Fats and oils as oleochemical raw materials *
Vegetable oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a corresp...
متن کاملAutoxidation of Fats and Oils
Products that contain fats and oils turn rancid and deteriorate in other ways when they arc exposed to air. The action^ known as autoxidation, imparts disagreeable flavors and odors to fats and foods containing them. For a long time baffled investigators spent a vast amount of effort trying to find ways to prevent autoxidation. Specifically, the basic problem was the mechanism of autoxidation—h...
متن کاملTreatment of waste oil-in-water emulsions from a copper metalworking industry by vacuum evaporation: effect of operating conditions
The efficiency of treatment of synthetic and semi-synthetic waste oil-in-water (O/W) emulsions by vacuum evaporation is evaluated. A previous destabilisation/centrifugation stage increases the quality of the final aqueous effluent. However, proper selection of a coagulant salt or flocculant is required. A comparison of laboratory-scale evaporation results and those obtained in an industrial eva...
متن کاملOptimization of Biodiesel Production Process from Restaurant Waste Frying Oils in the Presence of Homogeneous Catalyst
Background and Objective: Because of the importance of the role of energy in the world and nonrenewability of fossil fuels and caused environmental issues by these fuels in recent years, many studies have been conducted to find an appropriate alternative to fossil fuels in different countries of the world. Biofuels such as (biodiesel and bioethanol) have been introduced as one of the most desir...
متن کاملPolymorphism in Fats and Oils
Triacylglycerols (TAGs) are the major components of fats and oils and biologically important organic molecules along with proteins and carbohydrates. In industrial applications, TAGs are the main components in cream, margarine, and confectionery fats in foods and as matrix materials in pharmaceuticals and cosmetics. The physical behavior of TAGs influences the physical properties of fat-based p...
