Leeds Spinout MicroLub Raises $10 Million to Scale Protein-Based Fat Reduction Technology

MicroLub, an ingredient technology company spun out of the University of Leeds, has completed a $10 million funding round led by Northern Gritstone. All existing investors took part, including NPIF II – PXN Equity Finance, managed by PXN Ventures as part of the Northern Powerhouse Investment Fund II.

Solving the reformulation trade-off

Food manufacturers face mounting pressure to improve the nutritional profile of their products, driven by tighter regulation, changing diets and the spread of GLP-1 medications, which have increased demand for higher-protein, lower-calorie foods.

The obstacle has always been sensory performance. Removing fat or adding protein frequently compromises the taste, texture and mouthfeel that drive repeat purchase. Conventional fat replacers based on starches, gums or alternative fats can deliver only part of the experience.

MicroLub takes a different approach. Its patented protein-based ingredient technology reproduces the lubrication that fat provides in the mouth using water, according to the company. MicroLub says this enables fat and calorie reductions of up to 75% while preserving the sensory experience consumers expect.

In many applications, the technology can also raise protein content and simplify ingredient lists by removing emulsifiers and thickeners, ingredients that a growing share of consumers try to avoid.

From laboratory to industrial scale

The company was founded by Professor Anwesha Sarkar of the School of Food Science and Nutrition at the University of Leeds, whose research focuses on the physics of how food feels in the mouth. MicroLub has since progressed from lab-scale work to industrial-scale manufacturing and reports that it is working with some of the world’s largest food and ingredient companies.

It continues to collaborate with the university’s research facilities while operating its own food innovation laboratory at the Nexus innovation centre in Leeds.

Use of funds

The new capital will support:

• Expansion of the team.
• Accelerated entry into the U.S. and Asian markets.
• Conversion of existing customer trials into commercial agreements.
• Further development of the proprietary ingredient platform.

Chief executive David Peters said the technology means consumers no longer have to choose between indulgent products and nutritious ones, and that the investment will help put MicroLub-enabled products on shelves soon. Duncan Johnson, chief executive of Northern Gritstone, described the company as tackling one of the food industry’s biggest scientific and commercial challenges.

Market context

Several regulatory and market forces are converging in MicroLub’s favour. In the UK, restrictions on the promotion and advertising of foods high in fat, sugar or salt are pushing manufacturers to reformulate. Globally, GLP-1 users are reducing portion sizes and seeking nutrient-dense foods, while clean-label preferences continue to penalise long ingredient lists.

Ingredient solutions that can address all three pressures simultaneously, lower fat, higher protein and fewer additives, without sacrificing eating quality, are in high demand across dairy, desserts, sauces, dressings, bakery and plant-based categories.

What to watch

The key test for MicroLub will be commercial conversion. Ingredient startups often spend extended periods in customer trials, and the speed at which large manufacturers move from pilot to full product launches will determine the company’s revenue trajectory. Cost-in-use, regulatory labelling in different markets and performance under industrial processing conditions will all influence adoption.

Backed by a well-funded university commercialisation investor and established academic research, MicroLub enters that phase with a strong technical foundation and a clear position in one of the food industry’s most active innovation areas.
