Kajian Pengolahan Kwetiau Konsentrat Protein Ikan Gabus (Channa Striatus) Yang Difortifikasi Tepung Karagenan
ABSTRACT
The research aimed to determine the effect of addition of flour carrageenan at different
concentrations on the quality of kwetiau made from the snakehead fish protein concentrate. The
research used an experimental method and composed as a non-factorial Completely Randomized
Design (CRD). The treatment conducted was addition of carrageenan flour varied in 4
concentrations (0, 2, 6, and 10 %). The results showed that the addition of carrageenan flour was
affecting significantly to the snakehead fish protein concentrate kwetiau produced that was
evaluated by the different sensory value of the taste, aroma, and texture value; folding test,
moisture content, protein content, and ash content; and elongation value. The best kwetiau
produced was indicated by the addition of carrageenan flour at a concentration of 2%. This
product was characterized by the higest value of appearance on 7.3 (whole, slightly brownish
white), aroma on 6.4 (a little seaweed aroma), taste on 6.7 (slightly tasted seaweed), and texture
on 7.7 (chewy and soft). The value of folding test was 8.0 (not cracked when folded one) and the
elongation value was 26.48. The content of ash was 2.20 %, protein was 18.68 %, and water was
68.11%.
