Abstract

The transition toward greener methodologies in analytical chemistry has intensified interest in biochar as a sustainable sorbent for food analysis. Derived from the pyrolysis of agro-industrial residues, biochar combines low-cost production with good properties such as high surface area, porosity, and surface tunability. This review provides a critical and feedstock-oriented overview of biochar applications in food sample preparation, categorizing sorbents based on their biomass origin (fruit waste, nut and seed residues, cereal by-products, lignocellulosic fibers, and wood waste). Each source is examined in terms of its physicochemical characteristics, extraction efficiency, and performance across different food matrices. Special emphasis is placed on sorbent modification strategies, the use of environmentally compatible desorption solvents, and the alignment of biochar use with green analytical chemistry (GAC) principles. Additionally, the review identifies key research gaps, limitations in analytical reproducibility, and challenges for regulatory acceptance. Overall, biochar emerges as a versatile and eco-efficient material with strong potential to enhance sustainability in food safety analysis.

天然吸附剂：生物炭材料作为绿色萃取方法在食品分析中的应用

在分析化学中向绿色方法的过渡已经加强了对生物炭作为食品分析的可持续吸附剂的兴趣。生物炭来源于农业工业残留物的热解，它具有低成本的生产和良好的性能，如高表面积、孔隙率和表面可调性。本文综述了生物炭在食品样品制备中的应用，并根据其生物质来源（水果废料、坚果和种子残留物、谷物副产品、木质纤维素纤维和木材废料）对吸附剂进行了分类。每个来源在其物理化学特性，提取效率和性能在不同的食品基质方面进行检查。特别强调的是吸附剂改性策略，使用环境相容的解吸溶剂，以及与绿色分析化学（GAC）原则对齐的生物炭使用。此外，该综述还指出了关键的研究差距、分析可重复性的限制以及监管接受的挑战。总的来说，生物炭作为一种多功能和生态高效的材料，具有强大的潜力，可以提高食品安全分析的可持续性。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
