Ward and published by . This book was released on 1994 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High levels of chlorophyll in harvested canola seed cause an increase in processing costs, lower returns for producers and poorer quality end products. The effects of genotype, environment and agronomic practices on seed chlorophyll levels were investigated in this study. When canola seed was frozen for up to one month, either in the pods or after removal, no significant reduction in chlorophyll was observed. Results from a swathing study indicate that seeds from the side branches contained 1.5 to 2 times as much chlorophyll as seeds from the main stems. Seed that was dried rapidly contained 1.5 to 6 times as much chlorophyll as seed allowed to mature in swaths in the field. When seeds from each treatment in the swathing study were subdivided according to size, the smallest seeds were found to contain the most chlorophyll. Seed from the treatments with the highest chlorophyll levels also contained the greatest amount of small seed. Chlorophyll degradation rates were investigated in four cultivars of Brassica napus as the seed ripened. No significant differences in the rate of chlorophyll breakdown were found between the different cultivars tested. Cultivars that require longer growing seasons to reach maturity were found to initiate seed chlorophyll degradation later in the growing season, increasing the chances that high levels will remain when the seed is harvested. The environment did affect the rate of chlorophyll degradation, as slower breakdown rates did occur in later sown plots. This was assumed to be due to the lower daily mean temperatures which occured later in the growing season. A number of cultivars of both B. napus and B. campestris grown at sites throughout Manitoba were measured for seed chlorophyll levels at harvest. No significant differences were found among different cultivars of B. campestris but the final chlorophyll levels of B. napus seed were extremely variable, both among triazine tolerant cultivars and those without triazine resistance. The environment also affected the seed chlorophyll level and there was a significant genotype by environment interaction. Seed samples of a number of cultivars taken from high chlorophyll sites were subdivided according to size and the smallest seeds were found to contain the most chlorophyll. The relationship between the percentage of small seed in any sample and the chlorophyll level was less defined in the "Agroman" material than in the swathing study.

Book excerpt: Chlorophyll is normally removed from canola seeds during the natural maturing process and usually has disappeared completely by the time the canola is mature. Chlorophyll retention can be caused by improper ripening, frost, disease, or drought. This project was conducted to examine methods of reducing chlorophyll in harvested canola. Two batches of canola were harvested and subjected to various in-bin treatments. Chlorophyll, moisture content, and other factors were monitored during the tests.

Available in PDF, EPUB and Kindle. Book excerpt: Rapeseed is now the second largest oilseed crop after soybean, and the third largest vegetable oil after soybean oil and palm oil, and it is therefore an important contributor to the annual supply of vegetable oils required to meet an increasing demand. This volume provides comprehensive coverage of rapeseed oil and its close relative, canola oil, from production (agronomic) aspects, through extraction to refining and processing. Chemical composition, physico-chemical properties, food and non-food uses are considered in detail, and a chapter is included on future prospects, including oils available by means of genetic manipulation. This is a book for oils and fats chemists and technologists in the food and oleochemical industries, chemical engineers in the processing industry, nutritionists and seed technologists.

Available in PDF, EPUB and Kindle. Book excerpt: In 2010, esteemed researchers gathered at a workshop held at the Richardson Centre for Functional Foods and Nutraceuticals at the University of Manitoba in Winnipeg, Canada. Drawn from these proceedings, Canola and Rapeseed: Production, Processing, Food Quality, and Nutrition presents state-of-the-art information on the chemistry of the minor constituents of canola and rapeseed and their impact on human health. The book also identifies new areas of research and opportunities for the industrial application of functional foods and nutraceuticals from canola and rapeseed. Topics include: The historical development, properties, and performance of canola Characteristics and bioactives of sinapic acid derivatives and the decarboxylation pathways leading to their formation Canola protein processing High omega-9 canola oils and their future applications Modification of Brassica oilseeds Rapid analytical methods for measuring oil content The potential of ultrasound and supercritical fluid extraction for producing value-added by-products The processing of virgin rapeseed oils in Europe Extraction and application of canola protein The frying stability of high-oleic low-linolenic acid canola oils The potential of mustard oil for biodiesel The final chapters demonstrate the health benefits of canola, including antioxidant, antimutagenic, and anticancer properties. Authored by experienced researchers in the field, the book chapters have been expanded considerably to include a number of areas not contained in the original workshop, providing comprehensive coverage of the potential of this essential crop.
