PROBLEMS
1.Can we produce colored paste out of cassava starch, water, alum and natural
dyes from plants like annatto seeds, carrots and roots of turmeric?
2.
Is the proposed paste safe to use?
3.
What is the best preservative that can be used in the colored paste?
TITLE:
COLORED PASTE OUT OF NATURAL DYES
ABSTRACT
Starch
may be further processed into such products as dextrin.
Starch glue is the general name for
adhesives made from wheat starch, potato starch, or cassava starch modified
with acids, alkalies, or oxidizing agents, it has poor resistance to moisture.
Commercial is obtained
from the starch of tapioca, maize and sweet potatoes. The halogen elements
(fluorine, chlorine, bromine, iodine, and astatine) also serve as oxidizing
agents. When chloride combines with sodium chloride or common salt, the sodium
atoms give up electron to the chloride atoms. A salt is derived from an acid
when one or more hydrogen atoms of the acid are replaced by one or more metal
ions positively charged radicals. Alkalies are usually salts or hydroxide of
sodium potassium, lithium or ammonia.
Alumina is used to
make abrasive and high-temperature refractions, ceramics and glass. Heated
alumina has porous structures that easily absorb moisture and vapors. Alumina compounds produce alums are used for
waterproofing fabrics and as the antiperspirant commercial deodorant.
First you must prepare all the materials
needed. After preparing, extract the coloring. If you will use carrots, extract
it by shredding and if roots of turmeric will be used as coloring, grind it in
the mortar and pestel then cover with half cup of hot water. And if you will
use Annatto seeds, extract it by covering with half cup of hot water. After extracting separate the dye from the
solid particles by pouring it to the strainer and add 2 teaspoon of alum into
the coloring in a bowl then add 3 teaspoon of cassava starch.
Heat the casserole in the stove and pour the
solution, if the casserole is already hot, 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 not hot anymore, you can transfer it in the container.
Conclusion
After the study had been done, the
researchers had these following conclusions. We can produce a colored paste out
of natural dyes from Annatto seeds, carrots and roots of turmeric. The produced
paste is safe to use since it does not contain any toxic chemicals because it came from plants. The
tawas or alum is the best preservative for colored paste.
NOTE:
I WOULD LIKE TO THANK THE OWNER.
ANOTHER NOTE:
I'VE CHANGE THE INGREDIENTS, THE RESULTS AND SOME PHRASE IN INTRODUCTION ETC.!!!!
