Continuing education (CE) plays a crucial role in workforce development and economic growth across Asia, yet the landscape of CE research in the region has not been comprehensively mapped. A comprehensive bibliometric analysis of continuing education (CE) research in Asia from 1972 to 2023 was carried out, utilizing data from the Scopus database to map the evolving landscape of CE research in the region. Findings revealed a significant surge in research output since the late 1990s, with East Asian countries, particularly China, Hong Kong (China), and Taiwan (ROC), emerging as leaders in the field. The analysis uncovers several key patterns: institutional collaborations tend to cluster regionally, there's a noticeable generational gap in researcher's networks, and the healthcare sector dominates CE research topics. Recent trends indicate a shift towards digital learning approaches and learner-centered methodologies. The study also highlights the need for increased cross-border collaborations and expansion of CE research beyond the healthcare sector. This research contributes to a deeper understanding of CE research trends in Asia and provides insights for future directions in the field.

Purpose: This study aims to investigate the effect of spray drying temperature and maltodextrin addition on the contents of phenolics, flavonoids, anthocyanins and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl [DPPH] radical scavenging activity, ferric reducing antioxidant power and reducing power) of karonda powder. Design/methodology/approach: Over the past few decades, the demands for application of natural colorants in food production have been attracting the attention of academic research and food industry. Anthocyanins, a red pigment commonly found on plants, show high potentials in the preparation of spray-dried pigment powder. This study, therefore, was conducted using full factorial design with two factors, namely, inlet temperature (150°C and 160°C) and soluble solid concentration (10, 15 and 20°Brix) with maltodextrin as carrier to produce pigment powder from karonda, an anthocyanin-rich fruit which is native to southeast Asia. Findings: Increasing soluble solid content from 10 to 15°Brix resulted in a 42%–57% reduction in phenolic, flavonoid and anthocyanin contents. However, when increasing the amount of maltodextrin from 15 to 20°Brix, a lower reduction (approximately 11%–19%) was observed. In samples with the same °Brix, there was no significant variation in antioxidant contents and activities, especially at high maltodextrin ratios. In addition, the reducing power of samples dried at higher temperature (160°C) was higher than that of samples dried at lower temperature. Karonda spray-dried powder showed a good positive correlation (p < 0.01) between antioxidant contents and DPPH• activity. Originality/value: To the best of the authors' knowledge, in this study, for the first time, the effect of spray drying conditions on the quality of karonda powder was investigated.
