Embodiment Construction

[0013] Below in conjunction with accompanying drawing in the embodiment of the present invention, the specific embodiment of the present invention is described in detail:

[0014] 1) Sample processing of yellow peach crisps: Randomly select samples of yellow peach crisps, cut them into samples with a flat surface and a thickness of 7 mm with a small cutting machine, then cut the samples in half, conduct sensory testing on one half, and conduct texture analysis on the other half detection. The yellow peach crisps used for the texture analyzer test are subjected to certain pretreatment: the yellow peach crisps tested by the single compression method, this part of the sample is cut into 20×20×7mm by a small cutting machine; the three-point bending method is used for testing The yellow peach crisps, this part of the sample was cut into 40×20×7mm with a small cutting machine; the yellow peach crisps detected by the puncture method, this part of the sample does not need further proc...

Abstract

The invention discloses a method for detecting the texture of yellow peach crisp chips, and belongs to the field of food texture research. According to the method, a puncture test is carried out on ayellow peach crisp chip sample to obtain a sample stress-time curve, the maximum force Fm (g) and the slope G (g / s) at the maximum force are calculated and can represent the hardness and crispness ofthe yellow peach crisp chip respectively, and texture grading is carried out on the hardness and crispness of the yellow peach crisp chip through sensory scoring. The method can quickly and accuratelydetect the texture characteristics of the yellow peach crisp chips, optimizes the probe combination, and avoids the tedious, time-consuming and labor-consuming probe selection.

Description

technical field [0001] The invention belongs to the field of food texture research, in particular to a method for detecting the texture of yellow peach chips based on a texture analyzer. Background technique [0002] Yellow peaches are rich in nutrients, with a large amount of vitamin C, cellulose, carotene, lycopene, red pigment and various trace elements such as selenium and iron required by the human body. On the basis of maintaining the original flavor, yellow peach crisps can maintain the nutrients of yellow peaches to the maximum extent, and have the advantages of crisp taste and easy storage. The original crispness of yellow peach chips reduces the use value of the product. With the improvement of people's living standards and the acceleration of the pace of life, a fast and efficient method for detecting the hardness and crispness of yellow peach crisps is needed. [0003] The hardness and brittleness of yellow peach chips are closely related to their crispy textur...
