Abstract
The invention relates to a beer flavor rating method based on an ion selective electrode sensor array, belonging to the field of food intelligent detection. The method specifically comprises steps ofmodeling for a characteristic response signal of a beer ion collected by a sensor array through a signal identification processing system and a mode identification method, and determining a level of the beer flavor by using the model and a relationship between beer ion types and concentration. The beer flavor rating method based on the ion selective electrode sensor array makes beer production more automatic and intelligent, and offers theoretical basis for research of beer flavor detection devices.
Description
technical field [0001] The invention relates to a rapid evaluation method for beer flavor grades, in particular to a rapid evaluation method for beer flavor grades based on ion-selective electrode sensor arrays, and belongs to the field of food intelligent detection. Background technique [0002] Beer flavor is one of the important factors affecting consumers' choice of products. Flavor substances in beer are produced in different stages of beer brewing. The flavors produced during the saccharification process mainly include malt aroma, sour taste, hop aroma, bitter taste, etc., and the reasons for the main influence on beer flavor in this process can be attributed to the following aspects: first, the formed reducing sugars and amino acids undergo Maillard reactions, Then produce a series of flavor compounds, such as the intermediate product glucose ketone aldehyde, dihydropyrrole and so on. When the boiling temperature of wort reached about 100℃, the Maillard reaction spe...
