  • Two of the Hard White Winter (HWW) wheats had higher farina yield than mixed Hard Red Winter (HRW) wheat. Optimum steaming time for HRW farina spaghetti was 3min under 86-98$^{\circ}C$. Optimum cooking time decreased after steam treatment. Steam treated spaghetti showed much higher strength of dried spaghetti, lower cooking loss, and cooked weight, less stickiness, and total organic matters (TOM) value than in treated spaghetti after cooking. The rooking qualities except stickiness were significantly different between treated and untreated steam. The quality of hard wheat farina spaghetti was more affected than that of durum spaghetti after steam treatment. HWW farina spaghetti im-roved all the qualities of steam treated and untreated spaghetti than those of HRW farina spaghetti except stickiness. From the observations of scanning electron microscope (SEM), maybe two general principles of steaming can be explained by : i) forming hydrophobic protein film on surface of pasta, ii) higher retrogradation of starch, which cause less swelling of starch.

  • The hardness of hard red winter (HRW) wheat had an effect on the yield of farina , as it positively correlated with the coarse fraction (over 34W) and negatively correlated with the flour fraction from farina milling. But it did not show any significances on flour milling from the micromilling process. The flour yields was better correlated with the break flour fraction (r=0.730 than with reduction flour (r=0.27). The farina yield was controlled by a fraction over 34W (coarse granule0. Protein was the most important single factor for the quality of cooked farina spaghetti, but not for flour milling or farina milling. On the other hand, hardness was important in the production of farina milling , whereas it did not govern spaghetti cooking quality, Environmental factors affected the quality of cooked spaghetti as much as varieties of HRW wheats. The quality of cooked farina spaghetti generally correlated with the protein in the location composites of wheats. Higher protein content wheats showed better spaghetti cooking quality.

  • The in vitro digestive properties of 6 domestic noodle products (spaghetti, somyeon, ramyeon, dangmyeon, naengmyeon, and jjolmyeon) were compared after cooking under the manufacture's recommended cooking conditions. The kinetic constant (k), representing the rate of hydrolysis at the initial digestion stage, was highest in the somyeon noodles (0.1151), followed by naengmyeon (0.0954), and was lowest in the spaghetti (0.0421). However, the concentration of starch ($C_{\infty}$) hydrolyzed over 2 hr was not different between the spaghetti (96.22) and the somyeon (96.40), indicating that different digestion behaviors occurred in each type of noodle, even though the amounts of digested starch were similar. The ramyeon, dangmyeon, and naengmyeon noodles showed relatively lower $C_{\infty}$ values than the spaghetti and the somyeon noodles. The spaghetti had the highest amount of slowly digestible starch (SDS, 43%) and the lowest glycemic index (GI, 87.8), whereas the somyeon had the lowest SDS value (9.6%) and the highest or (93.0). The digestibility differences among the noodles were attributed to differences in their flour compositions and manufacturing processes.

  • This paper examines the Spaghetti bowl effect that different tariffs and rules of origin in multiple FTAs have resulted in increasing the significantly additional burden for business when it comes to apply for the use of FTA preference. The wide spread of FTAs in the several years, from 2003 to 2010, has been the most important trade policy development in economically important Korea. Korea presently has 5 FTAs in effect, and made 3 additional agreements which will be expected to take effect in next year. With the study result and expecting a growing number of FTAs in Korea in a next decade, the international trading firms will face rise of transaction costs for enterprises, particularly small- and medium-sized enterprises(SMEs) to cope with multiple tariffs and rule of origins in FTAs. To help mitigate negative effects and facilitate a more SEMs to use the FTA preference, providing new computer programs system, increasing the awareness of FTA provisions, improving business participation in FTA consultations, and SME support in light of education, and financial support are needed.

  • Cooked spaghetti soaked in 10%, 20%, and 40% aqueous glycerine solutions for ten minutes absorbed sufficient glycerine to plasticize that spaghetti during and after subsequent drying. The plasticizing action of the glycerine prevented fissuring(checking) and surface corrugation of the spaghetti at elevated drying temperature and large wet-bulb dry-bulb temperature difference. The drying temperature and the wet-bulb dry-bulb differences up to which such protection was provided as the glycerine soak concentration increased. Despite the reduction in drying rate, the drying time required to produce spaghetti with a water activity of 0.65 (the level normally required for stability) decreased as glycerine content increased. At high frying temperatures glycerine addition increased the extent of browning and shortened the period required to induce detectale browning, but in all instances browning started well after the product $a_w$ reached the 0.65 value required for the completion of drying. Because glycerine addition reduced drying times at any given set of drying conditions and permitted the use of higher drying temperatures, relatively low levels of glycerine addition (e.g. 0.15 kg glycerine/kg dry spagetti) can shorten spagnetti drying times by roughly 80% and perhaps by as much as 93%.

