Abstract:
Spent coffee grounds (SCGs) were waste products from industrial, household,
and commercial coffee production. In addition, most spent coffee grounds were
improperly landfilled causing negative effects on the environment. Spent coffee
grounds also contained important nutrients and compounds that were able to be used
as ingredients in food. Therefore, the researcher studied the use of spent coffee
grounds as an ingredient in the production of fresh butter cookies by using fresh spent
coffee grounds and dry spent coffee grounds in an amount of 5 percent of the total
weight of the ingredients, it was found that the tasters commented that the fresh
butter cookies with dry spent coffee grounds resulted in dark cookies, crispier than
those using fresh spent coffee grounds and it had less coffee aroma than cookies with
fresh spent coffee grounds. The sensory testing aspect found that the tasters rated the
butter cookies supplemented with fresh spent coffee grounds more favorably than the
dry ones. Moreover, the appearance, color, aroma, taste, and texture were not
significantly different (p>0.05). This study was conducted on the appropriate amount
of spent coffee grounds in butter cookies at 4 levels, namely 0, 3, 5, and 7 percent of
the total ingredient weight. It found that the amount of spent coffee grounds added
to butter cookies had the different effect on the quality of butter cookies (p>0.05).
When spent coffee grounds were supplemented with increasing amounts, the results
of L* a* and b* values decreased differently (p>0.05). However, the crispness value of
fresh butter cookies tended to increase when the amount of spent coffee grounds
were increased. When there was a sensory test, it found that tasters rated butter
cookies supplemented with spent coffee grounds more than butter cookies with no
spent coffee grounds added. In this regard, tasters rated the butter cookies that were
supplemented with 7% spent coffee grounds the most (p<0.05), which had lower
nutritional value in terms of energy and fat. However, protein and dietary fiber were
increased, and also had 0.02 percent of caffeine when compared to butter cookies
without added spent coffee grounds. Consumers accepted the fresh butter cookie
product supplemented with 100.00% coffee grounds.
