The study investigated the effects of high-pressure processing (HPP) (600 MPa/5 min), pasteurization (PT) (85 °C/30 s), and high-temperature short time (HTST) (110 °C/8.6 s) on physicochemical parameters (sugar, acid, pH, TSS), sensory-related attributes (color, aroma compounds), antioxidants (phenolics, vitamin C, carotenoids, antioxidant capacity), and sensory attributes of yellow passion fruit purée (PFP). Compared to the PT and HTST, HPP obtained the PFP with better color, sugar, and organic acid profiles. Although PT was equally effective preservation of antioxidants and antioxidant capacity of PFP compared to HPP, high temperature inevitable resulted in the greater degradation of the aroma profile. The amounts of esters, alcohols, and hydrocarbon in PFP were significantly increased by 11.3%, 21.3%, and 30.0% after HPP, respectively. All samples were evaluated by a panel comprising 30 panelists according to standard QDA (quantitative descriptive analysis) procedure, and the result showed that HPP-treated PFP was rated the highest overall intensity score with 7.06 for its sensory attributes, followed by control (6.96), HTST (6.17), and PT (6.16). Thus, HPP is a suitable alternative technology for achieving the good sensory quality of PFP without compromising their nutritional properties.
该研究调查了高压处理(HPP)(600兆帕/5分钟)、巴氏杀菌(PT)(85℃/30秒)和高温短时处理(HTST)(110℃/8.6秒)对黄色西番莲果泥(PFP)的理化参数(糖、酸、pH值、总可溶性固形物)、感官相关属性(颜色、香气成分)、抗氧化剂(酚类、维生素C、类胡萝卜素、抗氧化能力)以及感官属性的影响。与PT和HTST相比,HPP处理得到的PFP具有更好的颜色、糖和有机酸特征。尽管与HPP相比,PT在保存PFP的抗氧化剂和抗氧化能力方面同样有效,但高温不可避免地导致香气特征的更大程度降解。HPP处理后,PFP中酯类、醇类和烃类的含量分别显著增加了11.3%、21.3%和30.0%。由30名评估员组成的小组按照标准定量描述分析(QDA)程序对所有样品进行了评估,结果表明,HPP处理的PFP感官属性的总体强度得分最高,为7.06,其次是对照组(6.96)、HTST(6.17)和PT(6.16)。因此,HPP是一种合适的替代技术,可在不损害PFP营养特性的情况下实现其良好的感官品质。
