Abstract
The invention discloses the method for from red pimento, extracting pimento red pigment.This method is directly pulverized red pimento aquatic foods or that do, soaks with organic solvent, removes by filter the pimento slag, and the distillation soak solution is removed organic solvent and just obtained pimento red pigment.This pigment is used for the tinting material of food or medical treatment.The present invention has raw material sources and enriches, and production technique is simple, and is free from environmental pollution, with low cost, is difficult for introducing characteristics such as impurity.Have bigger using value and tangible economic benefit.
Description
The invention relates to the extracting method of a kind of tinting material pimento red pigment that is used for food or medicine.
Because the toxic continuous discovery of synthetic colour, countries in the world use the amount of synthetic colour to reduce day by day in food and medicine industry, and nontoxic, harmless and have the food plant pigment of certain nutrition to increase day by day.The capsanthin that current people are developing and producing is exactly wherein a kind of.Capsanthin is an oil-soluble pigment, and its bright-colored, good stability as food or medical tinting material, is subjected to people's welcome deeply.
Capsanthin is extracted from red pepper, owing to contain peppery element in the red pepper, this peppery element will contain 100,000 in food/, just make the people feel that stronger pungent is arranged, therefore need remove peppery technology from red pepper, extracting haematochrome.This arts demand removes peppery equipment and pepper removing agent, and pepper removing agent is that pharmaceutical chemicals also will be removed pepper removing agent in the operation of back, removes in the peppery process and also loses and destroy a certain amount of pigment.Therefore, extract haematochrome and have complex process from red pepper, the raw material ratio red pimento yields poorly, cost height and easily introduce deficiency such as impurity.
It is simple to the objective of the invention is to seek a kind of technology, and it is abundant need not remove peppery operation, raw material sources, the haematochrome production method of similar again capsanthin color with low cost and performance.
To achieve these goals, the present invention has adopted the method for extracting haematochrome from red pimento to realize.Because of red pimento is compared with red pepper, it is not except that containing peppery element, and other composition is close.
This law is at first pulverized red pimento, adding organic solvent ethanol or acetone or sherwood oil then in the red pimento of pulverizing soaks, and constantly stir, after the immersion pimento slag is removed by filter, soak solution is distilled under 60-90 ℃ condition again and remove organic solvent, the gained enriched material is a pimento red pigment.
When extracting pimento red pigment with aforesaid method, need control to pulverize proportioning, soaking temperature, soak time, filter cloth specification, distillation temperature and the pressure of granularity, red pimento and the organic solvent of red pimento, the present invention controls following technical qualification.
The granularity that red pimento is pulverized, can select diameter for the red pimento of aquatic foods is the 2-3mm size, is crushed to 24-40 order size for the red pimento of doing.
The proportioning of red pimento and organic solvent is the 1(kilogram): the 4-6(liter), that is to say that adding 4-6 in 1 kilogram of red pimento rises organic solvent.Used organic solvent is this one of them of three kinds of ethanol, acetone, sherwood oil, because ethanol does not have poison, price is lower, and preferred alcohol of the present invention is made solvent.
Soaking temperature is 40-50 ℃, in order to increase the immersion effect, can constantly stir in the immersion process.
Soak the used time, be 3 hours at every turn.Every batch of red pimento need soak 3 times and be advisable.Filtrate after every batch of first and second time is soaked is gone the distillation process distillation, soaks rear filtrate for the third time and is added in the next batch red pimento powder and soaks the first time as second batch of material.The organic solvent that distillation process steams reclaims usefulness again, and solvent can use 3-4 time repeatedly like this.
Removing the method for pimento slag can separate with the deep bed filter filtration or with whizzer, and the specification of filtering used filter cloth is a 200-250 purpose filter cloth.
Temperature during distillation is selected the temperature between 60-90 ℃ for use, and distillation can be adopted the method for normal pressure or underpressure distillation under this temperature condition, will keep the soak solution boiling when adopting underpressure distillation just between 60-90 ℃.Till distillation is concentrated into viscous liquid.
With the pimento red pigment that aforesaid method is produced, product quality indicator reaches the standard of capsanthin, and some leading indicator is better than capsanthin, and quality product meets the requirement of food dye, can add food or medical shell is painted according to expense.
The present invention and the existing method of extracting haematochrome from red pepper relatively have red pimento source abundant (per mu yield of red pimento is more than 5 times of red pepper), cost of material is low, production technique is simple, economize and remove peppery operation and remove the pepper removing agent operation, shorten the production time, low cost product, be difficult for advantages such as introducing impurity.Pimento also can be purchased the red pimento of throwing away when eating as vegetables at ordinary times except special plantation purchase.Because the vegetable grower whenever plucks a collection of pimento, always have many red pimentos to take, it is believed that red pimento old be reluctant to eat, it is thrown away much, so promptly waste and contaminate environment, this invention has been arranged after, also the red pimento that these can be taken is at ordinary times purchased the extraction haematochrome.
Example 1
The ethanol that in 500 grams, 24 purpose red pimento powder, adds 3 liter 95%, under 50 ℃, added heat soaking 3 hours, when soaking, stirred 5 minutes every 10 minutes, filter with 250 order nylon filter clothes, to filter out red pimento and repeat to soak (soaking conditions is the same) again twice, be heated to 75 ℃ ± 2 underpressure distillation and remove ethanol filtering the ethanolic soln that contains haematochrome obtain for three times, make the thick red pimento haematochrome of 100 grams.After reclaiming, can continue by ethanol to use.Gained pimento red pigment leading indicator such as following table:
| The present invention extracts the index of pigment | |
| Outward appearance absorbancy (E 1% 1cm455nm) plumbous (%) ash content (%) moisture (%) Residual ethanol (%) abnormal toxicity test (0.2g/kg) of arsenic (%) | Aubergine viscous liquid 〉=57 do not detect (silver salt method) do not detect (dithizone method)≤1.0≤6.0≤0.5 nontoxic, do not have a unusual phenomenon |
Example 2
At 1 kilogram of diameter is to add 4 liter of 95% ethanol in the scarlet pimento of 2-3mm size, adds heat soaking 3 hours under 40 ℃, stirs 5 minutes every 10 minutes when soaking.Filter with 250 order nylon filter clothes, the red pimento that filters out is repeated to soak (condition is soaked identical with the first time during immersion) again twice.Three filtering ethanolic solns that contain haematochrome are heated to 75 ℃ ± 2 underpressure distillation remove ethanol (ethanol recovery), make 50 gram pimento red pigments, it is identical with example 1 gained index to analyze its index.
