PEMBUATAN BISKUIT DARI PASTA UBI UNGU (Pasta Diproses Menggunakan Rotary Evaporator)

Abstract

The provision of breast milk (ASI) cannot optimally fulfill the increasing nutritional needs of infants after entering the age of 6 months, so it must be balanced with complementary feeding of breast milk (MP-ASI). One of the foods that contain lots of nutrients for babies is purple sweet potato. Purple sweet potato can be processed into a paste for raw materials for making biscuits as complementary food for ASI (MP-ASI). The aim of this research is to make biscuits according to SNI No. 01-7111.2-2005 using raw material for purple sweet potato paste. The concentration of bait used was 62.5%, 55.5% and 50%. Purple sweet potato paste is made using a rotary evaporator. The results showed that the optimum operating conditions for the rotary evaporator in producing the paste were at a feed concentration of 55.5%, the viscosity, density and water content values obtained were 311.4176 mPa.s, 1.0885 gr / mL and 57.7578%. The paste produced from the rotary evaporator is then used to make purple sweet potato biscuits. The analysis showed that the carbohydrate, protein, fat and water content were 39.30%, 8.42%, 20.35% and 16.05%. The purple sweet potato biscuits that were produced were close to SNI No. 01-7111.2-2005.
