中文摘要:

      随着消费者健康意识的提升, 果汁市场销售水平呈现快速增长态势。作为世界各地消费的重要饮料, 果汁已成为最常见的掺假目标之一。掺假果汁不仅对消费者的身体健康构成了直接的潜在威胁, 增加患病风险, 严重损害其健康权益, 更扰乱了市场秩序, 导致恶性竞争。因此果汁掺假检测技术逐渐成为研究热点。本文根据对样本影响程度的不同, 将果汁真伪鉴别技术分为有损和无损两大类, 从同位素分析、元素分析、色谱技术、光谱技术、智能感官技术、数字成像技术等多个方面, 汇集了果汁掺假检测技术大量的研究成果, 概述了各种掺假检测技术的原理、应用、优势以及局限性。在果汁掺假检测中, 与有损技术相比, 无损技术具有样品制备简便、操作易用、成本较低、便携性强以及无需使用试剂等优点。但要将技术运用于工业实践, 还需要结合生产需要, 以建立适用工业检验鉴定的模型。

英文摘要:

      The fruit juice market has shown rapid growth in sales levels as consumers become more health conscious. As an important beverage consumed around the world, fruit juice has become one of the most common targets for adulteration. Adulterated fruit juice not only poses a direct potential threat to consumers’ health, increasing the risk of illness and seriously harming their health rights and interests, but also disrupts the market order and leads to vicious competition. Therefore, fruit juice adulteration detection technology has gradually become a research hot spot. According to the different degree of impact on the sample, this paper divided the fruit juice authentication techniques into two categories: Destructive and non-destructive. This paper bringed together a large number of research results on juice adulteration detection techniques from isotope analysis, elemental analysis, chromatographic techniques, spectroscopic techniques, intelligent sensory techniques, digital imaging techniques, etc., and outlined the principles, applications, advantages and limitations of various adulteration testing techniques. In juice adulteration detection, compared with the destructive techniques, the non-destructive techniques had the advantages of simple sample preparation, easy operation, lower cost, high portability and no need for reagents, etc. However, in order to apply the technology to industrial practice, it is necessary to establish a model applicable to industrial inspection and identification in combination with production needs.
