Turanose is a potential candidate for use as a functional sweetener because of its gentle taste, low calorie, and non-cariogenicity. The aim of this study was to replace sucrose with turanose to produce health-beneficial maesil-cheong. Quality effects of turanose on maesil-cheong were evaluated by determining the contents of free sugars, organic acids, amygdalin, and antioxidant activity. The pH and Brix values of sucrose- and turanose-based maesil-cheong remained at the same level between 2.83 and 3.00 and 54.6-58.6°Bx, respectively, after 90-day storage. Among oxalic, malic, and citric acids, citric acid content was the highest in both maesil-cheong samples. Turanose did not significantly hydrolyze in maesil-cheong, whereas sucrose was completely hydrolyzed to glucose and fructose. Thus, turanose is suitable for the development of acidic maesil-cheong to improve its health promoting effect. Turanose showed product qualities similar to sucrose-based maesil-cheong. Turanose can be used as a functional sweetener or bulking agent in processed foods.

This work was carried out to investigate the effects of rice hull continuously utilized and/or replenished on the composting properties and to obtain the fundamental data between an unsupported wall and a soil supported wall during the period of composting with pig slurry in winter season. There were no the temperature holding effects in soil supported wall. New compost facility design for the temperature holding effects from a soil supported wall was required. The results were as follows; 1. Composting 1㎥ of pig slurry caused to save on 0.31㎥ of bulking agent in the unsupported wall in comparison with a soil supported wall in the rice hull single addition, and 0.45㎥ in the rice hull gradual addition. 2. The pile in the rice hull single addition had a high temperature in 4 days of composting indicating $71^{\circ}C$ and had a tendency in repeating periodically between $40^{\circ}C$ and $65^{\circ}C$ till 43 days of composting. And also the temperature of the pile was maintained between $48^{\circ}C$ and $28^{\circ}C$ after 50 days of composting. The pile of a rice hull gradual addition had the lower point of the temperature high increasingly according to adding up rice hull during the 35 days of composting. 3. The pH recorded in the rice hull single addition was higher(8.35∼10.02) compared to the rice hull gradual addition(8.6∼9.8). The pile of a rice hull single addition had a tendency in abruptly decreasing pH of the unsupported wall during the period of between 0.363$\textrm m^3$ and 0.537$\textrm m^3$ as a unit of pig slurry per rice hull. EC depending upon the way in adding rice hull was changed between 1.10 mS/$\textrm {cm}^3$ and 1.87 mS/$\textrm {cm}^3$. 4. The organic matter in an unsupported wall of the hull single addition was maintained the level of 55% during the period between 0.119㎥ and 0.363㎥ as a unit of pig slurry per rice hull while in the soil supported wall between 48 and 70. Water soluble C:N ratio was maintained between 1 and 2 in the rice hull single addition, while between 1 and 3 in the rice hull gradual addition. 5. Fertilizer constituents were detected higher level in the unsupported wall than in the soil supported wall in all treatments. This was dependant upon the input of pig slurry.
