A major drawback of conventional descriptive profile (CDP) in sensory evaluation is the long time spent in panel training. Rapid descriptive methods (RDM) have increased significantly. Some of them have been compared with CDP for validation. In Health Sciences, systematic reviews (SR) are performed to evaluate validation of diagnostic tests in relation to a gold standard method. SR present a well-defined protocol to summarize research evidence and to evaluate the quality of the studies with determined criteria. We adapted SR protocol to evaluate the validation of RDM against CDP as satisfactory procedures to obtain food characterization. We used "Population Intervention Comparison Outcome Study - PICOS" framework to design the research in which "Population" was food/ beverages; "intervention" were RDM, "Comparison" was CDP as gold standard, "Outcome" was the ability of RDM to generate similar descriptive profiles in comparison with CDP and "Studies" was sensory descriptive analyses. The proportion of studies concluding for similarity of the RDM with CDP ranged from 0% to 100%. Low and moderate risk of bias were reached by 87% and 13% of the studies, respectively, supporting the conclusions of SR. RDM with semi-trained assessors and evaluation of individual attributes presented higher percentages of concordance with CDP.
传统描述性分析（CDP）在感官评估中的一个主要缺点是小组培训所花费的时间长。快速描述性方法（RDM）的使用显著增加。其中一些方法已经与 CDP 进行了比较验证。在健康科学领域，系统评价（SR）用于评估诊断测试相对于金标准方法的验证。SR 制定了明确的方案，以总结研究证据，并使用确定的标准评估研究的质量。我们采用 SR 方案来评估 RDM 对 CDP 的验证，以确定其作为获取食品特征描述的满意程序。我们使用“人群干预比较结局研究 - PICOS”框架来设计研究，其中“人群”是食品/饮料；“干预”是 RDM，“比较”是 CDP 作为金标准，“结局”是 RDM 生成与 CDP 相似描述性轮廓的能力，“研究”是感官描述性分析。得出 RDM 与 CDP 相似的研究比例从 0%到 100%不等。87%和 13%的研究分别具有低和中度偏倚风险，支持了 SR 的结论。使用半训练评估员的 RDM 和个体属性评估与 CDP 具有更高的一致性百分比。
