  • To find the possibility in utilizing the fish meat processing by-products, protein nutritional quality and textural properties of crucian carp extraction residue (CCER, feeze dired) incorporated into cookies were investigated. Moisture, ash and protein contents in cookies were increased with the higher residue treatments, but lipid contents were similar within all levels (3%, 9% and 15%). Major constitutional amino acids were revealed as glutamic acid, proline, leucine and arginine, and the sum of those amino acids was about 50% of total amino acid contents. Cookies with residue (CCER) had higher (80.74~84.50%) in vitro protein digestibility than standard cookies (83.32%), while slightly lower trypsin indigestible substrate (TIS) contents were showed in CCER containing cookies than control. CCER treatments resulted the decreased protein nutritional quality in C-PER (computed protein efficiency ratio) value from 2.41 (standard) to 1.15 (cinnamon flavored. 9% CCER), and those C-PER of all cookies were lower than ANRC casein (2.50). Lipophilic browning was developed steadily till 60 days storage and a significant (p<0.05) changes of browning ws not noteed between 60 days and 90 days storage. Color of cookies, expressed as L, a and b value, was significantly (p<0.05) lightened with the increased CCER. Similar trends by treatments were noted for hardness. Cookies containing 9% CCER were similar to control regarding textual and sensory properties.

  • The know the possibility in development of the low-fat beef patty models using crucian carp9 extraction residues (CCER, freeze dried powder : 5%, 10%, 15%), those protein nutritional quality, texture, color and sensory properties were investigated. About 13∼23% (on dry basis) of lipid in control was reduced in cooked beef patties with the higher addition ratios of CCER. In vitro protein digestibility was not changed in raw patties before cooking but 2∼4% higher digestibility was revealed in cooked patties. Computed protein efficiency ratio (C-PER) and discriminant computed protein efficiency ratio (DC-PER) of beef patties containing CCER were almost same as control. Lightness and red color value of both (raw and cooked) beef patties were decreased with the higher CCER addition ratios but brown color value of cooked samples were similar to control. Stronger hardness was noted in all beef patties containing CCER significantly (p<0.05). Consumer's acceptability were generally decreased by addition of CCER, but 10% level could be recommendable in beef patty processing.
