Why roast pistachios?

Companies roast pistachios for some reason. Raw pistachios carry out bacteria like salmonella and aflatoxin. Salmonella infection can cause a range of intestinal symptoms from diarrhea to fever to abdominal cramps, nausea, vomiting, and headaches. 

An aflatoxin is a group of toxins that cause some symptoms like nausea, vomiting, abdominal pain, convulsions, and other signs of acute liver injury.

Roasting pistachios give them a crunchy taste as well. They add spices and salt to pistachios before roasting them and roasting makes the spices stick to it. 

Roasting pistachios makes them easier to digest and easier to eat when they lose their shells.

What are the two kinds of roasting?

Roasting pistachios has two kinds. One kind is to roast them without oil or water. The other type is oil roasting. 

Dry roasting, it needs no oil or water to roast them. You just need a pan and a source of heat, like an oven for about a quarter-hour. You can use a microwave as well.

Oil roasting is done when pistachios are sprayed with a thin layer of oil as they move on a conveyor belt. Adding oil adds fat content to pistachios.

How are raw and roasted pistachios different?

Raw pistachios and roasted ones are different in some ways. Raw pistachios have more fiber content than roasted pistachios. With oil-roasted pistachios their caloric intake and fat content increase as a result of the oil addition. 

Roasting does not alter the fatty acid profile. It also kills bacteria like salmonella using the high heat used in roasting. And it also destroys toxins such as aflatoxin.
