Korean journal of food and cookery science , volume 8, issue 3, 1992, Pages 233~239
The characteristics of Packsulgi were investigated with different cooking methods of conventional and pressure cookers and variation in panicle size of rice flour. The water contents of rice f1ours and Packsulgis were greater as the particle became coarser. The water contents of Packsulgis cooked with pressure cooker (P) were greater than those of conventional cooker (C). Degree of gelatinization in P was higher than that of C. There were no significant differences among the samples of P, whereas coarser f1ours tended to show higher degree of gelatinization than finer ones in C. The results of textural properties measured by rheometer showed that hardness, cohesiveness and gumminess of P was higher than that of C. The textural parameter of P increased as the particle became finer, whereas mat of C increased as the particle became coarser. L value of C was higher than that of P in me same particle size, whereas a and b value of P was higher than that of C. L and a value of both P and C increased as the particle became finer. b value in P increased as the particle became coarser, whereas mat in C increased as the particle became finer. According to me sensory evaluation, the appearance of C was more acceptable man that of P, whereas the texture of P was more acceptable than mat of C. There were no significant differences in overall quality among P and c and Packsulgis made by 60, 100 mesh rice f1our had higher acceptability than others.

Kim, Young-Sun ; Lee, Gui-Ju ;
Korean journal of food and cookery science , volume 8, issue 3, 1992, Pages 241~246
In this study. we measured the degree of browning of 3 potato culitivars harvested in Korea and compositions such as total phenols, tyrosine and polyphenol oxidase (PPO) activity. And we compared the extent of browning and composition factors to investigated which was related to the differences among 3 cultivars in browning. The results are as follows. 1. Among 3 culitivars, Sumi browned most after grinding and showed that browning in Sumi was preceded by significant1y shorter lag time. Namjak and Sumi were rapid to brown compared to Daejima. 2. Among 3 culitivars, Sumi contained significant1y more total phenols than did Namjak and Daejima. On the other hand, tyrosine contents by automatic analyzer of Sumi and Namjak were similar and mat of Daejima was the lowest. PPO activities were higher when catechol was used as substrate and Sumi contained more PPO than did the other culitivars. 3. When we compared me browning behavior and composition of 3 culitivars, significant correlation was obtained between browning extent and total phenols, tyrosine and PPO. For me individual cultivar, Sumi which browned much extensively showed higher correlation between browning and PPO. On the other hand, the other cultivars showed higher correlation with total phenols and tyrosine, respectively.

Choi, In-Ja ; Kim, Young-A ;
Korean journal of food and cookery science , volume 8, issue 3, 1992, Pages 281~289
The physicochemical, rheological and sensory characteristics of Backsulgies added with dietary fibers-cellulose, pectin and wheat bran-were investigated. The maximum acceptable ratio of fibers was 10% for wheat bran or cellulose, 3% for pectin. As me results of physicochemical analysis, cellulose and pectin had larger water-binding capacity man wheat bran. Swelling power was increased with temperature increment. But the type of added dietary fiber did not make significant differences. The degree of gelatinization was measured by maltose content. The retrogradation of backsulgies was significantly delayed by the addition of dietary fibers. The retardation effect of dietary fibers for retrogradation of backsulgies was also proved by textural analysis and time constant determination of Avrami equation. Pectin had especially excellent delaying effect while me storage time extended. There were no significant differences in sensory characteristics between me backsulgi with no dietary fibers and backsulgies added with cellulose 3%, pectin 1% and wheat bran 3%. Therefore, we concluded mat cellulose 3%, pectin 1% and wheat bran 3% were me optimum addition ratios, which have the delaying effect of retrogradation, and which could be accepted as same as conventional backsulgies organoreptically.

Choi, Young-Seon ; Kim, Young-A ;
Korean journal of food and cookery science , volume 8, issue 3, 1992, Pages 333~341
The physicochemical, rheological and sensory characteristics of 'BACKSULGIES', which was added with potato peel, guar gum or polydextrose, were investigated. The maximum acceptable addition ratio of dietary fiber to 'BACKSULGI' was 10%. And optimal addition ratio was 3% for all samples. The water binding capacity was affected by dietary fiber sources and incubation conditions (temperature and time). The Guar gum had me highest value of water binding capacity. The solubility was highly related with water binding capacity and me swelling power was increased with temperature increment. The degree of gelatinization was not significantly different with dietary fiber sources. But me values of gelatinization of 'BACKSULGIES' added with dietary fibers were significantly higher than mose of 'BACKSULGI' with no dietary fiber. Generally hardness and brittleness incresed along with storage time. But me hardness of 'BACKSULGIES' added with dietary fibers was significantly lower man those of 'BACKSULGI' with no dietary fiber. The retardation effect of dietary fibers for retrogradation of 'BACKSULGIES' was also proved by time constant determination of Avrami equation. Sernsory evaluation revealed that me addition of dietary fibers did not reduce the organoreptic quality. Therefore potato peel 3%, guar gum 3%, polydextrose 3% were optimum addition ratio which could be accepted as conventional 'BACKSULGI'. As me results of this study, it was proved mat the additions of dietary fibers to 'BACKSULGI' had the retardation effect of retrogradation.
