No, Sensations Do Not Have Added MSG
One of the most persistent food myths is the idea that the intense flavor of certain snacks, like Sensations crisps, is due to added monosodium glutamate (MSG). However, a simple check of the product's official packaging and ingredient lists reveals this to be false. A statement on the packaging for flavors like Thai Sweet Chilli confirms that the crisps are made with "No Added MSG". The flavorful taste comes from a complex blend of spices, herbs, and other savory ingredients, not from the addition of this particular flavor enhancer.
Understanding the Ingredients
The ingredient list for Walkers Sensations Thai Sweet Chilli crisps, for example, shows a detailed breakdown of what makes up the snack's flavor profile. It includes sugar, soy sauce powder, fructose, hydrolyzed vegetable protein, and dried spices like onion, red chili flakes, and garlic. It's the savory notes from the soy sauce powder and hydrolyzed vegetable protein, which contain naturally occurring glutamates, that provide a rich, umami flavor. This is a crucial distinction, as naturally occurring glutamates and added MSG, while chemically similar, are perceived differently by many consumers.
Natural vs. Added MSG
The confusion around MSG and "sensations" is rooted in a larger misunderstanding about glutamates. Glutamate is an amino acid that occurs naturally in many foods.
Foods with Natural Glutamates
Foods rich in natural glutamates include:
- Parmesan cheese
- Dried mushrooms
- Ripe tomatoes
- Soy sauce
- Walnuts
These ingredients contribute to the savory, or umami, taste in dishes and are considered part of a healthy diet. Added MSG is the sodium salt of glutamic acid, and it is used commercially as a flavor enhancer. The human body processes both natural and added MSG in the same way, but some individuals report sensitivities to the added version. This perceived sensitivity is a significant part of the ongoing debate surrounding MSG, often fueled by anecdotal evidence rather than robust scientific data.
The Science of MSG Safety
Major health organizations, including the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO), classify MSG as "generally recognized as safe" (GRAS). Concerns about MSG first arose in the 1960s, leading to the term "Chinese Restaurant Syndrome" for symptoms like headaches, flushing, and tingling. However, subsequent blinded, controlled studies have largely failed to find a consistent link between MSG consumption and these symptoms in the general population. Any reported reactions are typically mild and temporary.
MSG and Food Sensitivities
While the vast majority of people can consume MSG without any issues, a very small percentage of the population may experience mild, short-term reactions. These reactions are not considered a true food allergy but are classified as an intolerance. The threshold for these reactions is often a high dose of MSG, consumed without other food, which is not typical of standard dietary intake. For those concerned about MSG intake, reading food labels is the most effective way to manage consumption.
Comparing Natural and Added Glutamates
| Feature | Natural Glutamates | Added MSG | What This Means for Sensations |
|---|---|---|---|
| Source | Found naturally in foods like cheese, tomatoes, and mushrooms. | Produced commercially for use as a food additive. | Sensations use ingredients with natural glutamates (e.g., soy sauce powder) but not added MSG. |
| Regulation | Not regulated as an additive; part of the food's natural makeup. | Regulated as a food additive by bodies like the FDA and must be labeled when added. | The "No Added MSG" label on Sensations packaging is a regulatory requirement and marketing promise. |
| Metabolism | Metabolized identically by the human body. | Metabolized identically to natural glutamate. | The body cannot tell the difference between the source of the glutamate once it has been digested. |
| Flavor | Creates the savory, umami taste. | Enhances the savory, umami taste. | Sensations achieve their rich flavor profile through a blend of natural ingredients, including those with natural glutamates. |
The Psychology of Food Perception
The expectation of a particular taste or sensation can significantly influence a person's experience. The powerful marketing and flavor profiles of brands like Sensations can create a perception of intense flavor that consumers might mistakenly attribute to MSG, especially given the history of misinformation surrounding the additive. This psychological phenomenon is known as the nocebo effect, where a person's negative expectations about a substance can lead to real, perceived symptoms. By providing a satisfyingly crunchy texture and a complex blend of herbs and spices, Sensations engages multiple senses, leading to a richer overall flavor experience.
Conclusion: No Added MSG, Just Good Flavor Chemistry
In conclusion, the answer to the question "Do Sensations have MSG?" is no, the popular crisps do not contain added monosodium glutamate. The brand explicitly states this on its packaging. The misconception likely stems from the intense umami flavor derived from naturally occurring glutamates present in other ingredients, such as soy sauce powder. Ultimately, the intense flavor profile is the result of careful seasoning and ingredient selection, not the controversial additive. Consumers can enjoy Sensations with the assurance that they are free from added MSG, and the richness they taste comes from a masterful combination of natural flavors.
