Description
Technical field
The present invention relates to the technical field of seeweed polyphenol, and in particular to the preparation method of seeweed polyphenol extract.
Background technology
Seeweed polyphenol (algae polyphenols, AP) is the polyphenol compound general name extracted from seaweed, is
Has the secondary metabolite of seaweed, and seaweed protects itself from the active principle of adventive interference.Seeweed polyphenol conduct
The main source of sea-plant polyphenol, the land plant polyphenol such as its structure and tea polyphenols, apple polyphenol, Punica granatum L. polyphenol exist obvious
Difference, seeweed polyphenol basic structural unit are phloroglucins, and simply phloroglucin connection mode is different with quantity.Wherein in brown alga
Polyphenol content is compared with horn of plenty, and brown alga has the characteristics that distribution is wide, species is more, yield is high, so brown alga is that extraction separation is more
The excellent algae of phenol.
Seeweed polyphenol have it is antitumor, anti-oxidant, numerous physiological activity such as antibacterial, antiviral, not only there is very strong pharmacology
Activity, and brown algae polyphenols belong to less toxic chemical substance, edible safety.In October, 2017 major website orientation European Union assessment kelp
News of the brown algae polyphenols extract as the security of new resource food, it is food supplement to claim this new resource food work done in the manner of a certain author
For the normal adults of more than 12 years old, with people's multi-functional understanding many to polyphenol and the further depth of plant polyphenol research
Enter, can predict that seeweed polyphenol future will have wider array of market development prospect.
The research of current seeweed polyphenol is concentrated mainly on the preparation of the extracting method and high-purity polyphenol product of polyphenol
In improvement, such as Chinese patent CN201510529461.2；CN201710070691.6；CN2012105226792.7；
CN201610611275.8；CN201510648035.0, but these patents be only absorbed in the extraction process of polyphenol, extraction efficiency and
Product purity, and the unstability of polyphenol property is ignored, polyphenol is easily aoxidized, particularly easily rotten under light illumination, at the same time
Polyphenol contains multiple hydroxyls, easily forms hydrogen bond with water so that and, there is the characteristics of not easy to maintain in dried sample easy to absorb moisture,
And some techniques are complex or equipment requirement is higher, be not suitable for large-scale production.Meanwhile seeweed polyphenol is as exclusive
Sea-plant property polyphenol, its extract influence eating mouth feel, always there are the fishy smell of a degree of seaweed and the bitter taste of polyphenol
It, due to presence of the seeweed polyphenol there are content the problems such as relatively low, unstable oxidizable, mouthfeel is bad, limits seeweed polyphenol
Industrialized development, therefore there is an urgent need to develop the product that a kind of polyphenol content is high, property is stable, is easy to preserve and eats.
Microencapsulation technology is a kind of technology for using different wall materials to be embedded active material, and wall material has natural polymer
Sub- material and synthesis high molecular material, and apply the features such as natural macromolecular material is because of stabilization, nontoxic, good film-forming property it is more,
More commonly used natural macromolecular material has glue, polysaccharide, protein etc.., can by selecting different wall materials to carry out embedding treatment
Playing improves the stability of active material, changes its physical property, control release, isolation active ingredient, shielding taste and smell
Etc. a series of effects..
The content of the invention
It is an object of the invention to solve bad current seeweed polyphenol stability, the easy moisture absorption, mobility is bad and mouthfeel is owed
Good problem, there is provided a kind of microencapsulation seeweed polyphenol extract, extraction and separation process are combined with microencapsulation technology of preparing, are made micro-
Encapsulated seeweed polyphenol extract stability is good, being not easy the moisture absorption, mobility, good, mouthfeel is easy to receive.In addition the present invention also provides one
The preparation method of kind microencapsulation seeweed polyphenol extract, technique is simple, easily operated, and it is excellent that properties of product are made.
For achieving the above object, the present invention uses following technical scheme：
A kind of microencapsulation seeweed polyphenol extract, core are seeweed polyphenol extract, and wall material is that mass ratio is 1:3-5 Arabic gums

The macroreticular resin handled well on concentrate, is first eluted with pure water after the completion of absorption and removes polysaccharide, inorganic ions impurity, then use body
Product concentration 50-90% ethanol elutions obtain polyphenol eluent, elution speed 2-4BV/h, and eluent dosage is 3-5BV, and polyphenol elutes
Liquid is recovered under reduced pressure ethanol and obtains seeweed polyphenol extracting solution, and polyphenol content is more than 30% in this extracting solution；
The preparation of step (3), seeweed polyphenol microcapsules：By step（Two）In seeweed polyphenol extracting solution as core, with me
Primary glue and polysaccharide are wall material, and first wall material is dissolved in pure water, are made into the solution that concentration is 1-5%, then add seeweed polyphenol and carry
Take in liquid and stir evenly, it is 8%-12% to be concentrated under reduced pressure into solid content, and spray drying obtains microencapsulation seeweed polyphenol extract.
Wherein, the step（One）The high brown alga of middle seaweed, preferably polyphenol content, including kelp, kelp, sargassum fusifome, skirt
Band dish and its sporophyll etc..
The step（Two）Middle macroreticular resin is AB-8 or NKA-9 type macroreticular resins
The step（Three）Middle wall material and core mass ratio 1-3:1.
Using above-mentioned technique it is a technical advantage that the following aspects：
（1）By taking a variety of methods, the higher seeweed polyphenol extract of content is obtained（Polyphenol content is more than 30%）, such as choose
The high brown alga of polyphenol content is extracted for raw material, using the ethanol of various concentrations, using macroreticular resin further clean and pure
Change.
（2）By the extraction process of seeweed polyphenol with microcapsule preparation process rationally, be effectively combined, realize once
Property feed intake and can obtain the product of microencapsulation, technological process is simple, rationally, on the premise of equipment is not increased, shortens life
The flow of production. art and time, and it is easy to the production of large-scale.
（3）Pass through the technology of preparing of microcapsules so that stability, physical behavior and the mouthfeel of seeweed polyphenol product obtain
Improve, the fishy smell of seaweed and the bitter taste of polyphenol decrease in the product produced, while product has that stability is good, flowing
Property it is good and the characteristics of be not easy the moisture absorption, be conducive to holding and use and the increase bioavilability of product, so that it is more to expand seaweed
Application of the phenol in each field.
