Abstract

This study investigated the quality characteristics of apple jam added with ginger. The apple jam was prepared with apples, sugar, lemon juice and various amounts (0, 2, 4, 6, 8%) of ginger. Increasing the amount of ginger decreased moisture contents and sugar content of the jam, whereas the pH gradually increased. In addition, with increased amount of ginger, the lightness(L) and yellowness(b) significantly decreased, while redness(a) gradually decreased. There wasn't any significant difference in the samples with up to 4% ginger(p<0.05). In the texture profile analysis, hardness and adhesiveness increased significantly with increased amount of ginger. When more amount of ginger was added, cohesiveness increased with no significant difference based on the amount of ginger. With increased amount of ginger, springiness and chewiness gradually increased. The results of the sensory evaluation show that the apple jam added with 4% ginger got the highest overall-acceptability scores. In conclusion, it is possible to enhance the quality and acceptability of apple jam by adding 4% ginger.

이 연구는 생강을 사과잼에 첨가함으로서 생강의 최적 첨가량을 결정하고 생강 첨가 사과잼에 대한 기초자료를 제공하고자 하였다. 생강의 첨가량을 달리하여(0, 2, 4, 6, 8%) 사과잼을 제조한 후 품질특성으로 기계적 특성과 관능검사를 실시하였다. 생강의 첨가량을 달리하여 제조한 사과잼의 수분 함량과 당도는 생강의 첨가량이 증가함에 따라 유의적으로 감소하였다(p<0.05). pH는 생강의 첨가량이 많아질수록 증가하는 경향을 보였다. 색도에서 L값과 b값은 생강의 첨가량이 증가할수록 각 첨가군 간에 유의적 차이를 보이며 감소하였고(p<0.05), a값은 생강의 첨가량이 증가할수록 감소하였으며 4% 첨가군까지는 유의적 차이가 없었다. 텍스처 특성에서 경도(hardness)는 생강의 첨가량이 증가할수록 유의적 차이를 보이며 증가하였고, 부착성(adhesiveness)은 생강의 첨가량이 많아질수록 증가하였다. 응집성(cohesiveness)은 생강의 첨가량이 증가함에 따라 높아졌으며, 생강의 첨가량에 따른 유의적 차이가 없었다(p<0.05). 탄력성(springiness)과 씹힘성(chewiness)은 생강의 첨가량이 증가할수록 증가하는 경향을 보였다. 기호도 검사에서 전반적인 기호도(overall acceptability)는 생강 4% 첨가군이 가장 높은 것으로 나타났다. 위의 결과로부터 생강을 첨가하여 사과잼을 제조시 생강을 4% 정도의 수준에서 첨가한다면 사과잼의 기호도와 품질을 향상시킬 수 있을 것으로 기대된다.
