Benzo[a]pyrene (BaP), which is emitted during the processing of smoked sausages, accumulates in sausages and poses a serious threat to human health. This study focused on the removal of BaP from sausages and accompanying particulate matter (PM) during the smoking of sausages by films formed by combining corn starch (CS) with K-carrageenan (KC)/sodium alginate (SA). Initially, the effects of different additions of KC and SA on the rheological analysis, thermogravimetric analysis (TGA) and film-forming properties of the composite films were investigated. The BaP reduction capacities of CS-KC and CS-SA composite films in sausage were 41.1%-47.0% and 54.2%-56.5%, respectively, because the three-dimensional mesh structure of the composite films provided a large number of adsorption sites. Finally, kinetic studies demonstrated that BaP control in composite films is mainly achieved by intraparticle diffusion. Therefore, due to its excellent recyclability and biodegradability, composite starch film has a promising application in smoked meat products.
苯并[a]芘（BaP）在熏制香肠的过程中会被排放出来，它会在香肠中积累，并对人类健康构成严重威胁。本研究主要关注的是通过用玉米淀粉（CS）与κ-卡拉胶（KC）/海藻酸钠（SA）组合形成的薄膜，来去除香肠熏制过程中产生的 BaP 及其伴随的颗粒物（PM）。首先，研究了不同 KC 和 SA 添加量对复合膜的流变性分析、热重分析（TGA）和成膜性能的影响。CS-KC 和 CS-SA 复合膜在香肠中的 BaP 去除率分别为 41.1%-47.0%和 54.2%-56.5%，这是因为复合膜的三维网状结构提供了大量的吸附位点。最后，动力学研究表明，复合膜中 BaP 的控制主要是通过颗粒内扩散实现的。因此，由于其优异的可回收性和生物降解性，复合淀粉膜在熏制肉制品中有很好的应用前景。
