Description générale

Free Amino Nitrogen (FAN) is the main source of nitrogen necessary for yeast growth and proper fermentation. Fermentation of beer and wine is processed by yeast, which synthesize proteins using available amino acids. When making beer and wine, free amino nitrogen is extracted from amino acids during the formation of the wort or must.

Application

The Free Amino Nitrogen Assay Kit may be used for:
  • Alcohol Fermentation Analysis
  • Food and Beverage Analysis
  • Yeast Proliferation Analysis

Caractéristiques et avantages

  • Efficient and Precise: Utilizes just 5 μL of sample while detecting a wide range of 0.2 to 10 mM free amino nitrogen, providing sensitivity and accuracy.
  • Streamlined Procedure: Experience a straightforward process with the addition of a single working reagent and a quick 10-minute assay reaction, minimizing time and effort required.
  • Compatibility with High-Throughput Systems: Easily integrate our kit into high-throughput handling systems, guaranteeing efficiency and precision in your laboratory operations.

Adéquation

The kit is suitable for Free Amino Nitrogen determination in foods and beverages (e.g. beer, wort, wine, must, etc.).

Principe

The Free Amino Nitrogen Assay Kit measures alpha amino acids, ammonia, and end group amino nitrogens. The ninhydrin based reaction is a superior method for determining only alpha amino acids and ammonia compared to the traditional Kjeldahl, which measures nitrogen from all sources. The stable ninhydrin reagent provides a simple and accurate method for determining Free Amino Nitrogen concentrations.
