  • Injulmi, a kind of traditional Korean sticky rice cakes, was prepared with the mixed flours of waxy and black rices in different ratio(0% to 25% black rice flour), and their quality properties were studied. In the sensory evaluation, the best acceptance was shown in the samples with 15% black rice flour. The scores for hardness, coarseness. chewiness, and flavor were increased as the added amount of black rice flour increased. The moisture content of the samples ranged from 43 to 45%, and it was increased as the added amount of black rice flour increased. In color value, lightness(L value) was 27.43∼65.63. The redness(a value) was -2.01∼4.74, and the yellowness(b value) was -1.40∼4.59. The redness and blueness were increased by the increase of black rice flour. In the texture properties, the increase of added black rice flour increased the hardness, chewiness, and gumminess of Injulml, but decreased the adhesiveness. Based on the results, the optimal recipe for Injulmi added black rice flour was to make with 85% waxy rice flour ant 15% black rice flour.

  • Dried plantain (Plantago asiatica L.) was evaluated as a natural food preservative. The methanol extract of dried plantain at tie concentration of 2,000$\mu\textrm{g}$/ml completely inhibited the growth of B. subtilis, L. monocytogenes and V. parahaemolyticus. When the extract was added to noodles and rice cakes at the concentration of 1, 3 or 5%, less microbial growth was observed compared with the control group. While the noodles with 1% plautain extract were evaluated favorable in terms of color, chewiness and overall guality, 3% addition of the extract gave the best score for rice cakes.

  • To investigate the food choices and Dietary Preferences of College Women the number of dishes sold and the sales of the midmeal at the Student Cafeteria, Ewha Womans University were recorded for the fiscal year of 1974; and the observations were made on two consecutive days (June 3rd and 4th, 1974)on what a person has chosen which and how many dishes. The relationship between the number of the consecutive days and the number of foods chosen were treated as Chi square analysis. The results of the food choices and dietary preferences of College Women were as follows: 1. Breads and rice cakes, vegetable dishes, milk and milk products, rice dishes, soups, meat, fish, poultry and eggs, Kimchis and one dish meal were chosen highly; and beverages, stews, and soybeans and soybean products were chosen negligibly. 2. One dish meals, vegetable dishes, meat, fish, poultry and eggs, milk and milk products showed the highest sales volume during the year; rice dishes, breads and rice cakes were the second highest in sales amount; fried foods, snacks and Kimchis showed the range of $3{\sim}6%$ of the total sales; and the beverages, stews, soybean and soybean products were the lowest in sales amount. 3. Seasonal differences were noticed on some dishes. Breads add rice cakes, milk and milk products showed the high selections from March to November and the low, during December to February. Stews, Kimchis, beverages were kept low except sudden rise on February. One dish meal and rice dishes showed almost same level during the year but on February the slight increase were noticed; even level were kept on meat group except the increase to $13{\sim}16%$ on July and December. Fried foods were kept on similar level during the year except the increase on June. Snacks and fruits showed low selections on March, April, November and December and higher at summer. Vegetables, soups, soybean and soybean products showed no different fluctuations in selections during the year. 4. Rolls, salads, milk, hamburgers, fried vegetables, rice with mired vegetables(Bi-bim-bab), and Nang-myun were the single dishes chosen most frequently. 5. There is significant relationship at 0.05 level between the consecutive days and the number of foods chosen. It is concluded that about 50% of the population has taken one item of dishes. The popular combinations were one dish meal and soup or Kimchi; noodles and salads or fried vegetables. It is suggested to set up choice menus with the daily variations, cyclical variations and with the invariable ones; and to recommend one dish meal, breads, partial meals for school lunch; and to study to improve one dish meal, vegetable dishes and fried foods, which are new and inexpensive products. It is also suggested that the feeding of the college students should have to lead the people to the goal that the nutrition education is desired.

