This study evaluated the effects of different levels of malt extract on the hardness, moisture, water soluble starch (WSS) contents, and in vitro starch digestibility (IVSD) of Jeungpyun during storage at room temperature (25±1℃) and refrigeration temperature (4±1℃). Resistant starch (RS) and soluble starch (non-RS) contents were also evaluated. During storage at both temperatures, hardness increased in Jeungpyuns with the malt extract-added Jeungpyun groups (malt-added Jeungpyuns) exhibiting lower hardness than the control. The rate of retrogradation was faster upon storage at refrigeration temperature. Moisture and WSS contents as well as IVSD of Jeungpyuns decreased, whereas these levels were higher in malt-added Jeungpyuns compared to control. Storage increased RS contents in Jeungpyuns stored for up to 4 days, particularly at 4℃, whereas there was a decrease in RS content after 7 days of storage. However, RS content was lower in malt-added Jeungpyuns compared to control. Soluble starch (SS) contents of Jeungpyuns decreased. However, SS content was higher in malt-added Jeungpyuns than that of control. The reduced hardness and RS content as well as the rate of increase in other parameters of malt-added Jeungpyuns were dependent on the concentration of malt extract. These results reveal that addition of malt extract delayed retrogradation of Jeungpyun, whereas retrogradation possibly increased the content of RS during storage at both temperatures, however, that of RS decreased with increasing level of malt extract, suggesting that the level of malt extract as well as the storage conditions are important for obtaining acceptable texture and retaining the RS content of Jeungpyun, which is known to possess physiological activity.

Soybean powder is a readily-available food ingredient. Furthermore, saltwort powder is an herb with various physiological effects. Therefore, in this study we examined the physiochemical characteristics of soybean dasik prepared with 0, 4, 8, and 12% saltwort powder. We measured Hunter's color values, mechanical characteristics, and sensory qualities. The result of each analysis is as follows. There were not significant differences between the moisture content of the control group and the groups with saltwort powder. The ash content increased while the fat and protein content decreased as the ratio of saltwort powder increased (p<0.001). In the analysis of color differences, the L, a, and b values decreased as the ratio of saltwort powder increased (p<0.001). The hardness (p<0.001) of the groups increased as the ratio of saltwort powder increased, but adhesiveness decreased. Sensory evaluation data showed that softness, hardness, and chewiness decreased while color increased as the ratio of saltwort powder increased. Finally, aroma, sweet taste, nutty taste, and overall acceptability was shown to be best for the 4% addition group.

Thermally processed vegetables have long been considered to have lower nutritional values compared to fresh produce. This consideration is based on the fact that ascorbic acid(vitamin C) or other thermolabile compounds may lose their activity due to oxidation or by consequence of leaching into the water during home cooking or industrial processing, such as by blanching. In this study, major agricultural products such as carrots, broccoli, and potatoes were exposed to steam treatments of different types. Then, changes in color and levels of ascorbic acid, carotene, and moisture in the fresh and steam processed vegetable samples were measured and evaluated. The results clearly showed that steam-processing using a natural convection type method was superior to the other treatments in terms of quality, including color and nutrient retention, among all the vegetables tested.

In this study, certain quality characteristics of kimbugak samples prepared with 2 different puffing methods, microwave oven and frying, and containing different levels of sea tangle powder(0, 2, 4, and 6%), were examined according to mineral content, moisture content, color values, photographic images, hardness and sensory evaluations. The mineral contents of Porphyra yezoensis were: K, 2, 612.400 ㎎; Ca, 116.970 ㎎; Na, 486.099 ㎎; Mg, 297.800 ㎎; Fe, 9.636 ㎎; Mn, 1.614 ㎎; and Cu, 0.973 ㎎. And those of the sea tangle powder were: K, 5, 115.000 ㎎; Na, 1, 848.931 ㎎; Ca, 763.030 ㎎; Mg, 525.700 ㎎; Fe, 15.125 ㎎; Zn, 4.639 ㎎; and Mn, 0.146 ㎎. Moisture content was not significantly different among the samples of kimbugak puffed by the microwave oven and frying. For the color of the kimbugak made with the microwave oven or frying, L values decreased as the level of sea tangle powder increased. Color a and b values were lowest in the control group. The color values(L, a, and b) of the kimbugak puffed by frying were higher than those made using the microwave oven. The hardness of the kimbugak samples puffed using the microwave oven were not significantly different according to levels of sea tangle powder, and in the kimbugak puffed by frying, the lowest hardness was in the sample with 6% sea tangle. In sensory evaluations, color and crispness were not significantly different among the samples. The flavor scores of the 4% and 6% samples puffed by frying were higher than those of the kimbugak samples puffed using the microwave oven. The overall acceptability of the kimbugak puffed by frying and containing 6% sea tangle powder was the highest. In conclusion, 4 and 6% sea tangle powder would be considered optimum amounts for kimbugak puffed by frying.

