We investigated noodles supplemented with functional ingredients for their antioxidant properties, including total phenol, flavonoid contents, electron donating, nitrite scavenging abilities and ferrous ion chelating effect. The total polyphenol contents of functional noodles arranged in order of decreasing concentration were kudzu (7.98%) > green tea (4.99%) > pumpkin (5.03%) > mulberry leaves (4.99%) > mugwort (4.23%) > cactus (3.57%) > kelp (3.33). The total flavonoid contents in green tea noodles were the highest as 4.35%. The electron donating ability in mugwort noodle was the highest as 12.27% at 1,000 ppm. This amount was 4.85 times than that of wheat flour noodle (2.53%). The nitrite scavenging ability of functional noodles at pH 1.2 arranged in order of decreasing concentration were green tea (66.52%) > cactus (55.12%) > kudzu (52.67%) > pumpkin (50.50%) > mulberry leaves (43.58%) > kelp (41.41%) > mugwort (37.66). The nitrite-scavenging ability of green tea noodle was lower than ascorbic acid (natural antioxidant) 77.83%, while that of green tea noodle was similar with BHT (artificial antioxidant) 69.45%. The ferrous ion chelating effect of noodles containing kelp were the highest as 27.02%. All of the experimental results showed good antioxidant property. Thus, noodles supplemented with mulberry leaves, cactus, mugwort, green tea, pumpkin, kelp or kudzu, demonstrated to have good functional effects for human health.

생된장에 감귤, 녹차 및 선인장을 건조 분말 상태로 3%, 7% 첨가하여 $4^{\circ}C$, $20^{\circ}C$, $30^{\circ}C$ 에서 60일간 숙성 시킨 후 된장제품의 품질 특성 및 관능적 특성에 대하여 조사하였다. 일반성분을 분석한 결과, 수분은 전반적으로 55~59%로 대조구에 비하여 큰 차이가 없었고, 3% 첨가 시 수분 유지력이 우수한 것으로 나타났다. 조회분과 조단백질의 함량은 대조구에 비하여 유의한 차가 없었다. 각 된장의 조지방 함량은 대조구에 비하여 약간 증가됨을 볼 수 있었으며, 감귤, 선인장, 녹차 첨가 된장의 탄수화물의 함량은 대조구에 비하여 7% 첨가 시 유의적인 차이를 보였으며, pH는 대조구에 비하여 감귤, 녹차, 선인장 첨가 된장 모두 낮음을 보였다. 아미노산성 질소는 감귤 분말 3% 첨가 된장과 녹차 분말 첨가 된장의 $4^{\circ}C$ 숙성 시 증가됨을 보였고, 총 아미노산 함량은 감귤 분말 첨가 된장에서 대조구에 비하여 높은 함량을 보였으며, 전체적인 기호도는 감귤 3% 첨가 된장의 기호도가 상대적으로 높은 것으로 평가되었다. 이상의 결과로부터, 천연의 향미와 기능 성분을 갖는 감률 된장의 제조 가능성을 확인하였고 감귤을 활용한 제품 개발로 된장의 기호성 향상에 도움이 될 것으로 기대된다.

We investigated the physical and cooking properties of commercial noodles supplemented with functional ingredients. RVA (rapid visco analyzer), color, water activity, texture and cooking properties were tested. Noodles containing kudzu showed the highest initial gelatinization temperatures, whereas noodle containing kelp displayed the highest peak viscosity and set back. Holding strength and final viscosity were highest in noodles containing mugwort. The L value ($94.89{\pm}0.02$) of wheat flour noodle was the highest. Among functional noodles, L value ($88.65{\pm}0.01$) and a value ($7.42{\pm}0.02$) of cactus noodle were the highest, whereas b value of pumpkin noodle was $40.81{\pm}0.03$, which was higher value than in other noodles. Water activity of cactus noodle was highest (0.455), but the difference was not significant. Cooking properties (including weight, volume, and water absorption) and turbidity of pumpkin noodles showed the highest growth rate. In terms of texture, hardness was highest ($12836.8{\pm}7.1g/cm^2$) in green tea noodles, and cohesiveness and gumminess were highest in kelp and mugwort noodles. Considerig the quality characteristics of noodles supplemented with mulberry leaves, cactus, mugwort, green tea, pumpkin, kelp or kudzu, pumpkin noodles were most stable in terms of gelatinization and cooking properties.

Being producing and evaluating oat-chocolate were a major goal in this study. There were various steps to make oat-chocolate. First, oat was roasted with an optimum roasting-temperature. Second, discovered the best natural antioxidant to extend storage period and improve quality of goods. Third, developed processing goods and made an evaluation of quality properties. We selected optimum roasting condition of $160^{\circ}C$ for 15 min based on the acid value and the sensory characteristics such as color, taste, smell and overall preference of oat flour. As for natural antioxidants, we made use of 3 kinds of antioxidants (cactus, lavender and green tea) and two concentrations (0.5 and 1%). In investigating antioxidants, an acid value was significantly decreased as the antioxidants were added (p<0.05). Nothing was as low in acid value as a chocolate with 1 % lavender flour in 7 days. Findings showed the sensory characteristics of products containing antioxidants such as green tea and cactus, were higher than those of Cont. in 7 days. A product including 0.5% green tea marked the best sensory score among antioxidants. Compared cost among 3 antioxidants, green tea was the cheapest. In the end, 0.5% green tea was selected as an optimal antioxidant to make high-quality oat chocolate. We made an end product by mixing green tea (0.5%) and oat. With respect to Hunter's color L (whiteness), a (redness) and b (yellowness), as green tea added, L and a level showed an increasing tendency. However, an opposition result was expressed in b level. When compared pH value and total acidity, it was statistically identical between Cont. and product with 0.5% green tea (G-0.5). There was different acid value among specimens. The acid value of G-0.5 was lower than that of Cont. up to 7 days, resulting in lower acid value than a ready-made product (D-Co.). When we assessed the sensory characteristics, G-0.5 was higher than other specimens such as Cont. and ready-made products (D-Co. and H-Co.) up to 6 days after manufacture. Put previous findings together, the addition of 0.5% green tea increased an antioxidative effect as well as the sensory acceptability of oat-chocolate.
