Description
Technical field
The present invention relates to a kind of food additives, be specifically related to a kind of erythrose alcohols composite sweetener and preparation method thereof.
Background technology
In the last few years, raising along with expanding economy and people's lives wealth, obesity, hypertension, diabetes, carious tooth etc. become the height morbidity among the crowd, and the generation of these high morbidities is considered to especially with the sucrose Excessive Intake substantial connection is arranged with eating habit and diet structure.Therefore, as the sweetener of food additives, one of its development priority is exactly safe, without nutritive value, empty calory or functional high sweetener extremely low in calories.The characteristics of functional high sweetener are use safe, and consumption is few, and sugariness is high, and use cost is generally all far below sucrose, and this also is the power place that Food Science man continually develops novel high-intensity sweetener.At present, approximately 20 kinds of the granted high sweeteners in countries in the world obtain that kind that the majority state approval allows to use mainly contains that saccharin sodium, honey element, 3,4-Dihydro-6-methyl-1,2,3-oxathiazin-4-one 2,2-dioxide potassium salt, Aspartame, Sucralose, alitame, knob are sweet, glycyrrhizin, stevioside, Momordica grosvenori is sweet and Talin etc.These high sweeteners have plenty of artificial synthetic, and are sweet etc. such as Aspartame, Sucralose, knob; What have then is natural extract, sweet etc. such as sky chrysanthemum glycosides and arhat.No matter be artificial synthesis edulcorant or natural extraction sweetener, at sugariness, sweet taste, stable aspects its pluses and minuses arranged respectively all, therefore, want to give full play to the optimal efficacy of these sweeteners, reduce cost, the most frequently used means are exactly compound at present.By carrying out various sweeteners or sweet substance compound, bring into play may exist between the various sweeteners synergistic function, to as far as possible approaching or satisfy the requirement of desirable sweetener: safety non-toxic, sweet taste is pure similar to sucrose (this is to be popular generally accepted sweet tastes), high sugariness, low heat value or without calorific value, stable high, unlikely dental caries, reduction cost.
Composite sweetener take Sucralose as main sweetening material in the prior art, can process by method or the spray-dired method 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 Sucralose 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.
