乙醇作为一种关键分析物，其精准检测在多个领域至关重要。在酿酒行业，乙醇含量是评价酒类品质的核心指标，关乎产品质量控制与消费者健康。在司法与交通安全领域，血液乙醇浓度是界定酒后驾驶与醉酒驾驶的法律依据。此外，在果蔬采后生理学中，乙醇水平是监控贮藏品质、评估保鲜处理（如适宜浓度的乙醇处理可延缓衰老、抑制病害）效力的重要参数，实现其简便、快速的测定对延长产品货架期具有实际意义。 其检测通常采用高效的酶偶联比色法：乙醇在乙醇脱氢酶（ADH）催化下氧化为乙醛，同时将氧化型烟酰胺腺嘌呤二核苷酸（NAD⁺）还原为NADH。生成的NADH在电子中介体1-甲氧基-5-甲基吩嗪硫酸甲酯（1-mPMS）存在下，进一步还原水溶性四唑盐WST-8，生成橙黄色的甲臜产物。该产物在450 nm波长处有特征吸收峰，通过测定此波长下吸光度的上升速率，即可精确计算出样品中乙醇的含量。
Ethanol serves as a critical analyte, and its precise detection is essential across multiple fields. In the brewing industry, ethanol content is a core indicator for evaluating the quality of alcoholic beverages, directly impacting product quality control and consumer health. In the legal and traffic safety sectors, blood ethanol concentration provides the legal basis for defining drunk driving and impaired driving. Furthermore, in postharvest physiology of fruits and vegetables, ethanol levels serve as an important parameter for monitoring storage quality and assessing the effectiveness of preservation treatments (for instance, appropriate ethanol treatments can delay senescence and inhibit disease). Achieving simple and rapid measurement of ethanol has practical significance for extending product shelf life. The detection typically employs an efficient enzyme-coupled colorimetric method: ethanol is oxidized to acetaldehyde under the catalysis of alcohol dehydrogenase (ADH), while simultaneously reducing oxidized nicotinamide adenine dinucleotide (NAD⁺) to NADH. In the presence of the electron mediator 1-methoxy-5-methylphenazinium methyl sulfate (1-mPMS), the generated NADH further reduces the water-soluble tetrazolium salt WST-8, producing an orange-yellow formazan product. This product exhibits a characteristic absorption peak at a wavelength of 450 nm. By measuring the rate of increase in absorbance at this wavelength, the ethanol content in the sample can be accurately calculated.
