  • Korean-style fermented soybean paste (KFSP), Doenjang, is a traditional food that is consumed as a protein source in Korea. Recently, efforts to identify biolgocial response modifiers (BRMs) have been focused on food products. Accordingly, this study which isolated abiologically active substance form KFSP, named KFSP-BRM, ws defined to be aheat-stable carbohydrate with a molecular weight of 2,000 kDa. The biological activity of KFSP-BRM was not inactivated by treatment with an anti-LPS antibody. The oral as well as intraperitoneal treatment of mice with KFSP-BRM significantly enhanced the number of B cells expressing surface significantly enhanced the number of B cells expressing surface immunoglobulins (IgM and IgG). Subsequently, an increased level of immunoglobulins in the sera was also observed. In vitro. KFSP-BRM was found to upregulate the production of interleukin-1 (IL-1) and IL-6 by mactro phages and B cells but not the production of IL-2 by T cells. In conclusion, these data demonstrate the presence of a BRM in KFSP, which may provide an additional benefit to those consuming it is a food. KFSP-BRM is a novel B cellmitogen distinct from fresh soybean lectin or B cell mitogens, such as LPS and Streptococcus protein A. The major biological effects of KFSP-BRM would appear to be anincreased production of IL-1 and IL-6 by macrophages and B cells, thereby enhancing the function of mature B cells.

  • Starch characteristics and pasting properties of Tongil-type rice varieties with different amylose content were analyzed. Three different Tongil-type rice varieties and one Japonica-type rice variety were examined for their properties. Tongil-type rice varieties have longer panicles and higher rice yield (721-765 kg per 10a) than Boramchan, a Japonica-type high-yield rice variety. The protein content of the Tongil-type rice variety was higher than that of Boramchan. Japonica-type rice varieties had lower amylose content than Japonica-type rice varieties, except for Amimyeon (Milyang355). Amimyeon had higher protein content than the other varieties, and its amylose content was particularly high at 39.2%. The distribution of starch granule sizes of the four varieties was similar, and the particle size corresponding to D50 was approximately 87.8-81.9 ㎛. The pasting properties of rice flour varied among varieties. The Dasanbyeo and Hanarum2 amylogram patterns were similar. These two varieties had a higher peak viscosity (PV) and lower setback (SB) than Boramchan. In the case of Amimyeon, the hot paste viscosity (HPV), cool paste viscosity (CPV), and SB were significantly higher than those of the other Toingil-type varieties, and the breakdown (BD) was very low, showing pasting properties significantly different from that of the other varieties. The onset (To), peak (Tp), and conclusion temperature (Tc) of gelatinization of rice flour from Amimyeon were lower than those of the other tested varieties. In addition, the gelatinization temperature, measured using differnetial scanning calorimetry (DSC), and BD, measured using al rapid visco analyzer (RVA) were low in Amimyeon. Amylose content showed a high positive correlation with pasting time (PTi), HPV, and SB and a negative correlation with PV and BD.

  • The number of elderly in care facilities is increasing in parallel with a rapid increase in the elderly population in Korea. We analyzed the meal satisfaction ratings, food preferences, and nutritional intakes of 74 patients aged ≥65 years living in a nursing hospital in Daegu. Food preferences were high for cooked rice, rice gruel, meat soup, soybean paste stew, beef, frozen pollack, squid, egg, spinach, sea mustard, cabbage kimchi, apple, peanut, drinking yogurt, pickled perilla leaves, and salted squid. Preferences for duck (P<0.01) and vegetable (P<0.01) cooking method were significantly different for men and women, and preference for soybean paste stew increased with age (P<0.05). Regarding nutrient intakes, men had higher energy (P<0.01), carbohydrates (P<0.05), and zinc (P<0.05) intakes than women, while women had higher vitamin C (P<0.05) intake than men. Furthermore, energy (P<0.001), carbohydrates (P<0.001), protein (P<0.05), dietary fiber (P<0.01), vitamin B6 (P<0.01), phosphorus (P<0.05), and zinc (P<0.001) intakes significantly decreased with age. Men had a significantly higher nutrient adequacy ratios (NARs) for carbohydrates (P<0.05) and cal- cium (P<0.01) than women, while women had a significantly higher NARs for protein (P<0.05), vitamin A (P<0.01), vitamin C (P<0.05), thiamine (P<0.01), riboflavin (P<0.001), iron (P<0.001), and zinc (P<0.01). Mean adequacy ratios were 0.69 for men and 0.75 for women. In particular, NARs for carbohydrates (P<0.01), vitamin B6 (P<0.01), and calcium (P<0.05) decreased significantly with age. In summary, the study shows that supplementing vitamin C, vitamin B6, calcium, and iron, reducing sodium, and providing meals that reflect preferences will improve the nutritional statuses of elderly residents in a nursing hospital.

  • In a previous study, a biological response modifier (BRM) specifically enhancing the function of B-cells was isolated from Korean fermented soybean paste (Kfsp), but not from non-fermented soybeans. In this study, we attempted to isolate the bacteria producing the BRM from Kfsp (KfspBRM) by ELISA using anti-KfspBRM and by B-cell proliferation. Five bacteria whose culture supernatants showed the BRM activities were isolated, and one of them was identified as Bacillus licheniformis E1. The bacterial BRM (bBRM) originated from a slime layer of B. licheniformis El had a molecular weight of 1,594 kDa, and contained $33\%\;(w/w)$ of reduced sugar and $4.6\%\;(w/w)$ of protein content. The bBRM appeared to be a glycoprotein that is physically, structurally, and functionally similar to the KfspBRM, suggesting that the isolates including B. licheniformis El may produce the KfspBRM in the fermentation process of soybean paste. The mass production of the BRM by the bacterium may help to study B-cells in immunology, and the enrichment of the BRM in Kfsp may help patients in future who are medically in need of potentiation of B-cell proliferation and antibody production.
