The study was carried out on the canola (Brassica napus L.) cv. TP3 Hpro, in order to select the processing method most suitable to the technological facilities available in Vietnam and to optimize the processing techniques. The canola seeds of TP3 Hpro (with 41.99 percent oil content) introduced from Australia were sown in 2010-2011 winter-spring season in Ha Giang province. Expeller pressing, where raw materials are squeezed under high pressure in a single step, is the most suitable method that could be easily implemented in Vietnam to extract oil from the canola seeds. The main processing factors were examined in order to enhance the oil extraction yield and oil quality. The optimised processing conditions are listed as follows. The seeds were crushed to coarse powder with particle size of 1 mm. The powder was then steamed at 100°C for 50 min, followed by a drying step at 90°C for 12 min. After that, the powder was placed in the pressing equipment and was acclimatised at 55°C before being pressed. The pressing capacity was 9 kg of powder per hour. The canola oil obtained was classified as salad oil with high nutritional values since it does not contain erucic acid, yet has relatively high levels (19.2 percent) of essential unsaturated fatty acids, such as omega-3 and omega-6.
