Embodiment 1

[0049] A method for quickly identifying the quality and processing method of jujube slices, comprising the following steps:

[0050] A Establishment of quality sensory evaluation method for jujube slices with different processing methods

[0051] Invite 20 reviewers who have experience in eating jujubes to form an evaluation team, train the evaluation team according to the purpose of the sensory evaluation experiment, the standards and requirements of the sensory evaluation, randomly number the samples, and the sensory evaluation team will score objectively and independently. The interval between the evaluations of each sample was 2-3 minutes, rinse mouth with clean water, and do not communicate and discuss with each other.

[0052] Specifically: test the aroma quality of 16 samples of jujube slices obtained by different processing methods

[0053] Quantitative scoring method is adopted: 8-10 points indicate that the aroma of red dates is particularly strong; 6-8 points indic...

Abstract

The invention belongs to the technical field of food detection, and in particular relates to a method for quickly identifying the quality and processing technology of jujube slices. The method of the present invention comprises the following steps: A: establishing a database of volatile organic compounds in jujube slices with different processing techniques; B: sensory evaluation of the quality of jujube slices; C: analyzing jujube using a statistical method combining principal component analysis and sensory evaluation Tablet quality and volatile compound data to achieve rapid identification of quality and processing methods. The beneficial effects of the present invention are: (1) The samples can be tested directly without pretreatment; (2) The detection speed is fast and the accuracy is high; (3) Not only the data related to the quality characteristics of jujube slices can be obtained, but also the How the slices are processed.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a method for quickly identifying the quality and processing technology of jujube slices. Background technique [0002] Jujube is rich in nutrition, containing 2.92% protein, 0.96% crude fat, 55%-80% polysaccharide, 2.41% crude fiber and various vitamins and minerals. It is an important nourishing food and medicinal food, and an important raw material for the food industry. ,a lot of uses. Traditional Chinese medicine believes that jujube has the functions of strengthening the spleen, nourishing the stomach, nourishing blood, protecting the liver, replenishing qi, and calming the nerves. It has been a good health product since ancient times. In recent years, except for a small number of varieties that are eaten fresh and processed into by-products, most of the red dates are made into dried products for sale. Among them, jujube slices have become a must-have he...
