What is the limitations of proximate analysis?

Proximate analysis primarily provides a basic breakdown of the composition of a sample into components like moisture, ash, protein, fat, and carbohydrates, but it does not offer detailed information about the specific types or qualities of these components. This method can overlook important nutritional aspects, such as the presence of essential vitamins, minerals, and bioactive compounds. Additionally, proximate analysis may not account for variations in digestibility or the functional properties of the nutrients, leading to incomplete assessments of the sample's overall nutritional value.
