  • The textural characteristics of nonxaxy rice flour gels and rice cake(Injolmi) with different water contents and additives were evaluated after freezing and microwave heating. As moisture content of rice flour gels increased from 45% to 55%, its hardness and gumminess decreased, but adhesive and cohesiveness had no significant difference. Microwave heating did not markedly affect the texture but frozen storage was very effective to prevent the hardening of products. Hardness of reheated rice gels increased more rapidly in non-packaged sample than in PE wrap film and affected by storage time of 24hrs at 20$^{\circ}C$. As sugar content of rice flour gels increased from 0% to 10%, its hardness, adhesiveness, and gumminess decreased, while cohesiveness did not change.

  • The purpose of this study was to investigate the effects of the addition of various amounts (0, 1, 3, 5%) of Mokdanpi(P. suffruticosa) powder on the shelf life and the physicochemical, sensory characteristics of rice cakes and noodles to examine the possibility of using Mokdanpi as a natural food preservative for food products. The decrease in the moisture content of rice cake and noodle samples during storage was much less in Mokdanpi-added groups than the control group. The color L value increased and a and b values decreased in the rice cake samples, and color L value, b value decreased and a value increased in the noodle samples during storage. The microbial growth was less in Mokdanpi-added groups than the control group. In sensory evaluation, there were no significant differences among the control and 1, 3%-added groups in terms of color, flavor, taste, moistness, cohesiveness and overall quality; however, 5%-added groups received significantly less score than others (p<0.05). As the storage time increased, the sensory scores decreased significantly in the control and 1 %-added groups of both rice cakes and noodles (p<0.05), but no changes were observed in 3, 5%-added samples. The results suggested that Mokdanpi is effective in increasing the shelf life and inhibiting the staling of rice cakes and noodles.

  • The purpose of this study was to improve the palatability of fermented red pepper soybean paste (Kochujang). Five individual models of Kochujang were prepared the following: control, glutinous rice containing 50% (A) and 100% (B) of barley, glutinous rice containing 1.5% (C) and 3.0% (D) of red rice. These Kochujangs were prepared and fermented for 60 days at 30 in a crock, and examined for changes in their physicochemical properties. There were no distinguishable change in their pH, acidity, formol-N content. L (lightness)-, a (redness)- and b (yellowness)-values were decreased rapidly until 20 days of fermentation. After 60 days, the values of L-, a- and b- of A, B Kochujang were increased than those of control, C, D Kochujang. Sensory profiles of color, flayer, taste and overall quality on the final products which fermented for 60 days showed that there were no differences in quality of each models. HMG-Co A reductase inhibitory activities were observed in 1.5% of red rice containing Kochujang.

  • This study analyzed the general components of rice bread with 75% rice content such as water, crude ash, crude protein, crude fat and carbohydrate, and its nutrients such as vitamin C, vitamin A, vitamin E content, minerals, amino acids, and fatty acids. The contents of crude protein were high and those of crude fat were low with the contents of crude ash, crude protein, and crude fat being 1.61, 18.50, 0.04 g/100 g respectively. Vitamin A was not detected and the contents of vitamin C and vitamin E were 3.85 and 3.04 mg/100 g, respectively. The calcium, potassium, magnesium, iron and sodium contents were 222.0, 117.90, 24.12, 2.30, 555.90 mg/100 g respectively. Rice bread contains 9 essential amino acids such as valine, leucine, isoleucine, methionine, threonine, lysine, phenylalanine, histidine, and arginine. The analysis of rice bread fatty acid showed 58.04 mg/100 g of saturated fatty acid, 26.31mg/100 g of monounsaturated fatty acid and 15.64 mg/100 g of polyunsaturated fatty acid. The total essential fatty acid content was 15.49 mg/100 g. With the rising interest in processed rice products, well-being, and diet, it is necessary to develop processed rice foods that are nutritional and low in calories using rice powder that is nutritionally better than flour.

  • 천연색소를 함유한 유색식물체 분말(울금, 복분자, 백련초, 홍피망, 녹차, 단호박, 뽕잎)과 찹쌀분말에 1, 3, 5% 첨가하여 호화시켜 L. lactis 젖산균으로 배양한 약초부각용 발효 찹쌀풀의 품질특성을 조사하였다. 총당과 환원당은 젖산균으로 발효시킨 발효찹쌀풀이 대조구인 생찹쌀풀에 비하여 높은 경향이었다. 총산도는 유색식물체 분말농도를 증가시킨 젖산균 발효풀에서 점진적으로 증가되었는데, 단호박($1.02{\sim}1.56%$), 홍피망($0.96{\sim}1.87%$)에서 $3{\sim}4$배 크게 나타났다. 점도는 젖산균으로 발효시킨 찹쌀풀에서 모든 비발효 찹쌀풀에 비하여 아주 낮은 값을 나타내었는데, 울금과 백년초의 분말을 이용한 비발효풀의 점도는 $100{\sim}160{\times}10^4mPa{\cdot}s$ 범위로 매우 높은 값을 나타내었으나, 복분자와 녹차는 $40{\times}10^4mPa{\cdot}s$ 이하로 낮은 값을 나타내었다. 색차계 색도의 명도(L)는 대조구인 비발효 찹쌀풀에 비하여 발효찹쌀풀은 약간씩 감소되었고, 황색도(b)는 울금과 단호박이 가장 높았으며 젖산균 발효에 따라서 대부분의 색소분말은 황색도가 약간씩 증가하였다. 그리고 복분자 분말을 첨가하여 발효시킨 찹쌀풀은 대조구에 비하여 기공의 형태가 일정하며 기공의 수가 많았다. 발효약초부각은 시판되는 해조류 부각보다 부드럽고 형태와 색상이 개선된 잠재적 기능성부각으로 판단된다.

