In an increasingly competitive environment, margins are always under pressure. Profitability is greatly enhanced by even marginal improvement of flour yields, resulting in a competitive advantage. The target is to achieve maximum flour yield with acceptable flour ash and quality, without compromising the production rate. However, higher flour yield is often associated with an increased ash content in flour, making it inferior for wafer production. In this case Sternzym LQ 15080 is the best option to ensure a consistent product quality, even with poorer flour qualities, enabling a continuous and trouble-free production.
High extraction flour contains more material from the bran layers, including a high amount of non-starch polysaccharides (NSP) such as pentosans. This causes a drastic increase in the wafer batter viscosity, making it difficult to process.
For instance, using a flour with 0.79 % ash results in a very high batter viscosity, making it barely workable on the wafer machine. The result is an incomplete wafer sheet, even when using Sternzym LQ 4020 (see Fig. 1).
For processing high extraction flour, Sternzym LQ 15080 is best suited due to its strong cellulase and hemicellulose activity. Thus, this enzyme system efficiently hydrolysis NSP and hence mitigates viscosity related production problems. The distinctly reduced viscosity enables the production of high-quality wafer sheets (see Fig. 2).
