Electric Screener Participates in the Analysis of Effect of Phosphine on Fatty Acid Values ​​in Rice

Phosphine is a fumigating agent widely used in the prevention and control of stored grain pests. It has the characteristics of simple use, good effect, low residue, low toxicity, etc. It is one of the indispensable important agents in the treatment of stored grain pests. Under the action of phosphine fumigation, the productivity and vigor of the microorganisms in the grain piles can be reduced, that is, the effect on the quality of rice grains can be reduced, thereby reducing the increase in the fatty acid value of rice grains. Fatty acid value is one of the most sensitive indicators to evaluate the change of rice storage quality. The changes in fatty acid values ​​of rice under different phosphine fumigation conditions were studied. The effect of different fumigation conditions on the fatty acid values ​​was observed and analyzed. In order to achieve better fumigation parameters.

Major Equipment and Instruments: Electric Filter, Husker, Hammer Cyclone, Adjustable Oscillator, Electronic Balance, Basic Burette, Colorimetric Tube, 150-mL Erlenmeyer, 250-mL Erlenmeyer Erlenmeyer, Short-necked Funnel, medium speed qualitative filter paper and so on.

The changes in rice fatty acid values ​​under different phosphine fumigation treatments were investigated by means of electric filters and other instruments. The results showed that the proper increase of the dosage, the combination of fumigation with fast and slow fumigation, and the appropriate fumigation time can effectively reduce the increase in fatty acid value of stored rice.
