Amino acid and fatty acid composition of cane molasses

Abstract

Cane molasses contain both protein and non-protein amino acids and fatty acids. Gas chromatographic evidence is presented for aspartic and glutamic acids and alanine, being the major acids out of the 18 protein amino acids determined. Two unidentified N-containing free acids, eluting faster than alanine and other protein amino acids on EGA column, are of particular interest. Linoleic (C18:2) is by far the most important fatty acid found. Other major fatty acids are palmitic (C16: 0), oleic (C18: 1) and arachidic (C20: 0).

Fatty acid composition of cane molasses and yeasts

“…Table 1 shows that all the molasses have the same fatty acids in the following order: linoleic, palmitic, oleic, linolenic, stearic and other minor acids. These results show the presence of linolenic acid which was also reported by BALCH (1953) in Louisiana sugarcane, but was not detected by MEE et al (1979) for Hawaii cane molasses. The lipid extract in molasses varied from 1.02 to 3.13 g/kg.…”

“…These variations may be due to the extent of sucrose extraction in different sugar factories. The results of lipid extract were lower than those related by MEE et al (1979), perhaps because they did not purify the chloroform extract with petroleum ether as it was performed in this experiment. The level of linoleic acid in molasses is considered adequate for yeast growth (GUTIERREZ, 1991).…”

“…Therefore, the fatty acid composition of the yeasts used in distilleries can reflect molasses composition. Linoleic acid is the most important fatty acid in Louisiana sugarcane (BALCH, 1953) and in Hawaii cane molasses (MEE et al, 1979). There is no available data for Brazilian sugarcane molasses.…”

Effect of substitution of corn for molasses in diet on growth performance, nutrient digestibility, blood characteristics, fecal noxious gas emission, and meat quality in finishing pigs

“…) and could be considered an alternative for cereals . Cane molasses, which was used in this study, usually contains sucrose, protein, non-protein amino acids, and fatty acids (Mee et al, 1979). It can reduce the cost of diets, because the price of molasses is much lower than that of cereals in livestock feedstuffs.…”

Media components and amino acid supplements influencing the production of fruity aroma by Geotrichum candidum

“…Sugarcane molasses is one of the byproducts of the refinery process (18) that is traditionally used for culture media in various industrial fermentations (12). Molasses is composed of sugars (86ºBx), nitrogen compounds including crude proteins (8.2%), ash (16%) and fatty acids (0.3 -1%) (U.S Sugar Corporation Molasses and Liquid Feeds Department -www.suga-lik.com/molasses/composition.html).…”
