Research on batters is tending towards the creation of highly complex systems that incorporate combinations of increasingly sophisticated ingredients, developed for their multi-functionality. The incorporation of dietary fibres that absorb less fat, starches that develop crisp textures and are less susceptible to human digestion, celluloses that eliminate the pre-frying step and also absorb less fat in final frying, or minor ingredients with antioxidant properties that extend the shelf life of the final product, is already a reality. The dramatic increase in the development of new ingredients brings with it a need for research to clarify their mechanisms of action and the interactions between their functionalities. There is a need to apply improved methods for the control of raw batters, such as the current techniques of dynamic rheology and microscopy, which are used to characterize complex rheological behaviour associated in many cases with the development of three-dimensional structures that condition the entire performance of the coating.
On the other hand, no satisfactory answer has yet been found for such a simple question as “What is the best wheat flour that can be chosen to develop a wheat flour-based batter?” This is an indicator of the need for research in an area that has been based on empiricism for many decades.
Frozen, coagulated products that are fat-free or have the lowest possible fat content, microwave able products or products that can be cooked in an conventional oven, products that incorporate improved characteristics of crispness and juiciness, and products that maintain these characteristics during long holding times are some of the focuses of attention towards which research needs to be directed.
