This study investigated the quality characteristics and antioxidant activities of salad dressing prepared with Jerusalem artichoke powder (0%, 4%, 8%, and 12%). The pH, soluble solid content, and viscosity increased as the content of Jerusalem artichoke powder increased. The titratable acidity showed no significant differences between samples. The lightness values decreased, while the redness and yellowness values increased with increasing amounts of Jerusalem artichoke powder. The total polyphenol content ranged from 52.00-69.64 μg GAE/g, and increased with the increase in Jerusalem artichoke powder levels. The antioxidant activities measured via DPPH and ABTS radical scavenging activity and reducing power also increased with increasing Jerusalem artichoke powder, at a higher rate than in the control. These results suggest that it is beneficial to add Jerusalem artichoke powder when in salad dressing.

Recently, health concerns related to NaCl overconsumption have led to an increased demand for sodium-reduced foods. The purpose of this research is to investigate the possibility of using enzymatically hydrolyzed isolated soybean protein (eHISP) to reduce the level of salt in salad dressing. The intensity of the salty taste enhancing effect was 31%, 29%, 43%, and 52% in the samples with 0.1%, 0.5%, 1.0%, and 1.5% eHISP added, respectively. There are significant differences between the control and samples (p<0.05). The overall acceptability was increased as the amount of added eHISP was increased when eHISP was 1.0%. However, it was lower when 1.5% eHISP was added. The pH of salad dressing was increased as the eHISP addition was increased. The results showed that the addition of eHISP to a salad dressing significantly enhances its salty taste effect.

This study was conducted to develop a salad dressing using Prunella vulgaris L. (PV) extracts. In addition, the study was also aimed at evaluating the quality characteristics of the salad dressing containing various amounts of PV extracts. Salad dressing was prepared by adding 0% (PD-0), 9.4% (PD-20), 18.8% (PD-40), 28.2% (PD-60), 37.6% (PD-80), 47.0% (PD-100) of PV extract. The quality characteristics (sugar contents, salinity, color value, total phenol contents, total flavonoid contents, DPPH, ABTS+ radical scavenging activities, and sensory acceptability) of the dressing were analyzed. According to the results of the study, the sugar contents and salinity of salad dressing increased according to the added amount of PV extract (p<0.001). The color values of lightness and yellowness of salad dressing increased according to the added amount of PV extract, whereas color value of redness decreased (p<0.001). Antioxidant activities were improved depending on the amount of PV extracts (p<0.001). The sensory acceptability (flavor, medicinal flavor, saltiness, sourness, bitterness and viscosity) were significantly higher in the dressing added with 18.8% PV extracts than in the other samples. Based on this result, a storage experiment was conducted by comparing PD-40 and PD-C. After 4 weeks of storage at 4℃ and 24℃, the quality characteristics were observed and the pH was increased in the later stages of storage (p<0.05). The depicted that, viscosity increased with storage time at 4℃ (p<0.001). General bacteria and coliform were not detected during storage. These results indicated that salad dressing with the addition of 18.8% PV extracts has the best quality.

This study was conducted to evaluate the quality characteristics and antioxidant activities of salad dressing prepared with acaiberry powder (0, 1, 3, and 5%). The pH and titratable acidity increased as the acaiberry powder increased. The sugar content showed no significant differences between samples. The viscosity was lowest in the controls and increased with increasing amounts of the acaiberry powder. The lightness and yellowness values decreased, while the redness values increased with increasing amounts of acaiberry powder. The total polyphenol content ranged from 10.26-45.19 mg GAE/100 g, increasing with increased acaiberry powder levels. The antioxidant activities measured via DPPH radical scavenging activity, reducing power and FRAP also increased with increasing acaiberry powder concentrations. Finally, a consumer acceptance test revealed that up to 3% acaiberry powder could be added to salad dressing to provide high antioxidant activity without sacrificing sensory quality.

The purpose of this study was to investigate the possibility of the use of enzymatically hydrolyzed anchovy protein (eHAP) to enhance the salty taste in salad dressing when it was applied in cooking. The intensity of the salty taste was enhanced by 5-11% when 0.1-1.5% eHAP was added. This indicates that the salty taste enhancing effect was decreased as the amount of added eHAP was increased. However, there are no significant differences between the control and samples (p>0.05). The overall preference was increased as the amount of added eHAP was increased. The preference value was the highest when 1.0% of eHAP was added, while it was slightly lower when 1.5% of eHAP was added. This may be because the content of free amino acids with a bitter taste contained in eHAP was increased. The pH value was increased as the amount of added eHAP was increased. With respect to the chromaticity, the lightness and yellowness were increased but the redness was not significantly changed when the amount of added eHAP was increased. It was found that the addition of eHAP to a salad dressing enhanced the salty taste and the preference, but the enhancement was not significant.

본 연구에서는 양조간장만을 사용하여 음식 내에 소금을 대체하고 나트륨의 사용량을 줄여 섭취를 줄일 수 있는지 를 알아보기 위하여 샐러드 드레싱에 소금과 양조간장의 사용량을 달리하여 전반적인 맛과 짠맛의 차이를 비교하고 나트륨 분석을 통해 정량적인 나트륨 감소량에 대해 살펴 보았다. 소금을 사용하였을 경우 가장 선호하는 샐러드 드레싱의 나트륨 함량은 3.85±0.03 g/L이었으며, 양조간장 을 사용하였을 경우에는 0.68±0.02 g/L이었고, 0.53±0.01- 0.68±0.02 g/L의 농도에서는 소금을 사용하였을 때와 전반 적인 맛에 있어서 유의적인 차이를 보이지 않았다(p<0.05). 짠맛의 차이에 대한 평가에 있어서 소금을 사용하였 때와 가장 비슷한 짠맛을 나타낸 실험구의 나트륨의 농도는 0.53±0.01 g/L로 나타났으며, 짠맛 차이에 있어서도 전반적 인 맛의 차이에서와 같은 범위의 나트륨 농도에서 유의적 인 차이를 보이지 않았다(p<0.05). 소금을 대신하여 양조간 장만을 사용할 경우 전반적인 맛에 있어서는 약 82.4%, 짠맛에 있어서는 86.2%의 나트륨 함량을 줄일 수 있었다. 이러한 결과는 양조간장 내에는 짠 맛을 증진하는 것으로 알려진 단백질, 펩타이드, 유기산 및 간장 고유의 향 이외 에도 짠맛을 증진시킬 수 있는 새로운 물질이 존재할 수 있을 것으로 판단된다.

In this study, the quality characteristics and antioxidant activity of mulberry salad dressing prepared with yam juice during storage at 5℃ for four weeks were evaluated. The salad dressing was prepared with a salad base, mulberry, omija, and yam (4:4:6:1 or 4:4:6:3). Fresh yam juice was added to the salad dressing at 0, 7, and 18% levels. After four weeks storage, the pH increased whereas the acidity decreased. As the yam concentration increased, the pH increased to 3.84 and the acidity decreased to 0.14%. The Hunter color L (lightness), b (yellowness), and a (redness) values decreased over the storage period. After four weeks storage, the viscosity increased from 83.2 to 158.5 cp according to the amount of yam juice that was added. The antioxidant activity, such as the DPPH radical scavenging activity, and the total polyphenol content of the salad dressing improved as the yam concentration increased. Moreover, according to the storage time, the peroxide value did not increase. These results show that the mulberry salad dressing to which omija and fresh yam juice were added maintained its freshness with high antioxidative activity during storage.
