Embodiment 2

[0140] This embodiment describes in detail the food brittleness tester and testing method based on coupling bionics in conjunction with the accompanying drawings:

[0141] figure 1 It is a schematic diagram of the structure principle of the bionic brittleness tester, figure 2 It is a food brittleness test process, as shown in the figure, the brittleness test process of the present invention is mainly to simulate the process of human eating, chewing, and perception. Firstly, the auxiliary mechanism sends the food block into the bionic mandible, and then the driving mechanism sends the food block into the tooth and maxillofacial surface of the bionic mandible, and at the same time pulls the bionic masticatory muscles to drive the bionic upper jaw to realize chewing and crushing movement in the bionic temporomandibular joint; during this process The medium temperature and humidity environment component inputs artificial saliva to the bionic teeth and food block, and maintains a...

Abstract

The invention discloses a coupling-bionics-based food crispness tester which comprises a chewing simulator, a cracking signal acquisition system and a data processing and analysis system, wherein the chewing simulator is used for simulating the food chewing of a human chewing system; the cracking signal acquisition system is used for acquiring a pressure signal and a sound signal, which are generated during the chewing of the chewing simulator; the data processing and analysis system is used for receiving the signals, and performing data processing and analysis to acquire a predetermined food crispiness result. The coupling-bionics-based food crispness tester is established by simulating the human chewing system and an auditory system by a bionic technology, and is used for acquiring mechanical and acoustic signals when the food is chewed, establishing a sensory crispness evaluation and mechanical and acoustic signal prediction model and comprehensively determining the crispness of the food by utilizing the model; an integrated manual technical system with the characteristic of achieving maximum environmental adaptability with low energy consumption is constructed; a test is carried out from a crispness formation mechanism, and is superior to crispness evaluation from other indexes such as cracks and simply from the mechanical signals.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a food brittleness tester and a test method based on coupling bionics. Background technique [0002] The brittleness of food is an important sensory index of food, which has an important impact on the freshness, storage and safety of food materials. At present, the determination of food brittleness mainly includes sensory evaluation method and instrumental method. Sensory evaluation is the most accurate evaluation method of brittleness through human beings' perception of force and sound when chewing food, and then analyzing and judging. However, sensory evaluation not only requires evaluators with certain judgment ability, but also the evaluation process is time-consuming and labor-intensive, and the result is also subject to subjective factors, so the evaluation is very unstable. The instrumental methods for measuring brittleness include general-purpose food texture analyzer and ...
