Production of Cellulose from Barley Husks as a Partial Ingredient of Formulated Diet for Tilapia Fingerlings
Abstract
Cellulose is the most abundant renewable polysaccharide on earth and it is widely used in many aspect and industries such as food industry, pharmaceutical, and many more. Due to the increasing demand in the market, studies and work to produce cellulose are still rapidly developing. In this study, barley husks was pretreated in hot water at 100°C and followed with liquid oxidation process with 30% H2O2 at 60°C. Through the hot water treatment, cellulose in the barley husks was successfully recovered as glucuronic acid, saccharides, cellulose and thus leaving fats. Results obtained also show that after treatment, the barley husks is made up 66.00% cellulose. This cellulose can be used as source of the digestible carbohydrate in fish feed which can help in reducing the cost of feed production.
