Fat and oil content is an important measurement of nutritional value and product quality for many foodstuffs. In particular, this value is widely used to determine energy content and to calculate the proportion of other components in foods (e.g. carbohydrates). In addition, the fat and oil content may significantly affect the texture, perceived quality and flavour of products. Thus, accurate measurements of the fat and oil content enable the manufacturers to achieve higher standards in nutritional characterisation and quality control of foodstuffs.
