This study examined the efficacy of natural ingredient formulated herbal medicine as feed additives against coccidiosis in broiler chicken. Medicinal herbs used in this study were Artemisia annua, Pulsatilla chinensis, Clematis chinensis and Scutellaria baicalensis. Two week old chicks were administered with 1% ingredient formulated herbal medicine. Observations of the efficacy were confirmed by examining the lesion score, histopathological appearance of cecum, shedding of fecal oocyst and production index in farm. S. baicalensis of the most effective substance were analyzed by UPLC. The results are as follows; among various types of Chinese medicine, the most efficacious ingredient was found to be pure bicalein. The major index substance is bicalein and $13{\mu}g/ml$ per gram was found. Feeding of chickens with S. baicalensis induced the coccidiostat effect and reduced the fecal shedding of E. tenella oocyst by 14%. Experimental results on a farm, feed conversion ratio and weight gain and production rate in the group with natural ingredient formulated additives than in control group increased. The rate of weight gain (%) in each experimental group showed 108% and 126% increase while the mortality rate was 1.4% lower than the control group. The investigation showed that the most efficacious ingredient was found to be S. baicalensis among herbal medicine products for coccidiostats. However, as it was found in the farm experiment that pure S. baicalensis alone is economically unviable. The additives with cocktailed of efficacious ingredient are suggested to be implemented for effective protection against coccidiosis.

Due to environmental pollution and human hazards of some synthetic dyes, the global fashion companies are increasingly interested in eco-friendly products, especially natural dye. For the globalization of natural dyeing industry based on this concern, however, there are some deficiencies of standardization, specification, and conformity assessment on natural dyestuffs as well as natural dyeing process. These obstacles should be not only studied but also defined for a commercial transaction. Accordingly, a study for conformity assessment on commercialized natural dyestuffs (red) was conducted by HPLC analysis in this study. As the results of HPLC analysis, alizarin and purpurin, representative index ingredients, were detected in most of the samples, but the index ingredient content in each sample was different. In addition, some samples showed the variety of peaks including the index ingredients and others. It was inferred that the representative index ingredients could be used on the traceability of natural sourced dyestuffs. These results are related to the index ingredient consistency, standardization, and reproducibility of natural dyed products including such as yarns, fabrics, garments, and so on. Therefore, the present study was demonstrated that in order to determine the conformity assessment system for the satisfaction of all stakeholders, the offering of information on the origin, manufacturing process, and index ingredient content of natural dyes should be prioritized.

The diet plays a fundamental role in the formation of the gut microbiota, determining the interrelationship between the gut microbiota and the host. The current study investigated the effect of Chlorella vulgaris on the gut microbiota by using simulated in vitro digestion and colonic fermentation. Bioaccessibility was measured after in vitro digestion, and SCFAs and microbial profiling were analyzed after colonic fermentation. The bioaccessibility of C. vulgaris was 0.24 g/g. The three major SCFAs (acetate, propionate, and butyrate) increased significantly when compared to the control group. In microbial profiling analysis, microorganisms such as Faecalibacterium, Dialister, Megasphaera, Dorea, Odoribacter, Roseburia, Bifidobacterium, Butyricmonas, and Veillonella were high in C. vulgaris group. Among them, Faecalibacterium, Dialister, Megasphaera, Roseburia, and Veillonella were thought to be closely associated with the increased level of SCFAs. Finally, it can be expected to help improve gut microbiota and health through ingestion of C. vulgaris. However, further studies are vital to confirm the changes in the gut microbiota in in vivo, when C. vulgaris is ingested.

For producing a high added-value natural seasoning ingredient, a yeast extract (Yx) was supplemented with a rice protein residue fermented with Bacillus licheniformis (Rfl) or with Bacillus subtilis (Rfs). A rice protein residue was obtained after enzymatic hydrolysis of rice protein which was used for preparing a yeast culture medium. Overall acceptabilities of the supplemented yeast extracts (YxRfl or YxRfs) were higher compared to pure yeast extract. Savory taste like umami was found to increase noticeably by adding a fermented rice protein residue to yeast extract, which was confirmed in taste sensor analysis and in sensory test. Beyond the presence of savory tasting amino acids such as Glu and Asp in a fermented rice protein residue, it is assumed that other soluble peptide fractions remained play an important role in enhancing taste of the supplemented yeast extracts. Thus, the yeast extract added with a fermented rice protein residue could be applied to manufacture a natural seasoning ingredient.

"Eating cosmetic" market comes to prominence worldwide. Inner Beauty has established itself as the top trend nowadays and is leading the health functional food market. Another noticeable trend other than beauty-from-within is that products using "plant-based" natural botanical raw material are increasing. Based on these trends above, we have developed a plant extract named Agatri® for skin health using Agastache rugosa. By ingesting Agatri®, it is expected that the formation of skin wrinkles is suppressed, and skin elasticity is increased by suppressing the decrease in collagen content caused by ultraviolet rays. At the same time, it is possible to prevent skin aging by improving skin hydration and trans-epidermal water loss (TEWL). The studies show that it significantly increased production of hyaluronic acid and collagen, and decreased production of matrix metalloproteinases (MMPs). And Agatri® has been approved as an "Individually recognized functional ingredient for skin health by the Ministry of Food and Drug Safety, Korea in 2020. As a result, Agatri® is a good solution for those who are in need of skin protection from exposure to UV and aging.

In this paper, we implement a recipe recommendation system using ingredient harmonization analysis based on recipe data. The proposed system receives an image of a food ingredient purchase receipt to recommend ingredients and recipes to the user. Moreover, it performs preprocessing of the receipt images and text extraction using the OCR algorithm. The proposed system can recommend recipes based on the combined data of ingredients. It collects recipe data to calculate the combination for each food ingredient and extracts the food ingredients of the collected recipe as training data. And then, it acquires vector data by learning with a natural language processing algorithm. Moreover, it can recommend recipes based on ingredients with high similarity. Also, the proposed system can recommend recipes using replaceable ingredients to improve the accuracy of the result through preprocessing and postprocessing. For our evaluation, we created a random input dataset to evaluate the proposed recipe recommendation system's performance and calculated the accuracy for each algorithm. As a result of performance evaluation, the accuracy of the Word2Vec algorithm was the highest.

Control of food pathogens is critical in food safety field. Norovirus is one of the major causes of gastroenteritis and food poisoning worldwide, however, currently, there is not a vaccine or a specific drug available for its treatment. There are several methods to inactivate norovirus during food processing by chemical and physical treatments, however, the use of natural substance has been suggested as an optional strategy due to their safety and consumer preference. In this study supported by Ministry of Food and Drug Safety in Korea, we identified novel plant-derived substances with significant anti-norovirus activities. The aim of this project was to determine the antiviral activity of a wide range of natural substances, including plant-derived extracts and essential oils, using a norovirus surrogate system, human norovirus replicon-bearing cells, and mouse in vivo experiments. During the activity screening test, we identified novel anti-norovirus substances or oils using plaque assay with MNV-1. Six selected substances were formulated into an optimum mixture and used as an ingredient for salad sauce of which anti-novovirus activity was confirmed(pending for patent and paper submission). The potential application of selected natural substances as a metal surface sanitizer was also tested. Interestingly, the mixture of selected natural compounds showed a significant inhibitory effect against norovirus. These results suggest that these substances may be used as food ingredient with anti-norovirus antivity or components for surface sanitizers to prevent norovirus contamination.
