Abstract
The invention relates to an extraction, separation and purification method of trehalose, in particular to a separation and purification method of trehalose by one-step. The method comprises the steps of: after extracting dry yeast by using water, adding a flocculating agent to adjust the pH value; and then filtering to obtain clear filtrate, and directly concentrating and crystallizing to obtain trehalose crystals. The method has simple separation and purification steps, convenience and feasibility, low cost and good effect, and provides conditions for the trehalose to be widely used in the fields of medicine, cosmetics, food preservation and the like.
Description
Technical field
The present invention relates to separation and purification trehalose technology from dry yeast.
Background technology
Have the trehalose of title of " sugar of life " nontoxic, human body is had no side effect, essential property is similar to other disaccharide.But himself has non-specific provide protection; can make organism behind the drying and dehydrating with extremely low and even stop metabolic form it is protected; in case environmental permission; organism can be brought back to life; but do not decrease living matter, so trehalose is widely used in aspects such as the drying preservation, medical science, health, beauty treatment of food.The interior method of producing trehalose of world wide mainly contains enzyme transforming process and extracts from barms at present.Domestic a company has adopted enzyme transforming process to produce trehalose, but it is subjected to starting material---the restriction of tapioca (flour) plantation; And traditional yeast extraction method purification procedures is many, causes production cost height, low, the valuable product of target product, has seriously limited the widespread use of trehalose.
Summary of the invention
The objective of the invention is to remedy the prior art above shortcomings, propose the technology of single stage method separation and purification trehalose, extraction process is simple, and is effective.
Technical scheme of the present invention is as follows:
The technology of single stage method separation and purification trehalose, utilize solvent under room temperature-80 ℃ from dry yeast by stirring by solid and liquid mass volume ratio 1: 100---1: 1 (g: mL) extract trehalose, add vitriol by extracting the amount that adds 5 grams among the aqueous trehalose 100ml then, by regulating the pH value to neutral, generate flocculation agent, filter promptly to get then and clarify aqueous trehalose, condensing crystal can get product.
Described solvent comprises the ethanolic soln of various concentration.
Can directly filter with flame filter press after forming flocculation agent, flocculation agent can directly get clear filtrate as filtration medium.
Regulate pH and can use all alkaloids.
The present invention can reduce purification procedures, only can reach the purifying purpose with i.e. filtration of a step, greatly reduces production cost, for the widespread use of trehalose provides condition.
Description of drawings
Fig. 1 adopts the white powder trehalose crystal pattern that obtains after the inventive method crystallization.
Embodiment
Below describe implementation process of the present invention and beyond thought many-sided positive effect of being brought in detail by specific embodiment; be intended to help the reader to understand better and understand essence of the present invention and the novelty place; but but practical range of the present invention is not constituted any qualification; in the instruction of this explanation with any modification and the change made under inspiring, all should belong to the protection domain of claims of the present invention for the personage who knows art technology to technical solution of the present invention.
Embodiment 1.
Get 80% the ethanolic soln that the 5g dry yeast adds 100ml, in 80 ℃ of scopes, stir and extracted 2 hours.Extracting solution is added 3g zinc sulfate,, filter with flame filter press to neutral with the sodium hydroxide adjust pH, the gained clear filtrate is the good aqueous trehalose of purifying.
Embodiment 2.

Embodiment 3.
Get 50% ethanolic soln that the 10g dry yeast adds 100ml, in 50 ℃ of scopes, stir and extracted 2 hours.Extracting solution is added 4g zinc sulfate,, filter with flame filter press to neutral with the sodium hydroxide adjust pH, the gained clear filtrate is the good aqueous trehalose of purifying.
Embodiment 4.
Get 70% ethanolic soln that the 3g dry yeast adds 100ml, in 60 ℃ of scopes, stir and extracted 2 hours.Extracting solution is added 6g zinc sulfate,, filter with flame filter press to neutral with the sodium hydroxide adjust pH, the gained clear filtrate is the good aqueous trehalose of purifying.
Embodiment 5.
Get 70% ethanolic soln that the 3g dry yeast adds 100ml, in 70 ℃ of scopes, stir and extracted 2 hours.Extracting solution is added 6g zinc sulfate,, filter with flame filter press to neutral with the sodium hydroxide adjust pH, the gained clear filtrate is the good aqueous trehalose of purifying.
Extract trehalose by aforesaid method, its extraction yield on average can reach 15g trehalose/100g dry yeast.Can obtain white powder trehalose crystal after the proper method crystallization, as shown in Figure 1.
