  • In order to stabilize the price of fresh ginseng by extension of seasonal variation and marketing structure, and to reduce the cost of production by works of intensive and short term, studies were carried out. As fresh ginseng of 4 years old by the MA and CA was stored for 12 week at 4$^{\circ}C$, samples were collected after every 1, 2, 3, 4, 6, 8, 12 weeks for processing red ginseng. Color and Sensual characteristics on ginseng steamed red for the quality evaluation are summarized as follows. For the time course of storage with red ginseng, which was processed from fresh one after various treatments, L and b values were decreased, however a value was increased. In particular, absorbance was step-wisely increased. Turbidity was somewhat increased, and non-treatment of preservative were shown 2 times higher of absorbance. Extraction ratio of ethanol-soluble extractives slightly increased by the preservation methods, and as storage period was passed. CA storage and preservative treat merit versus MA and non-preservative treatment gave much stability in ginseng quality. In the sensual characters, sour taste and sweet taste were increased, but fresh taste and rice scorched taste were decreased. Bitter taste was not much changed until end of storage. CA was shown smaller differences than MA in the pH change. Addition of preservative extended the storage time.

  • We investigated the quality and sensory characteristics of model tomato sauces which was made from fresh Vitaking tomatoes and American canned tomatoes in the mixture ratios of 0:100% ($S_1$), 25:75% ($S_2$), 50:50% ($S_3$), 75:25% ($S_4$) and 100:0% ($S_5$). Soluble solids, reducing sugars, vitamin C and organic acids increased as the contents of fresh tomatoes increased. pH and contents of $\beta$-carotene and lycopene decreased as the contents of fresh tomatoes increased. Lightness(L value) and yellowness (b value) increased as the contents of fresh tomatoes increased whereas redness (a value) didn't show any significant differences among samples. In the preference test, $S_3$ was the most preferred in red color, taste and overall preference. In the descriptive test, $S_1$ ranked the highest in redness, viscosity, palatability and flavor except for sweet and sour taste. $S_5$ was the lowest in redness, viscosity and palatability, being the highest in sour taste. From this result, we found that the mixture ratio of half fresh tomatoes and canned tomatoes was the best condition to make tomato sauce with preferred red color.

  • Clam, Tapes japonica, has been widely used and occupies an important position in the markets. More than thirty kinds of fermented fish and shellfish are presently available in the markets in korea. This study was attempted to establish the basic data for evaluating the taste compounds of the clam. The free amino acids as taste compounds during the fermentation of the clam, Tapes japonica, were analyzed by an amino acid autoanalyzer. Alanine (17.0%), glycine (15.5%), taurine (13.9%) were high in amount in the fresh clam and then glutamic acid, arginine, tyrosine, asparagine, lysine, threonine, serine and leucine were the next in order. Such amino acids as methionine, phenylalanine, histidine and cystine were low in amounts. The total free amino acid nitrogen in the fresh clam was 45.5% of its extract nitrogen. During the fermentation of the clam, the kinds of the free amino acids were the same with the fresh samples although the amounts were changed. It is believed that glutamic acid, aspartic acid, glycine, alanine, lysine, and leucine may play an important role as the taste compounds in the fermented clam.

  • This study evaluated how fresh pear cognition variables influences the purchase of primary and secondary products to promote pear consumption. The survey was performed online using 200 consumers who have consumed pears. Consumers' cognition was classified into two groups, one that was more favorable toward fresh pears and one that was less favorable. The cognition toward pear significantly affected the attitude (p<0.001) and purchase intention (p<0.001) toward fresh pear. When consumers bought fresh pear, sweetness was most important among the selection attributes to both groups, and the most common reason why consumers liked the pear analyzed by check all that apply (CATA) was also sweet taste. However, the negative group did not prefer fresh pear because of taste and texture, so those qualities should be well-controlled. In addition, cognition toward primary products influenced liking and purchase intention of processed pear products, especially beverages (p<0.001), bakeries and sweets (p<0.05). Therefore, these types of secondary products should be developed based on consumers' demands.

