Measuring Physical Properties of Foods

摘要

All these questions address the physical properties of foods. Such straightforward questions, however, can be deceptive. The common-sense ideas of how a particular object looks and feels are actually very difficult to determine in an exact way. Sayingan apple is red, round, and hard leaves a lot to be desired especially if quality standards and specifications need to be applied. Unfortunately for food technologists, the physical attribute questions are the ones that most often need to be answered. Food technologists are interested in physical properties in order to determine how foods will handle during processing, get an indication of the product's quality, and understand why consumers prefer certain foods. They approach the problem of physical property measurement in two ways: sensory and objective evaluation.
