Spent coffee grounds (SCG) are a byproduct of the coffee brewing process, and their quantity continues to increase due to the growing global coffee consumption. SCG contain beneficial compounds such as polysaccharides, dietary fibers, and antioxidants, which can be utilized in various applications, including prebiotic extraction. This study focuses on extracting prebiotics from SCG using acid hydrolysis and enzymatic hydrolysis methods to evaluate their potential in promoting the growth of beneficial gut microorganisms. The expected results of this research include adding value to coffee industry waste, reducing organic waste, and providing a sustainable approach to developing prebiotic products for use in the food and health industries. Furthermore, this study aligns with sustainable resource utilization and environmentally friendly practices.

Dwarf whipray (Brevitrygon heterura) is a common species found in a local market in the Gulf of Thailand. However, like many other species of stingrays, it is threatened by overfishing and habitat destruction. Therefore, an accurate species identification is crucial because conservation efforts may vary depending on the species. This study aims to understand morphological variation of B. heterura in the Gulf of Thailand by morphometric study and genetic analysis. During October 2022 and February 2023, we obtained 49 samples from research vessels fish landing ports and local fish markets. We observed two distinct groups based on 43 morphological variables/ratios. B. heterura samples from Chanthaburi, Rayong, Chonburi, Samut Sakhon, Nakhon Si Thammarat and Songkla provinces, called “group A," typically have longer snout length than those from Prachuap Khiri Khan provinces, called “group B" according to external morphological characters for species identification. Three morphological variables/ratios were significantly different between groups A and B. Main characters to explain intraspecific variations between group A and group B are further discussed. DNA barcoding based on a fragment of the cytochrome c oxidase subunit I (COI) gene were obtain from eight samples of group A and eight samples from group B. Pairwise percent sequence divergence (p-distance) for COI between group A and group B were 0.0-2.5. This study contributes to the understanding of variations of morphology and genetics of B. heterura in the Gulf of Thailand.

This study was conducted to develop a prototype cooling cover for transporting raw milk, aiming to provide a solution for maintaining the quality of raw milk during transportation to milk collection centers. The cooling cover is made using Phase Change Material (PCM), produced from water mixed with a gelling agent, in an amount of 5.6 kg, attached around an aluminum milk tank (with a capacity of 25 L). The cover is then covered with a UV-reflective fabric in two types: polyvinyl chloride (PVC) and high-density polyethylene (HDPE). The temperature reduction performance of both types of covers was evaluated by measuring water temperatures at various points along the radial and vertical directions of the milk tank at six points, using type-T thermocouples, under three environmental conditions: a constant temperature of 25 °C, 35 °C, and outdoor ambient temperature (average temperature 35.5 °C) for a minimum duration of 180 min. The experimental results revealed that at 120 min., the water in the tank covered with PCM-PVC and PCM-HDPE covers had temperatures lower than the ambient temperature by 12.6 °C and 12.9 °C, respectively, under a constant ambient temperature of 25 °C, and under a constant ambient temperature of 35 °C lower by 16.7 °C and 16.4 °C, respectively, and outdoor conditions. Since the temperature reduction performance of PCM-PVC and PCM-HDPE covers showed no significant difference, the performance of microbial quality preservation of raw milk was assessed only with PCM-PVC cover in comparison to a non-covered case (control), by measuring coliform and Escherichia coli counts using compact dry plates. Results indicated that after 120 min., milk in the tank covered with PCM-PVC had an average coliform count of 1.6 × 10^4 CFU/ml and E. coli count of 2 × 10^3 CFU/ml, which was lower than the non-covered control with an average coliform count of 1.5 × 10^4 CFU/ml and E. coli count of 1.1 × 10^4 CFU/ml. This study concludes that the temperature reduction achieved by the cooling cover can help inhibit coliform growth to levels below raw milk quality standards, demonstrating the potential of the cooling cover in maintaining the quality and safety of raw milk during transport, ultimately contributing to an improved quality of life for Thai dairy farmers.
