to determine the effect of the concentration of catechins from Uncaria gambir on the shelf life of anchovies. Preservation of anchovies in this study was carried out by soaking them in a catechin solution (0%-15% concentration) with a ratio of 1:4 for ±2 hours. The treated anchovies were dried in an oven at a temperature of ±50 o C for 12-24 hours and packaged using polypropylene (PP) plastic. To determine the shelf life of anchovies, storage was carried out for 30 days, every 15 days an analysis was carried out to determine the quality of the product. The results showed that anchovy preserved using catechins at a concentration of 10% (A3) can reduce the number of bacteria (1.10x10 5 colonies g -1 ) with water and ash content were 18.1339% and 10.5358% respectively. The organoleptic test at the same concentration had a very favorable value for texture and aroma, but the panelists did not like the color because it produced a darker appearance than without immersion in catechin (A1). The product shelf life test for up to 30 days still met the standard of dried anchovy (SNI.01-3391-2000) and the organoleptic test had decreased the texture and color values, where the product became less compact and the color became darker.
