While many people refer to the product as Imperial margarine, it is technically a "vegetable oil spread" under U.S. FDA regulations due to its fat content being less than the 80% required for margarine. The ingredients can vary slightly depending on whether the product is in stick or tub form, but the core components remain consistent. The primary components are a blend of vegetable oils, water, and salt, which form a stable emulsion with the help of emulsifiers. These are supplemented with preservatives, flavorings, and vitamins to create the final product.
The Vegetable Oil Blend
At the heart of Imperial's formula is its vegetable oil blend. This mix is what gives the spread its structure, texture, and fat content.
- Soybean Oil: A common vegetable oil known for its neutral flavor profile and versatility in cooking.
- Palm Oil: A solid fat at room temperature, which is crucial for giving the spread a firm, stick-like consistency.
- Palm Kernel Oil: Another solid fat derived from the palm fruit, used alongside palm oil to improve the overall texture and firmness.
Water and Emulsifiers
To create a spreadable product, the liquid vegetable oils must be combined with water in a stable mixture called an emulsion. This is achieved with the help of several key ingredients.
Emulsifiers and Stabilizers
- Distilled Monoglycerides: These are fats that act as emulsifiers, helping to blend the oil and water components uniformly.
- Soy Lecithin: Another emulsifier that helps to stabilize the oil-water mixture and ensures a smooth, consistent texture.
Preservatives and Acidity Regulators
To maintain its quality and prolong its shelf life, Imperial contains several preservatives and acidity regulators.
- Potassium Sorbate: A common food preservative used to inhibit the growth of mold, yeast, and certain bacteria.
- Calcium Disodium EDTA: An agent used to protect the quality and freshness of the product by preventing spoilage.
- Citric Acid: An acidity regulator that adds a tart flavor note and acts as a preservative.
Flavor and Color
These additives are responsible for the spread's taste and appearance, mimicking that of traditional butter.
- Natural and Artificial Flavors: These are included to give Imperial its signature buttery flavor.
- Beta Carotene: A natural pigment that provides the yellow color associated with butter.
- Vitamin A Palmitate: This is added to fortify the product with vitamin A.
Comparing Imperial Spread and Butter
| Feature | Imperial Vegetable Oil Spread (Sticks) | Traditional Butter |
|---|---|---|
| Core Ingredients | Vegetable oil blend (soybean, palm, palm kernel), water, salt. | Dairy cream. |
| Fat Content | 50% vegetable oil. | 80% milkfat. |
| Source | Plant-based vegetable oils. | Animal-based (dairy). |
| Lactose | Generally lactose-free; stick version contains whey, but lactose-free options exist. | Contains lactose. |
| Cholesterol | 0 mg. | Contains cholesterol (approx. 30 mg per tbsp). |
| Melting Point | Higher melting temperature, resulting in slower melting. | Lower melting temperature, melts easily. |
| Best For | Baking, spreading (yields chewier baked goods). | General cooking, baking, richer flavor. |
Ingredient Variations
It is important to note that the ingredient lists can differ between the stick and tub varieties of Imperial spread. The sticks often contain different additives to achieve a firmer consistency for baking. For instance, some stick versions may contain Pea Protein for added stability. Conversely, tub spreads sometimes list Vinegar as an ingredient, which is not found in the sticks. Always check the label of the specific product you are purchasing to confirm the ingredients. Upfield, the parent company, also offers lactose-free and plant-based versions, further highlighting the potential for variation within the brand's product lineup.
Conclusion
Imperial margarine is a vegetable oil spread with a clear and consistent ingredient profile centered around a blend of vegetable oils, water, salt, and various additives for emulsification, preservation, and flavor. While often used interchangeably with butter in recipes, its composition differs significantly, particularly in its fat source and dairy content. It remains a popular, affordable, and versatile alternative to butter, especially for baking and spreading, though consumers with dietary restrictions should always verify the specific product's label for accuracy.
