Sensory Lexicon Development Using Trained Panelists in Thailand and the U.S.A.: Soy Sauce

Abstract

Twenty soy sauce products were presented to two sensory panels, one in Thailand and one in the U.S.A. Both panels had extensive training conducting descriptive sensory studies. Neither group had tested soy sauce previously; however, they had different familiarity with soy sauce. Each group separately evaluated samples during the same time period, then met in Thailand to compare and discuss their generated lexicons. Most attributes listed by each group of panelists provided similar definitions and references. Although, a few attributes were not used by one or the other panel because that term either does not exist in both languages (e.g., "cured" is not a term for the Thai panel), represented an uncommon characteristic (e.g., "roaches" for the American panel), or were complex concepts (e.g., "brown"), the panelists used references to assist their understanding of unclear attributes. After discussion, both panels agreed on 59 attributes with definitions and references for a soy sauce lexicon. The article presents attributes in English and Thai. PRACTICAL APPLICATIONSA universal lexicon developed by different groups of trained panelists could reduce confusion and make the lexicon more understandable. A universal lexicon would help researchers in other countries to understand product quality. Additionally, the developed lexicon allows researchers to conduct studies with the same standard method in different laboratories enabling comparable results. bs_bs_banner Journal of Sensory Studies

Consumer Perception of Dry‐Cured Ham – A Cross‐Cultural Study in Italy, Norway and Spain

“…More recently, Cherdchu et al . () showed that panels operating in two different countries and cultures (U.S.A. and Thailand) still used approximately the same terminology to describe the product and generated similar information about the product category.…”

Sensory Characteristics and Comparison of Commercial Plain Yogurts and 2 New Production Sample Options

“…Samples were evaluated by a 6‐person highly trained descriptive panel. This number of highly trained panelists is the same as that published in other recent studies evaluating categories of products (Miller and Chambers ; Cherdchu and others ; Lee and others ). Prior to this study, each panelist had completed over 120 h of general training in the descriptive sensory analysis methodology, which included exposure to dairy products.…”
