Embodiment 1
[0033] A kind of preparation method of the modified starch that can replace gelatin, comprises the steps:
[0034] 1) The specific rice variety "Zhefu 201" starch with high amylose and soft gel consistency was selected as the raw material, and 3.0 g of the specific rice starch was taken to measure the amylose content and gel consistency of the rice starch, and the result was that the amylose content was 27.3%. , with a gel consistency of 89 mm, this rice starch can form a soft and solidified gel.
[0035] 2) Hydroxypropyl rice starch was prepared by chemical method of adding hydroxypropyl group, the adopted process parameters were: rice starch milk concentration 50% (m / m), propylene oxide 10wt%, reaction temperature 45°C, sodium hydroxide 1.2 wt%, sodium sulfate 15wt%, reaction time 20h.
[0036] 3) Prepare pre-gelatinized hydroxypropyl rice starch by heating physical method, the adopted process parameters are: gelatinization temperature is 95°C, gelatinization time is 2.5h, ...
Embodiment 2
[0039] The application of modified starch in preparing hollow capsules comprises the steps:
[0040] 1) Select modified starch as the coagulant, and the dosage is 500g / L;
[0041] 2) Add 1L of cold water to soak for 3 hours, stir once every 15 minutes until the homogenate is saturated;
[0042] 3) heating the starch and water homogenate to 80°C for gelatinization, adding 0.1wt% plasticizer, and stirring evenly;
[0043] 4) Stand at 80°C for 2 hours, pressurize to remove air bubbles;
[0044] 5) The colloid is cooled to a dipping temperature of 50°C, and poured into the insulation tank for dipping;
[0045] 6) drying to make hollow capsules with a moisture content of 12%.
