Similarly‚ urea treatments had slightly increased the lignin content of retted kenaf fibres across the varieties. However‚ there was a significant reduction in hemi-cellulose content of kenaf fibres retted in 1% urea solution compared with others. 2% urea retted fibres had the highest ash content (0.8- 1.05%)

States behind it.To make pulp from wood‚ a chemical pulping process separates lignin from cellulose fibers. This is accomplished by dissolving lignin in a cooking liquor‚ so that it may be washed from the cellulose fibers. This preserves the length of the cellulose fibers. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper. This is because they do not contain lignin‚ which deteriorates over time. The pulp can also be bleached to produce white

Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide

and lignin components. 6. (5)What do crude fiber‚ ADF‚ NDF and TDF actually measure? The method for determining crude fiber consists basically of measuring the residue remaining after acid and basic hydrolysis. It is known that the crude fiber method covers 50%-80%of the cellulose‚ 10 %- 50% of the lignin‚ and 20% of the hemicelluloses. http://archive.unu.edu/unupress/food/8F024e/8F024E09.htm Acid Detergent Fiber (ADF) is a measure of the fibrous part of a plant (cellulose and lignin) that

It is derived from the complex conversion network of the three main components in biomass: cellulose‚ hemicellullose and lignin (Kan et al.‚ 2016). Degradation Characteristics of A. magnium wood The purpose of this research is to determine the main points of A. magnium thermal degradation‚ based on DTG data. The data of the thermal stability of biomass was analysed. The

Dietary Fiber consists of non-digestible carbohydrates and lignin that are intrinsic and intact in plants. Functional Fiber consists of isolated‚ non-digestible carbohydrates that have beneficial physiological effects in humans. Total Fiber is the sum of Dietary Fiber and Functional Fiber.

Dietary Fiber Dietary Fiber is the parts of plant that resist digestive enzymes. A few definitions of dietary fibers are nondigestible carbohydrates and lignin that are intrinsic and intact in plants. nondigestible carbohydrates and lignin that are intact in plants. Another definition is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine‚ with complete or partial fermentation in the large intestine.
