Abstract

Jember potential to become one of the world's coffee suppliers. The survey showed that farmers need to add the sorting stage in the processing of coffee to get good quality coffee beans and uniforms. Stages of the process that needs to be improved is the stage of drying and storage. At the stage of drying, need to improve standards of drying up to 12.5% (SNI) as a standard in use today are still high enough to 14%. Water content is still possible to increase especially during storage and hence, potentially causing the growth of Aspergillus ochraceus as a ocratoxin producer. At the storage stage, the coffee must be placed in clean bags and stacked on a wooden base, and does not stick to the wall. This is done to avoid increasing the water content in the coffee because of moisture on the floor and walls. From the analysis of water content is known that an increase in product moisture content of 13.6% to 13.9% during storage.

Abstract

The compound β-glucan is a polymer of glucose, which is polymerized through betaglycoside bond. The compound β-glucan has anti-tumor benefits, reducing the risk of heartdisease, lowering cholesterol and so forth. The compound β-glucan can be produced by thefungus in ukstraseluler. One of the molds that can produce compounds in the extracellular β-glucan is Epicoccum nigrum, often called epiglucan. The purpose of this study was to determinethe effect of aeration and oxygenation to the production epiglukan by Epicoccum nigrum inmolasses media. This research was conducted using descriptive method with 3 under controlledconditions : anaerobic, aeration and oxygenation in the Stired Continuous Tank Reactor (batchculture). The parameters observed were the biomass (g / L), epiglucan (g/L), reducing sugarcontent (%) and pellet diameter are formed. Biomass and highest epiglikan obtained inoxygenated conditions which amounted to 7.074 g / L and 2.01 g / L. The resulting biomasspellet-shaped with the largest diameter occurs in conditions of oxygenation that is 0.37 mm.residual reducing sugar at the end of fermentation the greatest there is in the anaerobiccondition is 1.529%
