Embodiment 1

[0035] Please refer to figure 1 as shown, figure 1 The process flow chart prepared for soluble starch of the present invention comprises the following steps:

[0036] Step 1: Preparation of raw and auxiliary materials: heat purified water twice the mass of the starch raw material to 30-40°C, add concentrated hydrochloric acid solution 6.0-10.5% of the mass of the starch raw material, stir to make a hot hydrochloric acid solution, and set aside; the starch raw material Add 5-20°C low-temperature purified water of 1 times the mass of the starch raw material, stir to make a starch suspension, and set aside;

[0037] Step 2: Spray the starch suspension into the hot hydrochloric acid solution in the form of mist, and stir to form a mixed solution;

[0038] Step 3: Stir the mixed solution continuously, gradually and slowly heat the mixed solution to 45-65° C., and perform a hydrolysis reaction at the above-mentioned 45-65° C. for 7-24 hours to obtain a hydrolysis solution;

[003...

Embodiment 2

[0049] The optimization of the key technical parameters for the preparation of soluble starch in Example 1 is specifically described below through specific tests. In the preparation process of soluble starch, the polymer of soluble starch product is used as the reference standard, and the solubility of soluble starch and the sensitivity test to iodine are optimized.

[0050] The testing method for the degree of polymerization of soluble starch is: Somogyi colorimetric method, the principle of which is: soluble starch has exposed reducing ends, which can show certain reducing properties. In an alkaline environment, complexed Cu 2+ Can oxidize soluble starch to the corresponding acid, Cu 2+ is reduced to Cu + , form cuprous oxide precipitation; cuprous oxide can react with arsenomolybdic acid reagent to generate blue substance, the depth of its color is proportional to the concentration of reducing sugar, and has the maximum absorption at 560nm, the content of reducing sugar c...

Embodiment 3

[0107] Now in combination with the contents of Example 1 and Example 2, 3 batches (9 groups in total) of soluble starch were prepared. The starch raw materials produced by the 4 groups of pilot plants were corn starch, sweet potato starch, potato starch and kudzu root starch purchased from Xi'an Guowei Starch Co., Ltd. for testing. The equipment used in production includes: CT-C-II hot air circulation oven, SXG-5 rotary flash dryer, Kx1000 stainless steel rotary vibrating screen, GFSJ-32 high-efficiency pulverizer, improved 2000L with spray function The enamel reaction kettle, atomizing nozzle, centrifuge, several mixing tanks, reaction tank with interlayer, etc.

[0108] 1. One batch of pilot production, including 3 groups of parallel tests, 1 to 3 groups:

[0109] Step 1: Preparation of raw and auxiliary materials: add 200kg of cornstarch to 200L of 5-20°C low-temperature purified water in 1# mixing tank, stir to make cornstarch suspension, and set aside; add 400L of cornst...

Abstract

The invention provides a preparation technology of soluble starch. The preparation technology comprises the following steps: 1, preparing raw materials and auxiliary materials: preparing a hot hydrochloric acid solution and a starch suspension; 2, spraying the starch suspension into a hot hydrochloric acid solution in the form of fog drops, and performing stirring to form a mixed solution; 3, continuously stirring the mixed solution, heating the mixing solution, and continuously stirring the mixed solution at the raised temperature to carry out hydrolysis reaction in order to obtain a hydrolyzed solution; 4, filtering the hydrolyzed solution to obtain crude soluble starch; 5, adding low-temperature purified water or a sodium bicarbonate solution with a temperature of 5-10 DEG C into the crude soluble starch to wash the crude soluble starch with a small amount for multiple times until the obtained wash solution is neutral in order to obtain wet soluble starch; and step 6, drying, crushing and sieving the wet soluble starch to prepare the finished soluble starch. The soluble starch prepared in the invention has the advantages of good solubility, stable chemical properties, small difference among the polymerization degrees of all batches of soluble starch, and stable quality.

Description

technical field [0001] The invention relates to the technical field of starch preparation, in particular to a preparation process of soluble starch. Background technique [0002] The molecular formula of starch is (C 6 h 10 o 5 ) n , can be regarded as a high polymer of glucose. It is the most abundant natural polysaccharide polymer in nature. It is mainly extracted from starchy substances such as wheat, corn, sweet potato, and kudzu root. It is a renewable plant resource. There are two types of common starches: amylose and amylopectin. [0003] At present, pharmaceutical excipients are mainly composed of ordinary starch and dextrin. The solubility and disintegration of ordinary starch are not high, so it can only be used to make oral tablets and oral granules, and cannot be used to prepare buccal tablets; while dextrin will affect the determination of drug content, and because it is easy to absorb moisture, it will cause high viscosity Not easy plasmids. Ordinary sta...
