Is Real Mayonnaise Kosher?

The Ingredient Breakdown

When determining if a processed food like mayonnaise is kosher, we look at the source of every ingredient and the processing aids used. Real Mayonnaise relies on a classic emulsion formula that is naturally free of the most common kosher violators.

The primary fat source is SOYBEAN OIL. As a vegetable oil, it is inherently pareve (neither meat nor dairy). This is a crucial starting point because it avoids the strict separation required between meat and dairy products. The thickening agent comes from WHOLE EGGS and EGG YOLKS. While eggs are technically pareve, they do require checking for blood spots in strict kosher observance; however, commercially processed eggs are generally pre-checked by the manufacturer.

The acidity and preservation elements are DISTILLED VINEGAR, SALT, and LEMON JUICE. Distilled vinegar is acceptable provided it is not derived from wine (which is rare in American commercial vinegar). The remaining ingredients—SUGAR, NATURAL FLAVOR, PAPRIKA EXTRACT, and the preservative CALCIUM DISODIUM EDTA—are all synthetic or plant-derived additives that pose no kosher concerns. There is no hidden dairy in the 'natural flavor' or casein used here.

Nutritional Value

While Real Mayonnaise passes the kosher test, it is important to view it through a nutritional lens as well. The product is calorie-dense due to the SOYBEAN OIL, which constitutes the vast majority of the volume. A single tablespoon typically contains around 90 to 100 calories, almost entirely from fat.

Regarding carbohydrates, the SUGAR and CONCENTRATED LEMON JUICE contribute a negligible amount, making this a keto-friendly option in moderation. However, because it is high in fat, it should be consumed mindfully if you are monitoring your daily caloric intake. The CALCIUM DISODIUM EDTA is added strictly to prevent the oil from going rancid and has no caloric or nutritional impact.
