Abstract
The invention relates to a method for preparing a corn flavochrome ultra-microcapsulated clathrate. In the method, beta-cyclodextrin is taken as a wall material, and the corn flavochrome is taken as a core material. The method comprises the following steps: preparing certain concentration of corn flavochrome oil solution, adding the solution to ethanol, evenly mixing the solution and the ethanol, and then slowly adding an obtained mixture to beta-cyclodextrin saturated water solution, mixing, keeping standing, cooling and filtering mixture of the obtained mixture and the saturated water solution, and recovering and drying precipitate, thus obtaining the corn flavochrome ultra-microcapsule clathrate embedded with the beta-cyclodextrin. The method has the advantages of simple operating steps, low cost, simple equipment, single wall material component, raw materials being non-toxic and harmless raw materials of food, and high stability and better water solubility of the prepared corn flavochrome ultra-microcapsule clathrate. The method is especially suitable for application to industries such as food, medicine, health products and the like.
Description
Technical field
The present invention relates to the food additives field, relate in particular to the utilization molecular inclusion and prepare corn flavochrome ultra-microcapsulated clathrate.
Background technology
Corn yellow OB is a kind of natural food Agent, has stronger colorability.Except that using as food colour, also can be used as Nanutal food fresh-keeping agent, prevent the oxidation of lipid and vitamin in the food, keep flavour of food products and nutritional labeling wherein, prolongation food shelf life.In addition, corn yellow OB also has multiple physiological functions such as the tumour of inhibition, angiocardiopathy preventing, the change of the old macula lutea venereal disease of prevention, meets the developing direction of food additives " natural ", " nutrition ", " multi-functional ".In food industry, synthetic dyestuff such as that corn yellow OB replaces just gradually is lemon yellow, sunset yellow has vast market prospect.
Corn yellow OB is very sensitive to air and light, fades easily in air or under the irradiation of daylight.Secondly, corn yellow OB belongs to liposoluble substance, and the dissolubility in water is very poor, and this has limited its range of application to a certain extent.In addition, corn yellow OB is generally paste or aqueous, and transportation and use are all inconvenient.If corn yellow OB is prepared into ultra micro capsule inclusion compound, because the protective effect of wall material is arranged, can reduce the oxidation rate of corn yellow OB, avoid or reduce daylight, humidity and other external substance it is influenced, thus the stability of raising corn yellow OB.Simultaneously, corn yellow OB becomes pressed powder by behind the ultra micro capsule inclusion by liquid state or paste, easy to use, transportation and preserving.
The present invention adopts molecular inclusion to prepare corn flavochrome ultra-microcapsulated clathrate.Molecular inclusion is a kind of microencapsulation technology that occurs on the molecular level, and this technology device therefor is simple, with low cost, and products obtained therefrom is stable under the air drying state, and water-soluble better.It mainly utilizes the special molecular structure of beta-schardinger dextrin-, makes hydrophobic molecule pass through to form stable ultra micro capsule inclusion compound in the tubular structure of hydrogen bond, Van der Waals force and hydrophobic effect embedding beta-schardinger dextrin-molecule.Nontoxic, the easily biological-degradable of beta-schardinger dextrin-generates the glucose that can directly be utilized by human body after the hydrolysis, be widely used in food and the medical industry.
Summary of the invention
The object of the present invention is to provide a kind of water-soluble better, the Powdered corn flavochrome ultra-microcapsulated clathrate of stable in properties and preparation method thereof.
Summary of the invention
The present invention utilizes beta-schardinger dextrin-to make the wall material, and core is a corn yellow OB.Operating procedure: corn yellow OB is dissolved in the edible oil, be mixed with certain density corn yellow OB oil solution, add a certain amount of ethanol again, to be mixedly it is slowly joined in the beta-schardinger dextrin-saturated aqueous solution after evenly, stir at a certain temperature, make corn yellow OB by the embedding of beta-schardinger dextrin-molecule.Suction filtration reclaims and washing precipitate then, can obtain the corn flavochrome ultra-microcapsulated clathrate of beta-schardinger dextrin-embedding after the drying.
Detailed Description Of The Invention
Technical scheme of the present invention is: a kind of corn flavochrome ultra-microcapsulated clathrate of beta-schardinger dextrin-embedding, core are corn yellow OB, and the wall material is a beta-schardinger dextrin-, and described core and wall material mass ratio are 1: 10-30.
The preparation process of above-mentioned corn flavochrome ultra-microcapsulated clathrate is as follows:
(1) in the 60-70 ℃ of beta-schardinger dextrin-saturated aqueous solution of preparing down, is cooled to 50 ℃-35 ℃, heat preservation for standby use.
(2) corn yellow OB is dissolved in the edible oil at normal temperatures, is mixed with 0.1-0.6g/mL corn yellow OB oil solution.
(3) the corn yellow OB oil solution for preparing is dissolved in a certain amount of ethanol, treat dissolving fully after, it slowly is added drop-wise in the beta-schardinger dextrin-saturated solution for preparing, lucifuge constant temperature stirs 6-24h, places refrigeration 10-30h in the refrigerator.Wherein, the volume ratio of corn yellow OB oil solution and ethanol can be 0.5-3: 1.
(4) with the solution suction filtration after (3) described refrigeration, get sediment, can obtain corn flavochrome ultra-microcapsulated clathrate after the drying.
Edible oil in the abovementioned steps (2) can be soybean salad oil, peanut oil, tea-seed oil, palm wet goods.
Drying in the abovementioned steps (4) can adopt multiple dried forms such as oven for drying, vacuum drying, freeze drying.
The present invention utilizes the molecule embedding techniques to prepare the corn flavochrome ultra-microcapsulated clathrate powder, and operating procedure is simple, device therefor is simple, with low cost.The wall material component is single, need not add chemical substances such as emulsifying agent, curing agent.Used raw material all are to the nontoxic raw-food material of human body, do not have safety problem.
Corn yellow OB after the embedding is Powdered, and good stability is water-soluble good, is easy to preserve, transports and uses, and range of application obtains enlarging.
