Modified starch is used correctly

Modified starch is used correctly

Modified starch is a starch derivative widely used in food, pharmaceutical, papermaking, textile and other industries, due to its excellent physical and chemical properties and functionality, the correct use of modified starch in the production process is of great significance to improve product quality and performance. This article will detail the proper use of modified starch to help readers better apply this important starch derivative.

1. Selection of modified starch.

When selecting modified starch, it should be considered comprehensively according to the specific application needs and the nature of the starch. Different types of modified starch have different physicochemical properties and functions, so suitable modified starch varieties should be selected according to the desired product properties and processing requirements. At the same time, attention should be paid to choosing brands and manufacturers with stable quality and good reputation to ensure the quality and safety of modified starch.

2. Dissolution of modified starch.

Before using modified starch, it needs to be dissolved well. Since the solubility of modified starch is affected by factors such as temperature, stirring speed, and stirring time, it should be operated according to specific requirements. In general, modified starch is mixed with an appropriate amount of water and stirred continuously under heating conditions until it is completely dissolved. The stirring speed and time should be properly controlled, too fast or too slow will affect the dissolution effect of modified starch.

3. The amount of modified starch added.

The amount of modified starch added should be determined according to the specific application needs. In food processing, the addition of modified starch generally does not exceed 5% of the total amount of raw materials, while in the pharmaceutical and textile industries, the addition amount may be higher. When determining the amount of addition, the influence of modified starch on product performance should be fully considered, while paying attention to cost control.

Fourth, the use of modified starch.

1.Dry blending method: Modified starch is mixed with raw materials evenly and then processed. This method is suitable for occasions with large production volumes and low requirements for product performance.

2.Pregelatinization method: Mix the raw materials with an appropriate amount of water, heat and stir, then add modified starch gelatinization, and finally dry to obtain pregelatinized starch. Pregelatinized starch has good water solubility and stability, and is suitable for occasions that require rapid dissolution.

3.Emulsification method: the raw material is mixed with an appropriate amount of water, heated and stirred, then modified starch is added to gelatinize, and finally a stable water emulsion is formed through the action of emulsifier. The emulsification method is suitable for applications where stable aqueous emulsions or suspensions need to be prepared.

4.Spray drying method: the raw materials are mixed with an appropriate amount of water and heated and stirred, then modified starch is added to gelatinize, and finally the modified starch is obtained by spray drying. The modified starch prepared by spray drying method has good fluidity and dispersion, and is suitable for the occasion of preparing products with good fluidity.

5. Precautions.

1.Suitable modified starch varieties and addition amounts should be selected according to the specific application needs and processing requirements, and attention should be paid to cost control.

2.When using modified starch, attention should be paid to the control of operating conditions, such as temperature, stirring speed and time, etc., to ensure the dissolution effect of modified starch and product quality.

3.When using modified starch, attention should be paid to compatibility and compatibility with other raw materials to avoid adverse reactions or reduce product quality.

4.During storage and use, attention should be paid to preventing moisture, contamination and deterioration of modified starch to ensure the safety and quality of the product.
