'자영'은 2003년 '대서' 품종과 AG34314 계통 간의 교잡 후대에서 유래되었으며, 국립식량과학원 고령지농업연구센터의 감자육종 프로그램을 거쳐 선발되었다. 2006년과 2007년 대관1-104호라는 계통명으로 지역적응시험을 수행하여 주요 생육특성, 괴경특성, 수량성 및 병해특성을 검토하였으며, 2007년 '자영'으로 명명하여 국립종자관리원에 신품종으로 출원하였다. '자영' 감자는 모양이 비교적 둥글고 눈이 얕으며 껍질과 속이 모두 자주색이다. ha당 평균 수량은 37.4톤이었고 봄재배에서 가장 높은 수량성을 나타냈다. '자영'은 감자더뎅이병과 잎말림바이러스병에 높은 저항성을 나타내었으나, 역병에는 감수성이었다. 건물함량은 비교적 높은 20.3%로서 칩가공용으로도 적합하였다. 안토시아닌 함량은 가을재배에서 가장 높은 43.7 mg/100 g이었고, 작형별 평균 함량은 '자심' 품종보다 4.7배 정도 더 많았다.

The study was aimed to estimate the degree of recognition of, satisfaction with and needs for cooking practice education. 300 female students of middle schools and high schools in Seoul, Kyung-gi, Inchon area were targeted fer the research, which has been conducted from January 1st to December 20th in 2003. The crosstab, the t-test, and the ANOVA analysis were processed as methods using SPSS. The study showed that most of students had experienced cooking exercises, and the degree of satisfaction of the high school group was higher than that of the middle school group. Both groups answered they wanted more time for the cooking practice classes and the middle school group had the greater necessity. The necessity far practice lessons of cooking traditional foods reaches n high level in both groups, All the students answered they liked both western and traditional foods, but preferred the traditional food to the western one. They also believed the traditional food was more healthy than the western one. In terms of the needs for cooking practice education, the middle school group wanted to learn how to cook cake, pie, steak potato chip, and hamburger, while the high school group wanted cake, pie, steak sandwich, and potato chip. As for the traditional food, the middle school group wanted to learn how to cook Naegmyun(cold noodles), fried rice, rice hash, dumpling soup, and knife-cut noodles. The high school group, however, picked knife-cut noodles, fried rice, iced noodles, rice hash, and rice-cake soup.

본 연구에서는 Bacillus sp.를 이용하여 감자슬라이스를 발효시킨 후 성분을 분석하고, 감자 칩으로 가공하여 색도와 아크릴아마이드 함량을 알아보았다. B. licheniformis, B. methylotrophicus, B. subtilis 각각을 $7.5{\times}10^7{\sim}2.7{\times}10^8CFU/mL$ 접종하여 6시간 동안 발효한 결과 균수의 증가는 보이지 않는 유도기였음에도 불구하고 총당 함량은 감소하였으며, 환원당 함량 변화에 영향을 미쳤다. 감자 칩의 색도는 대조구에 비하여 실험구의 L 값이 증가하였으며, a 값과 b 값은 감소하여 감자 칩으로 적합한 색도를 나타내었다. 발효 감자 칩의 아크릴아마이드 함량은 평균 약 94% 감소하였다.

The experiments were carried out in open experimental field of Field Crops Research Institute, Hai Duong, Vietnam in Winter Spring seasons 2015-2016 and 2016-2017 for finding high yielding of Korean chipping potato varieties which are adaptable to Vietnam condition. Six varieties of Korean potato (G1, G2, G4, G10, B1, B2) were experimented. The control variety (G6) was Atlantic which has long been a standard chip variety. The results showed that, for a hill, there was positive correlation between number of stems and number of tubers. The hill yield also showed highly relation to the plant height and number of tubers. Even though the growth and yield of potatoes grown in the season 2016-2017 were significant higher than these of potatoes grown in the season 2015-2016, their percentages of tubers infected by scab disease were much higher. This is probably because of irregular soil moisture content at the tuber forming duration. While G1, G6 and B1 are white flesh varieties, the remaining are yellow flesh varieties. There are two shapes types among experimented varieties: oblong (G1, G10, B1) and round shape (G2, G4, G6, B2). The total yields of varieties G1, G2, B1, B2 were higher than the total yield of the control variety from 16.5-49.4% in the season 2015-2016 and from 39.8-75.6% in the season 2016-2017.

In this study, the acrylamide contents of foods were estimated via liquid chromatography (LC)/mass spectrometry (MS)/MS after the food matrix constituents had been degraded with digestive enzymes (i.e., pepsin and pancreatin) and extracted with water. The quantities of acrylamide released from samples of cereal, potato chips, peanuts, and coffee were $62{\pm}5.1,\;970,\;106{\pm}20$, and 890 ppb, respectively. No acrylamide was detected in samples of soybean curd (tofu), fish cake, and ham. Compared to the amounts of acrylamide detected after extraction with water only, we noted no significant differences in the soybean curd, fish cake, potato chip, ham, and coffee samples. However, the quantities of acrylamide released from the cereal and peanut samples were approximately 2-fold larger following pretreatment with the digestive enzymes. This study presents a new in vitro enzymatic digestion method which allows for a more accurate estimation of the acrylamide contents of foods.

