Plant-based refers to food or products that are primarily made from plants. It can be divided into two categories: one is food that comes entirely from plants and does not include any animal products, and the other is food that contains small amounts of animal products, such as products that contain milk and eggs in limited quantities, which may also be considered part of the definition of plant-based. Plant-based meat products that closely resemble real meat and attract consumers are considered a relatively new innovation. Although tofu, tempeh, and seitan have been around for a long time, recent discoveries have led to the production of plant-based meat products that provide a sensory experience, making it difficult for consumers to distinguish between real meat and plant-based meat. Furthermore, the development of plant-based food products must prioritize quality and safety to maximize consumer benefits. Textured Vegetable Protein (TVP) is a plant-based protein made from soybeans using an extruder. It is used as a primary ingredient in the production of plant-based food products due to several advantages. These include: • High Protein Content: TVP is made from soybeans with the fat extracted, resulting in a high protein content. • Texture: When rehydrated, TVP has a texture that closely resembles meat. • Versatility: TVP has a neutral flavor, allowing it to easily absorb the flavors of various seasonings and sauces. • Cost-Effectiveness: Compared to other protein sources, TVP is relatively inexpensive while providing desirable characteristics. These benefits make TVP an attractive option in the production of plant-based foods. This study focuses on developing TVP into a plant-based crab cake and investigating the shelf life of the product in a tightly sealed container under refrigeration. It also analyzes the hygiene and cleanliness of the production process and how these factors affect the presence or growth of microorganisms that may pose a risk to consumers, referencing the cold food safety standards of Thailand. Finally, recommendations for cleaning operational areas will be provided to establishments as a guideline for developing preliminary food safety procedures in laboratory settings.

This research focuses on the design and development of a high-power converter to regulate energy supply from solar cells (Photovoltaic: PV) to a hydrogen production unit (Electrolyzer), which is a crucial component in advancing renewable energy in alignment with the RE100 initiative. Specifically, this study targets Green Hydrogen, which is generated through the water electrolysis process using clean energy from solar cells, ensuring zero emissions and environmental sustainability. The proposed converter includes of a Three-Level NPC Inverter, transformer, Full-Bridge Rectifier, and LC filter to enhance the power quality supplied to the electrolyzer. The system's design and simulation were conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Simulation was conducted using MATLAB and Simulink to evaluate circuit performance and analyze operational efficiency. Additionally, a microcontroller-based control system is integrated with a gate driver circuit to optimize the electrolysis process by reducing power losses. This proposed converter effectively converts PV energy into suitable voltage and current levels for the electrolyzer while maintaining high hydrogen production efficiency.

The concept of building a friendly city for older people by adjusting the physical environment is considered one of the crucial components of promoting older people’s better health and quality of life. Based on this tenet, designing a suitable footpath and considering older people’s needs are vital to the reduction of risks and the increase of safety in travelling, especially for older people living in Wat-Thad and Wat-Klang communities where the proportion of the elderly has continuously, increased. The research aimed to 1) survey the physical environment of footpath, approaching public assistance, 2) observe the elderly’s behavior and satisfaction on footpath in communities, and 3) create the proposal concept in developing the suitable footpath with the elderly’s need in city area. This research used various tools, including the questionnaire on the footpath’s physical environment to analyse problems, limitations, and footpath potentials, the interview of staff in the Engineering Division, Khon Kaen municipality and the questionnaires collecting travelling behaviour, satisfaction and attitude of elderly on the footpath in community. The data analysis the physical environment following six components in the monitoring list showed three used descriptive statistics. Interestingly, from 370 samples, the results of investigating qualified evaluations, namely 1) land utilisation in the communities, 2) linking the transportation network, and 3) beautifully attractive places for walking. However, three unqualified evaluations were 1) safety footpath availability, 2) design for all people, and 3) walking on the footpath to access public assistance and facilities. Moreover, the results from the questionnaire to study older people’s travelling behaviour, indicated that the most travelling objectives were grocery shopping and accessing the recreation sites with frequent visits three to five times per week. Furthermore, older people’s satisfaction with the community footpath was overall at a high level, This research proposed suggestions for developing a safe footpath to ensure safe walking access to facilities and public assistance.
