TRS value of sugarcane according to bioenergy and sugar levels

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.

针对甘蔗这一特定品类，根据巴西蔗糖工业全国联合会（CONSECANA）的现行规定，当前巴西甘蔗生产商的结算依据为原料运抵工厂时的总可回收糖分（total recoverable sugars, TRS）含量，其原有计算公式为：TRS = 9.6316 × PC + 9.15 × RSS，其中PC为甘蔗锤度（Pol in cane，表观蔗糖含量），RSS为甘蔗还原糖（葡萄糖+果糖）。本项目旨在改进当前用于数学计算总可回收糖分的流程，同时对湿滤饼的热值与湿滤饼重量进行估算。最终提出的改进模型如下：TRS = 25.9892 + 0.02172×CVmc×WMC + 0.536×WMC − 4.14×CVmc + 4.8158×PC + 4.575×RSS。据此，我们可通过湿滤饼热值（calorific value of moist cake, CVmc）、湿滤饼重量（weight of moist cake, WMC）、甘蔗锤度（Pol cane, PC）以及甘蔗还原糖（RSS）计算得到总可回收糖分。该改进模型将湿滤饼热值（可反映纤维的生物能源潜能）与湿滤饼重量（可表征甘蔗纤维含量）两项参数纳入总可回收糖分的估算体系，同时保留了原有的甘蔗锤度与甘蔗还原糖两项影响因素。经测算，本改进模型得到的总可回收糖分估算值较CONSECANA原模型高出11.08%。
