Difference between proximate analysis and weende analysis?
Proximate analysis determines the basic chemical composition of a feed sample, focusing on moisture, crude protein, fat, fiber, and ash content. Weende analysis is a specific method of proximate analysis that focuses on determining the crude protein, fat, fiber, and nitrogen-free extract content of feed samples. In summary, while proximate analysis is a broader term, Weende analysis is a specific method within proximate analysis that focuses on certain components.
What is the Proximate analysis importance?
Proximate analysis is important because it provides information on the major components of a sample such as moisture, ash, volatile matter, and fixed carbon. This analysis helps in assessing the quality and energy content of a material, which is crucial in various industries like food, fuel, and agriculture. By understanding the proximate composition, producers can make informed decisions about processing, handling, and utilization of materials.
How do you convert proximate analysis of coal to ultimate analysis?
To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
What is the difference between proximate and ultimate analysis?
Proximate analysis determines the moisture, ash, volatile matter, and fixed carbon content of a substance, while ultimate analysis determines the elemental composition (carbon, hydrogen, nitrogen, sulfur, oxygen) of a substance. Proximate analysis provides information on the physical and chemical properties, while ultimate analysis provides information on the elemental composition.
Why is the proximate analysis of carbohydrate (nitrogen free extract) determined by difference instead of direct analysis?
Proximate analysis determines the major components of a food sample such as moisture, protein, fat, and ash. Carbohydrate content (nitrogen free extract) is calculated by difference because it encompasses all non-protein, non-fat, and non-ash components. This indirect approach accounts for any discrepancies or impurities in the sample, providing a more accurate estimation of the carbohydrate content.

What is proximate analysis of protein?
proximate analysis of fat can be done by using soxhlet apparatus
What is the Proximate analysis importance?

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.
Importance of proximate analysis?
Proximate analysis is important because it is one of the most effective ways to analyze nutritional value and energy value in food.
Why you do proximate analysis?
We do proximate analysis of the matter to know the nitrogen (protein), oil (fat), mineral, ash content etc to have an idea about the energy contained in that matter.
How do you convert proximate analysis of coal to ultimate analysis?
To convert proximate analysis of coal to ultimate analysis, use the Dulong formula as follows: Carbon = 0.75*(fixed carbon + [volatile matter/100]); Hydrogen = 0.06volatile matter; Oxygen = [moisture/100] + 0.3sulfur - carbon - hydrogen; Nitrogen = volatile matter/100 * 0.01. This formula estimates the ultimate analysis (C, H, O, N) from the proximate analysis (moisture, volatile matter, fixed carbon, ash).
Why is vitamins not included in proximate analysis?
because the proximate is just to find the crude one only and they are denatured by heat.
What is proximate analyzes of food?
in proximate analysis of food, you determine for moisture content in the food, you determine for ashing, you determine for protein, crude fiber and so on

What are the limitations of the proximate analysis of feeds?
The uses of heat result in escape of some volatile components
