“…The determination of the chemical composition will allow us to better understand the possible uses of SCS. Although the value obtained for the ashes (1.31%) is higher than the values obtained for SCS by Venegaz-Gomez et al [47], Duman et al [15], and Kamel et al [48], with 0.24%, 1.16%, and 1.2%, respectively, the differences are not significant. The inorganic composition shows that SCS are more rich in potassium, with 3.2%, than all the other constituents, followed by calcium (Ca) and phosphorous (P), with 0.93 and 0.95%, respectively.…”

During the industrial processing of sweet cherry fruits, the seeds are considered agricultural waste and must be disposed of, typically through burning. In this context, it is intended to contribute to the scientific development of the ecovalorization of by-products and to provide new strategies for their transformation into value-added products obtained from sweet cherry seeds (SCS). This work aimed to establish the chemical characterization of SCS before and after several pre-hydrolysis steps in order to allow the solubilization of hemicelluloses that can later be used for the recovery of sugars. The higher percentage of cellulose and lignin remaining in the solid phase will allow its further processing for an integral valorization of the raw material. The temperature (160 and 170 °C) and time (0 and 180 min) of pre-hydrolysis were optimized to obtain the best liquefaction. The percentage of liquefied material was determined from the solid waste obtained at the time of filtration. The best liquefaction by the hydrolysis of SCS was obtained at 170 °C and 180 min, with a yield of 26.7%. The chemical analyses of SCS throughout hydrolysis showed the solubilization of hemicelluloses with increases in the time and temperature of the reactor. -cellulose and lignin showed an increase both with temperature and time, increasing the material’s potential for further processing in adhesives. FTIR analysis showed that there were significant changes in the spectra between the initial SCS, the solid residue, and the liquefied material. Pre-hydrolysis was proven to be an efficient process to improve the chemical composition of the material for further processing into adhesives or higher-mechanical-strength polyurethane foams.

“…On an industrial scale, this is usually accomplished using carefully chosen experimental parameters in order to obtain specific adsorbents from low-cost precursors with the minimum energy consumption. One suitable AC precursor is cherry stones (CSs, hereafter) [3][4][5], from which AC has been developed as usual by the two stages of physical and chemical activation methods. As far as the chemical method is concerned, ZnCl 2 [6,7], KOH [8,9] and H 3 PO 4 [10,11] have been used as activating agents for such a purpose.…”

The preparation of activated carbons (ACs) from cherry stones and chemical activation with H3PO4 can be controlled by the experimental variables during the impregnation step in order to obtain a tailored porous structure of the as-prepared ACs. This control not only extends to the ACs’ texture and porosity development, but also to the chemical nature of their surface. The spectroscopic and elemental characterization of different series of ACs is presented in this study. The spectroscopic band features and assignments strongly depend on the H3PO4 concentration and/or the semi-carbonization treatments applied to the feedstock before impregnation, which ultimately influence different characteristics such as the AC hydrophilicity. Different surface chemistries arise from the different tailored impregnation solutions, showing a practical outcome for future applications of the as-prepared ACs.

“…Cherry liquors are made by maceration processes, i.e., the fruit is mixed in its own spirit (37.5% up to 70% (v/v) ethanol), which is obtained by fermentation and subsequent distillation from cherry must (freshly squeezed cherry juice containing the skins, stones, and stems), obtaining the liquor with an alcoholic concentration of 15-17 • (v/v) [5]. During this practice, the stones are kept intact, being one of the main residues generated in the production of liquor [6]. Especially in The Jerte Valley (Extremadura, Spain), where more than 60 wt% of Spanish sweet cherry is produced (22,000 tons per year), it is estimated that approximately 143 tons per year of sweet cherry stone waste is generated during the production of Kirsch (cherry brandy) [6,7].…”

The integrated valorization of food chain waste is one of the most promising alternatives in the transition to a sustainable bioeconomy. Thus, an efficient solid-phase matrix dispersion extraction method, using experimental factorial design and response surface methodology, has been developed and optimized for the recovery of polyphenols from defatted cherry seeds obtained after cherry liquor manufacture and subsequent fatty acid extraction, evaluating the effect of each processing step on the composition and phenolic content of sweet cherry residues. The phenolic extracts before fermentation showed the highest content of total polyphenols (TPC) and flavonoids (TFC) (3 ± 1 mg QE·g−1 and 1.37 ± 0.08 mg GAE·g−1, respectively), while the highest antioxidant capacity was obtained in the defatted seed extracts after both fermentation and distillation. In addition, high-performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer (HPLC-ESI-QTOF-MS) was used to determine the phenolic profile. Dihydroxybenzoic acid, neochlorogenic acid, caffeic acid, and quercetin were the main phenolics found, showing differences in concentration between the stages of liquor production. The results underline the prospective of cherry by-products for obtaining phenol-rich bioactive extracts for possible use in different industrial sectors, offering a feasible solution for the cascade valorization of cherry agri-food waste.
