The origin of Korean traditional food's spicy taste dates back to the first telling of the Dangun myth-a story of a tiger and bear who tried to reincarnate themselves in human form by eating garlic and wormwood. For a long time, Koreans have eaten spicy vegetables such as green onion, garlic, ginger, mustard, leeks, corni, cinnamon bark, and Chinese peppers (Zanthoxylum schinfolium) and Zanthoxylum bungeanum. In prehistoric times, spicy vegetables were probably used to eliminate the smell of meat. In the agricultural age, they were used to supplement meals with fresh taste. They were also used as a substitute for salt (salt was very precious and expensive) as well as side dishes for the poor. Spicy vegetables have also been used as a substitute for main dish like medicinal gruel and used to increase the spiciness of soup, and they are usually used as a side dish and with condiments in namul (cooked vegetable dishes), sangchae (salad), ssam (wrapped in greens and garnished with red-pepper paste or other condiments) and Kimchi. In addition, chili pepper was introduced to the Korean Peninsula in the middle of the Joseon Dynasty (mid-15th, 16th century). The soil and climate of the Korean Peninsula are suitable to growing chili pepper, and chili pepper has excellent adaptability and productivity. Accordingly, it is processed to red pepper powder and has become a major part of traditional Korean food along with Chinese pepper. Since the Joseon Dynasty, many kinds of Kimchi made with red pepper powder have been developed, and most Koreans enjoy them these days. The main characteristics of Korean food are spiciness and honest-to-goodness taste.

Objective: The effect of pre-converted nitrites from natural sources (spinach, lettuce, celery, and red beet) on color development in raw and cooked pork sausage was investigated in this study. Methods: The pork sausage was manufactured with six treatments: NC (negative control, nitrite free), PC (positive control, 150 ppm sodium nitrite), FS (3.0% fermented spinach extracts), FL (3.0% fermented lettuce extracts), FC (3.0% fermented celery extracts), and FR (3.0% fermented red beet extracts). Results: The pH value of the pre-converted nitrites groups was lower than those treated with 150 ppm sodium nitrite (p<0.05). The color values of raw and cooked pork sausage added with pre-converted nitrite showed slightly lower and/or similar lightness, lower redness, and higher yellowness values than PC. Color development (redness values) of cooked samples added with FS was higher than those of the NC and other treatments (FL, FC, and FR). Additionally, treatments with FS and FL were most effective for reducing thiobarbituric acid reactive substances and volatile basic nitrogen than the NC. Conclusion: Effects of natural nitrites from fermented vegetables on shelf stability of raw and cooked pork sausages were investigated. Fermented spinach extract was much more useful for maintaining the color development, but also inhibiting lipid and protein oxidation of cooked pork sausage. Therefore, pre-converted nitrite from spinach as a natural nitrite could be used as another natural nitrite source for making processed meat products.

Fractioning and/or preheating treatment on the rheological properties of myofibrillar protein (MP) gels induced by microbial transglutaminase (MTG) has been reported that they may improve the functional properties. However, the optimum condition was varied depending on the experimental factors. This study was to evaluate the effect of red bean protein isolate (RBPI) on the rheological properties of MP gels mediated by MTG as affected by modifications (fractioning: 7S-globulin of RBPI and/or preheat treatment (pre-heating; 95℃/30 min): pre-heating RBPI or pre-heating/7S-globulin). Cooking yields (CY, %) of MP gels was increased with RBPI (p<0.05), while 7S-globulin decreased the effect of RBPI (p<0.05); however, preheating treatments did not affect the CY (p>0.05). Gel strength of MP was decreased when RBPI or 7S-globulin added, while preheat treatments compensated for the negative effects of those in MP. This effect was entirely reversed by MTG treatment. Although the major band of RBPI disappeared, the preheated 7S globulin band was remained. In scanning electron microscopic (SEM) technique, the appearance of more cross-linked structures were observed when RBPI was prepared with preheating at 95℃ to improve the protein-protein interaction during gel setting of MP mixtures. Thus, the effects of RBPI and 7S-globulin as a substrate, and water and meat binder for MTG-mediated MP gels were confirmed to improve the rheological properties. However, preheat treatment of RBPI should be optimized.

