This study showed the optimum conditions for producing rice extrudate added with the sea tangle powder, and presented the effects of moisture content, barrel temperature and the amount of sea tangle powder. From the results, the more the amount of sea tangle powder was added, the less the water absorption ratio was showed, while the more the texture became smooth, the more the expansion ratio increased. From the sensory evaluation, the best preference was obtained when the moisture content was $18\%$, and the barrel temperature was at $100^{\circ}C$. Between control and $10\%$ sea tangle, there was no significant difference in all observed parameters. But if more than $20\%$ sea tangle was added, low sensory evaluation scores were obtained due to the peculiar smell from sea tangle. From these results, addition of sea tangle below $10\%$(w/w) did not affect the quality of products.
