The aim of this study was to investigate the changes in identification markers of irradiated foods after treatment of the full-overlapped gravitational field energy (FGFE). Wheat and soybean samples were irradiated at 0-5 kGy of Co-60 gamma energy, and analyzed for photostimulated and thermo luminescence characteristics (PSL and TL) and sprouting rate at 0 and 6th month after FGFE treatment. As a screening method for irradiated samples, PSL photon counts (PCs) for the non-irradiated samples appeared negative (<700 PCs), while irradiated samples gave positive (>5,000 PCs). But FGFE-treated irradiated samples appeared intermediate (700-5,000 PCs), showing decreased PCs during storage. The TL analysis on irradiated samples exhibited glow curve peaks in range of 150-200℃ and TL ratio (TL1/TL2) was also >0.1. Therefore, identification of irradiated samples was possible using thermoluminescence. But the glow curve range of FGFE-treated irradiated samples shifted from 150-200℃ to 180-230℃ and TL intensity was decreased 37-60% resulting from FGFE treatment. After 6 months of storage, all the samples showed a decrease in TL intensity, but identification was still possible. The sprouting rate of irradiated samples decreased by about 72%, whereas that of FGFE-treated irradiated samples showed by about 85%, as compared to non-irradiated samples. More detailed study is required to investigate sprouting phenomena for FGFE-treated samples.

The quality of food, what tea is, and the classification of tea are summarized. In addition, the fundamental concepts of the non-material energy is introduced to show how it is overlooked in the conventional way of quality evaluation of food and how the non-material energy works on the tea quality and tea taste. The mechanisms or principles of an evaluation of the non-material value and the methodical way of the “Seulgino” process were explained in detail. Finally, several study cases by the application of Full-overlapped Gravitational Field Energy (FGFE), were performed to recover or improve the non-material energy for food and the tea quality were also provided through examples. In current modern science, food energy is assessed by the analyzable material energy only, but it should also include the non-material energy, which is not analyzed by modern science. Furthermore, the tea industry or tea drinkers should play an important role in adapting their way of life to the new paradigm of the non-material energy.

Changes of physicochemical properties during the preparation of persimmon pickles were investigated. The salinity in persimmon pickles increased during storage time $(0{\sim}50\;days)$ with soy sauce and soy paste. When the fermented soy sauce and soy paste was added to the soaking solution with $80{\sim}100%$, the salinity increased more rapidly. The hardness of persimmon pickles with soy sauce and soy paste was slightly increased up to the 20 or 30th day of storage and then decreased. L value of persimmon pickles was gradually decreased, but a and b value were slightly increased. The concentration of soluble tannin in persimmon pickles was slightly decreased down to the 20th day of storage and then decreased rapidly. The activities of polygalacturonase and pectinesterase as softening enzyme in persimmon pickles with soy sauce and soy paste increased during storage time $(0{\sim}50\;days)$ and enzyme activity was inhibited by high concentration of soaking solution. 떫은감 품종의 하나인 둥시를 이용하여 감장아찌 제조 중 과육의 이화학적 변화를 조사한 결과, 염도 변화는 저농도 간장 및 된장 침지의 경우 다소 완만한 증가를 보였고, 고농도의 간장 및 된장 침지의 경우 침지 기간 내내 증가하는 것으로 나타났다. 간장 침지액 감장아찌의 경도는 간장 및 된장 모두 $20{\sim}80%$ 농도에서는 침지 초기에는 증가하다가 침지 기간이 경과할수록 감소하는 경향을 나타내었다. 간장 침지 감장아리의 색도 변화는 저장기간이 경과할수록 명도가 낮아지는 경향이었고, 적색도와 황색도는 침지액 농도를 달리하였을 경우 농도가 낮을수록, 침지 기간이 길어질수록 높았으며, 침지액 농도에 따른 차이는 크지 않았다. 침지액의 간장 및 된장의 농도를 달리하였을 때 감장아찌 중의 탄닌함량의 변화는 모든 침지액 농도에서 침지 기간이 지속될수록 탄닌의 함량은 저장 초기에 서서히 감소되다가 침지 기간이 길어질수록 급격히 감소하였으며, 첨가량에 따른 탄닌함량의 변화폭은 크지 않았다. 침지액의 간장 및 된장의 농도를 달리하였을 때 감과육에 존재하는 연화효소인 polygalacturonase와 pectinesterase 활성 변화는 간장침지 및 된장침지 모두 침지 초기부터 효소활성이 증가하기 시작하였으며 침지 기간이 경과할수록 효소활성은 더욱 높아지는 것을 알 수 있었고, 침지액의 농도가 높아질수록 효소활성이 억제되었다.
압출성형기의 스크류 회전속도와 원료수분함량이 대두단백질의 조직화에 미치는 영향
한억,이상효,이현유,오상룡,이철호,Han, Ouk,Lee, Sang-Hyo,Lee, Hyun-Yu,Oh, Sang-Lyong,Lee, Cherl-Ho 한국식품과학회 1989 한국식품과학회지 Vol.21 No.6
분리대두단백의 조직화에 대한 스크류 회전속도와 원료 수분함량의 영향을 조사하였다. 수분함량이 증가함에 따라 토출구온도는 감소하였으며 210rpm에서 가장 높은 온도를 나타내었다. 수용성 질소지수는 수분함량이 증가할수록 감소하였으며 고속보다는 저속에서 감소폭이 컸다. 조직잔사지수는 낮은 수분함량과 고속 rpm에서 높게 나타났으며 조직감의 강도는 이와 반대의 경향이었다. 또한 원료의 수분함량이 증가할수록 최종 압출성형물의 수분함량이 증가하였고 고속 rpm일수록 낮은 수분함량을 나타내었다. 밀도의 경향도 이와 일치하였다. 재흡수력의 경우는 수분함량 30%에서 최고치를 나타내었으며 고속 rpm에서 증가하였다. 복원전의 명초는 복원 후 보다 높은 수치를 보였고 고속회전일 수록 명도가 밝아졌다. 성상에 있어서도 저수분, 고속 rpm에서 높은 명도와 높은 정화도가 관찰되었다. 분산분석을 통해서 스크류 회전속도보다 원료의 수분함량이 조직화 성질을 나타내는 각 지표에 더 깊은 영향을 주는 것으로 확인되었다. The effects of screw speeds and moisture contents on the physical properties of texturized extrudate from isolated soy protein were examined by using a single-screw extruder. The screw speeds and moisture contents tested were in the range of 122-334 rpm and 20-35%, respectively, and die temperature were $90-145^{\circ}C$. The texturization characteristics such as nitrogen solubility index, integrity index, chewiness, density, rehydration ratio, and lightness after rehydration were appeared to be influenced by screw speed and moisture content. As the screw speed increased and moisture content decreased, die temperature, nitrogen solubility index, integrity index, lightness before and after rehydration were increased, while chewiness, density, water content of final extrudate wee decreased. The rehydration rate was changed drastically at the feed moisture content of 30% in particular. As the moisture content decreased, the air cell size became large and its number was increased. The effects of interaction between screw speed and moisture content of raw materials on the extrudate characteristics were tested by the analysis of variance.
