  • 1. 1900년대 초기에는 조리 과학의 기초 개념으로 표준 recipe의 작성이 시도되었다. 2. 비타민과 무기질이 필수 영양소로 밝혀지면서 각종 식품 내의 영양가 분석이 광범위하게 이루어졌으며 과학 기술이 발달함에 따라 새로운 분석 기기의 도입으로 미량 원소의 분석도 가능하게 되었다. 3. 1950년대 후반부터 식품의 관능적 품질 요소를 평가하는대 Panel들의 오관을 이용한 관능 검사법이 이용되어 왔으며, 평가 방법이 점차 발달되어 IFT에서 1981년에 실험 목적에 따라 표준화된 관능조사 방법을 발표한 바 있다. 4. 식품의 품질 평가시 기계적 측정을 실시함으로써 객관적인 결과를 얻게 되었으며, 현재는 이를 관능 검사 결과와 관련시키고 있다. 5. 1970년대 이후 조리 과학적 측면에서의 식품 연구 경향을 J. Food Sci.와 Home Economics Research J.을 통하여 검토한 결과, 육류에 대한 연구가 가장 많았고, 영양가, 맛, tenderness가 주요 관점이었다. 그 다음으로는 두류와 곡류에 대한 연구가 많았으며 기타 식품에 대한 연구는 미흡한 실정이었다. 6. 미국에서 대두에 관한 연구는 동양에서의 이용방법을 직수입하지 않고 서구식 식생활에 맞게 발전시켰다. 이에는 textured vegetable protein등과 같이 육류 대체 식품으로서의 이용 가능성과 두류 단백질의 식품학적 기능성을 이용하여 첨가시 식품의 품질을 향상시키고자 하는 관점에서 연구가 진행되고 있으며 앞으로도 많은 관심을 받게 될 것으로 전망된다.

  • Studies were carried out to investigate physicochemical and gelatinization properties of legume, cereal and potato starches. Cowpea, mung bean, acorn, and buckwheat starches showed similar moisture content and amylose content, however, there is neither similarity nor certaion trend in WBC, swilling power, and solubility among them. DSC thermograms of cowpea, mung bean, acorn, and buckwheat starches showed similar patterns with two endothermic peaks and relatively broad gelatinization ranges. SEM photomicrography of gelatinized cowpea, mung bean, acorn and buckwheat starches showed highly swollen and extremely disintegrated, folded structure.

  • Seventy percent ethanolic extracts from commercially available 13 legumes were made to investigated their antioxidative activities by determining the reducing power, inhibitory effect on lipid peroxidation, scavenging activity against both superoxide radical and hydroxyl radical, together with inhibitory activity toward mitomycin C-induced oxidative damage of DNA. High level of reducing powers were detected in Yepat, Sokpiri, Yuweol-bean and Jeokdu. Inhibitory effects on lipid peroxidation were found ubiquitously in all extracts examined when employing the linoleic acid autoxidation system, whereas, only 3 legumes, Yepat, Namul-bean and Jeenuni-bean, were revealed marked inhibition in rabbit erythrocyte-ghost membrane lipid peroxidation system. Yepat, Namul-bean, Jeokdu and Jeenuni-bean showed great scavenging activities on superoxide radical, on the other hand, high level of hydroxyl radical scavenging activities were demonstrated in Sokpiri, Chungtae, Yepat and Jebi-bean. Ubiquitous inhibitory effects on mitomycin C-induced oxidative damage on DNA were found in all extracts tested, Among them, however, Yepat, Jeenuni-bean, Namul-bean, Nokdu and Jeokdu showed the higher level of inhibition. Taken together, we could assign Yepat, Jeokdu, Jeenuni-bean and Sokpiri, for the legume species highly functional on overall antioxidative activity.

  • 본 연구에서는 국의 영양소 구성의 다양성을 평가하고 국의 영양에 대하여 고찰하고 영양소 구성을 평가하는 방법에 대하여 고찰하였다. 국의 조리법에 관한 전문서적, 전문잡지 등으로부터 562가지의 국의 레시피를 수집하고 168가지의 전형적인 국의 레시피를 만들어 이를 기본 데이터로 하여 국의 열량 및 영양소를 분석하였다. 결과는 다음과 같다. 1. 168가지 국의 열량 및 영양소 함유량의 평균치를 보면, 한국인을 위항 영양권장량에 대한 충족률이 6.3%(열량)$\sim$41.3%(비타민A)의 범위에 이른다. 그리고 [밥과 국]만으로도 지방을 제외한 영양소를 한 끼 영양권장량의 50%이상 섭취할 수 있다. 국은 영양이 풍부한 음식임이 분명하다. 2. 영양소 구성의 다양성을 평가하기 위하여 한 끼 영양권장량의 50%이상 섭취할 수 있는 영양소의 구성을 살펴보았다. 영양소 구성의 다양성에 따르면 [밥과 국]의 82.8%가 '양호한 영양소 구성'이상이라고 평가되었다. 국은 훌륭한 영양소 구성을 가진 음식으로 평가한다. 3. [밥과 국]의 영양소 구성의 다양성과 국을 만드는데 쓰이는 식재료의 수, 종류, 중량과의 관계를 분석한 결과로부터 '양호한 영양소 구성'을 가진 국을 만드는 간단한 지침을 얻었다. 실제로 국을 만들 때 주로 쓰이는 식재료인 담색채소, 녹황색채소, 어패류, 육류, 두류 두제품 중에서 3가지를 100g 이상 되도록 준비하여 국을 만들면 '양호한 영양소 구성'을 가진 국을 만들 수 있다. 4. [밥과 국]의 영양소 구성의 다양성의 특징을 바탕으로 적절한 영양을 섭취할 수 있는 식사가 되기 위해 다른 반찬을 곁들이는 지침을 제안하였다. 국을 만들 때 $1\sim2$가지의 식재료를 이용한다면 영양소 구성의 다양성이 모자라기 쉽기 때문에 육류 어패류 난류 두류 반찬과 채소 반찬을 반드시 갖추어야 한다. 반면, 국의 식재료가 6이상이면 열량과 지방이 넘칠 수 있으므로 육류 어패류 난류 두류 반찬을 반드시 갖출 필요가 없다.