  • The informations concerning knowledge, value and consumption pattern for rice foods of elementary schoolchildren (630 boys and 550 girls in 5th or 6th grade) were investigated in Changwon and Gimhae of Gyeongnam province. They were asked based on knowledge, one’s value and intake frequence of rice foods by questionnaries. Menus for 3 days including 2 weekdays and 1 weekend day were taken from 136 students (77 boys and 59 girls) in two Elementary Schools in Changwon and Gimhae to know intake reality of rice product. The purpose of this survey was to find the way of encouraging rice intake and preference which now seemed to be low because of simplified, westernized eating habits, and to provide basic information needed for inheriting and improving our traditional cooked rice centered eating culture. The results are summarized as follows. The knowledge of rice was positively correlated to the one’s value (r=0.365, p<0.001) and the preference (r=0.132, p<0.001), the one’s value was positively correlated to preference (r=0.409, p<0.001). The score of knowledge for rice was 12.8 points out of 20, the girls get points(13.12) significantly higher than the boys (12.53) (p<0.01). One's value about rice foods was 37.35 points out of 50 what is relatively high. They have eaten cooked rice type food for 2.24 times per day. Both boys and girls in Changwon and Gimhae area were having cooked rice type food significantly more during weekdays compared to weekends (p<0.001) by 3 days food record. According the results, we can see the possibility that schoolchildren can be encouraged to eat more rice foods by nutritional education to go with the development of various programs.

  • Microwave 처리가 쌀가공 부산물로 발생하는 왕겨와 미 의 항산화능에 미치는 영향을 조사하였다. 100 W, 200 W, 440 W의 출력으로 microwave를 처리하였을 때, 출력과 처리시간에 비례하여 갈변을 나타내는 색도의 변화가 관찰되었다 그러나, 왕겨와 미강의 전자공여능은 조사된 범위 내에서 microwave처리에 대해 큰 변화를 보이지 않았다. 활성산 소종($H_2O$$_2$,O$_2$$^{-}$, .OH)을 발생시켜 어유의 과산화에 대한 왕겨와 미강의 과산화 억제력을 조사한 결과, 전반적으로 왕겨가 미강보다 microwaye 처리에 안정함을 보였다 특히, $H_2O$$_2$에 대한 왕겨의 과산화 억제력은 미강에 비하여 매우 높게 측정되었다. 이상의 결과로 왕겨가 미강보다 항산화 물질을 많이 함유함으로써 미강보다 높고 안정한 항산화능을 나타내 고, 또한 microwave 처리로 인하여 항산화 물질이 일부 파괴되지만 항산화력을 가지는 갈변 반응 생성물이 생성되어 왕겨의 경우에는 microwave 처리에 대해 영향을 거의 받지 않 음을 알 수 있었다. 따라서, microwave 처리 공정은 왕겨나 미강의 항산화능을 이용한 가공 방법에 이용될 수 있음을 의미한다.

  • This study was conducted to investigate the effects of Ge(germanium) treatment on rice quality. Rice samples were divided into the following treatment groups: control(CON: cultivated without Ge), Ge-1(cultivated with 200 kg of rough stone powder containing 1.6 mg/kg germanium per 10 ha), and Ge-2(cultivated with 500 kg of rough stone powder containing 1.6 mg/kg germanium per 10 ha). The mean total Ge level in the Ge-2 sample was 20.47 ppb. The levels of Ca and Na in the Ge-2 rice increased by 65.12 and 110.28%, respectively, when compared to the control, whereas the Zn, Mn, Fe, Mg and K content decreased by 11.44~30.50%. No significant difference in the percentage weight of C and O was observed among samples. The order of the percentage weight of P, S, and Cl was Ge-2>Ge-1>CON. The free amino acids were higher in samples from the Ge-1 and Ge-2 groups than in samples from the control. The GABA($\gamma$-aminobutyric acid) amount in the Ge-2 products was significantly high compared to other groups. The micro structure of Ge-2 showed a firmer network than the control and had a macroporous structure. Conversely, the Ge-2 products had higher scores for stickiness, hardness and overall taste when compared to the other groups. These results suggest that rice treated with rough stone powder containing germanium can be used in the production of commercially-desired functional rice.
