Fats and oils as major dietary components are involved in the development of chronic diseases. In this paper the physiological relevance and some methodological aspects related to the determination of two enzymes enrolled in metabolism of fat – pancreatic lipase and arylesterase – are discussed. Pancreatic lipase has been extensively used to study the triacylglycerol fatty acid composition and ...

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...

The aim of this study was to investigate the effects of breading materials and two different frying oils on the fat up-take in the fish fillets during frying process. Breaded and non-breaded black pomfret (Parastromateus niger) fillets were fried in sunflower oil and palm olein. Fat content by Soxhelet method and scanning electron microscopy (SEM) was studied. Results from Soxhelet method showe...

Vegetable oils and fats have a big contribution in our diet as cooking or frying oil, salad oil or in food products formulation. They are important from nutritional and economical point of views. Their authenticity is a serious issue since old time. Some edible oils and fats such as olive oil, cocoa butter and milk fat are so expensive which makes tempting to adulterate them with other lower pr...

Abstract Headspace-gas-chromatography ion-mobility spectrometry (HS-GC-IMS) proved the diversity of volatile chlorinated compounds (VCCs) in frying oil this work. First, VCCs were obtained by headspace heating at 80 °C for 30 min. Then, those separated GC capillary column first dimension and IMS second dimension, respectively. And last, detected negative ion mode non-targeting. The study result...

Comparative frying studies on the processing of extruded product were conducted under intermittent and continuous frying conditions using two separate frying systems, i.e batch and pilot scale continuous fryers, respectively. Thermal resistance of palm olein were assessed for a total of 5 days of frying operation at 155°C - the unconventional frying temperature gave the product moisture content...

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...
