  • 이 연구는 식품영양학의 학문적 특성과 문헌분류 체계를 분석한 후, 이를 토대로 KDC 식품영양학의 분류체계를 개선할 수 있는 방안을 제시하고자 시도되었다. 이 연구결과를 요약하면 아래와 같다. 첫째, 식품영양학의 학문분류는 대체로 영양학, 식품학, 급식경영학의 3개영역으로 구분되어 있으며, 한국학술진흥재단의 연구분류표에서도 이와 유사하게 구분되어 있다. 둘째, 식품영양학의 문헌분류 체계에서는 학문분류 체계와는 달리 대체로 영양학과 식품학이 별개의 학문으로 구분되어 있다. 즉, 영양학은 의학의 하위학문으로, 식품학은 가정학의 하위학문으로 배치되어 있으며, 식품학에서 급식경영학을 함께 다루고 있다. 셋째, KDC 식품영양학의 분류체계는 DDC나 NDC와 같이 영양학과 식품학이 별개의 학문으로 구분되어 있지만, 실제로는 분류하는 사람에 따라 혼란을 일으키고 있다. 그리고 일부 항목은 학문발전의 추세에 부응하지 못하고 있거나 한글 및 영문표기의 오류가 나타나고 있다. 따라서 이러한 문제점을 해결하기 위해 영양학과 식품학의 분류혼란은 해당 항목에 주기를 첨가하여 혼란을 최소화할 수 있도록 하였으며, 학문발전의 추세를 반영하여 급식경영 관련 항목 및 한방요리 등과 같은 새로운 주제를 추가하거나 현대적인 용어로 대치하여 수정 전개방안을 제시하였다.

  • To enhance the efficacy of Abeliophyllum distichum leaves, extracts were prepared using different solvents for hydrolytic enzyme-treated Abeliophyllum distichum leaves. Physicochemical quality and antioxidant activity were measured. Soluble solids, reducing sugar, ascorbic acid, flavonoids, and polyphenols contents showed the lowest values in the control without enzyme treatment. However, they showed high contents in ethanol extract. In the case of enzyme treatment, their values were higher than those of the control. In particular, verbascoside content increased about 220 times more than that of the control group when treated with enzymes and extracted with 50% ethanol. pH was lowered upon enzymatic treatment. Regarding DPPH radical scavenging activity, for enzyme-free, 25% ethanol extract showed the highest activity among extracts with different solvents. For cellulase and pectinase-treated leaves, water extract showed the highest DPPH radical scavenging activity among extracts with different solvents. For leaves treated with enzyme combination, 50% ethanol extract showed the highest DPPH radical scavenging activity among extracts with different solvents. Regarding ABTS radical scavenging activity, it was generally higher in the 50% ethanol extract than in the water extract and 25% ethanol extract. In particular, verbascoside content was increased when the extract was prepared by co-treatment with enzymes and 50% ethanol.

  • This purpose of this study was to develop a functional muffin by adding yam powder in the shape of a muffin as a partial surrogate for wheat flour. The yam has been found to be effective for liver and kidney function, as well as the digestion of protein, since it produces glucuronic acid in the body. Therefore, the purpose of this study was to determine the optimal mixing conditions of yam muffins by adjusting the amounts yam powder, butter, and sugar. The mixing conditions for the yam muffins included 3 categories: yam powder $(X_1)$, sugar $(X_2)$, and butter $(X_3)$ by Central Composite Design (CCD) which was optimized by Response Surface Methodology (RSM). The effects of the three variable additions on muffin quality were examined via physical and chemical experiments, such as the analysis of texture (hardness, cohesiveness, springiness, gumminess), coloration (lightness, redness, yellowness), and height. Lastly, we performed a sensory test, which revealed significant findings for gumminess, color, appearance, flavor, softness (p<0.05), redness, and overall quality (p<0.01). Consequently, the optimal mixing rate which best satisfied the sensory items were 34.35g of yam powder, 80.15 g of sugar, and 80.55 g of butter.

