The formulations of battered products are a constantly evolving field where the appearance, flavour, and texture are crucial aspects for the product’s success. For this reason, using a predust and/or batter will make a difference in the final result.
What’s the Difference Between Predust and Batter?
Predust is a powdered preparation designed to improve the adhesion of coatings to food and is applied directly to the surface of the substrate. Its composition usually includes flours and/or modified or native starches from cereals such as rice, maize, or wheat, which provide structure and texture to the batter.
The use of pregelatinised flours in the formulation of predust offers advantages and enhances its functionality in batters.
- They improve the adhesion between the substrate and the batter thanks to two factors. First, the predust retains the substrate’s free water, keeping the food juicy and facilitating a stronger bond between the food and the coating. The second factor is that it creates a rough and irregular surface on the food, increasing the contact area between the batter and substrate, improving the coating’s adhesion and preventing it from detaching during cooking or becoming soggy.
- Another main function of predust is that it provides uniformity to foods, preventing areas without coating or with excessive batter.
Now, let’s learn a bit more about batter. Batter is also a powdered preparation, but in this case, it is dispersed in water in variable proportions and is crucial for the preparation of coatings. It creates an intermediate layer that serves as a bond between the substrate (or predust, if used) and the final coating, playing a fundamental role in the adhesion of breadcrumbs and other coatings to the food. Furthermore, it replaces the egg’s binding function and guarantees a crunchy texture and attractive appearance.
Among its main functions are:
- Adhesion: Batter can secure the coating to the substrate, achieving a firm and durable bond.
- It also provides greater internal cohesion to the coating, thus preventing it from disintegrating during cooking.
- Flexibility: Batter provides the necessary flexibility to adapt to different temperatures during cooking, avoiding cracks and breaks in the coating.
- It should be noted that batter can be used as a final layer if you want to create a battered product or alongside breadcrumbs or other coating elements (flakes, crisps, etc.) if you want to create a breaded product.
In Conclusion
Both batter and predust are fundamental ingredients in the production of battered foods. Both play a crucial role in the texture and flavour of these foods. Predust, by improving the adhesion of the substrate, and batter, by creating a more uniform, tasty coating with characteristic texture, contribute to the creation of battered products that meet the expectations of the most demanding palates.
