摘要:

为研究现有砖茶降氟措施的效果和存在的问题,通过采用文献分析、实地考察和实验验证相结合的方法,系统地评估了茶树种植、茶叶采收、毛茶生产、砖茶生产和饮茶环节中各类降氟措施的可行性和有效性。经过系统的分析和实验验证发现:在茶树种植环节筛选低氟品种茶树、在茶叶采收环节控制采摘时间可以有效控制砖茶源头氟含量;在砖茶加工过程中采取水淋洗方式能一定程度降低茶叶氟含量;在饮茶环节采用科学的饮茶方式,可以减少砖茶中氟的人体摄入量。磷酸钙和羟基磷灰石是安全高效的氟吸附材料。改善茶园种植环境、采用水潦青工艺、渥堆环节添加降氟材料等降氟效果不显著。针对存在的问题提出了重新审视和调整现有降氟研究策略、建立跨学科团队开发新的降氟技术、加强茶树品种选育工作、推广科学饮茶方式、制定综合降氟策略等建议,砖茶降氟措施研究需进一步提升评价的科学性,增强实际推广应用的可行性,并充分考虑措施对砖茶品质与安全的影响。研究旨在推动砖茶降氟研究的策略转变和思路拓展,为相关政策的制定和实施提供参考。

Abstract:

This paper aims to summarize and scientifically evaluate the effectiveness of existing fluoride reduction measures, providing validation and reference for further research on fluoride reduction strategies. This paper employed a combination of literature analysis, field investigations, and experimental validation to systematically assess the feasibility and effectiveness of various fluoride reduction measures at different stages, including tea tree cultivation, tea leaf harvesting, raw tea production, brick tea production, and tea consumption. Through systematic analysis and experimental validation, it was found that selecting low-fluoride tea tree varieties during cultivation and controlling the harvest time during tea leaf collection effectively reduced the fluoride content at the source. The water washing process during brick tea production was able to lower the fluoride content in the tea leaves to some extent. Additionally, adopting scientifically recommended tea-drinking practices reduced the fluoride intake from brick tea. Calcium phosphate and hydroxyapatite were identified as safe and effective fluoride adsorption materials. However, fluoride reduction effects were not significant when improving tea garden environments, using water blanching techniques, or adding fluoride-reducing materials during the pile fermentation process. Research on fluoride reduction measures in brick tea needs to further enhance the scientific evaluation process, improve the feasibility of practical applications, and fully consider the impact of these measures on the quality and safety of brick tea.
