Description
Technical field
The invention belongs to field of biotechnology, specifically, being related to a kind of catechin microcapsule preparation method.
Background technique
Currently, plant extract industry receives more and more attention, and research finds that effective component has human body in tealeaves
Important health-care effect, catechin are that most important ingredient plays very important effect in tealeaves, and catechin is as a kind of day
Right antioxidant and free radical scavenger, have been widely used for the multiple fields such as food, medicine and chemical industry, but catechin
Stability is poor, is easy to be influenced by many factors such as oxygen, temperature, moisture, ultraviolet lights, therefore the activity for the catechin that adequately protects
It is of crucial importance for developing and utilizing catechin.
In view of this present invention is specifically proposed.
Summary of the invention
The technical problem to be solved in the present invention is that overcoming the deficiencies of the prior art and provide a kind of catechin microcapsule preparation
Method, in order to solve the above technical problems, the present invention is using the basic conception of technical solution:
A kind of catechin microcapsule preparation method, comprising the following steps:
Step 1, tea extract is passed through into column chromatography for separation, obtains the catechin solution as core material after condensing crystallizing；
Step 2, Arabic gum, cycloheptaamylose, gelatin 15:10:1 in mass ratio are matched, obtains wall material；
Step 3, wall material is added in catechin solution, is configured to the solution that material concentration is 20%, be uniformly mixed simultaneously
It carries out high-pressure homogeneous, obtains catechin emulsion；
Step 4, catechin emulsion obtains catechin microcapsule by drying.
Further, the pressure of homogeneous is 30MP in the step 3.
Further, core material and the mass ratio of wall material are 1:2 in the step 3.
Further, catechin emulsion is dried with spray drying unit in the step 4, controls inlet air temperature
160-180 DEG C, 70-90 DEG C of leaving air temp.
After adopting the above technical scheme, the present invention has the advantages that compared with prior art.
The present invention, as mixing wall material, is mixed using arabinose, cycloheptaamylose and gelatin with catechin solution
Homogeneous, being spray-dried obtained microcapsule product can be good at retaining catechin activity, and preparation efficiency is high, stability is good,
Antioxidant activity is strong, and manufacture craft is simple, and production cost is low, and the application range for expanding catechin is of great significance.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below to the technical side in embodiment
Case is clearly and completely described, and the following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..If not
It refers in particular to, all parts, percentage are unit of weight.
Embodiment 1
A kind of catechin microcapsule preparation method, comprising the following steps:
Step 1, tea extract is passed through column chromatography for separation by the preparation of catechin, and it is molten to obtain catechin after condensing crystallizing
Liquid, catechin solution is as core material；
Step 2, the composition proportion of wall material, Arabic gum, cycloheptaamylose, gelatin are 15:10:1 progress according to mass ratio
Proportion, obtains wall material；
Step 3, wall material is added in catechin solution, is configured to material concentration according to core material and wall material ratio 1:2
20% solution is uniformly mixed, and progress is high-pressure homogeneous, and homogenization pressure 30MP obtains catechin emulsion；
Step 4, it is spray-dried, catechin emulsion is dried by being spray-dried unit, controls inlet air temperature 160-
180 DEG C, 70-90 DEG C of leaving air temp, catechin microcapsule is obtained after dry, collects product, packaging, storage.
The present invention, as mixing wall material, is mixed using arabinose, cycloheptaamylose and gelatin with catechin solution
Homogeneous, being spray-dried obtained microcapsule product can be good at retaining catechin activity, and preparation efficiency is high, stability is good,
Antioxidant activity is strong, and manufacture craft is simple, and production cost is low, and the application range for expanding catechin is of great significance.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this patent
Member without departing from the scope of the present invention, when the technology contents using above-mentioned prompt make it is a little change or be modified to
The equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, it is right according to the technical essence of the invention
Any simple modification, equivalent change and modification made by above embodiments, in the range of still falling within the present invention program.
