In a previous study, baekseolgi with xylitol or sucralose was comparable to baekseolgi with sugar in terms of all sensory characteristics. However, the hardness of sucralose baekseolgi increased considerably during storage while that of xylitol baekseolgi remained unchanged. To improve the physical limitations observed in sucralose baekseolgi, a combination of sucralose and xylitol were substituted for sugar when preparing baekseolgi (SL0~SL100, SLn; baekseolgi where sugar was replaced with n% sucralose and 100-n% xylitol based on relative sweetness to sugar). All SLn baekseolgi samples were not significantly different from sugar baekseolgi in terms of sensory properties. The moisture content was not different between sugar and xylitol baekseolgi (SL0), but decreased significantly as the amount of sucralose increased (P<0.01), which correlated with cohesiveness of baekseolgi. Texture profile analysis revealed that hardness of SLn baekseolgi increased without any noticeable change in moisture content after storage at $4^{\circ}C$ for 7 days. In addition, the hardness after storage was the highest in sucralose baekseolgi (SL100), which was comparatively lower in SL0~SL80 containing xylitol presumably due to the hygroscopic characteristics of xylitol. In particular, SL20 was found to be comparable to sugar baekseolgi in terms of moisture and cohesiveness during storage. The results showed that the combination of xylitol and sucralose could be a potential sugar substitute in terms of not only sensory characteristics but also physicochemical properties.

The objective of this study was to investigate the physicochemical characteristics and sensory evaluation of dacquoise made with sugar or sugar replacement (tagatose, erythritol). Sugar (S) was replaced with tagatose (T), and sugar powder was replaced with tagatose (TS), and erythritol (TE). S showed the highest sugar contents compared with TS and TE (p <0.05) but there were no significant differences with T. There were not significant differences in specific gravity and spread factor among the sweeteners. S and T tended to have higher loss factors than TS & TE. The more tagatose was increased, the more the redness value increased compared with S, and sucrose showed similar tendency for lightness (redness; TS > T > TE > S, lightness; S > T > TS > TE). TE showed good results for physical characteristics whereas T was better in the sensory test. The above results bear out that tagatose and erythritol both are suitable as alternative sweeteners for making dacquoise, but tagatose was better. Tagatose appeared to be a better replacement for sucrose in baking dacquoise, and dacquoise with 33% of the sugar replaced tagatose (T) could be suitable for use by diabetic and obese people. 95.1% tagatose (TS) maybe appropriate for diabetic patients. In conclusion, tagatose is a suitable sugar replacement for making dacquoise.

The effects of sugar substances (oligosaccharide, xylitol and erythritol) as alternative ingredients to sucrose on the quality characteristics and antioxidant activities of aronia jam were evaluated. The different types of sweeteners did not influence the pH, total acidity and sugar contents of the jam. The sucrose-containing jam showed the highest spreadness, while the oligosaccharide and erythritol-containing jams showed lower spreadness. In the chromaticity determination, the sucrose-containing jam showed the lowest L, a and b values compared with the other sweetener groups. There were no significant differences in the total polyphenols, flavonoids and anthocyanin contents in the jams. The antioxidant activity indicated by the DPPH and ABTS radical scavenging activities was over 70%. Sensory evaluation indicated the xylitol-containing jam to have the best preference in taste, flavor and overall acceptance. These results suggested that xylitol may be a good sugar substance in aronia jam.

