OMEGA 3

OMEGA 3
introduction


Omega-3 fatty acid, DHA and EPA are contained in fish oil. Depending on fish type, its contents vary a lot. Generally, it is found in salmon, sardine, tuna, etc. Products sold as a health functional food mainly use this fish oil as materials. Normally, it is extracted from fish liver and for a long time, raw materials extracted from cod liver have been used globally. In addition to that, it is sometimes found in algae.

Omega 3

The THREE main functions of
OMEGA 3


Omega 3
01EPA and DHA intake

EPA and DHA in body are existed as esterified status in phospholipid, membrane of tissue, plasma lipoprotein, etc. The result of study that Japanese that intake of EPA and DHA is relatively higher by five to ten times than western people (Kamada, et al, 1986; Terano, et al, 1983) supports it

Omega 3
02Omega 3 of Health Functional Foods

Keeping of omega-3 fatty acid contents in health functional food uses edible fish, sea seal as raw materials, extracts them through heating, pressing, hexane, and CO2, and filter them to make suitable for eating. After extracting as the above method, actual product manufacturing goes through the process of deguming, deoxidation, decoloration, and deodorization.

Omega 3
03Omega 3 of raw materials

According to each raw material, raw materials from edible fish manages over 18% EPA and DHA, raw materials from sea seal over 12% and raw materials from algae over 30%. In case it does not go through an esterification process that increases the contents of EPA and DHA, it is reported that 18~45% in raw materials from edible fish, 12-18% in raw materials from sea seal and 30~50% in raw materials from algae. In the healthy functional food standards codex (2008-12), as safety of raw materials that went through esterification process was not confirmed, it was excluded as standard raw materials. Afterwards, by reviewing it individually, it made esterification process be able to use.

safety
evaluation


Omega-3 fatty acid is food that has been eaten safely for a long time However FDA recommends not to take over 3G of OMEGA-3 fatty acid from fish oil a day. Even though it is not serious toxicity. Its fat contains much fat soluble vitamin which is cautious. However, The volume and respose effect on OMEGA-3 fatty acid is not clear. Eskimo eats 6.5G OMEGA-3 fatty acid a day. But any special adverse effect is not observed. In case 3G DHA and EPA are eaten a day, special adverse effect has not been reported except for adverse effect in stomach. (LEAF, ETC. 1994) As a result to review various literatures to improve blood flow and to determine intake volume that controls neutral fat in blood, minimum intake volume was set as 500 mg by referring result of DART study and Kris-Etherton, etc (2002). We recommend proper intake volume of DHA and EPA in healthy functional food is 0.5 to 2g per day considering under 3g restricted by U.S.A. FDA and intake of omega-3 from meal.
