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 کاملChanges in food caused by deep fat frying--a review.
Deep-fat frying is widely used in food industries because of its low cost and high demand, since it produces convenient food of high acceptability. The process is based on the oil-food interaction at high temperatures, which cooks and dehydrates the food, leading to physical and chemical changes, such as starch gelatinization, protein denaturation, flavoring and color production via Maillard re...
متن کاملComparison between traditional deep-fat frying and air-frying for production of healthy fried potato strips
The objectives of this work evaluate air-frying process as a new technique for frying process. The potato strips were fried in both air-frying machines (Tefal Actifry) at 180oC±5oC for 40 min and traditional frying process at 180oC for 40 min, 6 min/batch. After frying process, the moisture and oil uptake were determined. Changes in some physico-chemical properties of oil extracted from fried p...
متن کاملOil Absorption during Deep-fat Frying: Mechanisms and Important Factors
Deep-fat frying is a rapid and low cost process widely used to prepare tasty food. During this cooking process, oil is used both as the heating medium and as an ingredient producing calorific products. Nutrition has become a major health issue, especially in developed countries where increasing obesity is a problem, particularly among children. Many food research projects involving snack food i...
متن کاملColor Changes Kinetics and Heat Transfer during Deep Fat Frying of Garlic Slice
Heat and mass transfer phenomena that take place during frying cause physicochemical changes, which affect the colour and surface of the fried products. The effect of frying temperature on the colour changes and heat transfer during deep fat frying of garlic has been investigated. The colour scale parameters redness (a*), yellowness (b*) and lightness (L*), and color change intensity (∆E) were ...
