Abstract

Electron beams were employed to irradiate liquor samples in various doses to study aging effects.Five samples which had been stored for 1, 2, 4, 6, 8 years were exposed to 500, 750, 1 000, 1 250, and 1 500 Gy doses of electron beams (1.5 MeV/u). After irradiation, liquor samples were scanned spectrophotometrically from 200 nm to 400 nm. According to the difference of the UV spectra, the spectral curve similarities from 280 nm to 300 nm and the change regulations were analyzed. The results showed that the less spectral curve similarities between control samples and irradiation samples were, the better the aging effects of liquor were;The longer the liquor were stored, the lower doses were required to reach the optimum aging effect. For eight year stored liquor, the dynamic balance of liquor system was broken and the monomer material increased when the doses were more than 750 Gy, which implied the retrogradation of liquor aging phenomena were clear. In conclusion, the electron beam irradiation has significant aging effect on short year Luzhou-flavor liquor and is an effective method for aging liquor.