  • The purpose of this study was to investigate the instrumental and sensory characteristics of coffee-sulgi(rice cake) with different ratios of the ingredients; coffee(30$m\ell$, 40$m\ell$ and 50$m\ell$ of espresso and instant coffee) and sugar (50g and 75g). A commercial scheme for coffee-sulgi was also investigated. The optimal mixing ratios of coffee-sulgi with added espresso were rice flour 500g, salt 5g, espresso 40$m\ell$ and sugar 75g. Those of coffee-sulgi with added instant coffee were the same. As the sensory intensities of coffee aroma, coffee taste, sweetness, moistness, elasticity, color acceptance for coffee-sulgi and overall acceptance for quality were enhanced, the overall preference for coffee-sulgi was increased. In addition, overall preference was positively correlated with adhesiveness and a-value of instrumental characteristics, but negatively correlated with cohesiveness and L-value. In coffee-sulgi with added espresso, intensities of coffee aroma, browniness, coffee taste, color acceptance for coffee-sulgi, overall acceptance for quality and overall preference were higher than those of coffee-sulgi with added instant coffee. In this point, gourmet coffee-sulgi with added espresso and universal coffee-sulgi with added instant coffee could be differentiated in the coffee-sulgi markets. In conclusion, this study of coffee-sulgi and the differential scheme for the market will be useful to expand rice processing, enhance the intake of rice cakes and provide a reference for the commercialization of rice cakes.

  • Texture and descriptive sensory characteristics of a Korean rice cake (Karedduk) with added mixtures of fructooligosaccharide (95%) and emulsifier, Sodium Stearoyl Lactylate-90 (SSL-90), were investigated after 2 and 24 hr of storage at $5^{\circ}C$. A central composite design was used for the arrangement of treatment. Different levels of fructooligosaccharide (95%), 0, 3, 6, 9, and 12%, were added to dry rice flour. Also, different levels of emulsifier, 0, 0.3, 0.6, 0.9, and 1.2%, were added to the same dry rice flour. The texture properties analysis using a Texture Analyzer revealed that the chewiness, gumminess, and hardness were significantly different. The effect of retarding retrogradation of Korean rice cakes (Karedduk) with added mixtures of fructooligosaccharide (95%) and SSL-90 showed an increasing trend as the amount of fructooligosaccharide (95%) increased. Overall, the instrumental texture properties were highly correlated with the sensory characteristics. The results suggested that Korean rice cakes (Karedduk) with the addition of a mixture of fructooligosaccharide (95%) and SSL-90 can be made from the mixture of 9% fructooligosaccharide (95%) and 0.9% SSL-90 in order to retard starch retrogradation.

  • To make rice cake with squid ink, the squid ink dilulted in fifteen times was added to rice flour in the ratio of 0%, 2%. 4%, 6% and 8% respectively. Then, the squid inky rice cake was tested in physical function and chromaticity. Rheometer test was also included in this experiment. In physical function test, it showed that the inky rice cake with 6% and 8% ratio was the best in preference. In the chromaticity test, as the adding ratio of squid ink increases, the brightness decreased. The red and yellow brightness of 8% inky rice cake showed high. The results of rheometer test are as follows. In hardness, the inky rice cake with 2% adding ratio was high and the 6% inky rice cake was low. In cohesiveness, the 0% inky rice cake was high and the 8% inky rice cake was low. In gumminess, the 2% inky rice cake was high and the 6% inky rice cake was low. In brittleness, the 2% inky rice cake was high and the 6% inky rice cake was low. With correlation analysis, 1 could reach the following. The overall quality of inky rice cake was correlated with all test items except chewiness. The moistness was correlated with flavor, grain and chewiness. Also, the 8% inky rice cake was correlated with the inky rice cakes with the other adding ratios in all aspects of test.

  • This research was conducted to improve availability of agricultural by-products, national natural resources that could be used as fertilizer source, by estimating the amount of production and collecting main contents of fertilizer substances from previous studies and data, in order to be used as basic data to investigate national resources that could be used as alternatives for imported oil-cakes in the future. Conversion factor was used to estimate annual production of agricultural by-products for main 34 crop types in 2018. For total agricultural by-products, rice straws accounted at 50.3% for the highest proportion, followed by 8.7% of rice husks, showing that by-products from rice harvest accounted at 59.0% for all by-products. Further, there were listed the contents of fertilizer substances (nitrogen, phosphoric acid, potash) in 40 types of by-products from agricultural areas. The average contents of nitrogen, phosphoric acid, and potash in agricultural by-products were 1.43%, 0.59%, and 1.90%, respectively. As a result of estimating the annual nitrogen supply amount from 26 agricultural by-products in 2018, it was found that it could supply 44,911 tons of nitrogen. The investigated by-products contained fertilizer substances such as nitrogen, phosphoric acid, and potash, but the contents were lower compared to castor oil-cake used as main component of organic fertilizer. Therefore, resource management plan needs to be established for efficient use of by-products because time, location, and nutrient content of agricultural by-product production were extremely different. Research on fertilizer and manure using agricultural by-products need to be conducted to develop and distribute alternatives for imported oil-cakes.
