“…While coconut-based alternatives offer promising sustainability advantages, certain challenges must be addressed for more eco-friendly coconut production. First, preventing the expansion of coconut plantations into sensitive ecosystems and protected areas is vital to preserve biodiversity and maintain ecological balance. , Second, ensuring fair wages, safe working conditions, and equitable trade practices in the coconut industry are crucial for sustainable and ethical coconut production. Third, identifying innovative ways to reduce waste during processing and exploring opportunities for recycling or upcycling coconut byproducts can contribute to a more eco-friendly supply chain.…”

This review investigates coconut as a sustainable and nutrient-rich plant-based alternative to traditional animal-based food sources. We have explored the nutritional profile, culinary versatility, particularly focusing on the use of coconut meat, milk, cream, and oil in diverse dietary contexts when consumed in balance. Comparative analysis with animal-derived products reveals the high content of medium-chain triglycerides (MCTs), essential vitamins, and minerals in coconut, contrasted with its lower protein content. Researchers have underscored the environmental sustainability of coconut, advocating for its role in eco-friendly food production chains. We have also addressed challenges like potential allergies, nutritional balance, sensory attributes, and consumer motivations for coconut-based products, in terms of understanding the market dynamics. In conclusion, this review positions coconut as a promising candidate within sustainable diet frameworks, advocating for further research to augment its nutritional value, sensory characteristics, and product stability, thereby facilitating its integration into health-conscious and eco-centric dietary practices.

“…The in vitro regeneration of oil palm polyembryoids has been successfully established via a vitrification-based cryopreservation method with a 45% survival rate [3]. Cryopreservation techniques are successfully used for the germplasm storage of commercial palms, such as oil palm, date palm, and coconut [18][19][20]. Until now, no further reports have been published on the improved cryopreservation protocols with a high survival or viability rate.…”

Oil palm (Elaeis guineensis) is the highest oil-yielding commercially grown perennial tree. Oil palm germplasm conservation and in vitro clonal propagation strengthened the world’s efforts to ensure future food security. Cryopreservation provides long-term storage for germplasm. The storage of plant material at cryogenic temperatures (−196 °C) following dehydration causes cryoinjury. The cryotolerance mechanism has rarely been studied in oil palm zygotic embryos (ZE) and embryogenic calli (EC). A simple and effective cryopreservation method was established for ZE. ZE surrounded by endosperm was air-dried for 3 days without any complicated chemical pre-treatments before cryopreservation, while the viability rate and following germination rate could reach up to 96.67% and 90.88%, respectively. As for EC, the preferred method could be pre-culture in liquid MS medium with 0.3 M sucrose for 12 h and PVS2 treatment for 5 min prior to cryopreservation, and the viability rate reached 68.33%. SSR markers were used to verify the genetic stability after cryopreservation. In addition, changes in enzyme activities (CAT, POD, and SOD) showed a consistent trend with H2O2 production among ZE samples, indicating that these antioxidants were involved in ROS scavenging. Furthermore, differently expressed genes (DEGs) related to ROS, osmotic, and cold stress responses were selected for correlation network analysis. Most genes involved in ROS production (RBOH, PAO, and PRX) and ROS scavenging (APX, PER, SOD, CAT, GPX, and AOX) showed higher expression levels in EC, suggesting that EC was more sensitive to oxidative stress than ZE. The cryotolerance mechanism was further summarized accordingly. These results contributed to cryopreservation methods and provided a better understanding of cryotolerance in oil palm.
