The purpose of this study was to investigate the quality of sugar-snap cookies containing various types and mixture ratios of sugar. The characteristics of sugar-snap cookies prepared with fructose, high-fructose corn syrup and invert sugar were examined through physical properties measurement and sensory evaluation. Results of the investigation suggest significant differences in the cookies made with various sugars. High-fructose corn syrup was better than others for making sugar-snap cookies. The quality of cookies baked with high-fructose corn syrup was improved compared to cookies baked with invert sugar or fructose. Varying the formula, with high-fructose corn syrup had little or no effect on the quality of the final product. Using different quantities of invert sugar and high-fructose corn syrup significantly affected the physical properties of the cookies. Sugar-snap cookies containing invert sugar had an extremely positive effect.

The acute toxicity of palatinose and palatinose syrup was assessed in Sprague-Dawley rats. Palatinose and palatinose syrup, when administered orally at the doses of 27 g/kg, did not cause any death. Although the decrease in weight gain was observed in males treated with palatinose syrup, it did not have any toxicological importance. There were no significant changes in hematological and biochemical parameters. From these results, it was concluded that palatinose and palatinose syrup did not induce any remarkable toxicological symptoms and the $LD_{50}$ is >27 g/kg by oral administration in Sprague-Dawley rats.

The purpose of this research is to study comparatively what the effects will be to the sensory characteristics and texture of Yackwa when the soaking time in syrup varies from 5 minutes, 1 hour, 2 hours, 3 hours, 5 hours and 12 hours. Evaluation was conducted through sensory evaluation and instrumental test by Instron. In results obtained were as follows. 1. In sensory evaluation, color of Yackwas by 1 hour or 2 hours soaking in syrup were better than other sample. Shape of Yackwas by 2 hours or 3 hours soaking in syrup were better than other sample. As the soaking time increased softness of Yackwa tended to increase. Otherwise as the soaking time decreased, fracturability tended to be good. In taste, Yackwa by 1 hour soaking in syrup was the best. 2. Instron measurement indicated that Hardness, Springiness and Chewiness tended to decrease as the soaking time in syrup increased. But Cohesiveness did rot have much effect the soaking time in syrup. 3. Softness and Fracturability of Yackwa had significant relationship with Hardness ana Springiness. Therefore Hardness and Springiness represented the texture of Yackwa. In view of the above results, it came to the conclusion that Yackwa by soaking time in syrup for 1 hour or 2 hours could give the best results among the groups studied.

In efforts to use pine needle extract as a substitute for sugar, fermented pine needle extract syrup was added to the wheat flour nea in the manufacture of white bread The extract was added to levels of 8.3%, 11% and 18% of total weight based on the Brix degree of the dough The cohesion of each dough was checked, and the physical properties and storage stabilities of the baked breads were analyzed during storage at mom temperature. Analysis of the cohesion of each dough by farinogram showed that dough with pine needle extract was better than dough with sugar, in terms of both stability and durability of mixing. The pH of dough with syrup was steady during storage at pH 5.4 5.8, which is favorable for yeast activity. The dough with syrup also showed low firmness and good extensibility, both of which would favorably affect gas retention on fermentation. Increases in syrup addition resulted in higher product volumes. Bread with syrup was slow to increase in hardness during storage, suggesting that higher syrup concentrations inhibited development of staleness. The addition of syrup also inhibited the growth of aerobic bacteria and mold on the bread surface. The addition of syn did not cause any negative effect. The use of pine none extract syrup may thus contribute to improvements the physical properties, the storage stability, and the hygienic quality of bread.

This study investigated the changes in textural characteristics that occurred by adding maltose syrup, dextrin, and sucrose to whole egg gels, by assessing coagulation after cooling. It also examined the optimal NaCl and sucrose concentrations for whole egg gels sensory evaluations, and then studied how the addition of sucrose effected gel formation and textural characteristics under optimal NaCl concentration. The additions of maltose syrup, dextrin, and sucrose, presented some color changes. The greater the addition of maltose syrup or dextrin, the lower the L, a, and b values of the whole egg gel and whole egg liquid, and ultimately the color turned dark bluish green. With increasing additions of sucrose, maltose syrup, and dextrin, the viscosity of the whole egg liquid increased slightly. In terms of the mechanical texture characteristic of the gel, the texture was most elastic with the 0.8% addition of sucrose, and hardness decreased by increasing the ratio of added sucrose. Increasing amounts of maltose syrup resulted in less hardness and SF. And for dextrin, the SF increased up to 2.5 and then decreased, and hardness decreased with increasing amounts of dextrin. Based on sensory evaluations, the 0.8% addition of NaCl was significantly preferred(p<0.05), in terms of salty taste. The overall preference scores indicated that the whole egg gel made with 0.3% sucrose and the optimal NaCl concentration(0.8%) was most preferred, and each sample was significant(p<0.05). Under the optimal 0.8% NaCl concentration increasing the sucrose concentration resulted in a darker egg gel color, in terms the L value. SF, NF, and hardness, which are mechanical texture parameters, were when 0.8% sucrose and the optimal NaCl concentration of 0.8% were added to whole egg liquid, in preparing the whole egg gel.

