  • The purpose of this study was to develop a seasoned Hwangseoke-jeot(a kind of salted and fermented fish) with chitosan having less fishy smell and salty taste. In order to decrease the fishy smell and increase the palatable taste effectively, four types of seasoning were developed, in which minced ginger, garlic and onion were included. In order to improve the color and flavor of seasoned Hwangseoke-jeot, high-quality powdered hot red pepper was also added in all the seasonings. Seasoned Hwangseoke-jeot type 1 had the oil and roasted powder of sesame, which are known to decrease fishy smell and palatable taste, and was the basis of other seasoned Hwangseoke-jeot. Type 2 had the oil and roasted powder of perilla, which also were known to decrease fishy smell and to increase palatable taste effectively. Type 3 had roasted soybean powder and laver to increase savory and palatable taste. It was developed especially for old and young people who like savory taste. Type 4, containing citron syrup, was for the young and children. All the developed seasoned Hwangseoke-jeot samples had better red color and other sensory properies than the control (S-company's seasoned Hwangseoke-jeot), as tested by colorimetry and sensory evaluation. More than 1% (w/v) of chitosan gave an astringent taste to seasoning, so it is recommended not to exceed 1% (w/v) in the seasoning. The developed functional seasonings of jeot would be applicable to other kinds of jeot.

  • Taste is associated with hedonic evaluation as well as recognition of quality and intensity. Taste information is sent to the cortical gustatory area in a chemotopical manner to be processed for discrimination of taste quality. It is also conveyed to the reward system and feeding center via the prefrontal cortices. The amygdala, which receives taste inputs, also influences reward and feeding. In terms of neuroactive substances, palatability is closely related to benzodiazepine derivatives and $\beta$-endorphin, both of which facilitate consumption of food and fluid. The reward system contains the ventral tegmental area, nucleus accumbens and ventral pallidum and finally sends information to the lateral hypothalamic area, the feeding center. The dopaminergic system originating from the ventral tegmental area mediates the motivation to consume palatable food. The actual ingestive behavior is promoted by the orexigenic neuropeptides from the hypothalamus. Even palatable food can become aversive and avoided as a consequence of postingestional unpleasant experience such as malaise. The brain mechanism of these aspects of taste is elucidated.

  • This studies was conducted to elucidate the taste components of shellfishes, producted in Korea. Four kinds of shellfishes including sea mussel, short-necked clam, corb shell and ark ahell were selected according to the higher sales order and cheaper retail price at 50 fish markets in Seoul in August 1982. The results are : Palatable taste of shellfishes should be caused by nucleotide related products, organic acids and free amino acids. Thus taste components found in four shellfishes were succinic, fumaric, and lactic acids as organic acids, glycine, alanine and glutamic acid as free amino acids.

  • Effect of temperature on Kakdugi during fermentation was investigated by measuring sensory, physicochemical and microbiological, properties up to 57 days. The diced(2.5$\times$2.5$\times$2.5cm) Chinese radishes(Ra-phanus sativus L.) with other ingredients were fermented under the different temperatures. Kakdugi were stored at 4$^{\circ}C$ after keeping at 2$0^{\circ}C$ for 12 hours(treatment E) from initial fermentation to the end at each temperature on preparation. The pH was decreased to the range of 4.14~4.29 in the initial of pH 5.8, and total acidity was increased 2~4 times more than that of in the initial period (0.24%). And the changes of treatment A, B, and C were nearly constant up to 57 days in the range of 0.80~0.88% (pH 4.1). The changes of vitamin C showed sigmoidal curve, increasing significantly in the palatable period after decreasing gradually in the initial period. The content of vitamin C in treatment E was rapidly decreased, but that of treatment C was kept high content up to 57days. the number of lactic acid bacteria was remarkably increased in palatable period and was gradually decreased thereafter. The scores of aroma, taste, overall acceptability in sensory evaluation during the fermentation was high in order of treatment E, C, D, B and A. The scores of sensory evaluation treatment D and E during fermentation was rapidly decreased, however, treatment A, B and C were maintained. Changes of lactic acid bacteria, and sensory properties, among treatment A, B and C which kept a good quality up to 57 days, had high scores of sensory evaluation, abundant vitamin C in the palatable period. The result showed that Kakdugi fermented at 4$^{\circ}C$ after keeping at 2$0^{\circ}C$ for 36 hours had better taste and quality than those of other treatments.

