The Complete Trader Joe’s Mayonnaise Guide: Real, Organic, and Vegan Tested
By Maya Lin-Takahashi
Q1: Does Trader Joe's mayonnaise contain added sugar?
A1: The standard Real Mayonnaise and Vegan Mayo Spread contain small amounts of cane sugar (less than 1 gram per serving) to round out the vinegar's acidity. The Organic Mayonnaise relies almost entirely on vinegar, lemon juice, and organic mustard flour for flavor, keeping residual sugars minimal.
Q2: Why does Trader Joe’s Organic Mayonnaise have a yellowish tint compared to the standard jar?
A2: The yellow color comes from two ingredients: organic egg yolks from pasture-managed hens and organic mustard flour. Conventional commercial spreads use bleached oils and omit mustard seed, creating a stark white appearance.
Q3: How long does an opened jar of Trader Joe's mayonnaise last in the refrigerator?
A3: Because Trader Joe’s avoids chemical preservatives like calcium disodium EDTA, opened jars should be stored in the coldest part of your refrigerator (not the door) and consumed within 6 to 8 weeks for optimal safety and texture.
Q4: Can Trader Joe's Vegan Mayo Spread be used as a 1:1 baking substitute?
A4: Yes. In chocolate cakes or quick breads where traditional mayonnaise is used to introduce moisture, the vegan spread functions as an effective 1:1 substitute. Its starch-and-oil matrix retains moisture throughout high-heat baking without altering final flavors.
