This paper considers an a, pp.ication of one of the sensory engineering's techniques, extraction and categorization of the sensory words, to the product of cars. The fourty five (45) sensory words are extracted in three steps. Two groups, which are characterized by whether possessing a car or not and each group consisting of one hundred persons randomly selected from the twenties or thirties, are asked to answer the questionaires with the extracted words in the five-grade semantic differential. The factor analysis is used to categorize the extracted sensory words, and shows that the words can be grouped into four categories.

Objective: This study evaluated the supplementary effect of higher concentrations of various disaccharides on processing yield, major physicochemical properties, and sensory attributes of Chinese-style pork jerky (CSPJ). Methods: CSPJ samples were prepared by marinating sliced ham (4 mm) with three dissaccharides, including sucrose, lactose, and maltose, at 0%, 15%, 18%, 21%, and 24%. Subsequently, the CSPJ samples were dried and roasted. The moisture content, water activity, crude protein, moisture-to-protein ratio, pH, processing yield, shear force, color, and sensory attributes of the CSPJ samples were evaluated. Results: The quality characteristics of CSPJ samples prepared with sucrose were more acceptable. By contrast, CSPJ samples prepared with lactose showed the lowest scores. However, the processing yield and moisture content were the highest for CSPJ samples prepared with lactose, which may be associated with improved benefits for cost reduction. Furthermore, sucrose and lactose supplementation resulted in contrasting quality characteristics; for example, CSPJ samples with sucrose and maltose supplementation had higher sensory scores for color than samples with lactose supplementation. Additionally, most quality characteristics of CSPJ samples with sucrose supplementation contrasted with those of the samples with lactose supplementation; for example, the samples with sucrose supplementation had higher scores for sensory attributes than those with lactose supplementation. Conclusion: Sucrose supplementation up to 21% to 24% was associated with the highest overall acceptability scores (5.19 to 5.80), enhanced quality characteristics, increased processing yield, and reduced production cost.

Seolleongtang, a traditional broth in Korea, is expected to become a hot global item for its unique flavor and healthiness. In this study, the correlations between sensory attributes and physicochemical characteristics were studied for the popular seolleongtang stock products through descriptive analysis, sensory evaluation and analysis of salt, soluble solid, protein, viscosity and color for the quality control. Our results indicate that color, concentration, viscosity, and freshness are important attributes in evaluating the quality of seolleongtang stock. There were significant differences between preference and sensory attributes among the stock products. Significant correlations were found between flavor and texture and overall acceptability, as well as beany odor and aroma. Preference and physicochemical aspects also correlated, and indicate that a range of salt, solubility, and viscosity are applicable as quality control factors in seollengtang stock.

Quality changes of cooked meat products are dependent upon cooking temperature and heating methods. Pork ham is the most preferred pork dish using pork hams in South Korea although it is not suited to various cooking methods because its low fat content does not provide desirable physiochemical and sensory properties to consumers. Therefore, the objective of this study was to evaluate the effect of four different cooking methods on pork legs by comparing Ocoo, Sous-vide, steaming, and boiling technique at $80^{\circ}C$ and $100^{\circ}C$. Ultimately, the most effective cooking method and temperature to improve the quality of cooked pork hams was investigated. As the results of texture analysis, the samples cooked using Ocoo and Sous-vide methods showed higher springiness and cohesiveness than those using steaming and boiling methods. For the sensory evaluation, participants liked the hardness, juiciness, chewiness, tenderness of the samples using the OC method, resulting in the highest overall acceptance rate. The results of this study showed that using Ocoo or Sous-Vide cooking methods can improve the quality of cooked pork hams in both physicochemical and sensory properties.

The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour and on quality properties color cooking quality textural and sensory properties and reducing microbial population of LL(Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption stability and breakdown were increased by ginseng. The whiteness of Ll nodles manufactured with ginseng was lower than that of control The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng weight of cooked LL noodles was decreased but volum was appeared in ice versa,. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control Total count of microorganism of Ll noodles manufactured with ginseng were decreased during storage at 3$0^{\circ}C$ Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.

The purpose of this study was to analyse serving size, plate waste, and sensory evaluation on menu of university foodservice. This study was conducted in three restaurant of one university for 14 days, 1995. The serving size of food was measured by weighing machine. The plate waste of food was calculated by the aggregative selective plate waste measurement technique. Questionnaires of sensory evaluation were developed and hand-delivered at three restaurants. Rating criteria of sensory evaluation were appearance, taste, temperature, color, flavor, texture and overall quality. The plate waste of side dish were 35.5%, 42.5%, and 39.2% in A, B, and C restaurants. The plate waste of kimchi were 46.8%, 36.3%, and 55.9% in A, B, and C restaurants. So, university foodservice manager should concern quality of side dish and kimchi. The score of fried food in sensory evaluation was low. So, batch cooking was needed. The score of rice in sensory evaluation of C restaurants was very low. Therefore, steam ice cooker in C restaurants should be changed by gas automatic rice cooker.

This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). Sensory scores were examined for ssanghwa beverages containing different levels of glucosyl stevia, aspartame, and acesulfame-K(0, 50, and 100%, respectively) in place of HFCS. The results showed that sensory scores were not significantly different for the beverages containing different levels of acesulfame-K, including aftertaste, ssanghwa taste, and overall eating quality. In contrast, the sensory scores of beverages containing 0 and 100% glucosyl stevia were significantly different. Data were also gathered comparing the sensory scores of beverages according to the different types of sweeteners. Bitter taste and astringency were not significantly different between the beverages sweetened with HFCS, KP(containing 50% acesulfame-K and 50% aspartame), SP(containing 50% glucosyl stevia and 50% aspartame), and SK(containing 50% glucosyl stevia and 50% acesulfame-K), respectively. Finally, aftertaste and overall eating quality were not significantly different between the HFCS and SP sweetened beverages.

The purpose of this study was to investigate the quality characteristics of cookies containing Ligularia fischeri powder (0, 1, 2, 3, 4%) substituted for flour. This study measured the density, pH, spread ratio, volume, color values, hardness, and sensory properties of cookies. The pH of cookie dough significantly decreased in response to addition of Ligularia fischeri powder (LFP) at all levels. The spread factor of cookies also significantly increased with higher LFP content. In addition, Hunter's color L, a, and b values significantly decreased with increasing LFP content. According to hardness measurement, substitution of 1~4% LFP resulted in increased hardness compared to the control. In the sensory evaluation, sensory scores for color, flavor, and overall acceptability were highest in 2% Ligularia fischeri powder cookies. Thus, our results suggest that the optimum amount of Ligularia fischeri powder added to cookies was 2%. These results suggest that Ligularia fischeri powder can be applied to cookies to achieve high quality and functionality.
