Today’s consumers are demanding “better-for-you” products, and fortified beverages are one way to provide them. Fortification of food products is done, in essence, to satisfy a deficiency. Historic examples are iodine in salt, vitamin C in juices, and vitamins A and D in milk. Beverages favor fortification, because they offer an aqueous phase for dispersion and hydration of concentrated additives. Beverages also are convenient for consumers—often requiring no or little preparation; offering the ability to be consumed on the go; and often viewed as healthful.  

Beverages satisfy an immediate need for consumers starting off the day, as a meal alternative or for body restoration after a physical workout. Frozen beverages, in particular, are often chosen for fortification, as they offer the advantages of (typically) fresher taste and fewer, if any, preservatives or high-temperature processing.

“Also, degradation of additives happens significantly less in a frozen matrix than in a shelf-stable product,” explained Paul Groth, senior R&D manager for Sargento, in a recent Prepared Foods’ R&D Seminar titled “Health and Wellness Additives for Frozen Beverages.” Research currently shows consumers are buying fewer frozen beverages in cans, and more in bag and envelope packages that provide an atmosphere more suited for fortification. (See chart “Frozen Fortification.”)

Groth said options for fortification of frozen beverages include antioxidants, fibers, minerals, proteins, prebiotics, probiotics, phytochemicals and vitamins. Vitamins are required for repair and maintenance of various bodily systems. Fat- and water-soluble vitamins and minerals make good additives; in particular, the B and C vitamins are often added for daily replenishment needs and to help control hunger.

Prebiotics aid in satiety and weight management. They are non-digestible fibers that act as food for the flora already in the gut. Prebiotic fibers are low-calorie and include inulin from chicory root, corn fiber, oat fiber or polydextrins. Probiotic choices include live microorganisms with a variety of functions promoting gut health; strengthening the immune system; and improving brain function. Advantageous probiotic bacteria include Lactobacillus, Bifidobacterium, Bacillus and Saccharomyces. Yogurt and fruit smoothies with probiotics or iced mochas with prebiotics are two examples.   

Proteins and amino acids aid in maintenance of bodily systems and muscle mass. Ingredients beneficial for fortification include whey, soy, casein, leucine, lysine and cysteine. Phytochemicals are substances plants generate during their normal growth and that benefit the host when consumed; they include carotenoids, phytosterols, vitamins and fiber. Antioxidants reduce the effects of free radicals in the body and include vitamins A, C and E, beta carotene, selenium, lycopene, polyphenols, anthocyanins and superfruits. Product ideas include green tea with antioxidants and chocolate shakes with protein. Fibers are cellular materials not digested by humans, and they aid in reduction of blood cholesterol and glucose levels, and promote satiety and regularity. Fibers can be sourced and are available as ingredients from many plants.

Steps for beverage fortification include determination of the base beverage; identification of the intended target market; and selection of additives compatible with the base. Next is to determine the concentration that will allow a product claim, and to determine cost.

Issues for consideration when fortifying are that many ingredients have no standards for claims; not all ingredients have GRAS status; and claims need validation by either analytical or microbiological measurements. pf

—Summary by Elizabeth Pelofske, Contributing Editor


w?�?i?d??Li?X^a?the flavors, parents are firmly the target behind the bars’ nutrition profile: Each bar has 110 calories or less, 8g or less of sugar, 20% of the daily recommended value of fiber and no HFCS.


General Mills has announced its growth plans for fiscal year 2013, and some 70 new product launches in the first half of the year, alone, are at the heart of the agenda. One of its key categories will be snack bars.

“Our future growth plans remain focused on five global categories—ready-to-eat cereal, super-premium ice cream, convenient meals, wholesome snack bars and yogurt,” said Chris O’Leary, executive vice president, chief operating officer, International. “In fiscal 2013, we want to generate growth in our core, developed markets, while expanding our presence in emerging markets worldwide.”

