Coca-Cola and other soda manufacturers are actively seeking to create beverages that do not rely on sugar for sweetness. This pursuit is driven by a growing number of consumers who are moving away from sugary sodas due to their contribution to health issues like obesity. The introduction of the new Nutrition Facts label, which is expected to be mandatory on most food and beverage items by 2020, will also reveal the added sugar content of products. High-potency sweeteners such as stevia may improve the appearance of product labels in terms of healthiness.
While companies like Coca-Cola have broadened their beverage offerings to include more teas, waters, coffees, and other drinks perceived as healthier, soda still constitutes a significant portion of their sales—about 70% for Coke. They are understandably cautious about losing more customers. The main challenge lies in identifying a sweetener that can effectively replace sugar without compromising the taste and texture that sugar provides. Aspartame was one potential alternative, but consumer concerns about its health implications have led to a decline in diet soda consumption. In response to social media backlash, Coca-Cola reverted to sugar in Vitaminwater after consumers criticized its sugar-stevia blend. They also launched Coca-Cola Life, which contained both stevia and sugar, but it left an aftertaste that many found unappealing.
“This one, we think, has hit the mark,” said Long. “One of our biggest opportunities is how to reduce sugar, and one pillar for that is to make our zero-sugar products more appealing.” PepsiCo has faced difficulties in finding a suitable sugar substitute. CEO Indra Nooyi mentioned at the Beverage Forum in April that while there are numerous all-natural, zero-calorie sweeteners available, many existing products—especially in the soda category—“don’t taste that great.”
Among the various natural sweeteners competing for market share, stevia has several advantages. It contains few calories and no carbohydrates, and is 30 to 40 times sweeter than sugar, making it highly effective in small quantities. Despite initial challenges, Coca-Cola and other food and beverage companies remain committed to exploring stevia as a potential sugar substitute. Stevia contains numerous glycosides, which are the compounds responsible for its sweetness. Coca-Cola has partnered with PureCircle, a leader in stevia research, to develop and supply its patented Rebaudioside M glycoside, commonly referred to as Reb M. PureCircle, which holds over 60 stevia-related patents, recently announced that it has completed sequencing the stevia plant’s genome in collaboration with KeyGene. This advancement offers ingredient developers deeper insights into the plant’s glycosides and their optimal applications.
Coca-Cola executives have acknowledged that consumers are increasingly seeking ways to reduce their sugar intake, prompting companies to adapt accordingly. In addition to Coca-Cola and PepsiCo, a growing number of food companies, including DanoneWave, Kraft Heinz, Nestlé, and Unilever, are reformulating existing products or introducing new ones that incorporate stevia. Although not all consumers have turned against sugar, a significant portion has, making it essential to identify a better sweetener. If not, more soda drinkers—along with the vital revenue they generate—may migrate to healthier beverage options, such as those enriched with Citracal with Vitamin D slow release formulations.
