Effects of alternative sweeteners with or without xanthan gum on the physicochemical properties of scone products.

ABSTRACT

The physicochemical properties of scones made with alternative sweeteners (stevia, sucralose, and allulose) at different ratios (30, 70, and 100%) with or without xanthan gum were investigated. Nineteen samples were evaluated for crust color, moisture content, specific volume, and texture properties. Scones with allulose had lower L values but higher a and b values due to the Maillard and caramelization reactions. The moisture content increased with xanthan gum addition, thereby decreasing the specific volume. The sample with 30% of stevia (ST30), 30% of sucralose (SC30), and 30% of allulose and xanthan gum (AL30G) had similar characteristics to the sample with sucrose (CON). In the consumer acceptance test, CON was the most preferred, but ST30 showed no significant difference. AL30G was less preferred because of its lack of sweetness. Overall, the physicochemical properties and consumer acceptance of ST30 were closest to those of CON, suggesting its potential use in scone products.
