In the prior art, mostly the generation sugar that uses in tea beverage or the coffee is take Sucralose as main sweet composite sweetener, this class composite sweetener also has different with sucrose on mouthfeel, there is front sweet slow, rear sweet and pleasant impression problem heavily, in the time of in being applied to tea beverage or coffee, also can so that the hardship sense in the drink give prominence to, be difficult to cover, thereby so that these drinks can not be accepted by the public and like.
The preparation method of composite sweetener in the prior art, can be by method or the spray-dired method converted products of substep of simple blend, the composite sweetener that the simple blend method makes is with low cost, but be difficult to guarantee that main sweetening material can be uniformly dispersed, and this point can affect the quality of composite sweetener product to a great extent.The spray-dired method of substep is that substep is dissolved in main sweetening material and each auxiliary sweetening material in the deionized water in batches, then the method by the wet spray drying is coated on each composition material on the granular sweetener by spraying respectively, the composite sweetener product sweetness that this method makes is uniformly dispersed, instant capacity is good, quality is better than the composite sweetener product that additive method makes, but its shortcoming is: material loss is large, the loss of especially main sweetening material is larger, machinery equipment power consumption is too high, the cost of product is significantly increased, and therefore this method also has been subject to certain restriction in implementation process.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of with low cost, sugariness is uniformly dispersed and be highly suitable for tea beverage or coffee in the low-sugar-content and low-calorie composite sweetener that uses and preparation method thereof.
Purpose of the present invention is achieved through the following technical solutions:
A kind of low-sugar-content and low-calorie composite sweetener of using in tea beverage or the coffee of being adapted at comprises following percentage by weight composition: stevia sugar RA 97 33.33%～66.67%, antierythrite 15～42%, isomalt 17～50%, citric acid 0.01～0.35%, natrium citricum 0.05～0.2%, lactic acid 0.05～0.44%; Its preparation method comprises following processing step:
1. stevia sugar RA 97, antierythrite and the isomalt that accounts for total amount 40 ~ 60% are dropped in the Multidimensionblender, progression with 600 ~ 1000rpm mixed 25 ~ 40 minutes, the granularity of control mixed material obtains the mixed material of stevia sugar RA 97, antierythrite and isomalt at 80 ~ 130 orders;
2. the isomalt with citric acid, natrium citricum, lactic acid and surplus is dissolved in the deionized water, obtains mixed aqueous solution;
