Review Date: 20 Jan 2020 | BUCHI
The Proximate NIR Analyzer offers reliable results with minimal effort thanks to innovative features such as ready-to-use pre-calibrations, waterproof and stainless steel housing, exceptionally hygienic design, intuitive touch-screen control and the unique Autocal function. The instrument can be easily operated by any user regardless of their skill level.
The application-focused design of proximate makes the system ideally suited for NIR analysis in the following segments:
- - Dairy - Products such as Yogurt, Cheese, Butter and Milk Powders
- - Meat - For example, Beef, Pork, Chicken, Fish and Sausage
- - Grain - whole grain cereals including wheat, barley and maize (corn), as well as ground cereals, wheat flour and semolina.
- - Feed - Mixed and finished feed including ruminant, swine, poultry plus concentrate, as well as plus ingredients such as oil seed meals, cereals and hulls & bran
Typical parameters analysed by the instrument include :
Moisture, Dry Matter, Fat, Protein, Lactose, Ash, Starch, Gluten. Peroxide value, Free fatty acids (FFA) Fibre, Ash and Connective Tissue.
Streamline food analysis: Using reference methods for NIR calibration
Food manufacturers must meet stringent regulatory and legal declaration requirements to remain competitive and ensure regulatory compliance. Proximate analysis has become the contemporary method for quantifying macronutrients in food and pet food, while also providing referenced methods for effective calibration of near-infrared (NIR) spectroscopy techniques, which can streamline workflows considerably and reduce costs.
In this free expert guide, explore a variety of technology solutions for the effective analysis of macronutrients to ensure that food and pet food products remain compliant.

Cannabinoid screening and determination in cannabis processing with NIR
This application note by Buchi describes a convenient, fast, robust, cost-effective, and environmentally friendly analytical method to provide quantitative data of THC and CBD content in different sources of cannabis.
Guidebook to proximate analysis
A method for the quantitative analysis of the different macronutrients in food stuff is called proximate analysis. Nutritional analysis began in 1861 and since then it has have been continuously developed, modified and improved. The analysis uses combination of techniques to determine protein, fat, moisture, ash and carbohydrates that are well documented due to the need for legal declaration requirements.
