The fried crisp chips have low nutrients. In this research developed fried crisp chips to enrichment by adding Jerusalem artichoke powder. Jerusalem artichoke has inulin as the main component. Have properties of a prebiotic with beneficial to health. So, the objective of this research was to study the effect of Jerusalem artichoke powder on physicochemical and sensory properties of fried crisp chips. Jerusalem artichoke tuber will be processed into powder and added in the basic recipe of fried crisp chips. The ratio of tapioca starch per Jerusalem artichoke powder is 95:5 90:10 and 85:5 or 5 10 and 15% by weight of ingredients tapioca starch and Jerusalem artichoke powder, respectively. When the amount of Jerusalem artichoke powder increased color of fried crisp chips has more dark, many cavitation but the size of small, expansion capacity decreased and hardness increased. The sensory tests found that the formulations of fried crisp chips added Jerusalem artichoke powder 10% has most scored compared to other recipes. Apply the formula of fried crisp chips with 10% Jerusalem artichoke powder develop taste by Just about right test (JAR test) in sweetness, salinity, spicy and garlic flavor. The formula of final fried crisp chips product has ingredients be 90% of tapioca starch, 10% Jerusalem artichoke powder, 4.5% sugar, 3% salt, 11% pepper, 5% garlic and 60% water of the weight of tapioca starch and Jerusalem artichoke powder. Test the final product for consumer acceptance by 100 people found that the score overall results are moderate and accepts product .......%
