Purpose: This study analyzed and compared the physico-chemical and affective properties between mackerels cooked by an electric pan and under superheated steam. Methods: Mackerel were cooked by an electric pan ($95^{\circ}C$) for 10 min and mackerel cooked under superheated steam ($250^{\circ}C$) for 5 min to be internal temperatures of $75{\pm}5^{\circ}C$ and tests to measure proximate composition, color values, texture profiles, microorganism counts and sensory acceptance were performed. Results: The moisture contents were 60.30% and 73.81% in mackerels cooked by electric pan and under superheated steam, respectively. The rate of weight loss in mackerel cooked by electric pan was 39%, whereas it was 29% in mackerel cooked under superheated steam. Mackerel cooked under superheated steam exhibited more yellowness, higher springiness, cohesiveness, gumminess, chewiness, and resilience with more acceptable preferences (appearance, odor, taste, and texture) compared to the mackerel cooked by electric pan. Conclusion: The application of superheated steam technology to fish products could reduce the cooking time and nutritional loss. Also, it could produce highly preferred fish products compared to that prepared by conventional electric pan.

Sensory characteristics of cooked rites of one waxy variety and three nonwaxy varieties, Akibare (Japonica), Milyang 23 (J/Indica) and Milyang 30 (J/Indica) were evaluated in terms of odor, taste, appearance and texture. Sensory evaluation of cooked rites indicated that the cooked waxy rice was more watery, gloss, sticky, smooth and gummy in appearance and texture than nonwaxy cooked rites. Among the nonwaxy rites, Akibare was well balanced in all of the 12 descriptions of sensory quality. Milyang 30, generally recognized as having inferial eating quality, had the poorest quality in texture and appearance. The ratio of water addition to rice for cooking affected significantly to texture and appearance of cooked rice while the flavor remained comparatively unchanged.

Objective: This study was conducted to investigate the effects of adding oregano (Origanum syriacum L.) and germander (Teucrium polium L.) to poultry diets individually and/or in combination: i) on cooked chicken meat quality and storage stability, ii) to compare this effect with those of the synthetic antioxidant butylated hydroxyanisole (BHA) and with the normal basic diet (Control: without supplements). Methods: Broilers (140 birds) were raised for 21 days and then equally divided into five different treatment groups of 28 birds each. The dietary treatments were as follows: i) control; ii) germander (GER, 1.5%); iii) oregano (ORE, 2.5%); iv) combination of GER and ORE (CM, 1.5%, and 2.5%); v) BHA (0.02%). Meat patties from the five treatments were prepared, cooked, and stored at 4℃ prior to analysis. During storage, samples were measured for thiobarbituric acid-reactive substances (TBARS) and total carbonyl levels at 0, 4, and 7 days. In addition, cooked thigh meat was prepared separately to evaluate cooking loss and sensory attributes. Results: The CM dietary treatment showed the highest antioxidant effect, with decreasing TBARS values (breast and thigh meat) throughout the storage time (4 to 7 days). Furthermore, ORE showed a higher antioxidant effect, decreasing the rancidity development (TBARS values), compared to the GER during the storage period (days 0 to 7). The anti-carbonyl effect of the CM supplement was the highest among all treatments from day 0 to 7. Generally, the antioxidant effect of GER was lower compared to that of ORE and BHA alone. The CM treatment most significantly decreased off-odor and rancidity development, with the lowest oxidation odor scores. Conclusion: The results indicate that the combination of oregano and germander in the diet of boilers improves meat quality and prolongs shelf life.

Fuzzy reasoning was applied to sensory evaluation of cooked rice. A sensory attribute diagnostics was done in terms of tour kinds of attributes-texture, taste, odor and appearance which determine overall palatability. First, rating for the contribution level of each attribute to the overall palatability was asked as one of five scales-very important, important, moderate, slight and very slight. Secondly, the preference level of each attribute for a cooked rice sample was asked as one of five hedonic scales-excellent, good, fair, poor and very poor. Thirdly, the results of the scales were converted into fuzzy values and operated by fuzzy reasoning. Finally, the contribution and preference levels of the attributes were composed to infer the overall palatability of cooked rice sample.

In order to elucidate a mechanism responsible for the development of the odor characteristics of cooked, desirable-flavored shellfish, oysters were extracted using various solvents and the resulting extracts were evaluated organoleptically after cooking. The 80% aqueous methanol extract was found to produce a desirable cooked flavor. This oyster extract was fractionated using ion-exchange column chromatography and dialysis, and each of the fractions was subjected to cooking, followed by organoleptic evaluation. The outer dialysate fraction such as acidic and amphoteric water-soluble fractions produced a cooked oyster flavor. The volatile flavor compounds identified from cooked oyster included 29 hydrocarbons, 20 alcohols, 16 acids, 12 aldehydes, nine nitrogen-containing aromatic compounds, eight ketones, five furans, three esters, three phenols, and one benzene.

