Penentuan faktor faktor yang memepengaruhi umur simpan dan penentuan umur simpan orange emulsion flavor dengan metode ASLT di PT. Firmenich Indonesia
Abstract
Stability of emulsion product such as emulsion flavor is depend largely on interaction between hydrophilic and hydrophobic part of the product. Flavor compounds are generally soluble in oil (oil soluble), insert of these compounds in an emulsion makes it possible to deliver oil-soluble components into the water based. This research aims to estimate the shelf life of stabilized emulsions flavor using Accelerated Shelf Life Testing (ASLT) method. In this method, the storage condition is out of normal so that the deterioration will be occurred in a shorter time. Storage temperatures that used in this research were 20°C, 25°C,30°C and 35°C. Arrhenius equation used as a model in the estimation of shelf life with acceleration method. Arrhenius equation is an approach that uses the kinetic theory, which generally have reaction order 0 or 1 for food. The parameters that can be quantitatively measured are required to analyze the decline of quality with acceleration method. The parameters that used in this research were size particle, odor, spesific gravity, color and microbial. Based on the analysis of particle size, the shelf life of orange emulsion flavor are 0,266 months at 25 ° C. Based on the analysis of sensory attributes of smell, the shelf life of orange emulsion flavor are 5.38 months at 25 ° C, And based on the analysis of sensory attributes of color , the shelf life of orange emulsion flavor are 2.55 months at 25 °. The factors most influential in determining the shelf life of orange emulsion flavor based on AHP analysis include: homogenization, stabilizer, flavor, emulsifier, and type of packaging. While the final quality of the product parameters orange emulsion flavor are: particle size distribution, microbiology, flavor, pH, specific gravity, refraction index, and color.
