A team of researchers from Iwate have discovered that the small Pacific krill, locally known as isada, has components that prevents the accumulation of neutral fats in the human body.
The fisheries sector is expecting that this scientific discovery, released just as the fishing season for Pacific krill (Euphausia pacifica) begins on Tuesday 1 March, will act as a trigger for increased demand for this crustacean.
The research team comprises of scientists from the Biotechnology Research Center of Iwate of the Marine Technology Prefecture Center of Iwate and the Iwate Medical University.
The team began to conduct studies on the functionality of marine resources in 2009. As part of their research, scientists discovered that water soluble extracts obtained from this type of krill can contain the expression of two genes -PPARγ or C/EBPα- which are needed to form fat cells in humans.
During an experiment with mice, researchers found that normal body weight did not increase even though they had consumed high-calorie foods.
Scientists believe it is possible to include those components of this small crustacean in processed foods because they can withstand cooking, ie they can be roasted and fried.
Meanwhile, the team has already applied a patent for this discovery.
