Compositional analysis of food

Compositional Analysis in Food

The compositional analysis of food provides detailed information about food components such as protein, vitamins, fat, fibers and minerals that are used to comply with regulatory purposes and to provide with an answer to quality control needs throughout the entire food supply chain. There are a number of methods and technologies that can be used to perform compositional analysis. The choice of the appropriate solution depends on the type of food matrix, the analysis to perform and the method validation. With its broad range of technologies, PerkinElmer is now able to provide fast, accurate and precise solutions for the compositional analysis of food and foodstuff at every stage of the process. We offer the broadest IR and NIR portfolio in the market, with dedicated analyzers for specific applications like grain and dairy, as well as general purpose instruments suitable for a wide range of users, both for lab-based analysis as well as on-line process measurements.

Nutritional Analysis

For accurate analysis of the nutritional content in food products and compliance with labeling regulations, food producers around the world turn to analytical solutions from PerkinElmer.

Both organic components (such as protein) and inorganic components (such as iron and calcium) can be rapidly measured with our instrumentation. The extended dynamic range capabilities of our category-leading inductively coupled plasma mass spectrometers (ICP-MS) — providing nine orders of magnitude — are ideal for measuring macro-level nutritional elements such as Mg, K, and Na.

Our instruments help food companies ensure that ingredients meet Certificate of Analysis (COA) specifications, guaranteeing proper consistency and nutritional levels. They also support the confirmation of food label claims, making sure that the nutritional content in the food matches what is stated on the product label. Applications span a wide range from infant formula to highly-processed food products.

With precision measurement capability and rapid turnaround speeds, our analytical solutions are the preferred option for obtaining the nutritional information required in the food industry.

Proximate Testing

The determination of major components in food such as moisture, protein, fat, fiber, carbohydrate, ash and other minor components, has a relevant role for Quality Control, product development and regulatory compliance. For this reason, fast analysis times are crucial. We can help you to optimize your proximate analysis through a range of dedicated, reliable and proven solutions.

Metals, Minerals Testing

Originally performed by manufacturers to ensure product quality and safety, the analysis of metals in food is now required by most of the regulatory agencies and to determine compliance with current trade and food labeling laws. The analysis of metals and minerals in foods is challenging due to the wide range of concentrations present, which may vary from ppb (ng/mL) to percent levels. The situation is further complicated by naturally occurring seasonal and varietal differences. As a global leader in atomic spectroscopy solutions, PerkinElmer supports food laboratories to meet the most demanding requirements for the elemental determination of metals in food.

Sugar Testing

The growing awareness and attention of consumers along with the continuously evolving of nutrition labeling requirements have made sugar and carbohydrates analysis a need in the Food and Beverage industry. The analysis of the sugar content, additionally, can provide information about possible adulteration. With a portfolio of analytical technique ranging from NIR analyzers, to LC- and UV- based instrumentation, PerkinElmer is able to provide solutions for sucrose determination as well as for glucose and other carbohydrates.

Fatty Acids, Vitamins & Aminoacids

Fatty acid profiling is a critical analysis for the Food industry. It can be used for example for the determination of the quality of oil seeds. For seed breeders, the fatty acid profile is also critical as there is an increasing demand for varieties with specific characteristics. Our Diode Array NIR analyzers can determine individual fatty acids with accuracy in only 6 seconds. Through our GC-FID technique is possible to determine the relative abundance of fatty acids in oil after triglyceride hydrolysis and subsequent saponification in basic medium (to obtain the corresponding methyl esters). For instance, the presence of fatty acids normally absent in the olive is indicative of adulteration of the product with oils obtained from different seeds.
