Description
Technical field
The present invention relates to the technical field that effective ingredients in plant extracts, in particular to a kind of Extractive of apple pomace fructose.
Background technique
Fructose also known as levulose are a kind of common natural sugars, frequently as the component part of diet.Initially it is from sucrose
It separates, there is content abundant in various fruit and plant.Such as containing about 40% fructose in honey, cherry, banana,
Pears, apple and glucose etc. then contain 5-7%.Fructose is nutritive carbohydrate, does not increase the digestion burden of stomach, through small intestinal absorption
Liver is delivered to by arterial circulation, does not increase blood glucose value, therefore to diabetic, baby, gravid woman, the elderly and patient
Postoperative Intravenous administration, which supplements the nutrients, to be particularly suitable for.Fructose is a kind of monosaccharide, usually thick liquid, soluble easily in water, ethyl alcohol and second
In the prior art there are many extracting methods of fructose, but all there is the problems such as technique is cumbersome, process is complicated, at high cost in ether.
Summary of the invention
It is of the invention the technical problem to be solved is that a kind of Extractive of apple pomace fructose is provided, the present invention uses counter-current
The fructose in apple pomace is extracted, more fully fructose ingredient can be extracted, had compared with art methods
The features such as solvent, extraction efficiency are high, at low cost is saved, industrialized production is suitable for.
The technical proposal adopted by the invention to solve the above technical problems is that: a kind of Extractive of apple pomace fructose, using inverse
Stream extraction method be prepared, the adverse current extraction method the following steps are included:
Step (1): by 85-90 DEG C of boiling 10min of apple pomace, liquid is crushed, low temperature drying；With
Step (2): be added pH value be 1.0-3.0, the ethanol water that mass fraction is 65-85%, adverse current at 30-60 DEG C
4-6h is extracted, merges after filtering and collects filtrate, concentration obtains Extractive of apple pomace fructose.
Further, in the step (2), addition pH value is 1.0, mass fraction is 75% ethanol water, 40
It is countercurrently extracted at DEG C 6 hours.
Further, the fructose content 7.92%~8.17% of the Extractive of apple pomace fructose.
" concentration " described herein is cryogenic vacuum concentration, and temperature is controlled at 10~20 DEG C.The degree of concentration is: making gained
The solid content of final Extractive of apple pomace fructose is controlled the 0.4%~1% of its weight.
Compared with the prior art, the invention has the following advantages:
(1) China is apple production and processing big country, generates a large amount of apple pomace every year, utilizes the apple abundant containing fructose
Slag makees raw material production fructose, has important productive value, therefore the present invention extracts fructose from apple pomace, can improve fructose
Yield can improve the utility value of apple pomace again.
(2) present invention uses adverse current extraction method, can more fully extract to anthocyanin ingredient, with the prior art
Method is high, at low cost compared to having the characteristics that saving solvent, extraction efficiency, is suitable for industrialized production.

Specific embodiment
One, extracting factor is investigated
1, leaching condition is tested
(1) influence of the ethyl alcohol mass percent to fructose compound leaching effect
In industrial production, due to often containing certain moisture in raw material, ethyl alcohol also contains certain moisture after being recycled,
There is very big influence to the leaching of fructose compound in ethyl alcohol mass percent, therefore with different quality percentage Ethyl alcohol aqueous solution pair
Fructose material carries out leaching experiment, with fructose content trace analysis.In ethyl alcohol mass percent to the leaching fructose from raw material
It influences to take 5 parts of raw materials respectively in experiment, every part of 50.00g is tested, with different quality percentage, the ethyl alcohol that pH value is 1.0
Each 200.00ml of aqueous solution extracts 6h, and the relatively amount of gained fructose, result is as shown in Figure 1.
As shown in Figure 1, under the same terms, leaching ability power is followed successively by
75% > 80% > 70% > 85% > 65%, therefore, select 75% ethanol water as leaching agent.
(2) influence of the time of contact to fructose compound leaching effect
Take 6 parts of raw materials respectively, every part of 50.00g, it is each be added mass percent be 75%, the ethanol water that pH value is 1.0
200.00ml is leached, and time of contact is respectively 1h, 2h, 3h, 4h, 5h, 6h, and it is as shown in Figure 2 to leach result.
As shown in Figure 2, at room temperature (26 DEG C), extraction time 6h, Leach reaction basically reaches balance；When extending leaching
Between, leaching rate is basically unchanged.
(3) influence of the temperature to fructose compound leaching effect
Take 6 parts of raw material powders respectively, every part of 50.00g, it is each be added 200.00ml mass percent be 75%, pH value 1.0
Ethanol water, leach at different temperature, extraction time 2h, apple pomace fructose content in sample detection leachate,
As a result as shown in Figure 3.
From the figure 3, it may be seen that the leaching rate of fructose also accordingly increases with the increase of extraction temperature；Reach 40 DEG C in temperature
When, increase temperature, the leaching rate increase of fructose tends to be slow.
2, four sections of adverse current percolations (process diagram is shown in Fig. 4)
It is mounted with that 6 ф 25.4mm × 1000mm glass include mouth pipe altogether, as the leaching of four sections of adverse current diacolation leaching experiments
Device (leaches column), wherein four operations, two are done all conversions.150.00g apple pomace raw material crushed material is packed into every column (referred to as
Raw material, the same below), with metering pump by leaching agent (65-85% ethanol water), first is squeezed into the flow of about 5mlmin-1
Root leaches in column, and 65-85% is with about 1cmmin-1 speed diacolation, after the first column flows out 450ml leachate, by the first column with
Second column is connected.The recent filling that metering pump is squeezed into enters the second column through the first column, outflow；With it is upper identical, when the second column flow out
After 450ml black leachate, the second column and third column are connected.The rest may be inferred, until the 4th column flows out 450ml efflux
Afterwards, the 4th column and the 5th column are connected.Meanwhile metering pump discharge pipe from the first column upper end is moved into the second column upper end and the
Two columns connect (the first column is withdrawn from from system).At this point, new leaching agent, through metering pump into the second column, after three, four, five columns,
It is flowed out from the 5th column, equally takes 450ml leachate；Hereafter, recent filling goes out leachate from the 6th column into third column.Class according to this
It pushes away, constantly circulation four sections of adverse current diacolation leaching experiments of progress are balanced to leaching is reached.The 9th column starts to the 12nd in this test
Column stops, this four columns outflow leachate approximate equilibrium when leachate, therefore when new leaching agent from from the 9th column into, warp
Ten, 11,12 column, and after flowing out 450ml black leachate under the 12nd column, stop leaching test.By nine, ten, 11,
The leachate sampling of 12 columns outflow, inspection measure the content of fructose.(note: cylinder is to be recycled, and nine, ten, ten one, ten
Two only represent label, do not have practical significance)
3, four sections of adverse current diacolation leaching test results
As above-mentioned counter-current is tested.Every part of sample is 150.0g, using 75% ethanol water as leachate, 40 DEG C
Lower extraction 6h, liquid-solid ratio 5.The leachate for taking nine, ten, 11,12 columns to flow out is measured, and the results are shown in Table 1.
1 four sections of adverse current diacolation leaching test results of table
As known from Table 1, in apple pomace fructose content in terms of 6%, then four sections of adverse current diacolation lixiviation process (in terms of leachate) its
Leaching rate reaches 95.0%.
Detection method:
Fructose content measuring method use determined by ultraviolet spectrophotometry, specific measuring method referring to account for up to east ultraviolet point
