The definition of a healthful beverage is driven by whether the consumer perceives the product to be “better-for-you,” says Gary Hemphill, senior vice president of the Beverage Marketing Corporation (BMC, New York). This definition can include those products that have added beneficial ingredients, or have had undesirable ingredients removed. Regardless of whether the product is perceived as healthful, its success still is dependent upon the product's flavor, texture and tangible benefits.
For Prepared Foods' 2005 “Functional Foods Survey” (see PF's April 2005 issue), some 67% of respondents who work with beverages ranked them as the category that offered the greatest opportunity for the development of functional foods. “In terms of growth, the area of health and wellness is the best place to be--from a beverage standpoint,” says Hemphill. “It is relatively underdeveloped, and more and more consumers are adopting healthier lifestyles.”
Evolving from EvianIn the 80s, consumers who had limited beverage options drove the demand for healthful beverage alternatives. With Evian (The Danone Group, Fribourg, Switzerland), the U.S. saw the introduction of the first single-serve, bottled water. It paved the way for premium, single-serve fruit beverages that address consumers' taste for increased variety and products with a “better-for-you” halo.
With the consumer at the helm, manufacturers started removing ingredients that were perceived as unhealthy, and placed more emphasis on diet or carbonated soft drinks with lower calories. The formulation of healthful beverages today includes the addition of ingredients with a healthy aura. “We think that is going to evolve even more so,” says Hemphill.
Healthier versions of carbonated soft drinks, fruit beverages, bottled waters, bottled and canned ready-to-drink (RTD) teas, sports drinks, RTD coffee, energy drinks and value-added milk-type products steadily are penetrating the market. Some 64% of PF beverage respondents characterized their future functional food product development efforts as “brand new products.”
Today's consumers have higher expectations for tangible benefits, as opposed to benefits that are more “perceived” than “real,” explains Hemphill. “Oxygenated water and beverages with Ginkgo biloba are examples of a product that has the 'healthy halo' but doesn't necessarily deliver…in a proven, scientific way.”
Caffeine is an example of an ingredient that has real benefits in teas and energy drinks, but consumers have mixed sentiments in regards to their attitudes toward it. White tea, another example, is a hot segment of the tea category, as is green tea. “There is more segmentation in the marketplace. As the category starts to develop or mature, consumers become more sophisticated about the category and want more variety,” adds Hemphill.
Examples are Honest Tea's (Bethesda, Md.) Mango White Tea, an organic white tea with acai and packed with a “double serving” of antioxidants. Consumers are trending toward teas with fewer calories and a lighter taste profile. Yet, they are still a small part of the RTD tea picture. “Tea is a very good antioxidant. It blends well and has a very gentle flavor, meaning it can accept flavors readily,” says Gerry Blight, a supplier of vitamins, antioxidants and beverage flavor blends.
The trend toward fortification with calcium and other vitamins is becoming popular in the area of nutritional enhancement of beverages (including juices and carbonated soft drinks), says Blight.
Unique flavor systems, such as Land O' Lakes' (Dean Foods, Dallas) 80 'N Sunny blended juice and milk products, are becoming more popular. Fast food chains are marketing smoothies, also. “Smoothies are great because they can increase fruit intake,” says Blight. In addition, they tend to stabilize more easily, allowing food manufacturers to process and distribute them with less fuss than some milk-based beverages. Blight says he likes the combination of dairy and fruit juice because it gives a whole new direction to the category, opens consumers' eyes to innovative products, and offers a new area of competition for beverage companies.
“We are on a threshold of a broad expansion of beverages--similar to what was seen years ago with granola bars [in the choice of breakfast foods],” he adds. “Beverages seem to be a more universal option than nutritional snacks. There are dozens of nutritional bar options but, with beverages, there are literally thousands of options.”
There is a definite advantage to fortifying beverages as opposed to other prepared food applications. Drinks are easy to formulate, in that many nutrients are easily dispersed within an aqueous system. Besides the solubility factor, however, our bodies contain more fluids than anything else, explains Blight. “It is an excellent delivery mechanism because of the normal requirement of fluid intake.” This convenience is coupled with the fact that liquids are amenable to a great variety of flavors.
Whereas everyone consumes liquid, there is a good deal of variability between cultural eating patterns. “If I were to fortify white bread, for example, that wouldn't necessarily provide good penetration into a Hispanic marketplace because they tend to eat more flat bread,” Blight speculates.
Bottom of the BottleA market-viable beverage will have a good flavor system, a sweet taste (but not overpoweringly sweet) and a balanced texture; it also will provide a nutritional benefit.
