随着工业化步伐的加快和农业活动的密集化，地质条件、气候变化以及环境污染等多重因素相互作用，使得稻谷镉（Cd）超标问题突出，对粮食安全和人体健康构成了极大威胁。Cd作为一种有害的重金属元素，其在稻谷中的累积不仅降低稻米品质，还可能经由食物链进入人体，诱发慢性中毒等健康问题。因此，探索安全、高效、绿色且经济的方法清除受污染稻谷中的Cd元素，并开展Cd污染稻谷的高值化利用，在新质生产力发展背景下备受关注。本文全面回顾了多种清除技术在降低稻谷Cd含量方面的成效，深入剖析了这些技术的作用机理、适用场景、成本效益等多个维度。同时，本文还详细阐述了Cd污染稻谷产后高值化利用技术，这些技术不仅可以有效削减Cd含量，更着眼于提取并高效利用稻谷中的有益成分，从而实现资源价值的最大化。高值化利用技术不仅具备一定的经济效益和环境效益，还能为相关行业开辟新的原材料来源，推动产业链的拓展与升级。此外，本文指出了未来行业研究的重点方向。

With the acceleration of industrialization and the intensification of agricultural activities, the issue of cadmium exceeding the standard in rice has become increasingly prominent due to the intertwined effects of geological conditions, climate change, and environmental pollution, posing a serious threat to food safety and human health. As a toxic heavy metal, cadmium accumulation in rice not only affects the quality of rice but also may enter the human body through the food chain, leading to chronic poisoning and other health problems. Therefore, exploring safe, efficient, green, and economical methods to remove cadmium from contaminated rice grains and developing high-value utilization technologies for cadmium-contaminated rice have become research topics of great concern in the context of the development of new productive forces. This paper comprehensively reviewed the effectiveness of various removal technologies in reducing cadmium content in rice grains, deeply analyzed their mechanisms of action, applicable scenarios, cost-effectiveness, and other dimensions. At the same time, this paper also elaborated on high-value utilization technologies for cadmium-contaminated rice post-harvest, which not only aim to effectively reduce cadmium content but also focus on extracting and efficiently utilizing beneficial components in rice grains, thereby maximizing resource value. These high-value utilization technologies have certain economic and environmental benefits and can provide new raw material sources for related industries, promoting the extension and upgrading of the industrial chain. Moreover, this paper identifies the key directions for future industry research.
