The market for cold pressed Flax seed oil is growing both domestically and internationally due to its excellent nutritional benefits. Saskatchewan farmers grow significant acres of flax each year for oil production, the major market is China which has increased its imports of flax dramatically in recent years. This project will work to optimize the cold pressing regime of TA Foods. Different batches of flax seed yield oil with differing levels of free fatty acids during the cold pressing process. Under similar conditions some batches of flax seed have low levels of free fatty acids, others have much higher levels. High fatty acid levels are not desirable as this indicates that the triglycerides have started to break down releasing free fatty acids, this can lead to an off taste in the oil and shorten its self-life. We will be looking at several factors that may influence the acidity of the oil after processing including agronomic factors in growing the flax, different storage conditions and some variables within the crushing process itself. The results of this study should help TA Foods to produce a more consistent product and perhaps assist them in knowing which factors are important in purchasing seed stock for crushing.

冷榨亚麻籽油的市场由于其优异的营养价值而在国内和国际上都在增长。萨斯喀彻温省的农民每年种植大量的亚麻用于油料生产，主要市场是中国，近年来中国大幅增加了亚麻的进口。该项目将致力于优化TA食品的冷压制度。不同批次的亚麻籽在冷榨过程中产生具有不同水平的游离脂肪酸的油。在类似的条件下，一些批次的亚麻籽的游离脂肪酸水平较低，其他批次的水平则高得多。高脂肪酸水平是不可取的，因为这表明甘油三酯已经开始分解释放游离脂肪酸，这可能导致油中的异味并缩短其自身寿命。我们将研究几个可能影响加工后油酸度的因素，包括种植亚麻的农艺因素，不同的储存条件和粉碎过程本身的一些变量。这项研究的结果应该有助于TA食品生产更一致的产品，也许有助于他们知道哪些因素是重要的，在购买种子股票粉碎。
