| 摘 要： | 以蓝莓汁为原料,进行了超高压(UHP)和热力处理对蓝莓汁微生物和理化指标的影响,以及贮藏期内蓝莓汁品质变化的研究。结果表明:超高压可以有效杀灭蓝莓汁中的微生物;超高压处理后,蓝莓汁表现出更诱人的颜色;贮藏期内超高压和热处理对蓝莓汁的总酸、还原糖、可溶性固形物含量影响较小;与热处理相比,超高压处理能更好的保持蓝莓汁中的VC和花青素含量。

| Abstract: | The fresh blueberry was selected as the trial material.Two samples of blueberry juice were sterilized by ultra high pressure(UHP) and thermal treatments respectively.The physicochemical property were analyzed and compared during the storage.The results showed that microorganisms in fresh blueberry juice could be inactivated effectively by UHP.Blueberry Juice showed better color after UHP.UHP had no significant effect on titratable acids,reducing sugar,Brix.Fresh blueberry juice treated with UHP was better than that with heat sterilization not only on VC,but also on anthocyanins. |
