Abstract
The present invention extracts melanic method by Semen Sesami Nigrum.Its key is that alkaline leaching liquid acidifying makes the melanochrome flocculation, after the press filtration it is dissolved in yellow soda ash with the melanochrome in the alkaline solution leaching Semen Sesami Nigrum, and evaporate to dryness is made water-soluble melanochrome.Present method adopts nonpoisonous craft, and equipment is simple, less investment, and good product quality, soluble in water, easy to use.Sesame behind the extraction pigment still can be produced sesame oil, reaches comprehensive utilization, reduces cost, the purpose of increasing economic efficiency.
Description
The present invention relates to a kind of is the method that raw material adopts nonpoisonous craft process extraction of natural melanin with the Semen Sesami Nigrum.
The Semen Sesami Nigrum sweet property of distinguishing the flavor of is flat, nontoxic, have invigorating the liver and kidney, benefiting essence-blood, ease constipation dry, promote the production of body fluid, different physiological roles such as hair care, be a kind of traditional effective nourishing food, motherland's medical science is very high to the evaluation of effect of Semen Sesami Nigrum.It is main relevant with its melanochrome that many physiological functions of Semen Sesami Nigrum are different from white sesame.In addition, fields such as along with science and technology development and human living standard's raising, natural black pigment will be more and more widely be used for that medicine is painted, makeup and foodstuff additive are to substitute synthesis of melanin.Very few in occurring in nature melanochrome kind, so the extraction of natural black pigment is more urgent and needs.At present, extract melanic method by Semen Sesami Nigrum and be not seen in document as yet.
The objective of the invention is to seek a kind of is raw material with the Semen Sesami Nigrum, adopt the method for nonpoisonous craft process extraction of natural melanin, the sesame melanochrome that present method is extracted can make tinting material and other occasions are used, and the sesame substance behind the extraction melanochrome still can be produced sesame oil, the effect that can reach the comprehensive utilization agricultural resource, reduces cost, increases economic efficiency.
Present method technology is simple, less investment, and quality product is excellent, can be water-soluble, easy to use.
The objective of the invention is to realize through the following steps: choosing Semen Sesami Nigrum is raw material, and washing is clean, adds NaOH or Na that concentration is 0.5-5% by a certain percentage
2CO
3Solution soaked 8-24 hour at 25-100 ℃, obtained filtrate after the filtration; Soak again once with similarity condition, merge filtrate twice, its filter residue is cleaned the back oven dry for oil expression usefulness with less water, and filtrate and washings are merged, and adds hydrochloric acid or sulfuric acid and makes it to be acidified to pH value 1-4, at this moment melanochrome flocculation, leave standstill and made its sedimentation in 8-24 hour, drop removes the brown clear liquid in upper strata, and the throw out press filtration is separated, with the less water washing, throw out is dissolved in an amount of Na
2CO
3In the solution, be evaporated to do and just get finished product melanochrome, its productive rate is 1%, the sesame melanochrome that adopts present method to extract is that black has glossy crystalline solid, and is soluble in water, contains As≤2ppm, contain Pb≤5ppm, its absorption spectrum does not have absorption peak in the 400-760nm scope, measure its absorbancy, E at 500nm
1% 1cm〉=20.
The sesame melanochrome powder produced under distance 40w ultraviolet lamp 10cm place illuminate condition, is taken by weighing after 50mg is mixed with the 250ml aqueous solution, measure wavelength 500nm, the variation of measuring absorbancy sees Table 1, with the stability of expression sesame melanochrome to light.
Table 1:
| Irradiation time (hour) | 0 | 2 | 4 | 12 | 18 | 24 |
| The variation of solution absorbance | 0.75 | 0.74 | 0.72 | 0.75 | 0.72 | 0.72 |
Get 50mg sesame melanochrome, be mixed with the aqueous solution of 250ml, pH value is 7.85, and constant temperature was measured wavelength 500nm after 1 hour under assigned temperature, measures absorbancy and sees Table 2, with the stability of expression sesame melanochrome to heat; And through further confirmation of thermal weight loss experiment, its extrapolation decomposition temperature reaches 232.2 ℃.
Table 2:
| Temperature | Do not heat | 42℃ | 61℃ | 78℃ | 98℃ |
| Absorbancy | 0.70 | 0.68 | 0.70 | 0.70 | 0.72 |
Choose sesame melanochrome 50mg and be mixed with the 250ml aqueous solution, pH value is 8.10, measures wavelength 500nm, and the placement different time is surveyed its absorbancy and seen Table 3, to represent sesame melanochrome aqueous solution prolonged preservation at room temperature.
Table 3:
| Place fate | 0 | 60 | 120 | 150 |
| Absorbancy | 0.82 | 0.81 | 0.79 | 0.80 |
Example 1
The Semen Sesami Nigrum of water intaking wash clean is by Semen Sesami Nigrum and Na
2CO
3Solution adds 1%Na by 1: 3 amount
2CO
3Solution at room temperature soaked 17 hours, solution is leached the reservation filter residue use 1: 2 amount to add 1%Na again
2CO
3Solution soaking 6 hours leaches reservation with solution, and filter residue leaches solution and keeps with 1: 1 amount cold water washing, merge three times filtrate, add hcl acidifying, the melanochrome that is settled out was left standstill 12 hours to PH1～4, make its layering, absorb behind the supernatant liquid suction filtration again, throw out is dissolved in 1～5%Na
2CO
3In the solution, the filtering insolubles, pulverize the oven dry back, promptly gets product.
Example 2
The Semen Sesami Nigrum of water intaking wash clean, amount by Semen Sesami Nigrum and NaoH solution 1: 3～5 adds 0.25～1%NaOH solution, under 30～60 ℃ temperature, soaked 4～12 hours, leach solution and keep, filter residue added 0.25～1%NaOH solution soaking 4～12 hours by 1: 2 amount again, leached the solution reservation, filter residue adds 30～60 ℃ water washing again in 1: 1 ratio, leach solution and keep, merge three times filtrate, be acidified with acid to PH1～4.The melanochrome that is settled out left standstill made its layering in 12 hours, inhale remove supernatant liquid after, press filtration is again washed with a small amount of water purification, according to a certain percentage throw out is dissolved in 1～5%Na
2CO
3In the solution, the elimination insolubles, pulverize the oven dry back, promptly gets product.
Sesame substance behind the extraction pigment washes with water to nearly neutrality, and oven dry is used for squeezing sesame oil.
