  • This study was conducted to find out the proper ways of implementation of Hazard Analysis Critical Control Point (HACCP) concepts applicable to the current Korean food inspection system. The following recommendations are based on an in-depth review of the Canadian Food Safety Enhancement Program (FSEP), which is one of the leading HACCP programs adapted to the food industry. Since 1997, the HACCP system has been voluntarily applied to meat processing plants in Korea in accordance with the Food Protection Law. But the guidelines are obscure and inadequate to expand to the diversity of food plants, and are therefore only applied to a limited number of plants of small scale enterprise. For these reasons, it is necessary to prepare an enhanced food safety control program focused not only on the HACCP plants but also on the non-HACCP plants. The national program should be the fundamental framework of a food safety control policy enforced by all the relevant authorities. The Prerequiste Program of Canadian Food Inspection Agency and Sanitation Standard Operating Procedures (SSOP) of FSIS are good example programs for the non-HACCP plants. These programs, which are a major part of the HACCP system, could easily be adapted to the Korean food industry. To improve the current HACCP implementation guideline, it is necessary to develop a detailed implementation manual, generic HACCP model, training program, and an audit program.

  • Gu-Hwang Plants(plants collected from mountains and fields and eaten when no food was available) is healthy, life saving food material, being Mi(taste) and Ki(energy) of nature, for modern people who lose their health by oversupplying energy and unbalanced diet. Also, Gu-Hwang Plants is material for new medicine and functional foods. However, there is a lack of document research about Gu-Hwang plants in Korea. "Gu-Hwang-Bon-Cho" is a book about plants written as a guide for collecting food from nature and maintaining life at times when no food is available due to natural disaster. The book describes in which soils the plants are produced and the names for the plants, and classifies them according to hot and cold characters and sweet and bitter tastes of the plants. In addition, the book distinguished plants' edible parts, such as flower, fruit, root, stem, peel, and leaf, with how to collect and cook them. The book is of great value that it is reprinted over generations and now there are 30 kinds of existing books. This study conducted research based on books published throughout history which are the first book of this kind by Ju-wang-ju, a book published in 1525 by I-Ryeom, a book published in 1555 by Youk-gan, a book published by Ho-seung of Sa-cheon, and a book published in 1566 by Ju-gon.

  • The first historical record on the use of wild edible plants as foods in Korea involves sswuk and manul concerned with the mythology of Tangun. Numerous names of wild vegetables had been recorded in various ancient books. Wild edible plants are of great value as food resources and for domestication, since they have variable edible portions and quite a long picking season. Several kinds of wild edible plants have been already grown as vegetable crops. Doragi (Platycodon grandiflorum) is probably the one with the longest history of cultivation. During World War II, an attempt had been made to substitute vegetable crops for wild edible plants. As picking wild greens requires a great deal of labor and plants of wild growth are limited in the amount, domestication of wild vegetables as crops appears to be an urgent need for securing food resources in Korea.

  • Vitamin U levels in 26 kinds of food plants are well known to healthy vegetables in Asian or Western countries were determined. Spinach showed the highest level of 452.04 mg/kg and in order Pack-choi (343.18 mg/kg) > Kale (234.18 mg/kg) > Somssukbujaengi (197.66 mg/kg) > leaf mustard (196.21 mg/kg) > aralia bud (192.50 mg/kg)> broccoli (189.03 mg/kg) >Asparagus (187.35 mg/kg). Among Korean wild medicinal plants, Sumssukbujaengi showed the highest value followed by Sanmanul (a kind of wild garlic) level of 143.46 mg/kg. For Chinese cabbages and cabbages, vitamin U showed different levels according to the parts of plant such as core, middle, outward leaves. In both samples, middle parts of leaves including midribs contained the highest level of vitamin U. The level of vitamin U was dependent on the part of the plant sample and cultivars. Leaf parts of turnip and white radish showed higher value of 84.82 mg/kg and 124.62 mg/kg than those of roots which were in order of middle (112.39 mg/kg), top (84.84 mg/kg) and bottom (84.61 mg/kg) portions in the white radish. In the analysis of amino acids, we didn't find either distinctive relationship between methionine and vitamin U synthesis or significant connection various free amino acids and vitamin U level in food plants.

