viscous
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.

The term "soy molasses" was coined by Daniel Chajuss, the founder of Hayes Ashdod Ltd., which first commercially produced and marketed soy molasses in the early 1960s. The name was intended to distinguish the product from “soybean whey” or “condensed soybean solubles”, the by-products available at the time from soy protein isolate and acid washed soy protein concentrate production.
Manufacture
The alcohols are removed from the liquid extract by evaporation and the distillation residue is an aqueous solution of the sugars and other soy solubles. This solution is concentrated to viscous honey-like consistency to yield soy molasses.
Composition
Typically, soy molasses contains 50% total soluble solids. These solids consist of carbohydrates (60%), proteins and other nitrogenous substances (10%), minerals (10%), fats and lipoids (20%). The major constituents of soy molasses are sugars that include
oligosaccharide
An oligosaccharide (/ˌɑlɪgoʊˈsækəˌɹaɪd/; from the Greek ὀλίγος ''olígos'', "a few", and σάκχαρ ''sácchar'', "sugar") is a saccharide polymer containing a small number (typically two to ten) of monosaccharides (simple sugar ...

), disaccharides (sucrose) and minor amounts of monosaccharides (fructose and glucose). Minor constituents include saponins, protein, lipid, minerals (ash), isoflavones, and other organic materials.
Use
Soy molasses is used as a feed ingredient in mixed feeds as pelleting aid, added to soybean meal (e.g. by spraying it into the soybean meal desolventizer toaster), mixed with soy hulls, and used in liquid animal feed diets. Soy molasses can be used as a
