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.

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 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.
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 proximate composition?
Proximate composition is the six categories (based on chemical properties) of compounds (macronutrients) in feed quantified by the Weende or proximate analysis that was developed in 1860 by Hennberg and Stohmann in Germany. This include; moisture, ash, crude protein, crude lipid, crude fibre, and nitrogen free extract (digestible carbohydrate). - Anyalogbu, Ernest Anayochukwu. FUTO, Nigeria.
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.

What is proximate analysis of protein?
proximate analysis of fat can be done by using soxhlet apparatus
Nutrition Analysis?
Nutrition analysis became an essential part of most food labels after enactment of the Fair Packaging and Labeling Act. In 1994 the nutrient content label was changed to Nutrition Facts. Nutrition analysis determines the quantity and type of nutrients in a food. A food's nutrient content is analyzed by proximate analysis. Proximate or chemical analysis measures carbohydrate, fat, and protein content of a known quantity of food. Results are entered in a nutrient database which is used to generate Nutrition Facts labels. Professional organizations such as the Association of Official Analytic Chemists (AOAC) publish official methods of proximate analysis.
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

Literature review on proximate analysis on clarias gariepinus fish?
A literature review on the proximate analysis of Clarias gariepinus, commonly known as the African catfish, reveals significant insights into its nutritional composition. Studies typically indicate that this species has a high protein content, ranging from 15% to 20%, along with essential fats and a low carbohydrate profile. Variations in proximate composition can occur based on factors such as diet, habitat, and age. Understanding the proximate composition is crucial for optimizing feed formulations and enhancing aquaculture practices for this economically important fish.
In proximate analysis pyrogallol is used for analysis of which element?
its answer is oxygen because pyrogallol absorbs oxygen so used to measure amount of oxygen in any substance