A study was undertaken to examine the effect of the addition of job`s tears(Coixlachryma-jobi L.) chungkukjang(soybeanfermented food) and wheat bran powder on quality attributes of pound cakes. Job`s tears chungkukjang and wheat bran powder was added to the batter at a ratio of 10, 12.5 and 15% respectively. The antioxidant activity was estimated by DPPH free radical scavening activity, the total phenolic compounds content and flavonoid content in job`s tears chungkukjang & wheat bran powder and pounds cakes. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of job`s tears chungkukjang and wheat bran pound cakes respectively(r=0.9671, r=0.8335). The quality characteristics of job`s tears chungkukjang powder and wheat bran powder pound cakes were estimated in terms of the specific load volume, hardness, hunter value of crumb and crust and sensory quality of cakes. The specific volume were increased significantly with increasing substitution level of job`s tears chungkukjang and wheat bran powder(p<0.01). The lightness were significantly decreased with increases in job`s tears chungkukjang and wheat bran powder of pound cake crust and crumb(p<0.01, p<0.01). The hardness, chewiness and gumminess were tended to reduce, while cohesiveness with increase in both of powder. The consumer acceptability score for 10～15% job`s tears chungkukjang and wheat bran powder pound cakes ranked significantly(p<0.01) higher than those of the other groups in taste, flavor and overall preference. This results showed that job`s tears chungkukjang and wheat bran powder are a good ingredient to increase consumer acceptability and the healthy.

This study was conducted to investigate the effect of Nelumbo nucifera G. (NN) powder on cookie quality characteristics. The cookies were made with various NN powder levels (1, 3, and 5%). Crude fiber, crude ash, and the Mg contents of cookies with added NN powder were higher in concentration than those of the control group. Salinity of NN-powder added groups was not significantly different when it was compared with the control group's salinity. No significant difference among the groups were observed for specific volume, but the width determined by water content in the dough decreased as the amount of added NN powder increased. The L-value of the cookies was significantly larger than that of the control group. The a- and b-values were the highest for the 5% substituted NN flour. According to the sensory evaluation of the cookies, scores for color, flavor, and texture increased with increasing amounts of added NN powder. The overall acceptance of the 3% NN added cookies was greater than that of the 1 and 5% cookies.

야콘 분말의 대체량을 0-30%로 달리하여 스펀지 케이크를 제조한 후 물리화학적 및 관능적 품질특성을 비교하였다. 야콘 분말의 대체비율이 증가함에 따라 반죽의 비중은 단계별로 유의적으로 증가하였고 pH는 감소하는 경향을 나타내었다. 한편 케이크의 비체적과 수분함량은 야콘 분말 대체에 따라 유의적으로 감소하였고 굽기 손실은 증가하였다(p<0.05). 부피지수는 감소하는 경향을 보여 야콘 분말 비율이 높아지면 케이크의 부피 또는 높이가 작아짐을 알 수 있었다. 반면 대칭지수는 야콘 분말 대체량에 따른 유의적인 차이를 나타내지 않았다(p > 0.05). 밝기는 나타내는 L*값은 유의적으로 감소하였으며(p < 0.05), 경도는 점차적으로 증가하였으나 20% 및 30% 대체군 사이에 유의적인 차이는 발견되지 않았다. 소비자 기호도 검사결과 대조군, 10% 및 20% 대체군 사이에 전체적인 기호도에 대한 유의적인 차이는 발견되지 않았으나(p > 0.05), 관능품질을 저해하지 않고 야콘 분말의 건강 기능성 효과 등을 고려할 때 20% 대체군이 가장 적절한 것으로 판단된다.

