What are the limitation of proximate analysis?

Proximate analysis provides a basic breakdown of the composition of food or feed, typically measuring moisture, ash, crude protein, crude fat, and fiber. However, it does not account for the nutritional value of different components or the bioavailability of nutrients, potentially leading to an incomplete understanding of the material's overall quality. Additionally, proximate analysis can overlook specific compounds such as vitamins, minerals, and phytochemicals, which are crucial for assessing health benefits. Finally, variations in sample preparation and analytical techniques can affect the reproducibility and accuracy of results.