  • This study was carried out to prepare spaghetti sauce with adductor muscle of pearl oyster (SSAM) and to compare with commercial spaghetti sauce (CSS). From the results of organic acid, pH, hunter color value and sensory evaluation, the optimal addition ratio of adductor muscle of pearl oyster was 11% based for preparing SSAM and reasonable $F_0$ value was about 4 min for keeping storage of SSAM. The proximate composition of SSAM was 69.8% for moisture, 3.7% for protein, 4.2% for crude lipid and 3.4% for crude ash. SSAM was superior in sensory flavor and texture to CSS. There was, however, no significant difference (p<0.05) in sensory color between CSS and SSAM. The total amino acid content (3,033.4 mg/100 g) of SSAM was higher than that (2,305.7 mg/100 g) of CSS and the major amino acids were aspartic acid, glutamic acid, leucine and lysine. Calcium and phosphorus contents in SSAM were 48.5 mg/100 g and 27.1 mg/100 g, respectively. Calcium level based on phosphorous was 1.78, which was a good ratio for absorbing calcium. The free amino acid content and taste value of SSAM were 989.4 mg/100 g and 141.04 mg/100 g, respectively These results suggested that the major taste active compounds among free amino acid were glutamic acid and aspartic acid.

  • The study was carried out to prepare spaghetti sauce with oyster (SSO) and the food components characteristics of the SSO were also compared to those of commercial spaghetti sauces (CSS). The optimal addition ratio of oyster for preparing SSO was 11% based on 100 g of SSO according to the results of organic acid content, Hunter color value, viscosity, and sensory evaluation. The reasonable $F_0$ value for the keeping storage of SSO was about 4 min. The proximate composition of SSO prepared under the optimal processing condition was 71.2% moisture, 2.8% protein, 6.9% crude lipid, and 3.2% crude ash. The results of sensory evaluation suggested that the quality of SSO was superior to that of CSS. However, there was no significant difference (p<0.05) in sensory evaluation on color between CSS and SSO. The total amino acid content (2,532.2 mg/100 g) of SSO was higher than that of CCS (2,305.7 mg/100 g). The contents of calcium and phosphorus of SSO were 25.7 mg/100 g and 48.7 mg/100 g, respectively. The calcium content/phosphorus content showed a suitable ratio for absorbing calcium. The total free amino content and the taste value were 1,040.2 mg/100 g and 151.26, respectively. The major taste-active amino acids were glutamic acid and aspartic acid.

  • Sunspot substructure is an important subject to explain their stability and energy transport. Previous studies suggested two substructure models, monolithic and spaghetti model, but no clear evidence has been found supporting a particular model. To obtain the clue of the sunspot substructure the IRIS Mg II 2796Å slit-jaw images (SJI) were examined. The Mg II images formed in the chromosphere show bright patches inside umbrae which are regarded as an observational signature of upward propagating slow magnetohydrodynamic (MHD) waves. The slow MHD waves are expected to be generated by convective motion below the photosphere. By tracking the motion of the bright patches it is possible to estimate the locations of oscillation centers that correspond to the occurrence position of the convections. I investigated the spatial distribution of the oscillation center in a merging sunspot and found it is randomly distributed. It implies that the occurrence rate of the convective motion inside the sunspot is not much different from that of between the two sunspots, and supports the spaghetti model as the sunspot substructure.

  • This study was conducted to develop a novel tomato sauce using natural seasoning. The data was analyzed using SPSS for Windows (version 14.0). Two factors of the tomato sauce were varied was tomato paste and sugar. Nine tomato sauces were produced with various compounding ratios of tomato paste and sugar. The color, viscosity and sensory evaluations of the nine tomato sauces were determined. Items examined in the sensory evaluation were color, sweetness, viscosity and overall quality. Sweetness($4.44{\pm}1.36$), viscosity($5.16{\pm}1.28$) and overall quality($4.68{\pm}1.11$) of the tomato paste 340g and sugar 100 g sample got highest scores. Therefore, this composition was used as tomato spaghetti sauce. Tomato spaghetti sauce using a natural tomato sauce and artificial tomato sauce was prepared and subjected to a sensory evaluation. Items included in the sensory evaluation were taste, flavor, harmony, overall quality. In this analysis, all sensory item scores of the tomato spaghetti sauce using natural seasoning were significantly higher than when artificial seasoning was used. Therefore, the potential of commercialization of tomato sauces using natural seasoning was confirmed.
