The effect of different ratios of Dory fish to tapioca flour on the linear expansion, oil absorption, colour and hardness of fish crackers

The objective of this study was to examine the effect of different ratios of fish to tapioca flour on the linear expansion, oil absorption, colour, and crispiness of fish crackers. Four different ratios of fish to tapioca flour were used in the formulation of the fish crackers. The results showed that protein and fat content increased with the increase in the ratio of the fish. On the other hand, linear expansion and oil absorption decreased with an increase in the ratio of the fish. Hardness also increased with the increase in the ratio of the fish. The colour measurement showed that the lightness value decreased with an increase in the ratio of fish and this decrease is seen more clearly with the fried fish crackers.
