The effects of replacement of sucrose with isomaltooligosaccharide(IMO) on physical, sensory and textural characteristics of high-ratio cakes were investigated. As IMO level increased, the specific gravity of batter decreased and the moisture content of crumb increased. A higher degree of IMO replacement for sucrose made cakes softer and more moist. The 40% and 60% IMO replcement cakes showed good acceptability. The hardness, chewiness and gumminess measured by texture analyzer were decreased with increasing IMO level.

This study was conducted to determine the quality characteristics of grape jellies for the elderly. The jellies contained sugar (control) or sugar derivative sweeteners (erythritol, isomaltooligosaccharide, sorbitol, and xylitol). Agar (0.31%) and $\kappa$-carrageenan (0.27%) were the gelling agents. The average age of the subjects participating in the acceptance test was 79. The lightness (L), redness (a), and yellowness (b) values of the agar gel with erythritol mostly decreased, indicating a darker and pale red color. The L and b values of the carrageenan gel with sugar derivative sweeteners increased, indicating brighter and yellowish color. The agar and carrageenan gels with sorbitol showed higher gelling and melting temperature, indicating that gelation occurred easily and did not easily melt. The agar and carrageenan gels with xylitol showed a low-melting temperature, indicating low stability with temperature change. The break-down rate of the agar and carrageenan gels with erythritol was low, whereas that of agar gel with sorbitol was relatively high despite its high melting temperature. Hardness, cohesiveness, gumminess, and chewiness of the gels with sugar derivative sweeteners decreased, and this tendency was most distinct with isomaltooligosaccharide in the agar gel and with sorbitol in the carrageenan gel. The rupture properties of the gel were the same as the hardness of the gel. Sensory acceptance of the agar gels with erythritol, sorbitol, isomaltooligosaccharide, and the carrageenan gel with erythritol was fairly high, whereas that of the agar gel with xylitol and the carrageenan gel with isomaltooligosaccharide and xylitol was low. The results show that sorbitol and erythritol are appropriate as sugar substitutes in grape jellies for the elderly about the acceptability and stability of the gels.

설탕의 40%를 프락토올리고당이나 이소말토올리고당으로 대치하여 구운 스폰지 케이크를 2주간 섭취하게 하여 여대생의 변비개선에 대한 효과를 살펴보았다. 두 올리고당 모두 섭취 후 배변 횟수와 변의 경도를 유의적으로 개선시켰다. 프락토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 배변시간이 섭취 1주 후부터 유의적으로 감소하였으며, 이소말토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 변의 모양, 변색, 배변 시 노력과 배변 후 상쾌함 등이 섭취 전보다 섭취 후에 유의적으로 개선되었다. 섭취 중에 나타난 소화장애 현상으로는 설사, 복통, 메스꺼움, 더부룩함, 방귀, 식욕 감소, 체중감소, 복부 팽만감 등이 나타났고, 프락토올리고당을 첨가한 스폰지 케이크 섭취 군에서는 이들 장애현상 중 복부 팽만감이나, 방귀, 메스꺼움 현상이 섭취 후 1~2시간 안에 나타나기 시작하여, 실험 기간 내내 지속되었다. 반면 이소말토올리고당을 첨가한 스폰지 케이크를 섭취한 군에서는 2~3일 정도 소화장애 현상이 나타났으나, 그 후에는 섭취 후에 장애 현상이 없어졌다. 섭취종료 일주일 후에는 프락토올리고당에 의한 소화장애 현상은 곧 사라졌으나, 대부분의 피검자들은 섭취 전에 나타난 변비현상이 다시 나타났다. 배변상황의 개선여부와 소화장애 현상을 종합적으로 판단하였을 때, 두 올리고당 모두 인체의 장기능 개선에는 효과가 있었으나, 비교적 안전성이 좋은 이소말토올리고당을 첨가한 스폰지 케이크 섭취가 변비 치료에는 더 긍정적으로 나타났다.

To increase the utilization of citron(Citrus junos), manufacturing conditions of citron jelly were studied. Citron extract was diluted 7 fold for jelly processing and it's pH was 2.64. Due to the low pH of citron extract, 2.5∼3.0% of pectin was added which was slightly higher than the amount for ordinary jelly process. To reduce the loss of citron flavor and vitamin C, it was heated for 10 min. and found to be enough for proper hardness of jelly. Agar and gelatin was used as jellying agents to improve the physical properties of pectin jelly. From the result of compression curve analysis, addition of 5% and 7% of gelatin were more effective in jelly texture than agar in 1.5% and 2.5% pectin jelly, respectively. Sucrose was replaced by glucose and oligosaccharide; galactooligosaccharide, fructooligosaccharide and isomaltooligosaccharide. From the sensory evaluation analysis, 30% of sucrose and 30% of isomaltooligosaccharide in jelly was evaluated as superior to other sugars.

Effects of oligosaccharides substituted for sucrose on the sponge cake quality were investigated. Fructooligosaccharide and isomaltooligosaccharide were used as oligosaccharides. Oligosaccharides decreased batter specific gravity, and increased cake specific volume and expansion ratio, showing that oligosaccharides had higher foaming ability and foam stability than sucrose. Oligosaccharides darkened the crust and crumb color of cakes. Addition of oligosaccharides made cakes darker, softer, more moist and more acceptable as perceived by panels. The acceptability was significantly correlated with crust and crumb color, softness, moistness and flavor(p<0.01). The textural characteristics including hardness, chewiness and gumminess of cakes were decreased by replacing sucrose with oligosaccharides. The hardness, gumminess and chewiness among sensory characteristics were negatively correlated with acceptability(p<0.05). Therefore, oligosaccharides should be a good alternative for sucrose in cake making because the sponge cake quality was greatly improved by partial repacement of sucrose with oligosaccharides.

