Chemistry of deep-fat frying oils.
Deep-fat frying produces desirable or undesirable flavor compounds and changes the flavor stability and quality of the oil by hydrolysis, oxidation, and polymerization. Tocopherols, essential amino acids, and fatty acids in foods are degraded during deep-fat frying. The reactions in deep-fat frying depend on factors such as replenishment of fresh oil, frying conditions, original quality of fryi...
متن کاملEffect of Deep-fat Frying on Chemical Properties of Edible Vegetable Oils Used by Senegalese Households
Deep-fat frying performed at high temperatures under atmospheric pressure is a common method of preparing dishes in Senegalese culinary practices. This operation can lead to deterioration of physical, chemical, nutritional and sensory properties of oil, which affects its frying performance. It also results in the production of volatile products such as aldehydes and non volatile fraction which ...
متن کاملEffect of Deep-Fat Frying on Phytosterol Content in Oils with Differing Fatty Acid Composition
The objective of this study was to determine the fate of phytosterols in vegetable oils with varying fatty acid composition used for frying. High oleic sunflower (HOSun), corn (Corn), hydrogenated soybean (HSBO), expeller pressed soybean (ESBO), and expeller pressed lowlinolenic acid soybean oil (ELLSBO) were used for frying potato chips in a pilot plant-scale continuous fryer. The same oils, a...
متن کاملStudies on the Deterioration of Frying Oils in Continuous Water-Spraying and Heating System. IX. Frying Quality of Oils Used for Frying in Japan
Physical and chemical changes were compared with soybean oil, corn oil, cottonseed oil , rice oil, rapeseed oil, lard, palm oil and coconut oil in continuous water spraying and heating system (Table -1 , Fig,-1•`4). Thermal oxidative changes such as viscosity increasing ratio, carbonyl and iodine value , showed close relation with the initial iodine value of these oils. However, in coconut oil ...
متن کاملOil absorption reduction of eggplant slices during deep fat frying by applying osmotic dehydration pretreatment
Background and Objectives: A fairly large amount of oil is absorbed to the food during deep frying. The aim of this study was to reduce the oil absorption of eggplant slices during frying by using osmotic dehydration pretreatment. Materials and Methods: Using maltodextrin (0, 20, 40% w/v) and sodium chloride (salt, 0, 10, 20% w/v), the effect of osmotic dehydration on different properties of e...
