Determination of fermentable sugars in the coffee production chain
By determining the amount of total fermentable sugars, glucose, fructose and sucrose, it is possible to assess the correct progress of fermentation. Green coffee beans are rich in fermentable sugars that can be related to quality and organoleptic properties. In roasted coffee fermentable sugars are present only in light roasting.
Analyzing Fermentable Sugars in Coffee: Why It Matters
The analysis of fermentable sugars carried out in the fermentation phase allow to control this delicate process and can be applied to the various types (natural, washed, honey, anaerobic, ...). They have the purpose of determining the right timing of the fermentation process and can give important indications to produce a coffee with the desired characteristics.
The analysis of fermentable sugars carried out on green coffee allow to assess the quality of the product, to evaluate its organoleptic potential and its chemical characteristics. This will allow making the right choices in the following roasting phase and evaluating its conservation over time.
The analysis of fermentable sugars carried out on the roasted coffee are proper to identify the chemical and organoleptic characteristics of the product and to give a first evaluation of the sensory profile that could be found in the cup. The same analysis can also be carried out on the extracted coffee in order to evaluate the efficiency of the extraction process.
Principio del test
The sucrose, fructose and glucose present in the sample are determined enzymatically and therefore are not influenced by the presence of the remaining reducing sugars. The Redox reaction is read at 366 nm (end-point) and the value is directly proportional to the concentration of glucose and fructose in the sample.
