Vanillyl alcohol (VA), which is abundant in Vanilla bean, has strong antioxidant activity. However, the use of VA in the food and cosmetics industries is limited, due to its low solubility in emulsion or organic solvents. Meanwhile, medium chain fatty acids and medium chain monoglycerides have antibacterial activity. We synthesized butyric acid vanillyl ester (BAVE) or caprylic acid vanillyl ester (CAVE) from VA with tributyrin or tricaprylin through transesterification reaction using immobilized lipases. BAVE and CAVE scavenged 2,2-diphenyl-1-picrylhydrazyl radicals in organic solvents. In addition, BAVE and CAVE decreased the production rate of conjugated diene and triene in the menhaden oil-in-water emulsion system. While BAVE showed no antibacterial activity, CAVE showed antibacterial activity against food spoilage bacteria, including Bacillus coagulans. In this study, the antibacterial activity of vanillyl ester with medium chain fatty acid was first revealed. Zeta potential measurements confirmed that BAVE and CAVE were inserted into B. coagulans membrane. In addition, the propidium iodide uptake assay and fluorescent microscopy showed that CAVE increased B. coagulans membrane permeability. Therefore, CAVE is expected to play an important role in the food and cosmetics industries as a bi-functional material with both antioxidant and antibacterial activities.

The aim of this study is to examine the patterns of expressing contemporary beauty from the perspective of Laotzu's philosophy in order to suggest its concept and characteristics and to suggest specific cases through cosmetics advertisement. In doing so, the study attempted to understand that contemporary beauty is more humanistic and liberal in terms of expression patterns than in any other time period. The research results are as below. The frame concept of Laotzu's philosophy includes 1. Naturalness, 2. coexistence in Conflict, and 3. Non-otherness. The characteristics of contemporary beauty are natural and healthy, People can foresee changing beauty by the cycle of life and, by admitting this philosophy, people can understand one's individuality and discover self-esteemed beauty. Also, the results from the cases of cosmetics advertisement are as below: 1. Naturalness was remarkable. Such phenomenon was common in representative brands of the research subjects. Expression pattern was based on soft, natural make-up and hair style. 2. For conflict and coexistence, they introduced the ancient image of the situation, and the situational image using food and herbs demonstrated a functional, situational image, which was used for the cosmetics advertisement based on the mutual coexistence concept instead of dichotomy of period or material. 3. Non-otherness advertisement, of which there was none, we expected that maximized marketing effect would be achieved if non-otherness cosmetics advertisement expressed the contemporary beauty because it could solicit sympathy form many consumers.

In this study, we tested the anti-inflammatory effects of broccoli leaf hexane fraction to confirm the applicability as a functional material in food and cosmetics. This sample was extracted using 70% ethanol from Broccoli leaf and then fractionated with hexane. The production of pro-inflammatory cytokines (TNF-α, IL-4, IL-6, IL-1β), protein expression of iNOS and COX-2, phosphorylation of MAPKs (ERK, JNK, p38) and NF-κB with broccoli leaf hexane fraction were assayed on LPS-stimulated RAW264.7 cells. The broccoli leaf hexane fraction inhibited the secretion of pro-inflammatory cytokines and protein expression of iNOS and COX-2. Also, the broccoli leaf hexane fraction reduced the phosphorylation of MAPKs and NF-κB. Therefore, it is considered that th broccoli leaf hexane fraction has the potential to be used as a natural anti-inflammatory material in food and cosmetics. In the future, it is considered necessary to study the anti-inflammatory mechanism and identification of major bioactive substances.

This study was to investigate the chemical properties and nitrite scavenging and acetylcholinesterase inhibitory activities from Salicornia herbaciea seed. The lactic acid content of seed was about 2.0 fold higher than that of stem. Among various free sugars, the maximum fructose of seed, glucose of stem, and mannose contents of root were obtained, 176.3, 125.6, and 112.8 mg/100g, respectively. The maximum leucine content of seed among the essential amino acid was obtained, 853.7 mg/100g, which was about 3.0 or 6.0 folds higher than that of root or stem. In the case of glutamic acid of seed, it was 2,388.7 mg/100g, which was 5.6 or 9.8 folds higher han that of root or stem. The ratio of essential amino acid and total amino acid of seed was 30.14%. The ${\gamma}$-aminobutyric acid contents of seed, stem, and root were 43.87, 23.88, and 27.8 mg/100g, respectively. The catechin content of seed was an order of epigallocatechin (723.2 mg/100g) > epigallocatechingallate (654.3 mg/100g) > epicatechin (443.5 mg/100g) > gallocatechin (314.1 mg/100g). Especially, the non-gallated catechins content was about 2.0 folds higher than that of gallated catechins content. The nitrite scavenging activity of seed increased from 38.7 to 65.9% when the hot-water extract content of seed at pH 1.2 increased from 1.0 to 5.0 mg/mL. However, it was decreased to 25.7% at pH 6. The acetylcholinesterase inhibitory activity of seed was increased from 13.2 to 44.6% when the extract content increased from 20 to 100 mg/mL. These results show that S. herbaciea seed has a good potential to be used as a source of material or additive in cosmetics, food, and drug compositions.

In today's society, functional whitening cosmetics are important to beauty. Fungi are known to produce a variety of whitening-related metabolites. In this study, we searched for tyrosinase inhibitors with metabolic products derived from Trichoderma atroviride supernatant in order to apply a material for whitening functional cosmetics. In addition, the inhibitory effect was compared to arbutin, which has already been approved as a whitening raw material by the Korea Ministry of Food and Drug Safety (KMFDS). The metabolites from the T. atroviride supernatant showed higher tyrosinase inhibitory activity than that of arbutin. Some of the tyrosinase inhibitors were stable to heat, whereas some were unstable. The heat unstable material was exhibited in the case of samples treated with little amounts, such as 0.02~0.2%. They were very unstable in acidic and alkali pHs, especially under acidic conditions. However, it was found that a weakly-acidic to neutral pH range was the optimal working pH, especially neutral pH. Since the activity of the inhibitory substances in the T. atroviride supernatant was maintained regardless of proteinase K treatment, it was assumed that the metabolites, but not the bioactive peptides, were involved in the activity. In summary, we propose that the metabolites derived from T. atroviride supernatant have strong potential as whitening raw material.
