Mycoprotein

Mycoprotein is defined in the Oxford English Dictionary as: "the albuminoid which is the principal constituent of the protoplasm of the cell." "Myco" is from the Greek word for "fungus".

Mycoprotein means protein from fungi. It can be used as part of any meal, particularly vegetarian. The main mycoprotein on sale in Europe and the USA is called Quorn. It was originally developed as a food source to combat food shortages.

A fungus called Fusarium venenatum is the main source of mycoprotein. The fungus is grown in vats using glucose syrup as food. This Fusarium sp. respires aerobically, so for it to grow at an optimum rate, it is supplied with oxygen. To make protein, nitrogen (in the form of ammonia) is added, and vitamins and minerals are needed to support growth. The vat is kept at a constant temperature, also optimized for growth; The fungus can double its mass every five hours.

The fermentation vat is filled with the growth medium, and then inoculated with the mould. When the desired amount of mycoprotein has been created, the growth medium is drawn off from a tap at the bottom of the fermenter. The mycoprotein is separated and purified. It is a pale yellow solid with a faint taste of mushrooms. Different flavours and tastes can be added to the mycoprotein to add variety.

The protein is known as a single cell protein (SCP) and was first produced in the early 1980's.
