In sweet goods, such as doughnuts, Carson notes, GemPro Prime-W can contribute a fine cell structure and a softness throughout its shelf life.
“Because wheat protein can support a light, airy texture, it is the ideal protein source for doughnuts, muffins, and snack cakes,” says Carson. “GemPro wheat proteins are 90 percent protein. Our formulations have been able to include wheat protein at up to 20 percent. By selecting the wheat protein with optimal texture attributes, you can reach your protein target while maintaining your product quality goals.”
Wheat protein can also provide a clean-label solution to process efficiency. “GemPro Prime-E is ideal for sheeted applications such as snack pies,” says Carson, noting it can provide extensibility for processing without diminishing the integrity of the dough.
Kevin Binns, global technical lead, sweet bakery, AB Mauri North America, St. Louis, says that when it comes to sweet baked and fried goods, many consumers are willing to accept a higher number of calories, as long as the eating experience is pleasurable. “At the same time, many consumers are seeking health benefits alongside a bit of indulgence. The challenge here is to reduce the fat and sugar content without impacting familiar taste. AB Mauri North America is able to reduce and replace high calorie ingredients like sugar with exclusive stevia-based sweeteners that feature no detriment to product quality.”
Consumers are also reducing frequency of shopping occasions, notes Binns, creating an opportunity to extend product shelf life. “Through the use of baking powders, enzymes, and proteins, AB Mauri North America enhances and extends the freshness characteristics of doughnuts and snack cakes, adding to the eating experience for the consumer.” Vegan options are also available. “As demand for vegan and egg- and dairy-free sweet goods continues to rise, we have found enzyme and plant protein ingredient solutions to meet this need,” he says.
Jill Stang, bakery sales manager, DuPont Nutrition & Biosciences, New Century, KS, says that when considering ingredient options for extending shelf life of sweet goods, and in particular doughnuts, there are three key factors to keep in mind for extending shelf life: softness/moisture control, antimicrobials, and antioxidants. “All three of these key factors are necessary to maintain a quality product that is safe for consumers. If any of the key factors is not present in the finished product, the product quality will diminish quickly, and the product will not be safe through the shelf life.”
“There are three ways of improving a product’s eating quality performance over shelf life: enzymes, emulsifiers, and hydrocolloids. All three have a significant impact on maintaining softness and moisture control,” says Stang. Doughnuts and other sweet goods need softening enzymes designed specifically for those applications, as sugar concentrations in those formulas will inhibit the softening power of certain amylase enzymes, she adds. DuPont Nutrition & Biosciences has found some emulsifiers will enhance the softening effects of the amylase enzymes. This lowers the firming curve while lengthening softness over time. Certain monoglycerides provide this effect, extending shelf life softness without decreasing the resilience of the doughnuts or other sweet goods, she says.
