  • This study investigated proximate compositions and quality characteristics of wet noodles with the addition of freeze dried garlic powders prepared at 0.5, 1.0, 2.0, and 4.0% based on flour source, respectively. The moisture, crude protein, crude fat, nitrogen free extract, crude fiber, and crude ash of the freeze dried garlic powder were $4.72{\pm}0.14%,\;19.46{\pm}0.28%,\;1.21{\pm}0.10%,\;68.45{\pm}2.06%,\;2.38{\pm}0.05%,\;and\;3.78{\pm}0.06%$, respectively. The cooked weight, volume, water absorption of cooked noodles were decreased, but the turbidity of soup was increased with the addition of garlic powder. Increased of L (lightness), a (redness) and b (yellowness) values were caused as the amount of garlic powder increased in dough. Decrease of L value and increase of a and b value were shown with the increase of garlic powder in cooked noodle. The cooked noodles with garlic powder were significantly lower in hardness, adhesiveness, springiness chewiness, gumminess and cohesiveness than those of 100% wheat noodle. Sensory evaluation indicated that cooked noodles with 0.5% garlic powder was not significantly different from the control.

  • An 18-week growth trial was conducted in flow-through aquarium system to evaluate the practical dietary protein sources for juvenile abalone (Haliotis discus hannai). Three replicate groups of the abalone averaging 0.11g were fed one of ten diets containing casein, white fish meal (WFM), meat meal (MM), feather meal (FM), blood meal (BM), soybean meal (SM), corn gluten meal (CGM), cotton seed meal (CSM), Undaria powder (UP), or wheat flour (WF) as a dietary protein source. In addition, these dietary protein sources were cmpared with algae such as raw Undaria or dried Laminaria. Weight gain of abalone fed the diets containing casein, WFM, SM, CSM, or UP was significantly higher (P<0.05) than those of abalone fed other diets, and this value of abalone fed FM, BM, CGM, or algae was lower than other groups. Shell length, shell width, body wt./shell length ratio, and body wt./shell width ratio of abalone fed casein, WFM, SM, CSM, UP, and WF were also highe (P<0.05) than those of other groups. There were no significant difference (P>0.05) in moisture and protein contents of soft body among all diets. The data obtained in this study indicate that each of the casein, WFM, SM, CSM or UP is good dietary protein source for juvenile abalone.

  • This study evaluated the qualitative properties of Buchimgaru supplemented with JAP (Jerusalem Artichoke Powder). In Buchimgaru, JAP and wheat flour were mixed in ratios of 1:9 (10% JAP), 2:8 (20% JAP), and 3:7 (30% JAP). The values for texture profiles (hardness, chewiness, springiness, and cohesiveness) decreased when JAP was added to Buchimgae formulations. The fructan contents of Buchimgaru supplemented with 0, 10, 20, and 30% JAP were 1.52, 6.39, 10.50, and 13.71%, respectively. The total polyphenol content of Buchimgaru supplemented with JAP was significantly higher than Buchimgaru without JAP. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of Buchimgaru supplemented with 30% JAP was approximately 11 times greater than Buchimgaru without JAP. In the sensory evaluation (color, flavor, overall preference), Buchimgae supplemented with JAP showed higher sensory values than Buchimgae without JAP.

  • This study was performed to determine effects of dietary inclusion of various concentrations and sources of sea tangle Laminaria japonica on growth, body composition and plasma chemistry of juvenile black porgy Acanthopagrus schlegeli. Juvenile fish (N=810; average mass=8.9 g) were distributed among twenty-seven 200 L flow-through tanks (30 fish per tank). Nine experimental diets were prepared: control (Con) without additives; sea tangle powder at 0.1%, 0.5%, 1%, 2%, 3% and 5%, (P-0.1, P-0.5, P-1, P-3 and P-5 diets, respectively); and fresh sea tangle (F-1); and 1% sea tangle extract (E-1). Each powdered additive was substituted for an eqaul amount of wheat flour, and the extract was substituted for an equal amount of water in the respective experiemtnal diets. Each diet was fed to triplicate groups of fish. Weight gain and feed conversion ratio were not affected by the experimental diets. Feed consumption by fish fed the P-1 diet was higher than that of fish fed the P-3 and P-5 diets. Moisture, crude protein, crude lipid, whole-body ash content (excluding the liver), liver moisture, and crude protein and lipid contents of fish were not affected by the experimental diets. None of the fish plasma criteria were affected by the experimental diets, with the exception of plasma glucose. In conclusion, dietary inclusion of various concentrations and sources of sea tangle did not significantly affect the growth, feed efficiency, body composition or plasma chemistry of juvenile black porgy.