본 연구는 콜드칩 가공용 감자 계통을 선발하고자, 47계통과 대조구 품종인 '대서', '수미', '구이벨리'의 수확 후, $4^{\circ}C$, $8^{\circ}C$ 저온저장 및 $20^{\circ}C$ 가온 조정처리에 따른 glucose 함량, 아크릴아마이드 함량 및 두 형질 간의 상관성을 비교 분석하였다. 대조구 품종 및 47계통 모두에서 수확 후, glucose 함량이 0.25% 이하, 아크릴아마이드 함량 1000ppb 이하로 나타났고, $4^{\circ}C$ 저온저장에 의해 glucose와 아크릴아마이드 함량 모두 급격히 증가하였으며, H7, H13, H16, H40 등 4계통에서만 500ppb 이하로 검출되었다. $8^{\circ}C$ 저온저장 역시 두 함량 모두 증가하였으나, $4^{\circ}C$ 저온저장에 비해 비교적 낮게 나타났으며, $20^{\circ}C$ 가온 조정에 의해서도 두 함량 모두 감소한 것으로 나타났다. 저온저장에 따른 glucose 함량과 아크릴아마이드 함량 간의 상호관계를 분석한 결과 정의 상관성을 확인할 수 있었다. 결론적으로 저온처리에도 낮은 glucose 함량을 나타낸 H7, H13, H16, H40계통들이 낮은 함량의 아트릴아마이드 함유한 것으로 나타나 콜드 칩 가공용 우수 감자 계통으로 선발할 수 있었다.

The objective of this study was to determine the degradability of cassava chip (CC), cassava waste (CW), yellow sweet potato (YP), white sweet potato (WP), purple sweet potato (PP), corn meal (CM), and rice bran (RB) using in situ technique. Two ruminally fistulated steers with an average weight of $303{\pm}10kg$ were used to determine in situ degradabilities of DM and OM. Seven feed sources were weighted in nylon bags ($38{\mu}m$ pore size) and incubated ruminally for 1, 2, 4, 6, 8, 12, 24, and 48 h. The results showed that asymptote (a+b) and effective degradability (ED) of DM of energy sources ranked from the highest to the lowest; CC, YP, WP, PP, RB, CW, and CM (99.3, 92.5; 97.6, 87.9; 97.5, 87.9; 97.2, 87.8; 87.5, 63.6; 78.6, 63.0 and 81.7; 59.3, respectively) and for OM asymptote (a+b) and effective degradability (ED) were similar to those of degradation of DM (99.4, 93.4; 98.8, 89.8; 98.5, 89.4; 98.4, 88.1; 92.4, 65.8; 85.1, 66.9 and 83.6, 63.3, respectively). It was concluded that disappearance characteristic of CC was the highest and it may potentially facilitate the achievement of optimal ruminal availability of energy: protein especially with NPN for microbial protein synthesis.

실험실에서 제조한 동백유의 몇가지 이화학적 특성은 요오드가가 78.2로 나타나 불건성유로 분류되었고, 지방산 조성은 Oleic acid가 총 지방산함량 중 84.7%를 차지하여 Mono unsaturated fatty acid의 함량이 매우 높은 기름으로 측정되었다. 40$\pm$5$^{\circ}C$의 항온저장시 산화안정성은 동백유가 대두유에 비해 과산화물가와 산가 측정에서 모두 저장 안정성이 높은 것으로 비교되었다. 180$\pm$5$^{\circ}C$에서 튀김시의 동백유 시료의 산가는 튀긴 횟수의 증가에 따라 대두유 시료와 별 차이 없이 모두 점진적으로 증가하였으나 요오드가의 변화는 동백유 시료에 비해 대두유 시료가 2배 이상 감소된 것으로 나타났다. 동백유, 대두유, 옥배유로 튀긴 Potato chips의 관능평가는 맛, 색, 냄새 등의 종합적인 기호도 측정에서 시료간의 유의적인 차이가 5% 수준에서 인정되었으며, 동백유의 튀김시료가 가장 선호도가 높은 것으로 나타났다.

The stability of red pepper seed oils during storage at 20${\pm}$3$^{\circ}C$, 40${\pm}$3$^{\circ}C$ and heating at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$ were measured to evaluate red pepper seed oil as a cooking oil. Two species of red pepper seeds (native, improved) were dried by either sunlight or heating to prepare the oil samples of NS (native, sunlight-dried), IS (improved, sunlight-dried), NF (native, heated), and IF (improved, heated). During storage at 20${\pm}$3$^{\circ}C$ or 40${\pm}$ 3$^{\circ}C$, acid values (AV) of all red pepper seed oils were higher than that of soy bean oil (SBO), however, peroxide values (POV) were similar to SBO. Antioxidative stability of NS was better than SBO but IF was not. By the heat treatments at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$, NS was identified to have better antioxidative stability than SBO and IF was the lowest. In sensory evaluation of each deep-fat fried potato-chip at 180${\pm}$5$^{\circ}C$, potato-chips fried in NS were better than that of SBO for color, taste, and flavor. NS-fried potato-chips got the highest score in overall acceptance (p<0.05), however, those of IF showed little acceptance. When blended oils (SBO: NOS, 0, 25, 50, 75%) were used, 50% blended oil was the best for taste, color, flavor, cripness, and total acceptance.
