Diseño de un proceso industrial para la elaboración de crema hidratante a base de suero con aloe vera (Aloe barbadensis) en la planta experimental de lácteos Tunshi - ESPOCH

Abstract

The objective of this technical project was to design an industrial process for the elaboration of moisturizing cream from milk serum with Aloe Vera (aloe barbadensis) for the Tunshi- ESPOCH Dairy Experimental Plant, for which different formulations of cream with serum at different concentrations, the best formulation was chosen. It began with the collection of milk serum as raw material generated in the Dairy Experimental Plant, the physical- chemical and microbiological analyzes were carried out according to the NTE INEN 2594: 2011 Liquid serum standard. Requirements in the SAQMIC laboratory, which allowed us to determine the quality of the raw material. In addition, to determine the design conditions, obtain the process variables, and perform the engineering calculations for the respective equipment. Different tests were carried out to establish the adequate amount of serum in the elaboration of the product, moisturizing cream, its formulation is 80% serum / L, the pH, and its viscosity was also analyzed. For the validation of the process to the sample, tests were carried out according to the NTE INEN 2867 Standard "COSMETIC PRODUCTS" in the MULTIANALITYCA CÍA LTDA laboratory. The analyzes carried out showed that the cream has a characteristic odor and color, a homogeneous appearance free of foreign material, Mesophilic Aerobes, Escherichia Coli absence, Staphylococcus Aureus absence, pH: 4.90, The power for the mixer is 2.68 Hp and two tanks for the aqueous phase and the oil phase. The use of fresh serum is recommended to avoid its acidification and that the producto can comply with the required standards.
