The objective of this study was to investigate the effects of combinations of tofu paste and non-starch polysaccharides (NSP) on the oil uptake reduction (OTR) of deep-fat fried cake doughnuts. OTR agents were tofu paste (from grinding tofu with deionized water, followed by passage through a 60 mesh sieve), and five neutral and nine anionic NSPs. A control doughnut (without tofu paste or NSP), tofu doughnut (with tofu paste) and NSP-tofu doughnut (with tofu paste and NSP) were prepared. The moisture and total lipid (TL) content, cross-section image, color characteristic, and specific volume were measured. The tofu and NSP-tofu doughnuts exhibited higher moisture and lower TL content than the control. OTR was 10.8% for the tofu doughnut, and between 13.2% and 41.2% for the NSP-tofu doughnut. The highest OTR (41.2%) was found in the NSP-tofu doughnut with a combination of tofu paste and sodium alginate (NaA). The specific volume of the NSP-tofu doughnuts with combinations of tofu paste with NaA (2.5 mL/g), locust bean gum (2.5 mL/g), and κ-carrageenan (2.4 mL/g) was very close to that of the control (2.6 mL/g). Considering the OTR and specific volume of doughnuts, the combination of tofu paste and NaA would be most effective in reducing the oil uptake of doughnuts during deep-fat frying.

Soybean cultivar ‘Seonpung’ was developed for soy-paste and tofu. Suwon 224 and YS1325-3S-2 were crossed in 2003 and selected from F3 to F5 by pedigree method. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2009 to 2010, and regional yield trial (RYT) in twelve regions was conducted from 2011 to 2013. In RYT, ‘Seonpung’ was stable in variable environments and a high yield cultivar. ‘Seonpung’ is determinate, white flower, yellow spherical seed and yellow hilum. Flowering date and maturity date were Aug. 5 and Oct. 19, respectively. Plant height was similar to ‘Daewonkong (standard cultivar)’. However ‘Seonpung’ has higher node number (16) and seed weight (25.9g/100-seed weight) than ‘Daewonkong’ (14 and 24.2g/100-seed weight). ‘Seonpung’ is resistant to root rot, and it also has high level of resistance to bacterial pustule and soybean mosaic virus. The yield of tofu of ‘Seonpung’ was 241%, and noticeably lighter, and solidity was higher than ‘Daewonkong’. Soybean malt scent, fermented soybean yield and γ-polyglutamic acid (γ-PGA) of ‘Seonpung’ were 4, 181% and 31.7㎎/g. The yield in adaptable regions was 340kg/10a (21% increase compared to ‘Daewonkong’). ‘Seonpung’ is expected to be cultivated and used widely for soy-paste and tofu. (Registration number: 5931)

‘청아’는 내재해 다수성 장류용콩 신품종을 육성하기 위하 여 내도복, 다수성 품종인 ‘신팔당콩 2호’를 모본으로 1999년 도에 인공교배한 SS99505 조합으로 계통육성법으로 선발하였으며 계통명은 ‘강원 110호’이다. 꽃색은 백색이고 잎모양 은 난형이며, 종자모양은 구형이다. 종피색과 배꼽색은 황색 이고 백립중은 25.2 g으로 ‘태광’보다 2.4 g 무거운 대립이다. ‘태광’에 비하여 개화기는 7월 20일로 11일 빠르고 성숙기는 9월 30일로 5일 빨라 조숙종이면서도 등숙기간은 6일 길다. 특히, 도복에 강하며 불마름병과 바이러스에 강하다. 수량성 은 ‘태광’보다 생산력검정시험에서는 15% 증수하였고, 철원 등 4개 단작지역 적응성검정시험에서는 14% 증수하여 평균 종실수량이 ha당 2.72톤이다.

‘호반’은 대립이며 종자 특성이 우수한 GWS91을 모본으로 하고 Lipoxygenase 2와 3이 결핍된 ‘진품콩’을 부본으로1995년도에 인공교배를 하고 1996년부터 1997년까지 F1-F2양성하였다. 1998년부터 2003년도에 F3 이후 세대를 전개하며 계통육종법으로 선발한 GSL95102-2B-16-5-1-1계통으로계통명은 ‘강원5호’이다. ‘호반’의 주요특성으로는 유한신육형이며 꽃색은 자색이고 엽형은 난형이다. 입형은 편구형이고종피색은 황색, 제색은 황색이며 100립중은 29.0 g으로 대립이다. 개화기는 7월 23일, 성숙기는 10월 5일로 ‘진품콩 2호’와 유사한 중만생종이다. 종실 성분중 조단백함량은 39.0%로‘진품콩 2호’와 유사하였고, 조지방 함량은 18.5%로 다소 높았다. 기능성 성분중 아이소플라본 함량이 1,995 ㎍/g 로‘진품콩 2호’보다 25% 높았으며, 콩 비린내 유발 효소인 Lipoxygenase 2가 결핍되었다. 조단백 함량은 ‘진품콩 2호’와 유사하였으나, 조지방 함량은 다소 높았고, 메주와 청국장가공 시 발효정도와 풍미가 ‘진품콩 2호’보다 양호하였으며,청국장 수율도 높았다. 수량성은 2004년부터 2006년까지 3년간 실시한 지역적응시험결과 단작지에서 2.69 MT/ha로‘진품콩 2호’ 2.62 MT/ha 대비 3% 증수하였고, 이모작지에서는 2.60 MT/ha로 ‘진품콩 2호’ 2.59 MT/ha와 차이가 없었다.