사과박의 식이섬유를 추출하여 설기떡에 첨가 시 첨가량에 따른 저장 중 품질특성변화를 분석하였다. 설기떡의 색도는 식이섬유첨가량이 증가함에 따라서 L*값은 87.9로부터 65.9로 감소하였으며 a*와 b* 값은 각각 -1.9에서 5.9 및 5.0에서 20.5로 증가하였다. 주사전자현미경(SEM)으로 설기떡의 표면구조를 관찰한 결과 식이섬유를 첨가한 설기떡에는 쌀가루사이에 끼어든 식이섬유가 쌀가루간의 연결을 저해하여 대조구보다 치밀한 구조이지 않았으며 사이사이 공간이 형성되어 있는 것을 볼 수 있었다. 대조구, 10% 및 15%의 식이섬유를 첨가시킨 설기떡의 엔탈피 변화는 3일 후 4oC 저장에서 각각 4.83, 3.80 및 3.18 J/g로 나타났으며 25oC 저장에서는 각각 1.14, 0.60 및 0.60 J/g이었으며 식이섬유첨가는 설기떡의 노화를 지연시키는 작용을 하였다. 대조구와 식이섬유첨가 설기떡 간의 경도를 비교하여 볼 때 실온저장보다는 냉장저장 시 경도증가(노화)억제효과가 컸으며 4oC에서 저장 3 일 후 15%첨가 설기떡의 경도는 대조구의 약 42%수준이었다. 기준 검사물과의 차이검사법에 의한 전체적인 기호도 평가에서 15% 식이섬유를 첨가시킨 설기떡이 제조 직후와 4oC 저장에서 3 일 후 모두 가장 높은 값을 보였으며 대조구와 5% 내에서 유의성 차이를 보였다.

본 연구에서는 아마씨 가루를 밀가루 중량기준 0%, 6%, 12%, 18%의 비율로 첨가한 쿠키를 제조한 다음, 반죽의 밀도, pH, 수분 함량, 쿠키의 퍼짐성, 손실률, 팽창률, 경도, 색도, 관능평가, 과산화물가, 산가 등을 측정하였다. 반죽의 밀도는 대조군과 실험군 간에 유의적인 차이가 없었고 pH는 첨가군이 대조군보다 높게 나타났으며 수분 함량은 낮게 나타났다. 퍼짐성은 아마씨 가루 첨가량이 증가할수록 증가하였고(p<0.05) 손실률은 대조군과 6% 첨가군 간에 유의적인 차이가 없었고 12% 첨가군이 가장 높았으며 18% 첨가군이 가장 낮았다. 팽창률은 대조군과 6%, 12% 첨가군 간에 차이가 없는 반면, 18% 첨가군은 대조군보다 감소하였다. 경도는 아마씨 가루 첨가군이 대조군보다 유의적으로 낮았고(p<0.05) 명도와 황색도는 아마씨 가루 첨가량이 증가할수록 감소하였다. 관능검사결과 아마씨 가루 첨가량이 증가할수록 쿠키의 표면색, 고소한 맛이 강하게 평가되었고 전반적인 기호도는 12% 첨가군이 대조군보다 높은 점수로 평가되었다(p<0.05). 저장 기간에 따른 산화 안정성을 측정한 결과 과산화물가는 모든 시료에서 저장 30일까지 증가하다가 감소하였고 산가는 저장기간 동안 지속적으로 증가하였으며 각 시료 간에 유의적인 차이는 없었다.

