        In this study, the protein content and functional changes in soybeans cultured with Phellinus linteus HN00K9 were analyzed. P. linteus HN00K9 was cultured on soybeans. The crude protein content in soybeans cultured with HN00K9 (PMS) was 41.99%, which was higher than that in soybeans not cultured with the mushroom (UCS). The total free amino acid content in PMS increased to 39,963 mg/100 g, which was higher than that in UCS (36,817 mg/100 g). In particular, in PMS, glutamic acid accounted for 18.5% of the total amino acids at 7,413 mg/100 g. The total polyphenol content in PMS was 2.66 mg GAE/g, which was more than 45% higher than the amount in UCS (1.45 mg GAE/g). Additionally, PMS showed a DPPH radical scavenging activity of 33.3%, which was 3 times higher than that exhibited by UCS (11.5%), reflecting its high antioxidant content. Therefore, the PMS in this study has potential for use as a functional food material.

        대두 이소플라본은 갱년기 증상에 대한 유익한 효과 때문에 폐경여성들의 관심을 끌고 있다. 본 연구는 난소절제 쥐에서 대두 이소플라본인 제니스테인과 수영운동의 동시처리(Gen+SE)가 제니스테인 단독처리(Gen)와 수영운동 단독처리(SE)에 비해 비만과 간 기능 개선에 유익한 시너지 효과를 나타낼 것 인지를 조사하였다. 난소절제 쥐는 무작위로 대조군(Con), Gen, SE 및 Gen+SE으로 나누어 8주 동안 고지 방식이를 섭취하였다. 몸무게, 백색지방조직의 무게, 간 조직의 지질추적 및 혈청 속 ALT와 AST 수치를 조사한 결과, Con에 비해 Gen과 SE는 감소하였고 Gen+SE는 Gen과 SE에 비해 더 효과적으로 감소하였 다. 간 조직에서 염증성 사이토카인인 IL-6와 TNF-α 유전자의 발현은 Con에 비해 Gen과 SE 모두에서 감소하였고, Gen+SE는 Gen과 SE에 비해 더욱 감소하였다. 그러나 adiponectin 유전자의 발현은 반대의 결과가 나타났다. 간 조직에서 지방산 산화와 관련된 유전자의 발현은 Con에 비해 Gen과 SE에서 증가하 였고 Gen+SE는 Gen과 SE에 비해 더 증가하였다. 따라서 본 연구는 대두 이소플라본과 수영운동의 상호작 용은 난소절제 비만 쥐에서 비만 조절과 저하된 간 기능 개선에 매우 효과적이며, 이것은 난소절제 쥐에서 간의 지방산 산화를 촉진함으로써 발생한 것이라는 것을 제안한다.

        Physicochemical properties and storage stability of plant-based alternative meat prepared with low-fat soybean powder (LPAM) treated by supercritical-CO2 and those of full-fat soybean powder (FPAM) were compared. Ash and crude protein contents were higher in LPAM than in FRAM. Water absorption capacity and oil absorption capacity were significantly higher in LPAM than in FPAM. Water binding capacity was higher in LPAM than in FPAM during a 20 days storage period at 5℃ and pH was significantly lower in LPAM than in FPAM after a 5~10 days storage period. Hardness, gumminess and chewiness significantly increased with the increase in the storage period, and the three were significantly higher in LPAM than in FPAM after 10 days and 20 days of storage. The acid value showed no remarkable difference according to the storage period in LPAM; however, it was significantly higher in FPAM than in LPAM after 20 days of storage. The peroxide value and TBA value were significantly increased according to the storage period, and were significantly lower iin LPAM than in FPAM during all the storage periods. Therefore, the use of low-fat soybean powder may be effective in improving oxidative stability during storage in the production of plant-based alternative meat.

        The present study was conducted to examine the effect of soybean silage as a crude protein supplement for corn silage in the diet of Hanwoo steers. The first experiment was conducted to evaluate the effect of replacing corn silage with soybean silage at different levels on rumen fermentation characteristics in vitro. Commercially-purchased corn silage was replaced with 0, 4, 8, or 12% of soybean silage. Half gram of the substrate was added to 50 mL of buffer and rumen fluid from Hanwoo cows, and then incubated at 39°C for 0, 3, 6, 12, 24, and 48 h. At 24 h, the pH of the control (corn silage only) was lower (p<0.05) than that of soybeansupplemented silages, and the pH numerically increased along with increasing proportions of soybean silage. Other rumen parameters, including gas production, ammonia nitrogen, and total volatile fatty acids, were variable. However, they tended to increase with increasing proportions of soybean silage. In the second experiment, 60 Hanwoo steers were allocated to one of three dietary treatments, namely, CON (concentrate with Italian ryegrass), CS (concentrate with corn silage), CS4% (concentrate with corn silage and 4% of soybean silage). Animals were offered experimental diets for 110 days during the growing period and then finished with typified beef diets that were commercially available to evaluate the effect of soybean silage on animal performance and meat quality. With the soybean silage, the weight gain and feed efficiency of the animal were more significant than those of the other treatments during the growing period (p<0.05). However, the dietary treatments had little effect on meat quality except for meat color. In conclusion, corn silage mixed with soybean silage even at a lower level provided a greater ruminal environment and animal performances, particularly with increased carcass weight and feed efficiency during growing period.

