Nutritional, Functional, and Anti‐Hypercholesterolemic Properties of Sourdough Breads From Unripe Plantain, Tiger Nut, and Fenugreek Flours

Food Chemistry International, EarlyView.
Composite sourdough breads were developed from blends of unripe plantain, tiger nut, and fenugreek flours. Optimized formulations improved pasting stability and enhanced texture, producing softer more elastic crumbs. The enriched breads contained higher dietary fiber and bioactive compounds, and significantly reduced serum cholesterol markers ...

Phase transition of lithium soap greases.

Journal of The Japan Petroleum Institute, 1986
The phase transition of lithium soap grease by differential thermal analysis (DTA) is described in this review paper. The phase transition temperature of lithium soap and its grease change as a function of the molecular weight of the soap. The transition temperature of grease and the structure of soap micelles formed in it are significantly affected by
