Since organic rice storage silos were faced with an insect problem, an owner solved this problem using the expert system (ES) in the controlled atmosphere process (CAP) under the required standard, fumigating insects with an N2, reducing O2 concentration to less than 2% for 21 days. This article presents the computational fluid dynamics (CFD) assisted ES successfully solved this problem. First, CFD was employed to determine the gas flow pattern, O2 concentration, proper operating conditions, and a correction factor (K) of silos. As expected, CFD results were consistent with the experimental results and theory, assuring the CFD’s credibility. Significantly, CFD results revealed that the ES controlled N2 distribution throughout the silos and effectively reduced O2 concentration to meet the requirement. Next, the ES was developed based on the inference engine assisted by CFD results and the sweep-through purging principle, and it was implemented in the CAP. Last, the experiments evaluated CAP’s efficacy in controlling O2 concentration and insect extermination in the actual silos. The experimental results and owner’s feedback confirmed the excellent efficacy of ES implementation; therefore, the CAP is effective and practical. The novel aspect of this research is a CFD methodology to create the inference engine and the ES.

Spent coffee grounds (SCGs) are waste from coffee drink process, which are rich of a varieties of nutrients. This research applied SCGs as ingredient in cracker. The optimized formula and process are studied as well as addition of different levels of SCGs were studied. It was found that addition of SCGs in cracker had hedonic score in high level from panels, especially panels who drink coffee. Moreover, it was observed that SCGs could increase nutrients especially carbohydrate and fiber to the product.

This study focused on the development of an edible film containing Terminalia chebula Retz extract for the treatment of oral ulcers. The film was designed to dissolve in the mouth without the need for swallowing or chewing, which is suitable for people with canker sores or oral inflammation. Terminalia chebula extract has been shown to have several pharmacological properties, including antimicrobial, antioxidant, and anti-inflammatory activities.

This research gives a comprehensive overview of the use of antibiotics in livestock production, highlighting both the benefits and the risks associated with their use. The benefits, such as improving immunity, digestion, and reducing infections, are contrasted with the growing concern over antibiotic residues and the development of drug resistance. The shift towards alternatives like probiotics is explored as a sustainable solution, with a specific focus on lactic acid bacteria (LAB) found in the digestive systems of livestock. Thailand’s regulations, which control antibiotic use in animal feed, are also discussed, setting the stage for the study on LAB as a potential replacement for imported probiotics. 1. Use of Antibiotics in Livestock: Antibiotics have been used to promote growth, improve digestion, and prevent infections in livestock. However, the improper use of antibiotics can lead to residues in animal products and the development of drug-resistant bacteria. 2. Global Trends in Antibiotic Use: Many countries, like the European Union and Japan, have banned antibiotics as growth promoters, while others, like China and the U.S., are planning similar bans. 3. Thailand's Approach: Thailand has implemented a regulation since September 2020 to control the use of antibiotics in animal feed, requiring control at both feed mills and farms that mix their own feed. 4. Probiotics as an Alternative: Probiotics, particularly lactic acid bacteria (LAB), are being studied as an alternative to antibiotics. LAB are naturally found in the digestive tracts of livestock and are considered beneficial for maintaining gut health and replacing the need for antibiotics. The study examines the potential of LAB from Thai livestock (broilers, pigs, and cattle) as a sustainable alternative to imported probiotics, aiming to overcome issues like low survival rates of foreign probiotics in practice.
