Abstract
The invention discloses the production decision of a kind of low molten residual turmeric paste, in pending turmeric paste crude extract, add acid solution, after the residual operation of precipitation, obtain low molten residual turmeric paste.Present invention process is simple, easy to operate, and the turmeric paste total solvent residual obtained effectively is removed to below 10ppm, improves the turmeric paste safety as a kind of food additive.
Description
Technical field
The invention belongs to natural extract technical field, be specifically related to the production method of a kind of low molten residual turmeric paste.
Background technology
Rhizoma Curcumae Longae is the perennial herbaceous plant of Zingiberaceae, is the traditional medicine of a kind of integration of edible and medicinal herbs, the Rhizoma Curcumae Longae contained in Rhizoma Curcumae Longae
Element, acts not only as a kind of natural pigment and eats, and have the physiology merit such as antiinflammatory, anticancer, antioxidation, antibacterial, antiviral
Can, the treatment to multiple disease has obvious effect.
At present, main employing organic solvent extraction extracts active ingredient from Rhizoma Curcumae Longae, is typically chosen methanol or ethanol etc.
Extraction solvent, first by Rhizoma Curcumae Longae grinds, is subsequently adding extraction, refilters, concentrated extracting solution, obtains rich in curcumin etc.
The turmeric paste of active ingredient, in turmeric paste, curcumin is relatively easy to form crystallization, and solvent is formed package status, causes
Difficulty removed by solvent.Conventional solvent removal method is used to be difficult to reduce dissolvent residual in turmeric paste further, current row
Total solvent residual (including all dissolvent residuals that ethanol and acetone etc. can detect) of turmeric paste in the industry is at 1000-
About 5000ppm, some is the highest, and health is caused latent as food additive by the turmeric paste of relatively high solvent residual
In harm.Simultaneously because solvent residual amount in turmeric paste is high, cause with its curcumin gone out for feed purification molten residual also
Higher, directly affect the curcumin normal use as food additive.
Substantially have no report currently, with respect to reducing the document of dissolvent residual in turmeric paste, therefore, urgently develop in industry
A kind of low molten residual turmeric paste production method, improves the curcumin safety as food additive.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides the production method of a kind of low molten residual turmeric paste, this method
The product solvent residual amount obtained is low, simple to operate, it is easy to accomplish industrialization.
The production method of the low molten residual turmeric paste that the present invention provides, concrete operation step is as follows: soak to pending Rhizoma Curcumae Longae
Cream crude extract adds acid solution, after the residual operation of precipitation, obtains low molten residual turmeric paste.
In the residual operating process of precipitation of the present invention, material is continually fed into the nitrogen of 80-100 DEG C.
Acid solution of the present invention refers to that mass concentration is 0.5-1% hydrochloric acid or vinegar aqueous acid, and addition is that curcumin is thick
The 3% of extract weight.
In step of the present invention (4), the residual condition of precipitation is vacuum >=0.09Mpa, residual temperature 85-95 DEG C of precipitation, de-
The molten 1-3 hour residual time.
The production method of turmeric paste crude extract of the present invention, concrete operation step is as follows:
(1) Rhizoma Curcumae Longae raw material is gone the removal of impurity, then pulverize and obtain curcuma powder；
(2) curcuma powder is dipped in acetone soln, extracts and be filtrated to get Rhizoma Curcumae Longae extracting solution；
(3) extracting solution evaporation and concentration obtains turmeric paste crude extract.
In step of the present invention (1), after Rhizoma Curcumae Longae raw material goes the removal of impurity, pulverized 20 mesh sieves, obtained curcuma powder.
In step of the present invention (2), single-trial extraction curcuma powder quality and acetone volume ratio are 1:5-10, described quality list
Position is kg, and described volume unit is L.
In step of the present invention (2), Extracting temperature is 40-45 DEG C, extraction time 5-7 time, each extraction time 0.5-1
Hour.
In step of the present invention (3), extracting solution evaporation in vacuo degree 0.05 ± 0.005Mpa, evaporating temperature 70 ± 1 DEG C, will
Extracting solution be evaporated to condensing tube without lime set till.
In the present invention, the dissolvent residual detection method of turmeric paste is with reference to " GB1886.60-2015 food safety country mark
Quasi-food additive-Rhizoma Curcumae Longae " the middle dissolvent residual detection method specified, but detection data include that ethanol and acetone etc. can be examined
The all dissolvent residuals surveyed, the dissolvent residual master in current industry in turmeric paste, in addition to normal hexane, isopropanol, ethyl acetate
If ethanol and acetone.
Owing to curcumin molecule has a keto-acid and two kinds of tautomers of enol form, intramolecular or and solvent molecule between easily
Formed hydrogen bond, the present invention utilizes the above-mentioned physicochemical property of turmeric paste, concentration process add acid solution, reduce curcumin molecule with
HYDROGEN BOND INTENSITY between solvent molecule, optimizes the residual technology of vacuum desolvation simultaneously, accelerates the subtractive process of solvent, is successfully soaked by Rhizoma Curcumae Longae
The molten residual of cream is down to below 10ppm, while improving turmeric paste edible safety, preserves turmeric paste Central Plains to greatest extent
Some biological active substanceies having, make product have safety, trophism and functional concurrently.
Use and have the beneficial effects that produced by technique scheme: the dissolvent residual of (1) turmeric paste is effectively removed to
Below 10ppm, substantially increases turmeric paste and adds the edible safety of pigment as a kind of food additive.(2) present invention is passed through height
Temperature nitrogen, can reduce the crystallization rate of curcumin, accelerate the subtractive process of solvent simultaneously, and the precipitation residual time is short, effectively protects
Active ingredient in turmeric paste, the curcumin yield more than 98% in turmeric paste.(3) simple to operate, it is easy to accomplish industry
Change.
