The present study was conducted to supply more scientific information for standardization of preparation method of Gyungdan and to determine the standard for manufacturing procedure adapted with mechanically impacting technology (MIT) for mass production. The optimum preparation condition for non-waxy Gyungdan adapted with MIT was 35% of water, 0.5% of wheat flour (w/w of soaked rice), and mechanically impacting for 10 min at 450 rpm. In the present study, standardization of manufacturing procedure for merchandizing of Gyungdan was established with width, weight, and height. Average of Gyungdan adapted with MIT at 90 rpm (stuffing speed) and 46.58 Herz (cutting speed) is 18.3 g of weight, 28.4 mm of height, and 32.4 mm of width. Hardness, as a main parameter of texture profile, of Gyungdan was maintained lower than 100 g up to 3 days at the storage of $20^{\circ}C$ and up to 70 days at the storage of $-20^{\circ}C$. And, it was performed to develop rice cake as meal-replacement adapted with MIT and sub-ingredients such as strawberry, pumpkin, and mugwort. Gyungdan prepared under controlling manufacturing condition of MIT was supplemented with 0-1.6% of sub-ingredients, respectively. In sensory tests, the best substitute ratios of strawberry, pumpkin, and mugwort were 1.6%, 0.8%, and 1.6%, respectively. With the results above, not-harden Gyungdan supplemented with sub-ingredients and various stuffs can be expected to application for wheat-substitute meal-replacement.

This study investigated the quality and antioxidative properties of a Korean fried rice cake, Gaeseong-Juak (doughnut of waxy rice) added with Prunus yedoensis Matsumura (PYM) extract, vitamin C and BHT. Gaeseong-Juak was prepared by adding PYM extract at 0, 0.5, 1, and 2% of waxy rice powder. The moisture contents of Gaeseong-juak added with PYM extract varied between 17.50% and 21.70%. Among the samples, the lowest moisture content was 2% Gaeseong-juak added with PYM extract. The contents of the samples obtained from crude protein, crude fat, crude ash were 4.47~4.73, 11.15~12.50, and 0.73~0.82%, respectively. The as the content of PYM extract increased, L-values significantly decreased while a-value and b-value significantly increased (p<0.001). The texture profile analysis of the Gaeseong-Juak was not significantly different at the samples. In the sensory test, the sample containing 0.5% PYM extract obtained good scores. The antioxidative effect of the Gaeseong-Juak significantly increased as the addition level increased, compared to the original Gaeseong-Juak (p<0.001). From these results, we suggest that PYM is a good ingredient for increasing the consumer acceptability and the functionality of Gaeseong-Juak.

단백질 함유량은 유색미가루가 밀가루보다 적지만 현미가루보다는 함유량이 많았고, 지방함량과 회분함량에서는 현미와 비슷하였다. 현미가루는 유색미가루보다 peak viscosity, holding viscosity, breakdown viscosity, final viscosity에서 높았을 뿐만 아니라 setback viscosity에서도 높았지만 유색미가루는 호화점도에서 현미가루 뿐만 아니라 밀가루보다도 월등히 낮았다. 현미가루와 흑미가루는 5.3~6.4%의 총 식이섬유를 함유하였으나 수용성 식이섬유의 함량은 낮은 반면 주로 불용성 식이섬유를 함유하였다. 건조면과 조리면의 cutting force는 현미가루와 유색미가루의 혼합비율을 높이면 감소하였고 조리면의 경우에는 찰흑미가루 10%와 화성현미가루 20%를 첨가했을 때 밀가루 100%로 만든 대조군과 큰 차이가 없었다. 국수의 기능성을 높이고 기호도를 향상시키기 위하여 현미가루와 유색미가루를 10~30%를 첨가하여 관능검사를 실험한 결과 현미가루 20%와 찰흑미가루 20%를 첨가한 국수가 가장 높은 관능적 평가를 받았다.

