Abstract

Viha (Typhonodorum lindleyanum) presents a promising avenue for enhancing food security and addressing malnutrition in Madagascar, particularly in the face of climate change. This study comprehensively characterized the nutritional and phytochemical properties of Viha, considering the impact of processing methods on its edibility and potential health benefits. Our findings reveal a diverse nutritional profile across Viha plant parts. Rhizomes, rich in carbohydrates, exhibited significant variations in micronutrient content depending on cooking methods. Steaming enhanced iron and potassium, while boiling reduced calcium and phosphorus. Viha seeds demonstrated a relatively stable micronutrient profile across preparations, while leaves were rich in potassium, phosphorus, and iron. Furthermore, the study identified a rich array of phytochemicals, including tannins, flavonoids, and leucoanthocyanidins. While the presence of antinutrients such as phytate and oxalate requires careful consideration, appropriate processing methods can mitigate their impact. These findings suggest that Viha, with proper processing and utilization, could serve as a valuable food source, enhancing dietary diversity and nutritional security, especially in regions vulnerable to climate change impacts such as droughts and food shortages. Further research is warranted to optimize processing methods, enhance nutrient bioavailability, and explore sustainable cultivation and utilization strategies for Viha as a climate-resilient food source in Madagascar.

Abstract

This study meticulously investigates the chemical and nutritional profiles of two underexplored tropical fruit species indigenous to Madagascar: the Ceylon Gooseberry (Dovyalis hebecarpa) and the Cape Gooseberry (Physalis peruviana). Characterizing such native species is vital for diversifying food sources and enhancing nutritional security, particularly in biodiversity-rich regions.Systematic analyses performed across various plant compartments, notably their foliage, revealed a significant richness in essential micronutrients. Leaves of both species demonstrated substantial concentrations of potassium, phosphorus, iron, magnesium, and aluminum. Furthermore, Physalis peruviana leaves exhibited a particularly significant protein content, elevating their prospective utility beyond fruit consumption. This robust nutritional profile reinforces their potential as valuable, locally sourced ingredients to foster balanced diets in the region. Parallel to the nutritional assessment, empirical processing trials were initiated to ascertain the technological feasibility and quality attributes of derived products, focusing on wine. The fermentation processes consistently yielded wines categorized as dessert wines, which demonstrated stable physicochemical characteristics and promising shelf-life properties. This intrinsic stability, coupled with their unique profiles, suggests compelling added value within agro-food valorization strategies. Collectively, these findings underscore the considerable potential of both Dovyalis hebecarpa and Physalis peruviana for the innovative development of novel food products. Such initiatives not only contribute to agricultural diversification but also align seamlessly with circular economy principles by utilizing underexploited plant parts, and sustainable development by fostering local biodiversity and resource efficiency. This research provides a scientific basis for promoting the cultivation and processing of these indigenous fruits, contributing to economic growth and environmental stewardship.