Unsurprisingly, the Kellog Company has similar notions in mind, when it comes to expanding its stalwart brands in the cereal bar segment. Its Special K brand is adding Pastry Crisps. The two varieties—Chocolaty Delight and Brown Sugar Cinnamon—promise 100 calories per serving. At the same time, the company has opted to re-launch Special K protein cereal, “in response to consumers looking for protein for energy and to feel full longer.” In addition, Kellogg plans to add FiberPlus Nutty Delight bars in Peanut & Dark Chocolate and Honey Roasted Almond versions.

Fiber has been at the heart of bars promising to help manage weight, with “high satiety” an increasingly frequent claim on packages. Fullbar, while it does boast 5g of fiber and 5g of protein, is described as a pre-meal bar that will help the consumer feel full and consume less at mealtimes. However, that satiety promise is not exclusively due to the presence of fiber.

Fullbar’s package notes it is “Clinically proven to help lose weight,” and it bears a “Now with All-natural Hunger Block” label. That all-natural hunger blocker is a potato protein extract that promises to minimize feelings of hunger between meals. The active component is Proteinase Inhibitor II, a natural protein found just under the skin of the potato that promises to promote satiety by enhancing “the body’s natural release of cholecystokinin.”

Fullbar is among the many examples of the move toward protein content in helping consumers manage their weight and, in general, improve their overall health. Special K has added a Protein Meal Bar, promising 10g of protein and 5g of fiber, in such varieties as chocolate peanut, chocolatey chip and chocolate delight.

Back to Nature

Under its Nature Valley label, General Mills has added a Protein variety, with each bar providing 10g of protein per bar. Varieties include a peanut butter and dark chocolate option, as well as one that adds almond to that pairing. That Nature Valley brand has drawn criticism and even a lawsuit, however. The Center for Science in the Public Interest (CSPI) filed the suit, accusing the snack maker of “going to great length[s] to market its granola bars and ‘thins’ as ‘natural,’ even though they contain industrially produced artificial ingredients.” The complaint notes high-maltose corn syrup and/or maltodextrin are in dozens of the Nature Valley-branded products. The CSPI notes neither high-maltose corn syrup nor maltodextrin appear in nature and “not even under the most elastic possible definition could they be considered ‘natural.’”

Fiber-enriched satiety, however, is far from the only route to weight control. For that matter, portion control has long been a concern, even for consumers of products that promise to help with managing weight. ThinkThin is one example of a product that has shrunk the bar size, but at the same time capitalized on that fact by noting each bar now has only 100 calories. Its gluten-free bars also boast 6g of protein and 0g of sugar, and are certified-kosher.

While new and innovative sweetening agents have been the means to weight management across a range of other categories, these have been somewhat less prominent in cereal bars. A couple of notable exceptions, however, have incorporated versions of stevia. Access Business Group’s Nutrilite Protein Bars are sweetened with rebiana and promise 21g of protein and 1g of sugar. The Nutrilite line includes such varieties as Chocolate Delight, Cinnamon Bun, Lemon Twist, Blueberry Crunch, Cherry Almond, Cranberry Crunch and Caramel Crème, to name only a few.

Balance Bar Company’s Nimble bar is similarly sweetened with a stevia variety; the bar targets women consumers and promises 120 calories. Balance Bar Co. notes it has maintained a 40-30-30 principle for its range of products, including its recent 100-calorie, mini-energy bars: 40% of calories come from healthy carbohydrates; 30% from quality protein; and 30% from dietary fat. The mini-energy bars, found in cookie dough and double-chocolate brownie varieties, contain 7g of protein and 23 vitamins and minerals, plus serve as an “excellent source” of vitamins A, C and E.

Fiber has clearly become less of a distinguishing factor among cereal bars. For that matter, cereal bar brands have distinguished themselves further by noting their antioxidant content and boasting of inclusions with a healthy aura. Under its Nutri-Grain label, for example, Kellogg has added Superfruit Fusion varieties, with such flavors as strawberry açai promising antioxidant vitamins C and E.  In fact, fiber enrichment would appear to be a cost of entry into the segment and an expectation of consumers. Those consumers are now seeking additional boosts from their cereal bars, be it in the form of added protein, omega-3s, or assorted vitamins and minerals. pf
