Acrylamide (ACR), a toxic by-product of high-temperature food processing, poses significant health risks due to its oxidative, neurotoxic, and genotoxic properties. Regulatory measures focus on limiting ACR in commercial food products, yet daily cooking practices often result in unnoticed exposure, threatening vulnerable populations such as children. This study evaluates the protective role of low and medium molecular-weight (MW) chitosan against ACR-induced toxicity using . Chitosan, a natural polysaccharide with antioxidant and prebiotic properties, was supplemented alongside ACR exposure in larvae and adult flies. Developmental metrics such as pupation rates, fecundity, and adult emergence were assessed, alongside oxidative stress markers and neurobehavioral outcomes. ACR exposure impaired development, increased oxidative stress, and reduced locomotor activity. Supplementation with low and medium MW chitosan alleviated these effects, with low MW chitosan demonstrating greater efficacy. These findings reveal the potential of low MW chitosan as a dietary intervention to counteract the toxic effects of contaminants like ACR. By reducing oxidative stress, preserving mitochondrial function, and supporting developmental processes, chitosan offers a promising avenue for mitigating the overall toxicity of heat-processed toxins. These findings further highlight chitosan's molecular weight-dependent protective potential against ACR toxicity, offering insights into its application as a dietary mitigator of heat-processed toxins.
丙烯酰胺(ACR)是高温食品加工过程中产生的一种有毒副产品,因其具有氧化、神经毒性和遗传毒性,会对健康构成重大风险。监管措施主要集中在限制商业食品中的丙烯酰胺含量,但日常烹饪过程往往会导致人们在不知不觉中接触到它,这对儿童等弱势群体构成了威胁。本研究使用……评估了低分子量和中分子量壳聚糖对丙烯酰胺诱导的毒性的保护作用。壳聚糖是一种具有抗氧化和益生元特性的天然多糖,在幼虫和成年果蝇接触丙烯酰胺的同时补充壳聚糖。评估了化蛹率、繁殖力和成虫羽化等发育指标,以及氧化应激标志物和神经行为结果。接触丙烯酰胺会损害发育、增加氧化应激并降低运动活性。补充低分子量和中分子量壳聚糖可减轻这些影响,其中低分子量壳聚糖显示出更高的功效。这些发现揭示了低分子量壳聚糖作为一种饮食干预措施来对抗丙烯酰胺等污染物毒性的潜力。通过降低氧化应激、维持线粒体功能和支持发育过程,壳聚糖为减轻热加工毒素的总体毒性提供了一条有前景的途径。这些发现进一步突出了壳聚糖对丙烯酰胺毒性的分子量依赖性保护潜力,为其作为热加工毒素饮食缓解剂的应用提供了见解。
