摘  要:
目的:研究高静压(HHP)处理对山竹汁贮藏过程中微生物及品质变化的影响。结果:4℃和常温贮藏4周期间,经HHP处理和高温短时杀菌法(HTST)处理后的山竹汁中无细菌、霉菌和酵母检出。色泽、褐变度、总糖、总酚、可溶性固形物含量和抗氧化性无显著变化,pH和浊度及维生素C含量变化显著(P<0.05);可滴定酸含量在400 MPa处理下无变化,在500MPa处理下显著增加(P<0.05)。结论:HHP处理对山竹汁具有良好的杀菌效果,对贮藏期间产品的某些品质有良好的保护作用。

摘  要:
Effects of high hydrostatic pressure( HHP) on microorganisms and quality attributes of mangosteen juice during storage were investigated.The results showed that no bacteria,yeast and mould were detected during 4-week storage time in mangosteen juice by HHP and HTST.No significant( P > 0.05) changes were observed on color parameters,browning degree,total sugars,total phenols,total soluble solid,antioxidant activity and titratable acidity at 400MPa.However,pH,turbidity,vitamin C content and titratable acidity at 500MPa significantly changed( P < 0.05).It could be concluded that HHP had significant effects on sterilizing and maintaining some quality attributes of mangosteen juice during storage.
