Mustard oil is used widely in food processing in many economically developing countries. Reuse of edible oils is very common in such countries. Although oils are inexpensive sources of fat and Vitamins, processing leaves a effect on processed food. Present study is so concerned with such type of common reuse of mustard oil in food processing and subsequent toxicological impact on selected rat t...

Biodiesel is usually produced by transesterification of vegetable oils or animal fats with chemical catalysts, especially in the presence of strong acidic or basic solutions, such as hydrochloric acid, sulphuric acid, sodium hydroxide, sodium methoxide and potassium hydroxide. Homogeneous alkali catalysts can convert triglycerides to their corresponding fatty acid methyl esters (FAMEs) with hig...

Many oils from plants are important components of our food chain and maintaining their oxidative stability (OS) is economically and nutritionally important. OS is dependent in part on antioxidant capacity (AC) arising from the electron donating ability of endogenous compounds in the oils. Attention has focused on the contribution to AC of phenolic compounds in oils as many have bioactivities in...

This study investigates the concentration levels of selected priority PAHs; Phenanthrene (Phe), benzo[a] pyrene (BaP) and benzo[k] fluoranthene (BkF) in three brands of refined edible seed oils (30 samples). The samples were hydrolyzed in methanolic potassium hydroxide, and the PAH extracted in n-hexane according to standard methods. The PAH extracts were cleaned using solid phase extraction (S...

In this work we report on a new, rapid and simple voltammetric method to determine the total antioxidant capacity (TAC) of the edible oils. The method explores the ABTS radical (2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid)) assay as a redox probe and it relays on measuring catalytic voltammetric currents. The electrocatalysis comprises redox regeneration of the electrochemically creat...

Adulteration of edible vegetable oils is a very serious problem affecting its commercial value and customers’ health. FT-NIR and Confocal Micro-Raman have been explored for discriminating adulteration of sesame oils. The soybean, corn, and peanut oil were mixed into sesame oils in the range of 5~20%(v/v),respectively,and their Confocal Micro-Raman and FT-NIR spectra were collected. Principal co...

BACKGROUND For appropriate advising on a meal plan aimed at the prevention of ischemic heart disease, it is necessary to know the chemical composition of foods. OBJECTIVE To analyze the composition of fats, fatty acids and cholesterol in some Brazilian specimens of edible oils, butter, margarines, dairy products and eggs, using the limits of a diet to prevent coronary artery disease. METHOD...

This article through the description cooking oil quality backward system setup procedure, proposed that in food tracing referral system's data acquisition and the polling message system establishment's essential factor, the implementation and the application, the system including the tracing database, the information acquisition, the network transmission and many kinds of inquiry terminals, int...
