Coconut residue (CR) is a major by-product generated during the wet processing of virgin coconut oil (VCO). Despite its potential as a raw material for value-added products such as dietary fiber, it remains underutilized due to its perishable nature, highlighting the need for appropriate pretreatment to improve safety and quality prior to valorization. This study evaluated the effects of thermal pretreatments, namely pan-roasting at 65–70 °C, hot-air drying at 50 °C and 60 °C, and their combinations, on the microbiological and physicochemical properties of CR. Microbiological quality was assessed through aerobic plate count, yeast and mold count, and total coliform analysis, while physicochemical properties were evaluated using pH, titratable acidity (TA), and instrumental color measurements. Results showed that CR subjected to pan-roasting, either alone or followed by drying at 60 °C, maintained acceptable microbial counts and generally exhibited lower TA and higher pH compared to other treatments, suggesting improved stability and reduced acidity development. However, pan-roasting caused color changes as reflected by a significant reduction in lightness (L*) values relative to the control. Overall, pan-roasting could serve as a promising thermal pretreatment step to enhance microbiological safety and preserve the physicochemical quality of CR. While these results indicate its potential for preparing CR for dietary fiber valorization, confirmation through analysis of fiber content, techno-functional properties, and validation using CR from commercial VCO processing facilities is still required.

Inga edulis Mart. (Fabaceae) is a multipurpose fruit tree widely cultivated in Ecuador. We explored how contrasting cultivation systems are associated with variation in fruit traits and genetic diversity by comparing agroforestry plantations and traditional home gardens. Trees in agroforestry systems exhibited significantly larger pods whereas home-garden populations showed higher levels of genetic diversity. These patterns suggest a potential trade-off between productivity-oriented management and the maintenance of genetic variation, possibly reflecting differences in management practices and seed sourcing. These results highlight the complementary roles of agroforestry and home gardens in the sustainable use and in situ conservation of I. edulis within traditional landscapes.

This collection presents the accepted abstracts for the 3rd International Online Conference on Agriculture (IOCAG2025), organized by the MDPI journal Agriculture, and held online from 22 to 24 October 2025. The event highlighted integrative solutions and data-driven innovations for building resilient agricultural systems, spanning topics from climate-smart practices, precision water management, and AI-enhanced smart farming to sustainable crop protection, soil health, and advanced crop genetics. Discussions emphasized translating research into practical applications that balance productivity with environmental stewardship. Collectively, IOCAG2025 showcased forward-looking approaches and collaborative insights aimed at advancing sustainable, efficient, and climate-adapted agriculture on a global scale.