The purpose of this study was to measure the blood glucose level and glycemic index (GI) in response to persimmon (Diospyros kaki Thunb) syrup extracted from persimmon and extract of persimmon by-products. Major component analyses of persimmon syrup I (PSI, 95:5 mixture of purified persimmon syrup and non-purified persimmon syrup) and persimmon syrup II (PSII, 50:50 mixture ratio of purified persimmon syrup and non-purified persimmon syrup) were $0.3{\pm}0.1$ and $0.6{\pm}0.2$ mg/g for total polyphenolic compounds and $70.6{\pm}0.6$ and $66.6{\pm}1.6%$ for total carbohydrates, respectively. Blood glucose responses of PSI and PSII were determined using both normal ICR mice and streptozotocin (STZ)-induced diabetic male Sprague-Dawley (SD) rats. Further, oral glucose tolerance test (OGTT) was performed on diabetic rats to assess the effects of the experimental diets. Blood glucose response and OGTT showed that blood glucose levels were significantly lower in mice and diabetic rats fed PSI and PSII compared to those fed diets of sugar, maple syrup, or honey. The GIs of healthy volunteers in response to PSI and PSII were calculated to be 51.9 and 35.7, respectively. On the contrary, the GIs of healthy volunteers fed diets including sugar, maple syrup, or honey were 52.6, 20.0, and 93.0, respectively. These results suggest that persimmon syrup can be used for both the treatment of diabetics and healthy people due to its beneficial effects on blood glucose level.

Action of a cyclodextrin glycosyltransferase (CGTase) produced from alkalophilic Bacillus sp. No.4 was studied in a solution containing starch and sucrose to prepare glycosyl sucrose syrup with good sweetness and antidecaying properties of teeth. In the initial stage of the reaction the CGTase produced cyclodextrin, however, the cyclodextrin disappeared and glycosyl sucrose was formed with the lapse of reaction time. The best proportion of sucrose to starch for prodution of glycosyl sucrose was about 1 : 1. The optimum pH and temperature of the coupling reaction was pH 6.0 and $60^{\circ}C$, respectively. Main composition of glycosyl sucrose syrup prepared with 20% starch and 20% sucrose was sucrose 18%, glucosyl sucrose ($G_{2}F$) 15.3% and maltosyl sucorse ($G_{3}F$) 11.3%. And glucose, maltose and maltotriose were produced very little. Smaller amounts of acid and insoluble glucan were formed in the syrup by Streptococcus mtans OMZ176 than in the sucrose. Therefore, the prepared glycosyl sucrose sucrose syrup is expected to prevent teeth from decaying.

This study investigated the quality characteristics of baked rice cake added with maltitol syrup. The hardness, adhesiveness, cohesiveness, gumminess, and chewiness of baked rice cake significantly decreased (P<0.05) according to the level of added maltitol syrup. Hunter's color values of baked rice cake did not differ significantly according to the level of added maltitol syrup. Sensory evaluation indicated that appearance, moistness, chewiness, hardness, and overall acceptance of baked rice cake prepared with added maltitol syrup were improved compared to those of baked control rice cake. Hunter's color values and texture properties of baked rice cake added with 10% maltitol syrup were compared with those of baked control rice cake during storage at room temperature for 3 days. Hunter's color L values of baked rice cake decreased during storage, whereas a and b values increased. The rate of hardness increase in baked rice cake with maltitol syrup was lower than that in baked control rice cake during storage. The Avrami exponents (n) of baked control rice cake and baked rice cake added with 10% maltitol were 2.418 and 2.098, respectively. The time constants (1/k) of the former and latter were 43.860 and 60.976, respectively. Overall, addition of 10% maltitol syrup improved the texture, sensory properties, and retarding retrogradation of baked rice cake.

Fish-frames, which are left after obtaining fillets or muscle during fish processing, consists of useful food components, such as muscle, collagen, calcium, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This study was carried out to prepare snack using conger eel frame (SF) for human consumption and also to elucidate food component characterization of the snack. The results of volatile basic nitrogen suggested that conger eel frame was a suitable material for preparing snack. Based on the results of sensory evaluation and costs, starch syrup was an optimal sweetener for preparing snack using conger eel frame. The starch syrup-treated SF appeared safe because the moisture content and peroxide value were below the safety limits described in the guideline of Korea Food and Drug Administration (KFDA). Starch syrup-treated SF was similar in the pattern of fatty acid composition to soybean oil, whereas EPA and DHA were detected in SF. The total content of amino acid in starch syrup-treated SF was 23.9% based on 100 g of raw material. The maj or amino acids were aspartic acid, glutamic acid, glycine and alanine. The total contents of calcium and phosphorus in starch syrup-treated SF were 4.9% and 2.8%, respectively. The Ca/P of starch syrup-treated SF was 1.9, which is a good ratio for absorption of calcium. The SF made with starch syrup was superior in EPA and DHA compositions, total amino acid, calcium and phosphorus contents to commercial snack using eel frame.
