New ‘Butter’ Spread Made of Almost 80% Water

New ‘Butter’ Spread Made of Almost 80% Water

Butter spread with low calories and lipid content discovered. The new 'butter' consists mostly of water and less fats and tastes the same compared to conventional butter.

A tablespoon of this low-calorie spread has 2.8 grams of fat and 25.2 calories. Butter, on the other hand, which is 84% fat and about 16% water, has about 11 grams of fat and nearly 100 calories.

They figured out a new process to emulsify a large amount of water with minuscule drops of vegetable oil and milk fat to mimic butter, at approximately one-fourth the calories of real butter and without artificial stabilizers.

"Imagine 80% water in 20% oil, and we create something with the consistency of the butter, with the mouthfeel of butter and creaminess of the butter," said food science professor and senior author Alireza Abbaspourrad.

Emulsifying water and oil is nothing new, said Abbaspourrad, but by using high-internal phase emulsions (HIPE), "we keep adding water to that oil until the final composition is 80% water and 20% oil."

The demand for low-fat, high-protein products has rapidly increased due to consumers' growing health awareness, said lead author Michelle C. Lee, a doctoral candidate in Abbaspourrad's research group.

"Since the HIPE technology features high water-to-oil ratios - while simultaneously delivering unique texture and functionality - it can play a role in providing healthier solutions for consumers," Lee said.

Abbaspourrad said food chemists could adjust for taste, preferences, and health.

"We can add milk protein or plant-based protein, and since the water acts as a carrier, we can adjust for nutrition and load it with vitamins or add flavors," he said. "Essentially, we can create something that makes it feel like butter - and instead of seeing a lot of saturated fat, this has minute amounts. It's a completely different formulation."

In addition to Abbaspourrad and Lee, co-authors on the research, "Ultrastable Water-in-Oil High Internal Phase Emulsions Featuring Interfacial and Biphasic Network Stabilization," include postdoctoral researcher Chen Tan and doctoral candidate Raheleh Ravanfar. Support for this research came from the New York State Dairy Promotions Board.
