Walnut milk residues (WMR) were investigated for the first time through their phenolic characterization including soluble (free, esterified, and etherified) phenolics those released from insoluble-bound form (insoluble-bound hydrolysates, IBPHs) antioxidant properties. Free recovered alkaline or acid hydrolysis used to recover remaining fractions. Total compounds (TPCs) activity analyzed by Folin–Ciocalteu, FRAP, ORAC methods, respectively. Soluble (free + esterified etherified fractions) showed a higher TPC (275.3 mg GAE 100 g−1 dw) (FRAP: 138.13 µmol TE dw; ORAC: 45.41 with respect IBPH. There was significant correlation between FRAP values regardless of fraction tested sample. Phenolic acids flavonoids identified quantified ultra-performance liquid chromatography–electrospray tandem mass spectrometry (UPLC-ESI-MS/MS). Gallic acid, mainly in free (3061.0 µg g−1), most representative, followed biochanin A, walnut product mostly present (593.75 g−1). No detrimental cytotoxic impact on Caco-2 cells observed. Hence, WMR could be considered potential source development nutraceutical and/or food additives.

Background Post-harvest storage of natural almonds is a critical step, as it can cause the onset microbial contamination and modify polyphenolic composition almond skin, potentially altering antioxidant capacity overall, health effects native product. This study aims to evaluate impact different post-harvest conditions on microbiological stability, profile, activity ( Prunus dulcis cv. “Fascionello”). Methods Natural were obtained from Consorzio Mandorla di Avola stored under three conditions: light exposure at room temperature (RT), dark RT, 4°C, monitoring relative humidity. Samples analyzed four time points (T 0 , T 3 6 9 months). Microbiological stability was assessed using standard plate-counting techniques; content determined through spectrophotometric assays RP-LC-DAD-ESI-MS/MS analysis, whereas evaluated spectrofluorimetric including DPPH, TEAC, FRAP, ORAC assays. Chemometric analyses performed compare changes across over time. Results Temperature remained stable with moderate variations, indicating well-controlled environment, while humidity exhibits significant fluctuations, likely influenced by external factors. No detected throughout storage, confirming safety almonds. The significantly decreased within first months, particularly RT. However, recovery phase observed cold-stored retaining highest levels total polyphenols flavonoids. skin extracts correlated content, showing an initial decline followed stabilization refrigerated storage. Hierarchical clustering highlighted distinct expression patterns based points. Conclusion profile properties For short-term (≤6 months), RT controlled sufficient preserve polyphenols, cold are recommended maintain bioactive compound potential for long-term (>6 These findings provide valuable insights optimizing strategies in food, nutraceutical, pharmaceutical industries.