Stevia (Stevia rebaudiana Bertoni) is a perennial herb widely distributed in the mountainous area of Paraguay. It belongs to the family Compositae and contains 6 to 12 percent stevioside in the leaves. Stevioside is a glucoside having similar sweetening character to surgar and the degree of sweetness is approximately 300 times of sugar. Since Korea does not produce any sugar crops, and the synthetic sweetenings are potentially hazardous for health, it is rather urgent to develop an economical new sweetener. Consequently, the current experiments are conducted to establish cultural practices of stevia, a new sweetening herbs, introduced into Korea in 1973 and the results are summarized as followings: 1. Days from transplanting of cuttings to the flower bud formation of 6 stevia lines were similar among daylengths of 8, 10 and 12 hours, but it was much greater at daylengths of 14 or 24 hour and varietal differences were noticable. All lines were photosensitive, but a line, 77013, was the most sensitive and 77067 and Suweon 2 were less sensitive to daylength. 2. Critical daylength of all lines seemed to be approximately 12 hours. Growth of plants was severely retarded at daylengths less than 12 hours. 3. Cutting were responded to short daylength before rooting. Number of days from transplanting to flower bud formation of 40-day old cuttings in the nursery bed was 20 days and it was delayed as duration of nursery were shorter. 4. Number of days from emergence to flower bud formation was shortest at short day treatment from 20 days after emergence. It was became longer as initiation of short day treatment was earlier or later than 20 days. 5. Plant height, number of branches, and top dry weight of stevia were reduced as cutting date was delayed from March 20 to May 20. The highest yield of dry leaf was obtained at nursery duration of 40-50 days in march 20 cutting, 30-40 days in April 20 cutting, and 30 days in May 20 cutting. 6. An asymptotic relationship was observed between plant population and leaf dry weight. Yield of dry leaf increased rapidly as plant population increased from 5,000 to 10,000 plants/10a with a reduced increasing rate from 10,000 to 20,000 plants/l0a, and levelled off at the plant population higher than 20,000 plants/l0a. 7. Stevia was adaptable in Suweon, Chengju, Mokpo and Jeju and drought was one of the main factors reducing yield of dry leaf. Yield of dry leaf was reduced significantly (approximately 30%) at June 20 transplanting compared to optimum transplanting. 8. Yield of dry leaf was higher in a vinyl house compared to unprotected control at long daylength or natural daylength except at short day treatment at March 20. Higher temperature ill a vinyl house does not have benefital effects at April 20 transplanting. 9. The highest content of stevioside was noted at the upper leaves of the plant but the lowest was measured at the plant parts of 20cm above ground. Leaf dry weight and stevioside yield was mainly contributed by the plant parts of 60 to 120cm above ground but the varietal differences were also significant. 10. Delayed harvest by the time of flower bud formation increased leaf dry weight remarkably. However, there were insignificant changes of yield as harvests were made at any time after flower bud formation. Content of stevioside was highest at the time of flower bud formation and earlier or later harvest than this time was low in its content. The optimum harvesting time determined by leaf dry weight and stevioside content was the periods from flower bud formation to right before flowering that would be the period from September 10 to September 15 in Suweon area. 11. Stevioside and rebaudioside content in the leaves of Stevia varieties were ranged from 5.4% to 14.3% and 1.5% to 8.3% respectively. However, no definit relationships between stevioside and rebaudioside were observed in these particular experiments.

Replacement of sucrose with sugar alcohols in high methoxyl pectin(HMP) jellies were studied. HMP jellies were sweetened with 100％ sucrose, 75％ sucrose and 25％ maltitol, 50％ sucrose and 50％ maltitol, and 50％ sucrose, 25％ maltitol, 12.5％ sorbitol and 12.5％ mannitol. The effect of sugar alcohols in HMP jellies were investigted. There was only slight differences in sweetness intersity in HMP jellies. Color(p<0.05), texture(p<0.01) and preference(p<0.01) of 100fl sucrose jelly were significantly higher than other Jellies sweetened with sugar and sugar alcohols mixtures. Hunter's L(lightness), a(redness), b(yellowness) values of 100％, sucrose jellies and jellies substituted with maltitol up to 25％ were not signignificantly different. But as the ratio and the number of sugar alcohols used for substition were increased, L, a and b values had been lowered signigicantly(p<0.01). Instru-mental characteristics of jelly texture were examined. Hardness of 100％ sucrose jelly sweetened with sucrose and 3 kind of sugar alcohols were higher than others(p<0.05). As substitution ratio was higher, springiness and chewiness of HMP jellies were lowered(p<0.01). Springiness of HMP jellies indicated positive correlation with general acceptance of sensory scores at 5％ significant level. Brittleness, gum-miness and cohesiveness in all types of jellies were not significantly different.

