The desmutagenic effects of seaweed and vegetable extracts were investigated on the mutagenicity of Maillard reaction products (MRP) obtained from equimolar amounts of glucose and amino acid (arginine and lysine${\cdot}$HCl) for Salmonella typhimurium TA 100 without S9 mix. The mutagenicities were inhibited by water-soluble extracts of seaweeds(laver, sea-straghorn, sea-mustard and tangle) and vegetables(ginger, garlic, onion, chinese-pepper, green-onion and cabbage). Cabbage, chinese-pepper, green-onion and sea-straghorn exhibited especially high desmutagenic effects. The desmutagenicities of these extracts(cabbage, green-onion and sea-straghorn) except for sea-straghorn were decreased by heat treatment at $100^{\circ}C$ for 10 min. It is assumed that the desmutagenic effect of seaweed and vegetable extract is due to the reducing power and action of enzyme such as peroxidase and catalase.

This study was conducted to investigate the effect of the addition of Hizikia fusiforme, Capsosiphon fulvescens, and Undaria pinnatifida sporophyll on the antioxidant and inhibitory potentials against key enzymes related to type 2 diabetes of a commercial vegetable extract. The nutritional quality and mineral concentration of a vegetable extract with seaweeds added were also analyzed. The addition levels of seaweed did not influence the proximate composition, whereas the calcium, sodium, potassium, magnesium, and iron concentrations significantly increased at the 5% Hizikia fusiforme and Undaria pinnatifida sporophyll addition levels. The 20% Hizikia fusiforme addition level significantly increased the total phenolic content and reducing power by 47.08% and 16.82%. The hydroxyl radical scavenging ability of the vegetable extract was not strengthened with the addition of seaweeds. The DPPH radical scavenging activity at the 20% Hizikia fusiforme, Capsosiphon fulvescens, and Undaria pinnatifida sporophyll addition levels significantly increased by 27.47%, 22.25%, and 17.27%, respectively. The vegetable extract with seaweeds added showed higher-level ${\alpha}$-glucosidase inhibition activities, accompanied by relatively weaker ${\alpha}$-amylase inhibition activity. In particular, at the 5% Undaria pinnatifida sporophyll addition level, the ${\alpha}$-glucosidase activity was significantly inhibited by 98.26%. Overall, the results showed that the incorporation of seaweeds into a vegetable extract effectively increased the mineral concentration and improved the antioxidant and inhibitory abilities of the extract on key enzymes linked to type 2 diabetes.

The present paper was investigated in the inhibitory action of vegetable and seaweed water-soluble extracts on the formation of carcinogenic N-nitrosodimethylamine(NDMA). The vegetable and seaweed extracts obtained from garlic(Allium sativum), onion(Allium cepa), green onion(Allium fistuiosum), chinese pepper(Fagara mandshurica), green pepper(Capsicum annuum), red pepper(Capsicum annuum), ginger(Zingiber officinale), carrot(Daucus carota), laver(Porphyra tenera), sea lettuce(Entero compresa), sea mustard(Undaria pinnatifida) and sea staghorn(Codium fragile) were incubated with sodium nitrite-dimethylamine mixtures at $37^{\circ}C$ under different pH conditions The formation of NDMA was reduced to $10{\sim}40\%\;and\;25{\sim}50\%$ by the addition of vegetable and seaweed extracts 30mg at pH 1.2, respectively. The inhibition degree by the extracts at pH 1.2 was similiar to that at pH 4.2 and to that by ascorbic acid at pH 1.2. The inhibitory action of the extracts against NDMA formation was not decreased by heat treatment at $80^{\circ}C$ for 10min, but decreased by the treatment of sodium borohydride. It is assumed that reducing powers of the extracts participated in their inhibitory actions.

Major egg white proteins and their hydrolysates serve as functional food ingredients that have certain metal-chelating properties. Employing egg white proteins and their hydrolysates to scavenge dietary oxalates is anticipated to have beneficial effect in the prevention of kidney stones. The objective of this study was to determine the biogenic oxalate-chelating activity of ovalbumin, ovomucin, and ovotransferrin and their hydrolysates. To prepare oxalate extracts, 30 mL of 0.25 N HCl was added to separately to 0.5 g of dried spinach and starfruit powders followed by boiling for 15 min, and after cooling, the addition of a further 20 mL of 0.25 N HCl. Having prepared these extracts, ovalbumin, ovomucin, and ovotransferrin and their hydrolysates were separately mixed with oxalate extracts and incubated at 3℃ for 24 h. Following centrifugation, supernatants were analyzed by HPLC using a reverse-phase C18 column coupled with a diode array detector. We found that all assessed proteins and their hydrolysates showed biogenic oxalate-chelating activity against the oxalates of spinach. In contrast, however, only ovalbumin, ovalbumin-hydrolysate, and ovomucin showed chelating activity (57.10%±8.84%, 85.44%±5.30%, 73.20%±4.13%, respectively) against the oxalates of starfruit (P<0.05). Overall, hydrolyzed ovalbumin was identified as the most effective chelator of the oxalates both spinach and starfruit. In this study, we thus established that the assessed egg white proteins and their hydrolysates have oxalate-chelating activity in vitro, thereby indicating that these compounds have potential utility as nutraceuticals for the chelation of dietary oxalate. However, further research will be necessary to verify their oxalate-chelating activities against different fruits and vegetables and under specific in vivo conditions and against purified oxalate.

