This study was conducted to investigate nutrition characteristics of the following major commercially available dried fish (MCDF) in South Korea: plain-dried fish [nogari (PD-N), Alaska pollock (PD-AP), red tongue sole (PD-RTS), and young tidepool gunnel (PD-YTG)], salt-dried fish [(yellow corvina (SD-YC) and red tilefish (SD-RT)], four types of boiled-dried anchovy of different sizes (BD-As), and freeze-dried fish [Pacific saury (FD-PS), Alaska pollock (FD-AP), and Katsuobushi]. The energy content of the MCDF ranged from 103.0 to 420.5 kcal per 100 g. The MCDF in nutritional and functional properties of minerals were SD-RT and Katsuobushi in calcium; none in phosphorus, sodium, or zinc; Katsuobushi in potassium and magnesium; PD-AP, SD-YC, and SD-RT in iron, PD-AP, PD-RTS, SD-YC, and SD-RT in copper; and PD-N, PD-AP, PD-RTS, SD-YC, SD-RT, FD-PS, FD-AP and Katsuobushi in manganese. The total amino acid content of the MCDF ranged from 15.85 to 71.96 g per 100 g; the major amino acids were glutamic acid, aspartic acid, lysine, and leucine. The fatty acid content of the MCDF ranged from 0.81 to 2.93 g per 100 g. The MCFSP expected in nutritional and functional properties of vitamins were PD-N, PD-RTS, FD-PS, FD-AP, and Katsuobushi in riboflavin; PD-N, PD-AP, PD-YTG, BD-As, FD-PS, FD-AP, and Katsuobushi in niacin; PD-N, PD-RTS, SD-YC, and BD-As in vitamin A; and PD-AP, PD-YTG, SD-YC, and FD-AP in vitamin E.

This study investigated the quality of noodles added with different amounts of freeze-dried fish scale collagen mixture powder (FDCMP). Freeze-dried fish scale collagen mixture was prepared by mixing ingredients (fish scale collagen : herb extracts : dextrin : distilled water=1:0.75:0.25:2), which were freeze-dried. Noodles were prepared by adding 0.5, 1.0, 1.5, and 2.0% (w/w) FDCMP based on flour weight. Cooked noodle weight and volume decreased with increasing amount of FDCMP, whereas turbidity of soups significantly increased. The water-binding capacity of FDCMP was higher than that of flour. Uncooked and cooked noodles showed reduced L values as well as increased a and b values increasing amount of FDCMP in the flour composite. Hardness and chewiness of cooked noodles significantly decreased with increased FDCMP content. Adhesiveness, cohesiveness, and gumminess increased with increased FDCMP content. Springiness and resilience were not significantly different between the control and FDCMP group. Finally, sensory evaluation results indicated that texture, mouthfeel, and overall preference of noodles containing 0.5% FDCMP were higher compared to those of the other samples. Based on cooking properties and sensory evaluation, freeze-dried fish scale collagen mixture powder up to 0.5% could be substituted for wheat flour to improve noodle quality.

Experiments were carried out to establish an effective artificial drying method of Pacific saury (Cololabis seira) to kwamaegi. Raw fish containing 67% moisture were dried up to containing less than 40% moisture by drying for 15 days. The fish lost moisture more rapidly during first 3 days of natural drying than artificial drying. Total lipid content increased from 16.1% to 30.3 and 29.8% by 15 days of natural and artificial drying, respectively. Neutral lipid occupying 91.63% of total lipid increased to 92~94% during 15 days of drying, while content of phospholipid and glycolipid decreased slightly. The values of peroxide and thiobarbituric acid increased up to 6 days of drying and then did not change. Peroxide levels were lower in artifically dried fish than in naturally dried ones.

The experiment was conducted to determine the value of black soldier fly (Hermetia illucens) larvae and pupae as feed supplements for fresh-water fish (Carassius auratus). Black soldier fly larvae grown on food waste were fed to fresh-water fish, live larvae alone, dried larvae, dried pupae and combination with commercial fish diet. A 16-week feed trial was conducted to determine whether black soldier fly larvae could be used as a feed supplement in fresh-water fish. The growth performance indicated that fish fed the live larvae ranked consistently higher, and in combination with commercial fish diet and dried larvae and pupae were next higher. The finding of this study suggest that black soldier fly larvae and pupae may be valuable feedstuff in commercial fish production.

The purpose of this study is to investigate the effect of ultra-fine powder kelp powder as a natural food additive for fast rehydration on the quality of freeze-dried fish cake noodle with soft and elastic texture properties during or after cooking. The average moisture content and water activity ranges of freeze-dried fish cake noodle were 3.71±0.12% (dry basis) and 0.185-0.332, respectively. The water activity of freeze-dried fish cake noodle decreased upon increasing the kelp powder content at the same moisture content. The rehydration ratios of fish cake noodle with 1, 3, and 5% (w/w) of kelp powder were 1.39, 1.49, and 1.77 g water/g solid, respectively. The hardness of the 5% (w/w) kelp powder-enhanced fish cake noodle after rehydration had the lowest value among the three samples upon using a texture profile analysis test (TPA). In the sensory hedonic test results, 5% (w/w) kelp powder added to fish cake noodle after rehydration produced the highest values in texture, flavor, and overall quality.