Taste/flavor was listed as the greatest challenge to product development efforts of respondents who primarily work with beverages in the PF April 2005 survey. “People will try a beverage once and maybe twice, but they won't go back time and again if they don't like the taste of the product,” observes Hemphill.
Delivering a good texture and flavor is just as important as nutritional benefits because the marketplace is unforgiving, says Blight. “Nobody wants a calcium-enriched drink if it tastes like chalk. If it won't stay in solution, then it probably won't be viable in the marketplace.” A consumer is inclined not to buy products with sediment in the bottom of a beverage container.
Fortification Education“One serious challenge with beverage systems that other prepared foods evade is the necessity to keep the additional ingredients solubilized,” says Blight. There are limits of how much solute can be put in a beverage, which determines how much supplementation is possible.
Many of the nutritional additives in beverages are oil-based ingredients that may be insoluble in water. Water-insoluble vitamin additives tend to cloud a beverage and can lead to an off-taste. “Sometimes a 'ring' or 'cream' will form and rise to the surface of the beverage,” says David Olsen, a technical associate at a beverage ingredient supplier. Formulators of clear beverages should look for water-soluble vitamins.
Alternatively, some manufacturers want to keep the natural cloudy appearance in a beverage. During juice extraction and processing, the natural compounds of the juice that cause cloudiness can dissipate. Adding weighting agents to an emulsion can bring back the natural look of cloudiness in a beverage.
“Adding a weighting agent to a vitamin-enriched beverage formulation will increase the specific gravity of the flavored or enriched oil to that of water to help ensure an even dispersion of the vitamins and flavors throughout the beverage,” says Olsen. “Weighting agents, such as sucrose acetate isobutyrate (SAIB), extend product shelflife and ensure the integrity of beverage brands,” he explains.
Some ingredients create a synergistic effect, while others cancel each other out or, at least, reduce how beneficial they are. For example, a substance in grapefruit abstract inhibits the effectiveness of statin drugs. “That is unusual, because it is not uniform to other citrus juice--just grapefruit,” says Blight.
On the flip side, the mineral selenium will increase the antioxidant effectiveness of vitamin E. More than 62% of May's 2005 “Functional Food Survey” beverage respondents said that antioxidant usage would be more important in the coming years. “Antioxidants such as vitamin E and C are becoming very commonplace,” informs Blight. Pomegranate juice has been commercially successful the last couple of years because it is rich in antioxidants.
“RTD Too”Across the board, ready-to-drink is more popular than reconstituted healthful beverages because of convenience. “Powders and frozen, concentrated juices are not growing,” says Hemphill.
Finished beverage products provide an obvious convenience for on-the-go consumers. However, for manufacturers, they create a greater energy demand than powdered drinks, since shipping fully reconstituted beverage products from Miami to Seattle is far more costly, says Blight. Reconstituted powders also appeal to backpackers who do not carry heavy products, and the value-oriented consumer.
A lot of fiber-based beverages are mixed and consumed all at once because it is hard to keep them in solution. Additionally, with powdered formulas, it is easier to super-saturate milk or water with vitamins and minerals since precipitation over extended periods of time is not a concern.
Blight informs that starch companies have made progress by dispersing omega-3 oil in a powder carrier. “In the future, consumers will see things like omega-3 and antioxidants in flavor packets that can have applications as part of fitness-type beverages,” envisions Blight.
The aging population presents another advantage to beverage powders over liquid forms. Due to dysphagia, a disruption in the swallowing reflex, the infirm have a growing demand for beverage thickeners. It is harder for them to initiate a swallowing reflex with low-viscosity beverages. However, manufacturers have a more difficult time keeping ingredients soluble in thickened beverages over a long shelflife. Although such types of drinks are specialty beverages, with an increased aging population, that specialty will become more common.
In the past year, some groups have targeted the beverage industry as an example of companies that enable obesity. “I think the category is doing a good job, but I'm not sure they've done such a good job of telling their story,” notes Hemphill. For example, 7 Up Plus (Plano, Texas), which features real fruit juice, calcium, and vitamin C fortification, displays a positive example of how brands with global market penetration are making adjustments to reach beyond traditional possibilities. Other examples include Coca Cola's (Atlanta) new Diet Coke with sucralose and Anheuser Busch's (St. Louis) 180 Energy X-3, an energy drink with vitamins B6, B12 and C. “Consistently and in almost any category, there are healthful alternatives in beverage segments,” counters Hemphill.
