<b>TRS value of sugarcane according to bioenergy and sugar levels

Abstract

ABSTRACT. In the specific case of sugarcane, producers in Brazil are currently paid by the content of total recoverable sugars (TRS) in the raw material when it reaches the industry, according to CONSECANA: TRS = 9.6316 *PC +9.15 * RSS, where PC is the Pol in cane (apparent sucrose) and RSS are reducing sugars in sugarcane (glucose + fructose). The objective of the project was to propose changes in the procedures used to mathematically determine the TRS, estimating the calorific value of moist cake and weight of moist cake. The final model is then proposed: TRS = 25.9892 + 0.02172*CVmc*WMC+0.536*WMC -4.14*CVmc + + 4.8158*PC + 4.575*RSS. Thus we obtain the TRS calculated according to the calorific value of moist cake (CVmc), weight of moist cake (WMC), Pol cane (PC) and the reducing sugars in sugarcane (RSS). This form is included in the estimation of TRS, the calorific value of moist cake, which reflects the bioenergy of fiber, weight of moist cake that estimates sugarcane fiber, in addition to existing factors Pol cane and reducing sugars in sugarcane. In the proposed model, the estimated values of TSR were 11.08% higher than the estimated values in the CONSECANA model.

No caso particular da cana-de-açúcar, os produtores são remunerados atualmente no Brasil pelo teor de açúcares totais recuperáveis (ATR) que a matéria-prima apresenta ao chegar à indústria, segundo CONSECANA: ATR = 9,6316*PC+9,15*AR, onde PC é a Pol da cana (sacarose aparente) e ARC são os açúcares redutores da cana (glicose +frutose). O objetivo do projeto foi propor alterações nos procedimentos utilizados para determinação matemática do ATR, estimando pelo poder calorífico do bolo úmido e peso do bolo úmido. O modelo final proposto fica então: ATR = 25,9892 + 0,02172* PCbu* PBU +0,536* PBU -4,14* PCbu + 4,8158*PC + 4,575* ARC. Assim tem-se o ATR calculado em função do Poder calorífico do bolo úmido (PCbu), peso do bolo úmido (PBU), Pol da cana (PC) e Açúcares Redutores da Cana (ARC). Desta forma inclui-se na estimativa dos valores de ATR o Poder calorífico do bolo úmido, que reflete a bioenergia da fibra, peso do bolo úmido que estima a fibra da cana, alem dos fatores já existentes, Pol da cana e Açúcares Redutores da cana. O modelo proposto estimou valores de ATR 11,08% superiores que o modelo Consecana.Palavras-chave: Saccharum, qualidade, biomassa.

Avaliação da produtividade e o perfil tecnologico de variedades de cana-de-açucar da região da Grande Dourados / Evaluation of productivity and the technological profile of sugar cane varieties in the Grande Dourados region

“…A concentração de sólidos solúveis (sacarose, glicose, frutose e outros) na canade-açúcar madura apresenta maiores percentagens, seguido pelo teor de ART açúcares redutores totais (glicose e frutose da sacarose) e, a POL (sacarose aparente). Portanto é de fundamental importância aguardar a cana atingir a maturação determinada pelos maiores teores de Brix e ART, para se obter melhores rendimentos principalmente para a produção de açúcar e derivados (MARQUES et al, 2015). Dentre os atributos analisados, o açúcar total recuperável (ATR) é um dos mais importantes tanto para indústria quanto para os produtores.…”

Minimizing the Costs of Biorefinery Feedstock by Managing Perennial Crop Age: The Case of Brazilian Sugarcane

“…The mix of outputs produced by the mill does not affect our modeling scenario, since all mills require a single input, total recoverable sugar (TRS) from sugarcane, as the feedstock for both the ethanol and sugarcane production processes (van den Wall Bake et al, 2009). In both cases, the mill's interest centers on acquiring sugarcane at the lowest cost (Marques et al, 2015). In a more general net present value maximization model, where the output mix and possibly the mill size were endogenous, the production possibility frontier between outputs, and prices and market structure in the output market would be relevant factors for inclusion, especially since, under the pricing system for independent producers, CONSECANA-SP, the sugarcane price depends on the output mix of the receiving mill (de Moraes and Zilberman, 2014).…”

Removal of phenolic compounds from sugarcane syrup and impact on Saccharomyces cerevisiae fermentation for β‐farnesene production

“…TRS in the samples was expressed in g L −1 and calculated according to Equation (6), where S , G , and F represented the sucrose concentration, glucose, and fructose, respectively.
