Features of Texture in Food Volume 2: Solid Food:
- Summarizes research on what influences texture
- Provides practical strategies for improving product quality
- Reviews ways of controlling the texture of fruits and vegetables
Part 1 book reviews research on understanding how consumers experience texture when they eat, and how they perceive and describe key textural qualities such as crispness.
Part 2 considers the instrumental techniques used for analysing texture. It includes chapters on force/deformation and sound input techniques, near infrared spectroscopy (NIR), nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI).
The final part examines how the texture of particular foods may be better understood and improved. A number of chapters review ways of controlling the texture of fruits and vegetables, including the role of plant structure and compounds, the handling of raw materials and technologies such as freezing and vacuum infusion. A final group of chapters discuss the texture of cereal foods, including bread, rice, pasta and fried food.