  • The purpose of this study was to investigate the effects of basil on the quality characteristics of tomato sauce, which is used widely in Western cuisine. The highest pH of 4.29 was observed in the tomato sauce with 4% fresh basil added, while the tomato sauce with 0% fresh basil exhibited the lowest pH of 4.20. The pH of the tomato sauce gradually increased with the addition of fresh basil. The analysis of color differences in the tomato sauce indicated that redness(avalue) decreased with the addition of basil;, whereas consistency and spreadability increased with the increasing amounts of the fresh basil. The sensory evaluation was performed with scoring tests for color, flavor, taste, after taste, viscosity, and overall acceptability by 15 professional panelsists. The tomato sauce with 2% basil showed the best score in the sensory evaluation, except for vicosity. From the above results, the data suggest that an addition of 2% fresh basil to tomato sauce is recommended for commercial use.

  • The study was carried out to compare the factors of overall preference In the sensory test to the analyzation of some compositions in the 7 kinds of old grasses : An Evening Primerose, a Spiderworts, the flower of a Convolvulus, So Ru Jang Yl, Shoe Bl Rum.O Yi Pul, Jip Sean Na Mul. Results were summaries as follows. 1. The Tannin contents of fresh sample and cooked samples were determined as 0.27~2.4g%, 0.25~1.439% respectively. The largest amount of fresh samples was contained In a Shoe Bi Rum. The smallest amount of them was in an Evening Primerose. The highest level of cooked samples was found in a Shoe Bi Rm, and the lowest was in the O Yi Pul. These results were similar to sensory test. 2. The free amino acid contents of 2 kinds of samples were determined as 25.15~179.5mg%, 1.86~13. 6mg% respectively. The largest amount of sweet taste of them was 0 Yi Pul and So Ru Jaeng Yl respectively. But So Ru Jaeng Yi is not appeared sweety becase this have much tannin. The smallest amount of sweet taste was a Spiderwort. The highest level of bitter taste was So Ru Jaeng Yl the and lowest was Jip Sean Na Mul. Among of them Jlp Sean Na Mul is similar to organoleptic test but So Ru Jaeng Yi is not strong bitter taste in sensory evaluation. The highest level of sour taste of cooked samples was So Ru Jaeng Yi and the lowest of them was Shoe Bi Rum. The reducing sugar contents of fresh sample and cooked samples were determined as 1.80~ 4.9g%, 1.84 ~3.579% respectively. The largest of fresh samples were So Ru Jaeng Yl and the lowest was Shoe Bi Rum. The highest of cooked samples were an Evening Primerose and the lowest was a Convolvulus. Among of these results an Evening Primerose was not similar to sensory test because it has much other components. The level of chlorophyll of fresh samples and cooked samples were determined as 11.7~39mg%, 11.3~40.3mg% respectively. The highest of fresh samples was Shoe Bl Rum and the lowest was J ip Sean Na Mul. The largest of cooked samples was So Ru Jaeng Yi and the lowest was a Jlp Seu Na Mul.

  • This study was attempted to evaluate the taste of broiled-dried sea mussel which is a traditional dried Sea food in Korea. The contents of such compounds as free amino acids, nucleotides and their related compounds, TMAO, betaine, and nonvolatile organic acids were analysed. From the results of analysis of nucleotides, the contents of AMP and ADP in broiled-dried Mytilus coruscus and Mytilus edulis appeared higher than other nucleotides and tended to increase slightly after cooking, drying, and storage which might be due to both their stability and the addition of degradation of nucleic acids during cooking. In the free amino acid composition of fresh samples abundant amino were taurine, glycine, serine, glutamic acid, alanine, arginine, threonine, tyrosine, lysine and valine in order. Such amino acids as histidine, leucine, methionine and isoleucine were poor and both proline and phenylalanine were merely trace. The free amino acid composition in the extract of Mytilus corucus and Mytilus edulis after broil-drying was not changed. These amino acids, taurine, glycine, feline, glutamic acid, alanine and arginine were abundant in dried samples as well as in the fresh. The total free amino acid was greatly reduced after cooking and drying ranging from $76.3\%$ to $79.7\%$ loss to that of tile fresh. The content of betaine shelved the same tendency as in total free amino acid while TMA slightly increased relating to TMAO decrease during broil-frying. Such nonvolatile organic acids as succinic, lactic, malic and fumaric acid were abundant in both fresh and broiled-dried samples whereas oxalic and pyruvic acid were poor. It is found that the taste compounds of broiled-dried Mytilus coruscus and Mytilus edulis were composed of amino acids as glycine, serine, alanine, glutamic acid, arginine, and betaine, TMAO, ADP, AMP, and organic acids such as succinic acid, lactic acid, malic acid and fumaric acid. No significant differences in the taste compounds between male and female as well as between Mytilus coruscus and Mytilus edulis was not observed.
