A Closer Look at Wotsits' Flavourings
The ingredient list for Walkers Wotsits can differ between flavours and product types (e.g., standard, Giant, Crunchy). Therefore, simply asking "do Wotsits contain MSG?" doesn't offer a complete picture. It requires a closer look at specific product labels to identify the exact flavour enhancers used to achieve that signature umami taste.
The Case of Really Cheesy Wotsits
For many years, the classic Really Cheesy flavour has been the standard-bearer for the Wotsits brand. An examination of its ingredient list reveals the presence of a flavour enhancer, but it is not Monosodium Glutamate (MSG). Instead, the creamy, savoury flavour comes from Disodium 5'-Ribonucleotides, also known by its E-number E635. E635 is a mixture of two flavour-enhancing compounds, Disodium Inosinate (E631) and Disodium Guanylate (E627), and is often used alongside MSG for its synergistic effect, although it can be used on its own.
Do Flamin' Hot Wotsits Contain MSG?
In contrast to the cheesy version, some of the spicier Wotsits variants, such as the Flamin' Hot flavour, do contain MSG. The ingredients for these products often explicitly list "Monosodium Glutamate" or its E-number equivalent, "E621", alongside Disodium 5'-Ribonucleotide. This combination of enhancers works together to deliver a more complex and intense umami experience, enhancing the spicy and savoury notes of the snack.
The Umami Effect: MSG vs. Other Enhancers
MSG is a salt of glutamic acid, an amino acid found naturally in many foods like tomatoes and cheese. When added to food, MSG provides a powerful umami flavour, often described as meaty or savoury, that can be highly addictive to some palates. Other enhancers, like E635, don't necessarily have a strong umami flavour on their own but significantly amplify the impact of other flavours, including the natural glutamate present in ingredients. This is why E635 and MSG are often used in tandem, allowing manufacturers to use less MSG while still achieving a robust flavour profile.
Common Flavour Enhancers in Snacks
- Monosodium Glutamate (E621): The most well-known enhancer, prized for its strong umami flavour. Often used in savoury snacks, instant noodles, and processed meats.
- Disodium 5'-Ribonucleotides (E635): A powerful flavour intensifier that works synergistically with MSG. Often found in snack seasonings, packet soups, and sauces.
- Yeast Extract: A natural ingredient derived from yeast that contains high levels of naturally occurring glutamate. It is used to add a savoury umami flavour and sometimes replaces MSG in products marketed as 'no added MSG'.
Flavour Enhancer Comparison Table
| Feature | Monosodium Glutamate (MSG/E621) | Disodium 5'-Ribonucleotides (E635) | Yeast Extract |
|---|---|---|---|
| Primary Function | Provides a strong, direct umami taste. | Amplifies existing savoury flavours and has a synergistic effect with MSG. | Adds a rich, savoury umami flavour from natural glutamates. |
| Source | Produced via fermentation of carbohydrates (e.g., sugar cane, sugar beets). | Typically produced from dried fish or seaweed, or bacterial fermentation. | Derived from brewers' or bakers' yeast. |
| Use in Wotsits | Explicitly listed in some flavours like Flamin' Hot. | Found in many flavours, including the classic Really Cheesy. | Not typically the primary listed enhancer, but may be present in some seasonings. |
| Labelling | Must be declared as 'Flavour enhancer (MSG)' or 'Flavour enhancer (621)'. | Must be declared as 'Flavour enhancer (Disodium 5'-ribonucleotides)' or 'Flavour enhancer (635)'. | Can contain high levels of naturally occurring glutamate, but does not need to be labelled as MSG. |
| Synergy with MSG | Highly synergistic with E635, allowing for a more intense flavour with less product. | Works in conjunction with MSG to boost the umami flavour. | Can provide umami on its own, but also complements MSG. |
The Verdict: MSG's Role in Wotsits
The inclusion of MSG in Wotsits depends entirely on the specific flavour. The classic Really Cheesy flavour does not contain MSG, instead relying on E635. However, some variants like the Flamin' Hot flavour have MSG clearly listed on their ingredients. Both types of flavour enhancers are used to create the snack's highly palatable taste by activating umami receptors on the tongue, creating a moreish flavour experience.
Is MSG Safe to Eat?
Despite a lingering reputation from decades-old misinformation, major food safety organisations worldwide, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Association (EFSA), classify MSG as generally safe for consumption. The so-called "Chinese Restaurant Syndrome" has been largely debunked by multiple blinded studies. Only a very small subset of individuals might be sensitive to high, concentrated doses, but typical consumption levels pose no known risk to the general population. For those with sensitivities, reading the label is the most reliable method of avoidance.
Conclusion: Navigating the Ingredients List
So, do Wotsits contain MSG? The definitive answer is: it depends on the flavour. The classic Really Cheesy Wotsits use E635, while some other versions, such as Flamin' Hot, do include MSG (E621) as an ingredient. This variation highlights the importance of checking the nutritional information and ingredients list on every specific packet. The use of flavour enhancers is a standard practice in the snack food industry to create appealing, savoury tastes. For the vast majority of consumers, these additives are considered safe, though individuals with sensitivities should always exercise caution and consult product labels before consumption.
