Tag: Natural indicator

Most people assume that turmeric is acidic, but its primary compound, curcumin, is actually a natural pH indicator that turns reddish-brown in basic solutions. This article will delve into the specific chemical compounds, including what kind of acid is found in turmeric, that contribute to its well-known properties and nutritional profile.

While solid turmeric powder has no measurable pH, a solution of turmeric extract dissolved in water is typically found to be slightly acidic, with some research indicating a pH of around 5.90. This initial finding, however, does not fully answer the complex question of whether turmeric is alkaline or acidic, which depends on its active compounds and how it reacts with other substances.
