This study investigated the innovative incorporation of Artocarpus altilis leaves into potato-based gnocchi, demonstrating a sustainable approach to valorizing underutilized plant materials. Breadfruit leaves, often discarded as agricultural waste, represent an untapped resource rich in bioactive compounds and antioxidants. By incorporating these leaves into pasta products, we demonstrate a promising strategy for enhancing food systems’ nutritional profile and sustainability. The research examined the functional, pasting, and bioactive properties of Artocarpus altilis leaf blends with potato flakes. The blends showed significant water-holding capacity (4.88–8.58 g H₂O/g DM) and notable antioxidant activity in both aqueous and ethanolic extracts (DPPH: 1.95–3.35 mg TE/g DM). Pasting profiles revealed that increasing the Artocarpus altilis concentration progressively modified the starch behavior, reducing the peak viscosity from 972.5 to 530.0 mPa·s. Gnocchi formulated with 10% Artocarpus altilis leaves demonstrated good stability during 4-day storage, with minimal color changes (ΔL* ≈ 2) and predictable textural evolution (cutting force increase from 4.5 to 5.8 N). The incorporation of these leaves enhances the nutritional profile through increased antioxidant content and promotes sustainable food production by utilizing agricultural by-products. This approach demonstrates the potential for developing eco-friendly food products while supporting local agricultural economies in tropical regions with abundant Artocarpus altilis. The successful integration of these leaves into a popular food product opens new possibilities for sustainable food innovation and waste reduction in the food industry. Full article

Breadfruit (Artocarpus altilis) is a traditional fruit tree of 15–30 m tall in Oceania. The species is a staple crop for food security in the tropics. Tree loss from tropical windstorms, together with transition toward high-density planting has driven an interest in the dwarf phenotype of the species. Information on dwarfing rootstocks for breadfruit is currently limited. The aim of this study was to assess the performance of breadfruit growth with lakoocha (Artocarpus lakoocha) as rootstocks. We compared the phenotype of breadfruit trees on lakoocha rootstocks with those on self-graft and non-graft within 21 months after grafting. These led to the discovery of a rootstock-induced dwarf trait in breadfruit species. Breadfruit scions on lakoocha rootstocks displayed a reduction in tree height, stem thickness, and internode length, with fewer branches and leaves, resulting in about 32% of the standard height at the end of 21 months after grafting. These suggest lakoocha rootstocks have the potential to control breadfruit tree vigor. Non-structural carbohydrate analysis showed the composite trees exhibited lower hexose concentration in both scion stems and roots, but higher sucrose level in scion stems, and higher starch level in roots. The significance of these parameters in rootstock dwarfing is discussed. Full article

Breadfruit (Artocarpus altilis) is a tropical fruit tree primarily grown as a staple crop for food security in Oceania. Significant wind damage has driven an interest in developing its dwarf phenotype. The presence of any dwarf breadfruit variety remains unknown. Little is known regarding the growth of the species on rootstocks. Here, we examined the phenotype of breadfruit plants growing on marang (Artocarpus odoratissimus) rootstocks within 18 months after grafting; we identified a rootstock-induced dwarf trait in the species. This dwarf phenotype was characterized by shorter stems, reduced stem thickness and fewer branches, with 73% shorter internode length, 51% fewer and 40% smaller leaves compared to standard size breadfruit plants. The height of breadfruit plants on marang rootstocks was reduced by 49% in 9 months, and 59% in 18 months after grafting. The results suggest marang rootstocks can be applied to breadfruit breeding program for tree vigor control. Further biochemical characterization showed plants on marang rootstocks displayed leaves without change of total chlorophyll content, but with lower total soluble sugars, and stems with reduced activity of plasma membrane H⁺-ATPase, a well-known primary proton pump essential for nutrient transport. The significance of the two parameters in rootstock dwarfing is discussed. Full article
