What makes ice cream so addictive cw39 houston electricity in homes


Whatever the reason, I know I’m not the only person that has regular cravings for ice cream. According to the International Dairy Foods Association, the average American consumes more than 23 pounds of ice cream per year. That’s more calories than we’ll ever want to know.

“When you get the answer to that, will you call me and let me know?” joked Steve Young, a consulting food chemist and microbiologist, and a former technical director at Dreyer’s and Edy’s Grand Ice Cream, who teaches courses on ice cream science and technology to the very people who make ice cream, including at Breyer’s and Ben and Jerry’s.

According to Young, helping ice cream manufacturers produce ice cream with a high appeal for consumers “is the study of a lifetime.” That’s because it involves “a lot of applied chemistry and physics,” he explained, along with “heavy doses of personal preferences.” For example, Young notes, “I love coffee … but if you put it in ice cream format, I can’t stand it.”

As the co-author of “Tharp & Young on Ice Cream: An Encyclopedic Guide to Ice Cream Science and Technology,” he knows a bit more about what goes into making decadent ice cream than he let on. Unsatisfied with Young’s non-answer, I pushed until he finally offered me at least a hint at what makes ice cream so delectable. The ‘F-factor’

Paying careful attention to temperature during delivery is key, because if ice cream melts and refreezes during distribution and storage, this can damage the air cell structure and create large ice crystals, which can negatively affect the texture of ice cream, Young explained. Sweetness: The biggest driver of the ‘F-factor’

The No. 1 driver of ice cream cravings is its sweetness, explained Gail Civille, founder and president of Sensory Spectrum, a consulting firm that helps companies learn how sensory cues drive consumer perceptions of products. Ice cream should not be “cloyingly sweet — so you can eat more of it,” Civille said.

“The more butterfat, the better the mouthfeel,” said Deanna Simons, the quality manager of Cornell’s Dairy Bar, which produces premium ice cream on campus, including flavors such as Kahlua Fudge and Triple Caramel Bliss. Having a lower overrun, a term that refers to the amount of air incorporated into ice cream, also contributes to an appealing mouthfeel, according to Simons.

So, sweetness — which contributes to the taste variable — and fat — which contributes to texture and triggers that you’ve eaten something substantial — are key players in the likability of any particular ice cream. But Civille also points to another interesting food characteristic that plays a very important role in an ice cream’s appeal: control over melt.

“The melting [of ice cream] gives an additional sensory experience unlike other types of foods, because you don’t get the same transformation [from other foods],” explained Alina N. Stelick, a scientist who runs sensory tests on ice cream at Cornell University’s Sensory Evaluation Center.

To better understand the concept of melt, thinks of “mix-ins,” such as chocolate chips or nuts. “The ice cream acts as the lubricant,” Civille explained. “The ice cream matrix needs to melt slowly enough so you can get at the pieces and chew them and get rid of them before the ice cream is completely gone.”

Aside from sugar, fat and melt, companies may use differing amounts and types of ingredients to affect the different flavor variables. For example, a manufacturer might use egg yolk in an ice cream recipe, which may contribute a yellowish color and custardy or “eggy” flavor to ice cream.

Irresistible ice creams are also made with high-quality ingredients. For example, making ice cream with good milk (the source of milk fat and milk solids) is a very important, explained Stelick. “The milk should have a ‘very light sweet taste’ — clean dairy notes without any extraneous off-taste or off-flavors,” she said. If a dairy case is lit with LEDs, for example, oxidation in milk may occur, which can make milk taste like plastic, she explained.

Here’s where ice cream’s complexity gets even more interesting: Young explained how you can have all the formula and flavor specifics of the very best-selling ice cream, and yet there’s no guarantee that another ice cream meant to “copy” that very same best-seller would taste the same. In other words, there’s something uniquely consistent about what any given brand produces, what it sells and “how it eats” — a technical term that refers to how the ice cream behaves while it is warmed during chewing.

Because of this, Civille goes as far as dividing ice cream “addiction” into two parts: One is, you can be “addicted” to the frozen treat — all of its general flavor attributes, including creaminess and sweetness. But you can also be “addicted” to a particular brand.

One of Civille’s projects entailed helping a large ice cream company match its original imported vanilla as its primary ice cream flavor. The company wanted to guarantee that it wouldn’t lose the quality of the vanilla flavor when it had to substitute the original vanilla for another kind.

“A brand of Madagascar vanilla may no longer be available, and so what are you going to do now? You may have to substitute a Tahitian vanilla or use another supplier,” Civille said. As an aside, she explained that a lot of vanillas are “fake.” “Vanilla should taste like cooked butter, cooked milk and caramel, not fake caramel with artificial butter notes,” she said. The scoop on serving sizes

If there’s any good news to come out of our affinity for ice cream, maybe it’s the fact that the government is finally recognizing what a serving of ice cream actually is, or should be. Right now, the serving size of ice cream on food labels is listed as half a cup, but it will soon be changing to a more realistic two-thirds of a cup.
