Effects of microwave cooking on the physicochemical and sensory properties of seaweed‐based analogue rice

Abstract

Summary Despite considerable progress in seaweed‐based analogue rice development, understanding the effects of cooking methods on its physicochemical and sensory properties is an essential area for further investigation. Therefore, this study aims to examine the effects of microwave cooking on the physical and sensory properties of seaweed‐based analogue rice. The experiment was carried out using various microwave power levels (180, 270 and 360 W) and heating duration (5 and 7 min). The optimal condition was achieved at 270 W for 7 min, leading to 94% water absorption, with L* , a * and b* values of 51.99, −0.75 and 8.09 respectively. The texture profile analysis showed hardness, springiness, cohesiveness, adhesiveness and chewiness of 10.52 N, 0.69 mm, 0.60, 71.30 g.s and 4.29 mJ respectively. The check‐all‐that‐apply sensory evaluation was also described the dominant sensory attributes of product. This method also demonstrated greater chemical compound and energy consumption when compared to conventional cooking methods. Eventually, this finding anticipates high rice demand and promotes seaweed‐based analogue rice as a new functional food with convenient cooking methods to address the growing need for efficient and time‐saving food preparation in modern lifestyles.
