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

The jaggedness of the compressive force‐displacement relationship of cheese balls®, cocoa puffs® and peanut butter crunch® particles at various moisture contents was determined in terms of their apparent fractal dimension, and the mean magnitude of the power spectrum of their normalized residuals. The plots of these measures versus moisture contents had a characteristic sigmoid shape very similar to that of the corresponding sensory crispness and crunchiness vs moisture content relationships. This close similarity suggests that the jaggedness of the force‐displacement relationship is a manifestation of the same failure events that produce the crispness or crunchiness sensation. (In the context of the tested products the two terms, crispness and crunchiness, were found to be synonymous.) In all three products moisture toughening could be clearly detected instrumentally but only in two there was an unambiguous corresponding increase in the sensory hardness scores. This indicates that at least in certain cereal products moisture toughening can be perceived simultaneously with brittleness loss.

This study evaluated consumer acceptance and purchase intent of nonwheat butter cake formulations prepared with Thai jasmine rice flour. Three nonwheat rice butter cakes were prepared with varying amounts of powdered emulsifier (propylene glycol ester:diacetyl tartaric acid ester of monoglyceride, 8:2) at 0% (product A), 7.5% (product B), and 15% (product C) of the margarine content (15%) in the cake formulation. A commercial wheat-based butter cake served as the control. Consumers (n= 400) evaluated acceptability of 9 sensory attributes using a 9-point hedonic scale. Overall acceptance and purchase intent were determined with a binomial (yes/no) scale. At least 81% of consumers accepted products B and C, of which 42.1% and 47%, respectively, would purchase the products if commercially available. Product A was neither liked nor disliked with an overall liking score of 5.39. The butter cake products were differentiated by textural acceptability (overall texture, softness, and moistness) with a canonical correlation of 0.71 to 0.79. Overall liking and taste influenced overall acceptance and purchase intent. Odor influenced purchase intent (P= 0.0014), but not overall acceptance. The odds ratio of overall liking was 3.462 for purchase intent, indicating the probability of the product being purchased is 3.462 times higher (than not being purchased, P < 0.0001) with every 1-unit increase of the overall liking score. Based on the logit model, overall acceptance and purchase intent could be predicted with 89.3% and 83.3% accuracy, respectively. The study demonstrated feasibility of completely substituting wheat flour with Thai jasmine rice flour for production of butter cake products acceptable to American consumers.

General lexicons have been developed to describe sensory characteristics of soy sauce. However, no study has examined a large sample set of seasoning soy sauce, a subcategory of soy sauce, and developed a lexicon to fully describe its specific sensory characteristics. In this study, a wide variety of seasoning soy sauces (n = 25) were examined by a descriptive panel composed of nine highly trained panelists and a lexicon consisting of 34 attributes was developed. Each attribute was defined and referenced. Results showed that almost all attributes were needed to explain the common sensory characteristics found in seasoning soy sauces. However, five terms may be used occasionally to describe targeted specific sensory characteristics. As compared with published general lexicons of soy sauce, the current lexicon revealed eight new attributes that were specific to seasoning soy sauces. In addition, new references were also developed for some attributes, thus providing new choices of references for researchers. Practical applications Understanding sensory characteristics of seasoning soy sauce, an increasingly popular flavoring ingredient, is very useful for manufacturers to capture or improve product qualities in order to strengthen their competitiveness in the marketplace. A developed lexicon from this study can be used to determine sensory quality of seasoning soy sauces accurately and precisely. The lexicon can also facilitate communication regarding product quality among sensory scientists, product developers, marketing professionals and suppliers.
