Study of Cracker Production with the Addition of Black Garlic and Sodium Tripolyphosphate

Abstract

This study examines how black garlic and sodium tripolyphosphate (STPP) concentrations effect cracker physical, chemical, and organoleptic characteristics, also determined the black garlic and STPP optimal concentration to produce cracker with desirable quality. A completely randomized design was used, with two factors: black garlic concentration (3%, 6%; 9%) and STPP concentration (0.1%; 0.3%; 0.5%). The test parameters were color (lightness), swelling power, hygroscopicity, water content, ash content, total polyphenols, antioxidant activity, and organoleptic tests (color, flavor, taste, crispiness, and overall). An effectiveness test was conducted to determine the black garlic and STPP right concentration in cracker production. The results showed that the black garlic concentration significantly effected the lightness, swelling power, hygroscopicity, water content, ash content, antioxidant activity, and total cracker polyphenols. STPP concentration significantly effected the cracker ash content. Garlic and STPP concentration had significant organoleptic effects on color preference, flavor, taste, and crispiness. The cracker with a concentration of 3% black garlic and 0.5% STPP were the best and preferred. The effectiveness score was 0.64, with physical characteristics of color lightness 23.39 ± 0.20, swelling power 82.51 ± 0.11%, hygroscopicity 5.07 ± 0.41%, and chemical characteristics of water content 5.83 ± 0.16%, ash content 2.77 ± 0.25%, total polyphenols 0.175 ± 0.001%, antioxidant activity 16.14 ± 0.20. The organoleptic test scores were color 6.00±0.12, flavor 5.60±0.43, taste 5.68±0.31, crispiness 6.92 ± 0.32, and overall 6.28 ± 0.42.
