Abstract

Abstract:

In order to avoid food poisoning for eating nitrite by mistake, Monascus pigment staining was used to provide a warning method for nitrite in food. Monascus pigments and sodium nitrite were homogeneously blended in three different ratios (1:10000, 5:10000 and 10:10000, m/m), and the effects of direct sunlight, illumination light (in a place free from direct sunlight), darkness, temperature, pH and sodium chloride on the stability of the resulting staining products. The staining product with 1:10000 Monascus pigments/sodium nitrite ratio presented the best stability in the dark, and the storage condition for stabilizing the staining product with 5:10000 Monascus pigments/sodium nitrite ratio (m/m) best was free from direct sunlight.

Key words: nitrite, warn, monascus pigment, stability
