For many bakery applications, creating an entirely plant-based, vegan-friendly formulation is complicated by the challenge of replacing eggs—which provide structure, emulsification, flavor and texture.
Substituting eggs with plant-based ingredients has been an ongoing challenge in many categories of bakery products and has implications from processing to final product attributes. Fortunately, innovations in plant protein ingredients have revolutionized formulators’ abilities.
One useful new ingredient for the formulator’s toolbox is derived from canola, and it is poised to gain traction for its functional benefits, including its ability to replicate the functionality of eggs. The specific proteins uniquely abundant in canola are what make it such a suitable replacement.
Primarily grown as an oilseed crop, canola features 90% protein content, boosting the nutritive profile of plant-based applications. Each of the two major proteins found in canola, cruciferin and napin, have very distinctive functionalities, and each can emulate some of the functionalities of yolks and whites in eggs. Isolating these proteins has proven to be an effective egg replacement in a diverse range of food and beverage applications.
Eggs serve many purposes in batter-based products, including nucleation or aeration, binding and gelation; they influence texture, flavor, color and aroma. In products like cakes and muffins, achieving a uniform crumb structure is difficult without eggs, due to their ability to properly aerate the batter prior to baking. This in turn affects the crumb and texture of many applications. Napin, the albumin found in canola protein, shares egg albumen’s unique ability to whip and incorporate a large amount of air into food formulations. And when combined with the gelation functionality of cruciferin, it can set into a stable crumb. Canola protein can be used to replace whole fresh or dried egg whites in batter mixes to achieve a truly plant-based product, without sacrificing taste and texture.
Applications: Cakes, brownies, pancakes, muffins
