The invention provides a method for detecting the content of reducing sugar in fermentation materials, which comprises the steps of: a) detecting a sample to be detected with a near infrared analyzer to obtain a near infrared spectrogram of the sample to be detected; and b) analyzing the near infrared spectrogram with the near infrared analyzer according to a preset calibration module to obtain the content of the reducing sugar in the fermentation materials. The method adopts a near infrared analyzing technology, combines the chemical metrology with a computer software technology, and builds the calibration modules to detect the content of the reducing sugar in the fermentation materials, does not need to previously process an analytic sample, does not consume the other materials when analyzing, does not break the sample, and reduces the consumption of the materials. The method can complete a sample analysis task within 2-3 minutes, which needs to be completed more than 1 hour with a normal ...

The invention discloses a method of analyzing moisture for high-moisture corn and frozen corn by near infrared spectrum technique. The method conquers temperature limitation of near infrared spectrum detection, can measure sample which temperature is lower than room temperature by microwave heating treatment besides sample of room temperature. The invention mainly utilizes a near infrared analysis instrument, combines chemometrics method, employs diffuse reflection measuring method, uses certain representative corn as standard sample to establish scaling model, and predicts moisture content of unbeknown sample by the model. Advantages of the invention are nondestructive, easy operation, fast detection speed and higher measurement accuracy.
