Changes of lipid in salted-dried hair tail fish, trichiuras lepturus linnaeus

To investigated the effective method of preventing the rancidity of lipid in the storage of the salted-dried hair tail fish, the changes of composition of lipids and fatty acids during the storage were examined by column and gas chromatography. The results were summarized as follows. 1. During the storage, acid value were increased in the control and decreased in the BHA adding treatment. 2. The peroxide value showed 41.5meq/㎏ in the control after drying were increased 2.4 times during the storage. In the case of BHA adding treatment were increased a little. 3. In the changes of lipid composition, neutral lipid of control and BHA adding treatment were decreased, phospholipid were increased during the storage. 4. The major fatty acid composing the saturated fatty acid in the salted-dried hair tail fish were 16;0, 18;0, 14;0 acid and unsaturated fatty acid were 18;1, 22;6, 16;1, 20;5, 22;6 acid in order. During the storage, the changes of saturates were increased and unsaturated were decreased. It was concluded that drying the storage, BHA-packed(PP) samples were resulted effective method of preventing the oxidation lipid.
