03

Nutrition & Specialized Matrices

  • HFSS & Nutri-Score: Compliance testing for “High Fat, Salt, and Sugar” front-of-pack labelling.
  • Plant-Based & Alternative Proteins: Specific testing for meat analogues, lab-grown meat, and insect-based foods.
  • Bioactive Markers: Quantification of polyphenols, flavonoids, and specific active markers in nutraceuticals.
  • Vitamins (Fat & Water Soluble): Stability testing across the product’s shelf life to meet tighter FSSAI tolerance limits.
04
