| titleOfInvention | A kind of determination method of pear paste concentration end point |
| abstract | The invention discloses a method for judging the concentration end point of pear paste, comprising the following steps: (1) measuring a pear paste sample with known total phenolic content, total acid content and color difference by using a fluorescence photometer to obtain three-dimensional fluorescence spectrum data; using a parallel factor method Analyze the three-dimensional fluorescence spectrum data, establish a 2-factor model, and combine the characteristic factor 2 intensity with the regression equation established by the total phenol, total acid, and color difference in the pear paste sample; (2) use a fluorescence photometer to measure the pear paste sample to be tested, and obtain the test pear paste sample to be tested. Three-dimensional fluorescence spectrum data of the pear paste sample; predict the total phenol, total acid and color difference in the pear paste sample to be tested according to the regression equation, and determine the concentration end point of the pear paste. The method for judging the concentrated end point of pear paste provided by the invention has the characteristics of accuracy, rapidity, strong operability, high stability and good product quality, and the product quality conforms to the industry group standard. |