        This study was performed to investigate the antioxidant and antidiabetic activities of soybean fermented with Monascus. Also, the changes in the content of isoflavones and Monacolin K were analyzed. It was observed that the glycoside forms of daidzin and genistin were converted to aglycones of daidzein and genistein within 6 days of fermentation. The product can be used as a health functional material that can increase bioavailability. Monacolin K production was found to increase significantly with the progression of fermentation with an increase to 0.04 mg/g and 0.44 mg/g on 6 and 12 days of fermentation, respectively. The DPPH radical scavenging activity of soybean fermented with Monascus was significantly increased compared to that of soybean. The protein expression of inflammation-related genes (TNF-α, IL-6, and COX-2) in the MIN cell was significantly increased in the presence of alloxan compared to the normal group, but a decrease was observed in the presence of soybean fermented with Monascus. In conclusion, soybean fermented with Monascus showed the highest antidiabetic and antioxidant effects. These results suggest that soybean fermented with Monascus has the potential to be used as a beneficial ingredient with antidiabetic and antioxidant effects.

        In this study, chemical information on a total of 20 individual compounds was constructed to identify isoflavones from the previous reports related with used parts(seeds, leaves, stems, pods) and products of soybean(Glycine max L.). Through constructed library and UPLC-DAD-QToF/MS analysis, a total of 19 individual isoflavones including aglycones, glucosides, acetylglucosides and malonylglucosides as major compounds was identified and quantified from 14 selected soybean seeds. Among them, genistein 7-O-(2"-O-apiosyl)glucoside and genistein 7-O-(6"-O-apiosyl)glucoside(ambocin) were identified tentatively as novel compounds in soybean seeds. Besides, among malonylglucosides, glycitein 4'-O-(6''-O-malonyl)glucoside was estimated for the first time. Total isoflavone contents were distributed from 240.21 to 445.21(mg/100 g, dry matter) and 7-O-6''-O-malonylglucosides were composed of 77.8% on total isoflavone as well as genistein derivatives were confirmed as major class. It was considered importantly that the development of isoflavone-rich varieties was necessary to strengthen their effects such as anti-inflammation, anti-cancer and menopause mitigation. The qualitative and quantitative data presented precisely in this study could be help to select and breed isoflavone-rich varieties. Furthermore, their basic isoflavone profile is expected to be applied to estimate the change of isoflavone conjugates on bioavailability after soy food supplements.

        This study investigated the substitution effect of phosphate and isolated soybean powder (ISP) by Allomyrina dichotoma larvae powder (AP) in emulsion sausage. The sausages were prepared for five treatments: 1) positive control (PC): sausages manufactured with sodium pyrophosphate (0.3%) and ISP (1%); 2) negative control (NC): sausages manufactured without sodium pyrophosphate, and ISP; 3) phosphate replacement (PR): sausages manufactured with ISP and AP (1%); 4) ISP replacement (IR): sausages manufactured with sodium pyrophosphate and AP; 5) phosphate and ISP replacement (PIR): sausages manufactured with AP. The 1% AP extract showed DPPH radical scavenging (45.65±2.468%) and metal chelating (22.46±3.559%) activity. The high pH value of AP (8.03) increased the pH of the meat batter of PR, IR, and PIR (p<0.05), but there was no inhibitory effect on cooking loss. Cooking loss of IR was not significantly different with PC due to phosphate. The addition of AP decreased the L* and a* values and increased the b* values, and decreased hardness, chewiness, and springiness of PR, IR, and PIR (p<0.05). AP did not inhibit lipid oxidation in sausages, in contrast to phosphate. In sensory evaluation, the addition of AP resulted in low scores for all sensory parameters of the sausages, although most panels had normal or positive awareness (p<0.05). Aroma was more influential on samples than color. Overall, AP did not replace phosphate and ISP in the sausages. Therefore, processes such as eliminating unique aroma and color and increasing solubility through particle size control are necessary to use AP as a protein source.

