Natural Dyes from Plants in Producing Colored Paste
Natural Dyes from Plants in Producing Colored Paste
Abstract:
Paste is a type of glue made from starch or dextrin, a starch product. This investigatory project shows that we can produce our own colored paste without spending much time and money and by performing simple steps. That’s why this Science Investigatory Project can help students save their money instead of spending it in buying expensive and commercialized colored glue. In addition, this colored paste can be an additional source of income. It’s not just affordable; it’s also safe and non-toxic because the ingredients used are starch, water, natural dyes from plants and alum. Alum is used as preservative to prolong the shelf-life of the paste. Natural dyes from plants like Annatto seeds, mayana and turmeric were tested as coloring for this paste. We can also use other coloring from plants by researching and do further study to improve the quality of this colored paste.
Introduction:
Background of the Study:
Nowadays our country has big problem about our economy. Everyone to solve it, but what do you think are the possible ways to prevent his crisis? I suggest that being practical is one of the solution to this problem. As students, we can be practical by using our knowledge instead of wasting our money. These projects do not need much time and money because we can make our own colored paste within a short period of time. The basic ingredients are water, alum, natural dye from plants and cassava starch. Starch glue is the general name for adhesives made from wheat, starch, potato starch, cornstarch or cassava starch modified with acids, alkalies or oxidizing agents. I used alum in this project to prolong the shelf life of the paste and also to let the paste not to be spoiled easily. The coloring that we used in this experiment is the seeds of Annatto (BIXA ORELLANA Linn). The seeds of the Annatto are used locally for coloring food. The coloring matter of the fruit, Annatto is employed
