The physicochemical properties, such as retrogradation, fat acidity and viscosity, on the pine nut's gruel at various contents of pine nut (0, 1, 3 and 5%) during storage at 4, 25 and $40^{\circ}C$ were investigated. The degree of retrogradation was increased rapidly at the initial storage stage. The lowest value (about 10%) of the degree of retrogradation was observed in the gruel sample containing 3% of pine nut. Also, the rate constant of retrogradation was showed the lowest value (0.0422) in the gruel containing 3% of pine nut regardless of storage temperatures. The fat acidity was showed the lower value than 30 mg KOH in all samples. The viscosity increasing velocity(RVU/min) between holding strength and final viscosity was decreased as the pine nut's content was increased. However, it was not affected by the storage temperatures.

In this study, we applied a steam treatment to black sesame to determine the optimum treatment conditions, and also examined the antioxidant effects and quality characteristics. For black sesame gruels, roasting can be used in a variety of ways in cooking to enhance functionality and preference. We found that the solid content increased with the addition of 70% steamed black sesame in the glutinous rice-black sesame gruel samples, and for glutinous black rice-black sesame gruels, solid content was highest with the addition of 50% steamed black sesame. For the chromaticity, the L-value decreased as the addition of steamed black sesame increased in all the black sesame gruels made with the steamed black sesame. With regard to texture, the cohesiveness, springiness, gumminess, chewiness, and adhesiveness of the gruels made with steamed black sesame were highest when 60% steamed black sesame was added. The results of the sensory test showed that overall preference was highest for the glutinous rice-black sesame gruel made with 60% steamed black sesame, while the glutinous brown rice-black sesame gruels were preferred with 60% and 70% additions, and the glutinous black rice-black sesame gruel was deemed best with 60% steamed black sesame. The most appropriate ratios of steamed black sesame in the black sesame gruels, with regard to overall quality, are as follows: 60% steamed black sesame for the glutinous rice-black sesame gruel, 60% and 70% steamed black sesame for the glutinous brown rice-black sesame gruel, and 60% steamed black sesame for the glutinous black rice-black sesame gruel.

Green Tea consists of 15-30% catechins (a type of polyphenol), which act as super antioxidants, inhibitory action against aging process. Antioxidants fight radical-free oxygen, an agent which can begin the process of cancer by damaging essential body chemicals and harming DNA. This study was peformed to develop the elderly diet using Green Tea as an inhibitory action against aging process. Nokchaborijook (Baley gruel added rice powder and Green Tea) was manufactured by various levels of Green Tea(1, 4, 7%) and the grinding period(15, 30, 45 sec). The optimum levels of added Green Tea and grinding periods on Nokchaborijook were determined with the results of sensory evaluation by response surface methodology and analysis of composition. The Anti-oxidant Vitamin A, C, E and Flavonoid were increased with increased levels of Green Tea and grinding periods be decreased. As the levels of Green Tea and grinding periods were increased, the green color and penetrated force became stronger. Among the sensory attributes, Bitterness, Green Tea Flavor and Hashness were greater depending on increasing Green Tea. Jujube flavor was greater relying on decreasing Green Tea. Greenness and spreadability of particles were increased as both the amounts of Green Tea and the grinding period were increased. This result was used to determine the optimum conditions of adding levels of Green Tea and grinding periods. The optimum conditions of Nokchaborijook was established as adding of 5.8% Green Tea grinded for 15 seconds.

The abilities of instant gruel manufactured with colored barley and oats to improve diabetic conditions were investigated using diabetes-induced mice and rats. Mice or rats were divided into a diabetic control group and one experimental group (seven animals per group). The control groups were fed without instant gruel and experimental groups were fed basal diets supplemented with 10% instant gruel for 8 weeks. The streptozotocin (STZ)-induced diabetic rats experimental group showed a significant decrease in food intake compared to the control group. Both Type II diabetic mice and STZ-induced diabetic rats experimental groups showed higher increases in body weight than the control groups. The blood glucose levels of the experimental groups ($352{\pm}12.2$ mg/dL in Type II diabetic mice; $296.4{\pm}13.2$ mg/dL in STZ-induced diabetic rats) were lower than the untreated control groups ($426.0{\pm}15.4$ mg/dL in Type II diabetic mice; $514.0{\pm}17.6$ mg/dL in STZ-induced diabetic rats). The serum insulin levels of Type II diabetic mice increased by 38.3% in the experimental group ($12.8{\pm}1.1$ ng/mL) compared to the control group ($7.9{\pm}0.5$ ng/mL). The immunohistochemical density of insulin-secreting cells and glucagon-like peptide-1 (GLP-1)-secreting cells in the pancreas were significantly higher in the experimental groups than the control groups for Type II diabetic mice and STZ-induced diabetic rats. Therefore, we conclude that instant gruel manufactured with colored barley and oats stimulates the secretion of insulin and decreases blood sugar by activating insulin-secreting cells in the pancreatic islets of diabetic animals.

This study investigated the quality characteristics and antioxidant effects of black sesame gruel made with different concentrations of 15 minutes of treatment at $100^{\circ}C$ roasted black sesame. Total lignans showed the highest levels with 15 minutes of treatment at $100^{\circ}C$ roasted black sesame. With regard to lecithin's antioxidant effects, 15 minutes of treatment at $100^{\circ}C$ roasted black sesame showed a higher oxidation restriction rate. Hydroxyl radical scavenging, a similar scavenging activity to tocopherol, and a comparatively higher scavenging activity than sesamol, was shown with 15 minutes of treatment at $100^{\circ}C$ roasted black sesame and showed scavenging abilities of 90% and higher. For black sesame gruels, roasting can be used in a variety of ways in cooking in order to enhance functionality and preference. The most appropriate ratios of $100^{\circ}C$, 15minutes roasted black sesame in black sesame gruels, with regard to the overall quality characteristics, are as follows: The results of the sensory test showed that the overall preference was highest for glutinous rice-black sesame gruel, glutinous brown rice-black sesame gruel, and glutinous black rice-black sesame gruel, which were deemed best with 50% black sesame. From the above results, it could be seen that glutinous rice, glutinous brown rice, and glutinous black rice black sesame gruels, which are made by adding 50% roasted black sesame, contributed to enhancing the function of antioxidant activation and development quality.
