COPENHAGEN, Denmark — The dieter’s dream of fat-free whipped cream has turn into a actuality — because of beer and crops?
College of Copenhagen researchers have changed milk fats with micro organism to create a prototype fat-free, sustainable whipped cream.
Presently, common whipped cream comprises 38 % saturated fats, required to offer the ethereal and stiff consistencies. To create another, the staff efficiently constructed on their work of utilizing lactic acid micro organism to kind tiny constructing blocks to create meals. They managed to supply each fluffy and stiff variations of the cream.
How did scientists make the brand new whipped cream?
Lactic acid micro organism are in every single place, inhabiting human and animal mucous membranes. They’re in digestive tracts, crops, and are generally used to create cultured yogurt and chilly cuts.
Although there are a variety of dairy-free whipped creams in the marketplace, they’re created utilizing saturated sources of fats imported from the tropics, corresponding to coconut and palm fats.
Furthermore, they include at the very least 25 % fats, are sophisticated to supply, and are full of E-number meals components.
“Whipped cream undergoes a novel transformation that happens in a posh system the place a excessive saturated fats content material makes it attainable to whip the cream stiff,” Risbo explains.
“So, how can we create another the place we keep away from the excessive fats content material, whereas nonetheless attaining the appropriate consistency? That is the place we have to suppose innovatively.”
“We normally affiliate micro organism with one thing to steer clear of meals. However right here, we base a beloved meals product on good bacteria present in nature. This has by no means been seen earlier than,” the researcher continues.
“That is advantageous, each as a result of it’s a renewable useful resource grown in a tank, and since it creates a more healthy, much less vitality dense, fat-free product.”
“Right here we solely use 4 components – water, micro organism, a little bit of milk protein and a single thickener. With these few components, we’ve managed to make a fat-free product that may be whipped, peaks up and retains the liquid,” Risbo says.
Making a template for dairy-free meals
The fats content material is so excessive as a result of fat globules in cream clump up as they’re whipped to create the ethereal foam. The froth then stabilizes to offer the required energy to maintain it standing up, with out the liquid draining out.
Researchers used two totally different lactic acid micro organism for the fluffy and stiff lotions, each roughly the identical dimension because the fats globules in dairy-based whipped cream.
One micro organism has a water-like floor which types a weaker community and produces a softer foam. The second is nearer to fats, forming stronger networks and a stiffer foam able to standing in tall peaks.
Professor Risbo notes their invention is to not create a stand-alone product but, however present perception into how meals might be created with out dairy.
“We’ve proven that micro organism can be utilized to create the appropriate construction. Now that we perceive the context and have discovered which floor properties are vital, it opens up the potential of utilizing many different issues from nature,” Risbo concludes.
“This may very well be yeast residue from brewing, or maybe small constructing blocks that we extract from crops. This is able to make the product very sustainable.”
The findings are printed within the journal Food Hydrocolloids.
