Effect of the Addition Tilapia Skin Collagen Concentration to Lotion Characteristics

Abstract

The purpose of this research was to determine the best concentration of the tilapia skin collagen addition to obtain the characteristics of the lotion in accordance with the established standards. The research was carried out at the Fishery Product Processing Technology Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Central Laboratory of Padjadjaran University and Faculty of Mathematics and Natural Sciences Laboratory of Padjadjaran University between March 2021 - June 2021. The method used in this research was experimental with a completely randomized design consisted of 5 treatments with 4 replications added the concentration of the tilapia skin collagen (0%, 4%, 5%, 6% and 7%) based on lotion formulations. Parameters observed included pH, viscosity, spreadability, weight loss, homogeneity and the organoleptic (appearance, color, scent, texture). The conclusion from this research was that the addition of 7% the tilapia skin collagen concentration was the best treatment with a homogeneous appearance, a slightly yellowish white color, a slightly lavender scent and a slightly thick texture. The lotion had pH value of 6.35, viscosity of 7,197 cP, 5.74 cm spreadability and a weight loss of 2.8%.
