Study of Effect of Different Parameters on The Extraction Yield of Mucilage From Salvia Hispanica Seeds

Abstract

Optimizing the parameters for maximizing the yield of mucilage from Salvia hispanica seeds is the principal aim of this research. There are four parameters that were evaluated in this research, namely; pH (ranges from 4-10), temperature (25-80°C), seed to water ratio (1:10-1:70 w/v), and seed to water contact time (3-24 h). Results showed that the yield of mucilage increased to an optimum pH of 7 and temperature of 60°C and then decreased thereafter. The yields increased to 1:40 (w/v) seed to water ratio and 12 h contact time but then leveled off. The mucilage yields that were attained under the optimal parameters were: pH 7 (9.57%), temperature 60°C (9.6%), seed to water ratio of 1:40 (9.61%), and contact time of 12 h (9.58%).
