Influence of Fenugreek Gum and Particle Size on Performance of Talc Flotation

Influence of Fenugreek Gum and Particle Size on Performance of Talc Flotation

In this work, the effect of fenugreek-gum (FG) on the depression of talc with different particle sizes and the depression mechanism were systematically investigated. The floatability of talc was influenced by the granularity, and the floatability of talc in different particle sizes followed the order: -0.074+0.037mm > -0.037mm > -0.010mm. FG had a strong depressing effect on talc, especially for coarse talc, the -0.074+0.037mm size fraction of talc was completely depressed by 2.5 mg/ dm3 FG. The depressing effect of FG for talc was influenced by particle size. Larger dosage of FG was needed in order to completely depress talc with smaller particle size. The absolute value of talc surface charge and the inter-particle repulsion decreased in the presence of FG, causing easier inter-particle flocculation. FG interacted with talc surface by chemical adsorption.

Investigational Studies on Highly Purified Fenugreek Gum as Emulsifying Agent

Investigational Studies on Highly Purified Fenugreek Gum as Emulsifying Agent

In this study, highly purified galactomannan containing fenugreek gum was isolated by newly reported method and investigated for its surface and emulsification property. Comparative studies were carried out with other galactomannan containing natural emulsifiers like locust bean gum, guar gum, and non-galactomannan anionic xanthan gum. The results revealed that highly purified fenugreek gum has better surface and interfacial tension reducing property among all gums used in this study. Emulsion prepared with 0.6% highly purified fenugreek gum showed greater reduction in droplets size with greater surface area compared to guar gum, locust bean gum, and xanthan gum emulsion. Zeta potential values indicated that highly purified fenugreek gum emulsion showed greater repulsive forces and was able to form more stable emulsion compared to other gums. No coalescence or phase separation was observed during storage.

Fenugreek Gum: A Versatile, Natural, Sustainable Gum for Health & Industry

Fenugreek Gum: A Versatile, Natural, Sustainable Gum for Health & Industry

Fenugreek gum is a natural, biodegradable, and sustainable hydrocolloid. The fenugreek seeds contain 26.8% soluble fiber. Because of its properties, fenugreek gum provides texture, appeal, gelling, thickening, emulsifying, stabilizing, and encapsulating properties.