  • This study was conducted to determine the effect of pupal development and adult longevity of Spodoptera litura larvae reared on leaves of different leguminos plants of 11 varieties or cultivars. Pupal duration varied from 8.7 to 9.5 days depending upon different diets and duration of female pupa (8.3~9.1 days) was about 1 day shorter than that of male's (9.4~10.1 days). Prepupal an postpupal duration were 1.7 to 2.0 days and 6.7 to 7.7 days, respectively. Pupal weight ranged from 0.23g to 0.43g for female and 0.24g to 0.35 g for male. Percent change of pupal weight was lowest (11%) on geomjeongkong-1 and highest (16%) on bukwangkong. Adult longevity was in ranging from 7.8 days on dongbu to 11.2 days on bukwangkong and tended to become slightly longer in female than tin male. Significant relationships were recognized between moisture content of feeding leaf, the pupal duration and weight and adult longevity.

  • The contents of flatulence factors such as raffinose and stachyose were determined by two-dimensional thin-layer chromatography using a guide-strip technique for some legume seeds and soy products consumed in Korea. Raffinose contents in bean samples were 1.34% in domestic soybean, 1.17% in imported soybean, 0.65% in kidney bean, 0.49% in red bean and 0.49% in mung bean. Stachyose contents were 4.1% in doemstic soybean, 3.6% in imported soybean, 3.0% in kidney bean, 2.9% in red bean and 1.9% in mung bean. The flatulence factors were not detected in soy sauce whereas soy paste contained 46.6mg% of raffinose and none of stachyose. The contents of raffinose and stachyose were 26.7mg% and 53.7mg% in soy curd and 26.5mg% and 41.7mg%, respectively, in soy milk.

  • This study was conducted to determine the effect of food combinations of leguminous seeds on the nymphal development and adult fecundity of Riptortus clavatus Thunberg. Nymphal duration ranged from 20 to 28 days depending on food combinations with the shortest on the seed of soybean (Glycine max Linnaeus), soybean + kidney bean (Phaseolus vulgaris Linnaeus) and soybean + peanut (Archis hypogaea Linnaeus) and the longest on the seed of kidney bean. Instar duration was longer with increasing instar from 2.4 to 2.5 days in the 1st instar to 5.3 to 7.3 days in the 5th instar Accordingly, instar duration was significantly different on food combinations exception of 1 st instar Percent emergence varied from 3.5% on peanut to 65.0% on the seed of soybean + peanut. Nymphal mortality was the highest in the 1 st instar regardless of food combinations. Adult longevity was in range of 5.5 days to 11.2 days which was the shortest on the seed of kidney bean+peanut and the longest on soybean + peanut and was about 8.0 days on the other food combinations. Total number of eggs laid by female was most on soybean+peanut and was least on kidney bean + peanut. Accordingly, it can be recommended that food combination of the seed of soybean + peanut was the best and then was soybean only while other food communications of leguminous seeds was hard to use for mass rearing of R. clavatus.

  • Physicochemical characteristics and antioxidant activities of twelve varieties of legumes and cereals in Korea were analyzed and compared. Crude protein content was higher in legumes (20.60~34.47%) than in cereals (8.96~15.45%). Crude fat contents of soybean (17.73%) and black soybean (18.79%) were higher than other legumes (0.68~1.38%) and cereals (1.01~5.39%). The major minerals were potassium, calcium and sodium, and especially calcium and potassium were high in legumes. Unsaturated fatty acids composition ranged from 66.79% in cowpea to 85.14% in soybean, and $\Omega$-3 fatty acids (linolenic acid) content was higher of 7.47~48.25% in legumes than 0.36~3.71% in cereals. Total polyphenol content was higher 1.32~4.15 mg/g in 80% EtOH extracts from legumes than 0.53~2.83 mg/g in cereals. DPPH and ABTS radical scavenging activities were high values of 62.60% and 264.20 mg AA eq/g, respectively, in EtOH extract from sorghum.
