The Critical Thesis: In a high-demand market, the adulteration of Castor Oil with cheaper vegetable oils (like Rice Bran or Soy) is a “Ghost” that haunts procurement. Standard refractive index tests are no longer sufficient to catch modern, sophisticated adulteration.
The Deep-Dive Insight: The key is not in the oil itself, but in the Sterol and Tocopherol Fingerprint. Every castor seed grown in the Jamnagar-Kutch belt has a specific “biological signature” of micronutrients. Adulterators can mimic the viscosity of castor oil by using synthetic thickeners, but they cannot mimic the specific ratio of Brassicasterol to Campesterol inherent in the Ricinus plant.
The Original Conclusion: Nova Industries is advocating for High-Resolution Gas Chromatography (HRGC) as the new global standard for “Pure Castor.” We are building a database of the “Gujarat Fingerprint” to ensure that when a customer buys “High Purity,” they are protected by science, not just a promise. Purity is not a percentage; it is a biological identity.
