Marmite

Marmite ( ) is a food spread made from yeast extract invented by German scientist Justus von Liebig and originally made in the United Kingdom. It is a by-product of beer brewing and is currently produced by British company Unilever. The product is notable as a vegan source of B vitamins, including supplemental vitamin B12.
Marmite is a sticky, dark brown paste with a distinctive, salty, powerful flavour. This distinctive taste is represented in the marketing slogan: "Love it or hate it." Such is its prominence in British popular culture that the product's name is often used as a metaphor for something that is an acquired taste or tends to polarise opinion. Marmite is commonly used as a flavouring, as it is particularly rich in umami due to its very high levels of glutamate (1960 mg/100g).
The image on the jar shows a "marmite" (), a French term for a large, covered earthenware or metal cooking pot. Marmite was originally supplied in earthenware pots but since the 1920s has been sold in glass jars.
Similar products include the Australian Vegemite (whose name is derived from that of Marmite), the Swiss Cenovis, the Brazilian Cenovit and the German Vitam-R. Marmite has been manufactured in New Zealand since 1919 under licence but with a different recipe. That product is the only one sold as Marmite in Australasia and the Pacific, whereas, elsewhere in the world, the European version predominates.
History.
The product that was to become Marmite was invented during the late 19th century when German scientist Justus von Liebig discovered that brewer's yeast could be concentrated, bottled and eaten. During 1902, the Marmite Food Extract Company was formed in Burton upon Trent, Staffordshire, England with Marmite as its main product and Burton as the site of the first factory. The by-product yeast needed for the paste was supplied by Bass Brewery. By 1907, the product had become successful enough to warrant construction of a second factory at Camberwell Green in London.
By 1912, the discovery of vitamins was a boost for Marmite, as the spread is a rich source of the vitamin B complex;
with the vitamin B1 deficiency beriberi being common during World War I, the spread became more popular. British troops during World War I were issued Marmite as part of their rations.
During the 1930s, Marmite was used by the English scientist Lucy Wills to successfully treat a form of anaemia in mill workers in Bombay. She later identified folic acid as the active ingredient. Marmite was used to treat malnutrition by Suriya-Mal workers during the 1934–5 malaria epidemic in Sri Lanka. Housewives were encouraged to spread Marmite thinly and to "use it sparingly just now" because of limited rations of the product.
During 1990, Marmite Limited, which had become a subsidiary of Bovril Limited, was bought by CPC International Inc, which changed its name to Best Foods Inc during 1998. Best Foods Inc subsequently merged with Unilever during 2000, and Marmite is now a trademark owned by Unilever.
Similar products.
There are a number of similar yeast products available in other countries; these products are not directly connected to the original Marmite recipe and brand. The Australian product Vegemite is distributed in many countries, and AussieMite is sold in Australia. Other products include OzeMite, which is made by Dick Smith Foods; Cenovit, a Brazilian spread; Vitam-R, a German spread; Cenovis, a Swiss spread; and Vegex, an autolyzed yeast product available in the United States since 1913.
Usage.
Marmite is traditionally eaten as a savoury spread on bread, toast, savoury biscuits or crackers, and other similar baked products. Owing to its concentrated taste it is often spread thinly with butter or margarine. Marmite can also be made into a savoury hot drink by adding one teaspoon to a mug of hot water, much like Oxo and Bovril. Marmite is also commonly used to enrich casseroles and stews.
Marmite is often paired with cheese, such as in a cheese sandwich, and has been used as an additional flavouring in Mini Cheddars, a cheese-flavoured biscuit snack. Similarly, it is one of Walkers Crisps flavours; is sold as a flavouring on rice cakes; and is available in the form of Marmite Biscuits. Starbucks in the UK has a cheese and Marmite panini on its menu.
Marmite has been used as an ingredient in cocktails, including the Marmite Cocktail and the Marmite Gold Rush.
Celebrity chef Nigella Lawson created a recipe for Marmite spaghetti, and Heston Blumenthal produced a recipe for Marmite consommé.
In 2020, Marmite launched a campaign called The Great Marmite Experiment on Instagram in which they encouraged users to share their marmite recipes. Entries included roast potatoes, beef wellington, cookies and more.
Manufacture.
While the process is secret, the general method for making yeast extract on a commercial scale is to add salt to a suspension of yeast, making the solution hypertonic, which results in the cells shrivelling; this triggers autolysis, during which the yeast self-destructs. The dying yeast cells are then heated to complete their breakdown, and since yeast cells have thick cell walls which would detract from the smoothness of the end product, the husks are sieved out. As with other yeast extracts, Marmite contains free glutamic acid, the monosodium salt of which being monosodium glutamate.
Presently, the main ingredients of Marmite are glutamic acid-rich yeast extract, with lesser quantities of salt, vegetable extract, spice extracts and celery extracts, although the precise composition is a trade secret. Vitamins added for food fortification include riboflavin, folic acid, and Vitamin B12. Vitamin B12 is not naturally found in yeast extract, but is very important for vegans who are at risk of deficiency.
Nutritional information.
Marmite is rich in B vitamins including thiamin (B1), riboflavin (B2), niacin (B3), folic acid (B9) and vitamin B12. The sodium content of the spread is high and has caused concern, although it is the amount per serving rather than the percentage in bulk Marmite that is relevant. The main ingredient of Marmite is yeast extract, which contains a high concentration of glutamic acid. Marmite is not gluten free, as it is made with wheat, and although it is thoroughly washed, it may contain small quantities of gluten.