We evaluated the sensory characteristics of Gangjung base obtained from various manufacturers, using a sensory descriptive analysis. Significant differences were observed for all sensory attributes of Gangjung samples with the exception of 'toothpacking'. Sample A showed high intensities for 'external color', 'external roughness', 'sweetness', 'toasted soybean powder flavor', 'crispness', 'fracturability', 'oiliness', and 'loose particles,' whereas it had low intensities for 'rice flour flavor', 'hardness', and 'toughness' compared to those of other samples. Sample B had more 'sourness', 'butyric acid flavor', 'fermented rice flavor', and 'degree of melting' but lower 'air cell size', 'fracturability', and 'flake roughness'. Sample C showed high intensities for 'expansion', 'hardness', 'crispness', and 'flake roughness', whereas sample D showed low intensities for 'expansion' and 'sourness'. These results indicate that Gangjung base samples are markedly different depending on the manufacturer.

We investigated the quality characteristics of cookies made with Chungkukjang powder. Chungkukjang is a well-known nutritional supplement. Cookie samples were made by adding differrent quantities of Chungkukjang powder(0%, 4%, 8% and 12%). We examined the resulting, moisture, pH, color, spread factor, hardness and sensory evaluation of the cookies. While the moisture and, a and b value of the cookies significantly increased when more Chungkukjang powder was added (p<0.01), the pH, L value, spread factor and hardness of the cookies significantly decreased(p<0.01). Cookies containing 0% and 4% Chungkukjang powder had similar sensory evaluation score in terms of color, taste and flavor cookies made with 4% Chungkukjang powder had the highest texture and overall consumer acceptability scores.

The principal objective of this study was to develop processed food with the effect of extract from Angelica gigas Nakai by assessing the quality characteristics of cookies. Cookie samples were prepared with shredded extract from Angelica gigas Nakai at varied levels of 0, 1, 3, and 5%. The pH of dough decreased significantly with the added extract from Angelica gigas Nakai and the density increased significantly in the 5% added group(p<0.05). The spread factor decreased significantly as the added extract from Angelica gigas Nakai increased(p<0.05). The Hunter color`s L value in cookies significantly decreased and the a, b values in cookies increased(p<0.05). The hardness of cookies significantly increased added extract from Angelica gigas Nakai increased(p<0.05). The acid value and peroxide value were lower in added Angelica gigas Nakai extract groups than in the control group as the storage period of cookies passed. The results of sensory characteristics demonstrated that 1% added Angelica gigas Nakai extract showed the highest degree of preference among all the items of added Angelica gigas Nakai extract(color, odor, taste, hardness, crispness and overall quality) and the added Angelica gigas Nakai extract indicated possibilities for developments of Angelica gigas Nakai extract cookies.

This study was carried out to investigate the quality characteristics of pear jam containing fresh ginger(G1) and ginger powders; dried ginger powder(G2), freeze-dried ginger powder(G3), and hot-air dried ginger powder(G4). The moisture, crude protein, and crude ash content of the control group were significantly higher than those of the experimental groups (p<0.001, p<0.05, p<0.01). The pH of the dried ginger powder added jam(G2) was the lowest(p<0.05). Texture profile analysis found that the dried ginger powder added jam(G2) had the highest firmness, consistency, cohesiveness, and resistance to flow/viscosity among all samples(p<0.001). Regarding the spread-meter value of the pear jam, the control group (G1) and hot air-dried ginger powder added jam(G4) had the highest values. The dried ginger power added jam(G2) had the lowest value among the samples(p<0.01). Regarding the color values of the pear jam, the control group(G1) had the highest L and b values. Hot-air dried ginger powder added jam(G4), on the other hand, had the lowest(p<0.001). The opposite was true for a value: hot-air dried ginger powder added jam(G4) had the highest. From the sensory evaluation, a positive trend was observed for the appearance of the dried ginger powder added jam(G2)(p<0.001). For sweetness, the dried ginger powder added jam(G2) had the highest value. A positive trend was observed for the overall acceptability of the dried ginger powder-added jam(G2)(p<0.001). Therefore, the dried ginger powder-added sample(G2) seemed to be the most appropriate to make pear jam with high acceptability.
