Understanding the Ingredients in Oxo Cubes
Oxo cubes have been a staple in British kitchens for decades, valued for their convenience and ability to add a flavour boost to countless dishes. However, with growing consumer awareness about food additives, many are scrutinising ingredient lists more closely. A primary question for many is: do Oxo cubes have MSG in them?
The answer is straightforward, though with some important nuances depending on the specific product variant. The vast majority of standard Oxo cubes—including the classic beef, chicken, and vegetable versions—list flavour enhancers, including monosodium glutamate (MSG or E621), among their ingredients. The purpose of this addition is to enhance the meaty or savoury 'umami' flavour profile of the stock.
The Role of MSG and Flavour Enhancers
Monosodium glutamate (MSG) is a sodium salt of glutamic acid, a naturally occurring amino acid. It is known for its ability to intensify the savoury, or umami, taste in foods. In Oxo cubes, it works in conjunction with other ingredients, such as yeast extract, to create a fuller, richer flavour than dried stock alone would provide.
Another common flavour enhancer found alongside MSG in some Oxo products is disodium guanylate (E627) or disodium 5'-ribonucleotides (E635). These compounds work synergistically with MSG to further boost the umami taste, allowing manufacturers to use less MSG while still achieving the desired flavour impact. The result is a highly concentrated seasoning that adds depth to soups, stews, and sauces.
Which Oxo Cubes Contain MSG?
For those looking to check specific products, a quick look at the packaging is the most reliable method. The ingredients are always listed, and flavour enhancers are clearly identified. However, based on available product information, here is a general breakdown:
- Oxo Beef Cubes: Contain monosodium glutamate (E621) and disodium guanylate (E627).
- Oxo Chicken Cubes: Contain monosodium glutamate (E621).
- Oxo Vegetable Cubes: Contain monosodium glutamate (E621) and disodium 5'-ribonucleotides (E635).
It is important to note that Oxo also offers other products, such as stock pots, which may have different formulations. Some specialised versions, such as certain vegan or reduced-salt products, might be formulated differently, but reading the label is always the most accurate approach.
The Debate Surrounding MSG
Despite its widespread use, MSG has been the subject of controversy for many years. Some individuals report symptoms like headaches, flushing, and sweating after consuming it, a phenomenon once colloquially referred to as 'Chinese restaurant syndrome'. However, regulatory bodies like the U.S. Food and Drug Administration (FDA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have classified MSG as generally recognised as safe. Extensive research has failed to establish a conclusive link between normal MSG consumption and these reported symptoms.

Other Things to Consider
When evaluating Oxo cubes for your diet, MSG is just one ingredient to consider. These products are also typically high in sodium, which can be a concern for individuals with high blood pressure or those monitoring their salt intake. Some varieties, particularly the beef and chicken, contain allergens like wheat and gluten. Many people prefer to use homemade stocks made from scratch to have complete control over the ingredients, sodium content, and flavour profile.
For those seeking alternatives, Oxo's own stock pots are all gluten-free, though it is always essential to check the specific labelling for information on other ingredients and allergens. You can also find low-sodium versions and vegan options on the market, catering to various dietary needs.
Conclusion
In summary, most standard Oxo cubes do contain MSG as a flavour enhancer to achieve their characteristic savoury taste. This includes the beef, chicken, and vegetable varieties. While MSG has a controversial history, it is generally considered safe by major food safety authorities. Consumers concerned about MSG, sodium, or gluten should always read the product labels carefully or consider using fresh, homemade stock as an alternative for full control over ingredients.
A Deeper Look at Flavour and Health
For those interested in exploring the health implications of MSG and other flavourings, the National Institutes of Health (NIH) offers a range of peer-reviewed articles and studies. For example, a paper published in PubMed Central discusses the extensive use of MSG and possible health considerations, offering valuable context on the topic.

This confirms that while MSG is a common ingredient, informed choice requires understanding its presence and role alongside other components of these popular kitchen items.
