In this study nine new varieties of sunflower seeds were obtained and subjected to oil extraction using soxhlet apparatus. The extracted oil was analyzed for fatty acid composition and phosphorus content to measure the phospholipid concentration. The results indicated that Armavirski variety had the highest oil content. The fatty acid composition of the extracted oils indicated that Armavirski ...

The proximate composition of seeds and main physicochemical properties and thermal stability of oil extracted from Lannea microcarpa seeds were evaluated. The percentage composition of the seeds was: ash (3.11%), crude oil (64.90%), protein (21.14%), total carbohydrate (10.85%) and moisture (3.24%). Physicochemical properties of the oil were: refractive index, 1.473; melting point, 22.60°C; sap...

  Background: Frying is one of the popular cooking methods for the preparation of food especially meat products. However, this process has some adverse effects, such as lipid oxidation that results in deterioration and rancidity of food during preparation and storage. Malondialdehyde (MDA) as a secondary product of oxidation is commonly used as an index of rancidity in food products. However...

Background: Oils and fats are among the important constituents of foods. Lipid oxidation can cause changes in taste, flavor, smell, color, texture, and nutritional value of the foods. Deep-fat frying (temperatures of 150 to 200 °C) leads to a series of chemical and physical reactions, so that the oil is oxidized, polymerized, and hydrolyzed. Methods: In a current descriptive cross-sectional stu...

bezhi (or beji) is a special sweet and fried cookie which is produced traditionally in west region of iran. in this study, the effect of different temperature levels (150, 165 and 180°c) and frying time (1 to 8 min) on physicochemical properties of bezhi was investigated. the obtained results showed that increasing frying time up to the first 3 minutes causes a significant increase in sample vo...

Increase in organic waste generation, dwindling nature of global oil reserves coupled with environmental challenges caused by waste oil disposal and burning of fossil fuels necessitated the need for alternative energy resources. Waste cooking oil obtained from the frying fish outlet was analyzed for its physicochemical properties using ASTM D-975 methods. Acid and Iodine values of the oil were ...

Several issues, ranging from sustainability to health, may interest the consumers in the corn content of their food. However, because restaurants are excluded from the Nutrition Labeling and Education Act of 1990, national chain restaurants provide nonspecific ingredient information and small businesses supply none. We measured the carbon isotope composition of fry oil in French fries purchased...

introduction: texture is one of the most important attribute in foods and is always issues for the manufacturing of fried products, because texture plays a crucial role in consumer acceptance and the perceived quality of foods. prediction of changes in texture during frying can be helpful in process control. structurally, this quality parameter in fried potato strip made from the formation of a...
