  • 젤라틴은 척추동물을 비롯하여 무척추동물의 뼈 또는 껍질에 널리 분포하는 생체 단백질인 콜라겐의 유도 단백질로서 식품용은 물론 사진용, 캡슐제재 등의 약용 및 공업용으로 그 활용 범위가 매우 넓은 천연 단백질이다. 즉 젤라틴은 안전성이 극히 높은 식품소재로서 열가역적이면서 보수성, 콜로이드성 및 기포성 등과 같은 성질이 우수하기 때문에 젤리, 제과 및 제빵용, 유화제, 조미료, 육가공품의 품질 개량제, chewing gum의 base, 청주나 과즙 쥬스의 청징제 및 피복용 등 그 용도가 광범위하다. (중략)

  • 젤라틴은 일반적으로 콜라겐의 가수 분해로 생성되어지는 단백질로서 대부분 동물의 결합 조직이나 피부, 배에 존재한다. 젤라틴은 젤리, 제빵 및 제과, 유화제 및 chewing gum base 등과 같은 식품용은 물론이고, 의약용, 사진용, 미생물 배양용 등으로도 사용되어 지고 있다. 젤라틴은 대부분 돼지나 소와 같은 육상 동물에서 얻어지고 있으나 최근 들어 광우병과 구제역과 같은 안전상의 문제가 대두되는 시점에서 그들의 대체 원료가 필요로 하게 되었고 이들을 대신하기 위해 어류에서 추출한 젤라틴에 많은 관심을 보이고 있다.

  • End-use properties of 26 Korean wheat cultivars (KWC) were evaluated to assess consumer satisfaction with 6 imported wheat and 5 commercial wheat flours. In end-use quality testing of cooked noodles, Absorption of noodle dough sheet of ASW (Australian standard white) was similar to Anbaek, Eunpa, Gobun, Hanbaek, Jeokjoong, Jonong, Namhae, and Sukang. Thickness of noodle dough sheet of KWC was showed thin difference. In imported wheat and commercial flour, Commercial flour for baking cookie (Com5) with lower protein flour was lower than those flours. In lightness of prepared noodle dough sheet, Lightness value ($L^*$) of KWC was lower than those of Commercial flour for making white salted noodle (Com1), commercial flour for making for yellow alkaline noodle (Com2), and commercial flour for multi-purpose (Com4). Lightness value ($L^*$) showed significantly negative correlations with particle size of flour, ash, damaged starch, and protein content. Hardness of cooked noodles positively correlated with protein content. In texture of cooked noodles, Hardness of Com1 was similar to that of Alchan, Dahong, Jeokjoon, and Sukang. Also, hardness of Com2 was similar to that of Gobun, Jokyung, Jonong, Keumkang, and Namhae. In end-use quality of bread, bread loaf volume of commercial flour for making bread (Com3) was similar to Alchan, Jokyung, Keumkang, and Namhae but firmness was low. Bread volume showed better relationships with higher SDS-sedimentation volume, longer mixing time of mixograph, higher height of dough during development. Firmness of crumb was negatively correlated with bread volume. Diameter of cookie showed significantly negative correlations with particle size of flour, damaged starch, and protein content. Also, Top gain score became higher as the increase diameter of cookie. In end-use quality testing of cooked cookie, Cookie diameter of Com5 was similar to that of Dahong, Geuru, Olgeuru, Tapdong, and Uri but top grain was low.

  • Protein content and amino acid composition of three prospective Korean wheat varieties (Youngkwang, Wonkwang and Chokwang) were studied from the viewpoint of baking performance. 1. Protein contents of Korean varieties were Less than 10% which were relatively lower than the U. S. baking standard. These levels were considered insuffcient for best baking performance. 2. Compared to U. S. baking standard, Korean wheat varieties showed slightly lower level of glutamic acid, which is considered to play an important role in baking performance of flour. Approximately 25% decrease in glutamic acid content was observed in Korean varieties when the absolute amount of glutamic acid per unit sample size was compared. 3. Korean wheat varieties showed similar levels of proline and cystine, slightly higher levels of lysine, ammonia and aspartic acid; and slightly lower level of essential amino acids compared to the U. S. baking standard. 4. Protein content and amino acid composition of Korean wheat varieties were considered to be intermediate of U. S. baking and cookie standards. From this viewpoint, Youngkwang showed the greatest potential for best baking performance among Korean varieties.

