How Ghee Is Adulterated: Vegetable Oils and Vanaspati

Adulterated ghee is produced by blending cheap non-dairy fats like vanaspati, hydrogenated palm oil, or starches into milk fat alongside synthetic aromatic compounds and oil-soluble dyes. Because pure dairy fat requires significant amounts of fresh milk to produce, low-grade fat substitutes are often introduced into bulk supply chains to lower production costs. Adulterated ghee has been in the news recently, leaving home cooks curious about how fake dairy fat is made and how it behaves differently in the kitchen. Understanding the common additives used in adulterated batches makes it easier to evaluate what you bring into your home pantry.

How is commercial ghee adulterated?

Commercial fat adulteration relies on blending high-melting-point plant fats or animal tallow with small portions of genuine milk fat. Producers melt these low-cost fats together in large tanks and add liquid synthetic flavorings that smell like heated butter solids. Yellow oil dyes, such as coal-tar dyes or solvent-extracted pigments, are introduced to match the golden hue of authentic cow ghee. Once stirred and cooled, the resulting mixture looks and smells remarkably similar to pure ghee at room temperature, making visual inspection inside a sealed tub difficult for retail buyers.

Why are hydrogenated vegetable oils added to fake ghee?

Hydrogenated vegetable oil, commonly sold as vanaspati, is the primary additive in adulterated ghee because its solid fat structure mirrors dairy fat at room temperature. Through partial hydrogenation, liquid vegetable oils become firm, semi-solid fats that do not separate easily into oil layers when stored on pantry shelves. When vanaspati is blended into real butterfat, it thickens the jar and holds a uniform appearance. However, vanaspati melts at a higher temperature than natural milk fat, leaving a heavy, greasy film on the palate when consumed on warm roti or mixed into hot cooked grains.

What role do animal fats and starches play in ghee adulteration?

Boiled potato starch, corn flour, tallow, and lard are used to add bulk, weight, and density to substandard fat batches. Starches absorb excess moisture in wet butter solids and create a thick consistency that mimics slow-cooked dairy fat. While starches increase the weight of a batch at negligible cost, they alter how fat reacts to heat in the pan. When heated, starch-laden fat scorches quickly, sticks to hot iron skillets, and produces a cloudy sediment rather than clarifying cleanly into liquid golden oil.

Our cows are not use and throw

A cow that stops giving milk is still our cow. She stays on the farm, with the same feed, the same shed and the same medical care she had when she was milking. We do not sell her on and we do not let her go. That is the whole basis of the ghee we make — you cannot ask an animal for her milk and then abandon her for it.

Our mission goes further than our own herd. There are cows on the street who are injured every day, who eat plastic, who cry through the night with nobody coming. We want to take them in. The plan is a chain of Organic Farmz gaushalas in several places, so that help is not one shed in one city but something a hurt animal can actually reach.

This takes more than we can carry alone — land, fodder, vets, hands. Come and join our initiative. Anything you give goes to feed, treat and shelter these cows.

How do adulterators match the aroma and grain of real ghee?

Synthetic chemical compounds like diacetyl are added to fake fat batches to mimic the rich, toasted nut aroma of slowly clarified butter fat. To replicate the granular texture, known as danedar texture, manufacturers cool hydrogenated fats slowly under controlled temperatures or add small amounts of coarse wax particles. While this creates a grainy appearance inside a sealed container, these artificial grains behave unnaturally when warmed. Pure grains formed by slow curd churning melt instantly at body temperature, whereas artificially structured grains resist melting and leave a sticky coating on fingers and utensils.

How does traditional bilona processing prevent adulteration?

Traditional bilona processing uses whole cultured curd churned in wooden pots to separate butter fat, creating distinct physical characteristics that blended fats cannot replicate. Because bilona ghee comes from hand-churned cultured makhan rather than industrially separated cream, its protein solids brown gently during open-pot boiling. This yields natural aromatic compounds and a soft, uneven grain structure that forms organically as the pot cools down. You can perform simple heat and palm tests at home to observe how authentic milk fat melts cleanly under mild heat without leaving residue behind.

What should you look for when buying ghee to ensure purity?

Ensuring purity when buying ghee requires checking for farm traceability, unblended milk sources, glass packaging, and transparent processing methods. Genuine bilona ghee lists a single ingredient on its label: milk fat derived from cow or buffalo milk. It features a soft, golden color, a mild dairy aroma that lingers naturally without smelling harsh or perfumed, and a clean melt when stirred into warm rice, roasted lentils, or hot flatbreads. Buying direct from small-batch producers who manage their own herds offers clear visibility into how every jar is churned and clarified.
