摘要:

研究超微粉碎处理对桃金娘果粉粒径、色度、颗粒形貌、流动性及水溶性等物化性质的影响。结果表明:随着超微粉碎时间的增加,桃金娘果粉粒径逐渐减小、色泽明显改善、质地更加蓬松、形貌渐趋一致,持水力、持油力和膨胀力分别由1.57、0.76 g/g和0.57 mL/g增加至2.46、1.08 g/g和0.89 mL/g,流动性及溶解性明显降低。由此说明,控制好超微粉碎处理条件可以生产出品质特性较好的桃金娘果粉。

Abstract:

This paper aimed to investigate the effect of airflow ultrafine grinding on physicochemical properties such as
particle size, color, particle morphology, fluidity and water absorption of Rhodomyrtus tomentosa fruit powder. The results
showed that particle size of Rhodomyrtus tomentosa fruit powder decreased gradually, and color and texture was improved
significantly with increasing grinding time. Particle morphology became more consistent. Water-holding capacity, oilholding
capacity and expansibility were enhanced dramatically from 1.57, 0.76 g/g and 0.57 mL/g to 2.46, 1.08 g/g and
0.89 mL/g, respectively, but fluidity and water-solubility were reduced remarkably. In conclusion, airflow ultrafine grinding
with suitable parameters can improve the physicochemical properties of Rhodomyrtus tomentosa fruit power effectively.

Key words: Rhodomyrtus tomentosa, fruit power, airflow ultrafine grinding, physicochemical properties