Marmite should be avoided if a person takes a MAOI antidepressant, such as phenelzine (Nardil) or tranylcypromine (Parnate), as yeast extracts interact adversely with these types of medications due to their tyramine content.
Marmite is presently fortified with added vitamins, resulting in it being banned temporarily in Denmark, which disallows foodstuffs that have been fortified until they have been tested. The Danish Veterinary and Food Administration stated during 2015 that Marmite had not been banned in the country, but that fortified foods need to be tested for safety and approved before they can be marketed in the country. During 2014, suppliers applied for a risk assessment to be performed after which Marmite became available in Denmark.
Storage.
Marmite should be stored in the dark and kept cool, but should not be refrigerated. The 'Best before' date is guidance for loss of vitamins rather than safety. Marmite is still safe to eat decades after manufacture.
Marketing and packaging.
Marmite's publicity campaigns initially emphasised the spread's healthy nature, extolling it as "The growing up spread you never grow out of". The first major Marmite advertising campaign began during the 1930s, with characters whose faces incorporated the word "good". Soon afterwards, the increasing awareness of vitamins was used in Marmite advertising, with slogans proclaiming that "A small quantity added to the daily diet will ensure you and your family are taking sufficient vitamin B to keep nerves, brain, and digestion in proper working order".
During the 1980s, the spread was advertised with the slogan "My mate, Marmite", chanted in television commercials by an army platoon. The spread had been a standard vitamin supplement for British-based German POWs during the Second World War.
By the 1990s Marmite's distinctive and powerful flavour had earned it as many detractors as it had fans, and it was known for producing a polarised "love/hate" reaction amongst consumers. For many years television advertisements for Marmite featured the song "Low Rider" by the band War with the lyrics changed to the phrase "My Mate, Marmite". Marmite began a "Love it or Hate it" campaign during October 1996, and this resulted in the inventing of the phrase "Marmite effect" or "Marmite reaction" for anything which provoked controversy. On 22 April 2010, Unilever threatened legal action against the British National Party for using a jar of Marmite and the "love it or hate it" slogan in a party political broadcast.
Availability worldwide.
Because of the local product named Marmite, European Marmite is sold by the name "Our Mate" in Australia and New Zealand. New Zealand Marmite uses the name "NZ-Mite" elsewhere.
In Denmark, food safety legislation dictates that foodstuffs that contain added vitamins can only be sold by retailers which have been licensed by the Veterinary and Food Administration. During May 2011, the company that imports the product to Denmark revealed that it wasn't licensed and had therefore stopped selling the product: this resulted in widespread but inaccurate reports by the British media that Marmite had been banned by the Danish authorities.
Canada.
On 24 January 2014, the Canadian Food Inspection Agency was noted, in a Canadian Broadcasting Corporation story, as preparing to stop the sale of Marmite, as well as Vegemite and Ovaltine, in Canada because they were enriched with vitamins and minerals which were not listed by Canadian food regulations. The agency said the products were not a health hazard.
The CFIA later specified that these specific items had been seized because they were not the versions that are formulated for sale in Canada and which satisfied all Canadian food regulations. Canadian versions of Marmite and the other products would still be permitted to be sold in Canada.
South Africa.
Marmite is manufactured by licence in South Africa by Pioneer Foods in its traditional form. 
South Africa also produces a bottled, long-life Marmite-flavoured Cheese Spread, which is extremely popular in that country. It is light in texture and contains a hint of Marmite, making in more palatable to Marmite novices. . 
In addition, Lancewood, a major dairy producer in South Africa, manufactures a fresh Full-cream Cheese Spread, flavoured with Marmite, especially for those who prefer fresh dairy over the long-life variety. 
Also immensely popular in South African baking corners, is a sweet and savoury tea cake that is topped with a hint of Marmite-butter and grated cheese. 
Special editions.
During 2002 a 100th anniversary jar was released.
During February 2007, Marmite produced a limited edition Guinness Marmite of 300,000 250g jars of their yeast extract with 30% Guinness yeast, giving it a noticeable hint of "Guinness" flavour. During January 2008 Champagne Marmite was released for Valentine's Day, with a limited-edition production of 600,000 units initially released exclusively to Selfridges of London. The product had 0.3% champagne added to the recipe, and a modified heart-shaped label with "I love you" in place of the logo.
During 2009, a limited edition Marston's Pedigree Marmite was initiated to celebrate the 2009 Ashes Cricket test series.
During March 2010, a super-strong blend called Marmite Extra Old, abbreviated as XO, was initiated in the UK. Normal Marmite contains a mix of lager, bitter and ale varieties of yeast, sourced from breweries throughout the UK. However, as lagers have a lighter, sweeter taste, residue from this product is not used in Marmite XO. Only residue from traditional bitters and ales are blended to ensure the stronger taste. Marmite XO is matured for 28 days - four times longer than usual. Continuing the tradition of different coloured caps for special editions, Marmite XO's cap is black.
During April 2012, a special edition jar in commemoration of the Diamond Jubilee of Queen Elizabeth II was released. With the product renamed "Ma'amite," the redesigned label featured a colour scheme based upon the Union Jack; the marmite and spoon logo replaced by a gold crown, and with a red rather than yellow cap. The front label also declares "Made with 100% British Yeast". Coinciding with the 110th anniversary of the brand, production was limited to 300,000 jars. For Christmas 2012 a gold limited edition was begun, containing edible gold-coloured flecks.
Marmite chocolate is also available.
During 2015, Marmite Summer of Love Special Edition featured a flower power themed label. This special edition's blend had a lighter taste made using 100% Lager yeast.
In July 2019, Marmite XO returned due to popular demand.
