Molasses
Molasses is defined as the syrupy mother liquor left after sucrose has been removed from the cane juice by concentration. If only one crop of crystals had been removed, it is called First Molasses. If the second crop has been removed, the product is termed Second Molasses, and so on. When no more cane sugar can be extracted it is called Final Molasses or Black Strap Molasses.
Peanut Butter
Peanut butter is made from mixing ground up peanuts with various additives and fillers. From the mixer, peanut butter is pumped through a deaerator and/or heat exchanger to remove entrained air and drop the temperature prior to being pumped to the jar filling machines.
Soaps
Kettle soap, soap stock, soap skimmings, and liquid soap are a mixture of sodium salts of various fatty acids of natural oils and fats. Common soap is largely a mixture of the sodium salts of palmitic, stearic and oleic acids. Rosin soaps for laundry purposes are made by adding a soap made from rosin or rosin itself to an ordinary soap.
Surfactants
Surfactants reduce the surface tension of the liquid in which they are dissolved. Commonly used in cleaning products to emulsify oils and hold dirt or other particulates in suspension. Also used in chemical processing like ethanol production.
Detergent Slurry
Detergent Slurry is a blend of liquid surfactant with powdered and granulated materials, such as builders and additives, that help to improve surfactant and cleaning performance.
