  • The functional properties of sesame protein concentrate(SPC) using different size of ultrafiltration(UF) membranes were examined and compared with those of conventional acid-precipitated sesame protein concentrate. The protein contents of SPC by UF with molecular size of 10K, 30K and look dalton membranes were 84.2%, 82.7%, and 76.4%, respectively, and that of acid-precipitated SPC was 88.7%. The nitrogen solubility of SPC by UF was higher than that of conventional SPC at various pH levels. Especially, it showed three-fold increase at near isoelectric point. However, water absorption capacity and fat absorption capacity of SPC by UF were decreased. For emulsion and foam properties, there were no significant differences between SPC by acid precipitation and SPC by UF method. At various pH levels, SPC by membrane with pore size of 30K dalton showed the highest emulsion properties. The SPC by UF had slightly higher viscosity than defatted sesame flour and SPC by acid precipitation.

  • This study was carried out to investigate the effect of hydrolysis by proteolytic enzymes on the functional properties of sesame protein concentrate. Sesame protein concentrate was hydrolyzed with papain, pepsin and trypsin to obtain 10% and 20% degree of hydrolysis. The nirogen solubility in water was increased with increasing the degree of hydrolysis. Bulk density was increased by enzymatic hydrolysis but water absorption capacity was increased only in the case of pepsin-hydrolyzed SPC. Higher fat absorption capacity was found in SPC with 10% DH than SPC with 20% DH. Emulsifying activity was also increased by enzymatic hydrolysis except SPC with 10% DH by papain.

  • This study was attempted to determine the effect of reduction of phytate and phenol compound on the functional properties of sesame protein concentrate. The concentrates were prepared by using dist-water, HCI and butanol. The content of phytate and phenol compound in defatted sesame meal were 4.55% and 3.42% respectively. Considerable amount of phytate was reduced by using HCI, and butanol was effective in removing phenol compounds, Higher bulk density and fat absorption were found in sesame protein concentrate prepared by butanol but higher water absorption was found in the concentrate prepared by dist-water. Also, emulsifying and foaming properties were improved by butanol treatment.

  • Sodium hexametaphosphate(SHMP)가 탈지대두박 단백질의 추출과 농축단백질의 색도 및 아미노산 조성에 미치는 영향을 검토하였다. SHMP에 의한 단백질의 추출은 1.5% SHMP에서 가장 높았으며 이 이상의 농도에서는 오히려 감소하는 결과를 나타내었다. 또한 참깨박 단백질의 추출은 pH 5.0에서 17.0%, pH 2.0에서는 22.7%로 아주 낮았으나 pH 12.0에서 60.7%의 단백질이 추출되었다. 시료와 용매와의 비율에 있어서는 1 : 40에서 약 60%의 단백질이 추출되었으며 비율이 증가할수록 추출율이 증가하는 경향을 나타내었고 SHMP처리로 인해 농축단백질의 색도가 개선되었다. 참깨빡 농축단백질의 아미노산 조성을 비교한 결과 SHMP의 처리에 의해 lysine과 hethionine의 함량이 현저히 감소된 반면 valine과 leucine함량은 증가된 결과를 나타내었다.

  • Defatted sesame flour is the by-products obtained after oil extracting process. Although this flour has high quality and quantity of protein its use is limited only for animal feed and fertilization. Sesame seeds contain antinutrients such as oxalate, phytate and phenol compounds and these compounds lower their nutritive value. recently, ultrafiltration(UF) has been used to concentrate protein from various food sources. This study was carried out to examine the effects of UF with different membrane pore size on the components of sesame protein concentrates including antinutrients and to compare with that of conventional acid-precipitated sesame protein isolate. The protein contents of sesame protein concentrates prepared by JF using 10K, 30K, 100K were 84.2%, 82.7%, 76.4% and the protein yields were 36.44%, 34.69, 31.43% and the protein contents was 88.7% Alkali extraction process at pH 9.0 followed by UF technique reduced oxalate and phytate content. There were 85% and 94% reduction of oxalate and phytate content by UF with membrane pore size of 100K daltons, respectively. However, the content of total phenol compounds was not reduced by this method. About 99% of calcium and 50% of zinc were removed by UF with membrane of 100K daltons. total essential amino acid contents of sesame protein concentrates prepared by UF were decreased slightly when compared with acid-precipitated sesame protein concentrate.

