Ghee residue is the brown, crumbly solid left in the pan after butter or cream is clarified into ghee. It is mostly trapped ghee plus milk protein, milk sugar and minerals, browned by heat, and it can go into burfi, laddoo-style sweets, roti dough, halwa and bakes. Unlike ghee, it holds real moisture, so treat it as a perishable dairy food.

At a glance
- Ghee residue is the browned milk solids left after clarifying: in a 2023 NDRI study it was 52 to 68 per cent fat, 13 to 34 per cent protein, 9 to 14 per cent lactose and 10 to 15 per cent moisture.
- It browns through the Maillard reaction and caramelised lactose; samples went from light brown at 110 °C to darker brown at 120 °C.
- Researchers have made it into burfi, candy, chocolate, cookies, cakes and muffins; at home it goes into roti dough, halwa or a quick sweet.
- Its antioxidant activity and phospholipid content are test-tube and composition findings, not health effects.
- Unlike ghee, it holds real moisture, so refrigerate it covered and use it soon; blackened or sour-smelling residue goes in the bin.
What is ghee residue made of?
Ghee residue is the milk solids-not-fat from butter or cream, which heat coagulates and browns, together with ghee caught among them. Laboratory analyses find fat, protein, milk sugar (lactose), minerals (measured as ash) and some moisture. The balance shifts a great deal with the method of making ghee, the temperature and the milk.
FSSAI's standard defines ghee as milk fat made by processes that remove almost all the water and milk solids-not-fat, with no more than 0.5 per cent moisture and at least 99.5 per cent milk fat. The residue is where much of those removed solids end up. The best recent analysis we found is a 2023 study from ICAR's National Dairy Research Institute (NDRI) in Bengaluru, published in the Indian Journal of Dairy Science. It made ghee from the milk of indigenous Deoni cows and Holstein Friesian crossbred cows, by two methods and at two clarification temperatures, then pressed and analysed the residue.
| Component | Range in the 2023 NDRI samples | Range from older studies, as cited in the same paper |
|---|---|---|
| Fat | 51.6 to 67.7 per cent | 32 to 70 per cent |
| Protein | 13.5 to 34.2 per cent | 12 to 39 per cent |
| Lactose (milk sugar) | 9.4 to 14.2 per cent | 2 to 14 per cent |
| Moisture | 10.5 to 14.7 per cent | 8 to 30 per cent |
| Ash (minerals) | 1.9 to 5.6 per cent | 1 to 8 per cent |
| Phospholipids | 3.2 to 15.1 per cent | 1.5 to 17 per cent |
Each figure is the lowest and highest across different samples, so a column does not add up to 100. The paper does not state the basis for every figure, and some samples' components add to more than 100 per cent, so treat the numbers as broad guides. A commercial residue from a dairy plant, tested alongside and left out of the ranges above, was drier and lower in lactose, at 8.77 and 8.14 per cent, and higher in ash, at 7.15 per cent.
Why does ghee residue turn brown?
It browns because milk sugar and protein react under heat. The NDRI authors attribute the colour to the Maillard reaction, between sugars and the free amino groups of proteins, and to caramelisation of lactose. Hotter clarification produced more of the browning marker hydroxymethylfurfural (HMF), and samples went from light brown at 110°C to darker brown at 120°C.
Clarification temperature had a statistically significant effect on both HMF and a browning index measured from scanned colour values. Breed mattered too: residue from the crossbred cows' milk was browner than residue from Deoni milk, which the authors suggest may come from more free amino groups.
Our guide to making bilona ghee at home describes the point to stop: the solids at the bottom golden to light brown, with a nutty smell. That guide treats dark brown solids as a sign the ghee has gone too far, and blackened solids are not worth saving.
What did researchers find about its antioxidant activity?
In laboratory tests, methanol extracts of ghee residue neutralised a test chemical called DPPH, a standard measure of antioxidant activity in a test tube. Across the NDRI samples the activity ranged from about 27 to 68 per cent. This describes the chemistry of the material. It says nothing about any effect in the human body.
Two findings stand out. First, residue from creamery butter scored higher than residue from cream clarified directly, and it also carried more phospholipids, fat-like molecules that the authors link to the membranes around milk fat globules. The authors cite earlier work that names phospholipids as the main source of the activity, along with some amino acids and browning products. Second, the method of making ghee had a significant effect on antioxidant activity, while the breed of cow did not.
