ABSTRACT
This study in Completely Randomized Design determined the quality of paper made from mango fruit fibers in terms of folding endurance., oil absorption, water retention, texture and market acceptability. This study also determined the significant difference in the quality of the paper products made from different mango fiber-pulp concentrations i.e., 25%-75% mango fiber-pulp, 50%-50% mango fiber-pulp, and 75%-25% mango fiber-pulp concentrations. Each treatment group underwent three (3) trials for each of quality test except that of texture and market acceptability tests which was subjected to panel judgment. In analyzing the data that was gathered from this study, the mean and standard deviation was used as descriptive statistical tool.
The results of this study showed that the mango fruit fiber was able to enhance the paper’s folding endurance; however, the paper’s texture is negatively affected as mango concentration is increased.
As for the oil absorption and water retention abilities of the paper products, a specific mango fiber-pulp concentration is required to attain the best results. There was no evident relationship between the amount of mango fiber and the enhancement of the said abilities. And in this study, it was the 25%-75% mango fiber-pulp concentration for the oil absorption, and the 50%-50% mango fiber-pulp concentration for the water retention.
As judged by a panel of experts in paper products and marketing, not all mango fiber-pulp concentrations produce paper products that are excellent in texture and commercially competent. And in terms of the five measures of quality of paper products made from mango fiber, there was no specific mango fiber-pulp concentration whose quality is very similar to that of the commercial handmade paper.
