Premature-green rice is typically obtained by early harvest when culms of rice still appear green in color, and the rice and its food products have been considered as wellbeing foods. This study was carried out to determine the quality characteristics of cookies made from flour added with 10, 20, and 30% whole green rice powde r(WGRP) of two kinds of Hopum and Shinsun waxy rice. The quality characteristics of cookies, including pH, spread factor, color, hardness, and sensory properties, were estimated. WGRP with different levels of 10, 20, and 30% was added into powder for preparing cookies, and their quality properties were evaluated. The pH and hardness of the cookies increased, while spread factor showed highest added with 20% Hopum and Shinsun waxy rice. The color (L) of cookies decreased 20% added with Hopum and Shinsun waxy rice. The sensory properties of cookies was highest added with 20% Hopum and 10% Shinsun waxy rice. The result of this study suggest that addition of 20% Hopum and 10% Shinsun waxy rice are available rice cookies. It was concluded that WGRP may have a potential in bakery industry as a new food material.
