  • Zn is an essential nutrient that is required in humans and animals for many physiological functions, including immune and antioxidant function, growth, and reproduction. The present study evaluated whether Zn deficiency would negatively affect bone-related enzyme, ALP, and other bone-related minerals (Ca, P and Mg) in rats. Thirty Sprague Dawley rats were assigned to one of the three different Zn dietary groups, such as Zn adequate (ZA, 35 mg/kg), pair fed (PF, 35 mg/kg), Zn deficient (ZD, 1 mg/kg) diet, and fed for 10 weeks. Food intake and body weight were measured daily and weekly, respectively. ALP was measured by spectrophotometry and mineral contents were measured by inductively coupled plasma-mass, spectrophotometer (ICP-MS). Zn deficient rats showed decreased food intake and body weight compared with Zn adequate rats (p<0.05). Zn deficiency reduced ALP activity in blood (RBC, plasma) and the tissues (liver, kidney and small intestine) (p<0.05). Also, Zn deficiency reduced mineral concentrations in rat tissues (Ca for muscle and liver, and Mg for muscle and liver) (p<0.05). The study results imply the requirement of proper Zn nurture for maintaining bone growth and formation.

  • The dietary habits and eating behaviors of nonagenarian subjects over 90 years old in Korean representative longevity belts of Damyang, Gokseong, Kurye, Sunchang were evaluated. The subjects of the study were 91 elderly people (26 males and 65 females) over 90 years old and their dietary habits, food preferences and meal patterns were collected by individual interview. The percentage of subjects, who answered 'very good' or 'good' for their health status, was $65.9\%$. In this study, $55\%$ of subjects were without chronic diseases, and there was no significance difference in gender. Many subjects had performed regular exercise and outdoor activity. The rate of eating together with their family was $79.1\%$. Most of subjects ($91.2\%$) had a regular mealtime consuming three meals a day, and they had good appetite and pleasure of eating. The higher preference of food group was fruits ($95.6\%$), legumes ($94.5\%$), mushrooms ($93.4\%$) and vegetables ($92.3\%$), but the amount of intakes is higher in vegetables than the others. Eating with family, regular exercise and self-rated good health are improved their nutrient intakes. Most frequently consumed meal pattern was rice plus soup and side dishes. The side dish consumed frequently was Namul (blanch and seasoned vegetables). From this study, the nonagenarian populations in longevity belt in Korea have good dietary habits such as regular mealtime, constant amount of meal and eat with pleasure. They are taking Korean traditional meal pattern, providing enriched antioxidant vegetable foods. Also, it can be concluded that the amount and quality of diet in the long-lived elderly are responsible for the Korean traditional family system.

  • In order to examine the cross-tolerance of two chilling-tolerant cultivars (Donganbyeo and Heukhyangbyeo) and two chilling-susceptible cultivars (Hyangmibyeo and Taekbaekbyeo) to salt, paraquat, and drought, changes of physiological response and antioxidant enzymes were investigated. The seedlings were grown in a growth chamber until the 4-leaf stage. The seedlings were exposed to chilling at $5^{\circ}C$ for 3 days. For drought treatment, the seedlings were subjected to drought by withholding water from plants for 5 days. For paraquat study, plants were sprayed with $300{\mu}M$ paraquat. For the salt stress, the seedlings were transferred to the Hoagland's nutrient solution containing 0.6% (w/v) NaCl for 4 days. Chilling-tolerant cultivars showed cross-tolerant to other stresses, salt, paraquat, and drought in physiological parameters, such as leaf injury, chlorophyll a fluorescence, and lipid peroxidation. The baseline levels of antioxidative enzyme activities, catalase (CAT) and peroxidase (POX) activities in chilling-tolerant cultivars were higher than in the chilling-susceptible cultivars. However, there were no differences in ascorbate peroxidase (APX) and glutathione reductase (GR) activities between chilling-tolerant and -susceptible cultivars in untreated control. CAT activity in chilling-tolerant cultivars was higher than that in chilling-susceptible cultivars during chilling, salt, and drought treatments, but not during paraquat treatment. However, other antioxidative enzymes, APX, POX, and GR activities showed no significant differences between chilling-tolerant and -susceptible cultivars during chilling, salt, paraquat, and drought treatments. Thus, it was assumed that CAT contribute to cross-tolerance mechanism of chilling, salt, and drought in rice plants.

