Allergic rhinitis comes within snuffle in Chinese medicine. For generations, physicians have believed that the internal factors that cause this disease are pulmonary tuberculosis, splenic hypofunction and loss of virility, and its external factors are a cold, an uncommon atmosphere and an uncommon flavor. From the viewpoint of Chinese medicine, this symptom was fundamentally cured by "abidance by individuality, locality and seasons", on the basis of demonstration. In result, visceral function was recovered. In Chinese medicine, a disease is etiologically cured by the principles of Wholism and by discriminating among symptoms. In particular, "method for replenishing Qi and securing Exterior" has been widely used among the foregoing therapeutics. According to modern pharmacology, Astragli Radix, Atractylodis Macrocephalae Rhizoma and Ledebouriellae Radix all have antihistaminic effects and strengthen of the masticating and swallowing function of the recticuloendothelial system. This disease can be cured by controlling immunity and allergic reactions. Besides, it is necessary to take moderate exercise, to strengthen constitution, to avoid causative substances, to control ingesting flesh, meat and shrimps, to eat little, and to avoid what is cold and raw.

The brown soybean extract (BE, extracted by distilled water, 50%, 75%, and 95% ethanol) were analyzed for their total phenol, flavonoid, anthocyanin content, and DPPH radical-scavenging activity to determine antioxidant activities. Brown soybean extract with 75% ethanol showed significantly higher DPPH radical scavenging activity, total phenol and anthocyanin content compared to the other treatments (p<0.05). Then, brown soybean extract with 75% ethanol was applied to pork patties at different concentration (0.05%, 0.1%, and 0.2%) and lipid oxidation was evaluated during 15 d of refrigerated storage. Addition of BE significantly increased redness and pH values, respectively (p<0.05). Moreover, TBARS value of pork patties decreased significantly (p<0.05) as BE concentration increased. In sensory evaluation, pork patties with 0.1% BE had significantly higher score than other treatments in flavor and overall acceptability (p<0.05). Consequently, these results indicate that 0.1% BE could be an effective natural antioxidant to inhibit lipid oxidation in pork patties.

Dry-cured pork neck samples were stored at $10^{\circ}C$ for 90 days under vacuum packaging (VP) or modified atmosphere packaging (MAP; 25% $CO_2$+75% $N_2$) conditions. The pH, moisture, water activity, total aerobic bacteria, and Enterobacteriaceae counts of dry-cured pork neck products with MAP were significantly lower than those with VP (p<0.05) after 90 days of storage. However, CIE $b^*$ and 2-thiobarbituric acid reacted substance (TBARS) values of the pork product with MAP were significantly higher (p<0.05) than those with VP. Total aerobic bacterial counts and Enterobacteriaceae counts of samples with MAP were lower than those with VP after 30 days of storage. Sensory results indicated that aroma, flavor and tenderness scores of the samples with both VP and MAP decreased during storage and the scores after >60 days of storage were lower than those at Day 1. In conclusion, despite presenting higher lipid oxidation, the samples stored in packages containing 25% $CO_2$ for 90 days at $10^{\circ}C$ have lower bacterial counts than vacuum-packed samples. Therefore, further studies should be performed on the packaging of dry-cured meat at adjusted concentrations of $CO_2$.

The market size of home meal replacement (HMR) products has been gradually growing worldwide, even in Korea. In Korean HMR products, meat is the most important food ingredient compared with rice and vegetables. Therefore, this study aimed to evaluate changes in physiochemical and sensory aspects of beef under different preparation processes. For preparing four treatments, beef eye of round (ER) added with salt and sugar (treatment 1) and that without salt and sugar (treatment 2) were mixed with rice and frozen at $-50^{\circ}C$. Beef ER without salt and sugar was also topped onto the rice and frozen (treatment 3), and that was topped onto the rice and precooled before freezing (treatment 4). Physiochemical analyses included cooking and drip losses, shear force, color, salt soluble protein, and sensory attributes were tested. The results showed significantly higher drip loss and total loss in beef ER samples 1 and 2, which were mixed with rice, compared to beef ER samples 3 and 4, which were not mixed with rice. A significantly higher discoloration was also observed in beef ER samples 1 and 2, compared to that in samples 3 and 4. In the partial least squares regression (PLSR) analysis, beef ER sample 4 (precooled before freezing) was highly related to sensory attributes, such as flavor, overall acceptability, and juiciness, and far from non-preferred shear force. As a result, beef ER in HMR sample 4 was the most preferable to the sensory panel, and it had the most desirable physicochemical analysis outcomes.

This study was conducted to develop a topping formula for pizza containing Chungkukjang and onion as the main ingredients. The maximum amount of onion was limited to 10.5%, since the pizza crust and toppings would separate if too much water dispelled from the onion tissue during baking. The Chungkukjang was substituted for Bulgoggi, a meat topping. The sensory acceptability scores for the pizza topping decreased as the amount of Chungkukjang increased from 3.6% to 7.3%, due to its unpleasant odor, but scores increased when 1.6% Kimchi powder was added to the Chungkukjang without a significant difference from the control. Thus favorable sensory quality was obtained with a topping formula containing 8.7% Chungkukjang, 10.5% onion, and 1.6% Kimchi powder. The nutrient values of the final pizza products were assessed as follows. By adding the Chungkukjang and onion, crude protein, crude lipid, crude ash, and total dietary fiber contents increased. Moreover, the calorie level of the Chungkukjang-onion pizza was 3.8% higher than that of the control pizza. The amounts of compound amino acids including lysine increased. The free amino acids also increased from 143.3 to 188.6 mg/100 g. The ratio of saturated fatty acids to unsaturated fatty acids changed from 1:0.71 to 1:0.81. For the consumer test, the age groups of the participants were classified as 15-29 years old, 30-39 years old, and 40-62 years old. A positive result on acceptability of the developed pizza was obtained from most of the panelists in all age groups. Over 93% of the 119 responding subjects had purchasing intentions. An, especially, strong purchaging intention was shown in the younger age group of 15-29 year-olds, even though they had a lower preference for the Chungkukjang. Finally, an attribute of satisfaction was induced based on 'health' (79.5%) and 'flavor' (15.7%).

