Description
Technical field
The invention belongs to health product technology fields, relate generally to a kind of method for extracting haematochrome from Jasmine flower residue.
Background technique
Edible pigment is also known as colorant, is the food additives by food color and for the purpose of improving food color, with
The rapid development of food industry also increasingly increases the demand of edible pigment.Edible pigment can be divided into people because of its source difference
Work synthetic dyestuff and natural pigment two major classes, with regard to edible pigment application evolution from the point of view of, in the middle of the 19th century before, be apply than
More crude natural pigment is as edible pigment；After in the middle of the 19th century, since synthetic dyestuff is come out one after another, and with it with color
Pool is bright-coloured, and stability is good, strong coloring force, is suitable for toning, and easy to dissolve, quality is uniform, odorless, tasteless and low in cost etc. one
Number of advantages, thus be widely used in food, to increase style and kind and the appetite sense for improving people of food, but with
The increase of the improvement of people's living standards and health care consciousness, the secondary colour that the food such as beverage, candy, cake and drinks are used
More stringent requirements are proposed for element.Past, common secondary colour was known as azo group (- N=N-), it is a kind of chromophoric group, contained this
The compound of kind group is all coloured substance, but many azo-compounds are carcinogenic substances, has different degrees of chronic toxicity
With carcinogenic and teratogenesis.In recent years, it since synthetic dyestuff toxicity is increasingly that people is of interest, is gradually limited in external many developed countries
System is even forbidden to use synthetic dyestuff, and the country also just slowly eliminates its use.Most natural pigments due to edible safety without
Poison, natural in color, many kinds have the effects that physiological activity has certain nutrition and health care and anti-inflammatory concurrently, they retain
Part natural component abundant is such as in plant: vitamin, amino acid, nucleotide, flavonoids and certain required members
Element etc. is not only widely used in the products such as various cosmetics, food, beverage, to help the deviation for correcting color rate and emphasize to indicate
Style possessed by different food products, and the industries such as medicine, health care product are also applicable in, therefore in the international market, natural colour
Plain sales volume annual growth is maintained at 10% or so, so domestic go in for the study develops unit and the personnel of natural food colour
It is increasing, develop and utilize the certainty that natural plant pigment replaces synthetic food color to have become history.With edible secondary colour
Element is compared, and edible natural pigment has following advantages: 1, most natural pigments are nontoxic and without side-effects, highly-safe；2,
Containing nutriment needed by human or itself be exactly vitamin or the object with vitamin property in many natural pigments
Matter, such as riboflavin, beta carotene；3, the natural pigment having has certain pharmacological effect, has prophylactic treatment to certain diseases
Effect, such as rutin sophorin natural edible flavochrome have and make one to maintain the normal resistivity of capillary and to prevent artery sclerosis function
Can, medically always as the ancillary drug and nutritional supplement for treating disease of cardiovascular system；4, the coloring of natural pigment
Tone compare naturally, closer to natural materials color.But at present it is not yet found that people is using Jasmine flower residue as raw material
Natural pigment has certain nutrition and pharmacological action, coloring certainly however is favored by people because it is safe and reliable.
Natural red colouring matter is divided into fat-soluble natural red colouring matter and water-soluble natural haematochrome, and fat-soluble natural red colouring matter is due to molten in water
Solution degree is poor, and dispersion is uneven, thus application is restricted.Water-soluble natural haematochrome is present in plant cell liquor, due to
It is uniformly dispersed in water, colours nature, is highly-safe, there are also certain nutritive value or pharmacological actions for some, in modern food work
It is just gradually taken seriously in industry development.
Currently, the extracting method to water-soluble natural haematochrome mainly uses extraction, i.e., by mature dry fruit
After pericarp crushes, coarse powder is extracted with organic solvent, then leaching liquor is concentrated, dries to obtain haematochrome solid product, there are commonly
Solvent has acetone, ethyl alcohol, ether, chloroform etc..The product yield that this technique obtains is not high, and product purity is poor, later period purification
Difficulty, and solvent recovery is costly, the production cycle is long.
Summary of the invention
Aiming at the shortcomings in the prior art, the purpose of the present invention is to provide one kind extracts haematochrome from Jasmine flower residue
Method.

High-temperature sterilization is carried out again, sets sterilising temp range as 120-130 DEG C, pressure is 0.2~0.3MPa, and sterilizing duration range is
30-40 minutes；Jasmine flower residue is placed in water and impregnate 1-24 hours, its water content is made to reach 30-50%；Vacuum is dry
Jasmine flower residue after dry is crushed to 400 mesh or more in super-micro wall-broken grinder；Again to smashed Jasmine flower residue powder
In end, the ethyl alcohol of Jasmine 1.1-1.5 times of residue powder weight of flower is added, the concentration of the ethyl alcohol is 40-50%, then is passed through
Ultrasonic continuous stream biomixer, supersonic frequency 15-40KHz, power 1000-3000W, flow is suspension per hour
15Kg, obtained broken Jasmine flower residue powder suspension；
Step (2) preparation Jasmine flower residue extracting solution simultaneously filters；
After the evaporation of step (3) filtrate, resulting residue is the haematochrome extracted from Jasmine flower residue.
Step (2) adds 95% ethyl alcohol of food grade in gained jasmine pollen suspension in step (1), makes ethyl alcohol total weight
Jasmine is extracted again for Jasmine weight 15, pot for solvent extraction is closed and with stirring, and extraction temperature is 65-70 DEG C, when extraction
Between be 6-8h, Jasmine extract is obtained by filtration by 300-400 mesh.
Above-mentioned Jasmine alcohol extract is concentrated using vacuum suction method in step (3), and the temperature of vacuum suction concentration is 50-60
DEG C, time 2-4h, the adsorbent of vacuum suction concentration is active carbon or non-polar macroporous resin, and weight is former Jasmine weight
1-2 times of amount, using the high volatile component extracted out when adsorbent Adsorption Concentration with gaseous state ethyl alcohol, after gaseous state ethyl alcohol is then adsorbed agent
The cool trap in face recycles, and the group of vacuum concentration is divided into Jasmine medicinal extract；Use supercritical CO2Extractive technique is to being adsorbed with Jasmine
The adsorbent of high volatile component extracts, and extraction kettle pressure is 30-40Mpa, temperature is 20-25 DEG C, and separating still pressure is 8-
10Mpa, temperature are 50-60 DEG C, flow 90-100L/hr, obtain sticky paste haematochrome.
