dc.description.abstractIn industry, there are large amount of pineapple skins, cores, leaves, etc (waste-products) are thrown after processing. Most of farmer sold them for dairy cow’s farm or used it in feeding for their own cow, but the profit of these ways was not significant enough. However, reusing of pineapple trash can improve the economic benefits. In real situation, 1liter of milk’s cow (about 0.89 kg) cost 5- 10 USD, 1kg cow’s meat cost 10-12 USD but 1kg bromelain cost 200 USD while the production costs of extraction are cheaper than building a big farm. Pineapple’s wastes are a main source for extraction of bromelain and this enzyme needed in this social life because of its application in various fields like medical, food and cosmetics. This thesis was aim to the extraction of bromelain from waste product (outer skin and core) and finding the optimum condition of this process.The results of this thesis prove that the highest of bromelain activity when mixing the pineapple juice withammonium sulfate 80% concentration was 42.5 UI/mg. After this research, a new way for treating pineapple’s trash may be establish. All of the chemicals of this research were bought from China with Bach Khoa chemical company is distributor and the equipments of Food Engineering Lab were bought from Germany (Merk). The new Anson method was applied in calculating activity of bromelain and the protein determination of bromelain was estimated by Lowry method.en_US
