Status of blood minerals and their absorption by neonate calves as influenced by fat soluble vitamins supplementation in their respective mothers, mineral supplementation in calves themselves has been evaluated. The objective was to know the impact of antioxidant vitamin supplementation to advance pregnant buffaloes, on enhanced acquired immunity during first few hours after birth, in relation to weight gain in buffalo calves. Advance pregnant buffaloes (n = 30) consisting of average body weight of $550{\pm}15$ kg and of 4-6 parity were fed on 25 kg green (green Jawar-Sorghum bicolor), 2-3 kg wheat straw and 3-4 kg concentrate mixture individually per day. Intramuscular injections of vitamin triplex A $D_3$ E consisting of -2,500,000 IU of vit A -Palmitate; 2,500,000 IU of vitamin $D_3$ and 1,000 IU of vit E (dl-alpha tocopherol acetate) were given per dose, a month prior to parturition, twice at 15 days interval to 15 dams. Rest of the 15 pregnant buffaloes served as negative controls. Secretion of immune proteins, immunoglobulin (Ig) enhanced by 80% in colostrum. The blood serum levels of Zn, Cu, Ca, Mg were measured from birth to 90 days in calves. A significant (p<0.05) difference between the blood serum Zn levels of calves born to vitamin supplemented and non-supplemented dams was measured and a positive correlation between blood serum Zn levels and injections of vitamins was identified. Association of Zn and Cu with passive immunity status has been identified in these calves. A significant positive correlation between Zn and Cu was also identified which showed a change under the impact of vitamin supplementation in buffaloes. The study signifies the role of micronutrients supplementation in dams prior to parturition, in calf immunity development. The study indicates significant mineral - vitamins interactions during this process.

Probiotics provide a symbiotic relationship and beneficial effects by balancing the human intestinal microbiota. The relationships between microbiota changes and various diseases may predict health abnormalities and diseases. Treatment with vitamins and probiotics is one therapeutic approach. To evaluate the effect of probiotics on vitamin absorption, we chose Lactobacillus rhamnosus CBT-LR5 treatment, which has resistance to vitamin C-inducible toxicity, with vitamins in high-fat diet (HFD)-induced obesity models. CBT-LR5 affected the absorption of micronutrients, such as ionic minerals and water-soluble vitamins. An increase in vitamin C absorption by CBT-LR5 enhanced the antioxidant response in HFD-induced obesity models. Increased vitamin B absorption by CBT-LR5 regulated lipid metabolism in HFD-induced obesity models. These favorable effects of CBT-LR5 on the absorption of vitamins should be investigated as candidate therapeutic target treatments for metabolic diseases.

본 연구는 멸균 방법 중 하나인 수력학적 공동현상을 이용한 살균처리로 인한 우유의 비타민, 무기질 및 지방 함량에 대한 영향을 조사하고자 한다. 비타민(vitamin A, vitamin $B_2$),무기질(Ca, P, Mg, Zn) 및 조지방 함량을 식품의약품안전처의 축산물 가공기준 및 성분규격 실험법에 따라 측정하였다. Vitamin A는 처리 후 약 23% 감소하였고, vitamin $B_2$는 약 19% 감소하였다. 무기질의 경우, 처리 전후의 함량 차이가 거의 보이지 않았다. 또한 P는 2 mg/100g, Mg은 0.1 mg/100g의 함량 차이를 보였다. 우유의 조지방 함량은 처리 전 3.46%, 처리 후 3.41%로 차이가 거의 나타나지 않았다. 수력학적 공동현상 처리 시 우유의 비타민과 무기질 함량을 변화시키지 않아 기존 살균 방법을 대체할 수 있는 가능성을 보여주었다. 따라서 기존 가열 살균처리 시 발생하는 이화학적 특성 및 품질의 변화를 강조하고, 우수한 품질의 우유를 공급하기 위하여 수력학적 공동현상 살균처리에 대한 명확하고 체계적인 연구가 더 이루어져야할 것으로 보인다.