다획성 어종인 고등어, 정어리, 말쥐치 등을 연제품 기타 식품소재로 이용하기 위해서는 다양처리를 위한 기계처리가 필요하나 적색육조에 많은 혈합육의 분리가 어려워 품질에 문제점이 있다. 기계처리적정에서 보통육과 혈합육을 분리하는 방법으로 당용액의 비중차에 의한 분리유과를 검토한 결과를 요약하면 다음과 같다. (1) 보통육과 혈합육을 분리할 수 있는 유효비중한계는 고등어의 경우 $1.067\sim1.072$, 정어리의 경우$1.02\sim1.070$ 말쥐치의 경우 $1.073\sim1.077$였다. (2) 육립자의 크기에 따른 분리율은 chopper 세공판의 공경이 0.2cm일 때에 $90\%$였고 0.3cm일 때에 $60\%$였다. (3) 육립자의 밀도에 따른 분리효과는 당용액에서의 침강력 높이가 1.8cm정도, 즉 육입자 밀도 $1g/cm^2$일 때 분리율이 $92\%$였고, 즉 $5g/cm^2$일 매에는 $59\%$로 낮았다. (4) 자당용액에서는 부상분리층이 25분 경과하여도 침강하지 않았으나 포도당액에서는 5분후부터 서서히 침강하였다. (5)당용액의 비중이 높아짐에 따라서 유지의 분리율 높았으며 유효비중한계내에서도 $90\%$정도의 지방을 분리할 수 있었다.

The Louisiana crawfish industry comprises the largest concentration of crustacean aquaculture in the United States. Processing plants throughout the culture region annually generate as much as 80 million pounds of peeling waste during recovery of the 15% (by weight) edible tail meat. A commercial oil extraction process for recovery of carotenoid astaxanthin from crawfish waste has been developed. Crawfish pigment in its various forms finds applications as a source of red intensifying agents for use in aquaculture and poultry industries. Crawfish shell, separated in the initial pigment extraction step, is an excellent source of chitin. Applicable physicochemical procedures for isolation of chitin from crawfish shell and its conversion to chitosan have been developed. Crawfish chitosan has been demonstrated to be both an effective coagulant and ligand-exchange column material , respectively, for recovery of valuable organic compounds from seafood processing wastewater.

Food allergy is one of the adverse food reactions, which is developed by immunological reactions. Food allergy is increasing in prevalence among children and adults. In the diagnosis, food challenge is confirmative with history and laboratory tests. Avoidance of culprit food is the only preventive method, especially in patients with severe symptoms. In some food allergies, cross-reactivity among allergens should be considered. Latex-fruit/vegetable syndrome and pollen food allergy syndrome are well-understood phenotypes of food allergy related to cross reaction. Red meat allergy is recently described as one of tick-borne diseases. In a rare phenotype of food-dependent exercise-induced anaphylaxis, factors affecting the absorption of food allergen are important in its pathophysiology.

The dramatic increase in colorectal cancer incidence in the population of East Asia indicates that diet and lifestyle play a role in colorectal cancer risk. Colorectal cancer prevention and etiologic studies have long provided dietary modification strategies for colorectal cancer prevention. In this review, we provide an overview of the epidemiologic evidence on the association between diet and colorectal cancer risk. Several cohort studies and a few intervention studies, most conducted in Western countries, have shown a possible link between red and processed meat, alcoholic beverages, calcium, vitamin D, vitamin B and the Western dietary pattern with colorectal cancer development. For colorectal cancer prevention in both Western and Asian populations, dietary modification is a key component of colorectal cancer prevention.
