This study aims to investigate the co-encapsulation technique of vitamin C and coenzyme Q10 within liposomes to enhance their stability and encapsulation efficiency and evaluate their antioxidant activity and release behavior under simulated gastrointestinal conditions. Liposomes were prepared using the High-Speed Homogenization Method, and their characteristics, including particle size, zeta potential, encapsulation efficiency, and antioxidant activity, were analyzed using DPPH, ABTS, and FRAP assays. The results demonstrated that co-encapsulation significantly improved the stability of vitamin C and coenzyme Q10 compared to single encapsulation. The liposomes exhibited high encapsulation efficiency and maintained strong antioxidant activity. The release profile under simulated gastrointestinal conditions also indicated a sustained and controlled release. These findings highlight the potential of the co-encapsulation technique in enhancing the efficacy of functional bioactive compounds, making it applicable to the food and nutraceutical industries.

This research suggested natural hemp fiber-reinforced ropes (FRR) polymer usage to reinforce recycled aggregate square concrete columns that contain fired-clay solid brick aggregates in order to reduce the high costs associated with synthetic fiber-reinforced polymers (FRPs). A total of 24 square columns of concrete were fabricated to conduct this study. The samples were tested under a monotonic axial compression load. The variables of interest were the strength of unconfined concrete and the number of FRRlayers. According to the results, the strengthened specimens demonstrated an increased compressive strength and ductility. Notably, the specimens with the smallest unconfined strength demonstrated the largest improvement in compressive strength and ductility. Particularly, the compressive strength and strain were enhanced by up to 181% and 564%, respectively. In order to predict the ultimate confined compressive stress and strain, this study investigated a number of analytical stress–strain models. A comparison of experimental and theoretical findings deduced that only a limited number of strength models resulted in close predictions, whereas an even larger scatter was observed for strain prediction. Machine learning was employed by using neural networks to predict the compressive strength. A dataset comprising 142 specimens strengthened with hemp FRP was extracted from the literature. The neural network was trained on the extracted dataset, and its performance was evaluated for the experimental results of this study, which demonstrated a close agreement.

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.

The production process of the food rancidity indicator label consists of three main steps: 1) preparation of the indicator solution, 2) preparation of the cellulose solution, and 3) formation of the sheet. The indicator solution includes bromothymol blue and methyl red, which act as indicators. The cellulose solution consists of hydroxypropyl methylcellulose, carboxymethyl cellulose, sodium hydroxide, polyethylene glycol 400, and the indicator solution. For the sheet formation, the cellulose solution was mixed with natural latex to increase flexibility and impart hydrophobic properties. After drying, the invention appears as a thin, dark blue label. When exposed to volatile compounds from rancid food, the label changes color from dark blue to green, and then to yellow, corresponding to the increasing amount of volatile compounds from the rancid food.
