The influence of two different types of inulin added to fiordilatte cheese was assessed on product quality during the proper refrigerated storage period. To this aim, the fresh cheese was produced by a pilot plant, adding inulin, either from chicory (low degree of polymerization) or from cardoon (high degree of polymerization), during the stretching phase of the production process. Microbiological stability, sensory acceptability, texture and color changes of fortified dairy food during storage were measured and compared to the control cheese. Results suggest that inulin from different sources, even if characterized by a different degree of polymerization, can keep the texture and color of fiordilatte during storage. Microbiological analyses highlight that inulin seemed to promote a faster spp. growth; however, the viable cell concentrations were found to be comparable in all the samples after one week. growth was faster when inulin from chicory was used. Sensory analysis shows that inulin addition to fiordilatte promoted the sensory quality preservation during storage; in fact, the fortified cheese overall quality was found to be always higher ( < 0.05) than that of the control sample, thus suggesting that inulin addition to fiordilatte represents a valid strategy for its fiber fortification.
在适宜的冷藏储存期内,评估了添加到菲奥里拉奶酪中的两种不同类型菊粉对产品质量的影响。为此,由中试工厂生产新鲜奶酪,在生产过程的拉伸阶段添加来自菊苣(低聚合度)或刺菜蓟(高聚合度)的菊粉。测定了强化乳制品在储存期间的微生物稳定性、感官可接受性、质地和颜色变化,并与对照奶酪进行比较。结果表明,即使来自不同来源的菊粉具有不同的聚合度,在储存期间也能保持菲奥里拉奶酪的质地和颜色。微生物分析表明,菊粉似乎促进了某种菌的更快生长;然而,一周后所有样品中的活菌浓度相当。使用来自菊苣的菊粉时生长更快。感官分析表明,在菲奥里拉奶酪中添加菊粉可在储存期间促进感官品质的保持;事实上,发现强化奶酪的整体质量始终高于对照样品(<0.05),因此表明在菲奥里拉奶酪中添加菊粉是其纤维强化的有效策略。
