Anthocyanins are a group of plant pigments that are widely distributed in nature , which are responsible forthe attractive colors of many flowers, fruits, grains and related products derived from them. Anthocyanins are valuable as kinds of important quality indicators in foods and chemotaxonomic indicators in plants. They attract much interest for its health function such as their potential antioxidant ability. Black rice (Oryza sativa L.) is a special cultivar of rice and widely consumed since ancient times in China and other Eastern Asia countries. It has been regarded as a health-promoting food for its abundant content of anthocyanins, but, anthocyanins are not stable and vulnerable to be destroyed by a number of factors such as: pH, light, oxygen, enzymes, ascorbic acid, thermal treatment, sulfur dioxide or sulfite salts, metal ions and copigments. Preventing anthocyanin degradation is an important aspect that can benefit both processors and consumers. Thermal degradation of anthocyanins is a major problem for the food industry. The composition and contents of anthocynins are different, and most studies are solely based on monitoring the absorption decrease. It's hard to predict the loss of each anthocyanin during heat process. To obtain further understanding of the thermal degradation of anthocyanins in black rice, it is necessary to investigate the degradation kinetics of each major anthocyanin, respectively. The first objective of this work was to identify the pigment composition of black rice using HPLC coupled to diode array detection and mass spectrometer (MS) detector. Secondly, investigate the effect of pH/temperature/time on each anthocyanin stability by creating a kinetic reaction model. The kinetic studies reported here could be useful in establishing appropriate processing.
