The collected best enzyme fractions were selected for the biosoftening of banana pseudostem fiber. The banana pseudostem fiber was treated with crude enzymes at the time duration of 2, 4, 24, and 48 h. After the treatment, the treated and untreated fibers were evaluated for the mechanical properties and chemical constituent’s analysis. The results revealed that the chemical contents were high during 2- and 4-h-treated fibers. After that, chemical constituents were reduced due to the removal of debris by the action of enzymes. The mechanical properties such as breaking load, breaking extension, tenacity, and diameter of fiber were best in the fibers treated for 2 and 4 h. After 4 h due to the removal of chemical constituents the breaking load and tenacity, diameter will be reduced. <a href="https://www.sciencedirect.com/topics/engineering/scanning-electron-microscope" class="topic-link" style="margin: 0px; padding: 0px; background-color: rgba(0, 0, 0, 0); word-break: break-word; text-decoration: underline 1px rgb(31, 31, 31); color: rgb(31, 31, 31); text-underline-offset: 1px;">SEM</a> results proved that the fiber treated at 4th h showed smooth and softened fiber.</span></span></div></div><div id="abs0015" style="margin: 0px; padding: 0px; color: rgb(31, 31, 31); font-family: ElsevierGulliver, Georgia, "Times New Roman", Times, STIXGeneral, "Cambria Math", "Lucida Sans Unicode", "Microsoft Sans Serif", "Segoe UI Symbol", "Arial Unicode MS", serif, sans-serif; font-size: 16px;"><h3 class="u-h4 u-margin-m-top u-margin-xs-bottom" id="sect0020" style="margin-right: 0px; margin-left: 0px; padding: 0px; margin-top: 24px !important; margin-bottom: 8px !important; font-size: 20px !important; line-height: 30px !important;">Conclusion</h3><div class="u-margin-s-bottom" id="sp0045" style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; margin-bottom: 16px !important;">This study proved that the crude enzymes isolated from the <span style="margin: 0px; padding: 0px;"><a href="https://www.sciencedirect.com/topics/food-science/aspergillus" class="topic-link" style="margin: 0px; padding: 0px; background-color: rgba(0, 0, 0, 0); word-break: break-word; text-decoration: underline 1px rgb(31, 31, 31); color: rgb(31, 31, 31); text-underline-offset: 1px;">Aspergillus</a> niger</span> can be effectively soften and increase the quality of banana pseudostem fiber.</div></div>
