Decoding the ingredients in processed cheese
For many, processed cheese slices are a staple for sandwiches and burgers. However, for those on a vegetarian diet or with other dietary concerns, a key question arises: 'Does Kraft cheese contain gelatin?' The answer is not a simple yes or no, as it depends on the specific product and its formulation. Gelatin is a texturizing agent derived from animal collagen, commonly from pig skin, cattle hides, or bones. Its use in food manufacturing is widespread, particularly in desserts, candies, and some dairy items to improve texture and stability.
For example, archived ingredient lists for some Kraft American Cheese Slices with 2% milk show gelatin included in the ingredients, listed among stabilizers and coloring agents. In contrast, other Kraft Singles American Cheese Slices have ingredient lists that omit gelatin and instead rely on other additives like modified food starch for texture. This highlights the importance of checking each product individually, as formulations can differ based on product line, fat content, and regional recipes. Newer formulations and international markets, for instance, might use different gelling agents.
The role of enzymes and additives
Understanding the cheesemaking process is key to differentiating between different dairy products. Traditional cheese uses rennet, a complex of enzymes that coagulates milk. Historically, this rennet was sourced from the stomachs of young calves, but modern cheesemaking frequently uses microbial or plant-based rennet, which is suitable for vegetarians. Processed cheese, however, is a different category altogether. It involves blending natural cheeses and other ingredients, often with the addition of emulsifying salts and stabilizers to create a uniform, meltable product.
In processed cheese, gelatin's function is to stabilize the emulsion, prevent phase separation, and create a smooth, consistent texture. In recent years, due to increased consumer demand for vegetarian products, many manufacturers have shifted towards plant-based or synthetic alternatives. Common vegetarian thickeners and stabilizers include carrageenan, cellulose gum, and modified food starch.
Gelatin vs. other gelling agents
For a consumer, distinguishing between different gelling agents is vital for adhering to dietary standards. The ingredient label is the most reliable source of information. While gelatin is always listed by name, other ingredients like "enzymes" can be ambiguous. In the U.S., cheese labels that simply list "enzymes" may be using either animal or microbial rennet, so contacting the manufacturer is often necessary for confirmation.
Here is a comparison of common gelling and stabilizing agents found in dairy products:
| Feature | Gelatin | Microbial Rennet | Modified Food Starch | Carrageenan |
|---|---|---|---|---|
| Source | Animal collagen (e.g., pig, cow) | Microorganisms (e.g., fungus) | Plants (e.g., corn, potato) | Red seaweed |
| Dietary Status | Not vegetarian or vegan | Vegetarian (microbial) | Vegetarian and vegan | Vegetarian and vegan |
| Function | Gelling agent, stabilizer, texturizer | Coagulates milk to form curds | Thickener, stabilizer | Stabilizer, emulsifier |
| Use in Cheese | Stabilizer in some processed varieties | Curdling agent for many cheeses | Thickener in processed cheese | Used in some dairy products |
| Labeling | Explicitly listed as 'gelatin' | May be listed as 'microbial enzymes' or simply 'enzymes' | Listed as 'modified food starch' | Listed as 'carrageenan' |
The nutritional aspects of cheese consumption
Moving beyond additives, a balanced nutrition diet incorporates an understanding of the product's overall composition. Traditional, unprocessed cheese can be a good source of protein and calcium. However, highly processed cheese products, like some Kraft varieties, often contain additional salts, stabilizers, and colors. These additions can influence the nutritional profile, with some processed options having higher sodium content.
When evaluating cheese for a healthy diet, it's wise to consider the level of processing. Many cheese alternatives and specific product lines, such as Kraft's newer plant-based offerings developed in partnership with NotCo, are now available for vegans and those seeking dairy-free options. These products use completely different ingredients, often based on plant proteins and fats, to mimic the taste and texture of cheese.
Conclusion
The question of whether Kraft cheese contains gelatin has no single answer and requires a careful reading of the ingredient label. Historically, some varieties of processed cheese slices have used gelatin as a stabilizer. However, with evolving recipes and market demands, many processed cheeses and their plant-based alternatives now rely on microbial or plant-derived additives. For consumers following a vegetarian or vegan nutrition diet, or simply aiming for less processed food, reviewing the product's specific ingredient list is the most reliable way to make an informed choice. It is a clear reminder that not all cheese is created equal, especially when moving from traditional dairy to processed products and their plant-based counterparts.

Key takeaways
- Check the Label: Some Kraft products, like certain 2% milk American cheese slices, have contained gelatin in the past. The specific product's ingredient list is the only reliable source.
- Gelatin's Role: In processed cheese, gelatin primarily serves as a stabilizer and texturizer, giving the product a consistent and smooth feel.
- Vegetarian Alternatives: For those avoiding gelatin, many processed cheese products use vegetarian-friendly stabilizers like modified food starch, carrageenan, or cellulose gum.
- Not All Cheeses Are Created Equal: Regular cheese uses rennet, which can be animal-derived, but many modern cheeses use microbial or vegetable rennet. Processed cheese, however, is a different category altogether.
- Vegan Options Exist: Kraft and other brands now offer plant-based, dairy-free, and vegan alternatives that do not contain animal-derived ingredients.
- Formulations Change: Recipes can vary by product line and over time, so relying on general knowledge is insufficient. Always read the label for the most current information.
- Beware of 'Enzymes': For some cheeses, the term "enzymes" on a label can be non-specific. If you want to avoid animal rennet, look for products explicitly labeled with "microbial" or "vegetarian" enzymes.
