Value-added analysis of Lactobacillus acidophilus cell encapsulation using Eucheuma cottonii by freeze-drying and spray-drying

Abstract

Abstract The added value of Lactobacillus acidophilus encapsulation due to its production process is one of the first things that need to be known in calculating techno-economic analysis to determine the sustainability of its downstream. The result of value-added analysis plays an important role in determining which formulation, encapsulate material, and production process should be used. The inoculum media used were skimmed milk and whole milk, the coating material used in this study was Eucheuma cottonii, while the process variations used were spray-drying and freeze-drying methods. There were four treatments in the research that analyzed their added value. Determination of the best treatment was carried out through the scoring method on the value of cell viability, cell morphology, encapsulation effectiveness, process costs, cost of supporting materials, and added value of the product. Added value analysis was carried out using the Hayami and Kawagoe methods. Based on the research results, it can be concluded that added value is most influenced by process costs. The treatments selected were E. cottonii coating material, fresh milk inoculation medium, and spray-drying encapsulation method with an overall score of 22.
