In recent years, nanotechnology has been increasingly used in the food industry, especially to increase the food security. Nanotechnology provides the grounds to understand the food components on a small scale in the food industry. The present study aimed at analyzing the application of nanotechnology to improve the food security. The study sample included all experts (N= 90) of Iran's Nanotechnology Innovation Council selected by a census. This study used a descriptive-survey method. A questionnaire was developed based on the study’s theoretical framework and used for data collection. The validity (content and face) and reliability (factor loading, coefficient of composite reliability, and Cronbach’s Alpha coefficient) of the questionnaire were confirmed. The results of testing the hypotheses using Smart PLS, i.e., t-test and path coefficients (β), showed that the food packaging mechanisms directly and significantly affected food security improvement through using nanotechnology. The findings also displayed that the food preservation, processing, and production mechanisms influenced food security improvement through using nanotechnology. By using nanotechnology, the results indicated a direct relationship between foods' taste and color improvement as well as food safety and health improvement. [ABSTRACT FROM AUTHOR]

Green marketing has rapidly emerged as a global phenomenon around the world .As a result, some companies have responded to environmental challenges by applying green marketing strategies. However, with the increasing importance of environmental and health issues and the concept of social responsibility among consumers, recognizing behavior by actors and companies related to green products marketing is necessary. Therefore, this study helps to improve the understanding of green marketing behavior, which plays an important role in improving community health and economic growth. This study aims to design a green marketing behavioral pattern focusing on poultry products. The statistical population of this study is 145 actors who are involved in the production, distribution, promotion and pricing of green poultry products in Iran (Gilan Province). The findings indicate that attitudes toward green marketing (β: 0/94), subjective norms in relation to green marketing (β: 0/90) and feasibility (β: 0/67) had significant positive influences on intention toward green marketing. In addition, the results of green marketing behavior revealed that intention toward green marketing (β: 0/48), feasibility (β: 0.28) and government support (β = 0.56) were the three variables that influenced green marketing behavior, with government support having the greatest impact.
