| Œsing Natural Dyes from plants in Producing Colored Paste

|  i.|

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. 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 bayabas leaves, taro leaves and carrots were tested as coloring fir this paste. We can also use other coloring from plants by researching and do further study to improve the quality of this colored paste.

First, you must prepare all the ingredients. Then, after preparing, extract the color from the plants. You will extract the color pigment of taro leaves and bayabas leaves by sleeping it into half cup of hot water in two separate bowls. In the case of carrots you will cut it in small pieces using the knife, but be very careful while doing this, after cutting it in smaller pieces, you will crush the carrots using mortar and pestle then put it also in a separate bowl with hot water in it. After getting the color pigment you will put the three different natural dyes in the casseroles, then you will put it in a stove, while heating, you will put 3 tease spoons of starch and 2 tease spoons of alum. Stir until it becomes sticky. If it is sticky enough remove the casserole in the stove and wait for it to cool. If it is already cooled, you can transfer it in a container.

Our findings in our experiment, all of the colored pastes were effective in sticking.

|    Œsing Natural Dyes from plants in Producing Colored Paste is our investigatory project to make natural colored paste from plants that are non-toxic. This experiment will help us to recycle and to avoid spending too much money from buying expensive synthetic colors. 

|’ ’    We base or conceptualized our investigatory project from the High School students in other school in Manila. They perform this experiment with a huge success because of their patience and a keen-observant.

Procedure ÷| First, you must prepare all the ingredients. Then, after preparing, extract the color from the plants. You will extract the color pigment of taro leaves and bayabas leaves by sleeping it into half cup of hot water in two separate bowls. In the case of carrots you will cut it in small pieces using the knife, but be very careful while doing this, after cutting it in smaller pieces, you will crush the carrots using mortar and pestle then put it also in a separate bowl with hot water in it.

Stir until it becomes sticky. If it is sticky enough remove the casserole in the stove and wait for it to cool. If it is already cooled, you can transfer it in a container.



|’    ÷| We·d make sure that our products are sticky and effective enough to use as natural glue for the objects that might be using it.

×|3    After this experiment had been done, we came up with these conclusions: 1.| We can produce colored pastes from carrots, bayabas leaves and taro leaves. 2.| The produced pastes were safe and toxic free. 3.| The tawas or alum is a best preservative for the colored paste.

| ’    Œse other plants, fruits, or vegetables for producing other colored pastes, test other preservative to lengthen the life of the colored paste and do further study to improve the quality of the colored paste.
