Abstract

This study was carry out to determine the content of simple sugar inside the bakery waste hence polysaccharide was extracted and to be dried to obtain powder. The experiment is designed by accordingly from preparing sample, extraction, and freeze dry. At first, polysaccharide was extracted using microwave-water extraction method. To determine glucose content inside the extraction yield, DNS method was done. Value of glucose was able to determine with help of standard curve of glucose. Then, different amount of drying agent (maltodextrin) was added before it was freeze dry to obtain powder. After the yield obtained, several physiochemical and physical analysis was conducted where it able to determine moisture content, real, tapped and bulk density of the powder. The percentage of extraction yield obtained for both sample donut and croissant are at 7.08% and 12.22% respectively. While highest polysaccharide powder obtain is at 20% of maltodextrin where.20.28% for donut and 12.21% for croissant. The lowest moisture content value recorded at 20% maltodextrin where 6.36 for donut and 3 .87 for croissant. The bulk, tapped and real density of donut and croissant recorded the lowest is at 20% of maltodextrin (0.18, 0.30, 0.09 for donut and 0.17, 0.29, 0.09 for croissant) and the highest 10% (0.21, 0.33, 0.12 for donut and 0.22 0.32, 0.10 for croissant). The fastest polysaccharide powder dissolve time for donut and croissant recorded is at 20% maltodextrin which is 10 minutes. The result shows that, at higher percentage of drying agent, polysaccharide powder obtained higher, low moisture content, faster dissolve time and moderate density of product. Hence, the higher the value of drying agent added, the better the properties of polysaccharide powder.
