Citrullus lanatus (watermelon) is a fruit with remarkable therapeutic potential, as each part of itrind, peel, flesh, and seeds contain bioactive compounds. Despite its wide range of benefits, the utilization of watermelon, particularly its rind, remains limited due to a lack of awareness and an underrated perspective. The rind, situated between the green outer peel and the red flesh, is light green in color and rich in bioactive compounds, minerals, and phytochemicals. These constituents are associated with various therapeutic properties, including antioxidant, antineoplastic, cardiovascular, and neuroprotective effects. In addition to its therapeutic applications, watermelon rind offers significant commercial value in the food, cosmetic, and pharmaceutical industries, as well as in industrial applications such as biofuel production and eco-friendly packaging. Its versatility makes watermelon rind an exciting area of research for uncovering new applications and enhancing existing ones. However, limitations in its usage and handling need to be addressed for its broader adoption. This review comprehensively discusses the global research conducted to date on the nutritional composition, therapeutic potential, environmental impact, and commercial applications of watermelon rind. Additionally, it highlights challenges and future directions for advancing the utilization of this promising resource.

This study developed pectin nanocellulose (PNC) composite films using pectin extracted from watermelon rind and nanocellulose (NC) derived from pineapple peel. Films were prepared by incorporating varying NC concentrations (2 %, 5 %, 7 %, and 10 %) into the pectin matrix and characterized for optical, barrier, mechanical, thermal, and biodegradation properties, as well as their effectiveness in extending the shelf life of fresh-cut cauliflower. Fourier Transform Infrared Spectroscopy (FTIR) confirmed NC integration into the pectin matrix.

This study assessed the impact of partially replacing wheat flour in croissants with 10% or 15% orange peel (OP), watermelon rind (WR), or melon peel (MP) on sensory properties, in vitro antioxidant capacity (DPPH, total phenolics, flavonoids), and anti-hyperlipidemic activity in rats. Nine groups of rats: a control group (G1), a hyperlipidemic (G2), control diet + 40% croissants (G3), and hyperlipidemic diet and croissants enriched with 10% or 15% of OP (G4, G5), WR (G6, G7), and MP (G8, G9), respectively. OP exhibited the highest antioxidant activity, total phenolics, and flavonoids.

This study aimed to develop fresh pasta (FP) with improved functional properties by incorporating watermelon by-product powders (WBP), including watermelon peel powder (WPP), watermelon rind powder (WRP), and watermelon seed powder (WSP). FP samples were formulated with varying substitution levels (0%-15%) using durum wheat semolina, water, and egg. Physicochemical analyses revealed that WPP and WRP above 10% increased moisture content, while WSP reduced it.

Cherry tomatoes, consumed worldwide, have a short shelf life and are highly susceptible to significant pre- and postharvest losses, largely due to fungal pathogens like Alternaria alternata and Fusarium oxysporum. With the growing demand for nutritious food products free from synthetic preservatives, biopreservation has emerged as a safe and reliable method for controlling fungal growth in food. Biopreservation using lactic acid bacteria (LAB), known for producing antimicrobial metabolites, presents a promising approach at both the farm and industrial scales.