There are increasing evidences that prebiotics can modulate various properties of the immune system. This study was conducted to investigate effects of three kinds of fructans (chicory inulin, chicory inulin oligosaccharide and fructooligosaccharide) and a glucose oligomer(isomaltooligosaccharide) in large bowel mass and innnunoglobulin A (IgA) in rats. Forty five Sprague-Dawley male rats weighing about 1909 were randomly sorted to receive one of the five treatments, which were control diet, control diet+6% isomaltooligosaccharide (IMOS), control diet+6% fructooligosaccharide (FOS), control diet+6% chicory inulin oligosaccharide (CIOS), or control diet + 6% chicory inulin (CI). Rats were pair-fed and received the experimental diets for 5 weeks. Cecal and colonic wall weights were significantly higher in fructan (FOS, CIOS, CI)-fed groups compared with control and IMOS groups, and the length of colon was elevated in FOS and CIOS groups compared with control group. Fecal concentrations of acetic acid and total short-chain fatty acids (SCFAs) were significantly elevated in fructan-fed groups. Plasma and cecal levels and fecal excretion of immunogiobulin A (IgA) in rats were not significantly different among groups. However, fructooligosaccharide tended to increase IgA level in cecum. Cecal IgA level was significantly negatively correlated with pH of cecal content (r=-0.337), positively correlated with acetic acid level (r=0.310). Fecal IgA excretion was positively correlated with total SCFA (r=0.311) and propionic acid (r=0.400) level in feces. These results indicate that fructooligosaccharide and chicory inulin oligosaccharide exerted trophic effects in large bowel wall, increased production of SCFAs and decreased pH, which were conditions positively associated with cecal and colonic IgA secretion.

Isomaltooligosaccharide (IMO) is a promising dietary component with prebiotic effect, and the long-chain IMOs are preferred to short chain ones owing to the longer persistence in the colon. To establish the optimal process for synthesis of long-chain IMOs, we systematically examined the reaction condition of dextransucrase of Leuconostoc mesenteroides B-512F by changing the ratio of sucrose to maltose (varying as 1:4, 1:2, 1:1, and 2:1) and amount of each sugar (from 2% to 20%). As a result, a ratio of 2:1 (sucrose to maltose, 10:5% or 20:10%, w/v) was determined as an optimal condition for long-chain IMO synthesis (DP3-DP9) with relatively higher yields (70-90%, respectively).

This study was carried out to investigate the effects of oligosaccharide addition on Jeung-Pyun fermentation. Fructooligosaccharide (FOS), isomaltooligosaccharide (IMOS), galactooligosaccharide (GOS) were used at the concentration of 15%, 25% or 35% of the rice in Jeung-Pyun ingredients. The physicochemical properties, sensory evaluation and instrumental characteristics were examined. The internal structure of Jeung-Pyun samples was observed by SEM. The pH of Jeung-Pyun batters was decreased as the fermentation progressed. Compared with the control using sucrose, the specific volume of Jeung-Pyun was higher in the 15% and 25% of oligosaccharide-added samples. The degree of gelatinization decreased more slowly than control as the storage time increased both at 20$\^{C}$ and 4$\^{C}$. In sensory evaluation, Jeung-Pyun with FOS and IMOS at the levels of 25∼35% and GOS at the levels of 25% showed the best scores. In instrumental characteristics, springiness, gumminess, hardness and cohesiveness were similar among all samples during storage at 20$\^{C}$ and 4$\^{C}$. In the internal structure of Jeung-Pyun observed by SEM, Jeung-Pyun substituted with oligosaccharide at the levels of 25% for sucrose showed large and regularly distributed air pores. In conclusion, the replacement of sucrose with oligosaccharide in Jeung-Pyun ingredients appeared acceptable in terms of fermentative aspects.

The aim of this study was to evaluate the effects of oligosaccharides(fructo or isomalto ) contained in sponge cake on blood lipids and intestinal physiology in rats. The experimental diet was mixed with 30% sponge cakes. Normal male Sprague Dawley rats weighing about 530g were randomly assigned to three groups and placed experimental diets and deionized water at free access for 25 days. Rat in control group received a diet mixed with sponge cake containing sucrose only at 21.58g/100g diet and rats in the other two groups received diets mixed with sponge cakes of which 40% sucrose was replaced with each oligosaccharide. The results obtained were as follows: No significant differences in efficiency of food, liver weight and intestinal length were observed among groups. The cecal contents and cecal wall weights were increased more in fructooligosaccharide(FO) group than control. The pH of cecal contents decreased significantly in two oligosaccharide groups. The water contents of fresh feces in FO group were the highest and the those of two oligosaccharide groups were higher than that of control. Dry fecal weight increased significantly in isomaltooligosaccharide(IMO) group. Total serum cholesterol concentration was significantly lower in FO group. Serum triglyceride(TG) was not significantly different among three groups at p<0.05, but serum TG of FO group was lower than those of other groups. In conclusion, 40% replacement of sucrose with oligosaccharides in sponge cake may have beneficial effects on lipid metabolism and intestinal function in rats.