The effects of sweeteners(fracto-oligosaccharide: xylitol: erythritol: stevioside) as alternative ingredients to sugar on the characteristics of yanggeng were investigated. The relative sweetners of fracto-oligosaccharide, xylitol, erythritol and stevioside to a 25% sugar solution were found to be 25%, 25%, 22.5% and 0.25% respectively. Sensory evaluation to compare yanggeng made using fracto-oligosaccharide, xylitol, erythritol and stevioside to a 100% sugar yanggeng revealed that they differed by 37.5%, 37.5%, 33.75% and 0.75% respectively highlight. The viscosity of yanggeng differed depending on the type of sweetener used. Sugar contents(°Brix) were the highest in sugar. The moisture contents were the highest in yanggeng made with 0.75% stevioside, while the hardness, adhesiveness, chewiness and gumminess were highest in that made with 33.75% erythritol. The springiness was highest in yanggeng made with 37.5% fracto-oligosaccharide, while the cohesiveness was highest in that made with 37.5% xylitol, and the L-values, b-values and a-values were lowest in yanggeng made with 25% sugar. Sensory evaluation, revealed that the overall preference was highest for yanggeng made with 37.5% fracto-oligosaccharide and xylitol.

Relative sweetness of sucralose, an intensive sweetener, to sucrose or fructose in binary model solution and beverage systems was examined. Sensory properties of sucralose solution, orange flavored beverage and sports drink containing sucralose were evaluated at the equi-sweetness to sucrose or fructose. Consumer acceptability tests were performed on orange flavored beverage. Relative sweetness of sucralose to sucrose was 350 and 500 in binary model solution and orange flavored beverage, respectively, while that of sucralose to fructose in sports drink was 550. All the sensory properties, except astringency, of sucralose solution examined were similar to those of sucrose solution. The sensory properties of orange flavored beverage, in which 50% sucrose was replaced with sucralose, were very close, and showed comparable or higher overall acceptability to that containing sucrose only. When fructose was replaced with sucralose in sports drink sour, salty and bitter tastes, metallic flavor, and astringency slightly increased.

This study examined the quality characteristics of Yanggaeng added with tomato powder (0, 5, 10, 15, and 20%) and oligosaccharides instead of red beans and sugar. The moisture content of tomato Yanggaeng was 45.89~33.64% and was highest in the control group. The pH ranged 3.96~6.24 and significant decreased with the addition of tomato powder. Hunter's color value, lightness (L value) were the highest in Yanggaeng added with 20% tomato powder. Redness (a value) increased with tomato powder content, except for 20% tomato powder. Yellowness (b value) significantly increased with tomato powder content (P<0.05) but decreased with 20% tomato powder. In the texture profile analysis, hardness, cohesiveness, gumminess, and chewiness significantly decreased (P<0.05) with the addition of tomato powder. Total soluble solid content ($^{\circ}Brix$) was the highest (5.16) in the control group, whereas that of tomato Yanggaeng ranged 4.46~4.92 and significantly decreased (P<0.05) with the addition of tomato powder. The antioxidative activity based on 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of Yanggaeng increased with the concentration of tomato powder, although those of Yanggaeng added with 15% and 20% tomato powder were not significantly different (P<0.05). Yanggaeng added with 5 and 10% tomato powder showed acceptable sensory properties, including color, flavor, sweet taste, sour taste, and overall quality. In terms of sensory evaluation and antioxidant activity, the results show that Yanggaeng added with 10% tomato powder was the best, but more research should be conducted in order to improve sensory acceptability.

In this study, we produced macarons by adding white bean powder at various proportions (0, 25, 50, 75, and 100%). The macarons in the 100% additive group had the highest moisture content, smallest volume, highest weight, and highest sugar and reducing sugar content. The macarons in the 50% additive group had the highest spread factor.Furthermore, their pH and acidity demonstrated the greatest air bubble stability. In the Hunter color system, by adding white bean powder, the L value gradually decreased, whereas the a and b values gradually increased. The hardness, gumminess, and chewiness decreased with the addition of white beans. Flavonoids and total phenolic compounds, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, and superoxide dismutase (SOD)-like activity were the highest at 100%. Additionally, their overall acceptability was the highest at 50%. These results suggested that the use of white bean powder to produce macarons have numerous advantages.