  • Leading enterprises in contract farming are in control of agricultural production and influence the structure of the agricultural system in contract areas. This study focuses on the contract farming of potatoes for manufacturing chips, which uses a high proportion of domestic raw materials, and identifies the characteristics of contract farming between confectionery company 𐩒 and potato farms in Haean-myeon, Yanggu-gun, Gangwon-do. This study also analyzes the impact of contract farming on local agriculture from the perspective of the industrialization of agriculture. The results of this study demonstrated that contracting companies ensured the quality of potatoes and smooth agricultural operations by first preferentially selecting farmhouses with land that is easy to work with and then supplying the necessary agricultural machinery to promote the intensification of their work. In addition, contracting companies influenced the centralization of the agriculture sector by selecting farmhouses capable of contracting over a certain scale and guaranteeing them sales channels and the specialization of potato farming in contract areas, mainly through the supply of processing varieties and the spread of cultivation technology. The results confirmed that these three dimensions of contract farming promoted the industrialization of local agriculture.

  • This study was conducted to develop effective manufacturing methods of a total mixed ration(TMR) composed of broiler litter(BL) and bakery by-product(BB) for ruminants. Five experiments included a small-scaled manufacture of TMR using a deepstacking method(Exp. 1), its pelletization(Exp. 2), its field-scaled manufacture(Exp. 3), a field-scaled manufacture using an ensiling method(Exp. 4), and a mixing process of deepstacked BL and BB prior to feeding(Exp. 5). BL and BB were mixed at a ratio which makes total digestible nutrients of the TMR 69%. For each experiment, temperature, appearance and physico-chemical properties were recorded and analyzed. The chemical composition data revealed that the mixture of BL and BB showed nutritionally additive balance which resulted from a considerable increase(P<0.05) of organic matter and a desirable decrease(P<0.05) of protein and fiber up to the requirement level for growing ‘Hanwoo’ steers. Deepstacking of BL and BB in Exp. 1 and 3 resulted in a sufficient increase of stack temperature for pasteurization, little chemical losses, appearance of white fungi on the surface, and partial charring due to excess stack temperature. For Exp. 2, its pelleting, which was successful using a simple, small-scaled pelletizer, resulted in a little loss(P<0.05) of organic matter and an increase(P<0.05) of indigestible protein(ADF-CP). Ensiling the mixture in Exp. 4 made little effect on chemical composition; however, one month of the ensiling period was not enough for favorable silage parameters. Deepstacking BL alone in Exp. 5 tended(P<0.1) to decrease true protein : NPN ratio and hemicellulose content and increase ADF-CP content due to the heat damage occurred. Deepstacking or ensiling of BL-BB mixtures and simple incorporating of BB into deepstacked BL prior to feeding could be practical and nutrients-preservative methods in TMR manufacture for beef cattle, although ensiling needed further hygienic evaluation.

  • 'Morningpurple' is a new sweetpotato variety developed by Mokpo Experiment Station, National Institute of Crop Science (NICS), RDA in 2007, for flowering. This variety was selected from the cross between Sinchunmi and Hi-dry in 2004, seedling and line selections were practiced from 2005 to 2006. 'Morningpurple' has morning glory type flowers with purple color. It has triangular leaf, green with purple vine and petiole, elliptic storage root, red skin and yellow flesh color of storage root. The average yield of storage root was 15.0 ton/ha. Number of storage roots over 50 gram per plant was 2.6, and the average weight of storage root was 143 gram.
