effect DDRPE in filling mass on color characteristics, pH, acid value (AV), peroxide (POV), TBARS and sensory characteristics. Four samples: C100 - 0.500 g/kg without DDRPE, C50 0.250 R1 1.140 R2 2.280 wer...
