Novel zero card sweetener and preparation method thereof
Technical field
The invention belongs to sweetener technical fields, are specifically related to novel zero card sweetener of one kind and preparation method thereof.
Background technique
Zero card sweetener is not due to containing heat, taste novel and unique, and appearance is mostly beautiful crystalline lens, can be widely applied
In fields such as the additions of the hot drinks such as coffee, the adjustings of mensal sweetening, have a extensive future.
In recent years, the market demand of deepening continuously with health of people diet theory, zero card sweetener also increases year by year.
Research about this respect is also more and more.
Antierythrite is made by glucose fermentation, is white crystalline powder, and crystal is cube structure, not easy to moisture absorption,
Sweet taste is tasty and refreshing and heat is extremely low, is not involved in glycometabolism and causes blood glucose rise, is suitable for numerous food.
New hesperidin methyl dihydrochalcone is by citrus natural component neohesperidin or naringin through bioconversion or chemistry
Obtained low heat value sweetener is converted, there is sweetened, flavouring, flavour enhancing and covers the flavour properties such as bitter taste;There is antioxygen simultaneously
The physiological activity such as change, norcholesterol, hypoglycemic, are widely used in the fields such as food, drug, functional food and feed;Its taste
Pure and have fragrance, entrance is pleasant salubrious.
Zero currently known card sweetener has the compounding of antierythrite and steviol glycoside, there is antierythrite and mogroside
Compounding, crystallization processes are also cocrystallization.But since steviol glycoside and mogroside are soluble easily in water, to cocrystallization
Technical requirements are higher, it is difficult to guarantee crystal beauty, ideal yield coefficient, the suitable cooperative achievement of sugariness.
Existing zero acarbose single variety, taste alternative is less and cocrystallization yield is low, therefore, needs to explore a kind of new
Zero card sweetener of type, more, the ideal yield coefficient of taste alternative.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of novel zero card sweetener, the sweetener crystal
Beauty, sugariness is suitable, does not contain heat, simple and easy to get, high income, is widely used in coffee, hot drink, can also do dining room, home-use
Flavouring sugar;The present invention goes back while providing preparation method.
Novel zero card sweetener of the present invention, in terms of weight fraction, raw material composition is as follows:
90-99.8 parts of antierythrite
New 10-0.2 parts of hesperidin methyl dihydrochalcone.
Wherein:
The antierythrite purity > 99.5%.
The new hesperidin methyl dihydrochalcone purity > 96%.
The preparation method of novel zero card sweetener of the present invention, comprising the following steps:
(1) deionized water is warming up to 65-80 DEG C, and new hesperidin methyl dihydrochalcone, stirring and dissolving is added;
(2) 70 DEG C -90 DEG C are warming up to, antierythrite is added, stirring and dissolving obtains clarification mixed solution;
(3) clarification mixed solution is slowly stirred and is cooled to -2 DEG C~-10 DEG C, continued to be slowly stirred 4-10 hours, obtain
The cocrystallization product of antierythrite and new hesperidin methyl dihydrochalcone.
Wherein:
Deionized water dosage is the 60%-80% of antierythrite and new hesperidin methyl dihydrochalcone total weight.
It is to be cooled to 0 DEG C~-2 DEG C with the speed of 2-3 DEG C/min that cooling is slowly stirred described in step (3), is slowly dropped
What the purpose of temperature was conducive to crystal sufficiently grows molding.
Continue to be slowly stirred 4-10 hours described in step (3) and specifically be stirred 4-10 hours with the revolving speed of 30r/min.
Antierythrite and new hesperidin methyl dihydrochalcone are mixed according to 90-99.8 parts and 10-0.2 parts of ratio,
The crystal shape and color that antierythrite transparent rules can be sufficiently kept in this amount ranges, if beyond this ratio
Crystal should not be at regular shape, and chalcone is excessive, whole system occurs yellowish.
Obtain after the clarification mixed solution of new hesperidin methyl dihydrochalcone and antierythrite with the speed of 2 DEG C/min into
Row slow cooling is to 0 DEG C~-2 DEG C, and system is uneven if cooling is too fast, and two kinds of substances can be easily separated, and cannot form cocrystallization.
The slow then crystal that cooled down be precipitated after since molecular separating force is formed compared with big lumps.
0 DEG C~-2 DEG C are cooled to, because antierythrite is soluble easily in water, is not easy largely to be precipitated under room temperature, and can guarantee to obtain
Biggish yield is obtained, if but being cooled to -3 degrees Celsius hereinafter, system icing, is unfavorable for the formation of cocrystallization product.
The definition of " zero card " refers to the substance of 0 heat or low-grade fever amount.Antierythrite and new hesperidin methyl dihydro look into ear
Ketone is all the sweetener naturally extracted, and all empty calories, the product will not cause eater's change of blood sugar, will not generate heat,
It can be used as zero card sweetener.
Compared with the prior art, the present invention has the following beneficial effects:
(1) novel zero card sweetener of the present invention, using antierythrite and new hesperidin methyl dihydrochalcone into
Row compounding compares steviol glycoside and mogroside, and there are two unique advantages for new hesperidin methyl dihydrochalcone tool, first is that
It is not readily dissolved in cold water, cools down and is easily precipitated;Second is that sugariness is high, it is 3-5 times of steviol glycoside and mogroside.
(2) novel zero card sweetener of the present invention, sugariness selectivity is more, does not contain heat, is widely used in coffee, heat
Drink, can also be cooked dining room, home-use dining table sugar for seasoning.
(3) novel zero card sweetener of the present invention, preparation method is simple and easy to do, and yield reaches 90% or more, ties altogether
Jingjing body is beautiful uniform, has good economy.
(4) the novel zero card sweetener that is prepared of the present invention, sugariness can reach sucrose 1-50 times is even higher, single
Antierythrite sugariness there was only the 60% of sucrose, it is known that be that cocrystallization improves sweet tea to new hesperidin methyl dihydrochalcone therewith
Degree.
