Abstract

A study was carried out to establish a detection method for irradiated black pepper using amylograph characteristics. The maximum viscosity, viscosity at $93^{\circ}C$, viscosity after 15 min at $93^{\circ}C$, viscosity at $45^{\circ}C$, viscosity after 30 min at $45^{\circ}C$, and viscosity after 60 min at $45^{\circ}C$ decreased with increasing irradiation doses, but initial pasting temperatures, maximum viscosity temperatures, breakdown, setback, and consistency did not show great changes. The high correlation coefficients $(R^2>0.97)$ were shown between irradiation doses and amylograph characteristics except for breakdown $(R^2>0.75)$, setback $(R^2>0.88)$ and consistency $(R^2>0.31)$. These results suggest that detection of irradiated black pepper is possible using amylograph characteristics.
