Research Status and Prospect of Gum Arabic

Gum arabic is the general term for resins derived from gum trees grown in areas such as Arabia, Africa and Australia. Its application has been used for thousands of years. With the improvement of various requirements for food and other products and the continuous development of science and technology, the demand for gum arabic continues to increase in China, and there is gradually a shortage of markets in short supply, especially in the food industry.

1. Research status of gum arabic

Zhang Jianrong also researched a series of microcapsules under different process conditions by using acacia gum and gelatin as capsule materials, using acacia and gelatin as capsule materials. They can all form a film or capsule surrounding the sphere perfume, and showed that Gum Arabic has a good ability to maintain the aroma. And the research shows that gum arabic has good solubility. Within a certain range, its viscosity and concentration are positively correlated, not related to PH.

Wu Youzhi and others studied the use of sodium alginate wall material for encapsulation, the introduction of gum arabic, using the optimized optimal preparation process parameters to prepare a composite thin wall, and then to determine the sustained release ability, and finally with no added gum The thin-walled comparison of sustained-release performance. It shows that adding gum arabic in a single thin wall can affect the embedding effect of fragrance, but it can better suppress the release of fragrance. Its influence on embedding rate can reach 65% -74%, in order to optimize its preparation process, 0.4% -1.2% gum arabic can be added, and products with better performance can be prepared.

Shi Dian et al. Studied the use of gum arabic as an additive in the mixing and modification of corn starch to help improve the performance of starch slurry.

Liao Jin et al. Studied a mixed system of potato starch with different contents of Arabia, which is salt-tolerant and acid-tolerant, and gum arabic can significantly reduce the potato starch paste viscosity and improve the thermal stability of starch paste. During the cooling process, the starch viscosity increased significantly, and the degree of recovery increased slightly.

2. Outlook

With the increasing maturity of application technology and the continuous increase of application fields, the demand for gum arabic in China has also risen significantly, and its application in the food industry and other industries also has great potential. Therefore, we need to have a deeper understanding and understanding of the properties and functions of gum arabic. Through in-depth research on it, we should guide us to use gum arabic more reasonably and effectively, which is of great significance to China's scientific progress and economic construction.
