The effects of cooking peanut kernels before grinding on the n-hexanal content of peanut milk was investigated. Analysis of headspace volatiles revealed that n-hexanal was greatly reduced by cooking peanut kernels before grinding. Total solids and protein content tended to decrease as cooking time was increased. The most satisfactory condition of cooking peanut kernels for preparing peanut milk was 10 min.

콩비린내의 원인이 되는 물질중의 하나로 알려진 hexanal을 간단하게 다른 성분들로 부터 분리할 수 있는 headspace gas chromatography 방법을 이용하여 땅콩유 제조시 마쇄전에 땅콩을 열처리 하는 것이 땅콩유의 hexanal 함량에 미치는 영향을 조사한 결과 마쇄전에 땅콩을 10분 이상 열처리 하는 것이 열처리를 하지 않는 것에 비하여 hexanal 함량을 많이 감소시키는 것을 알 수 있었다. 그리고 열처리 시간이 증가함에 따라 hexanal 함량도 감소하지만 땅콩유중의 단백질함량도 함께 감소하였다. 이상의 결과로 볼 때 콩비린내의 원인물질중의 하나인 hexanal 함량의 감소를 위하여 마쇄전에 땅콩을 열처리하는 것은 필수적이나 지나친 열처리는 단백질과 같은 중요한 영양성분을 저하시키는 것으로 판단된다.

The effect of fermentation of peanut milk with lactic acid bacteria on n-hexanal content was investigated. Changes in pH, titratable acidity and viable cell populations indicated that Streptococcus salivarius subsp. thermophilus was adapted better than Lactobacillus delbrueckii subsp. bulgaricus during fermentation. Analysis of headspace volatiles revealed that n-hexanal, which is one of the compounds responsible for undesirable green/beany flavor in peanut milk, completely disappeared as a result of fermentation. S. salivarius subsp. thermophilus was more effective than L. delbrueckii subsp,. bulgaricus in reducing the n-hexanal content. No significant difference was found in water sorption between fermented and unfermented peanut milk.

This study was carried out to investigate the physicochemical and sensory properties of milk with added powdered peanut sprout extract microcapsules (PPSEM) during the storage at $4^{\circ}C$ for 16 d. The size of PPSEM varies from 3 to $10{\mu}m$ as observed by the scanning electron microscopy (SEM). The pH values of all samples ranged from 6.8 to 6.6 during the storage. Release of resveratrol for 0.5 and 1% PPSEM addition was about $0.89{\mu}l/ml$ and TBARS value found to lower during storage of 16 d. The $a^*$ and $b^*$ color values of high concentrations (1.5, 2.0, 2.5 and 3.0%) of PPSEM-added milk samples were significantly increased during the storage (p<0.05). The sensory test revealed that the overall acceptability of PPSEM (0.5 and 1%) added milk sample were quite similar to that of control. Based on the data, it was concluded that the low concentrations of the microcapsules (0.5 and 1.0%, w/v) could be suitable to produce the microcapsule-supplemented milk without significant adverse effects on the physicochemical and sensory properties of milk.

This study was performed to identify the effect of lactic-fermentation of peanut milk on n-hexanal content. Changes in viable cell populations, pH and titratable acidity indicated that there was a synergistic interaction between Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp. thermophilus during fermentation. The analysis of headspace volatiles revealed that n-hexanal nearly disappeared due to fermentation. S. salivarius subsp. thermophilus was more effective than L. delbrueckii subsp. bulgaricus in reducing the n-hexanal content.

A study was conducted to examine the physicochemical and sensory properties of milk supplemented with nanopowdered peanut sprouts (NPPS) at different concentrations (1, 3, 5, 7, and 9%, w/v) during the storage at $4^{\circ}C$ for 16 d. The size of NPPS ranged from 300-350 nm as observed by the particle size analyzer. The pH values of all samples ranged from 6.8 to 6.6 during the storage of 16 d. In color, the $L^*$ value of milk samples were not remarkably influenced by NPPS supplementation, whereas the $b^*$ and $a^*$ values significantly increased with the NPPS supplementation at all concentrations at 0 d storage, due to the original yellow color of NPPS powder (p<0.05). DPPH study revealed that higher antioxidant activity of milk supplement with higher concentrations of NPPS. TBARS value found to lower at the lower concentrations (1 and 3%, w/v) of NPPS supplementation. The sensory test revealed that the overall acceptability scores of NPPS supplemented milk samples (1 and 3%, w/v) were quite similar to control throughout the storage period of 16 d. Based on the data obtained from the present study, it was concluded that the concentrations (1 and 3%, w/v) of NPPS could be used to produce NPPS-supplemented milk without significant adverse effects on physicochemical and sensory properties, and enhance functional components from the supplementation.

