摘要
The flavor and texture effects of soy protein fortification of low-fat dairy-based ice cream were characterized. Low-fat ice cream mixes were formulated with 0%, 2%, and 4% soy protein isolate (SPI). Sensory attributed, volatile flavor components, instrumental color, and viscosity were compared. SPI-fortified mixes displayed different textural and color properties compared with the 0% SPI control. Green/grassy and doughy/fatty flavors increased in intensity with added SPI. Instrumental volatile analysis revealed higher intensities of hexanal, (Z)-4-heptanal, 2-acetyl-1-pyrroline, and (E,E)-2-4-decadienal in the SPI-fortified mixes compared with controls. This information will aid in the design and optimization of an acceptable soy-fortified dairy ice cream.
