Is Blue plate mayonnaise Kosher?

The Ingredient Breakdown

When determining if a product is Kosher, we look at the source of every single ingredient. For Blue Plate Mayonnaise, the verdict is straightforward because the formula relies on plant-based fats and standard emulsifiers. The primary ingredient is soybean oil, which is inherently Kosher (Pareve) as it comes from a vegetable source.

The acidity comes from distilled vinegar. In the world of food science, distilled vinegar is chemically pure acetic acid and water; the original source (often corn or grain) is removed during the distillation process. Therefore, it is universally accepted as Kosher. The emulsifier is egg yolks. Like the oil, eggs are Pareve, meaning they contain no meat or dairy properties, making them compatible with a Kosher diet.

We also see calcium disodium EDTA listed as a preservative to protect quality. This is a synthetic antioxidant that prevents the oils from going rancid. It is a laboratory-synthesized ingredient that contains no animal derivatives. Finally, the natural flavor is a common point of concern, but in the context of mayonnaise, this is typically derived from vegetable sources or spices to enhance the savory profile. With no meat, dairy, or shellfish derivatives present, the formula passes the ingredient test.

Nutritional Value

While being Kosher makes it permissible, it is also important to consider how this product fits into a healthy diet. Blue Plate Mayonnaise is a calorie-dense food, primarily due to the high concentration of soybean oil. A standard serving contains a significant amount of fat, which is expected for a traditional mayonnaise recipe. However, because it uses soybean oil rather than animal fats like lard, it remains a cholesterol-free option (assuming the egg yolks are used in a ratio that keeps cholesterol low or the product is fortified).

The sugar content is relatively low compared to sweetened condiments like ketchup, but it does contribute to the overall calorie count. For those monitoring their sodium intake, the salt content is moderate. If you are following a strict Keto or low-carb diet, this product generally fits within the macronutrient limits, provided you track your serving sizes carefully. It is a high-fat, low-carb condiment, but it should be consumed in moderation due to the high caloric density of the oil.
