  • Backsulgies containing various levels of guar gum(0g, 2.5g or 5g) were ingested by ten healthy male subjects after 12-h fast. Guar backsulgies was given a time in a week a time in a week for 3 weeks with 75g glucose. The Sensory qualities of backsulgies containing guar gum powder of different levels(0g, 2.5, 5g) were also evaluated using a hedonic scoring technique. On each test day 4ml samples of venous blood were taken from the fasted subjects. Further 4ml post-prandial blood samples were taken from the subjects 30, 60, 90 and 120min after guar backsulgies had commenced. Result were as follows: Plasma glucose and insulin levels were not sifnificantly reduced according to guar gum levels in backsulgies. But plasma glucose and insulin levels of the case which ingested 5g guar backsulgies tended to be lower than those of the case which ingested 0g or 2.5g guar backsulgies. Therefore it is recommended that 5g guar backsulgies is most effective snack of diabetics. KEY WORDS: guar backsulgies plasma glucose, plasma insulin, snack.

  • 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.

  • 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.

  • The effects of addition of brown rice flour on the Backsulgies were examined. We chose the addition ratio of brown rice flour as 0%, 50%, 100% along with the pilot study. The addition of brown rice flour did not make significant changes in water-binding capacity, swelling power and the degree of gelatinization. But the addition of brown rice flour had a delaying effect of retrogradation of Backsulgies by textural analysis. In sensory evaluation, the Backsulgi added brown rice flour 50% had the highest value in the overall quality of sensory characteristics. But there was no significant difference in the other sensory characteristics between the 50% and 0% added with. Therefore we concluded that the addition of brown rice flour on Backsulgies improve the sensory characteristics as well as delay the retrogradation and would be a good source of dietary fiber.

  • This study was conducted to evaluate the quality characteristics of Backsulgies prepared using different ratios (0, 10, 20, 30, 40%) of trehalose after 4 days of storage. As the concentration of trehalose increased, the moisture content of the Backsulgies decreased. Furthermore, increased levels of trehalose, resulted in significantly lower L and b values. However, the a values did not differ significantly in response to the addition of trehalose. The total cell counts of Backsulgies also decreased as the level of trehalose increased, which indicates that microorganisms were inhibited by its addition. Furthermore, the hardness of the Backsulgies decreased as the level of trehalose increased, whereas the hardness of the Backsulgies increased as the storage time was extended. Finally, the sensory evaluations revealed that the chewiness and hardness of Backsulgies decreased as the level of trehalose increased.

  • Four different oligosaccharides used to determine their effects on gelatinization and retrogradation of Backsulgies(BSG), Korean traditional rice cake, were cyclodextrin, isomaltooligosaccharide, fructooligosaccharide and maltotetrose, with 3 or 6%(w/w), based on the rice flour. From the Amylograph and blue value data, adding 6% cyclodextrin into the rice flour fastened the gelatinzation process, and delayed the retrogradation in stored BSG at 4$\^{C}$ for up to 3 days, probably due to its cyclic structure. Using rheometer, the hardness of freshly made BSG added with cyclodextrin was significantly lower than that of control BSG, and increased with storage time in all BSGs at refrigerated temperature. When using maltotetrose in rice flour, the hardness of BSG was also significantly low, but slightly higher than that of cyclodextrin. Hunter “L” value in BSG decreased with the addition of oligosaccharides, but the higher the level of oligosaccharide in BSG, the insignificant the Hunter “a”,“b” values of BSG. From the X-ray diffraction studies, the rice flour showed typical A pattern, and the crystallinities of all BSG gave amorphous V type. The highest peaks of X-ray patterns in BSG added with 6% cyclodextrin or maltotetrose were, however, lower than that of the control, meaning the less crystalline, retrograded starch in the former BSGs. Based on sensory evaluation, BSG added with all oligosacchrides were not significantly different in taste, flavor, chewiness, moistness and overall preferences, with slightly darker color with longer storage time, compared to the control BSG.

  • The purpose of this study was to select an ingredient acting as a natural emulsifier to retard the retrogradation of rice cake by the measurement of mechanical characteristics of the cakes. For the purpose, Backsulgi, the most basic type of rice cake, was prepared by adding various ingredients having high contents of lecithin such as raw soybean powder, parched soybean powder, soybean oil, egg yolk powder, and the measurements and observations on the chromaticity, swelling power, pore ratio and cross-section were made. In addition, changes in the textural characteristics of Backsulgi samples were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2 and 3 days. The results of the study were as follows: 1. In terms of chromaticity, the Backsulgi samples added with egg yolk powder, raw soybean flour and parched soybean flour were higher in yellowness(b) than the controls. 2. Both swelling power and pore ratio of Backsulgies added with raw soybean flour were higher than those of controls. 3. A cross-sectional observation using an electron microscope indicated that rice flour particles of controls had uneven pores and were conglomerated in a large lump while Backsulgi samples of raw soybean flour or roasted soybean flour had large and even pores and showed loosened bonding to be transformed into a sponge shape. 4. In hardness, Backsulgi samples added with raw soybean flour had less changes in hardness than that of controls, indicating that the effect of retarding retrogradation was higher when the storage time got longer.
