The purpose of this study was to evaluate the relationship between periodontal disease and halitosis, and to develop a detail clinical protocol for assessing halitosis in animals. We measured the periodontal disease parameters, the degree of halitosis using organoleptic scale method and the concentration of volatile sulfur compounds(VSC) using portable sulfide monitor($Halimeter^{TM}$). In this study, VSC levels by $Halimeter^{TM}$ were found to be significantly associated with periodontal disease parameters(plaque index, calculus index)(P<0.05). We also found that conscious sedation did not affect the measurement of VSC levels.

Scoring difference test was applied for determining the organoleptic characteristics of mushrooms which was ${\gamma}-irradiated$ in connection with the shelf-life extension. Irradiation at 1 to 3kGy caused a significant softening of mushroom tissue (p<0.05), but it showed no immediate influence on the overall appearance, flavor and taste of mushrooms. After 17 days of storage at $9{\pm}1^{\circ}C\;and\;80{\pm}7%$ RH, 2 to 3 kGy-irradiated mushrooms were significantly better than the nonirradiated control in the sensory properties such as appearance, texture, flavor and taste (p<0.01). Organoleptic scores have shown that the irradiated samples are acceptable more than 17 days, compared to 7 days in the nonirradiated control.

Five different commercial chungkukjang powders (A$\sim$E) were compared based on their physicochemical, organoleptic and functional properties. The proximate composition of the five samples ranged from 6.07 to 8.54% in moisture, 15.31 to 27.07% in crude protein, 20.19 to 24.75% in crude lipid, 34.84 to 52.41% in carbohydrate, and 3.69 to 5.26% in ash. The pH of the samples ranged from 5.58 to 6.11, and Hunter's colors showed 70.01$\sim$77.22 for L value, 0.91$\sim$4.64 for a value and 23.72$\sim$31.00 for b value depending on the product. The microbial counts were 8.16$\sim$g.60 log CFU/g for aerobic bacteria, $\sim$4.16 log CFU/g for yeasts & molds, and 1.07$\sim$3.88 log CFU/g for coliforms. The contents of reducing sugars and amino-N were 1.89$\sim$2.41% and 2.83$\sim$7.31%, respectively. Free amino acids were mainly composed of glutamic acid, valine, leucine, phenylalanine, and lysine. The amounts of total phenolics and total flavonoids were 108$\sim$302 mg% and 2.73$\sim$9.41, respectively, with some variations in the products. However, the isoflavone contents, which were composed of genistein (63.26$\sim$217.16${\mu}g/g$), daidzein (58.24$\sim$166.65${\mu}g/g$), genistin (2.66$\sim$55.68${\mu}g/g$), and glycitein (12.26$\sim$17.82${\mu}g/g$), were apparently different per product. The sensory scores for color, smell, taste and overall preference for the five chungkukjang products, which were evaluated by panels in their 20's and 30's using 7-point scoring test, ranged from 3.20 to 4.05.
