Why Kewpie Mayonnaise Is Safe
When you pick up a bottle of Kewpie mayonnaise from a store shelf, you can be confident in its safety. The Kewpie corporation has confirmed that all the eggs used in its mayonnaise products are pasteurized, a heat-treatment process that effectively kills any potentially harmful bacteria, such as Salmonella. This manufacturing step aligns with food safety regulations in most countries and addresses concerns about consuming products with raw eggs.
The Pasteurization Process
For commercial producers like Kewpie, pasteurization is a non-negotiable part of the production line. This process typically involves heating the egg product to a specific temperature for a set amount of time. While the exact methods are proprietary, Kewpie Malaysia, for example, specifies heating eggs to 68 degrees Celsius to ensure safety. This heat treatment is critical because while homemade mayonnaise recipes often call for raw eggs, commercial versions must meet stringent safety standards to be shelf-stable before opening.
Flavor Profile and Ingredient Differences
Kewpie mayonnaise is celebrated for its unique flavor and texture, which sets it apart from traditional American mayonnaise. These differences are primarily due to a few key ingredients and how they are processed. The manufacturer uses only egg yolks, rather than the whole egg, resulting in a richer, creamier texture and a deeper yellow color. The company also develops its own proprietary blend of vinegars, which includes a mix of rice, apple cider, and distilled vinegars, to achieve its signature tangy and slightly sweet flavor.
Key Ingredient Differences
- Egg content: American mayonnaise uses whole eggs (yolks and whites), while Kewpie uses only egg yolks, resulting in a richer product.
- Vinegar blend: American brands typically use distilled white vinegar, whereas Kewpie uses a more complex and milder blend of vinegars.
- Umami flavor: Authentic Japanese Kewpie contains MSG for a savory umami boost, though the U.S. version uses yeast extract instead.
- Preservatives: Kewpie relies on the natural preservative qualities of vinegar and salt, using no added chemical preservatives.
How Kewpie's Manufacturing Ensures Quality
The Kewpie company has stringent quality control measures to ensure product safety and quality. Their process is more than just pasteurization; it’s a comprehensive approach to food science.
- Microbiological Assessment: Kewpie's Food Safety Science Center continually tests raw materials and finished products to prevent microbial contamination.
- Proprietary Emulsification: The exceptionally smooth and velvety mouthfeel of Kewpie mayo is achieved through proprietary emulsification machinery, which blends the ingredients into a perfectly glossy texture.
- Oxygen-Proof Packaging: Kewpie's signature squeezable bottle is made from multi-layered plastic designed to keep oxygen out, which helps maintain freshness and flavor without needing extra chemical preservatives.
