Abstract

The harvest of sweet sorghum has been studied in several countries because it increases the costs. However, it could decrease the quality of raw material destined to ethanol production. Therefore, the goal of this study was to analyse the quality of the raw material coming from two different sorghum cutting types and at different processing times. At 120 days after sowing, the harvest was carried out manually, the sorghum being chopped into 20-cm billets, and a portion of the stalks were shredded in a forage chopper, resulting in particles of 2–3 cm in diameter. The broth was extracted through a hydraulic press at 0, 6, 12 and 24 h after cutting and characterized. We concluded that the billets was the most suitable for the sorghum, since there was less deterioration of the plant in relation to the cut into forage form and the plant processing must occur within 6 h for the best possible use of the material.