This study was carried out to build a database system for amylose and protein contents of rice germplasm based on NIRS (Near-Infrared Reflectance Spectroscopy) analysis data. The average waxy type amylose contents was 8.7% in landrace, variety and weed type, whereas 10.3% in breeding line. In common rice, the average amylose contents was 22.3% for landrace, 22.7% for variety, 23.6% for weed type and 24.2% for breeding line. Waxy type resources comprised of 5% of the total germplasm collections, whereas low, intermediate and high amylose content resources share 5.5%, 20.5% and 69.0% of total germplasm collections, respectively. The average percent of protein contents was 8.2 for landrace, 8.0 for variety, and 7.9 for weed type and breeding line. The average Variability Index Value was 0.62 in waxy rice, 0.80 in common rice, and 0.51 in protein contents. The accession ratio in arbitrary ranges of landrace was 0.45 in amylose contents ranging from 6.4 to 8.7%, and 0.26 in protein ranging from 7.3 to 8.2%. In the variety, it was 0.32 in amylose ranging from 20.1 to 22.7%, and 0.51 in protein ranging from 6.1 to 8.3%. And also, weed type was 0.67 in amylose ranging from 6.6 to 9.7%, and 0.33 in protein ranging from 7.0 to 7.9%, whereas, in breeding line it was 0.47 in amylose ranging from 10.0 to 12.0%, and 0.26 in protein ranging from 7.0 to 7.9%. These results could be helpful to build database programming system for germplasm management.

This study was performed to find out starch properties of rice grains in three varieties with different amylose content, Ilpumbyeo (non-waxy), Goami2 (high amylose), and Hwasunchalbyeo (waxy rice). There was no difference among physico-chemical characteristics of rice grains, but Goami 2 showed $2{\sim}3$ folds higher crude fat (1.36%) than Ilpumbyeo. Pasting properties of RVA showed the highest values of maximum viscosity, breakdown, and final viscosity in Ilpumbyeo. A similar chain length distribution of amylopectin was found in Ilpumbyeo and Hwasunchalbyeo, indicating that DP 12 had the highest distribution. Goami 2 had the highest distribution in DP 14, and showed the lower percent (14.1%) than other rice cultivars. Thermal properties of DSC showed that the values of Tc and Tp of Hwasunchalbyeo were similar to Ilpumbyeo, whereas a slightly higher Tc was observed. The absorbtion enthalpy was also the highest (11.1 mJ/mg) in Hwasunchalbyeo. Goami 2 showed higher To, but the lowest enthalpy (6.52 mJ/mg) compared to Ilpumbyeo (7.92 mJ/mg). Retrogradation properties, which were measured with the gelatinized rice sample used for DSC, and stored in $4^{\circ}C$ during 6 days, indicated that retrogradation absorbtion peak was the first peak at $52.6{\sim}55.2^{\circ}C$, and the second peak above $95^{\circ}C$. Retrogradation enthalpy of Goami 2 was the highest value (5.12 mJ/mg).

Purpose: To improve the cooking quality of brown rice, newly inbred soft rice cultivars were investigated. Methods: The physicochemical properties of brown rice flour and water absorption patterns and cooking characteristics of brown rice grain were compared to Ilmi white and brown rice. Results: General composition and total dietary fiber contents of five rices were significantly different with higher ash, protein, and total dietary fiber contents in soft brown rice than white rice. The hardness of raw rice grain was higher in Ilmi brown rice than in soft brown rice. The water absorption increased rapidly in 30 min of white rice and in 4-6 h of brown rices. The apparent amylose content of soft brown rice was lower than that of Ilmi rice. The initial pasting temperature and all viscosities were significantly different, but the trend was not similar. The textural properties of hardness and roughness were higher, but adhesiveness, cohesiveness, and stickiness were lower in Ilmi brown rice than white and soft brown rices. In sensory preference test, not only textural properties, hardness, adhesiveness, cohesiveness, stickiness, and roughness, but also color, glossiness, and roasted flavor were higher in soft brown rices. Especially soft brown rice B showed the best cooking quality among all rices. Conclusion: The results of the study suggested that soft brown rice is developed for cooking with high nutritional and functional quality.

The contents of“Joo-chan”consist of eighty two items about alcoholics, a number of side dishes and soybean sauces. Interpreted content was classified and analyzed. Selected 52 items among those brewages, artless-brewing alcoholics, were distributed into 6 large patterns. The materials used for brewing artless alcoholics were regular rice, waxy rice, wheat and yeast(NURUK). Six patterns, grounded on these materials, were set one thing to another and analyzed.