The phospholipid numbers explain why researchers are interested. The paper cites cow milk at about 0.2 to 1 per cent phospholipids, against 3 to 15 per cent in its residue samples. A study by researchers from the same institute and a food technology college in Andhra Pradesh, published in Waste Management in 2026, notes that industry treats the residue as a waste and channels it into low-value uses in animal feed. It tested microwave extraction with water to recover phospholipids, which can work as emulsifiers.
Does the way you make ghee change the residue?
Yes, markedly. In the NDRI study the method of making ghee significantly affected protein, fat, lactose, ash, phospholipids and antioxidant activity. Residue from creamery butter averaged about 31 per cent protein against about 21 per cent from direct cream, while direct-cream residue was fattier. Clarification temperature mainly changed moisture, lactose, ash and browning.
The authors put the protein gap down to curd particles carried over in the butter.
One limit matters for anyone making bilona ghee. The study used two methods: clarifying separated cream, and clarifying creamery butter made from aged cream. It did not test butter churned from curd, which is how traditional bilona ghee is made and how Himdhara makes its ghee, clarifying the butter slowly over a wood fire. Since method changes composition, do not assume the numbers carry over. Our comparison of bilona and cream-separated ghee covers how those methods differ.
How can you use ghee residue in the kitchen?
Use it where a sweet, nutty, milky crumb suits the dish. Dairy researchers have made it into burfi, candy, chocolate, cookies, cakes and muffins, and at home it can be kneaded into roti or paratha dough, stirred into halwa, or mixed with sugar or jaggery into a quick sweet. Strain it well first.
| Use | How to use it | Tested in a study? |
|---|---|---|
| Burfi | Cook the residue with khoa or roasted besan and sugar until it sets | Yes: burfi, candy and chocolate, Janghu and colleagues, 2014 |
| Cookies and biscuits | Replace part of the dough with residue | Yes: added at 10 to 30 per cent, Bajwa and Kaur, 1995 |
| Cake and muffins | Replace part of the flour with residue | Yes: a 60:40 flour-to-residue mix scored best, Ranjan and colleagues, 2020 |
| Roti or paratha dough | Knead a spoonful into the dough for a richer flatbread | No: kitchen use |
| Halwa | Stir it in near the end for a caramelised milky note | No: kitchen use |
| Quick sweet | Mix with powdered sugar or jaggery and nuts, then roll | No: kitchen use |
The tested products were judged by sensory panels. In the 2014 study, candy, chocolate and burfi scored between 7.12 and 7.92 out of 9 for overall acceptability. In the 1995 study, adding residue alone improved the cookies' colour, crispness and mouthfeel but made the surface finish worse, which the researchers improved with the additives glycerol monostearate or sodium stearoyl-2-lactylate. In the 2020 study, from Banaras Hindu University, cake and muffins with 40 per cent of the flour replaced by ghee residue scored best for colour, texture, taste and overall acceptability.
A few practical points:
- Strain and press it. Ghee left in the solids is ghee you can still use. Press the residue gently through muslin while it is warm.
- Remember it is already rich. At more than half fat in the laboratory samples, it can replace some of the fat in a recipe, not just add to it.
- Leave out burnt bits. Pick out any blackened pieces before you use the rest.
How should you store ghee residue?
Store it as a perishable dairy food, not as ghee. FSSAI allows ghee no more than 0.5 per cent moisture, while laboratory residue samples in the NDRI study held about 10 to 15 per cent, plus protein and milk sugar. We found no tested shelf life for homemade residue, so refrigerate it covered and use it soon.
- Cool it quickly. Spread the strained residue out so it cools, then move it to a clean, dry, covered container.
- Refrigerate it. Do not leave it in the pantry beside the ghee jar.
- Use it soon. Plan the dish before you make the ghee.
- Check before you cook. Sour, cheesy or rancid smells, or any mould, mean it goes in the bin.
In the 2014 study, burfi, candy and chocolate made with residue were stored for 30 days, and their free fatty acids rose significantly though they stayed within limits the authors considered acceptable. That was a laboratory study of products packed in polyethylene bags and glass containers, not a guide to how long a homemade sweet will keep. For the jar of ghee itself, see our article on ghee storage and shelf life.
The short version
Ghee residue is the browned milk solids left after clarifying butter or cream, and in laboratory samples it was roughly half to two-thirds trapped fat, with protein, milk sugar, minerals and some moisture. It browns through the Maillard reaction and caramelised lactose, more at higher temperatures. Its antioxidant activity and phospholipid content are test-tube and composition findings, not health effects. Use it in burfi, cookies, roti dough or halwa, keep it in the fridge, and use it soon.
