강황 분말의 첨가가 마요네즈의 품질특성, 항산화활성 및 산화안정성에 미치는 영향에 대해 평가하였다. 들기름으로 제조된 마요네즈에 강황 분말을 0.5%, 1%, 2%, 3% 농도로 첨가하여 4°C에서 12주 동안 저장하였으며, 강황 분말 무첨가구와 비교하였다. 강황 분말 첨가량이 많아짐에 따라 들기름 마요네즈의 L* (명도) 값은 유의적으로 감소하였고, a* (적색도)는 모든 실험구에서 negative (-)값이었으며, b* (황색도)값은 유의적으로 증가되는 경향이었다(p<0.05). 강황 분말 첨가량이 많아짐에 따라 총 페놀 함량 및 항산화 활성이 유의적으로 증가하였다(p<0.05). 마요네즈를 저장하는 동안 과산화물가는 유의적으로 증가하였으나, 강황 분말 첨가 시료에서는 유의적으로 낮았다(p<0.05). 마요네즈의 유화안정성은 저장 초기에 비해 저장 기간이 길어질수록 감소되는 경향이었으나, 0.5%의 강황 분말 첨가구는 무첨가구에 비해 유의적으로 높은 유화안정성을 보였으며, 1%의 강황 분말 첨가구는 무첨가구와 유의차를 보이지 않았다. 점도는 저장 기간이 경과됨에 따라 감소되었으나, 무첨가구에 비해 1% 이상의 강황 분말 첨가구에서 유의적으로 높았다. 들기름 마요네즈에 강황 분말 첨가 시 항산화 활성 증대 및 과산화물의 생성 억제에 효과적이었으며, 특히 0.5~1% 첨가시 마요네즈의 유화안정성 및 점도 개선에 도움이 될 것으로 판단된다.

The purpose of this study was to investigate the antioxidant activities, quality characteristics, and storage stability of perilla oil mayonnaise (PM) with different levels of onion powder (OP) from 0 to 3%. As the amount of OP increased, the L, a, and b values increased, but pH decreased (p<0.05). The addition of OP raised viscosity (p<0.05). The addition of OP to PM proportionally increased the total phenolic content, and antioxidant activities as measured by DPPH and ABTS radical scavenging activity, and FRAP assay. When compared to PM without OP, PM that contained OP had a peroxide value that was almost 1.94 times lower. The emulsion stability was between 97.62 to 94.92% in the PM without OP and PM with OP groups was 99.60% for 12 weeks. This study showed that the inclusion of OP in PM has the potential to inprove its quality, antioxidant activities, and storage stability.

This study aimed to investigate the changes in antioxidant activities, quality characteristics, and storage stability of mayonnaise prepared with perilla oil with the addition of mulberry powder ranging from 0 to 5%. The antioxidant activities of perilla oil mayonnaise (PM), as determined by DPPH and ABTS radical scavenging activity, as well as FRAP and total phenolics content were improved by the addition of mulberry powder compared with the control sample. Antioxidant activities were dependent on the amount of mulberry powder added. Lipid oxidation of PM decreased with a higher amount of mulberry powder, based on measurements of peroxide value. The emulsion stability of PM increased with decreases in the amount of mulberry powder level. The a-value in PM color increased with increasing amount of mulberry powder. Sensory evaluation showed that the highest score in overall acceptability of PM was achieved with 4% mulberry.
