Abstract

The invention discloses a rapid detection method for ligustrazine in balsamic salad dressing at eight degrees. Rapid detection is conducted through an electronic nose, and the method includes the steps of standard curve preparation and sample testing. The method is simple in operation process, samples do not need preprocessing, meanwhile use of organic solvent can be reduced, the safety risk is lowered, pollution to the environment is reduced, and operation time can also be shortened; preprocessing time is long through a high performance liquid chromatography method, and it is difficult to conduct synchronous operation; by means of the method, six samples can be placed in a device at the same time, the device can regulate the start time of each sample automatically, the hatching period is 20 minutes, and time in a detector is within 4 minutes.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a rapid detection method for ligustrazine in 8° balsamic vinegar. Background technique [0002] The detection method of ligustrazine in existing vinegar is mainly high-performance liquid chromatography, such as the detection method of ligustrazine in Shanxi mature vinegar stipulated in GB / T 19777-2013, the method first carries out sample treatment, and then uses high-performance liquid chromatography detection. The sample treatment is as follows: first adjust the pH of the sample to > 8.0 with sodium hydroxide solution, add chloroform and repeat the extraction twice, then extract with hydrochloric acid, and finally filter through the membrane for later use. [0003] This method has the following disadvantages: first, the process is cumbersome and repeated extraction is required; second, the error is relatively large, and the process is mostly manual; third, the orga...