  • 본 연구는 동양 식품학과 서양 식품학 원리의 융합적 접근을 통해 식품의 새로운 가치를 찾아보고자 계획, 수행되었다. 이에 따라 백복령, 산약, 연육 및 검인 등 4가지 재료에 대해 기미(氣味)를 기초로 섭취효능을 정리하였고, 일반 영양성분, 무기질, 유리당 및 항산화활성을 분석하여 동 서 융합적 섭취효능에 대한 접근을 시도하였다. 동양 식품학적으로 4가지 재료들은 소화기관인 비위(脾胃)를 건강하게 하는 섭취효능이 있음을 확인하였고 서양 식품학적으로는 인의 함량이 높은 탄수화물 급원식품임을 알 수 있었다. 또한 전자공여능에 의한 자유기 소거능, ABTS 자유기 소거능, SOD 유사활성을 통해 분석한 재료들의 항산화 활성은 검인의 활성이 다른 재료들에 비해 유의적으로 높게 나타났다. 영양성분 함량 또는 기미 분석만으로는 이 재료들의 특징을 온전히 이해하기에는 한계가 있다고 보여진다. 이에 따라 식품에 대한 다양한 측면에서의 특성을 접근해 보는 시도가 필요함을 인지할 수 있다. 본 연구결과는 재료의 동 서 융합적 특성과 효능을 돌출하여 향후 이 재료들을 활용한 건강음식, 기능성 식품 등의 레시피 구성을 위한 근거자료 및 식품의 특성을 판단할 때 동 서 융합적 시각의 필요성을 인지하는데 기초자료가 되리라 사료된다.

  • Background: Korean ginseng (Panax ginseng Meyer) powder is in rising demand because powder forms of foods are convenient to handle and are highly preservable. However, ginseng powder (GP) manufactured using the conventional process of air drying and dry milling suffers nutrient destruction and a lack of microbiological safety. The objective of this study was to prepare GP using a novel process comprised of UV-TiO2 photocatalysis (UVTP) as a prewashing step, wet grinding, high hydrostatic pressure (HHP), and freeze-drying treatments. Methods: The effects of UVTP and HHP treatments on the microbial population, ginsenoside concentration, and physiological characteristics of GP were evaluated. Results: When UVTP for 10 min and HHP at 600 MPa for 5 min were combined, initial 4.95 log CFU/g-fw counts of total aerobes in fresh ginseng were reduced to lower than the detection limit. The levels of 7 major ginsenosides in UVTP-HHP-treated GP were significantly higher than in untreated control samples. Stronger inhibitory effects against inflammatory mediator production and antioxidant activity were observed in UVTP-HHP-treated GP than in untreated samples. There were also no significant differences in CIELAB color values of UVTP-HHP-treated GP compared with untreated control samples. Conclusion: Combined processing of UVTP and HHP increased ginsenoside levels and enhanced the microbiological safety and physiological activity of GP.

  • This study investigated the nutritional compositions and physiochemical properties of three domestically cultivated jujube fruits (Boeun, Sangwhang, and Bokjo). Nutrient contents were analyzed by freeze-drying the jujube fruits. The results showed that the proximate compositions of the three jujube cultivars ranged from 7.85~13.52% for moisture, 4.65~5.24% for crude protein, 1.29~2.38% for crude ash, 0.17~1.09% for crude lipid, and 7.66~16.63% for crude fiber. The above proximate contents of jujube cultivars were significantly different. Mineral contents of Al, Fe, Mg, Ca, Na, and K in the three jujube fruits were also determined. Mn, Cu and Zn were not detected in any of the varieties. The content of Al was higher in Sangwhang, while Boeun had higher contents of Ca and K. The total polyphenol, ABTS values, and hypoglycemic effect were slightly higher in Boeun as compared to the other varieties. Taken together, Boeun could be an important source of natural antioxidant as a functional food.

  • This study was undertaken to examine the quality characteristics of nonblanched carrots (CON) and carrots blanched in distilled water, 2% NaCl water and 2% citric acid at 100℃ for 3 minutes. This moisture contents of CON was the highest at 85.91%, whereas NT had the lowest moisture at 83.92% (p<0.01). Compared to CON values the L values of pretreatment groups were decreased whereas the b values were increased (p<0.001) A comparison of true retention (TR), revealed that NT had the highest TPC TR 101.04% and TFC TR 91.59% (p<0.001). β-Carotene contents were determined to be higher in NT (1.98 mg/100 g) and CT (1.94 mg/100 g) than in other groups, with highest levels obtained in NT (106.64%) (p<0.001). Examination of the DPPH and ABTS+ radical scavenging activities revealed that the NT group had maximum scavenging activity. The total bacterial count was determined to be 3.37 log CFU/g in the CON, whereas no microorganisms were observed in all the pretreatment groups. Our study indicates that blanching in 2% NaCl water is the most desirable in order to increase the biochemical content and nutrient preservation rate of carrots, and to inhibit the growth of microorganisms.
