The importance of starch and its application in daily life
Starch is an important organic compound and the main form of energy storage in many organisms. It is not only widely distributed in plants, but also an indispensable part of human daily diet. The application range of starch is very extensive, in addition to the food industry, many fields such as medicine, textiles, and papermaking cannot do without the application of starch. This article will introduce the structure and characteristics of starch, as well as its important applications in daily life.
Structure and characteristics of starch
Starch is a polysaccharide composed of many glucose units that pass through α- 1,4-glycosidic bonds and α- Formed by connecting 1,6-glycosidic bonds. It has two forms: amylose and amylopectin. Straight chain starch is formed by linear connections of glucose units, forming a helical structure that is insoluble in water. And branched starch is composed of linear starch and branched starch interwoven with each other, which has good water solubility.
The application of starch in the food industry
Starch plays a crucial role in the food industry. It can be used as a thickener, stabilizer, gelling agent, and emulsifier. For example, in baked goods, starch can increase the stickiness of the dough, improve the texture and taste of the product. In the production of cold drinks, starch can be used to prevent freezing and enhance the taste. In addition, starch is often used to make vermicelli, pastries, jelly, etc.
The application of starch in the pharmaceutical field
Starch also has important applications in the pharmaceutical field. For example, starch is commonly used as a filler in the preparation of tablets and capsules. It can increase the volume of the pill and make it easier to take. In addition, starch is often used as a matrix in the preparation of various ointments and injections to increase its stability and medication effectiveness.
The Application of Starch in Textile and Paper Industry
Starch is widely used in the textile industry in the sizing and dyeing processes of textiles. Starch can increase the consistency and strength of textiles, improve the uniformity and fixation of dyeing. In the papermaking industry, starch is also commonly used as an internal and surface treatment agent for paper, increasing its luster and strength.
Conclusion:
Starch is an important organic compound widely used in various fields of life. Its characteristics and functions make it play an important role in the food industry, pharmaceutical industry, textile and paper industry, etc. A deep understanding of the structure and application of starch can help better utilize its functions and promote its wider application in different fields
