摘要
目的 利用低场核磁共振技术实现对市面上常见肉松种类的快速无损检测与识别。方法 本研究开发了一种适用于肉松制品种类快速检测的低场核磁共振二维弛豫指纹谱方法, 基于指纹谱色度差异区分肉松种类。结果 基于研发的二维弛豫指纹谱技术方法, 可对市面上常见的猪肉、鸡肉、牛肉、鱼肉及其混合肉松进行快速无损区分。随着肉松中不同成分比例的变化, 指纹谱展现出明显的定性变化趋势, 能够有效反映肉松中各类肉类的比例变化, 证实了该技术的精确性。 结论 本研究方法可以快速无损并精确地区分市面上大部分肉松种类, 能够满足食品行业和政府检测机构的需求, 是一种具有巨大前景的新型检测手段。
Abstract
Objective To achieve the identification and rapid detection of commonly found types of meat floss on the market via low-field nuclear magnetic resonance. Methods This study developed a low-field nuclear magnetic resonance two-dimensional relaxation fingerprinting technique suitable for the rapid detection of meat floss product types. Based on the colour discrepancy, different types of meat floss products can be distinguished. Results The developed two-dimensional relaxation fingerprinting technique can quickly and non-destructively distinguish between commonly available pork, chicken, beef, fish, and their mixed meat floss products.With the change in the proportion of different components in meat floss, the fingerprint spectrum shows a significant qualitative trend, effectively reflecting the changes in the proportion of various meats in meat floss, which proves the accuracy of this technology. Conclusion This research method can rapidly, non-destructively and accurately differentiate most types of meat floss on the market, meeting the needs of the food industry and government testing institutions, making it a promising new detection tool with great potential.
