Supermarket miso tests reveal expensive products often contain additives and preservatives
A taste test of supermarket miso pastes found that the least authentic products were among the most expensive while containing synthetic ingredients.

High cost does not guarantee quality
The evaluation showed that the least authentic and most processed products in the test were also some of the most expensive. These items are described as synthetic imitations cut with thickeners, colourants, acidulants and preservatives rather than traditional fermentation methods.
Best overall choice identified
Hikari Maru-Yu additive-free koji miso received the top rating for its rich aroma and simple recipe. This paste features a granular texture and is made without additives to maintain traditional flavour profiles.
Value option highlighted
Yutaka organic miso paste was named the best bargain due to its incredible value and smooth texture. The product contains a simple formula of soya beans, rice and salt while earning a Great Taste award in 2024.
