Canola is an important oil crop for farmers in southern Australia and contributes millions of dollars in agricultural and food-sector earnings. New varieties are needed to address many factors, one of which is the “development of new export markets and uses for Australian oilseeds and products including new health and functionality oils” (Australian Oilseeds Federation Strategic Plan). Tocopherols and carotenoids are two classes of compounds that may confer health-enhancing properties and functionality to canola oil, yet few studies have been undertaken to simultaneously quantify these compounds in Australian canola varieties. The present study investigated 156 canola oilsamples comprising 28 varieties collected from 14 different locations in southern NSW. Standard oil quality parameters were assessed along with quantitation of α-, γ-, and δ-tocopherol, β-carotene and lutein. Results will be presented on correlations among the various quantities measured as well as a REML analysis of G × E effects. The latter analysis showed that the major effect on levels of tocopherols and carotenoids was variety, opening up the possibility of breeding programs targeting genotypes with enhanced levels of these compounds.

Abbreviated titleFood vs Fuels
OtherThe AAOCS (Australian Section of the American oil chemists’ society) is holding their biannual meeting at Noah’s on the Beach Newcastle Australia on the 6-8th of November. This year’s theme will be on the Food vs. Fuels debate. Plant oil production is currently almost entirely directed to human food uses. Yet these oils also represent the most prospective renewable resource for production of numerous industrial products, such as transportation fuels, industrial chemicals and polymers, which are currently derived from petroleum. A major challenge, and opportunity, is to dramatically increase global production of plant oils to not only meet increasing food demand for a burgeoning world population, but also to provide sufficient surplus to enable use as renewable industrial oils. This challenge is very important for the oilseed industry, and is the subject of the upcoming AAOCS meeting biennial meeting.
