Sugar-reduced sweetener product, preparation method therefor, and application thereof

A sugar-reduced sweetener, comprising a high-intensity sweetener, a bulk sweetener and a sugar sweetener, wherein the dosages of the high-intensity sweetener and the bulk sweetener satisfy a condition that a combined sweetness of the high-intensity sweetener and the bulk sweetener accounts for 30% or less of a sweetness of the sugar sweetener,

• wherein the high-intensity sweetener comprises mogroside V, 11-O-mogroside V, mogroside VI, and siamenside I at the mass ratio of (50-60):(5-10):(3-7):(0.4-1);
• the bulk sweetener is erythritol,
• the sugar sweetener is white granulated sugar, and
• the sugar sweetener accounts for 10-50% by weight in the sugar-reduced sweetener,
• wherein the sugar-reduced sweetener is prepared by a preparation method comprising the steps of:
• S1:
• dissolving the high-intensity sweetener and the sugar sweetener in hot water to form a mixture, filtering the mixture with a ceramic membrane to obtain an adhesive;
• S2:
• heating and mixing the bulk sweetener into a fluidized bed of a boiling granulator;
• S3:
• spraying the bulk sweetener with the adhesive 3-5 times during the heating and mixing, wherein the amount of a subsequent spray decreases less than 25 wt % of the amount of an immediately preceding spraying;
• a first mixing time is not less than 30-60 minutes and a time for each subsequent mixing is increased by 10-30 minutes;
• and
• S4:
• drying and cooling the mixture to obtain the sugar-reduced sweetener.
