The present study is aimed at investigating the properties of Cassava starch for the production of adhesives as a career opportunity in chemistry education. Method of starch extraction, characterization and adhesive production for quality assessment was performed. The results showed that adhesives produced with sodium hydroxide as a gelatinization enhancer has a maximum drying time of 8.60 minutes and had a stronger bond. The work concludes that the adhesive produced is of good quality and can lead to re-inventing chemistry education as a career opportunity. However, the Cassava adhesive met the basic requirement for adhesive use and application. At the end recommendations were made, among others increase employment opportunities, also diversify the economic base of farmers and there is need for reorientation and attitudinal change towards entrepreneurial job.
Cassava (Manihot esculenta Crantz) is an important food crop in many tropical countries in Africa, South America and Asia. However, in Thailand, this crop has been well recognized as more than a subsistence crop. It is important commercially as the raw material for a large and complex industrial system that has a significant impact to the country's economics. The roots of this crop contain high a starch content and approximately half of the total roots produced (20 million tons) are used for the starch industry. Cassava starch has many remarkable characteristics including high paste viscosity, high paste clarity and high freeze-thaw stability, which are advantageous to many industries. In particular, the native starch with high purity can be readily modified by physical, chemical and enzyme process to many diversified products to improve the starch functionality and, consequently, encourage more industrial application. This paper aims to describe the unique modification of cassava starch produced at the industrial level in Thailand with respect to technological aspect and product quality.
