  • The Microbiological, chemical and sensory analyses were carried to evaluate the quality of commercial salted and fermented seafoods and to establish a standardization. The results showed that amino nitrogen(AN) and volatile basic nitrogen(VBN) contents were appropriate in evaluating the quality of shrimp jeotkal. In the range of $150{\sim}300\;mg%\;and\;25{\sim}70\;mg%$, AN and VBN contents were highly correlated to sensory scores, respectively. In the case of squid jeotkal, pH and VBN contents were appropriate to evaluate quality. The coefficients of the correlation between pH and sensory evaluation was 0.84 and the sensory acceptability was high and above pH 6.0. In addition, the coefficients of the correlation between VBN contents and sensory evaluation was 0.95, and the sensory acceptability was high but below 30 mg%. In the case of shell-fish jeotkal, the coefficient of the correlation between VBN content and sensory evaluation was 0.94, and sensory acceptability was high but below 40 mg%.

  • This study examined the quality characteristics of Gondre tofu containing 0, 0.1, 0.2, and 0.3% Cirsium setidens powder. Quality and sensory tests of Gondre tofu were performed. The yield rate of tofu decreased with the addition of Cirsium setidens powder. The pH of tofu decreased after the addition of Cirsium setidens powder. During 8 days storage, the addition of Cirsium setidens powder to tofu did not effectively inhibit the number of total aerobic bacteria. The L, a and b values of tofu decreased with increasing amount of Cirsium setidens powder added. In the texture properties, the hardness, cohesiveness, gumminess and brittleness increased, whereas the springiness decreased. The results of sensory evaluation showed that tofu containing 0, 0.1, and 0.2% Cirsium setidens powder had a higher taste, texture preference and overall acceptability than 0.3% Cirsium setidens powder. Therefore, the addition up to 0.2% Cirsium setidens powder positively affects the sensory evaluation of Gondre tofu. The addition 0.2% Cirsium setidens powder might be considered the most appropriate choice for manufacturing Gondre tofu.

  • This study was conducted to develop an optimal composite recipe of nutritional cookies containing Chinese artichoke (Stachy sieboldii Miq) powder. Rice powder was partially substituted with Chinese artichoke (Stachy sieboldii Miq) powder to reduce its content. The optimal sensory composite recipe was determined by 3 concentrations of Chinese artichoke (Stachy sieboldii Miq) powder, butter, and sugar, using the central composite design. In addition, the mixing condition of Chinese artichoke (Stachy sieboldii Miq) powder rice cookies was optimized by subjecting the cookies to a sensory evaluation and instrumental analysis using the response surface methodology (RSM). The effects of the addition of the three variables on the quality of Chinese artichoke (Stachy sieboldii Miq) rice powder cookies were assessed in terms of color, hardness, sweetness and sensory evaluation. The results of the sensory evaluation produced values very significant for flavor, texture, sweetness, appearance, and overall quality (p<0.05). The results of instrumental analysis showed significant values in moisture content, spreadability, sweetness (p<0.01), lightness, redness, and hardness (p<0.001). As a results, the optimal sensory ratio of Chinese artichoke (Stachy sieboldii Miq) rice cookies was determined to be Chinese artichoke (Stachy sieboldii Miq) powder 4.22 g, butter 120.00 g, and sugar 130.00 g.

  • The correlation between microbiological and sensory quality indexes was investigated for Korean seasoned side dishes stored under chilled conditions, by using both published data and experimental evaluation. Aerobic bacterial counts on the perishable Korean side dishes showed high inverse correlation with sensory quality and could also be regarded as a main cause of sensory quality deterioration. Therefore, monitoring or estimating the microbial growth on these products should be an effective means for estimating and extending their shelf life.
