Abstract
|
|
|
For removal of trimethylamine (TMA) which is generally accepted as the main component of marine fish oiler and the lipids in marine fish which contribute directly or indirectly to the odor of fish flour, extractions of raw Cololabis saira were carried out with Ethanol-Water Mixture or Absolute Ethanol. Results obtained are as follows:
1. Efficient extraction of TMA from raw Cololabis saira took place when final concentration of ethanol was 40%∼55%.
2. When successive extraction of raw Cololabis saira was carried out with boiling absolute ethanol, the extraction proceeded in two distinct stages:
a) In the first stage, efficient dehydration of raw Cololabis saira and efficient TMA extraction took place simultaneously.
b) In the second stage, efficient lipid extraction followed after the dehydration stage.
