What are examples of raw materials?
Examples of raw materials include: steel, oil, corn, grain, gasoline, lumber, forest resources, plastic, natural gas, coal, and minerals.
What can we extract from fish?
Summary: New industrial processing techniques are enabling us to obtain valuable proteins, antioxidants and oils from salmon and rapeseed waste. These extracts can be used in health foods, nutritional supplements and skin care products.
Which two important products of our use are made from fish wastes?
These wastes can be used to produce fish protein concentrate, fish oils and enzymes (such as pepsin and chymotrypsin) as well as other value added products. The fish oil is used for products such as margarine, omega-3 fatty acids and biodiesel. The fish protein concentrate is used as human food and animal feed.
What is raw material in food?

Are fish killed for fish oil?
No fish have to be killed, and it’s a very sustainable way of producing omega-3s. There are also supplements that aren’t based on the giant reduction industry that produces most fish oil, but rather on fish waste. There’s a very good brand called Pure Alaska Omega that uses off cuts from the salmon industry in Alaska.
How do you extract Omega-3 from fish?
The omega-3 extraction process starts at industrial sites (Kolanowski, 2005). Here the water is removed from the oil with a 3-phase centrifuge. As mentioned above, most of this oil is then used in aquaculture to ensure that the farmed fish also contain a minimum amount of omega-3 fatty acids.
What part of the fish does fish oil come from?
Fish oil is the fat or oil that’s extracted from fish tissue. It usually comes from oily fish, such as herring, tuna, anchovies, and mackerel. Yet it’s sometimes produced from the livers of other fish, as is the case with cod liver oil.
