In manufacturing process, melting temperature and viscosity are important properties of glazing sauce and frozen yakitori products. These two properties are generally used to predict frozen-state stability. The research objective was to study the effect of ingredients (sweeteners and thickening agents) on melting temperature and viscosity of yakitori sauce. The study used the primary sauce which only contains the main sauce ingredients including sweeteners, thickening agents and Johin Soy sauce). The sweeteners were mixture of 24-29DE glucose syrup and sucrose (5:25, 10: 20, 15:15 and 20:10 w/w). Thickening agents were modified tapioca starch (SMS757 and TAS110, at 4-5%w), and gum (xanthan gum and guar gum, at 0.1-0.2 %w). The results showed that sweetener with higher glucose syrup concentration gave higher transition temperatures (both Tm and Tg) and a slight decrease in sauce viscosity and Brix value. The melting temperature was found associated with the melting of unbound ice phase and can be observed visibly as an initial state of the sauce melting on product surface. Replacing sucrose (MW=342) with glucose syrup (MW=647) reduced number of dissolved sugar molecules and, thus, allowing ice phase to be melted at higher temperature. Thickening agents (both modified starch and gum, especially TAS110) greatly increased viscosity and amount of sauce taken-up to the product, but did not significantly affect the transition temperatures and Brix value. Results from our study are useful for development of new Yakitori sauce recipes with proper viscosity range and high frozen-state stability.
