Innovative Ways to Utilize Ghee Residue in Food Products

Every time ghee is prepared – whether in a rural household or a large dairy plant – a brownish, aromatic mass is left behind after the clarified fat is filtered out. This is ghee residue (also called ghee sediment), and most of it ends up as waste. That is a significant loss, because ghee residue is packed with proteins, healthy fats, minerals, and bioactive compounds that can add real value to a wide range of food products. In India alone, ghee residue production is estimated at roughly 0.2 million tonnes per year, and much of it remains underutilized. Let’s look at the many ways this overlooked dairy by-product can be put to work in the food industry.

What exactly is ghee residue? 🔗

During ghee manufacturing, cream or butter is heated until the water evaporates and the milk solids separate from the pure fat. These separated solids – a moist, light-to-dark brown sediment – are what we call ghee residue. Its composition typically ranges from 12-39% protein, 32-70% fat, 2-14% lactose, and 1-8% ash, depending on the raw material and the method of preparation (direct cream, creamery butter, or desi butter method).

The thermal treatment during ghee boiling triggers the Maillard reaction between amino acids and reducing sugars. This reaction gives ghee residue its characteristic nutty aroma, caramelized flavour, and brown colour. It also generates antioxidant compounds – particularly phospholipids, tocopherols, and browning reaction products – that have functional importance in food formulations. In addition, ghee residue contains valuable minerals such as calcium, phosphorus, and several flavouring compounds like carbonyls, lactones, and free fatty acids.

Use of ghee residue in sweets and confectionery 🔗

One of the most promising areas for ghee residue utilization is the confectionery sector. The natural sweetness, rich dairy flavour, and smooth texture of processed ghee residue make it an excellent ingredient for both traditional Indian sweets and modern confections.

Traditional Indian sweets 🔗

Ghee residue has long been used – though in limited quantities – in preparing traditional sweets. Research carried out at NDRI Karnal demonstrated that ghee residue can be successfully incorporated into burfi, a dense, condensed-milk-based sweet popular across India. The residue acts as both a flavouring agent and a protein booster in the final product. Similarly, sweets like sandesh and peda benefit from the authentic dairy flavour that ghee residue provides.

Candy and chocolate 🔗

When ghee residue is processed to reduce its fat content and improve texture, it can serve as a natural milk-solid substitute in chocolate and candy manufacturing. Its antioxidant properties help slow down rancidity in these products, while its emulsifying characteristics (due to high phospholipid content) improve mouthfeel in items like cream-filled chocolates. Research has shown that candy and chocolate prepared with ghee residue score well on sensory evaluation for flavour and overall acceptability.

Ghee residue in bakery products 🔗

The bakery industry offers numerous opportunities for ghee residue incorporation. Its properties as a natural emulsifier, protein source, and flavour enhancer make it a versatile ingredient.

Cakes and muffins 🔗

Studies have found that replacing a portion of refined wheat flour (up to 40%) with ghee residue in cake and muffin recipes improves their protein and calcium content without compromising sensory quality. In fact, higher levels of ghee residue led to better sensory acceptability in terms of flavour, colour, texture, and mouthfeel.

Cookies and biscuits 🔗

Ghee residue can also function as a partial fat substitute in cookie recipes (at around 10% replacement level), reducing overall fat while adding protein and natural antioxidant protection. The caramelized, nutty notes from ghee residue complement the flavour profile of biscuits and crackers, giving them a richer, more premium taste.

Bread and rolls 🔗

Incorporating processed ghee residue into bread dough can improve texture, boost protein content, and extend shelf-life. The residue acts as a natural dough conditioner, making it a practical addition for commercial bread production.

Edible pastes and fillings 🔗

Ghee residue can be processed into edible pastes suitable for use as fillings in sandwiches, samosas, and dosas. Research has explored formulations where ghee residue is combined with supporting ingredients like salt, chatni powder, or yeast-based flavourings to create pastes with good taste and spreadability. These pastes offer a high-protein, nutrient-dense alternative to conventional fillings and can be tailored for both savoury and mildly sweet applications.

Enhancing everyday foods: chapatis and snacks 🔗

Chapati and flatbread 🔗

Adding processed ghee residue to wheat flour for chapati preparation is a simple yet effective way to boost the protein content and improve texture of this daily staple consumed by millions. The residue also extends the shelf-life of the flatbread by acting as a natural conditioning agent.

