Inulin is an essential part of the family of complex carbohydrates, which actively participates in industrial applications, since it is an active ingredient of several vegetative species of tubers and roots. In developing countries, there are no inulin production industry from biomass. This carbohydrate is only imported as active ingredient of pharmaceutical drugs and quantification in already elaborated products. These are the reasons, why it is extremely important the development of inulin industrial production. This research aims to design a technological process to produce inulin from garlic biomass (Allium sativum), starting from the state of the art analysis of the field, which prioritizes the study of inulin extraction from garlic by solid-liquid extraction at laboratory scale, using water as solvent. The influence of the variables water / garlic ratio: 2, 3 and 4 ml water / g garlic and the temperature: 30, 55 and 80 °C on the extraction process, during 45 minutes, with constant agitation was assessed. The refining obtained from the filtration of the extract was quantified; the results indicate that garlic contains about 18% of inulin and the best extraction conditions are: temperature at 80 °C and water / garlic ratio of 4. A pilot-scale sustainable technology was designed and simulated with SuperPro Designer software from a raw material input capacity of 10 kg/batch. A comparative analysis was made on the feasibility and possibilities of implementation of the different flow works.