The physicochemical and sensory characteristics of commercial film-packed soybean sprouts from domestic cultivars were investigated. The hardness of the cotyledons was higher than that of the hypocotyls in fresh and cooked soybean sprouts (Kongnamulmuchim). Furthermore, the color determination showed that the hypocotyls and cotyledons of the soybean sprouts had a light green color that was not eliminated by cooking. The acceptability of fresh soybean sprouts was negatively correlated with a beany odor, beany taste, and grassy taste, but positively correlated with a nutty odor, nutty taste, and sweet taste. In addition, the acceptability of boiled soybean sprouts was negatively correlated with a beany and grassy taste, and positively correlated with a nutty odor and taste. Furthermore, the acceptability of cooked soybean sprouts was negatively correlated with a beany odor, beany taste, grassy odor, and grassy taste, while it was positively correlated with a nutty odor and taste. Finally, the lipoxygenase activity of the cotyledons was higher than that of the hypocotyls in fresh and boiled soybean sprouts.

The purpose of this study was to determine the best cooking condition for salted-dried flathead by sensory evaluation. Raw flathead and 3 different kinds of salted(2%, 4%, 6%)-dried flathead were cooked by various methods such as steaming, boiling, baking and different cooking times(5, 10, and 15min). The results of this study were as follows: 1. In steamed samples, the meaty flavor was significantly related with brown color, cooled level, and softness at 5% level. 2. In boiled samples, meaty flavor was significantly related with cooked level, moistness, and fishy odor at 5% level. 3. For broiled samples, meaty flavor was significantly related with fishy odor, meaty aroma, and bitter taste at 1% level. 4. The best cooking conditions determined by a quantitative descriptive analysis(QDA) were steaming 6% salted-dried samples for 5min, and boiling or broiling 6% salted-dried samples for 10min. The most favored cooking method was broiling. 5. In comparison of the samples by QDA, 2% salted-dried samples cooked 15 min gave better scores in the order of boiled > overall score > steamed > broiled, 4% samples cooked 5min were boiled > steamed > overall score > broiled, and 6% samples showed similar scores among all conditions. The 6% samples cooked for 5min gave high scores in 7 terms of QDA in steaming, and 6% samples cooked for 10min for boiled and baked.

The effectiveness of four air fresher (AF) systems was evaluated with respect to their removal efficiencies against offensive odorants. For this purpose, malodorous species were generated by exposing freshly cooked foods emitting odorants with levels moderately above their respective threshold values in a confined room. The deodorization efficiency of the four AF systems was then tested for a period of 30 min by estimating the extent of reduction in odorant levels after the operation of each AF. The removal efficiency of the four AF units against each odorant was evaluated as follows: (1) between AF products from different manufacturers, (2) between odorants and ultrafine particulate matter ($PM_{2.5}$), and (3) between operation and natural degassing. The average sorptive removal of odorants was generally <80% and considered less effective or non-effective relative to $PM_{2.5}$. Further examination of odor reduction, if evaluated in terms of odor indices like odor intensity (OI) and odor activity value (OAV), recorded a mean of 33% and 87%, respectively. The overall results of this study confirmed that all tested AF units were not effective to resolve odor problems created under our testing conditions.

The objective of this study was to investigate taste profiles and the correlation of Doenjang soup solution prepared with three different temperatures (5, 25, $45^{\circ}C$) and using an electronic nose (e-nose), electronic tongue (e-tongue), and descriptive analyses by trained panelists. A total of 17sensory attributes were generated from the descriptive analyses for the Doenjang soup solution. There were significant difference among the samples in the cooked soybean flavor, the cooked soybean odor, the soy sauce odor, the sweet odor, the sweet taste, and the sweet aftertaste attributes. The intensities of these sensory attributes tended to increase as the serving temperature of the Doenjang soup solution increased. There were seven volatile compounds detected by the electronic nose: ethanol, propanal, 2-methylpropanal, ethyl acetate, 3-methylbutanal, and beta-pinene. The intensities of the volatile compounds increased as the temperature of the Doenjang soup solution increased. On the other hand, the intensities of the basic tastes by the e-tongue decreased as the temperature of the Doenjang soup solution increased. In conclusion, the e-nose, e-tongue, and descriptive analysis results showed different correlations depending on the temperature of the Doenjang soup solutions.
