Second-generation replacement of trans fats and the removal of glutens continue to dominate product development activity in the baked goods category of the food industry.
While there are “only” an estimated 2 million people in the U.S. with celiac disease, there are millions more who are either undiagnosed or who have diet sensitivities that are leading them to avoid glutens. And their numbers are growing as there is evidence, though far from convincing, that gluten may be connected to such wide-ranging maladies as autism, multiple sclerosis and attention deficit disorder.
If you watch TV’s “The View,” you’ve heard Elisabeth Hasselbeck, one of the co-hosts, talk about how removing wheat from her diet ended years of intestinal agony. She even wrote a book: “The G-Free Diet: A Gluten Survival Guide.”
There have been gluten-free products for a decade or more, but most came from small bakers. In the past year or so, however, the big guys have joined the fray.
Just before the end of last year, General Mills launched a web site, www.liveglutenfreely.com, to highlight its gluten-free products and to provide consumers with gluten-free recipes and information on how to buy and live without the problematic protein.
“One of the most frequent inquiries our customer service department receives is ‘What products are gluten-free?’ ” says Katie Lay, marketing manager of General Mills’ Health and Wellness division. “Consumers should always consult product labels prior to purchase, but our new website can give them 24/7 access to information about General Mills’ gluten-free products. We also created an electronic newsletter by the same name that consumers can subscribe to. Gluten-free product information and gluten-free recipes will be sent directly to their inboxes.”
Prior to launching www.liveglutenfreely.com, General Mills created a line of Betty Crocker gluten-free dessert mixes. The company’s Yoplait yogurt, Larabar fruit and nut bar, Betty Crocker Fruit Snack and Chex cereal product lines all contain several gluten-free items.
While General Mills is not alone, none of the biggest food processors is so heavily promoting or developing such products. The words “gluten” and “gluten-free” turned up zero hits on the web sites of all the other top 10 U.S. food companies (admittedly, many don’t have any products containing glutens). Zilch for Kellogg Co., despite its baked-goods portfolio. Nestle USA points out “almost all the Wonka candies are gluten free except for Oompas and the Wonka Bar,” and Libby’s 100% Pure Pumpkin is naturally gluten- free (and there’s a recipe for making a gluten-free pumpkin pie). Kraft has a Balance Fruit & Nut Energy Bar that’s gluten-free.
ConAgra Mills’ Eagle Mills All-Purpose Multigrain flour is a natural, whole-grain blend of the company’s “Ancient Grains flours” — amaranth, millet, quinoa, sorghum and teff — as well as brown rice and tapioca starch. The gluten-free flour contains five of the six grains dubbed the “super six” by Melinda Dennis, nutrition coordinator at the Beth Israel Deaconess Medical Center Celiac Center, for their high vitamin and fiber content. The proprietary blend was formulated to achieve optimal texture, flavor, appearance and functionality in a variety of grain-based foods.
Ingredient suppliers are helping out with the gluten-free trend. Gum Technology Corp. (www.gumtech.com), Tucson, Ariz., recently discovered new uses in baked goods for its Coyote Brand Stabilizer ST-101, a blend of xanthan gum and guar gum.
Gluten mixed with water will produce an elastic and porous web, which is capable of trapping the gas bubbles that leavening agents produce allowing the product to rise. Stabilizer ST-101 is a natural gum blend that can replace that functionality in baked goods.
Gum Technology has found other bakery uses for ST-101. It binds moisture (reducing staling), improves cell structure, increases dough pliability and improves freeze/thaw stability. “It works well in everything from soups to baked goods,” says Sarah Martin, Gum Technology’s R&D chef. “It’s a blend that seems to have been around forever but we keep finding new ways to use it.”
Dow Wolff Cellulosics’ (www.dowwolffcellulosics.com) Methocel gluten replacer is a cellulose-based fiber providing moistness throughout the shelf-life of baked goods, preventing collapse during baking and avoiding the gas or bloating effects associated with many other sources of fiber.
Market research firm Datamonitor has recorded a steady increase in the past decade in the number of new products with a gluten-free claim: from 0.7 percent in 2000 to 10.4 percent last year.
“Gluten free has had a huge run-up since around 2005 -- the numbers have doubled since that time period,” says Tom Vierhile, director of Datamonitor’s Product Launch Analytics. “And the growth from 2008 to 2009 is also impressive since gluten-free should have been showing signs of age at that time. You would not know it from the numbers.”
The top categories, in order, for gluten free food products in 2009, based on the number of new product reports making that claim were:
- Other Savory Snacks (snack mix, puffed snacks, some fruit snacks, trail mix and more)
- Cereal Bars
- Potato Chips
- Wet Cooking Sauces
- Sugar Confectionery
- Bread and Rolls
- Baby Snacks
Still removing trans fats
Ken Hays of Bunge Oils tests shortening for performance in laminated dough. Ken specializes in reformulating for trans fat-free customer solutions.
Marvin Goertz of Bunge Oils works with a piece of pilot plant equipment to check shortening work softening characteristics for Bunge Oils' trans fat free customer solutions.
Four years after the FDA began requiring the declaration of trans fats, some processors still are in search of the perfect replacement for their formulations.
“Most of the companies were ready with reformulations [by the January 2006 deadline] but many had not found the optimal replacement,” says Gary List, a retired USDA regional official specializing in fats and oils, and now a consultant to the food industry – including to the United Soybean Board.
“The baking industry, in particular, requires solid fat for many applications. It provides structure, incorporates air, builds up layers.” Saturated fats were not an option, so bakers first turned to interesterified fats, most of which were higher in saturated fats than trans fat but at least they had no trans fats.”
“There seem to be three approaches bakers and their fats and oils suppliers are taking: conventional processing that minimizes hydrogenation, use of palm and palm kernel oil fractions or enzymatic interesterification,” which rearranges two oil streams to get the best characteristics of both, says Roger Daniels, director of R&D in the Bradley, Ill., Oil Center of Excellence of St. Louis-based Bunge Oils (www.bungeoils.com).
All have their places, he says, as each application must find the balance among taste, quality, convenience and price. Another four-way balance he notes is finding the best oil or fat “for the factory, for the distribution system, for shelf life and for the consumer.”
Caravan Ingredients (www.caravaningredients.com) developed Trancendim, a line of primarily diglycerides for bakers. “It’s a beta prime crystal modifier, so it can be used to structure any oil you start with,” says Larry Skogerson, vice president of R&D at the Lenaxa, Kan., company.
You can start with any oil that best fits your formulation and desired end result and label declarations, he says, and Trancendim makes it act like a plastic shortening. “You get no more trans fat than was in the oil you started with; your label declaration can say monodiglycerides and oil; and it often can reduce the overall fat content 20-50 percent because of the structuring you get,” he says.
There are several different formulations of Trancendim depending upon the desired ratios of mono-, di- and triglycerides.
Besides trans fats, sodium is another growing formulation concern, even in baked goods. By developing leavening alternatives to sodium acid pyrophosphate, ICL Performance Products (www.icl-perfproductslp.com), St. Louis, helps bakers reduce sodium and add calcium, possibly enough calcium to make a calcium label claim.
ICL’s Levona family of leavening agents are calcium pyrophosphates, providing the same functionalities as sodium acid pyrophosphates. Levona Opus provides a slow and delayed leavening action, suitable for frozen and refrigerated products. Levona Brio is a faster grade of leavening acid, delivering carbon dioxide early in the baking process.
