Frequently asked
FAQ
If a chip has E627, is it vegan?
You must check the allergy label. If the product contains a 'Fish' allergy warning, the E627 is likely fish-derived. If not, it is usually vegan, but checking with the brand is safest.
Why is it always paired with MSG?
Disodium guanylate and MSG have a synergistic effect. When combined, they create an umami flavor that is significantly stronger than either ingredient alone.
