Three sensory evaluations were conducted to assess the effect of food color on flavor identification. Elementary students and women university students served as subjects for three evaluations of hard candies, in order to assess color preference, to examine the effect of atypical color on flavor identification and to examine the acceptability of harmony between the color and the perceived flavor. Results showed that inappropriate coloring of the three flavored hard candies induced flavor responses that are normally associated with that color and decreased the acceptability. In addition, the acceptability of colorless candies is lower than that of colored candies. It is suggested from it that when there is no color on the product, even atypical color, it`s harder to identify the flavor and to get a high grade in its preference.

Sample frying oil was manufactured from simple mixing treatment of capsicum. butter flavor and silicone resin. the amount were 0.20, 0.15% ($\omega$/$\omega$) and 10 rpm in soybean oil, respectively. This frying oil was confirmed to improving of heat stability as well as removal effect of meat flavor. Frying oil obtained from treatment of capsicum and silicone resin was appeared, acid value and smoke point were 0.301, 232$\^{C}$, than its value in the non-treated soybean oil were 0.385. 220$\^{C}$, respectively, in the case of continuous frying at 185$\pm$2$\^{C}$. These effects were likely to according both anti-oxidation effect of capsicum and inhibition of free fatty acids and smoke production from anti-expansion of surface area in frying oil. Meat flavor and burnt flavor of oil in the frying oil and fried foods were weakened by treating of butter flavor(0.15%, $\omega$/$\omega$), this effect will be produced to new type\`s frying oil product.

In order to retain or remove the flavor components of onions, this study was performed to investigate the effect of seaweeds and adsorbents on volatile flavor components of onion juice by testing a sensory evaluation, measuring the amount of pyruvate and thiosulfinate, and investigating the changes of volatile components by SPME/GC. The main flavor compounds in raw onion juice were dipropyl tetrasulfide, 1-propenyl propyl trisulfide, methyl propyl trisulfide, dipropyl trisulfide. Volatile flavor compounds in onion juice treated with tangleweed, brown-seaweed, laver and celite showed a relatively decreasing tendency compared to untreated onion juice, but most of volatile flavor compounds in onion juice treated with activated charcoal and ${\beta}-cyclodextrin$ were removed. The result of the sensory evaluation with various materials for masking onion flavor showed a significant difference at the p<0.05 level. The amount of pyruvate and thiosulfinate treated with tangleweed, brown-seaweed, laver and celite showed little difference compared to untreated onion juice, but the amount of pyruvate and thiosulfinate treated with activated charcoal and ${\beta}-cyclodextrin$ decreased largely compared to untreated onion juice. As a result of the study, onion juice treated with tangleweed, brown-seaweed, laver and celite showed the effect of preserving the pungent taste and masking the onion flavor. Activated charcoal and ${\beta}-cyclodextrin$added to onion juice might have a role in removing the onion flavor by adsorbing volatile flavor compounds in onion.

We carried out separation and guantitation of flavor components by GC about essential oils extracted from deodorized corn oil at the different deodorizing temperature. Flavor components were detected total 16 kinds included aldehydes of 8 kinds, major components were propane, pentane, hexanal etc. These major components content was about 70~75% of the total flavor components. According to rise of deodorizing temperature, both ethane and aldehydes of 8 kinds content were in proportion to increase, but propane, pentane, hexane, octan, pentyl furan content were decreased by contraries, respectively. On the other hand, total flavor component content was appeared the lowest level at 245$^{\circ}C$ treating group, aldehydes content was in proportion to increase according to rise of deodorizing temperature. These phenomenons consider that the undesirable reactions such as partial auto-oxidation, degradation, polymerization and hydrolysis etc. by effecting factors of stripping steam and vacuum degree. Conclusively, deodorizing temperature under high temperature was undesirable for the minimization of off-flavor materials.

