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 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 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 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 کاملCarbonyl compounds vaporize from oil with steam during deep-frying.
Used frying oil recovered from food manufacturing companies in Japan and recycled often shows lower carbonyl (COV) and peroxide values (POV) than oil simply heated at 180 degrees C for 20 h does. In this study the reasons for the low COV of oil used for deep-frying were investigated by employing model experiments and actual commercial frying. The results suggested that in actual frying, the fac...
