Abstract

This study was conducted to investigate the effect of medical herbs extracts on physicochemical characteristics of cooked rice. Three types (CLP 1, CLP 2, CLP 3) of extracts were prepared using 11 medicinal herbs, respectively. Polished rice was cooked with different concentration of medicinal herbs extracts by electric cooker. The moisture contents in cooked rice were decreased by increased concentration of herbs extracts, while total polyphenol contents were significantly increased. DPPH radical scavenging activities of cooked rice obviously were increased as herb extracts level increased. The consistency and setback value of the rice flour was reduced at all of the extracts, while breakdown and initial pasting temperature was increased. Color of cooked rice was shown different comparing to the control. However, the hardness, adhesiveness, springiness, cohesiveness and gumminess of cooked rice was increased depending on the concentration of extracts. These results showed that medicinal herbs extracts, which can benefit human health, is inducing the changes of physicochemical characteristics of cooked rice.
