Study on the Micronutrients Fe,Zn,Cu and Pigment in Black Rice

Abstract

Abstract: The content and distribution of microelements, Fe、 Zn、 Cu in black rice and the effect of light. Temperature and some common metal ions on the stability of black rice pigment were declared, Determination indicated that the content of Fe and Zn in black rice were 386 10-6 and 360 10-6 respectively and concentrated in the pigment, while the content of Cu was Less than 10 10-6. The influence of light against stability of the pigment increased in accordance with The duration of exposed time. Fe2+、 Fe3+、 and Sn2+ strongly influence the pigment stability.

Key words: , Microelement Black Rice Black Pigment Stability；
