That’s not cookie dough — it’s a meat alternative created with a 3D printer and plant-based ingredients, including cocoa butter. Credit: Adapted from ACS Food Science & Technology 2021, DOI: 10.1021/acsfoodscitech.1c00311
No longer just a dream of vegetarians and vegans, fake meat is becoming more widely available in grocery stores and restaurants. And more options are almost certainly on the way. In a study reported in ACS Food Science & Technology, one team has developed a new combination of plant-based ingredients tailored for 3D printing meat alternatives. Their most successful recipes required an odd-sounding addition: cocoa butter, derived from cocoa beans of chocolate fame.
From animal welfare to environmental sustainability, there are plenty of reasons people choose to avoid eating meat derived from animals. Many current meat alternatives rely on plant-based proteins, most often from soy and wheat, which can readily mimic the texture and nutritional value of the real thing. While 3D printing has already been tested for meat alternatives, none of the current formulations include proteins from these particular plants. So, Songbai Liu and Shanshan Wang wanted to figure out an approach to making a meat “dough” with soy and wheat protein that could be produced effectively with a 3D printer.
The researchers tested soy and wheat proteins in formulations containing several other ingredients using a 3D printer. They evaluated their concoctions based on the accuracy with which the dough could be laid down by the printer and how well it held its form. They also examined its texture and microstructure.
The experiments revealed the importance of several additional ingredients, including the emulsifier Tween-80 and sodium alginate to control the texture. Heat-sensitive cocoa butter turned out to be a particularly important ingredient, making the dough more fluid at warm temperatures for printing, but then hardening afterward at room temperature, allowing the dough to retain its printed shape.
One drawback, however, is that people who cannot eat wheat gluten or soy because of allergies or celiac disease would not be able to partake of the new alternatives. To address this issue, the researchers attempted to replace the soy protein with that from peas, but the resulting dough was too soft for printing. Even so, these experiments have identified a new strategy for formulating meat alternatives using this versatile technology, according to the researchers.

Why did the vegan cross the road?
To get to the other side to tell you “I am a vegan.”
Uh, no.
True!
Never a semi load of logs around when you need it.
I’ll skip the soy, the grasshoppers, the tofu, and the laboratory-grown cells.
You may not have that choice...................
The dirty little secret is, if you do the research....fake meat isn’t anymore healthy than real meat....and in many ways not AS healthy.
Remember.....SOYLENT GREEN IS PEOPLE!
tofu is pretty good deep fried in bacon fat
I wonder if the vegans will cry when various species of tropical native trees are ripped out to make room for more cocoa trees...
Nope, no way, no how!
Oh, goody!
We’re already using more cocoa than can be sustainably produced, just to try to meet the global chocolate demand. There’s no bandwidth in the product stream to add fake meat.
I don’t eat Frankenfoods.
No thank you, I want my chocolate to taste like chocolate and when I eat meat, let it be real 100% bacon, steak, roasts, ribs, chicken, fish, etc.
Soylent $#!+.
