Comparing 3‐point Versus 9‐point Just‐about‐right Scales for Determining the Optimum Concentration of Sweetness in a Beverage

Abstract: Just -about-right (JAR) scales are often used in research and development of food products. One of their uses is determining the optimum level of an ingredient. The purpose of this work was to compare the use of a 3-point JAR scale analyzing the data using survival analysis statistics with a 9-point JAR scale followed by linear regression analysis. It was also of interest to determine if a concentration range effect exists when determining the optimum concentration using a 3-point JAR scale. Three different c… Show more

“…Sixty milliliters of chocolate milk was poured into 177.4 mL clear plastic tumblers with 3‐digit codes. A 7‐point smiley face scale (1 = super bad, 7 = super good; Kroll ; Guinard ; Li and others ) was used for liking questions, and a 3‐point smiley face scale (1 = not enough, 2 = JAR, 3 = too much) was used for JAR questions (Osornio and Hough ). For 5 to 7 y children, only overall liking was asked after they evaluated each sample and paper ballots were utilized.…”

“…Subsequently, each participant had to judge six sensory properties of the yogurt using the JAR technique and a three-point category scale with check boxes (Meilgaard, Civille, & Carr, 1999). A three-point scale may have some disadvantages as regards scale utilization but was favored because of its simple design, and because its use is more compliant to yes/no decisions in daily life (Lopez Osornio & Hough, 2010). The subjects had no information on that task during acceptability testing so that an impact of the JAR questions on overall liking (Gacula, Mohan, Faller, Pollack, & Moskowitz, 2008) was avoided.…”
