Preservation stability of the extract from dried green tea produced in Jeju, extracted at
for 15 min and bottled in PET container after filtration and then settled at
, indoor at room temperature and outdoor, respectively, was estimated. Color L-value was almost constant but color of the extract became darkened during storage, especially in indoor storage. Main catechins of green tea extract were (-)-epigallocatechin, (-)-epigallocatechin gallate, epicatechin, (+)-catechin, epicatechin gallate in order, and the content of epigallocatechin was 53.8%. Nevertheless total catechin content was not changed in cold storage, and
of total catechins were reduced in outdoor or indoor storage after 14 weeks. Caffeine content were increased but total polyphenols were not changed largely during storage. Election donating abilities (EDA) showed more than 60% without influence of storage conditions and periods. Nitrite scavenging abilities (NSA) showed more than 90% at pH 1.2, but those were decreased gradually as pH increased, and then disappeared at pH 6.0. Color, polyphenols, antioxidant activities of extract were not so changed for more than 3 months. Microbial growth was not shown during same periods, due to heat treatment of the extracts at
for 10 min.

Korean Journal of Food Preservation, volume 13, issue 4, 2006, Pages 450~456
The favorable effect of ascorbic acid and cysteine on the improvement of rice bread quality was investigated by creating and comparing 6 experimental rice breads(RB-1 to RB-6). The RB-3 showed a relatively higher loaf volume, specific loaf volume and bread yield than the other breads. Crust and crumb color of breads were measured using a Hunter celery meter. The RB 5 and RB 6 showed the higher cut L-value than the other broads. As the proportion of the rice in the experimental breads increased, both the crust L-value and the crumb L-value showed higher values. According to the texture profile analysis, the hardness of the RB-1 to RB-3 were lower than those of the other breads. The springness of the experimental broads increased as the percentage of the rice in the breads increases. However, less proportions of rice to breads provided significantly lower level of the chewiness. The cohesiveness did not show any specific pattern by the proportion of rice to breads. The degree of retrogradation of the breads was accelerated when the breads contained more rice or when the breads had neither ascorbic acid nor cysteine. Therefore, RB 3, which contained ascorbic acid and cysteine and less rice, showed the highest retardation in the degree of retrogradation. In addition, the RB 3 showed the highest overall acceptance scores by sensory evaluation.
