Chemists create chocolate with half the fat

Chocoholics have been looking for the answer for years: Chocolate + ? = Cellulite-free thighs.

We just never thought chemists would be the ones to solve the equation.

Researchers in the United Kingdom have managed to cut the amount of fat needed to make chocolate in half, without losing any of the dessert’s delectable-ness. Their trade secrets were published in the Journal of Materials Chemistry this week.

The new chocolate formula contains small droplets of fruit juice, explains lead study author Dr. Stefan Bon. These droplets can replace up to 50% of the triglyceride fats found in cocoa butter and milk, similar to the way air bubbles reduce the density of Aero chocolate bars.

Apparently the optimal size for these bubbles is less than 30 micrometers – allowing the fat to be replaced without losing the proper chemical structure.

“It's the fat that gives chocolate all the indulgent sensations that people crave – the silky smooth texture and the way it melts in the mouth but still has a 'snap' to it when you break it with your hand,” Bon said in a press release. "We've found a way to maintain all of those things that make chocolate 'chocolatey' but with fruit juice instead of fat.”

Bon and his chemistry colleagues at the University of Warwick used a process called Pickering emulsion to infuse orange juice, cranberry juice and de-carbonated soft drinks into milk, dark and white chocolate.

(Emulsion is the mixing of two liquids that can’t be mixed – like oil and water. Pickering emulsion occurs when solid particles are added to keep the mixture in place, rather than having them separate out naturally.)

While the texture of the new product feels the same as regular chocolate, Bon told CNN in an e-mail, the taste is understandably a bit fruity. In the future scientists could use water with a small amount of vitamin C to replace the fruit juice flavor.

The study is just the first step to healthier chocolate - the food industry still needs to jump on board the fruit juice train.

“The process for introducing the droplets is easy,” Bon wrote. “It would be great if the technology will lead to new innovative chocolate-based products.”

    Great! Now we can eat more chocolate and get more sugar in our diet.

      Chocolate usually contains added sugar. The fruit juice can replace some of that added sugar so that the total sugar content will stay the same. The researchers also say that water + vitamin C can be used in the future

      >> Chocolate usually contains added sugar. The fruit juice can replace some of that added sugar so that the total sugar content will stay the same.

      No. Fruit juice contains fructose, which is the worst kind of sugar. At least the sucrose added to regular chocolate has glucose, which can be metabolized in more than just the liver.

      The article is just all wrong, and the chemists who came up with this nonsense are wrong to demonize fat. Wake up people.

    • This is great

      Steve: Fruit juice contains glucose, sucrose and fructose. In fact, orange juice contains about 25% glucose, 50% sucrose, and 25% fructose. High fructose corn syrups used in chocolates contain about 50% glucose and 50% fructose. But I think we are missing the point here. There are several unkowns, and without knowing the actual numbers in the final product it is pointless to debate about the effect of sugar. Also, if the researchers manage to replace fruit juice with Water + vitamin C, then at the very least, the sugar content should stay the same

      Also, a chocolate with 50% less fat without compromising taste and texture is a great achievement. There are plenty of sources of fat in today's world. It is upto the individual to pick and choose, and i think this chocolate will be a great choice. There is no right or wrong amount of fat in a chocolate, it depends on how you make it.

      Lastly, moderation is the key. Anything in excess is not good.

      This is so backwards... it's not the fat that is unhealthy – it's the sugar. Sugar is toxic, causes weight gain, metabolic dysfunction, and systemic inflammation, while on the other hand most saturated fats are a healthy source of clean-burning energy for the body.

    Chocolate consumption does not cause "cellulite". Although there are literally thousands of products that claim to reduce the dimpling of fatty areas around the thighs and associated body parts, none have been scientifically proven to work. The dimpling is more
    visible in overweight persons, but the main cause of so-called cellulite is hereditary and lack of exercise may exacerbate its appearance. So ladies, 90% of you will have dimpled spots somewhere at some age just because you are women (your physical makeup and heredity ), So enjoy a little dark chocolate without guilt.

      I've lost quite a bit of weight, about 22 pounds, and still eat small portions of dark chocolate every day. I cut out soft drinks, fried food, most carbs, and try to eat as much organic food as possible. I exercise about 15-20 minutes a day, my doctor says I should double that amount. I look like I did 15 years ago, but with more muscle mass. And the dark chocolate is good for my heart, in moderation.

    It’s cocoa butter, not trans fats. And they replace it with high fructose corn syrup? Regular dark chocolate is good for the gut bacteria (http://caloriesproper.com/?p=1583); I wonder if the added sugar will negate those beneficial effects.

      Where did you get high fructose corn syrup from in this article? They said they replaced fat with fruit juice. Fruit juice does not have HFCS unless it is added to it.

      The de-carbonated soft drinks would (likely) have high fructose corn syrup unless they were more organic. The orange juice or cranberry juice sound like much better options. I am a chocolate/orange combination fan so I am totally on board with this.

      It's the contributions of chemists which have allowed us to slow food spoilage (fighting hunger) and eliminated many food and water born diseases (created by God?). Not to mention chemists (such as myself) who spend their lives producing medicinal substances which fight all sorts of other naturally occuring diseases, disorders, and illnesses.

    Ugh! The fat in chocolate is what is good for you. People should be replacing the sugar in their chocolate with – wait for it – more chocolate or more accurately cocoa. Eat 70% or higher with more fat and less sugar and good to go. Another example of industrialization of our food and the negative health effects. So anyone that thinks this is a good thing is wrong.

    Poor article! If health is the goal, then maybe it should have addressed some basic health assumptions. I am not sure adding more sugar to chocolate has ANY health benefits whether it lowers calories or not. Fruit juice is just a way of adding sugar to products. Also, I am surprised that the article did not address Cocoa content. Does this process change that seems like an important question.

    CNN's prize Sanjay Gupta did just did a 60 minutes special focusing on sugar as a toxin that might be a major direct cause of Heart Disease and Cancer.

    Mixed messages? Or is a fruity, slightly lower calories snickers our goal?

    Not to be a stick in the mud...but the problem is not choclate it is eating too much of it. One small chochlate of any type (normal or reduced fat) will be absoltely fine as a nice treat. However, if you gorge on it, or eat candy by the bag, it's going to be a problem. Just do things in moderation and you'll be fine.

      Please define "moderation". There is a lot of room between one small chocolate and a whole bag. One small chocolate seems like a lot less than "moderation" to me, it sounds more like "a tiny bit." And how many episodes per day of one small chocolate still counts as "moderation"? Until "moderation" is defined, "Just do things in moderation and you'll be fine" is pretty useless.

      I eat lots of things in moderation. Chocolate, movie popcorn. For me it means being aware of how many calories I can consume in a day without gaining weight. Everyday I sit down and work out my planned calories in and make sure I get enough fiber, protein and vitamins using a free website. If breakfast, lunch, dinner and a snack meet my nutrient needs and I have left over calories I am allowed to have chocolate or anything else I like. I weigh myself daily and maintain a spreadsheet and daily food log. I think it would be more honest to admit up front that "in moderation" really means "take responsibility for yourself and know your body". Some people need to put more thought into the process then others but recommending people to eat in moderation is still a good tip.

    Chocolate is made of a cocoa bean (a vegetable), beet, cane or corn sugar (all vegetables) and vegetable oil (um, a vegetable), ergo:
