Abstract

Pumpkin is an agricultural output that can be processed into flour due to its carbohydrate contain which is 75%. Processing pumpkin become flour could cause the browning. Immersion process using sodium metabisulphite and citric acid can used for preventing the browning reaction. This study aimed to determine the effect of types of anti-browning agents and long immertion time on the physicochemical characteristic of pumpkin flour, and to determine the interaction between the types of anti-browning agents and long immertion time on the physicochemical characteristic of pumpkin flour. This study used a factorial Completely Randomized Design (CRD) and consisted of 2 treatment factors, namely types of anti-browning agents (sodium metabisulphite and citric acid solution) and long immersion time (10, 20 and 30 minutes). The parameters observed in physical characteristics (bulk density, browning index, , and yield, color) and in chemical characteristics (water content, ash content, carotene). The results showed that types of solutions had significant effect on yield, browning index, color, ash content, and carotene, while the results showed that long immersion had significant effect on bulk density and carotene. Furthermore, interaction between types of solutions and long immersion time had significant effect on bulk density. A2B3 treatment (sodium metabisulphite 30 minute) was the best treatment with value of yield 0.79%, bulk density 0.79 g/mL, browning index 0.48, lightness 63.3%, redness 24.47, yellowness 38.8, water content 6.07%, ash content 3.97% and carotene 29.41mg/L.
