Mycoprotein
Encyclopedia
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 North America 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 spores. 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 a form of single cell protein
(SCP) and was first produced in the early 1980s.
Some consumers are sensitive to mycoproteins, resulting in vomiting
, nausea
, diarrhea
, hives and potentially fatal anaphylactic reactions.

Cell (biology)
The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. The Alberts text discusses how the "cellular building blocks" move to shape developing embryos....

Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate , and then release waste products. The reactions involved in respiration are catabolic reactions that involve...
