Abstract
This study investigated the quality, sensory characteristics, and commercialization potential of a rice snack made from dried anchovy Engraulis japonicus. Mild and spicy snacks were produced using a single extruder, with an oil coating or seasoning, respectively. The approximate respective compositions of the mild and spicy snacks were as follows: moisture 5.20% and 4.71%; crude protein 8.71% and 8.59%: crude lipids 21.14% and 28.5%; ash 1.57% and 1.82%; salt 1.5% and 1.5%; water activity 0.18 and 0.19; and pH 6.31 and 6.28. The peroxide values increased for 30 days after preparation and then decreased from 30 to 90 days. The thiobarbituric acid values increased slightly during storage at <TEX>$27{\pm}2^{\circ}C$</TEX>. During storage at <TEX>$27{\pm}2^{\circ}C$</TEX>, the lightness and yellowness values were lower for the spicy snack than for the mild snack, while the redness value was higher for the spicy snack. The hardness values of both samples decreased slightly during storage at <TEX>$27{\pm}2^{\circ}C$</TEX>. The sensory score of the spicy snack was slightly higher than that of the mild snack. The spicy snack had a higher score than the mild snack in the sensory test, which suggested that the spicy snack made from dried anchovy has more commercial potential.
