This study was conducted to evaluate sensory properties of sugar cookie containing sucralose. Relative sweetness of sucralose to sucrose in a cookie system was examined with paired comparison tests and the result was applied to low calorie cookie preparation using polydextrose as a bulking agent. Physical and sensory properties and consumer acceptability of sugar cookies containing various levels of sucralose and polydextrose were evaluated. Relative sweetness of sucralose to sucrose was 700 times in sugar cookie. Instrumental hardness and fracturability increased as the levels of replacement with sucralose increased. Spread ratios of sugar cookies where sucrose was partially and totally replaced with sucralose and corresponding amount of polydextrose were higher than that with sucrose only. Intensities of bitter taste, salty taste, hardness and molar packing of sugar cookies where sucrose was entirely replaced with sucralose and polydextrose were higher than that those of the other cookies. Acceptability test indicated 75% replacement with sucralose and adequate amount of polydextrose can be used without harming overall, appearance and flavor acceptability while texture acceptability was slightly lower.

To develop a new type of surimi with added citrus fruits, we examined the colors, textural properties and sensory evaluations of surimi after production. In the folding test, all samples had good flexibility, which suggested that addition of citrus fruits did not influence the flexibility of surimi. The pH in surimi samples was, in increasing order: lemon(Citrus limon), citron(Citrus junos), tangerine(Citrus unshiu), cumquet(Fortunella japonica var. margarita), and control. The pHs of each citrus fruits and the surimi with added citrus fruits were similar. Lightness increased in the following order: lemon, cumquet, control, citron, and tangerine surimi. Redness was high in the following order: tangerine, cumquet, control, citron, and lemon surimi. Yellowness increased in the following order: tangerine, cumquet, citron, lemon, and control surimi. There were no significant differences between lemon and control surimi. The hardness of surimi was highest in lemon, followed by citron, tangerine, cumquet, and control surimi. Although control surimi was the lowest, there were no significant differences among the samples. In terms of springness, it increased in the following order: tangerine, citron, control, lemon, and cumquet, but there were no significant differences among the samples. In sensory evaluation, overall acceptability decreased in the following order: cumquet, tangerine, control, citron, and lemon. Surimi containing cumquet got the best score in colors, textural properties, and taste except flavor. All samples got positive results in sensory ova luations, except for textural properties and taste of lemon and citron. Here, we confirm that surimi can be made with added citrus fruits, although we should examine in detail the quantities of added lemon and citron in a later study.

Fruit juices such as grape juice are associated with healthy products by consumers because of the many health benefits they provide. Farm produced (FPGJ) and commercially produced grape juice (CPGJ) in South Korea were compared and studied through the evaluation of their physicochemical, functional, and sensory properties. The results of this study show that FPGJ's physicochemical properties are more varied than CPGJ. The pH, titratable acidity, and total soluble solids of FPGJ were higher than CPGJ. FPGJ had a higher mean value for total phenolics ($2,558.20{\pm}50.06\;mg/L$ GAE), total flavonoid ($3,236.80{\pm}56.11\;mg/L$), total anthocyanin ($559.88{\pm}3.51\;mg/L$), and radical scavenging activity (86.48%) than CPGJ, although the differences were significant only with regard to total flavonoid and total anthocyanin. This study also demonstrates that CPGJ is preferred in terms of sensory evaluation. These properties may be used as a basis for the optimization of processing to produce a higher quality grape juice.

This study examined the quality characteristics of noodles prepared with Pleurotus (P.) eryngii paste. Different ratios of P. eryngii paste were added to wheat flour(15%, 30%, and 45%) in the noodle formation. Then, the noodles were evaluated in terms of their cooking, color, texture properties, and sensory properties. The weight and water absorption of the cooked noodles increased with increasing P. eryngii paste content, but the turbidity of cooking water decreased. According to texture profile analyses both the cooked and uncooked and cooked noodles had significant increases in springiness and cohesiveness with the addition of P. eryngii paste. And when compared to the control, hardness and gumminess were significantly lower in the samples containing P. eryngii paste. The lightness, redness, and yellowness of the cooked and uncooked noodles increased with increasing with increasing P. eryngii paste content. Finally sensory evaluation results indicated that the noddles containing 30% and 45% P. eryngii paste had higher quality as compared to the other samples. Overall the results suggest that P. eryngii paste is effective for improving the texture and quality of noodles.

Low-fat sausages were prepared with various meats to investigate the effect of the addition of oatmeal at 10% as a fat substitute. The sausages were made with beef, pork and chicken after trimming the visible fat, and the physical and sensory properties of the sausages were evaluated. Beef sausage had the lowest cooking yield and the highest hardness, while chicken sausage showed the opposite properties. The addition of oatmeal resulted in sausage products with less cooking loss and softer texture for all types of meat sausages. Such changes were more pronounced for beef low-fat sausage than for the other types of sausages. The results of moisture absorption suggested that the difference in cooking yield and hardness among sausage products was due to the water-retention properties of different meats and the substitute in response to heat treatment. Sensory evaluation indicated that the greatest overall acceptability of the sausage products were obtained from 10% oatmeal-added pork sausage and that the addition of oatmeal led to better acceptability for all types meat sausages.

The purpose of this study was to determine the organoleptic properties of mushroom pickles made at various compounding ratios according to central composite design for optimum organoleptic properties. In this study, various kinds of mushroom pickle were made at different compounding ratios of vinegar, sugar and salt-critical ingredients of the pickle recipe and the products were presented to an expert panel, who graded the subjects in 7 degrees for 5 items: color, flavor, hardness, taste and overall quality. As a result of sensory quality, mushroom pickles with 300g of vinegar, 150g of sugar and 60g of salt achieved the highest grade. Meanwhile, the results of Response Surface Methodology were different from the sensory quality results, showing that the optimum mixing conditions for overall organoleptic properties of mushroom pickle were 279.58g of vinegar, 179.34g of sugar and 59.09g of salt. (Ed- based on this conflict in results, I suggest that you make a final recommendation, of either the first, the second, or perhaps an intermediate, ratio)

This study was designed to investigate the possible utilization of mugwort as a source of functional ingredients. The approximate composition for mugwort powder was 5.06% moisture, 1.98% crude protein, 4.65% crude fat, 5.85% ash and 82.46% carbohydrate. The highest mineral content was potassium. The contents of total phenolic compounds and condensed tannin were 114 mg% and 11,000 mg%, respectively. The highest electron donating ability(EDA) was observed from the ethyl acetate and butanol fractions of mugwort powder but the lowest was shown by the hexane fraction. In color values, with increasing mugwort powder content, the 'lightness', 'redness' and 'yellowness' decreased in the crust, while in the crumb bread the 'lightness' decreased and the 'redness', and 'yellowness' increased. With the addition of mugwort powder as a substitute for strong flour over the range from 2.5% to 10.0%, the ratio of the volume and specific volume of white bread decreased while its weight increased. In the texture measurements for white breads, the hardness decreased slightly with the addition of 2.5% mugwort powder, but then increased with further additions of mugwort up to 10.0%. The addition of 2.5% mugwort powder increased the springiness and gumminess of white bread. The highest sensory scores for color, flavor, taste, texture and overall acceptance as evaluated by a student sensory panel were obtained from white bread with 2.5% mugwort powder and from the control. The highest sensory scores as evaluated by a baker sensory panel were obtained from white bread with 2.5% mugwort powder. In ranking test, overall acceptability of white bread was the highest in the control. Overall acceptance scores by sensory evaluation of white bread with 2.5% mugwort powder were not significantly different from those of control.
