Determination of the aging degree on flour food, used to measure by TA-XT2i texture analyzer, Differential Scanning Calorimetry(DSC), X-ray, Raman spectroscopy, Nuclear magnetic resonance spectroscopy, and α-amylase methods. But the these methods need expensive equipment, a lot of inspection instruments and reagents, well practicing operator, high maintenance costs. A flour food aging degree measuring device, the instrument adopts the electric motor control, can automatically measure and record from the field measurement data, overcomes the disadvantages of the above methods, manual and mechanical device operation in one, just simple training can operation, less subsidiary consumables can meet the laboratory use, and can be popularized and used in the small scale enterprise.