This study was attempted to investigate the occurrence and the characteristics of ascorbic oxidase in cucumbers. Ascorbic acid oxidase was isolated from cucumbers and concentrated using ammonium sulfate precipitation. The results of this study are as follows ; 1) Ascorbic acid oxidase activity was detected in whole cucumber homogenate. 2) Highest amounts of ascorbic acid destroyed after 10 minutes' incubation of ascorbic acid oxidase with its substrate. 3) The optimum pH and temperature of this enzyme were found to be pH 6.5 and $40^{\circ}C$, respectively. 4) Ascorbic acid content in cucumber juice prepared using the cold water $(4^{\circ}C)$ was higher than that made with water at $30^{\circ}C$. 5) When orange juice ( pH 3.4 )was added, ascorbic acid destruction was completely ceased. (The ascorbic acid oxidase was inactivated at pH 3.9) Decreasing the temperature and pH are recommended to achieve maximum stability of ascorbic acid in preparing cucumber juice.

The anticarcinogenic effects of various food components have received much attention in recent years. However mechanism of anticarcinogens in food materials on cancer cells have rarely been investigated. This study was performed to investigate the effects on the cytotoxicity and quinone reductase (QR) activity of Allium tuberusum (AT) on the human cancer cells. The six partition layers which are methanol (ATM), hexane (ATMH), ethylether (ATMEE), ethylacetate (ATMEA), butaonl (ATMB) and aqueous (ATMA) of Allium tuberusum were screened for their cytotoxic effects on HepG2, MCF-7, HeLa and SK-N-MC cells by the MTT assay. Among the six partition layers, ATMEE had the strongest cytotoxic effect at concentration of $150\;{\mu}g/mL$ which resulted over 95% on HepG2, HeLa, MCF-7 and SK-N-MC cell lines. The ATMEA also showed significant cytotoxic effect on HepG2 and SK-N-MC cell lines. The ATMB showed the highest induction activity of QR on HepG2 cells among the other partition layers. QR activity of HepG2 cells, grown in the presence of ATMB at the concentration of $50\;{\mu}g/mL$, was increased by 3.9 times, compared to the control value of 1.0. Based on these results, the ATMEE and ATMB may have potentially anticarcinogenic and chemopreventive activities.

암 발생의 원인 중 80% 이상이 식사습관과 환경오염에 있는 것으로 인정되고 있다. 음식물, 담배, 술, 대기오염, 스트레스, 자외선이 그 대표적인 원인물질로 꼽을 수 있으며 그 중에서도 매일 섭취하는 음식물이 가장 중요한 발암요인으로 지적되고 있다. 대장암과 유방암의 발생에 대한 Wynder 등의 역학조사에서도 식사습관이 암 발생에 중요함을 시사 하고 있다. 동물성 단백질과 지방의 다량 섭취가 대장암과 유방암의 발생을 증가 시키고 섬유질이 풍부한 곡류와 야채의 섭취는 대장암 발생을 억제한다는 상관관계가 밝혀졌다. 그러나 우리가 늘 섭취하는 음식물 자체는 대장암과 유방암을 유발하는 기능이 거의 없다. 섭취된 음식물이 암을 일으키려면 장내 부패 미생물의 분해작용에 의하여 발암물질로 변환되는 과정이 필요하다. 그 발암물질들이 장관으로 흡수 자극함으로써 암을 유발할 수 있다. 반대로 일부장내 미생물들은 장내 발암물질들을 무독화 하거나 숙주의 면역기능을 증강 시킴으로써 암 발생을 억제할 수도 있다는 사실을 간과해서는 안 될 것이다. Mitsuoka는 장내 미생물이 암을 유발하는 중요한 요인이라고 강조하였다. Veer 등은 유산균 발효유를 많이 섭취하면 유방암 발생이 억제됨을, 국제암연구위원회는 섬유질을 많이 섭취하고 있는 핀란드 쿠피오의 거주자들에게는 덴마크의 코펜하겐에 거주하는 사람들에 비하여 대장암 발생율이 1/4에 불과하고 분변내 유산간균수는 100배 높은 사실을 역학조사에서 밝혔다. 이 외에 유산균과 발효유제품의 항암효과에 대한 실험결과들이 많이 발표되었다. 여기에서는 유산균의 항암효과에 대한 지금까지의 관련 자료들을 요약, 정리하여 고찰하고자 한다.높은 당 함량을 나타냈으며, T-AS는 70.3%의 당과 7.8%의 단백질로 구성 되었다.
