The invention discloses a kind of preparation methods of ellagic acid-PVP food fresh keeping solid dispersions, polyvinylpyrrolidone (PVP) is under hot ethanol dissolved state, molecule crimps chain and opens, ellagic acid in the curling chain of grain refinement and entrance PVP, carries out rotary evaporation processing removal solvent again and obtains ellagic acid-PVP solid dispersions under ultrasonication after ultrasonic treatment.The property that ellagic acid-PVP solid dispersions retain ellagic acid prevents the crystal accumulation of ellagic acid to grow up while stabilization, improves the solubility of ellagic acid, has broad application prospects on preservation of fishery.The PVP of different average molecular weight has different caking property, may be used to prepare solid dispersions.
Description
Technical field
The present invention relates to a kind of safety suitable for preservation of fishery, effective ellagic acid-PVP food fresh keeping solids point
The preparation method of granular media, the ellagic acid-PVP solid dispersions being prepared can be used for the fresh-keeping of fish.
Background technique
Preservation of fishery is exactly that the means such as Applied Physics, chemistry and biology handle it, to keep or protect as far as possible
Hold its original freshness.Currently, being applied to the preservation technology of aquatic products has low temperature, chemistry, irradiation, controlled atmosphere and biological preservation
Deng.Wherein, the most universal using antistaling agent and low in cost, it is easy to spread.In recent years, with the raising of people's environmental consciousness
With the development of preservation technology, the safety of fresh chemically gradually causes the worry of people, some biological preservations with Nantural non-toxic
Agent is common concern of the Preservation Treatment technology of raw material progress by people, and starts processing, the storage, fortune applied to aquatic products
In defeated and process of consumption.
Ellagic acid is the dimerization derivative of gallic acid, is a kind of polyphenol dilactone, ellagic acid content in raw-food material
Abundant, the content in the nuts such as the mushy fruits such as raspberry, blueberry and ginkgo, hickory nut is all very high, meanwhile, in the inedible of food
In part, the content such as ellagic acid in granatum, pomegranate seed, grape pip is also very high, the content of ellagic acid in granatum hydrolyzate
It is 12%.Ellagic acid can inhibit " pernicious " hormone secretion related with type II diabetes, and human immunodeficiency virus is inhibited to inhale
Attached, its antioxidant activity is 50 times of vitamin E, but the crystal structure of ellagic acid keeps its solubility in water very low,
Only 0.026mg/ml, the bioavilability that low solubility directly results in ellagic acid is low, and inoxidizability is difficult to play.
Solid dispersions refer to a kind of solid shape for dispersing hydrophilic carrier matrix for the substance of poorly water-soluble and being formed
The decentralized system of formula, the release conditions of active material are determined by polymer in decentralized system.Under dissolved state, polymer molecule
Chain expansion, active material enter the dispersion of formation molecular level in the curling chain of carrier, and intermolecular interaction generates hydrogen
Key or mating reaction inhibitory activity substance nucleus generate and growth is to achieve the purpose that improve solubility.Solid dispersions have
The advantages of production method is simply various, low manufacture cost.
Summary of the invention
It is an object of the invention to strong ellagic acid inoxidizability aiming at the problem that poorly water-soluble, a kind of ellagic acid-is proposed
The preparation method of PVP solid dispersions food preservative inhibits the aggregation and growth of ellagic acid crystal, makes ellagic acid in aqueous solution
In be easier to scatter, increase the solubility of ellagic acid, expand application of the ellagic acid as antistaling agent in food, especially exist
Application in the high aquatic products of surface moisture content, pushes the development of field of food preservation.
The purpose of the present invention is achieved through the following technical solutions: a kind of ellagic acid-PVP food fresh keeping solid dispersion
The preparation method of body, includes the following steps:
(1) by mass ratio be 1:(3~5) ellagic acid and PVP be completely dissolved in 60 DEG C of dehydrated alcohol；
(2) ultrasound treatment step (1) 0.5~1h of acquired solution；
(3) rotary evaporation removes vehicle of ethanol, scrapes the solid of revolving bottle inner wall, is put into baking oven and balances drying；
(4) pale yellow powder obtained is ellagic acid-PVP solid dispersions.
Further, ellagic acid is first crossed into 80~100 meshes before being dissolved in 60 DEG C of dehydrated alcohol in the step (1).
Further, in the step (3), the revolving speed of the rotary evaporation is 50~80r/min, and temperature is 50~70
Degree.
Further, balancing the dry time is 8~12h.
Further, balance is dry uses mortar milled solids, after 80~100 meshes.
Compared with prior art, the beneficial effects of the present invention are: the present invention uses water-solubility carrier PVP in conjunction with ellagic acid
The method for preparing solid dispersions prevents the aggregation and growth of ellagic acid crystal, remains the inoxidizability of ellagic acid, improve
The water solubility of ellagic acid can rest on food surface for more time, can effectively extend Food Shelf-life, suitable for aquatic products
Preservation Treatment.
Detailed description of the invention
Figure 1A is that the SEM of ellagic acid crystal schemes；Figure 1B is the ellagic acid-PVP solid dispersions that embodiment 1 is prepared
SEM figure.
Specific embodiment mode
Present invention will be further explained below with reference to specific examples.
Embodiment 1:
1, ellagic acid crosses 80 mesh 3-5 times, accurately weighs 1g ellagic acid and 3g PVPk30, it is completely dissolved under stirring
The hot dehydrated alcohol of 80mL60 DEG C of water bath processing.
2, ultrasound treatment step (1) acquired solution 0.5h.
3, rotary evaporation removes vehicle of ethanol, scrapes the solid of revolving bottle inner wall, is put into baking oven and balances dry 12h.
4,80 meshes are crossed after mortar milled solids, obtained pale yellow powder is ellagic acid-PVP solid dispersions, dry
It saves.
Ellagic acid therein can be extracted from granatum.
Identify that ellagic acid and PVP are complexed successfully through infrared spectroscopy, ultraviolet spectra.The dissolution of ellagic acid in solid dispersions
Degree is increased to 0.4129mg/mL, the experiment proved that, anti-oxidant being enhanced of ellagic acid-PVP solid dispersions.Using 0.3g/
100mL ellagic acid-PVP solid dispersions handle refrigeration hairtail, compared to conventional preservation method, can extend Larimichthys crocea
2~3d of shelf life.A is the SEM image of ellagic acid in Fig. 1, and B is the SEM image of solid dispersions, as seen from the figure ellagic acid
Entirely different with the surface texture of solid dispersions, ellagic acid exists with crystal form, and solid dispersions are deposited with unformed state
There are many irregular holes not of uniform size, when being that coprecipitation prepares solid dispersions, second on, the surface of solid dispersions
Caused by the evaporation of alcohol, the presence of hole increases the surface area of solid dispersions, so that ellagic acid is easier to dissolve out, ellagic acid
Crystal is dispersed in water-solubility carrier, and the presence of water-solubility carrier inhibits the aggregation and growth of ellagic acid crystal, and SEM image is aobvious
Show that the crystallinity of ellagic acid reduces.
Wherein k30 is more common in PVP, and the PVP of different average molecular weight has different caking property, may be used to prepare
Solid dispersions.
