Copied from the official site as of the date checked. The label is shown in Japanese as printed; tap an ingredient to see its English name and role. The links in the table below lead to our Ingredients A–Z and food additive database. The ingredient list, allergens and nutrition facts were copied from the product page on Kewpie’s official site (not from a photo of the package). The official page says “本品はアレルゲンとして卵白を含みます” (this product contains egg white as an allergen) and “卵は低温殺菌していますが、アレルゲン性は生卵と同等とお考えください” (the eggs are low-temperature pasteurized, but please consider the allergenicity the same as raw eggs). After opening, refrigerate (1–10°C) and eat within about 1 month, it says.
Ingredients, one by one
| On the label | Type | Role | Notes |
|---|---|---|---|
| 食用植物油脂（国内製造）edible vegetable fats and oils | Ingredient | Main ingredient (oil) | Ingredients are listed from the largest amount to the smallest, so oil is the biggest part. The official site’s “原料” (ingredients) page describes it as a blend of vegetable oils such as rapeseed and soybean oil. “国内製造” (made in Japan) means the oil was made in Japan; it is not where the raw materials come from. |
| 卵黄egg yolk | Ingredient | Emulsifying (binds oil and vinegar); richness | The label uses only the yolk. The official site explains that 3.6 egg yolks are used in 450 g of mayonnaise. |
| 醸造酢brewed vinegar | Ingredient | Sourness; keeping quality | The official site describes it as vinegar made specially for mayonnaise from raw materials such as apple juice and malt. The allergen label “りんご” (apple) appears to refer to this (not checked against the manufacturer’s materials). |
| 食塩salt | Ingredient | Saltiness; keeping quality | — |
| 香辛料spices | Ingredient | Flavor | The label does not say which kinds. |
| 調味料（アミノ酸）seasoning (amino acids) | Food additive | Umami | An umami additive such as monosodium glutamate. “調味料” (seasoning) is a group name, and the rules allow it to be written together rather than as individual substance names. “アミノ酸” (amino acids) alone in the parentheses, without “等” (etc.), means only seasonings from the amino acid group are used. |
| 香辛料抽出物spice extract | Food additive | Flavor | Aroma and pungent components taken out of spices. It is treated as an additive (an existing additive, “既存添加物”), separate from the food “香辛料” (spices). The label does not show which spices. |