영양학적 가치와 경제적 효과를 향상시킨 땅콩요구르트를 제조하기 위하여 먼저 본 실험에 사용한 땅콩박의 일반성분을 분석한 결과는 수분 2.30%, 조단백31.39%, 조지방 38.84%, 회분 2.89% 그리고 탄수화물이 24.58%로 나타났다. 그리고 탈지분유에 땅콩박을5%, 10% 및 15%를 첨가하여 요구르트를 제조하여 그 품질의 특성을 조사한 결과는 다음과 같다. 실험구 중 5%와 10% 땅콩박으로 제조한 요구르트의 적정산도가 둘 다 1.58%로, 땅콩박 무첨가구의 적정산도 1.55%보다 약간 높은 것으로 나타났으며, 젖산균의 생육은 첨가된 땅콩박으로 촉진되어 무침가구의 8.3 log cfu/ml보다 5% 땅콩박 첨가구가 8.9 log cfu/ml로 가장 높았다. 땅콩박 요구르트의 점도는 5%에서 3,800 cps로, 무첨가구의 3,500 cps보다 높았으나 15% 땅콩박 첨가구에서는 무첨가구의 점도보다 낮은 2,533 cps로 나타났다. 5$^{\circ}C$에서 15일간의 저장시 땅콩요구르트는 pH, 총산도 및 생균수에 거의 변화가 없이 안전한 것으로 나타났다. 색도에서 명도의 L 값은 땅콩박의 첨가비율이 증가함에 따라 감소하였고 적색도 a값 은 뚜렷하게 증가하였으며 그리고 황색도의 b 값은 땅콩박 5% 첨가시 증가하였다가 10% 이상에서는 다시 감소하는 것으로 나타났다. 관능검사에서 무첨가구에 비해 땅콩박 첨가구가 모두 낮은 값을 나타내었다.

The purpose of this study was to determined the rate of sensitization to food allergen in children with Atopic Dermatitis (AD) in Korea. A total of 3,783 patients (male = 1983, female = 1800) with AD (age under 18 years) who had visited Samsung Medical Center from 1998 to 2003 were enrolled in the study. Food hypersensitivity was measured by specific IgE to egg, cow's milk, soy, peanut, wheat, buckwheat, beef, pork, chicken, shrimp, crab, salmon, mackerel, etc. Specific IgE levels > 0.7 kU/L. by Captured Allergen Product (CAP) assay were considered positive. Chi-square test at p value < 0.05 was used to examine the difference of the prevalence by sex and age. The rate of sensitization to multiple food allergens was 31.2% and decreased with age. Hypersensitivity to egg showed highest prevalence, which was 24.3%, compared to the prevalence of other foods. High prevalence of hypersensitivity to milk. wheat, soy, peanut, crab or shrimp was observed (11.6- 17.7%). Low prevalence of hypersensitivity to beef, pork, tuna or chicken was observed (1.9-3.5%). Children aged under 3 years had significantly higher prevalence of hypersensitivity to egg, milk, soy and beef than children aged at least 3 years. Our results stress the need for examination of food hypersensitivity aimed at identified and limited each food allergen among children with AD caused by food to help patients outgrow their food allergy.

땅콩유 제조시 땅콩의 침지시에 NaHCO$_3$를 첨가하는것과 분쇄전에 땅콩을 열처리하는 것이 n-hexanal 함량에 미치는 영향을 조사하기 위하여 headspace gas chromatgraphy 방법을 이용하여 조사하였다. 분쇄전에 땅콩을 열처리한 경우에는 n-hexanal함량이 현저하게 감소됨을 알 수 있었으며 열처리 시간이 증가함에 따라 n-hexanal 함량도 감소하지만 땅콩유중의 충고형분과 단백질함량도 함께 감소하였다. 이상의 결과로볼 때 콩비린내의 원인물질 중의 하나인 hexanal 함량의 감소를 위해서는 두유의 경우처럼 분쇄전에 땅콩을 열처리하는 것은 필수적이지만 지나친 열처리는 땅콩유는 단백질함량을 감소시켜 영양가가 저하시키므로 땅콩을 10분간 가열하는 것이 가장 바람직한 가공조건이라고 판단된다.

식품과민반응의 선천적 이력(natural history)과 방어의 이해는 식품 알레르기 환자의 관리에 매우 중요하다. 이러한 주제에 관하여 많은 연구내용들이 완전히 일치하지는 않지만 데이터에서 몇 가지 분명한 교훈을 얻을 수 있다. 첫째, 식품 알레르기는 매우 일반적인 것이다. 둘째, 식품 알레르기의 거의 대부분은 생후 1~2살에 시작한다. 셋째, 모든 식품 알레르기는 일반적으로 긍정적인 결과에 대한 예외가 있지만 증가하고 있는 실정이다. 넷째, 식품 알레르기는 대부분의 어린이들이 시간이 지나면서 없어지지만 일부는 호흡기 알레르기로 발달하여 종종 아토피질환의 시초가 된다. 마지막으로 적어도 몇 가지 식품 알레르기는 유아기와 어린이 시기에 주요 식품알레르겐들을 피함으로써 막을 수 있다.
