Because of the wide use of chromium-containing feed, much hexavalent chromium (Cr(VI)) tends to accumulate in pork. In order to decrease the toxicity of Cr(VI)-containing pork for human beings, high-energy electron beam (HEEB) irradiation was used to reduce highly toxic Cr(VI) to low toxic trivalent chromium (Cr(III)) in lean, fat, and marbled pork. HEEB irradiation could efficiently and nondestructively reduce both free and adsorbed Cr(VI) in pork, achieving the highest reductive efficiency (RE) of 98.03%. Therein, hydrated electrons (eaq- ) and hydrogen radical (•H) generated during the irradiation process probably played key roles in the reduction. The effects of irradiation dose, initial concentration of Cr(VI), pH, temperature, salinity, and oil on the RE were investigated to obtain the optimal reduction conditions, proving the high universality of this approach. This work provides a clean and low-cost method for removing Cr(VI) from pork, which is important to ensure food safety. PRACTICAL APPLICATION This work describes a facile, nondestructive, and clean method for removing Cr(VI) from meat product, which may have a potential application prospect in ensuring food quality and safety.

高能电子束辐照一步法无损还原猪肉中的Cr(VI)

由于含铬饲料的广泛使用，许多六价铬（Cr(VI)）容易在猪肉中积累。为降低含Cr(VI)猪肉对人体的毒性，采用高能电子束(HEEB)辐照，将瘦肉中剧毒的Cr(VI)还原为低毒的三价铬(Cr(III))。 ，脂肪和大理石花纹猪肉。HEEB辐照可以有效且无损地还原猪肉中游离和吸附的Cr(VI)，最高还原效率(RE)为98.03%。其中，辐照过程中产生的水合电子（eaq-）和氢自由基（•H）可能在还原过程中起关键作用。研究了辐照剂量、Cr(VI)初始浓度、pH、温度、盐度和油对稀土的影响，以获得最佳还原条件，证明了这种方法的高度普遍性。这项工作为从猪肉中去除 Cr(VI) 提供了一种清洁且低成本的方法，这对于确保食品安全非常重要。实际应用 本工作描述了一种简便、无损、清洁的去除肉制品中 Cr(VI) 的方法，在确保食品质量和安全方面具有潜在的应用前景。