  • Waxy barley flour was fermented by two kinds of starter cultures; L. plantarum and L. brevis, alone or in combination and the effect was evaluated on waxy barley and wheat composite bread quality. In all three barley sourdoughs, fermentation decreased the pH, total sugar and reducing sugar, and increased lactic acid bacteria cell numbers. However yeasts (S. cerevisiae) were reduced. There was significant difference in physicochemical characteristics between the reference(composite barley dough containing improvement agent) and the barley sourdoughs (p <0.05). Barley sourdough fermented by L. plantarum showed more desirable farinogram properties of peak time, stability and elasticity than that of the reference. The rheofermentometer data for L. brevis produced the most $CO_2$ release curve, whereas L. plantarum held maximum $CO_2$ retention differed significantly from that of the breads made with barley sourdoughs fermented with the respectives starter cultures (p < 0.05). Barley sourdough bread fermented with L. plantarum resulted in better bread quality than the reference bread. The positive effect of fermentation with L. plantarum on bread quality was evident when comparing the well developed protein-starch matrix structure of the bread baked with barley sourdough with the reference bread.

  • This study was performed to determine the effect of temperature condition on growth of juvenile abalone Haliotis discus hannai with the different feeds. Two types of feed (dry sea tangle and experimental diet) at water temperatures of 20 and $23^{\circ}C$, and 23 and $26^{\circ}C$ were applied to experimental abalone twice. Forty-five juvenile abalone averaging 10.1 g in the first feeding trial and 11.5 g in the second feeding trial were randomly stocked into 6 of 50 L plastic rectangular containers each. Fishmeal, soybean meal and shrimp head meal was used as the primary protein source in the experimental diet. And dextrin and wheat flour, and soybean oil were used as the primary carbohydrate and lipid sources in the experimental diet, respectively. The dry sea tangle and experimental diet were fed to abalone once a day at the ratio of 1.5-2.0% total biomass of abalone with a little leftover in each experimental condition. Weight gain of abalone was significantly affected by feed type, but not by water temperature in the first feeding trial. Regardless of water temperature, weight gain of abalone fed the experimental diet was significantly higher than that of abalone fed the dry sea tangle. However, weight gain of abalone was significantly affected by water temperature, but not by feed type in the second feeding trial. Weight gain was highest in abalone fed the experimental diet at $23^{\circ}C$, followed by abalone fed the dry sea tangle at $23^{\circ}C$, abalone fed the experimental diet and dry sea tangle at $26^{\circ}C$, which was lowest. Moisture and crude protein content of the edible portion of abalone was significantly affected by feed type, but not by water temperature in the second feeding trial. However, ash content of the edible portion of abalone was significantly affected by water temperature, but not by feed type. In considering these results, it can be concluded that the well formulated feed was superior to the dry sea tangle for growth of juvenile abalone, and water temperature conditions of 20 and $23^{\circ}C$ seemed to be better than $26^{\circ}C$ to improve weight gain of abalone.

  • This study evaluated the quality characteristics of muffins prepared with different amounts (0%, 4%, 8%, or 12%) of apricot powder. The moisture content was higher in groups containing 8% and 12% apricot powder. The specific volume of muffins decreased as the amount of apricot powder increased. The lightness value was lower in groups containing apricot powder, with redness and yellowness values increasing with increasing amounts of apricot powder. Rheology tests showed no significant differences in hardness, springiness, and cohesiveness between control muffins and muffins with apricot added. Scanning electron microscopy showed that the number and size of air cells decreased with increasing levels of apricot powder. The substitution of wheat flour with apricot powder yielded muffins with a higher DPPH (1,1-diphenyl-2-picrylhydrazyl) radical-scavenging activity and total polyphenol content. Consumer acceptance tests revealed no significant differences in appearance, smell, and texture between muffin samples, but the taste and overall acceptability scores were lowest for muffins with 12% apricot added. Therefore, up to 8% apricot powder can be incorporated into muffins to meet the sensory quality and functional needs of the consumer.