        The purpose of this study was to develop a functional senior mixed soymilk for seniors and to provide functional senior-mixed soymilk to prevent disease outbreaks. The isoflavone content of senior soymilk was 0.15±0.01 mg/g. The β-glucan content of senior soymilk was 9.82±0.01 mg/g. The weight gain of mice were significantly higher in the high-fat diet group than in the other groups. The serum triglyceride content was high at 102.67±40.61 mg/dL in the high-fat diet group, but significantly lower at 83.00±42.43 mg/dL in the 20% senior soymilk group. Thus, the results of this study comprehensively suggest that food intake should be ingested for each life cycle with reference to the dietary reference intakes for Koreans. In particular, the elderly in their 50s and older are deficient in protein and weakened immune capacity, so it is imperative that they maintain their health through various foods such as soymilk, which is evenly nutritious.

        To increase the functional material content of soybean, a repetitive steaming and drying process was used. We investigated the changes in the total polyphenol content, the antioxidant activity, and the angiotensin-Ⅰ converting enzyme (ACE) inhibition in soybean following nine rounds of steaming and drying. Soybean was steamed 9 times for 2 h and then dried 9 times from 55℃ to 73℃ for 3 h. The total polyphenol content in the soybean reached a maximum value of 60.47 mg GAE eq./100 g at 73℃ while the total polyphenol content in the raw soybean reached 25.17 mg GAE eq./100 g. In the raw soybean samples, the DPPH radical scavenging activity (5 mg/mL) was 8.04% but it increased by 43.29% after drying 9 times to 73℃. ABTS radical scavenging activity also improved following 9 rounds of steaming and drying. ACE inhibitory activity of the soybean dried 9 times at 73℃ was 58.94% at 10 mg/mL. These results showed that steaming and drying soybean 9 times enhanced the antioxidant activity and the ACE inhibitory activity of soybean. Therefore, more research on the biological and anti-hypertensive activity of soybean using this steaming and drying method is necessary.

        The purpose of this study was to investigate the quality of dehulled soybean (DHSB), and the rapid preparation possibility of soybean milk with DHSB (SM-DHSB), and then the quality of SM-DHSB. In DHSB, the moisture content decreased, the crude protein, crude fat, minerals, and carbohydrate contents increased, and the isoflavone (daidzein, genistein and glycitein) content was similar to that of soybean (SB). The water absorption rate of DHSB for soybean milk preparation was higher than that of SB. In the results of SM-DHSB and soybean milk (SM) qualities, the crude protein content, total solid content, and the viscosity of SM-DHSB were higher, the yield and the proximate composition (except crude protein) were similar, and the Biji production rate, and total dietary fiber content of SM-DHSB were lower compared to the SM. In terms of the isoflavone contents of SM-DHSB, daidzein and genistein content were similar, and glycitein content was lower compared with the SM. Consequently, these results suggest the possible use of DHSB for rapid SM-DHSB preparation, because the soaking time was decreased by the high water absorption rate of DHSB in the SM preparation, and the quality of SM-DHSB improved compared to those of the SM.

        Recently, health concerns related to NaCl overconsumption have led to an increased demand for sodium-reduced foods. The purpose of this research is to investigate the possibility of using enzymatically hydrolyzed isolated soybean protein (eHISP) to reduce the level of salt in salad dressing. The intensity of the salty taste enhancing effect was 31%, 29%, 43%, and 52% in the samples with 0.1%, 0.5%, 1.0%, and 1.5% eHISP added, respectively. There are significant differences between the control and samples (p<0.05). The overall acceptability was increased as the amount of added eHISP was increased when eHISP was 1.0%. However, it was lower when 1.5% eHISP was added. The pH of salad dressing was increased as the eHISP addition was increased. The results showed that the addition of eHISP to a salad dressing significantly enhances its salty taste effect.

        The aim of this study is to investigate the relationship between the sensory characteristics and protein concentration of enzymatically hydrolyzed isolated soy protein. As a result of QDA, 34 attribute descriptors were developed. According to the results of the flavor profile, the strengths of most color and tastes except sourness were evaluated before activated carbon treatment sample. Principal component analysis (PCA) was performed to summarize the relationship between attributes and samples. The result of PCA was 56.35% (F1) and 35.05% (F2), having explained 94.13% in total variablility. In case of the untreated sample of active carbon, it was located in the first quadrant and correlated with color, flavor, a slightly salty taste, and a slightly bitter taste. It also showed high correlation with meju taste. The activated carbon treatment samples were located in the second quadrant and correlated with delicate taste, slight saltiness, sourness, and umami, having high correlation with burned rice.
