The intake of dietary salt through food now exceeds current nutritional recommendations and is thought to have negative effects on human health, such as the increasing prevalence of hypertension. This study was performed to investigate whether $W_1/O/W_2$ double emulsions can be used to enhance the saltiness of cheese without increasing the salt content ($W_1$ is distilled water or 1% abalone hydrolysate, and $W_2$ is 1% NaCl or 1% abalone hydrolysate + 1% NaCl solution). We also investigated the effect of adding abalone hydrolysate to the double emulsion as a saltiness enhancer. The cheeses were physico-chemically evaluated to determine curd yield, pH value, moisture content, color, texture, salt release rate, and sensory properties. No significant differences were observed in curd yield, pH value, moisture content, lightness, or redness between the cheeses made with and without the double emulsion. However, in the evaluation of salt release rate, fresh cheese made with double emulsion ($W_1$ = distilled water, $W_2$ = 1% NaCl + 1% abalone hydrolysate) was detected earlier than the control or the other treatments. In the sensory evaluation, fresh cheese made with the double emulsion showed higher scores for saltiness and overall preference than the control or the other treatments. We concluded that abalone hydrolysate encapsulated in a double emulsion ($W_1$ is water and $W_2$ is abalone hydrolysate and NaCl solution) could enhance the saltiness of fresh cheese while maintaining the same salt concentration, without altering its physical properties.

Comparisons between the Korean native pig(KNP: 75kg of slaughter weight and 240 days of age) versus Landrace(110kg of slaughter and 180 days of age) in dressing and lean meat percentages, compositions of fatty acids and amino acids and sensory evaluations on longissimus muscle are as below. Compared with Landrace, KNP had smaller percentages in dressing and lean meat percentages and a smaller backfat thickness. In retail cuts, KNP had greater percentages in shoulder butt, belly and picnic shoulder and smaller percentages in spareribs, ham and loin muscle. The KNP had greater percentages in crude fat, palmitic(C16:0) and linolenic(C18:3) acids and smaller percentages in oleic(C18:1) and linoleic(C18:2) acids, but total cholesterol content and ratios of saturated and unsaturated fatty acids and essential fatty acids did not differ between the two breeds. In amino acid composition, KNP had a greater percentage in lysine, but smaller percentages in most other amino acids. The KNP had a greater a*(redness) value in longissimus muscle(LM) color and a greater L*(whiteness) value in attached backfat color. Moreover, sensory evaluations on cooked LM showed that KNP had greater flavor, tenderness and springiness, which resulted in a greater overall acceptability. In summary, KNP, compared with Landrace, had smaller dressing and lean meat percentages, a smaller backfat thickness, greater percentages in popular retail cuts, greater percentages in intramuscular fat and an $\omega$-3 component linolenic acid, with no difference in cholesterol content, which, altogether, is considered to be more beneficial for human health.

Kaempferia parviflora (Krachaidam, Zingiberaceae) is used as a traditional Thai medicine for treating various ailments, including allergy, fatigue, sexual dysfunction, and ulcer. Moreover, it is also used to promote longevity and as a nerve tonic. The aim of this study was to develop functional yoghurt containing Kaempferia parviflora and to examine the physicochemical characteristics of yoghurt supplemented with different concentration of K. parviflora. To this end, we examined the pH and sensory evaluation of yoghurt containing K. parviflora. The pH of this yoghurt decreased whereas the TA increased with incubation time (up to 5 h) without altering the amounts of K. parviflora added. In the sensory evaluation, the taste, flavor, color, and overall acceptability decreased in proportion to the amount of K. parviflora added. Among the experimental group, high scores were achieved by yoghurt containing 1% K. parviflora compared with that by the control group. We conclude there is an urgent need for additional research on the production of this multi-functional yogurt (with properties including anti-obesity and anti-inflammatory), using an optimum concentration of K. Parviflora.

This study assessed the quality of barley Dasik manufactured, according to traditional methods, with various levels of Maesil (Prunus mume) extracts at weight percentages of 0% (BD1), 10% (BD2), 20% (BD3), 30% (BD4), 40% (BD5). The Dasik were analysed with proximate analysis, a sugar content analysis, Hunter's color value test, mechanical characteristics test and a sensory evaluation. Increased ratios added Maesil extracts led to the moisture content, crude ash, and crude fat to significantly increase (p<.001). 10% (BD2) had significantly higher levels of crude protein (p<.01). Sugar contents was highest in 0% (BD1) and decreased as the amount of added Maesil extracts increased. This increase also led to higher L-values and b-values of chromaticity (p<.001) and the a-value of 0% (BD1) was significantly higher than the sample groups (p<.001). Changes in texture profile analysis, hardness and gumminess values were highest in the control group and the values of those in the sample group decreased with increasing amounts of Maesil extract (p<.001). It should be noted that, among the samples evaluated, barley Dasik that contained 10% Maesil extract (BD2) had the highest commercial value.

A band function model paired comparison method (BMPC method) is a kind of a paired comparison methods. Considering the human ambiguities, the BMPC method expressing the human judgment characteristics as a monotonous increase function with some width. Since function types are not specified in a BMPC method, the solution is obtained from inequalities, and the solution is given as a domain. To solve the simultaneous inequalities, the sequential renew method is used in the previous BMPC method. However, the sequential renew method requires much computational effort and memories. Generally, in BMPC method, it is able to solve only a paired comparison table which has less 12-13 samples. For that purpose, a new fast solution algorithm is required. In this paper, we proposed a new “search vector method” which renews the solution domain without creating new edge vectors. By using the method, it is able to decrease the necessary memory spaces and time to solve. The proposed method makes it able to solve more than 15 samples paired comparison inspections which are impossible to solve by previous method.

In this study, differences of texture image and preference for men's suit fabrics according to mechanical properties, hand and fabric information were investigated. 55 subjects evaluated texture image and preference of 12 kinds of wool blended fabrics. For statistical analysis, t-test and pearson correlation coefficients were used. The results were as follows: Most of mechanical properties effected on texture images, and bending property and shearing property were effected on tactile preference and purchasing preference. For hand, objective hand values showed correlations with subjective texture images and preferences, but THV had almost no correlations. In sensory images according to presence of fabric information, fabrics were evaluated thinner, lighter, more pliable and smooth by cognition of wool blending ratio. For sensibility images, fabrics were evaluated more refined, intellectual, dignified and less practicable after recognize of wool blending ratio. In preferences, tactile preference was increased and purchasing preference was decreased after recognize fabric information. Therefore, significant differences of texture image and preference were observed according to presence of fabric information.
