Anti-caking Agent: Calcium Silicate (CaSiO3) Based on Snail Shell Waste and Rice Husk Ash

Abstract

In the present study, an attempt has been made to synthesize calcium silicate (CaSiO₃) made from snail shell waste and rice husk ash. This study aimed to determine the effectiveness of anti-caking of rice snail shell waste and rice husk ash and the morphological differences between synthetic and commercial anti-caking. Samples were characterized by Scanning Electron Microscope (SEM). The method used was a sensory test. The SEM results showed that prepared CaSiO₃ showed similarities to commercial CaSiO₃. After 14 days of observation, samples A and C (with 0.5 g CaSiO₃) increased free flow by 41.18%, while samples B and D (with 1 g CaSiO₃) had an increase of 45.90%. Interestingly, CaSiO₃, as an anti-caking agent made from snail shell waste and rice husk ash, was more effective in inhibiting clumping and could extend the shelf life of powdered milk with a percentage of 96% and 89%, respectively.
