Blackstrap

High test molasses (invert molasses) is produced from cane sugar when sucrose manufacture is restricted because of overproduction. The cane sugar at ca 55 wt % solids is en2ymatically converted to invert symp to prevent crystallisation and evaporated to a symp. The product is used in the same applications as blackstrap molasses. 

Uses. The primary use of molasses is in animal feed. Molasses, which provides a carbohydrate source, salts, protein, vitamins, and palatabdity, may be used direcdy or mixed with other feeds. The carbohydrate content of 24.6 L (6.5 gal) of blackstrap molasses is considered to be equal to 0.035 m (one bushel) of com as measured by the energy produced from 0.035 m of com and the amount of molasses required to produce the same amount of energy. When molasses is less expensive than com, sales increase when the reverse is tme, sales decrease. 

Molasses is also used as an inexpensive source of carbohydrate in various fermentations for the production lactic acid, citric acid, monosodium glutamate, lysine, and yeast (60). Blackstrap molasses is used for the production of mm and other distilled spirits. 

Although the hydrolysis of wood to produce simple sugars has not proved to be economically feasible, by-product sugars from sulfite pulping are used to produce ethanol and to feed yeast (107). Furthermore, a hemiceUulose molasses, obtained as a by-product in hardboard manufacture, can be used in catde feeds instead of blackstrap molasses (108). Furfural can be produced from a variety of wood processing byproducts, such as spent sulfite Hquor, bquors from the prehydrolysis of wood for kraft pulping, hardboard plants, and hardwood wastes (109).

Sugar made from either sugar beets or sugarcane is a perfectly acceptable product. However, the molasses produced from these crops is quite different molasses from sugar beets is an animal feed product, whereas molasses from sugarcane is marketed as a human food known as blackstrap molasses. 

Other products of sugar cane are edible sirup, blackstrap molasses, and invert molasses. Promising by-products, largely undeveloped as yet, include wax and aconitic acid from the filter press mud, and paper or building board from the expended, processed fiber, bagasse.

Diheterolevulosans (difructose dianhydrides) are obtained by refluxing concentrated aqueous solutions of D-fructose.96 97 Chromatography of Cuban blackstrap molasses in a pilot-plant-scale chromatogram on fuller s earth clay did not reveal the presence of these substances.98... 

Other acids (often as esters) have been found in fermented molasses. Usually these substances are products of bacteriological action and they are not normal constituents of unfermented molasses. Bauer" oil from the yeast fermentation of Cuban blackstrap consists chiefly of the ethyl esters of capric, lauric, myristic and palmitic acids.122 The fat from the scums of hot-room Louisiana molasses contained hexanoic (caproic) and octanoic (caprylic) acids.10 The occurrence of such volatile acids as propionic,128 butyric128 124 and valeric acids124 requires more adequate establishment. 

The concentration of fats and related substances in molasses is low analytical values depend on the extracting solvent.126 These tenaciously retained materials can be removed by fractionation of blackstrap on fuller s earth clay.70 Chromatography on a calcium silicate of the fat fraction of Cuban molasses led to the isolation of melissyl alcohol, a phytosterol fraction, chlorophyll a and a fat fraction containing a glyceride of linoleic acid.70 Stigmasterol and syringic acid are reported as ether-extractable constituents of molasses.127...
