Sweet sorghum is a potential complementary crop for ethanol production in Brazil, United States and India. Since, phenols are playing inhibitory role in the process of ethanol production from extracted juice from sweet sorghum stalks, it's removal from juice is necessary for better ethanol yield. The aim of this research was to evaluate the use of magnesium oxide and calcium hydroxide as coagulant agents in different pH levels in the juice treatment. The experiment was arranged in a split-plot statistical design. Main treatments corresponded to the different coagulants and secondary treatments were the pH levels (6.0 and 7.0). Analysis of coagulant volume, juice pH, settling rate and sludge volume were performed during the decantation process. Clarified juice was analyzed as Brix, pH, ashes, phenolic compounds and starch. The use of magnesium oxide resulted in lower sludge volume, phenolic compounds and ashes. The use of calcium hydroxide decreased starch content, whereas clarification at pH 7.0 promoted higher sludge volume. Treating juice with magnesium oxide improved decantation dynamics of the process and clarified juice quality.

Orange juice consumption can promote lower levels of oxidative stress and inflammation due to the antioxidant activity of citrus flavonoids and carotenoids. In addition, red-fleshed sweet orange juice (red orange juice) also contains lycopene. This study investigated the effects of red orange juice consumption on risk factors for metabolic syndrome. Volunteers consumed red orange juice daily for 8 weeks, with clinical and biochemical assessments performed at baseline and on the final day. There was no change in the abdominal obesity, but low-density lipoprotein cholesterol, C-reactive protein decreased, while there was an increase of the antioxidant activity in serum after red orange juice consumption. Insulin resistance and systolic blood pressure were reduced in normal-weight volunteers, while diastolic blood pressure decreased in overweight volunteers after intervention. Red orange juice showed anti-inflammatory, antioxidant, and lipid-lowering properties that may prevent the development of metabolic syndrome.
