Consumers' growing interest in the environment has recently led them to recognize the importance of their dietary life and sustainable consumption. Thus, there is an increasing necessity to identify consumers' response on the relationship between the consumption of functional food and their interest in helping environment. This research was conducted to analyze consumers' behaviors as related to Spirulina, an eco-friendly functional food brand, by subdividing markets according to consumers' food lifestyle. The results showed that consumers were categorized into 3 types (high involvement in diet, pursuit of safety in diet, and pursuit of convenience in diet), and there was a significant difference in the consumption behaviors of the functional food according to the 3 types. Their positive attitude towards functional food and interest in the environment led to changes of their actual purchasing behavior by increased purchase of Spirulina. Also, consumers who displayed high environmental involvement showed a more favorable attitude towards functional food. Therefore, to expand the market of eco-friendly functional food, it is necessary to subdivide the market and target the consumers who are highly involved with protecting the environment, and to execute marketing strategies for eco-friendly products, in order to increase the consumers' awareness about eco-friendly functional food.

The goal of this study is to promote the spread of environmentally friendly agricultural products, which have been receiving a lot of attention lately, as a way to improve food safety and quality. As a result of the increased labor input, increased production costs, and an aging population, environmentally friendly agriculture is making it more difficult for farmers to expand their enterprises. In the meantime, consumers find it difficult to spread eco-friendly agricultural products due to their high expectations for safety and quality, as well as the desire to purchase products at a reasonable price. Previous studies have revealed differences in perceptions between eco-friendly agricultural producers and consumers. In light of this, this study divided consumers based on their characteristics (such as age, purchase history, health concerns, etc.), and different policies were proposed in order to increase purchasing factors for each group based on their characteristics. In order to gather information for this study, general citizens were asked about their perceptions of eco-friendly agricultural products, future purchase intentions and awareness, reliability, necessity, purpose, and information sources. A two-step clustering analysis was conducted using nominal and continuous variables simultaneously. The paper presents the three derived group differences (senior organic interest group, middle-aged organic interest group, and indifferent young organics) as well as group differences for the purchasing/non-purchasing factor analysis and policy improvement for each group. An eco-friendly agricultural product distribution proposal was made at the end of this article.

This study analyzed consumer needs for the development of elderly-friendly HMR products in China. In developing the products, items needed to be improved, types and packages of the necessary products, additional improvements and food preferences were investigated. According to the demographic characteristics of elderly Chinese consumers, these was analyzed as well. A survey was conducted on a total of 370 elderly people, and data analysis was performed using SPSS 18.0 program. Items related to product quality safety, such as "marks of origin by ingredient", "rich nutrients", "expansion of letter size of packaging", "rich nutrients" and "clear manufacturing date and expiration date", were required to develop HMR products. The types of products that should be developed were porridge and noodles, and the packaging types that should be developed were eco-friendly packaging and recycled packaging. In addition, "low-calorie HMR", "development of various seasonings", "use of eco-friendly food ingredients" and "HMR to digest easily" should be improved. The demand for product improvement and food preference showed significant differences according to the degree of education, monthly income and oral health. The results were intended to prepare basic data for setting the direction when developing elderly-friendly HMR.

The purposes of this study were to identify awareness of pollution and attitudes toward eco-friendly clothing according to women's LOHAS lifestyle. Over 60% of women were not aware of severity of environment pollution by clothing wastes and 37.2% kept their not-wearing clothing in dead storage. 26.7% of women disposed not-wearing clothing into clothing collecting box separately and 20.9% sent them to neighbors or friends. 39.4% of women were willing to pay 10% more for eco-friendly clothing and 84.6% were not willing to buy clothing produced by unethical companies. Factors of LOHAS lifestyle were healthy food, environmental protection, family life, healthy clothing, healthy housing, and community service, and were segmented into using leisure group, family centered group, LOHAS group, and LOHAS stagnated group. Using leisure group were university women with low incomes, well aware of environmental pollution by clothing wastes and eco-friendly clothing, kept their not-wearing clothing into dead storage, and low intention to buy clothing produced by unethical companies. Family centered group were women of 30’s with average income and higher educationl, unaware of environmental pollution by clothing wastes and eco-friendly clothing, but low intention to buying them, disposed not-wearing clothing into clothing collecting box. LOHAS group were the over forties home makers with higher income and education, well aware of severity of environmental pollution, sent not-wearing clothing to others or remodeled, intended to buy eco-friendly clothing, and not to buy clothing produced by unethical companies. LOHAS stagnated group were university students, unaware of severity of environmental pollution by clothing wastes and threw not-wearing clothing into trash box, no experience of eco-friendly clothing, could buy clothing produced by unethical companies if needed.

We previously reported that the SbROMT3syn recombinant protein catalyzes the production of the methylated resveratrol derivatives pinostilbene and pterostilbene by methylating substrate resveratrol in recombinant E. coli. To further study the production of stilbene compounds in E. coli by the expression of enzymes involved in stilbene biosynthesis, we isolated three stilbene synthase (STS) genes from rhubarb, peanut, and grape as well as two resveratrol O-methyltransferase (ROMT) genes from grape and sorghum. The ability of RpSTS to produce resveratrol in recombinant E. coli was compared with other AhSTS and VrSTS genes. Out of three STS, only AhSTS was able to produce resveratrol from p-coumaric acid. Thus, to improve the solubility of RpSTS, VrROMT, and SbROMT3 in E. coli, we synthesized the RpSTS, VrROMT and SbROMT3 genes following codon-optimization and expressed one or both genes together with the cinnamate/4-coumarate:coenzyme A ligase (CCL) gene from Streptomyces coelicolor. Our HPLC and LC-MS analyses showed that recombinant E. coli expressing both ScCCL and RpSTSsyn led to the production of resveratrol when p-coumaric acid was used as the precursor. In addition, incorporation of SbROMT3syn in recombinant E. coli cells produced resveratrol and its mono-methylated derivative, pinostilbene, as the major products from p-coumaric acid. However, very small amounts of pterostilbene were only detectable in the recombinant E. coli cells expressing the ScCCL, RpSTSsyn and SbROMT3syn genes. These results suggest that RpSTSsyn exhibits an enhanced enzyme activity to produce resveratrol and SbROMT3syn catalyzes the methylation of resveratrol to produce pinostilbene in E. coli cells.

This study examines how eco-innovation contributes to the exports of environmentally-friendly products using the dynamic panel model. The results reveal that the adjustment in the exports exists to recover the long-run equilibrium with sluggish adjustment speed. In addition, the results show that environmental patent applications and environment-related R&D expenditures are beneficial for enhancing the environmentally-friendly exports. While the environmental patent applications are associated only with an increase in the exports of products for resource management, the environmental R&D expenditures contribute to the exports of pollution management products, cleaner technologies and products, and resource management products. Moreover, as the long-run effects of eco-innovation on the exports become greater than the short-run effects, it appears that public eco-innovation is more likely to support future exports than private eco-innovation.
