产品说明
一般描述
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.
特点和优势
- Linear detection range (5 μL sample): 0.2 to 10 mM for 10 min reaction.
- Compatible with high-throughput handling systems.
适用性
The kit is suitable for Free Amino Nitrogen determination in foods and beverages (e.g. beer, wort, wine, must, etc.).
原理
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.