This study was conducted to evaluate the effect of dietary supplementation of anise flavor on the performance of lactating sows and suckling pigs at different weaning ages. A total of 120 sows (Landrace ${\times}$ Yorkshire) were used in this experiment. Sows were fed with a commercial lactation diet (60 sows) or diet with flavor (60 sows) during days 100 to 114 of gestation period and the whole lactation period. Piglets were allotted to 2 dietary treatments based on their initial body weight (BW) using a $2{\times}2$ factorial arrangement of treatments with 2 levels of anise flavor (0 or 0.5 g/kg) and weaning periods (weaned at 21 day or 28 day after birth). Sows fed with flavor supplemented diets had higher (p < 0.05) back fat and average daily feed intake (ADFI) at weaning, lower (p < 0.05) back fat loss than those fed with non-flavor diets. Sows weaned at 28 day had higher (p < 0.05) weaning back fat and lower (p < 0.05) back fat loss than those weaned on 21 day. During weaning, piglet average daily gain (ADG), ADFI, digestibility of dry matter (DM), nitrogen (N), and gross energy (GE) and fecal score were affected by anise flavor, respectively. In conclusion, dietary flavor supplementation could increase feed intake of lactating sows, improve growth performance and reduce weaning stress of piglets, especially effective in the early weanling piglets. Meanwhile, interactive effects were observed about the piglet performance between weaning ages and anise flavor supplementation after weaning.

Microencapsulation of flavor was carried out by molecular inclusion process using $\beta$-cyclodextrin (${\beta}CD$). ${\beta}CD$-flavor complex was prepared at various flavor-to-${\beta}CD$ ratios (1:6-1:12) to determine the effect of ${\beta}CD$ concentration on the inclusion efficiency. Maximum total oil retention and minimal surface oil content were obtained at flavors to ${\beta}CD$ ratio of 1:10. The physical properties and controlled release pattern of flavors from ${\beta}CD$-flavor complex were measured and compared with spray-dried microcapsules prepared using carbohydrate wall system. ${\beta}CD$-flavor complex showed higher total oil retention and surface oil contents, smaller mean particle size, lower moisture uptake, and higher oxidation stability than spray-dried microcapsule. Oxidative stability of flavor was correlated with hygroscopicity of wall materials. The controlled release mechanism was highly affected by temperature and characteristics of wall materials.

Sodium chloride is an important ingredient added to most of foods which contributes to flavor enhancement and food preservation but excess intake of sodium chloride may also cause various diseases such as heart diseases, osteoporosis and so on. Therefore, this study was carried out to investigate the effect of monosodium glutamate (MSG) as a salty flavor enhancer on the quality and sensorial properties of the NaCl/MSG complex and actual food system. For characterizing the spray-dried NaCl/MSG complex, surface dimension, morphology, rheology, and saltiness intensity were estimated by increasing MSG (0-2.0%) levels at a fixed NaCl concentration (2.0%). MSG levels had no effect of the characteristics of the NaCl/MSG complex, although the addition of MSG increased the surface dimension of the NaCl/MSG complex significantly (p<0.05). Furthermore, the effect of MSG on enhancing the salty flavor was not observed in the solution of the NaCl/MSG complex. In the case of an actual food system, model meat products (pork patties) were prepared by replacing NaCl with MSG. MSG enhanced the salty flavor, thereby increasing overall acceptability of pork patties. Replacement of NaCl with MSG (<1.0%) did not result in negative sensorial properties of pork patties, although quality deterioration such as high cooking loss was found. Nevertheless, MSG had a potential application in meat product formulation as a salty flavor enhancer or a partial NaCl replacer when meat products were supplemented with binding agents.

The masking effect of Chamnamul (Pimpinella brachycarpa) on meaty and fishy flavor was measured by sensory evaluation to investigate the usefulness of Chamnamul as a natural spice or herb. Shady air dried Chamnamul was utilized for sensory analysis. By the use of Chamnamul, the meaty flavor was significantly reduced in beef and pork. Chamnamul also showed a similar effect as black pepper on reducing meaty flavor. The use of Chamnamul also significantly reduced the fishy flavor of anchovy soup. When Chamnamul was added to rice gruel, rice odor was reduced but grassy odor remained strong.
