Designing and manufacturing of multifunctional texture analyzer with the ability to analyze textural properties under various controlled temperature and humidity conditions

Texture analyzer is one of the important tools for analyzing and evaluating texture properties including hardness, softness, extensibility, tightness, fragility, adhesiveness, adhesion, compressibility, flexibility, shearability, elasticity, gel strength and springiness In this research, a texture analyzer was designed which, based on software and data processing ideas, while increasing the accuracy of performance and measurements, it provided calibration capabilities to make the output data close to real data  . The main features of the texture analyzer are the ability to carry out the test in controlled temperature and humidity to analyze the texture parameters in order to reduce error in regions with different temperature and humidity. The results of the tests show that by carefully calibrating the calibration process and designing the calibration filter, the accuracy of the analyzerchr('39')s performance is improved to 0.05% of the read value. Also, using the micro-stapling algorithm and the use of the screw mechanism, the movement of the jaw is precisely less than 0.005 mm and the speed of 0.1 millimeter per second is controllable. All of these features, along with the USB connection with any personal computer, will be able to communicate directly with the EXCEL program, and save and simplify data analysis under the EXCEL program. The results of the tests show that there is no statistically significant difference between the relative humidity of the texture analyzer and the relative humidity for each sample (p <0.05). Texture hardness of different samples of biscuits containing resistant starch was evaluated by commercial (C) and designed (D) instrument and there was no significant difference between the hardness of the texture obtained from both devices.
