ATAS, DIANA JOYCE P., CATA, FLORAMIE LYNN P., Utilization of Dragon Fruit (Hylocereus undatus 13'ritto11 and Rose) Pseudostem and Fruit Extract in the Production of Bath Soap by Cold Process. Research Study (General Science Curriculum). Science High School, College of Education, Cavite State University, Indang, Cavite. March 2010. Adviser: Dr. Teddy F. Tepora.
A study entitled, "Utilization of Dragon Fruit (Hylocereus undatu.s' Breton and Rose) Pseudostem and Fruit Extract in the Production of Bath Soap by Cold Process' was conducted at Trece Martires City, Cavite from August 2009 until February 2010. Generally, the objective of the study was to assess the possibility of producing bath soap out of dragon fruit pseudostem and fruit extract. Specifically, the study aimed to (1) determine the color, odor, texture, consistency, mildness, and lather of bath soap produced out of dragon fruit pseudostem and fruit extract; (2) determine the level of general acceptability of bath soap produced out of dragon fruit pseudostem and fruit extract; ( ) compare the differences of the bath soap produced out of the pseudostem extract with that of the fruit extract in terms of color, odor, texture, consistency, mildness, and lather. The study focused in the evaluation of the bath soaps produced out of dragon fruit pseudostem and fruit extract. There were 2 treatments used: Treatment - dragon fruit extract; Treatment 2 - dragon fruit pseudostem extract.
Data gathered from the sensory evaluation were subjected to T-test for comparison. Ten laboratory panelists were carefully selected to test the produced cold processed soap. Another one hundred respondents were selected for general acceptability testing. The judges evaluated the two treatments at the same time. The assumption of normality of population was not satisfied by the data. The level of measurement was ordinal. Results of consumer acceptability were interpreted using frequency and percentage distribution. The study revealed that the bath soap could be produced both from the dragon fruit pseudostem and fruit.
The result of sensory evaluation of the laboratory panelists had shown that the consistency of the produced soap was the only attribute that significantly differs from both soaps. The rest of the attributes such as odor, texture, hardness, color, lather and mildness had revealed no significant difference between the two treatments. The bath soap made from the dragon fruit pseudostem extract was more acceptable over the bath soap from the dragon fruit extract from the consumer's point of view.