  • The purpose of this study was to investigate the effect of shrimp flour on quality characteristics of dumpling shell. Dumpling shell samples were prepared with wheat flour along with the addition of different amount of shrimp flour, followed by functional measurements and sensory evaluations. According to amylograph data, the composite shrimp flour/wheat flour samples had increased gelatinization temperature with increasing shrimp flour content, while initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity were reduced. In terms of color values, L value decreased, but a and b values increased with increasing shrimp flour content. Furthermore, the addition of shrimp flour increased hardness and decreased chewiness in all samples. Overall, sensory evaluations proved that dumpling shell with 10% added shrimp flour was preferred over the other samples.

  • To confirm the applicability of crab apple, the composition and content of amino acids and minerals with 'Fuji' apple were measured. Apple and crab apple were extracted with water, 70% and 100% ethanol, respectively. The contents of polyphenols, flavonoids, and ascorbic acid, antioxidant activities of these extracts were measured. The amino acid composition of apples comprised a total of 17 amino acids. The total amino acid contents of apple and crab apple were 2,050.45 mg/kg and 900.05 mg/kg, respectively. For minerals, the total mineral content of apple and crab apple were 489.14 mg%, 529.77 mg%, respectively. The contents of polyphenols, flavonoids, and ascorbic acid of apple and crab apple extracts were highest in 70% ethanol extracts. The content of polyphenols, the crab apple extract, showed a generally higher content than the apple extract. The content of flavonoids, apple and crab apple extracts revealed no difference between extracts. The content of ascorbic acid, apple extract showed a generally higher content than the crab apple extract, but there was no significant difference between extracts. In the case of DPPH and ABTS radical scavenging abilities, 70% ethanol extract showed the highest antioxidant activity, and crab apple showed higher activity than apple extracts.

  • To improve the shelf-life of Centella asiatica, Centella asiatica was treated with gel packs containing slow-released chlorine dioxide (ClO2) gas at 3-5 ppm for 20 days at 4℃. The weight loss rate, as well as the changes in pH, color, and texture of the treated samples, were investigated. The weight of the control and ClO2 gas-treated samples was decreased during the storage period. The change in weight of the control was slightly faster than that of the samples treated with 3 and 4 ppm ClO2 gas. The pH of the control and the ClO2 gas treated samples were decreased during the storage period and there was no significant difference between the control and ClO2 gas treated samples. Concerning color (lightness, redness, and yellowness) changes of Centella asiatica during the storage period, there was no significant difference between the control and ClO2 gas treated samples. The change in shear force in the leaf and stem of Centella asiatica during the storage period was slightly lower in the 4 ppm ClO2 gas treated samples (in the leaf) compared to the control and 3 and 4 ppm ClO2 gas treated samples (in the stem) compared to the control and 5 ppm ClO2 gas treated sample.

  • The purpose of this study was to analyse factors related to Home Meal Replacement (HMR) use among university students and to determine the dietary quality according to its consumption. A survey on the consumption of HMR and Nutrition Quotient (NQ) was conducted from September to November 2021. The study included 232 university students (88 males, 144 females) from Chungcheong. The proportion of consumption at least once a week was 71.55% for ready-to-eat foods, 55.60% for ready-to-cook foods, 40.95% for fresh-cut products, and 21.12% for meal-kits. The preference ratings were as follows: ready-to-eat foods, 3.77 out of 5 points, meal-kits, 3.53 points, fresh-cut products, 3.52 points, and ready-to-cook foods, 3.45 points. In terms of satisfaction, convenience (4.06 out of 5 points), taste (3.71 points), variety (3.67 points), and food hygiene (3.62 points) were rated the highest. The scores in the moderation NQ were significantly lower in the groups that consumed ready-to-eat foods (p=0.0002), ready-to-cook foods (p=0.0002), and meal-kits (p=0.0068) at least once a week compared to the groups that consumed them less than once a week. In conclusion, the results will serve as basic data for nutrition education for proper consumption of HMR among university students.
