You will need to submit a sample (100g or more) of your dog, cat or pet food product to our lab for pet food nutrition analysis. AAFCO (the Association of American Feed Control Officials) is equivalent to the FDA for pet food testing and is a top organization that oversees pet food standards. For more information about AAFCO, click here. Pet .
Protein analysis – Determining nitrogen content using Kjeldahl. Foods tend to contain a lot of different proteins. It is virtually impossible to analyze how much there is of each protein, nor does it provide a lot of added value. That’s why most labels only require the overall protein content. It is used in labs to detect the presence of peptides or proteins in a sample. It is a qualitative test, and can only state the presence or absence of the peptide bonds but demonstrate nothing about the exact quantity and type of proteins. . Used in food analysis to detect the addition of proteinaceous adulterants in non-protein products . The fat content in food has always been a widely discussed and scrutinized element of nutrition for both consumers and food industry professionals. Many shoppers are interested in the amount of fat in food for a variety of reasons—health, nutrition, weight loss, type 2 diabetes, and more—and want to know the precise amount before making nutritional decisions.In 1883, Johan Kjeldahl introduced his "New Method for the Determination of Nitrogen in Organic Bodies", revolutionising nitrogen analysis and setting new standards. Since then, the method has become indispensable in areas such as food analysis, feed analysis, soil analysis and water analysis.However, it is by no means limited to these areas: This versatile method can also be .

Eurofins is Testing for Life. Eurofins is the global leader in food, environment, and pharmaceutical product testing. Established in 1987, Eurofins started with one laboratory, ten employees, and one method. Today, Eurofins has ca. 62,000 staff in 62 countries and operates over 900 laboratories.Comparing Wet and Dry Pet Food. The Guaranteed Analysis can also help consumer compare levels of nutrients in different pet foods. To make a meaningful comparison between a nutrient level in two foods, it’s important to evaluate the nutrient levels in the absence of the moisture content, in other words, on a “dry matter basis,” particularly when comparing wet and dry foods.
The procedure for the Biuret Test for Protein is straightforward, and the results are easy to interpret. Overall, the Biuret Test for Protein is an essential tool for protein analysis in research and diagnostic laboratories. .AAFCO Compliant Pet Food Testing and Guaranteed Analysis completed in a Certified Laboratory.

Food manufacturers and government laboratories routinely analyze food products to ensure that they do not contain harmful substances and that the food production facility is operating correctly. 1.1.3. Quality control . The food industry is highly competitive and food manufacturers are continually trying to increase their market-share and profits.
Nutritional analysis is the process of determining the nutritional content of food. It is a vital part of analytical chemistry. . For this approach, food companies send samples of food to laboratories for physical analysis. By utilizing scientific methods and equipment the food sample is analyzed for the different components that compose the .For this experiment, each group will need to bring to the lab a suitable sample for protein analysis. The most convenient samples are animal or plant food products that have significant protein content and are available in liquid or powder form. For example, you can use a liquid protein product such as Ensure orused in protein laboratories. Variance Expected In Protein Result . Discussion of protein variance will be con fined mostly to the basic Kjeldahl procedure, be cause almost all protein laboratories are still using this method. Protein for samples in the grain trade are obtained from a single analysis on each sam ple.Choosing a laboratory “A List of Analytical Laboratories Serving Oregon (EM 8677)” contains contact information for labs that analyze forage samples. Prices and sample submission guidelines may differ among laboratories. Call the lab prior to taking the sample. Lab fees start around per sample and increase depending on the analyses .
The expected caloric content in food is associated with carbohydrates, fat and protein. The Food and Drug Administration (FDA) has regulated the reporting of such macronutrients (carbohydrates, fats, protein) on food items in the United States. The label is referred to as the Nutrition Facts label on food packaging. This label provides the size . Just as the genome is analyzed using the basic technique of DNA sequencing, proteomics requires techniques for protein analysis. The basic technique for protein analysis, analogous to DNA sequencing, is mass spectrometry. Figure \(\PageIndex{1}\): Mass Spectrometer: Matrix-Assisted Laser Desorbtion Ionisation – Time Of Flight (MALDI-TOF) .The accurate and precise determination of protein not only plays a role in the characterization of nutritional or dietary value in food materials, but is also the key to the economic value of these materials. Protein is most commonly calculated using the measured nitrogen content in a sample, and a multiplier or conversion factor. Food production companies need to monitor protein content at multiple points along the food process chain. The three most common techniques used to measure protein content are Kjeldahl, Dumas (combustion), and NIR (near-infrared spectroscopy). While all three are valid, each of these methods comes with unique advantages or challenges.
