Is Sargento Colby-Jack cheese Gluten Free?

The Ingredient Breakdown

When investigating whether a processed food is safe for a gluten-free diet, the complexity of the ingredient list is usually the first red flag. Fortunately, Sargento Colby-Jack keeps it incredibly simple. The product contains: Pasteurized milk, cheese culture, salt, enzymes, and annatto (vegetable color).

Let's look at why these are safe. Pasteurized milk and cheese culture are dairy derivatives, which are naturally free of gluten. Salt is a mineral, and enzymes (specifically microbial rennet) are used to coagulate the milk; they are not derived from wheat, barley, or rye. The only ingredient that requires a second look is annatto. Annatto is a natural food coloring derived from the seeds of the achiote tree. While natural colorings are sometimes processed using grain-based alcohols, annatto is universally recognized as safe for gluten-free diets because it is plant-derived and not associated with gluten cross-contamination in this context.

The most critical factor here is the absence of 'natural flavors' or 'modified food starch,' which are common hiding spots for gluten. Because Sargento uses a dedicated facility and transparent labeling, this specific blend poses no gluten risk.

Nutritional Value

From a nutritional standpoint, Sargento Colby-Jack is a standard full-fat dairy product. A standard serving (approx. 1 oz) typically contains around 100 calories, with 8 grams of fat (5g saturated) and 6 grams of protein. It is a source of calcium and phosphorus, essential for bone health.

For those on a ketogenic or low-carb diet, this cheese is an excellent option as it contains zero carbohydrates and zero sugar. However, because it is a full-fat dairy product, it is calorie-dense. If you are strictly monitoring your sodium intake, note that cheese naturally contains salt, so portion control is advised. It fits well into a balanced diet but should be consumed in moderation alongside whole foods.
