“…Considering the effect of flocculants on the sugar ash, an effect was found only for the CTC14 variety, and the CSP, MLE and COP resulted in lower values in relation to other parameters. Costa et al (2015) found the same behavior when using CSP and MLE as clarifying agents of juice from variety RB867515 processing, and the resulting sugar presented lower ash content. These elements are directly detrimental to the refining industries since they reduce the performance and efficiency of the factory, adversely affecting product quality (Albuquerque, 2011).…”

Acrylamide replaced by moringa extract in sugar production

et al. 2018

This manuscript showed a new product that can be used in sugar and alcohol production to replace the acrylamide polymer, applied in the juice treatment. This new product is an organic extract obtained from moringa seeds, which present the flocculating protein 2S-Albumin. This biomolecule is added in the decanter together with the limed and heated juice, increasing the sedimentation speed of impurities that, if remain in the process, decrease the quality of the obtained sugar. This issue is of great importance because the acrylamide molecule has carcinogenic and neurotoxic action in humans and may be incorporated within the sugar crystal or the mud (filter-cake) used as a fertilizer. Furthermore, it should be noted that this manuscript presents the best technique to extract the S-Albumin protein from moringa seeds (using a CaCl 2 solution 0.1 mol/L), the best dosage to apply in the sugarcane juice (1300 mg/L), and similary sugar quality achieved, compared with the process using the acrylamide polymer.

“…This explanation could respond the behavior of sugarcane juice fermentation, which is a complex medium and presents a high concentration of these same elements. Costa et al 24 obtained for sugarcane juice the concentration of 50–130 mg/L calcium, 500–2000 mg/L potassium, 20–80 mg/L sodium, 140–150 mg/L magnesium, 4 mg/L manganese and 5 mg/L iron. In this way, we could infer that the elements in the juice affect the biomass production by R. rubra , but is important highlight again the action of magnesium, once increased the level of dry biomass.…”

In order for the use of biological carotenoids to become feasible, it is necessary to have adequate low cost sources and improved methods of cultivation. The aim of this study was to evaluate the effect of supplementation with nitrogen, phosphorus, zinc, and magnesium, on the biomass and carotenoid volumetric production by yeast Rhodotorula rubra L02 using a complex medium (sugarcane juice) and synthetic media (sucrose and maltose) as substrates. The experimental design used for each substrate was randomized in blocks with 16 treatments and 3 repetitions. The treatments were compound for 15 different combinations of nutrients (N; Mg; Zn; P, N + Mg; N + Zn; N + P; Mg + Zn; Mg + P; Zn + P; N + P + Zn; N + P + Mg; N + Zn + Mg; P + Zn + Mg; N + Zn + Mg + P) alone and combined, and a control. The results were submitted to analysis of variance and Tukey test at 5% significance level. Among the treatments evaluated, the highest production of dry biomass, with both maltose and sucrose, was observed for Mg (1.60 g/L and 1.94 g/L, respectively). Additionally, another treatment that stood out in terms of biomass production was the control treatment with maltose (1.54 g/L). After the incubation time, killer activity was not observed since there was no formation of inhibition halo around the L02 yeast.

“…After analyzing the scientific articles, nine publications were identified that adopted alternative methods considered less common, and that can replace sulfitation in the clarification of sugarcane juice (DOHERTY, 2011;ORTIZ et al, 2011;LAKSAMEETHANASAN et al, 2012;COSTA et al, 2014;COSTA et al, 2015;GALDINO et al, 2019;TEIXEIRA et al, 2019;TIWARI et al, 2019;LEITE and BARBOSA, 2021).…”

The search for alternative methods to replace sulfur in the sugarcane juice clarification step has been increasing. The sulfur dioxide (SO2) produced in the combustion of sulfur is toxic and can cause environmental problems and risks to human health. This work aimed to analyze scientific articles on alternative methods to sulfitation published between 2011 and 2021, based on searches in the Portal de Periódicos Capes, Scielo and Web of Science. Among the 434 researched scientific articles, 296 were repeated and 138 were unique, of which 94 had the text available in full and 44, unavailable. Thirty were selected to compose this review, for reporting on alternative methods of clarification: carbonation (4), ozonation (6), peroxidation (5), microfiltration (6), natural flocculants (5), bagasse fly ash (1), centrifugation (1), lime, bentonite and activated carbon (1), lime saccharate, ammonium hydroxide (NH4OH) and sodium hydroxide (NaOH) (1). All methods proved to be effective and less polluting, in addition to reducing the consumption of chemical reagents.
