Influence of physicochemical characteristics of flour on pancake quality attributes

This study was conducted to identify the influence of flour characteristics of 13 Korean wheat cultivars on quality attributes of pancake. Pancake diameter showed negative correlation with SRC with distilled water and pancake height and positive correlation with springiness of cooked pancake. Springiness of baked pancake was under negative correlation with protein content, SDSS, dry gluten content, and positive correlation with final viscosity and setback in pasting properties of flour. Springiness and cohesiveness of baked pancake were under negative correlation with mixing time of Mixograph. Hardness of baked pancake was correlated with amylose content and breakdown of flour. Regression and principal component analysis indicated that pancake diameter, and springiness and cohesiveness of baked pancake can be explained by protein quantity and quality parameters, protein content, SDSS, mixing time of Mixograph, and SRCs related to protein content. Hardness of baked pancake can be predicted from amylose content and breakdown of flour. Batter viscosity as well as texture of cooked pancake could be influenced by protein quality and quantity according to grain hardness.

Effect of wheat flour characteristics on sponge cake quality

BACKGROUND

To select the flour parameters that relate strongly to cake-making performance, in this study the relationship between sponge cake quality, solvent retention capacity (SRC) profile and flour physicochemical characteristics was investigated using 38 soft wheat samples of different origins. Particle size average, protein, damaged starch, water-soluble pentosans, total pentosans, SRC and pasting properties were analysed. Sponge cake volume and crumb texture were measured to evaluate cake quality. Cluster analysis was applied to assess differences in flour quality parameters among wheat lines based on the SRC profile.

RESULTS

Cluster 1 showed significantly higher sponge cake volume and crumb softness, finer particle size and lower SRC sucrose, SRC carbonate, SRC water, damaged starch and protein content. Particle size, damaged starch, protein, thickening capacity and SRC parameters correlated negatively with sponge cake volume, while total pentosans and pasting temperature showed the opposite effect.

CONCLUSION

The negative correlations between cake volume and SRC parameters along with the cluster analysis results indicated that flours with smaller particle size, lower absorption capacity and higher pasting temperature had better cake-making performance. Some simple analyses, such as SRC, particle size distribution and pasting properties, may help to choose flours suitable for cake making.
