  • The objective of this study was to investigate the sensory and quality characteristics of Solsulgi containing different ratios of ingredients such as pine leaves power(1, 2, and 3%), sugar, and water. The results of sensory evaluation showed that Solsulgi containing 1% pine leaves powder had the higher scores in overall acceptability, color and flavor preference. In the textural analysis of Solsulgi, the springiness, chewiness, gumminess, and hardness were decreased by adding pine leaves powder. The hunter's color L value of Solsulgi was decreased by the increase of pine leaves powder. The more pine leaves powder was added, the redness and yellowness of Solsulgi were increased. The moisture content of Solsulgi was higher in the samples with 3% pine leaves powder than those with 1 %.

  • Two experiments were designed and executed to measure the effectiveness of the two-fluid fogging system in controlling whiteflies in tomato cultivation. The two-fluid fogging system that lowers temperature and raises humidity in greenhouses provides an eco-friendly method of preventing damages from whiteflies. The first experiment elucidated the effect of fogging treatment on the elimination of whiteflies and investigated the sectional distribution of whiteflies. The second experiment analyzed the vertical distribution, the motility of whiteflies and reduction of the number of whiteflies under the fogging system. The result of the experiments showed that the fogging system lowered the number of whiteflies and decreased their motility significantly. It affected the vertical distribution of whiteflies as well. Based on these experiments, we strongly recommend using the fogging system to prevent and control whiteflies in greenhouses, in addition to installing yellow sticky traps in the areas that have the highest density of whiteflies.

  • Baekseolgi made with arrowroot flour (AF, 0 to 15% of rice flour) was steamed to examine the effect of heating on its antioxidant activity and physicochemical properties. Despite the presence of abundant dietary fiber and superior water-holding capacity of AF, moisture in baekseolgi was not significantly increased. This could partly be attributed to AF having 50% less moisture content than rice flour. Hence, hardness of baekseolgi was also not significantly altered. Total reducing capacity and flavonoid content of baekseolgi increased proportionally with the increase in AF addition. However, these values were lower than the predicted values calculated from the antioxidant activities of heated AF, which was more apparent in total reducing capacity. This indicated that the stability of non-phenolic reducing compounds in AF was lower than that of the phenolic compounds. Thermally processed baekseolgi made with 9% AF exhibited antioxidant activity without noticeable loss in the quality of the product.

  • 본 연구는 유색미 가루와 전분의 이화학적 특성 및 호화특성을 알아보기 위하여 수행되었다. 유색미 가루와 전분의 일반성분, 가루의 식이섬유 함량 및 보수력을 분석하였다. 주사전자현미경을 이용하여 가루와 전분의 형태를 관찰하였다. 유색미 전분의 청가 및 아밀로오스 함량을 측정하였고, 가루와 전분의 물결합 능력, 팽윤력과 용해도를 조사하였으며, RVA에 의하여 호화특성을 조사하였다. 유색미 가루의 일반성분은 수분 13.5%, 조단백질 9.1%, 조지방 2.2%, 회분 1.4%, 조섬유 1.3%이었고, 전분의 경우는 수분 13.6%, 조단백질 0.45%, 조지방 0.11%. 회분 0.12%이었다. 백미나 현미에 비하여 단백질의 함량이 매우 높았으며. 조지방과 회분, 조섬유의 함량은 백미에 비하여는 휠씬 높았고, 현미와는 비숫한 수준이었다. 유색미의 식이섬유 함량은 불용성 식이섬유가 3.3% 수용성 식이섬유 2.4%로 총 7.7%였다. 분리된 불용성 식이섬유의 보수력은 약 7.12(g $H_2O$/g NDF)로 매우 물자의 친화력이 큰 편이었다. 주사전자현미경에 의한 관찰결과 가루의 경우는 전분 주위에 단백질 등의 다른 성분들이 있는 것을 볼 수 있었으며, 전분은 다른 쌀 전분과 마찬가지로 불규칙한 다각형의 형태였으며, 크기는 대부분 2-5$\mu\textrm{m}$의 범위로 비교적 균일하였다. 유색미 전분의 청가는 전분이 0.11, 아밀로오스가 0.82. 아밀로펙틴이 0.07이었으며, 아밀로오스 함량은 16.8%이었다. 물결합 능력은 가루가 248%, 전분이 146%이었다. 팽화력과 용해도는 가루와 전분 모두 7$0^{\circ}C$ 이후 증가하였으며 전분이 가루보다 더 급격히 증가하였다. RVA에 의한 호화양상에서 가루와 전분의 호화온도는 각각 85.7$^{\circ}C$와 66.2$^{\circ}C$로 나타났다. 최고점도는 가루가 127.7 RVU, 전분이 243.3 RVU로 차이가 컸으나. setback 후의 점도는 176 RVU과 187.7 RVU로 큰 차이가 없었다. 호화액의 consistency는 가루와 전분이 각각 92와 94로 비슷하였다.

  • Effects of silkworm powder addition on rheological properties of dough and quality characteristics of bread were investigated. Protein content of silkworm powder was 53,98%, much higher than 12.46% of wheat powder, Crude fiber, fat, and pretense contents of silkworm powder were higher than those of wheat flour, Acid analysis revealed glutamic acid content was highest 4,046.16 mg thus, significant depreciation of breadmaking was expected due to weakened gluten structure or dough. Addition of silkworm powder(optimum at 2%) with pretense inactivated by heat treatment resulted in significant improvement of volume and bread quality, with external and internal scores close to those of the control.

  • In an attempt to develop composite flours based on raw materials available in Korea, six domestic resources were investigated with respect to their physical and chemical properties, nutritive value and economy. The results are summarized as follows: 1) Flours from naked barley, sweet potato, potato, corn, defatted rice bran and defatted soybean were compared in respect of their proximate composition, thiamine content and protein score. 2) In color comparison, naked barley and defatted soy flours were comparable to wheat flour whereas corn and sweet potato flours were a little inferior. In raising power, naked barley and defatted soy flours were similar to wheat flour and others were inferior. 3) In maximum viscosity of flours by amylograph, naked barley, corn and potato flours were higher than wheat flour and others were lower. In viscosity in cooling, corn flour was similar to wheat flour and naked barley and potato flours were lower. Addition of $10{\sim}20%$ defatted soy flour into other flours generally caused the lowering of viscosity. Addition of emulsifiers such as glyceryl monostearate, calcium stearyl lactylate, Methocel and Emulthin into the flours manifested different effects on the amylogram. 4) In nutritional test by rat, diets consisting of naked barley, sweet potato, potato or corn flours, each containing defatted soy flour (at 10% level with exception of 20% for sweet potato flour) and naked barley flour fortified with lysine were similar to wheat flour in digestibility, but were superior in NPU and biological value. 5) In price estimation, sweet potato and corn flours were competitive with wheat flour, but naked barley flour was a little expensive. On the other hand, barley and sweet potato are promising in terms of domestic production.

  • A potent mold strain was selected to digest raw starch, which was classified as a strain of Rhizopus of zoe. Its amylase production was maximized when grown on wheatbran media for 3 days at 3$0^{\circ}C$ and initial pH 4. The crude enzyme was tested for ethanol fermentation by yeast, Saccharomyces cerevisiae IFO 7026, on various starchymaterials and the ethanol production after 4 days was: 9.4% from rice powder, 9% from corn powder, 8.1% from sweet potato powder, and 5.4% from potato powder, respectively.