  • Effect of Fermentation temperature on the changes of chemical components in Kakudgi during fermentation was investigated by measuring free sugar, organic acid and volatile compounds up to 57 days at several temperatures. The mannitol was increased in palatable period in contrast with those of other free sugars. The higher the initial fermentation temperature was and the longer the initial fermentation time at 2$0^{\circ}C$ was, the faster the second increasing period was and the less the initial contents was. Lactic acid was increased 6~31 times from a little amount at the initial period. The higher the initial fermentation temperature was and the more the increasing content was. But malic acid which was abundant(55.1% of total nonvolatile organic acid) in the initial fermentation period was remarkably decreased in the palatable period. The change of the sulfides among the volatile compounds was remarkable. Methyl allyl sulfide which was a little in the initial fermentation period was remarkably increased in the final fermentation period, and the correlation coefficients between the content of methyl allyl sulfide and aroma in sensory evaluation were high. It could be suggested that the fermentation temperature should be set to 4$^{\circ}C$ after fermentating at 2$0^{\circ}C$ for 36 hours in the view point of keeping the Kakdugi taste and quality well because of high content of free sugar and nonvolatile organic acids.

  • This study was undertaden to investigate the effect of salted anchovy during Puchukimchi fermentation, Puchukimchi is a kind of Korean kimchi made with Puchu(Allium odorum L.). For this purpose, the Puchukimchi with 10%, 15% and 30% salted anchovy was investigated by measuring physicochemical, microbiological and sensory characteristics during fermentation at 5$\pm$2$^{\circ}C$ up to 60 days, In the palatable period, pH was remarkably decreased to the range of 4.8-5.16 and total acidity was increased 2-3 times more than that of initial period. Reducing sugar contents in Puchukimchi increased up to 22days and remarkably decreased. The changing pattern of vitamin C drawed sigmoidal curve, invreasing significantly in the palatable period. The content of lactic acid was a little in the initial fermentation period but increased 3-13 times more than that of the initial fermentation period in the palatable period. The content of malic acid and citric acid were decreased as the fermentation progressed. The contents of Ca, Mg and K was gradually decreased and Na was increased as the fermentation progressed in the same period. There were similiar changes in the number of lactic acid bacteria and total cell number. The score of overall taste, overall acceptability in evaluation during fermentation was high in order of 15%, 10%, 30% level of salt fermented anchovy.

  • The effects of salting degree of cabbage on the chemical, microbiological, textural changes and taste of Korean whole cabbage Kimchi fermented at $21^{\circ}C$ was studied. Low salted Kimchi (1.8% NaCl, soaking for 2 hr. in 20% brine) was showed higher total acdity than high salted Kimchi II(3.1% NaCl, Soaking For 8 hr in 20% brine) and III(2.9% NaCl, no soaking in 20% brine). The changes in growth of lactic acid bacteria was relevant to the salt content of whole cabbage Kimchi. Kimchi I was showed higher growth rate of Lactic acid bacteria and slower death rate constant of Lactic acid bacteria than that of Kimchi II and III. In palatability test, salty taste of Kimchi II, III was more salty than that of Kimchi I ($p{\leqq}0.01$) and total evaluation of Kimchi I, II was more palatable than Kimchi III ($p{\leqq}0.05$) at 3rd's day (optimum taste). Cutting force by Rheometer was well correlated with the salt content of Kimchi.
