1. principle and use

The freshness meter is a testing instrument for determining the freshness of brown rice and polished rice. During the storage of rice, lipid compounds will be decomposed to generate aldehydes. After the aldehydes react with acid-base indicator, the instrument measures the absorbance of the mixed solution in a certain wavelength range, and uses numerical values to indicate the freshness of rice. Mainly used in rice research, breeding, storage, processing, circulation.

2. measurement items

FD value of rice (Fresh Degree)

3. performance characteristics

1, brown rice, polished rice and free washing rice can be determined. Freshness numerical, easy to determine the deterioration of rice, so you can rule out the possibility of mixing in the deterioration of rice

2, simple operation, rapid determination, can save time. The operation is simpler than the previous fatty acid determination, thus saving time and improving work efficiency; 6 samples can be completed in about 10 minutes

3. The computer screen is displayed in Chinese. Can share a set of management software with rice taste meter and hardness viscometer (form a taste identification group), and implement a series of data management such as data collection, data output and result printing.
