  • In this study, nanofibrillated cellulose was extracted from soybean hulls - a by-product of soybeans - and compared with soybean hull nanofibrillated cellulose obtained by using other nanofibrillated methods. Dry soybean hulls were ground into prepare micrometer-sized powders, from which microcellulose was isolated using NaOH and HCl. The nanometer-sized cellulose was successfully extracted through ultrasonic dispersion and ball milling. The soybean hull nanofibrillated cellulose exhibited a diameter of 60-100 nm and a length of 0.3-1.0 ㎛, which matches the diameter of soybean nanofibrillated cellulose made by other nanofibrillated methods but is significantly shorter in length.

  • We evaluated the physicochemical and sensory properties of rice cake (Baekseolgi) admixed with various amounts of soybean peel and prepared using a microwave oven. Moisture content decreased gradually during storage but the decrease was less when soybean peel was present, compared with the control material p<0.05). Weight reduction was significantly inhibited as soybean peel level increased. The color lightness $(L^*)$ and redness $(a^*)$ values did not significantly change after addition of soybean peel. However, the yellowness $(b^*)$ value increased uponaddition of soybean peel p<0.05). The RVA properties decreased significantly with the addition of soybean peel, but pasting temperature increased. In terms of texture, neither springiness nor cohesiveness changed upon addition of soybean peel. The hardness, gumminess, and chewiness of Baekseolgi tended to decrease in proportion to the amount of soybean peel added. Adhesiveness rose gradually during storage but the increase was less when soybean peel was added, compared with control. On sensory testing, neither color nor flavor changed upon addition of soybean peel. Baekseolgi with 5% (w/w) soybean peel scored lowest in terms of taste. Hardness score and moisture level were highest when soybean peel was added to 2% or 3% (both w/w). Overall acceptability was greatest when soybean peel was added to 2% (w/w). Thus, Baekseolgi with 2% (w/w) added soybean peal was satisfactory. We conclude that addition of soybean peel to Baekseolgi prepared using a microwave oven improves physicochemical and sensory properties, and delays deterioration during storage.

  • The levels of biologically active compounds, such as isoflavone, total saponin, dietary fiber, soy oligosaccharides, and lecithin from each serving size of commercial soy products, were quantitatively determined from the raw soybean, soymilk, tofu, isolated soy protein (ISP), soybean paste(toenjang), natto, and tempeh from local and foreign market. Soy flour, natto, and soymilk contained 489.1 mg, 308.3 mg, and 138.1 mg of isoflavone in each 100 g of dry matter, respectively. The ratios of aglycone to glucoside of soybean paste and tempeh showed relatively high level compared with other tested soy products. Commercial soymilk showed the highest ratio of soluble fiber to total dietary(59%). The higher levels of dietary fiber (20.1 g) and lecithin (1.13 g) were also found in tofu. The lecithin and saponin content of isolated soy protein(ISP) were highest (0.63 g and 0.65 g/ 100 g of dry matter) among the tested samples. In conclusion, soy flour showed the highest level of biologically active compounds, such as saponin, isoflavone, dietary fiber, and soy oligosaccharides. But when the evaluation was based on the serving size, soymilk containing 31.5 mg of isoflavone, 2.59 g of dietary fiber, 0.57 g of oligosaccharides, 0.10 g of lecithin, and 0.11 g of saponin showed similarity to those of the tested soybeans(20 g).

  • The rising global demand for food and beverages with higher protein content provides manufacturers with great opportunities for innovation and premium positioning of their products as healthy choices. However, the market price volatility and supply risks associated with animal-based proteins can quickly erode margins and profitability. A diversified protein strategy that includes plant-based soy protein greatly improves your ability to predict profitability over time, while maintaining or even improving product quality.

  • 최근 대두섭취가 극히 제한되어 있는 서구사회에서 전립선암, 유방암, 골다공증과 같은 호르몬 관련 질환과 심혈관질환의 유병률이 대두식문화권 있는 아시아인에 비해 현저히 높음이 몇몇 역학연구에서 보고 되고, 대두에 함유된 이소플라본의 생리적 활성이 밝혀지면서 대두 및 이소플라본 섭취에 대한 관심이 세계적으로 높아지고 있다. 그러나 한국인의 이소플라본 섭취 수준에 관한 자료는 극히 제한되어 있다. 이에 본 연구에서는 한국인의 이소플라본 섭취 수준을 평가하고 생태학적 변인에 따른 대두/이소플라본의 섭취 수준의 차이를 비교 분석하고자 하였다.(중략)

  • Gamma irradiation was applied to soybean(Glycine max.), Hwangkeum, at dose levels of 0, 5, 10 and 20 kGy to improve the physical properties of soybeans. The time to reach a fixed moisture content was reduced depending on the increment of soaking temperatures and applied irradiation dose levels. Irradiation at 5~20 kGy resulted in reduction in soaking time of the soybeans by about 3~6 hrs at soaking temperature of $20^{\circ}C.$ The degree of cooking of soybeans in boiling water was determined by measuring the maximum cutting force of cotyledon. The cutting force to reach complete cooking was about 145g/g. Irradiation at 5~20 kGy resulted in a reduction of cooking time of soybeans by 55~75% as compared to the nonirradiated soybean. In electron microscopic observation of seed coat inner, the parenchyma of nonirradiated soybean showed tight fibrillar structure, whereas that of irradiated soybeans showed loosened and deformed structure. The microstructure of compressed cells and cotyledon epidermis was also deformed by gamma irradiation. In subcellular structure of cotyledon, the roundness of protein body was deformed and changed to spike shape at 20 kGy. Also, the size of lipid body decreased as the irradiation dose levels increased.

  • This study was conducted to investigate the effects of soybean germ of Glycin max Merrill on the improvement of lipids in the serum of cholesterol supplemented diet induced dietary hyperlipidemic rats fed for 4 weeks. The experiment diet was mixed with 0.75% cholesterol recieved a basic diet mixed with 0.75% cholesterol. No significance differences in efficency of food, liver kidney and heart. Concentration of total cholesterol and LDL cholesterol in serum was significantly lower in the methanol extracts of soybean sprout than the cholesterol supplemented diet group. In the ratio of HDL-cholesterol concentration to total cholesterol concentration, the methanol extracts of soybean sprout administration group was higher percentage than the ocher groups. Atherosclerotic index was lower in the methanol extracts of soybean sprout group than in the cholesterol group. Concentration of phospholipid in serum was more decreased in the methanol extracts of soybean sprout group than in the cholesterol diet group. From these results, the methanol extracts of soybean sprout were effective on the improvement of the lipid compositions in the serum of high fat diet induced dietary hyperlipidemic rats.
