Abstract

The invention relates to a method for extracting effective components of mulberry. The method comprises the steps of (1) washing mulberry for 2-3 times by clear water, draining water, then pulverizing the mulberry to obtain mulberry slurry, and freezing and storing at -2 DEG C for use; (2) unfreezing the frozen mulberry slurry in the step (1) and adding extracting solution into the frozen mulberry slurry to leach for 1-3 hours at the temperature condition of 50-70 DEG C, and then filtering the solution to obtain leach liquor and filter residue; (3) adding the extracting solution to the filter residue to leach for 1-3 hours at the temperature condition of 50-70 DEG C, and then filtering to obtain secondary leach liquor; and (4) merging twice leach liquor, putting the leach liquor into a rotary evaporator, evaporating and recovering the extracting solution, and drying the product in the evaporator under a vacuum condition to obtain mulberry red pigment. The extracting method disclosed by the invention is simple and convenient, and easy to operate; the extracting solution can be effectively recovered; and the resource is saved while the extracted mulberry red pigment is high in productivity, and the application value is also improved.

Description

A kind of extracting method of mulberry fruit effective constituent

Technical field

The present invention relates to a kind of extracting method, especially relate to a kind of extracting method of mulberry fruit effective constituent, belong to middle extractive technique field.

Background technology

Contain the compositions such as abundant activated protein, VITAMIN, amino acid, carotene, mineral substance, trans-resveratrol, anthocyanidin in the mulberry fruit, nutrition is 5～6 times of apple, be 4 times of grape, have multiple efficacies, be described as " the best health fruit of 21st century " by medical circle.Often eat mulberry fruit and can significantly improve body immunity, have and delay senility the effect of beautifying face and moistering lotion.

And the haematochrome in the mulberry fruit has in candy, jelly, haw jelly, fruit wine and beverage widely and to use, and this kind haematochrome is owing to be natural red colouring matter, security is good, tint permanence is high, water-soluble by force, and be of value to the absorption of human body.And the extracting method more complicated of traditional mulberry fruit effective constituent, and productivity ratio is lower.

Summary of the invention

For solving the deficiencies in the prior art, the object of the present invention is to provide the extracting method of the mulberry fruit effective constituent that a kind of method is simple, productive rate is high.

For achieving the above object, the present invention is achieved by the following technical solutions:

A kind of extracting method of mulberry fruit effective constituent is characterized in that, may further comprise the steps:

(1) get the raw materials ready: get mulberry fruit at first with after clear water washing 2-3 time, drain away the water, then mulberry fruit is pulverized, obtain the mulberry fruit slurries, and in-2 ℃ of lower freezing preservations, for subsequent use;

(2) lixiviate: the freezing mulberry fruit slurries of the described process of step (1) are thawed, and to wherein adding extracting solution, under 50-70 ℃ temperature condition, then lixiviate 1-3h, filters, and obtains vat liquor and filter residue;

(3) secondary lixiviate: add extracting solution in the described filter residue of step (2), under 50-70 ℃ temperature condition, then lixiviate 1-3h, filters and obtains the secondary vat liquor;

(4) drying: after step (2) and the described vat liquor merging of step (3), put in the rotatory evaporator, the extracting solution evaporation is reclaimed, product is dry under vacuum condition in the vaporizer, obtains mulberry fruit effective constituent.

Further, described extracting solution is at least a among water, 95% ethanol and the 0.1%HCl.

Be preferably, described extracting solution is the mixture of 95% ethanol and 0.1%HCl, and wherein, the volume ratio of described 95% ethanol and 0.1%HCl is 1:1.

In addition, the mass ratio of the mulberry fruit slurries described in the step (2) and extracting solution is 1:10-15.And the mass ratio of the filter residue described in the step (3) and extracting solution is 1:10-15.

The invention has the beneficial effects as follows: simple and convenient, the easy handling of extracting method of the present invention, extracting solution can efficient recovery, saved resource, and the mulberry fruit effective constituent (mulberry red pigment) of extracting, productive rate is very high, has improved its using value.
