토마토 품종 및 부위별과 토마토 가공제품의 ascorbic acid, lycopene, ${\beta}$-carotene과 ${\alpha}$-carotene 함량 비교 = Comparison of Ascorbic Acid, Lycopene, ${\beta}$-carotene and ${\alpha}$-carotene Contents in Processed Tomato Products, Tomato Cultivar and Part

다국어 초록 (Multilingual Abstract)

For tomatoes containing valuable nutrients and biological active substances, this study examined differences in the ascorbic acid, lycopene, ${\beta}$-carotene, and ${\alpha}$-carotene contents in processed tomato products according to tomato cultivar and the part of fully ripened tomatoes. According to the results, the ascorbic acid content was different among tomato cultivars, and it was far higher in jelly than in pulp among the parts of tomatoes. The ascorbic acid content in processed tomato products was higher in tomato juice than in other types of tomato products, but the difference was mainly from various additives used in addition to tomatoes; therefore, it was somewhat unreasonable to compare the ascorbic acid content among the products. It was found that the lycopene content was not significantly different between pulp and jelly in each cultivar. In most of the cultivars, the ${\beta}$-carotene content was not significantly different according to the parts, but in cultivar yeoyong, the content was 2.7 times higher in jelly than in pulp. The ${\alpha}$-carotene content was highest in both pulp and jelly for all the cultivar, and the lycopene and ${\beta}$-carotene contents were lowest regardless of parts for cultivar Yellow Carol. ${\alpha}$ carotene was not detected in either pulp or jelly. The lycopene, ${\beta}$-carotene, and ${\alpha}$-carotene contents showed significant difference among processed tomato products, and the difference came mainly from the type of processing and additives. Tomatoes have superior characteristics, but they are usually consumed uncooked in Korea. Thus, this study aimed to contribute to the various forms of consumption of tomatoes, that is, the development of various nutritionally excellent cooking methods using processed tomato products.
