Fruits & Vegetables

Fruits and vegetables are essential sources of vitamins, minerals, fiber, and antioxidants, playing a crucial role in a healthy diet. However, they are highly perishable and susceptible to contamination by pesticides, heavy metals, microbial pathogens, and chemical residues. To ensure their safety and quality, the Food Safety and Standards Authority of India (FSSAI) has established parameters for their analysis. These parameters help in monitoring nutritional value, pesticide residues, microbial contamination, and adulteration to ensure compliance with food safety standards.

Parameters for Analysis as per FSSAI

These FSSAI-mandated parameters ensure that fruits and vegetables are safe for consumption, free from harmful contaminants, and meet quality standards. Regular monitoring and compliance with these regulations help in maintaining public health, preventing foodborne illnesses, and promoting sustainable agriculture practices.

Physicochemical Parameters

  • Moisture Content (%) – Determines freshness and shelf stability
  • pH Value – Indicates acidity or alkalinity
  • Total Soluble Solids (TSS) (°Brix) – Measures sugar content in fruits
  • Acidity (%) – Assesses tartness in fruits and vegetables
  • Ash Content (%) – Evaluates total mineral content
  • Specific Gravity – Determines the density of juice or pulp
  • Texture & Firmness – Assesses fruit ripeness and quality

Microbiological Analysis

  • Total Plate Count (TPC) – Measures overall microbial load
  • Coliform & E. coli Count – Indicates fecal contamination
  • Yeast & Mold Count – Detects fungal contamination
  • Salmonella, Listeria, Staphylococcus aureus – Pathogen testing
  • Anaerobic Spore Formers (Clostridium botulinum) – Checks for toxin-producing bacteria

Pesticide Residue Analysis

  • Organochlorine Pesticides (DDT, Aldrin, Heptachlor, etc.)
  • Organophosphates (Malathion, Chlorpyrifos, etc.)
  • Carbamates & Pyrethroids – Common insecticides used in agriculture
  • Glyphosate and Neonicotinoids – Herbicides and systemic pesticides
  • Multi-Residue Screening (MRLs as per FSSAI standards)

Adulteration & Chemical Contaminants

  • Calcium Carbide (for Artificial Ripening of Fruits)
  • Oxytocin (used in vegetables like pumpkin and gourds)
  • Wax Coating on Fruits (Edible vs. Non-Edible Waxes)
  • Synthetic Colors & Dyes (for appearance enhancement)
  • Non-Permissible Preservatives (Formalin, Sulfur Dioxide, etc.)

Nutritional Composition

  • Antioxidant Levels (Polyphenols, Flavonoids, Carotenoids)
  • Vitamin Content (Vitamin C, A, B-complex, etc.)
  • Carbohydrates (Sugar, Starch, Fiber)
  • Energy Value (Kcal per 100g)
  • Protein Content
  • Fat Content (if applicable)

Heavy Metal Contamination:

  • Lead (Pb)
  • Cadmium (Cd)
  • Arsenic (As)
  • Mercury (Hg)
  • Chromium (Cr)