There is a need for newer feed additives due to legal prohibition on inclusion of growth promoting antibiotics in livestock diets in several countries due to antimicrobial resistance. In this context, rare earth elements (REE) have gained attention among animal nutritionists as potential growth promoters. Currently, several studies have reported better weight gain, milk production, egg laying capacity and feed conversion efficiency among different breeds of farm animals following supplementation with REE, with however largely inconsistent results. Furthermore, REE supplementation has also shown to improve ruminal fibrolytic and proteolytic activities as well as flavor of meat with negligible residues in edible tissue, however the mechanism behind this action is still unclear. According to existing research, due to their poor absorption and similarity with calcium REE might exert their action locally on gut microbial populations within the gastrointestinal tract (GIT). Moreover, REE have also shown anti-inflammatory, anti-oxidative as well as immune stimulating effects. The present review aims to broaden the knowledge about use of REE as feed additives for livestock and sum up efficacy of REE supplementation on performance and health of animals by comparing the findings. Till date, researches with REE have shown properties that make them a promising, new and safe alternative feed additive but further exploration is recommended to optimize effects and clarify discrepancy of various results before practical proposals can be drafted.

This was conducted to investigate the dietary assessment, food preferences, snack intake, priority order in food purchase, and knowledge of diet of full-time housewives and working housewives through the use of a questionnaire. The participants (127 working housewives and 86 housewives) were selected at random from Seoul and its vicinity. The predominant job reported by working housewives was saleswomen and specialized job (20.7%). The average monthly income of both housewives and working housewives ranged from 3,000,000 to 5,000,000 won. Forty percent of housewives consumed more meat, fish, eggs, beans, and tofu, while 50.0% of housewives ate vegetables other than kimchi at every meal, 51.2% of housewives consumed one serving of fruit and one cup of fruit juice, 45.3% of housewives consumed three regular meals, and 60.5% of housewives consumed a balanced diet when compared with working housewives (p<0.05). Working housewives consumed beverages, ice cream, milk, and dairy products, while housewives consumed breads, sweet potato, potato, and fruit as snacks. The preference that most often led to food selection was flavor among working housewives (67.7%) and housewives (64.0%). Both working housewives and housewives always confirmed the day of food production. Generally, housewives were more interested in learning about food, creating a dietary plan, nutrient loss during cooking and reducing waste food when compared with working housewives. Housewives appeared to have better dietary assessment and knowledge than working housewives. Accordingly, it is advisable to prepare more systemic education programs for working housewives.

The effects of feeding of diets based on roughage supplemented with concentrate on the carcass and meat quality attributes of Korean black goats were investigated. The 40 male goats at 5 mon age were divided into four treatment groups; T1 (1.5%), T2 (2.0%), T3 (2.5%) and T4 (ad libitum) feeding of concentrate with ad libitum rice straw. Forty bucks at the end of the feeding were fasted for 12 h before slaughter and were then slaughtered. For carcass measurement, cold buck carcasses were examined after 24 h of chilling at $5^{\circ}C$. The carcasses were chilled in refrigerator at $2{\pm}2^{\circ}C$ for 24 h, then the longissimus dorsi muscle was removed from the carcasses. The samples were separately vacuum packaged, frozen and stored at $-20^{\circ}C$ for up to 1 mon, prior to physicochemical evaluations. Carcass yields were greatly affected by rate of concentrate feeding. T4 showed the heaviest live and carcass weights and the highest dressing and fat percentages (p<0.05). The moisture contents were lower in T4 compared with other treatments, while the crude protein and fat contents were higher (p<0.05). mono-unsaturated fatty acid in T4 was significantly higher than others, which showed the highest percentages of oleic acid (C18:1). For the sensory test, T4 was tenderer and produced better flavor scores than others. Increasing the level of concentrate in the diet resulted in an improvement in growth performance, and carcass and physicochemical characteristics of goat meats.

This study investigated the antioxidative and functional effects of a curing agent containing grapefruit seed extract (GSE) on the quality and storage characteristics of chicken breast. The total polyphenol and total flavonoid contents of GSE were 45.06 mg/g and 36.06 mg/g, respectively. The $IC_{50}$ value of 2,2-diphenyl-1-picrylhydrazyl hydroxyl scavenging of GSE was $333.33{\mu}g/mL$. The chicken breast comprised six groups: no-treatment (N), 0.2% ascorbic acid + 70 ppm sodium nitrite (C), 0.05% GSE (G0.05), 0.1% GSE (G0.1), 0.3% GSE (G0.3), and 0.5% GSE (G0.5). The pH and cooking loss of cured chicken breast decreased with increasing GSE levels, and the water holding capacity increased with increasing GSE levels. The hardness and chewiness of GSE-treated chicken breast were higher than those of N and C. Hunter's L and a color values increased significantly after GSE addition. Moreover, 0.1% GSE (G0.1) increased the flavor and total acceptability scores. The 2-thiobarbituric acid and volatile basic nitrogen values of the 0.5% GSE group decreased significantly compared with those of C group. Total microbial counts of GSE-treated chicken breast were higher than those of C, but that lower than those of N. Adding GSE to chicken breast delayed lipid peroxidation and had antimicrobial effects during cold storage. GSE improved shelf life and palatability; therefore, it could be used as a natural antioxidant and functional curing agent ingredient in meat products.
