An improved system for measuring antioxidant activity via thiobarbituric acid reactive substances and ferric thiocyanate assays is reported, on the basis of oxidation of a linoleic acid (LA) emulsion. Oxidation times were reduced from 20 h to 5 h by increasing the reaction temperature from 37 °C to 50 °C and with an acceptable precision of <10% coe...
Article
The thiobarbituric acid reactive substances (TBARS) assay is widely used to measure lipid oxidation and antioxidant activity in food and physiological systems. However, there has been no review (to our knowledge) that focuses exclusively on this test. This review presents an overview of the current use of the TBARS test in food and physiological sy...
Article
The thiobarbituric acid reactive substances (TBARS) assay is widely used to measure antioxidant activity in the presence of lipid substrates such as linoleic acid (LA). In one version of this assay, LA is oxidized with and without antioxidant in a multi‐phase system in which LA lies over the surface of the aqueous layer of catalyst and antioxidant...
Article
The production of olive oil comprises a number of production steps where the quality of the oil may be controlled through an understanding of how the production step influences key compounds such as volatiles and biophenols. In this study, critical production steps and significant inter-relationships between isolated production steps from fruit to...

Copigmentation is a very important contributor to colour in young red wines. Further understanding of the copigmentation effect has been elucidated by investigating the contribution of various fractions of grapes – skin, pulp, and seed – in varieties Shiraz, Sangiovese and Pinot Noir. A series of spectrophotometric and HPLC experiments elucidated t...
Chapter
ion has been a frequent discussion topic since the days of Aristotle and Plato. Constructivist theories often espouse the notion of levels of abstraction. Hiebert and Lefevre (1986, pp. 4-5) put it this way: It is useful to distinguish between two levels at which relationships between pieces of mathematical knowledge can be established. One level w...

Learning to write is a process where preverbal ideas (thoughts) are transformed into a written form. Such written forms produced vary from words to sentences to higher forms of discourse such as essays, reports, researches, reviews, poems, stories, dialogues, etc. These written forms that are generated, formed, and activated from thoughts are then...

Final report of the the Active Learning in University Science (ALIUS) project. This project aims to establish a new direction in first year chemistry teaching – away from didactic teaching methods in large lecture style teaching to more active, student centred learning experiences. Initially six universities have been involved in practice-based i...