Objective: This study was to investigate the nutrient ileal digestibility of dried mealworm (Tenebrio molitor) larvae and compare with those of three animal protein by-products in growing pigs. Methods: A total of 12 crossbred ($[Landrace{\times}Yorkshire]{\times}Duroc$) growing pigs with average body weights of $24.12{\pm}0.68kg$ were surgically equipped with simple T-cannulas after being deprived of feed for 24 h according to published surgical procedures. These pigs had a recovery period of two weeks. A total of 12 pigs were assigned to individual metabolic crates and allotted to one of four treatments with 3 replicates in a fully randomized design. Dietary treatments included the following: i) Fish meal, corn-vegetable by-product basal diet+9.95% fish meal; ii) Meat meal, corn-vegetable by-product basal diet+9.95% meat meal; iii) Poultry meal, cornvegetable by-product basal diet+9.95% poultry meal; iv) Tenebrio molitor, corn-vegetable by-product basal diet+9.95% dried Tenebrio molitor larvae. Results: Results showed that the apparent ileal digestibility (AID) of Lys was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal diet. Pigs fed Tenebrio molitor diet showed increased (p<0.05) AID of His and Arg compared to pigs fed Fish meal or Meat meal diet. The AID of Cys was increased (p<0.05) in pigs fed poultry meal and Tenebrio molitor diets compared to that in pigs fish meal diet. Pigs fed meat meal, poultry meal, and Tenebrio molitor diets showed higher (p<0.05) standardized ileal digestibility (SID) of total energy compared to pigs fed fish meal diet. The SID of Arg was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal or meat meal diet. Furthermore, pigs fed poultry meal or Tenebrio molitor diets showed increased (p<0.05) SID of Cys compared to pigs fed fish meal diet. Conclusion: In conclusion, providing pigs with diets that contained Tenebrio molitor larvae meal improved AID and SID of nutrients as well as essential and non-essential amino acids. The digestibility of dried mealworm larvae protein and its utilization in vivo are also good. Therefore, dried mealworm larvae protein can be used as protein source at 10% level in growing pigs.

In this work, lipid oxidation and the kinetics of the oxidation reaction in fried file-fish meat were investigated when sun-dried file-fish was stored under the conditions of various water activities and temperature, 35, 45, 55 and $35/55^{\circ}C$. The storage stability and the development of browning by oxidative rancidity were also discussed. Monolayer coverage value of water content in dried file-fish was $8.03\%$ at $0.21\;a_w$Lipid oxidation at $35^{\circ}C$ was developed with increasing water activity but at $45^{\circ}C$and $55^{\circ}C$ it was rapidly progressed without clear differences between water activities except $0.44\;a_w$. The rate of reaction was more sensitive to storage temperature than to water activity. Browning in methanol-chloroform fraction was developed linearly by the progress of lipid oxidation which suggested that lipid oxidation was greatly influential to the development of browning in dried fish meat. In kinetical analysis the oxidation followed a zero order reaction mechanism as a function of carbonyl value. The activation energies obtained from the Arrhenius plot ranged 9.0 to 10.8 Kcal/mol and $Q_10$ values, 1.6-1.7. Shelf-lives at the storage of 35,45 and $55^{\circ}C$ ranged 58 days to 8 days. And in the fluctuating temperature storage at $35/55^{\circ}C$, shelf-lives were 17, 16, 15 and 13 days at 0.44, 0.52, 0.65 and $0.75\;a_w$, respectively. The shelf-lives for assessed from the accelerated shelf-life test were 125, 123, 120 and 106 days at 0.44, 0.52, 0.65 and $0.75\;a_w$, respectively, in the case of storage at $25^{\circ}C$.

The following is the test result of a clculation of the quantity of flavor content, that is, sixteen different kinds of free amino acid, found in both fresh and dried fish used widely as foodstuff here in Korea. 1. Throughout our test we were able to extract only a small amount of arginine though the amount of lysine, histidine, glycine, alanine and glutamic acid was comparatively large. 2. The test also showed that the amount of lysine decreased when a given fish dried up. The amount of methionine decreased in the case of Alaskan pollack though it increased in the case of Yellow corvenia. We also learned in our experiment that the amount of other flavor components increased though in varying degrees. 3. On the other hand, the content of free amino acid found in Yellow corvenia was much higher than in Alaskan pollack 4. And lastly, the test showed us that if and when the inflence of free amino acid is viewed strictly as a flavor-producing component, dried fish has much more flavor (and taste) than fresh fish.

Molecular techniques, including restriction fragment length polymorphism(RFLP) and polymerase chain reaction-single strand conformational polymorph isms(PCR-SSCP), were developed to identify salted, dried threadfin(Eleutheronema tetradactylum) and white herring(Ilisha elongata) fish. Using PCR with universal primers, conserved 367-bp fragments of the cytochrome b gene were amplified from fresh fish samples and sequenced. The sequences were then searched for specific restriction sites. The digestion of the PCR products with the endonucleases AvaI, FokI, MboII, and MspI generated RFLP, which was used to identify the commercial products. Similarly, the amplified PCR-SSCP products were developed and the products tested. Overall, similar patterns were found in the majority of the fresh and processed products. Based on the results, both RFLP and PCR-SSCP were useful in determining and validating the authenticity of the fish species used to prepare the commercial salted, dried products. A similar approach can be applied to other species.
