摘要: The aim of this study was to investigate the changes of quality attributes of Prunus mume fruits during deacidification using the fermentation of Lactobacillus fermentium. Results of HPLC analysis showed that the sucrose and glucose were dominant sugars, and citric acid was dominant organic acids in P. mume fruits. The level of citric acid reaches 39.3 g/kg, and yet the sucrose and glucose content in the P. mume fruits was very lower, which were 2.16 and 0.66 g/L, respectively. After 8 d of fermentation, sugar and citric acid in the P. mume fruits was completely consumed, and the total phenolics, antioxidant activity (oxygen radical absorbance capacity value), and sarcocarp firmness retained 64.4%, 70.0%, 62.6%, respectively. Also, the viability counts of L. fermentium in fermentation broth increased slowly, which were near 8.0 lg CFU/mL after 8 d of fermentation at 30 degrees C. Overall, fermentation with L. fermentium can be applied in deacidification of P. mume fruits, and also the fermented P. mume fruits can meet the standard to be further processed into prune or sauces, and the fermentation broth of P. mume fruits with L. fermentium have a good prospect in the development of probiotic beverage.
