Produção de fosfato de diamido fosfatado a partir do amido de mandioca (Manihot esculenta)

Abstract

The Phosphated distarch phosphate (INS 1413) is a modified starch obtained through a combination of chemical modifications in the structure of the native starch, in this case, cassava starch (Manihot esculenta). It is indicated to be used in frozen or refrigerated products, since this starch has a better behavior in terms of freezing and unfreezing cycles than native starches. Considering that the modified starches market is very diversified and has a high economic value and there is a constant search for starches with specific characteristics to comply with the necessities of this sector, we present the AMIDIFIC industry project. The company proposes a product to replace fats in food products, through the production of phosphate-modified cassava starch. Through market analysis, it was decided to install the company in the city of Maringá (PR) due to the proximity of likely suppliers. From the production route, it was decided to use sodium tripolyphosphate (STPP) and sodium trimetaphosphate (STMP) as modification reagents. Finally, the feasibility of the project was validated, since it presented a positive net present value (NPV) and profits within the second year of production. The project proved to be viable for an annual production of 20,390 tons of Phosphated distarch phosphate, operating for 260 days a year.
