  • This study evaluated the nutritional composition and quality traits of rabbit meat as compared to chicken meat. Samples of loin (M. longissimus dorsi) and breast meats were collected from rabbit and chicken carcasses, respectively. The meats were then analyzed for the proximate composition, collagen and energy contents, fatty acid composition, myoglobin and heme iron contents, pH value, water-holding capacity (WHC), cooking loss, meat color, Warner-Bratzler shear force (WBSF) value, and texture profile. Compared to chicken breast meat, lower (p<0.05) protein content and higher (p<0.05) ash and collagen contents were obtained in rabbit loin meat. Rabbit meat remarkably had higher (p<0.05) total polyunsaturated fatty acids (PUFA) and linolenic acid contents and lower (p<0.05) n-6/n-3 PUFA ratio as compared to chicken meat. The pH value and WHC were lower (p<0.05) in rabbit meat than in chicken meat (p<0.05). Rabbit meat exhibited lower (p<0.05) L* value and higher (p<0.05) a* and b* values compared to chicken meat (p<0.05). The WBSF value, hardness, and gumminess were higher (p<0.05) in rabbit meat than in chicken meat (p<0.05). These findings suggest that rabbit meat has higher essential n-3 PUFA, darker color, and firmer texture as compared to chicken meat.

  • Purpose: This study examined the food composition of four raw and boiled domestic potato cultivars: Superior, Dejima, Bora Valley and Rose. Methods: Proximate composition (moisture, protein, ash, dietary fiber and fat), minerals (calcium, phosphorus, iron, potassium, sodium and magnesium) and vitamins (thiamine, riboflavin and niacin) were analyzed in the study. Results: In this study, it was observed that the moisture contents of raw and boiled Bora Valley potato were 83.74 g/100 g and 81.57 g/100 g, respectively, which was highest among the studied cultivars. The protein content of the raw and boiled Rose potato (12.23 g/100 g and 11.02 g/100 g) was higher than that of the other cultivars. Protein contents of boiled Bora Valley and Rose potatoes were significantly lower than those of their respective raw samples. The potassium, phosphorus and sodium contents of Bora Valley potato were 2,397.69 mg/100 g, 389.13 mg/100 g and 14.12 mg/100 g, respectively. In case of raw potato, the calcium, iron and magnesium contents of Dejima potato were 51.52 mg/100 g, 3.21 mg/100 g and 137.62 mg/100 g, respectively, which were the highest values among the tested potato cultivars. Total dietary fiber content of Dejima potato was 14.78 g/100 g, which was the highest level. The dietary fiber contents of four cultivars of potatoes were lower after boiling. Thiamine content was highest in the Bora Valley potato (0.43 mg/100 g). Riboflavin contents of the Rose potato was 0.35 mg/100 g, which was higher than that of the others. Conclusion: Overall, four cultivars of raw and boiled potatoes had enhanced food composition. Therefore, these potato cultivars are expected to be highly valuable food items for the development and application of functional foods.

  • To improve the bending strength of sawdustboard, verious resin contents of 10, 13, 16, and 19% were applied to the thin shell (face layer) composed with wire net or not. The shell effect of sawdust and wire net composition formed with core sawdustboard were evaluated. Forcusing on the effects of wire net composition and noncomposition including a comparison with chipboard and veneer complyboard, bending properties (Modulus of rupture (MOR), Modulus of elasticity (MOE), Stress at proportional limit ($S_{pl}$). Work to maximum load ($W_{ml}$))were analyzed and discussed. 1. In modulus of rutpute, veneer comply was the highest (621.5 kg/$cm^2$), and next decreasing order was wire net composition (159.1 kg/$cm^2$), chipboard (81.75 kg/$cm^2$), and wire net noncomposition (76.21 kg/$cm^2$) as in modulus of elasticity, work to maximum load, except for stress at proportional limit. 2. The highly significant effects were shown in both wire net composition and noncomposition, at the same time wire net composition exceeded two times of noncomposition throughout resin contents in bending properties. Chipboard was similar to the mean or 16% resin content in noncomposirion. 3. Every board in wire net composition above 10% resin content was beyond 100 kg/$cm^2$ in MOR, minimum allowable strength for structural use according to KS F 3104. In conclusion, the feasibility for improving the bending strength of weak sawdustboard by wire net composed shell was offered.

  • After casting button-type small ingots of ternary Fe-Mn-S alloys which had three different Mn/S ratios (1, 5 and 70) in a vacuum arc furnace, the effect of the ratio on the sulfide formation was investigated. In case of the Mn/S ratio of 1, if alloy composition was located in an iron-rich corner on a Fe-Mn-S ternary phase diagram, only duplex MnS-FeS sulfide films were observed in the grain boundary. If the alloy composition was located in the miscibility gap area of the phase diagram, primary globular dendritic sulfides and dendritic sulfide slags were generated within the grain and tubular monotectic sulfides were also detected in the grain boundary. When the Mn/S ratio was 5, if the alloy composition was in the iron-rich corner, only bead-like sulfides were generated. On the other hand, if the composition was in the miscibility gap area, globular dendritic sulfides and dendritic sulfide slags were generated in the form of primary sulfide inclusions and rod-like eutectic sulfides were observed in the grain boundary. Especially, if the contents of Mn and S increased more in the miscibility gap area of the phase diagram, primary globular sulfides containing iron intrusions were observed. In case of Mn/S ratio of 70, if the contents of Mn and S was decreased in the Fe corner of the phase diagram, only bead-like sulfides were observed in the grain boundary. Despite the composition was outside the miscibility gap area of the phase diagram, if the contents of Mn and S increased, clusters of fine sulfide particles as well as fine spherical primary monophase sulfides were observed in the grain boundary.

  • This study investigated the effects of astaxanthin, which is used to improve the muscle color of fish, on the nutritional composition of rainbow trout (Oncorhynchus mykiss). The trout were fed extruded pellets containing astaxanthin (pigmented rainbow trout) or without astaxanthin (non-pigmented rainbow trout). No significant differences in the contents of crude protein and crude ash between the two muscles of the two groups were observed. However, the crude fat composition of the muscle of pigmented rainbow trout was about two times higher than that of control muscle. In the muscle of pigmented rainbow trout, the contents of docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3), which are functional polyunsaturated fatty acids, were 1.6 fold higher than in non-pigmented muscle. In addition, the contents of minerals such as Zn and Fe, vitamins (B group, C, and E), free amino acids, carotenoids and astaxanthin were increased in the muscle of rainbow trout fed pellets supplemented with astaxanthin. Specifically, the content of the bioactive compound astaxanthin, was increased six times in the pigmented muscle, as compared to the control muscle. The results suggest that a diet supplemented with astaxanthin improves the nutritional composition of rainbow trout muscle as well as improving the muscle color.

  • The objective of this study was to develop the classification method of various organic wastes. Specifically, the effects of proximate composition on the biogas production and degradation rates of agricultural by-production was investigated and a new standards for mixture of various organic wastes based on proximate composition combination was developed. Agricultural by-products (ABPs) with medium total carbohydrate, medium crude protein and low fat contents demonstrated the single step digestion process. ABPs with low total carbohydrate, high crude protein and high fat contents demonstrated the two step digestion process of Diauxic growth. The single ABP (Class No. 15) and the mixed ABPs (Class No. 12+18, 6+12+22, 9+12+18) after 10days showed the similar biogas yield pattern. We can use the classification method for the more ABPs and organic wastes from factory and municipal waste treatment plant for the high efficient biogas production.