  • Sesame protein concentrate(SPC) was prepared from defatted sesame flour(DSF) at several different pH(2.0, 7.0, 9.0, 11.0) for protein extraction. Some of their functional properties were determined in order to compare the effects of pH during preparation of concentrates. Compared with DSF, nitrogen solubility was markedly improved in all SPC, and SPC extracted at pH 11.0 showed the highest solubility at all pH leaves examined. Fatabsorption was increased in all SPC prepared, but water absorption was decreased as the extraction pH of protein increased. The emulsifying properteis and foaming properties of SPC were remarkably higher than DSF. As the extraction pH of protein was increased, the emulsion activity was also increased, but emulsion stability was decreased. SPC extracted at pH 7.0 showed the highest foaming capacity on the other hand, the highest foaming stability was shown in SPC extracted at pH 2.0. As the protein extraction pH increased, the viscosity of the protein solution was increased. SPC extracted at pH 11.0 showed highest viscosity at all protein concentrations tested.

  • 본 연구는 참깨 단백질을 새로운 식품 단백질자원으로 이용하기 위한 목적으로 여러 pH조건에 따라 제조된 참깨 농축단백질의 성분을 비교.검토하였다. pH 2.0, 7.0, 9.0, 11.0에서 각각 추출된 농축단백질의 단백질 함량은 60.57, 67.72, 79.50, 83.44%로 추출 pH가 증가함에 따라 높은 단백정 함량을 나타내었다. 단백질의 추출은 phytate 항량을 상당량 제거시켰으며, 특히 phytate의 용해도가 낮은 pH 11 .0에서 추출된 농축단백질의 phytate 함량은 0.22%로 94.8%의 가장 높은 제거율을 나타내었다. 그러나 pH 2.0에서 추출한 농축단백질의 phytate 함량은 탈지 참깨분말과 비슷한 수준을 나타내었다. 모든 시료에서 가장 않은 양이 검출된 무기질은 칼슘이었다. 농축단백질의 무기질 함양을 보면 Ca, Mg, Zn, Fe의 함량은 pH 2.0에서 추출한 농축단백질에서 가장 높은 반면 Cu는 pH 11.0에서 추출한 농축 단백질에 가장 많이 함유되어 있었다. Na 함량은 모든 농축단백질에서 비슷한 수준을 보였고, Cd과 Pb은 검출되지 않았다. 참깨 농축단백질의 색도는 탈지 참깨 분말에 비해 약간 짙은 경향을 보였으며, 중성 (pH 7.0) 에서 추출한 농축단백질의 색도가 가장 밝게 나타났으며, 추출 pH가 낮은 단백질 일수록 밝은 색을 나타내었다.

  • Eighteen Holstein Friesian ${\times}$ Native heifers with an average live weight of $175.4{\pm}27.8kg$ were allotted to 3 dietary groups. All animals were kept individually in a stanchion barn with free access to water and urea-treated rice straw (UTS). The supplemented feeds were as follows: Group (Gr) 1 - concentrate mixture (15% CP) at 1% body weight (BW), Gr 2 - concentrate mixture at 0.7% BW + free licking of multinutrient block (MNB), Gr 3 - as Gr 2 + 0.3% BW ground com. Multinutrient block composed of 20% mineral mixture, 10% urea, 18% molasses, 20% soybean meal, 22% sesame meal, 10% cement, 0.15 million IU and 50 IU/kg MNB of vitamin A and E. The experimental period lasted 12 weeks. The result revealed that MNB enhanced intake of UTS and total dry matter intake. Animals in Gr 3 consumed a higher amount of feed than the other 2 groups, thus resulting in the highest live weight gain and tended to possess the best feed conversion ratio. Heifers in Gr 2 also performed better than Gr 1 although the difference was not significant. Average MNB intake found to be 0.65 kg/day. Feed cost per kg gain was not significantly different amon groups. However if the cost of MNB could be lower, it would benefit the production cost of animals. The advantage of MNB is the safety of using a high level of urea. Although it was supplemented to UTS which also contained non-protein nitrogen (NPN), no toxic sign was shown. The results indicated that MNB could be partially substituted to concentrate mixture and it was even better when used incombination with soluble carbohydrate feed.
