Improving The Quality of Coconut Cream-Based Pasta Through The Presence of Sago Starch and Surfactants: Application As An Ingredient of Rendang Seasoning

Abstract

Coconut processed products (coconut cream) are widely used in the food field. However, various ways, such as adding starch and surfactants still need to be made to improve the stability of coconut cream. This study aimed to evaluate the addition of starch and surfactant on the stability of coconut cream and its use as an ingredient of rendang spices. The separation of coconut milk into coconut cream was conducted using the cold method (4oC for ± 18 hours) and cream separator method. After that, Hydrophilic-Lipophilic Balance (HLB) 5 (1%) surfactant and sago starch (3% and 5%) were added to the coconut cream to produce a coconut cream paste, which was later used as an ingredient in the rendang seasoning. The quality parameters of coconut cream such as zeta potential, viscosity, free fatty acid content were evaluated in this study. The results showed that the cream separator method with 1% surfactant HLB 5 and 3% sago starch produced coconut cream paste with a zeta potential of -30.5 mV and free fatty acid of 0.1%. This method was suitable for use as an ingredient of rendang seasoning indicated by a viscosity of 699.9 cPs, lightness of 32.51, and pH of 4.41. Therefore, the cream separator method could improve the coconut cream stability and be applied to rendang seasoning.
