Consumer acceptance of fatty spreads

Abstract

The effect of consumer trends on the purchase of reduced fat products in general and fatty spreads in particular are discussed. A variety of fatty spreads with fat levels ranging from 20 to 80% were assessed by cone penetration measurements and sensory assessments. The results indicated that butter had poor spreadability characteristics at 5° and 10°, while mechanically worked butter (spreadeasy butter) gave a significantly different texture profile, as measured by the Instron Model 1000. This butter type was assessed as being spreadable at 10° by the sensory panelists and by cone penetrometry. Comparable values of hardness were obtained using data obtained by cone penetrometry and texture profile analysis from the Instron. Low fat spreads (fat levels 25–39%) produced desirable spreadability characteristics using both objective and subjective methods of assessment. Sunflower oil‐based spreads and very low fat spreads, i.e. ≦ 25% fat, were assessed as being soft and oily. The results overall indicated that the use of a cone penetrometer and the subsequent calculation of a yield value gave, using Haighton's seven‐point scale, a good indication of spreadability characteristics.
