  • In order to obtain the most favourable classification system for fishing gears, the problems in the existing systems were investigated and a new system in which the fishing method was adopted as the criterion of classification and the kinds of fishing gears were obtained by exchanging the word method into gear in the fishing methods classified newly for eliminating the problems was established.

  • This study was carried out in order to investigate the effects of lotus leaf extracts on the quality characteristics of beef jerky, such as chemical composition, free amino acid, Hunter's color, physical properties, water activity, pH, TBARS value, VBN content, total bacterial count and sensory score. According to the results, there were no significant differences in moisture, protein, fat, ash, L-value, b-value, hardness, springiness, cohesiveness, gumminess, chewiness, water activity, pH, flavor, taste, texture, juiciness and overall acceptability. Total free amino acid content was highest in T0 and, lowest in T3 (p<0.05). The a-value was highest in T3 (p<0.05). The TBARS value and total bacterial count of T2 and T3 were significantly lower than those of T0 and T1 (p<0.05). The VBN content was lowest in T3 (p<0.05) and the sensory color was highest in T3 (p<0.05).

  • The physicochemical properties, antioxidant activity, color value, sensory evaluation, and sinigrin content of chicken breast jerky supplemented with Dolsan leaf mustard powder (DLMP) were evaluated over a period of 120 days. The control groups contained no DLMP, and the product groups contained 0.04 g (S-1, S-3) and 0.3 g (S-2, S-4) of DLMP. These samples were stored at 25℃ and 60℃ and then compared. The pH changes decreased at 25℃ and 60℃ over the storage period, with S-1 maintaining the highest pH value over the course of the experiment. The acid and peroxide values increased at room temperature and 60℃ but were better controlled in the DLMP-containing groups. Overall, the antioxidant activity of these products decreased during storage; the most marked reduction was observed in the control group, and the greatest activity was retained in S-2 and S-4. Hardness and gumminess were higher in the S-2 and S-4 groups and thus correlated with increased DLMP concentration. Sinigrin content also increased with increasing DLMP concentration. Product color remained similar at days 0 and 120 but underwent daily fluctuations over the course of the 120-day storage period. Sensory evaluation scores for color, flavor, taste, texture, and overall acceptability were highest for the S-2 and S-4 groups stored at 25℃. This suggests that higher concentrations of DLMP were more effective at retaining good quality characteristics for fried chicken breast jerky. This was facilitated by its suppression, which decreased changes in textural and color properties while increasing the antioxidant activity of these products.

  • Seasoned and dried squid slice (SDSS) was prepared with surimi and squid, and investigated on the food component characteristics. The moisture and water activity of the SDSS slightly increased with increasing addition ratio of squid. According to the increase of addition ratio of squid, sensory scores of SDSS decreased in the color, whereas increased in the taste. There was, however, no difference in sensory flavor and texture between SDSS prepared with various ratios of squid. The results of physical properties and sensory evaluation suggested that the desirable addition ratio of squid was more than 70% based on the mix for preparing SDSS. There was no difference in total amino acid content between seasoned and dried slices with, which was prepared by a ratio of squid(70): surimi (30), and without squid. The major amino acids of SDSS were glutamic acid, leucine, lysine and threonine. The calcium and phosphorus contents of SDSS were 85.9 mg/100g and 458.3 mg/100g, respectively. The total free amino acid content and taste value of SDSS were 3,1991mg/100g and 402.00, respectively. The taste values of SDSS suggested that the major taste-active compounds were glutamic acid and aspartic acid.

  • Chicken breast jerky (CJ) was prepared by drying chicken breast at $50^{\circ}C$ for 9 hrs after marinating it in a various sweetening sauce including white sugar (WS), brown sugar (BS), rice syrup (RS), fructooligosaccharide (FO), pineapple concentrate (PC), Rubus coreanus extract (RCE), or honey (H), and its physicochemical and sensory properties were investigated. The CJ was found to contain 22.5-25.0% moisture, 41.0-46.6% protein, and 0.4-1.0% fat, which indicates that it could serve as a high-protein and low-fat snack. The type of sweeteners significantly affected the yield, pH, total viable cell count, and water activity of the CJ, showing ranges of 40.9-50.1%, 5.2-5.9, $2.5-6.2{\times}10^4CFU/g$, and 0.74-0.81, respectively. Both the water activity and pH were the lowest in CJ-RCE where of the highest in CJ-WS. The cohesiveness, springiness, and chewiness of the CJ significantly differed depending on the type of sweeteners (p<0.05). CJ-RCE showed the best taste and overall acceptability in a sensory test. After storage at $50^{\circ}C$ for 2 weeks, thiobarbituric acid reactive substance (TBARS) content (58.3 malondialdehyde (MDA) mg/kg) of CJ-RCE was much lower than those of control beef (75.6 MDA mg/kg) and pork jerky (98.0 MDA mg/kg), showing the good oxidative stability of CJ-RCE. Overall, marination in RCE sauce was suitable for the preparation of CJ with good quality in terms of its water activity, fat and protein contents, sensory property and oxidative stability.

  • To determine the proper processing and storage conditions, physico-chemical, microbial and sensory properties of venison jerky under different dry times were measured during storage at $30^{\circ}C$ for 28 days. Samples were dried for 3 hr (T1), 4 hr (T2) and 5 hr (T3) at $75^{\circ}C$ in the smoke chamber, respectively. The pH of T1 was slightly lower than those of T2 and T3 as storage time increased. As dry and storage time increased, TBARS of T2 and T3 were significantly higher (p<0.05) than that of T1. In meat color, $L^*$ values of T3 showed slightly higher than those of T1 and T2, while at values were not clearly tendency by the passage of storage time. $b^*$ values of T2 and T3 were higher than that of T1. The water activity were significantly lower (p<0.05) in ,the order of T3$log_{10}$ CFU/g until 28 days and its number were accepted by sensory evaluation. In conclusions, T2 and T3 showed slightly high overall acceptability and lipid oxidative stability compared to T1 conditions. These results indicated that longer dry time ($4{\sim}5 hr$) of venison jerky would be better characteristics as compared to shorter dry time (3 hr) with increased storage time at $30^{\circ}C$.

  • In this paper, an optimization program for the design of wiper mechanisms is developed to minimize jerky motion while satisfying design constraints on kinematic and torque performances, mobility condition, and packaging. The lengths/orientations of the links and the position of a driving motor are selected as the design variables. In our optimum design program for wiper mechanisms, an optimization module interacts with an analysis module which calculates kinematic and force/torque properties, until convergence. The optimization results of a particular wiper mechanism are presented to illustrate the effectiveness of the program developed.
