摘要
本实验主要探讨了热敏性纯猕猴桃汁经100～500MPa超高压处理后品质的变化情况。考察的指标有果汁色泽、黏度、pH、单宁、总酸、果胶、总VC、蛋白质以及可溶性固形物,并与未经超高压处理的果汁对照品进行了比较。实验结果表明,超高压处理能较好保持果汁原有的品质和风味,但有些现象还需要进一步从理论上探讨。
This study mainly discussed the quality changes of thermosensitive fresh Kiwi juice by UHP processing with 100-500 MPa. The variation of juice color, viscosity, pH value and tannin, total acid, pectin, total VC, protein and soluble solids content were investigated. The treated and untreated juice were compared with each other, The experimental results showed that the treated kiwi can keep the original juice quality, yet the mechanism still need discussing theoretically.
