What Is In Oxo Cubes? Exploring the Iconic Flavour Enhancer
Oxo cubes are a concentrated flavour enhancer, primarily composed of hydrolyzed vegetable protein, salt, and vegetable fat, alongside other ingredients that contribute to their distinctive flavour and aroma. These ingredients are compressed into a convenient cube shape for easy use in cooking.
A Brief History of Oxo
Oxo cubes have been a kitchen staple for generations, offering a convenient way to add depth and richness to soups, stews, and sauces. Initially developed as a beef extract, the Oxo brand has expanded to include a variety of flavours, catering to diverse culinary preferences. Their consistent flavour profile and ease of use have made them a favourite among both amateur and professional cooks. The journey of Oxo, from its initial conception to becoming a global culinary icon, is deeply intertwined with the evolution of convenient food solutions.
The Key Ingredients Explained
Understanding the individual components of Oxo cubes provides insight into their flavour-enhancing capabilities:
- Hydrolyzed Vegetable Protein (HVP): This is a key ingredient that provides umami, a savory flavour. It’s created by breaking down vegetable proteins into their constituent amino acids, primarily glutamic acid, which is responsible for that rich, savoury taste.
- Salt: A crucial component for flavour enhancement and preservation. Salt acts as a flavour carrier, intensifying other ingredients.
- Vegetable Fat: This adds richness and body to dishes. It also helps to bind the other ingredients together in the cube. Typically, palm oil or similar vegetable oils are used.
- Flavour Enhancers: Beyond HVP, additional enhancers, such as monosodium glutamate (MSG), may be present to further boost the umami flavour.
- Colour: Caramel colour is often used to give the cube its characteristic brown hue and contribute to the appearance of depth when dissolved in liquid.
- Onion Powder: Adds aroma and a subtle onion flavour, supplementing the overall savoury profile.
- Spices: A blend of spices (such as pepper, celery seed, or paprika) further layers the flavour, making it more complex and appealing.
- Yeast Extract: Contributes to the overall savoury notes, giving a deeper and more rounded flavour.
The Manufacturing Process
The production of Oxo cubes involves a carefully controlled process to ensure consistent flavour and quality:
- Mixing: All the ingredients, including HVP, salt, vegetable fat, flavour enhancers, colour, spices, onion powder, and yeast extract are thoroughly mixed in precise proportions.
- Heating: The mixture is then heated to melt the fats and blend all the flavours. This step is crucial for developing the distinctive Oxo aroma.
- Compression: The heated mixture is compressed into cube shapes using specialized machinery.
- Packaging: The cubes are then wrapped in foil or other protective packaging to maintain their freshness and prevent moisture absorption.
Nutritional Considerations
While Oxo cubes enhance flavour, they are also high in sodium. Therefore, it’s essential to use them sparingly, especially for individuals watching their salt intake. Check the nutritional information on the packaging for detailed information on sodium content and other nutrients. They are not a significant source of vitamins or minerals.
Common Misconceptions
A common misconception is that Oxo cubes are purely made from “beef” or “chicken”. While some varieties are flavoured accordingly, the base is primarily HVP and vegetable fat. It’s crucial to check the specific flavour and ingredient list on the packaging.
Alternatives and Substitutes
For those seeking alternatives to Oxo cubes, several options exist:
- Homemade Stock: Making your own stock from bones and vegetable scraps allows complete control over ingredients and sodium content.
- Bouillon Powder: These are similar to Oxo cubes but may have different flavour profiles and ingredient lists.
- Vegetable Broth: For a vegetarian option, vegetable broth can add flavour to dishes.
- Mushroom Powder: This is a natural way to add umami flavour.

Frequently Asked Questions About Oxo Cubes
What Exactly Does “Hydrolyzed Vegetable Protein” Mean?
Hydrolyzed Vegetable Protein (HVP) is a process where vegetable proteins are broken down into their amino acid components using acid, enzymes, or other methods. This process releases glutamic acid, which provides the umami, or savory, flavor that enhances the taste of food. The specific vegetables used to create HVP can vary.
Are Oxo Cubes Vegetarian?
The answer depends on the specific flavour. Some Oxo cubes, such as vegetable, are vegetarian-friendly. However, other flavours, like beef or chicken, contain animal-derived ingredients and are not suitable for vegetarians. Always check the product packaging to confirm.
Do Oxo Cubes Contain Gluten?
While Oxo cubes don’t inherently contain gluten from wheat, barley, or rye, it’s crucial to check the packaging for allergen information. Manufacturing processes can sometimes lead to cross-contamination, so those with gluten sensitivities should exercise caution and look for gluten-free labelled products.
What is the Shelf Life of Oxo Cubes?
Oxo cubes typically have a long shelf life, usually 12-18 months, when stored properly in a cool, dry place. Refer to the “best before” date printed on the packaging. While they may not spoil, the flavour may diminish over time.
Can I Eat Oxo Cubes Raw?
While technically safe to consume raw, eating Oxo cubes directly is not recommended. They are highly concentrated and very salty, making the experience unpleasant. They are intended to be dissolved in liquid and used as a flavour enhancer.
Are Oxo Cubes Suitable for Babies?
Oxo cubes are not recommended for babies due to their high salt content. Babies’ kidneys are not fully developed to process high levels of sodium. It’s best to use low-sodium or homemade alternatives when preparing food for infants.
How Much Oxo Cube Should I Use?
Generally, one Oxo cube is sufficient for about 500ml of liquid or a standard-sized pot of soup or stew. Adjust the amount based on your personal taste preferences and the desired intensity of flavour.
Can I Use Oxo Cubes in a Slow Cooker?
Yes, Oxo cubes are perfectly suitable for use in slow cookers. They dissolve slowly over the cooking time, gradually releasing their flavour into the dish. Add the cube(s) at the beginning of the cooking process for optimal results.
Do Oxo Cubes Contain MSG?
Some Oxo cube varieties do contain MSG (monosodium glutamate) as a flavour enhancer. If you are sensitive to MSG, check the ingredient list on the packaging before use. Some varieties are now MSG-free.
How Should I Store Oxo Cubes?
Store Oxo cubes in a cool, dry place away from direct sunlight. Keep them in their original packaging or an airtight container to prevent moisture absorption, which can affect their texture and flavour.
Can I Freeze Oxo Cubes?
Freezing Oxo cubes isn’t necessary because of their long shelf life, and it won’t affect their flavour or texture. However, if you’ve already dissolved an Oxo cube in a sauce or stock, it’s perfectly safe to freeze that liquid.
Are There Any Health Concerns Associated with Oxo Cubes?
The primary health concern associated with Oxo cubes is their high sodium content. Excessive sodium intake can contribute to high blood pressure and other health problems. Use them sparingly and be mindful of your overall sodium intake from other sources. Consult a healthcare professional or registered dietitian if you have concerns.
