The purpose of this study was to investigate the quality characteristics of tomato sauce, which is widely used in Western cuisine, according to tomato variety. The plum tomato sauce treatment had the highest pH at 4.13 while sauces made with Seo gwang and Young gwang tomatoes exhibited the lowest pH level of 4.07 (p<0.05). Sweetness was highest in the plum tomato sauce at $9.80^{\circ}$Brix. This might have been due to the fact that the plum tomato variety was the sweetest among the different tomatoes. There were no significant differences among the treatments in terms of reducing sugars, salinity, or viscosity. A color difference analysis indicated that redness (a-value) was highest in the plum tomato sauce, which contained a high level of lycopene. Sensory evaluations were performed by 15 professional panelists with scoring tests for color, flavor, taste, aftertaste, viscosity, and overall acceptability. The plum tomato sauce received the best scores in every evaluation, except for viscosity. These comparative results will support the development of better quality tomato sauce using plum tomatoes.

본 연구는 닭갈비 소스에 일반 토마토, 플럼 토마토, 캔 토마토를 첨가하여 닭갈비 소스의 품질과 관능적 특성을 높이려는데 그 목적이 있다. 닭갈비 소스에 토마토 종류별로 각각 0%, 10%, 20%, 30%, 40%를 첨가하여 시료로 준비하였다. 토마토 첨가량이 증가할수록 수분 함량, L, a, b값이 유의적(p<0.001)으로 증가하였고, 반면에 염도, 당도, 점도는 감소하였다. 특성차이검사 결과 토마토의 첨가량이 증가할수록 색의 강도, 매콤한 향, 입안에서의 느낌은 유의적인 차이를 보였다. 본 연구의 결과 닭갈비 소스에 토마토를 첨가할 때에 일반토마토의 경우 10~20%, 플롬 토마토와 캔 토마토의 경우 20%를 첨가하는 것이 가장 최적이라고 사료되었다. 이를 통하여 닭갈비 소스의 발전이 기대되어 진다.

To examine the effect of packaging method on strawberry, tomato, and plum quality, the rate of weight loss, Hunter a value, decay rate, anthocyanin contents, and microbial (total bacterial counts, mold and yeast, and pseudomonas) changes were determined during storage. Strawberry was packaged with low density polyethylene (LDPE). Tomato and plum were packaged with high density polyethylene film (HDPE). Strawberries, tomatoes, and plums were then stored at 4$^{\circ}C$ and 20$^{\circ}C$, respectively. LDPE package was the most effective on the decrease of decay rate of strawberry and the rate of weight loss for packaged strawberry was lower than that of the non-packaged. HDPE package was the most effective on the rate of weight loss during storage of tomatoes and plums regardless of storage temperature. Hunter a value increased during storage. Anthocyanin contents of plums increased overall with increasing storage time, and plums stored without package were changed more than those with package. Microbial changes of strawberry, tomato, and plum stored at 4$^{\circ}C$ and 20$^{\circ}C$ were monitored during storage. Packaging method did not affect the microbial change, yet temperature did affect the microbial change significantly. These results indicate that storage of these commodities at 4$^{\circ}C$ should be recommended in terms ,of microbial safety as well as quality and shelf-life.
