the aim of this study was to investigate the effect of ultrasound and drying pretreatments on apparent density as well as modeling apparent density during deep-fat frying of potato slices. ultrasound pretreatment was performed at 28 and 40 khz for 15 min and drying pretreatment were conducted at 80°c for 8 and 15 min. then, the frying process was done at 150, 170 and 190°c for 60, 120, 180 and ...

Background and Objectives: Canola oil is very low in saturated fatty acid (~8 %), which makes it suitable for application as dressing for salad. Canola oil is liquid, thus its application in the production of margarine and shortening is limited. The present study provides information about the effects of monoacylglycerols (MAG) as the structuring agent on physical, microstructure and rheologica...

background: studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (nafld). however, the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld are not clear enough. the aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on nafld prognos...

the effects of l-carnitine on growth performance and carcass composition in male broiler chicks, fed diet in which cp was reduced in a stepwise manner from 21 to 18% were investigated. ileal digestible quantities of all eaa were almost equal in the diets, with quantities nrc 1994 recommendations. one hundred forty four male commercial broilers were allotted to six groups, each with four replica...

Butter, margarine and butter oil are three products which consume daily by Iranian’scommunity. Detection of type and existence of synthetic antioxidants (SAs) quantities in the margarine, butter and butter oil samples is so important in point of view of the safety. For this purpose, peroxide value (PV), oxidative stability (OS), iodine value (IV), fatty acid analysis (FA), type and amount of SA...

Previously an experimental infection model was developed in which broiler chickens were inoculated with sporulated Eimeria acervulina oocysts at an age of 18 d. The infection resulted in adverse performance results and reduced nutrient digestion. In two new experiments with the infection model effects of diet adjustments on fat digestion were investigated. In the first experiment addition of 0....

A population-based, case-control study of prostate cancer in Utah was used to assess reported food-consumption patterns for the adolescent and adult years. Men reported eating eggs, whole milk, butter, white bread, cereals, and candy less frequently and red meat, fish, low-fat milk, cheese, yogurt, ice cream, margarine, fruits and vegetables, and whole-wheat bread more frequently as adults, ind...

Food photographs are widely used as instruments to estimate portion sizes of consumed foods. Several food atlases are available, all developed to be used in a specific context and for a given study population. Frequently, food photographs are adopted for use in other studies with a different context or another study population. In the present study, errors in portion size estimation of bread, m...

in this research, production possibility and shelf life of frying margarine had analyzed. in order, the test was done in factorial form and totally random method. tested factors were different kinds of margarine (counteractive effect between type of oil in oil phase (canola) and different moisture (16-8-4%) as the first factor and time of keeping margarine as the second factor. in this margarin...
