Special Issue Information

Dear Colleagues,

The valorization of food residues represents a critical scientific and technological frontier in the context of global efforts to enhance sustainability, reduce food waste, and promote circular economy practices. This Special Issue of Applied Sciences seeks to gather high-impact, innovative research that addresses the transformation of agri-food by-products and processing waste into valuable ingredients, materials, or products through scientifically grounded approaches.

We invite original contributions that advance the understanding and application of food residue valorization in diverse areas, including sensory science, bioactive compound extraction and characterization, novel product development, green processing technologies, and other fields. Manuscripts should demonstrate methodological rigor, innovation, and relevance to real-world challenges in food systems, providing meaningful contributions to the scientific community and offering scalable, sustainable solutions.

Submissions that integrate interdisciplinary approaches and propose novel uses of underutilized raw materials are especially encouraged. The overarching goal is to promote scientific dialog and technological development that support global sustainability agendas, including the United Nations Sustainable Development Goals (SDGs).

This Special Issue aims to be a reference point for cutting-edge research that redefines waste as a resource and strengthens the role of science in building resilient, efficient, and environmentally responsible food systems.

Verjuice, a green grape juice traditionally produced from grapes obtained through thinning, represents a sustainable alternative for the utilization of viticulture by-products. No standardized methods of production are utilized to make verjuice, highlighting the need for further research. This study evaluated three extraction methods—pressing extraction (PE), steam extraction (SE), and centrifuge juicer extraction (CJE)—to produce verjuice from three Vitis labrusca varietals (Bordô, Concord, and White Niágara). Physicochemical parameters, volatile compounds (VOC), total polyphenol content, antioxidant and anti-hypertensive activities were analyzed. Extraction method and grape varietal influenced physicochemical composition, antioxidant capacity, and VOC. The SE method resulted in higher yields but lower polyphenolic content, while the CJE was more efficient in extracting phenolic compounds and preserving antioxidant properties. Higher concentrations of malic acid were observed in verjuice extracted by PE and CJE methods from Bordô and Concord grapes, while higher tartaric acid content was found in Bordô and Niágara grapes extracted by CJE. Within grapes, verjuices presented wider volatile profile than those described in the literature, and CJE and PE methods yielded higher amounts of VOC. Thus, V. labrusca presents great potential to produce verjuices and CJE shows to be an efficient alternative to the pressing method. Full article
