This project entitled “Utilization of Red Bell Pepper (Capsicum Annum) Fruit Extract as
Watercolor Paint” was aimed to develop an alternative source of pigment for watercolor
paint out of locally available over-ripe red bell peppers which are abundant and are usually
put to waste when no longer appropriate for food consumption. The process involves
extracting of pigment/colorant from the red bell pepper through boiling/steaming,
blending, sieving and mixing with binding agents and solvents such as Gum Arabic,
Ethanol and vanilla extract. Another process involves air drying of red bell pepper pulp to
produce higher quality colorant. The use of red bell pepper in the study seeks to prove that
vegetables are indeed a source of colorants for inks/paints and natural colors and serve as
a useful alternative source of pigment. This innovation seeks to help watercolor
manufacturing industry lessen the cost of raw materials and save the cost of production.
The use of over-ripe red bell pepper in this study promotes the idea of recycling and
conversion from waste to by-product. The produced watercolor pigments were proven to
be useful and practical as an alternative pigment for creating this type of art material. The
acceptability performance of the produced watercolor was evaluated by a group of experts
in the field of printing and chemistry in terms of functionality, workability, aesthetics,
economy, and safety. Evaluators were composed of six (6) faculty, and nineteen (19)
students from the Graphic Arts and Printing Technology and Architecture students. The
mean ratings of the evaluation in the seven criteria are 3.9 for functionality, 4.1 for
aesthetic, 4 for workability, 4.1 for durability, 4.1 for the economy, 4.4 for safety and 3.9
for saleability. Safety was proven to have the highest rating in the innovation in processing
the produced colorant is found to be free from harmful chemicals, and the mixture exhibits
natural and unique quality, and the color is long lasting.This project entitled “Utilization of Red Bell Pepper (Capsicum Annum) Fruit Extract as
