英文摘要:

      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.
