What is the importance of ash content in food substances?

Ash content in food substances is important as it indicates the total mineral content present in the food, which includes essential nutrients like calcium, potassium, and magnesium. It provides insight into the nutritional quality of the food and can help assess its dietary value. Additionally, measuring ash content can be crucial for food labeling, quality control, and ensuring compliance with food safety regulations. High ash content can also affect the taste, texture, and overall quality of food products.