Fresh-cut 채소 제품이 소비자에 의해 선택되어 소비되려면 이의 친환경적 원료생산과 가공, 포장, 서빙에 이르는 전 과정에서 체계적인 품질관리가 이루어져야 하며 갈변제어, 연화제어 및 미생물적 제어 등 관련 기술의 연구개발이 요구된다. 본 연구에서는 시중 유통 판매되고 있는 fresh-cut 채소제품의 품질을 비교평가하기 위해 현재 유통되고 있는 9개사 제품을 선정하였으며, 관능검사를 포함하여 vitamin C, 무기질, 중금속 함량, 잔류농약 및 미생물오염 정도를 조사하였다. 관능평가에서는 갈변 등 품질변화로 인해 전반적인 기호도가 그다지 높지 않았다. 채소류에서 중요 영양성분인 vitamin C 함량은 9개사 모든 제품의 주재료인 양상추에서 거의 검출되지 않았고 다른 채소류의 vitamin C 함량 역시 식품성분표보다 소량이었다. 무기질 함량 역시 극히 소량이었는데, 이는 박피, 절단 등의 최소 가공 공정을 거치면서 파괴되기 쉬운 vitamin C와 무기질이 대부분 손실되었기 때문으로 사료된다. 안전성측면에서 평가한 잔류 중금속 함량의 경우 몇 개의 제품에서 구리와 납이 소량 검출되었으며 잔류농약은 검출되지 않았다.

Purpose: We have investigated for the purpose of studying change of vitamins and minerals in frequently used vegetables by low moisture cooking method. Methods: Vitamin B complex, vitamin C and mineral (Mg, Ca, K, Zn, Fe) contents are analyzed in vegetables such as spinach, cabbage, bean sprouts and carrot which are heat-treated with degrees of water contents. Low moisture cooking method represents heat-treated vegetable (LM experiment group) with 25 wt.% water content for the vegetable weight while general blanching method includes heat-treated vegetable (GB experiment group) with 500-1,000 wt.% water content for the vegetable weight. Results: Retention rate of vitamin B1 (thiamin) in the LM experiment group is relatively high (87.50-95.68%) and dosen't show considerable differences from raw vegetables. On the other hand, the retention rate of vitamin $B_1$ in GB group's cabbage and spinach dramatically decreased to 19.46-25.00%. Retention rate of vitamin B2 (riboflavin) is sustained stably in LM experiment group (75.00-87.50% in bean sprouts, cabbage and spinach), represents that low moisture cooking method has relatively higher contents in vitamin $B_2$. The LM experiment group has 71.43-85.71% on retention rate of niacin while the GB group shows relatively lower niacin (57.14-64.58%), represents conflicting results from the general idea that vitamin $B_3$ is relatively stable in heat treatment and blanching. Retention rate of pantothenic acid is considerably higher in both LM and GB experiment group, indicates vitamin pantothenic acid is relatively stable in the various cooking condition such as amount of water and heat treatment. In the experiment under various water contents, vitamin C is not detected in both bean sprouts and carrots, while the contents in cabbage and spinach are 19.87 mg/100 g and 26.65 mg/100 g respectively. In the same experiment, the retention rate of Vitamin C in LM experiment group (91.65%, 92.23%) is considerably higher than GB group (58.08%, 61.61%). Retention rate of Mg, K, Fe in the LM experiment group is relatively higher than GB group. Conclusion: Resultingly, the observations suggests that minimum water quantity and minimum heat treatment processes should be established in cooking vegetables which have soluble vitamins and minerals.

The nutritional evaluation, and antimutagenic and anticancer effects of Kimchi were reviewed. Kimchi contains high levels of vitamins including vitamin C, $\beta$-carotene, vitamin B complex, niacin, and of minerals such as calcium, potassium, iron and phosphorous, etc. Kimchi is a low energy food, byt contains high quantities oforganic acids, dietary fiber and lactic acid bacteria in addition to the vitamins and minerals. Thus Kimchi could be developed as a protective food as it contains the various regulatory nutrients. The levels of NO3, NO2 and nitrosamines in Kimchi ingredients and Kimchi during theripening are not significant. However, high level of NaCl that could be used when prepared Kimchi in the warm region can be a problem, since high concentraitons of NaCl(>9.5%) in Kimchi could be comutagenic to themutagen of MNNG. The methanol extract of Kimchi, red pepper powder, garlic and lactic bacteria revealed antimutagenic or anticancer activities. The Kimchi extract also inhibited the growth of various human cancer cells.

This study was performed to investigate the change of chemical components and antioxidant activities in Hizikia fusiformis(Harvey) OKAMURA with blanching times. For chemical composition, the contents of minerals (K, Ca, Na, Mg, Fe, Cu, Mn and Zn), vitamins (vitamin C, ${\beta}$-carotene and ${\alpha}$-tocopherol) and total polyphenol were analyzed. The antioxidant activity was determined through free radicals (DPPH radical, superoxide anion radical, hydroxyl radical and hydrogen peroxide) scavenging activity and linoleic acid peroxidation inhibitory activity. As the blanching time increased, the contents of all minerals, vitamin C and total polyphenol decreased. However ${\beta}$-carotene and ${\beta}$-tocopherol were not affected by the blanching time. In addition antioxidant activities decreased with increasing blanching time.
