Embodiment Construction

[0025] Put 40-50g of corn flour in a conical flask, add 3-5g of α-amylase to the conical flask and add sodium dihydrogen phosphate-disodium hydrogen phosphate buffer solution with a pH value of 7, and set the volume to 100-110mL , then add 8-10mL of sodium hypochlorite solution with a mass fraction of 0.1% to the Erlenmeyer flask, place the Erlenmeyer flask in a shaker, heat it in a water bath to 42-45°C, and oscillate at a speed of 135-140r / min. After reacting for 3 to 4 days, add 10 to 12 mL of sodium hydroxide solution with a mass fraction of 40% to the Erlenmeyer flask to terminate the reaction to obtain a starch enzymatic hydrolysis solution;

[0026]Put the above starch enzymatic hydrolysis solution in an oven, heat up to 60-70°C, dry for 8-9 hours to obtain enzymatic corn flour, weigh 20-25g of enzymatic corn flour and add it to a three-necked flask with a thermometer and a nitrogen conduit In the three-necked flask, add 100-110mL distilled water, heat the three-necked ...

Abstract

The invention belongs to the technical field of medical material preparation, and particularly relates to a preparation method of water-retaining antioxidant starch based capsules. According to the preparation method, corn flour is taken as a raw material, acting force of hydrogen bond consisting of water-absorbing groups such as hydroxyl and the like exposed by the corn starch base after water absorption is larger, water retaining after water absorption is facilitated, calcium chloride doped into the starch capsules can permeate into a space network structure of grafted corn flour, water retaining capacity of the starch based capsules can be improved, so that the starch based capsules keep high moisture content, moisture retention performance is improved, and flexibility of the capsules is maintained; soybean isolate protein is dispersed to loose porous sodium alginate gel, after being oxidized by oxidizing substances or under illumination, the soybean isolate protein is decomposed into amino acid micromolecules to enter sodium alginate gel micropores, porosity of a wall material is reduced, and oxygen barrier property is improved; the starch based capsules imbibe a lycopene extracting solution, and filling substances of the capsules are prevented from being subjected to an oxidizing reaction, so that the antioxidative purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of preparation of medical materials, and in particular relates to a method for preparing water-retaining and anti-oxidation starch-based capsules. Background technique [0002] Capsules are widely used in the pharmaceutical and food processing industries as a protective wrapping material. According to the application requirements of the capsule, the capsule material needs to have certain water solubility and appropriate mechanical strength so that it can dissolve and release the contents in water, and at the same time maintain the original shape without damage when subjected to external force. [0003] Gelatin is the traditional material for making capsules. It has high mechanical strength, good toughness, and can be dissolved in water above 30°C. It is still the most widely used capsule material. But gelatin capsule itself has many disadvantages, such as: it is easy to breed microorganisms, and it is fragi...
