Lipid composition and the physical and sensory characteristics of strawberry biscuit fillings

Abstract

The fillings of five Brazilian brands of sandwich cookies were evaluated for their lipid content, fatty acid composition, water activity, average diameter and particle size distribution, morphological appearance, texture (firmness and adhesiveness) and sensory acceptance for the attributes of: overall flavour, strawberry flavour, colour, grittiness, waxiness and firmness. The five commercial fillings showed values ​​for water activity of from 0.47 to 0.50. Only one sample differed in particle size, presenting a larger mean diameter and lower acceptance due to grittiness. There was greater variation in firmness between the commercial brands (from 37.41 to 124.04 gf) as well as in the fatty acid composition, indicating that the fats used in the fillings came from different lipid sources. The average lipid content was 27.5%, which was close to the value found in the literature of 30%. With respect to the fatty acid composition, the average value for trans fatty acids indicated that the industries were really reducing the levels of these fatty acids, but the amounts of saturated fatty acids were still high.
