The effect of agglomeration treatment was examined to prevent the parched cereal powder from clumping when it is blended with water. Parched cereal powder was composed of 66.9% carbohydrate, 7% water, 12.1% crude protein, 12.1% crude fat and 1.9% ash, respectively. Particle size of parched cereal powder was generally enlarged by agglomeration treatment. This phenomenon was confirmed by particle size analyzer and microscopic observation. The color of agglomerated sample was shown to be slightly darker than the untreated sample. The water absorption indices of agglomerated samples which were steamed for 2min and re-dried were significantly increased as compared with the untreated sample. The water solubility indices of agglomerated samples showed generally lower values than those of untreated samples. In views of quality and processing time, the optimum condition of agglomeration treatment for manufacturing well-dispersable parched cereal powder in water was 15min re-drying after 2min steaming. It is concluded that the agglomeration treatment improves the dispersibility of parched cereal powder and thus facilitates the intake of it after mixing with water.

This study was conducted to assess the dietary intake of college students in Gyeonggi-do. The dietary survey data were obtained by a semi-quantitative food frequency questionnaire given to 103 students, 56 males and 47 females. The average age the of subjects was 22.5 years old for the male students and 20.9 years old for the female students. Among the subjects, 38 males and 26 females' height, weight and percentage of body fat were measured using Inbody 3.0. The average height, weight, Body Mass Index(BMI) and percentage of body fat of the subjects was 173.1cm, 68.6 kg, 22.9 and 18.9% for males and 162.5 cm, 54.1 kg, 20.5 and 28.1% for females, respectively. The mean daily intake of energy was 2,343.0 kcal for males and 2,062.0 kcal for females. The average intake of protein, carbohydrates, Vitamin B1 in the male students were significantly higher than those of the female students(p<0.05). The average of Nutrient Adequacy Ratio(NAR) was ranged from 0.60(folate) to 0.99(phosphorus). NAR of Vitamin A and calcium was 0.71 and 0.75, respectively. The average of Mean Adequacy Ratio(MAR) was 0.85. The intake of rice and oriental cereals(sum of the parched cereal powder, ramen, noodles, Chajangmyon, buckwheat vermicelli, buckwheat noodles, dumplings and rice cakes) in the males was significantly higher than those of the females. The intake of snacks in the females was significantly higher than that of the males. Appropriate nutritional education for an optimal intake of nutrients may help to improve the quality of diet in college students.