Savoury snacks 🔗

Popular snacks like samosas, pakoras, and other fried items can incorporate ghee residue in their fillings or coating mixtures. This addition not only provides extra protein but also creates a richer, more satisfying flavour. Researchers at NDRI have developed ghee residue-based snack formulations combining the residue with skim milk powder, dry mango powder, baking powder, spice mix, salt, and rice flour.

Pinni: a traditional example of successful utilization 🔗

Pinni is a traditional North Indian sweet made at facilities like the NDRI model dairy in Karnal. Its recipe uses wheat flour, ghee, ghee residue, sugar, tragacanth gum powder, and dry fruits. The wheat flour is cooked and combined with dry fruits and ghee residue, then cooled before adding sugar and tragacanth gum. This approach has a dual benefit: it increases the yield of pinni while reducing the amount of additional ghee needed in the recipe, making production more economical.

Protein-rich energy bars 🔗

One of the more innovative recent applications is the development of protein-rich energy bars from ghee residue. A study published in 2025 optimized a formulation using approximately 32% ghee residue and 23% liquid sugar, combined with oats, wheat flakes, almonds, dates, and milk protein concentrate. The resulting energy bar contained about 20.82% protein, 15.28% crude fibre, and 377.70 kcal per 100 g, with a shelf-life of 45 days at room temperature. This demonstrates how ghee residue can be effectively used in modern convenience foods that appeal to health-conscious consumers.

Non-food applications worth noting 🔗

While the focus here is on food products, it is worth mentioning that ghee residue also has non-food applications. These include use as a supplement in animal feed (for poultry, fish, and pig diets), as a feedstock for biodiesel production, and as a substrate for microbial lipase production. Such diverse applications further underscore the economic value locked within this by-product.

Why commercial utilization remains underdeveloped 🔗

Despite its clear nutritional and functional potential, the large-scale commercial use of ghee residue is still limited. Several factors contribute to this gap.

Lack of awareness 🔗

Many small-scale and even some large dairy processors are simply unaware of the economic and nutritional value of ghee residue. This knowledge gap prevents the development of supply chains and partnerships needed for commercial viability.

Standardization challenges 🔗

The composition of ghee residue varies significantly based on the source milk, processing conditions, and preparation method. The yield itself ranges from about 3.7% in the creamery butter method to 12% in the direct cream method. This variability makes it difficult for food manufacturers to rely on ghee residue as a consistent ingredient without standardized processing protocols.

Limited shelf-life 🔗

Unprocessed ghee residue has a relatively short shelf-life (approximately 3 months when clarified at 120°C), which complicates logistics, storage, and distribution. Advanced processing techniques – like drying, powdering, or microencapsulation – can extend shelf-life but require investment in appropriate technology.

Infrastructure gaps 🔗

Effective utilization of ghee residue at an industrial scale requires dedicated processing equipment, quality control systems, and cold chain infrastructure. Many small and traditional ghee producers lack access to these resources.

The way forward: research and development priorities 🔗

To unlock the full potential of ghee residue, focused research and development efforts are essential. Key areas include developing standardized processing protocols to ensure consistent quality, exploring microencapsulation technologies to protect sensitive nutrients while controlling their release in food products, and investing in energy-efficient processing methods such as enzyme-based extraction that are both economical and environmentally friendly.

There is also a need for product diversification – moving beyond traditional sweets and bakery items to create contemporary food products like protein bars, health drinks, and fortified ready-to-eat meals that can reach a wider consumer base. Government support through schemes and awareness campaigns can help bridge the infrastructure and knowledge gaps that currently hold back large-scale adoption.

Ultimately, converting ghee residue from a disposal problem into a valued ingredient supports the circular economy model in dairy processing – reducing waste, creating additional revenue streams for manufacturers, and providing consumers with more nutritious food products.

What do you think? With India generating hundreds of thousands of tonnes of ghee residue annually, how can the dairy industry be incentivized to invest in its utilization rather than treating it as waste? Could ghee residue-based products find a place on mainstream supermarket shelves alongside conventional protein bars and health snacks?