  • This research analyzed emergency foods in Korea during the Japanese occupation through the food literature of that era, and attempted to determine the cultural history of food through recorded contents of emergency foods literature. The examination was mainly conducted on the basis of the four excerpts within the emergency foods literature of the Japanese occupation: "Emergency plants of the Joseon", "Wild Fruits and Plants of the Joseon", "Guhwangginam", and "Emergency Plants and How to Eat of the Joseon". After a thorough examination, each of the excerpts had unique data regarding amounts of ingredients, such as Namuls, trees, grain, and beans. "Emergency Plants of the Joseon" listed 142 Namuls, 54 trees,"Wild Fruits and Plants of the Joseon" listed 32 Namuls, 29 trees, "Guhwangginam" 4 grains, 205 Namuls, 84 trees, "Emergency Plants and How to Eat of the Joseon" listed five grain, three beans, 37 Namuls, and eight trees. Emergency foods literature demonstrated the utilization of various wild and edible plants as excellent ingredients for meals. Additionally, changes in traditional cooking methods using sugar, preservation through canning, and frying substantiate the subtle influence of foreign influence on Korean food. Perhaps the carefully structured components of the Korean food can be interpreted as a direct result of a scientific approach. It can be argued that creative application of methods ingredients, approach, of emergency foods is necessary to this modern age.

  • We screened the methanol extracts from 133 plant species growing in Korea for antimicrobial activity against enterohemorrhagic Escherichia coli 0157 : H7. Those are selected from three plant grouping ; traditional medicinal herbs, edible plants, and flowers. They were tested by disk diffusion assay. From evaluation of the inhibition zone diameter of microbial growth, we found that the flower extract of Rhododendron Schilpenbachii Max had the most significant antimicrobial activity against this bacteria. Extracts from most of the vegetables and plants did not show antimicrobial activity except for the leaves of Ginkgo biloba L. and seeds of Prunus Dallicina L. did not show antimicrobial activity except for the leaves of Ginkgo biloba L. and the seeds of Prunus sallicina L.

  • Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, and Portulaca) of edible plants and the effect of the processing on cyanide concentration. Total cyanide content was measured by ion chromatography following acid hydrolysis and distillation. Kernels of Prunus genus are used medicinally, but they possess the highest level of total cyanide of up to 2259.81 $CN^-$/g dry weight. Trace amounts of cyanogenic compounds were detected in foodstuffs such as mungbeans and bamboo shoots. Currently, except for the WHO guideline for cassava, there is no global standard for the allowed amount of cyanogenic compounds in foodstuffs. However, our data emphasize the need for the guidelines if plants containing cyanogenic glycosidesare to be developed as dietary supplements.

  • This study evaluates on students' understanding and misunderstanding of homeostasis, classification of animals and plants, and food production in plants, and analyzes the teacher factor as a possible source of students' misconception. A total number of 863 students and 47 biology teachers at the middle and high school were randomly selected. Students' conceptions and misconceptions were measured with concept evaluation statements (CES) which was translated into Korean by author. The CES was developed and validated by Simson and Marek (1988). Teacher's misconceptions were investigated the way in which teachers marked students' work. The supposed answer given to the teachers to mark was based on misconceptions held by students tested in concept evaluation statements. The results of this study are as follows : 1. 0% of 7th Grade students, 4.5% of 9th Grade students and 5.4% of 11th Grade students understood homeostasis. There was a significant difference at the level of students' understanding of homeostasis according to schools and gender(P<0.05). Many students had a tendency of understanding the conception of the homeostasis by experiences and unscientific use of everyday language rather than a scientific concept. 2. 0.4% of 7th Grade students, 3.1% of 9th Grade students and 2.9% of 11th Grade students understood classification of animals and plants. There was a significant difference at the level of students' understanding of classification of animals and plants according to schools and gender(P<0.05). Students classified animals and plants through personal experiences and observations instead of trying to classify through microscopic analysis of animals and plants cell. 3. 1.2% of 7th Grade students, 10.3% of 9th Grade students and 19.4% of 11th Grade students understood food production in plants. There was a significant difference at the level of students' understanding of food production in plants according to schools and gender(P<0.05). Students had a misconception that food production in plants was done by an absorption of nutrients from soil not by photosynthesis. 4. A large proportion of teachers surveyed in this study appear to have misconceptions about homeostasis (38.1%), classification of animals and plants (34.1%), food production in plants (40.4%). The male teachers had. more misconceptions than female teachers(P<0.05). However, they didn't show any significant differences according to schools and teaching experience(P<0.05). 5. According to the investigation of teachers' perception, 29.8% of the teachers acknowledged that they might be a cause for students' misconceptions. This study shows that 38.3% of teachers did not understand the analyzed biological concepts precisely. By comparing the data of students and teachers, it turned out that teachers participate in the students' misconceptions. And teachers themselves acknowledged that students' misconceptions could be caused by them. Therefore. teachers' right understanding of fundamental biological concepts should precede to students' biology education. New training programs for biology teachers seem to be urgent.
