The oil content of flaxseed ranges from 400 to 450g/kg and the byproduct of mechanical oil extraction - flaxseed (or linseed) meal - can be used in organic poultry feeding. There is also interest in feeding the ground whole oil-containing seed to poultry for two main reasons to produce meat with a fatty acid profile in the fat that confers health benefits to the consumer (Conners, 2000) and to impart an enhanced flavour to the meat. 

D, for soybean oil during the initial period or its extraction from soybeens with hexane is around 1.0 x 10 10 m2/s but drops off to 0,12-0.2 times that value at the end of extraction.13 Both initial and final D, values for cottonseed and flaxseed are roughly only 0.1 times as large as the corresponding initial and final values for soybeans and the extraction times required when these oils are extracted commercially is considerably longer than that for soybeans. 

Fatty acid composition of total lipids extracted from crushed flaxseeds with hexane or methanol-ammonia-water/hexane (95 10 5, v/w/v) solvent systems did not show any considerable difference (Wanasundara and Shahidi, 1994a) and retained the same proportion of polyunsaturated, monounsaturated and saturated fatty acids. However, when oil-extracted flaxseed meal was further extracted with methanol-ammonia-water/hexane (90 5 5, v/w/v) system the amount of ALA in the residual oil so extracted was almost 50% less than that extracted with hexane (Oomah et ai, 1996). 

Various methods could be used to reduce the cyanogenic glycosides content in the seed. Wanasundara et al. (1993) investigated the use of solvents extraction as a means to reduce cyanogenic glycosides content of flaxseed meal. They found that extraction of flaxseed with alkanol-ammonia-water/ hexane resulted in enhanced removal of cyanogenic compounds from 41 to...

Table 4.1.10A. Flaxseed (linseed) expeller (IFN 5-02-045). The product obtained by grinding the cake or chips which remain after removal of most of the oil from flaxseed by a mechanical extraction process. It must contain no more than 100 g fibre/kg. (From AAFCO, 2005.)...

The first domestic crushing of soybean occurred in Seattle, Washington, in 1910, using seed imported from Manchuria.152 Domestically produced soybean was crushed at cottonseed oil mills in the South and linseed (flaxseed) oil mills in the Midwest during the 1910-1920 era.152,156 The first commercially successful domestic soybean solvent continuous extraction plants were installed by Archer Daniels Midland Company (ADM) and the Glidden Company in Chicago in 1934, both using 100 tpd Hildebrandt U-tube extractors and commercial hexane as solvent. They also were equipped to produce phosphatides.153... 

Solin Oil occurs as a light yellow oil. It is obtained from the seed of certain varieties of the flaxseed plant Linum usitatissi-mum L. (Fam. Linaceae) by mechanical expression and/or solvent extraction, differing from linseed oil in having a linolenic acid (C18 3) content of less than 5%. The oil is refined, bleached, and deodorized to remove free fatty acids, phospholipids, color, odor and flavor components, and miscellaneous non-oil materials. It is liquid and free from visible foreign material at 21° to 21°, but traces of wax may cause the oil to cloud at refrigeration temperatures (2° to 5°) unless removed by winterization.
