White asparagus is one of the 30 vegetables most consumed in the world. This paper unifies the stages of their sensory quality control. The aims of this work were to describe the sensory properties of canned white asparagus and their quality control and to evaluate the applicability of agglomerative hierarchical clustering (AHC) for classifying and monitoring the sensory quality of manufacturers.
Sixteen sensory descriptors and their evaluation technique were defined. The sensory profile of canned white asparagus was high flavor characteristic, little acidity and bitterness, medium firmness and very light fibrosity, among other characteristics. The dendrogram established groups of manufacturers that had similar scores in the same set of descriptors, and each cluster grouped the manufacturers that had a similar quality profile.
The sensory profile of canned white asparagus was clearly defined through the intensity evaluation of 16 descriptors, and the sensory quality report provided to the manufacturers is in detail and of easy interpretation. AHC grouped the manufacturers according to the highest quality scores in certain descriptors and is a useful tool because it is very visual. © 2015 Society of Chemical Industry.
白芦笋是全球消费量排名前30的蔬菜之一。本文统一了其感官质量控制的阶段。这项工作的目的是描述罐装白芦笋的感官特性及其质量控制，并评估凝聚层次聚类法（AHC）在对制造商的感官质量进行分类和监测方面的适用性。
定义了16个感官描述词及其评估技术。罐装白芦笋的感官特征包括风味特征浓郁、酸度和苦味较低、硬度适中、纤维质非常少等。树形图建立了在同一组描述词中得分相似的制造商群体，每个聚类将具有相似质量概况的制造商归为一组。
通过对16个描述词的强度评估明确界定了罐装白芦笋的感官特征，向制造商提供的感官质量报告详细且易于解读。AHC根据某些描述词中的最高质量得分对制造商进行分组，因其具有很强的直观性，所以是一种有用的工具。© 2015化学工业协会。
