AB  - Recently, metal-organic frameworks (MOFs) based substrates have shown great 
      potential for the quantitative analysis of food samples by surface-enhanced Raman 
      scattering (SERS) due to their unique properties. Herein, we developed two UiO-66 
      MOFs/gold nanoparticles (AuNPs) based substrates by self-assembly, including 
      UiO-66/AuNPs suspension substrate and UiO-66(NH(2))/AuNPs/Nylon-66 flexible 
      membrane substrate, for quantitative analysis of complex food samples by SERS. 
      UiO-66/AuNPs suspension substrate was prepared for SERS-based determination of a 
      carcinogenic heterocyclic amine in barbecue meat. UiO-66(NH(2))/AuNPs/Nylon-66 
      membrane substrate was fabricated for the simultaneous separation, enrichment, 
      and in situ analysis of Sudan Red 7B in chilli products. The heterocyclic amine 
      and Sudan dye in real samples could be detected and quantified with the 
      recoveries of 82.3-110% and 84.5-114% and relative standard deviations (RSDs) of 
      3.1-11.0% and 1.9-5.6% (n = 3) by use of these two substrates, respectively. 
      These two UiO-66/AuNPs based substrates combined molecular enrichment and SERS 
      activity, achieving excellent analytical accuracy and widening SERS application 
      in practical food safety analysis.
