Four-dimensional response surface methodology was applied to determine the optimum preparation conditions and to monitor sensory qualities of canned oyster mushroom during preparation. The optimum preparation conditions predicted for each corresponding sensory parameter of canned oyster mushroom were 181.29 g of oyster mushroom 205.36 ml of solution and 6.49min of roasting time for color, 214.01g, 195.79ml and 5.07min for appearance, 227.71g, 224.26ml and 6.50min for flavor, 250.30g, 183.63ml and 17.32min for taste, 211.59g, 178.21ml and 17.79min for mouth-feel, 249,.02g, 188.79ml and 17.80min for overall palatability of canned oyster mushroom, respectively. The optimum conditions, which satisfied with all sensory properties of canned oyster mushroom, were 240g, 200ml and 17min for content of oyster mushroom, content of solution and roasting time, respectively. Sensory scored predicted at the optimum conditions were in good agreement with experimental ones.

The purpose of this study was to analyze the physiochemical properties of blackberry fruit beverage(BFB) and to develop a descriptive analysis procedure for evaluating the sensory characteristics of BFB. The amount of soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of BFB were determined. All BFB samples demonstrated significantly different physicochemical properties(p<.01). Ten highly trained panelists identified the following eleven sensory attributes in the BFB and defined by standardized terminology for each attribute; turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, throat hit, refreshing, as well as astringent grade for textural characteristics. There were significant differences in all the eleven sensory attributes of the BFB samples(p<.001). Descriptive terminology used in the BFB analysis was capable of classifying the sensory attributes of the BFB. Based on these results, the analysis method and sensory evaluation techniques used in this study could be reasonably applied to other fruit beverages for establishing similar physiochemical characteristic and descriptive sensory attributes.

The purpose of this study was to determine gain the most desirable mixture ratio for the ingredients of Backhapbyung. Sensory examination and mechanical test were conducted on the texture, water contents and color degree of Backhapbyung with various ratios of liliibulbs powder and sugar added to nonglutinous rice flour. The results of sensory evaluation showed that Backhapbyung composed of put 8% (24g) liliibulbs powder, 40g sugar, 40ml water and 276g nonglutinous rice flour had the highest overall score in terms of acceptability, after-swallowing and taste of flavor, and overall quality preference. Overall among the recipes tested, that with 6% (24g) liliibulbs powder, 40g sugar, 40 ml water and 282g nonglutinous rice flour showed the highest marks in springiness, cohesiveness, gumminess and chewiness. The moisture content was 33.54% nonglutinous rice flour, and 11.8% liliibulbs powder. The overall quality of sensory examination for bitterness was positively correlated with the hardness of sensory examination and the mechanical examination for adhesiveness. The overall quality of sensory examination for chewiness was positively correlated with the moistness of sensory examination and the mechanical examination for cohesiveness. From the above results, the best mixture ratio of Backhapbyung, with a moisture content of 37.18%, is 8% (24g) of liliibulbs powder, 40g sugar, 40ml water, and 3g salt and 276g nonglutinous rice flour.

The principal objectives of this study were to analyze the physiochemical properties of four mulberry fruit beverages (MFBs) and develop descriptive analysis procedures for evaluation of their sensory characteristics. Soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of MFBs were determined. All MFB samples showed significantly different physicochemical properties ($p$<0.01). Ten highly trained panelists identified the following 11 sensory attributes in the MFBs and defined the terminology for each attribute : turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, and throat hit, refreshing, and astringent for textural characteristics. There were significant differences in the 10 sensory attributes among the MFB samples ($p$<0.001). In color, the value of MFB3 was significantly higher than those of others ($p$<0.05). In taste and overall acceptance, the values of MFB2 were significantly higher than those of others ($p$<0.01, $p$<0.001). Descriptive terminology of the developed MFBs could explain the sensory attributes of the samples according to this result. Based on this, proper analysis and sensory evaluation techniques could be applied to other fruit beverages to establish their physiochemical characteristic and descriptive sensory attributes.

Fermentation of wort was investigated with an ultimate goal to develop a fermented beverage rich in prebiotics and functional ingredients as well as desirable in flavors. Wort was fermented with Leuconostoc citreum HJ-P4 originated from kimchi and subjected to sensory descriptive analysis. L. citreum HJ-P4 produced various organic acids (e.g., lactic acid, acetic acid) as well as functional sugars (e.g., mannitol, panose) during wort fermentation. The concentration and ratio of lactic acid and acetic acid were significantly influenced by roasting conditions of malts used for wort preparation and aeration conditions during fermentation. The concentration of mannitol and panose varied depending on the sucrose content of wort and aeration conditions. Sensory characteristics of the fermented worts were clearly differentiated according to the roasting conditions of malts used for wort preparation and aeration conditions during fermentation. These results indicate that metabolite concentration of fermented wort and its sensory properties can be manipulated with roasting conditions of malts and fermentation conditions.

This study was aimed to compare the texture and sensory properties of Cream cheese and cholesterol-removed Cream cheese made from the whole milk powder (CRWMP) during storage at $7^{\circ}C$ for 4 wk. The cholesterol reduction by crosslinked ${\beta}$-CD was about 92% in CRWMP. In texture studies, hardness, gumminess, and chewiness had increased during the storage period of 4 wk in both cheeses, irrespective of treatment. In the sensory properties, cooked milk flavor was found to have decreased, whereas sourness had increased with increasing storage period of 4 wk in whole milk powder Cream cheese. On the basis of our results, we conclude that the cholesterol removal in CRWMP does not cause any adverse effect on the texture and sensory properties of Cream cheese made with whole milk powder.

An attempt is made to predict the shelf life of seasoned anchovies packaged with laminated film, composed of polyethylene terephthalate (PET) and ethylene vinyl alcohol (EVOH). First, a descriptive sensory analysis is carried out to determine the principal sensory quality index in seasoned anchovies. Then, the physicochemical quality index with high correlation to the principal sensory quality index is determined accordingly. Subsequently, with the physicochemical quality index, the shelf-life is estimated by using the Arrhenius equation. As for the sensory quality index, 'color' is determined as a principal sensory quality index. For all samples stored at 3 different temperatures (25, 35, $45^{\circ}C$), it is observed that the sensory score is shown to be over 2.5 until 60 days of storage period, which is the lowest acceptable level. In addition, the b-value, as a physicochemical quality index, is determined to have a high correlation to the sensory quality index. Further, the activation energy and the Q10 value for the b-value by the Arrhenius equation is found to be 11.24 kcal/mol, 1.385~2.011, respectively. Thus, it can be concluded that the shelf life of seasoned anchovies packaged with PET/EVOH film is estimated to be 279.44 days when stored at $20^{\circ}C$.
