Influence of summer fallow on aromatic secondary products in sugarcane (Saccharum spp. hybrids)

Early Detection Cold Markers to Expedite the Sugarcane (Saccharum spp. Hybrids) Breeding

“…Naturally occurring fluorescence molecules in sugarcane juice include conjugated amino acids and polyphenols. 42 The fluorescence spectrum provides an estimate of the chemical structure, where higher excitation and emission wavelengths indicate a higher degree of conjugation or aromaticity. 43 Natural fluorophores are used as a rapid marker to monitor the quality of food and beverage products.…”

“…As described in detail elsewhere, 31 PARAFAC models three-way data (samples, excitation wavelengths, and emission wavelengths) by minimizing the sum of squares of the residuals. On the basis of residual/leverage analysis, core consistency diagnostic scores of 2−7 component models, and literature comparison, 32 a three-component model (57 core consistency) was selected to interpret the PARAFAC results.…”

Aconitic Acid Recovery from Renewable Feedstock and Review of Chemical and Biological Applications

“…For example, Gil Zapata [ 27 ] reported that variety L 97-128 had less than half the aconitic acid in tops/leaves when compared with cultivars LCP 85-384 and HoCP 91-555. Among the cultivars, HoCP 96-540, HoCP 04-838, HoCP 09-804, and L 01-299; HoCP 04-838 had significantly more trans -aconitic acid in the sugarcane juice (0.17%) when compared to the other cultivars [ 101 , 102 ], while HoCP 09-804 had more cis -aconitic acid than the others [ 102 ]. When a commercial process was developed for the recovery of aconitic acid from sugarcane streams, others noted that the sugarcane varieties were not grown for their high aconitic acid content but could be cultivated if so desired, at the expense of sucrose [ 99 ].…”

“…Furthermore, Haines Jr. and Joyner [ 99 ] attributed the higher aconitic acid content in Louisiana sugar cane molasses to the shorter growing season when compared to Florida-grown cane. Summer fallow had no significant impact on the aconitic acid concentration in sugarcane juice [ 102 ].…”
