Abstract
The objective of this research was to study the effects of corn varieties, layers of corn husks, and fiber extraction methods on chemical compositions of corn husk fibers. Three corn varieties: Insee 2, Hi-brix-3, and ATS 12, two layers of corn husks: outer and inner and six fiber extraction methods: method 1 using 2.5 g/l alkaline solution, method 2 using 5.0 g/l alkaline solution, method 3 using 2.5 g/l alkaline and 0.5% enzyme solution, method 4 using 2.5 g/l alkaline and 1.0% enzyme solution, method 5 using 5.0 g/l alkaline and 0.5% enzyme solution, and method 6 using 5.0 g/l alkaline and 1.0% enzyme solution were utilized. The experimental design used was 3 ´ 2 ´ 6 factorial experiments in randomized complete block design. The results showed that the corn varieties, layers of corn husks, fiber extraction methods, interaction between the corn varieties and layers of corn husks, interaction between the corn varieties and fiber extraction methods, interaction between the layers of corn husks and fiber extraction methods, and interaction between corn varieties, layers of corn husks, and fiber extraction methods significantly affected cellulose, hemicellulose, and lignin content (p £ .01).
