Interpretive Summary: This investigation aims to compare the encapsulation of sugar cane bagasse phenolic compounds using glandless cottonseed meal protein (GCSMP) and maltodextrin (MD), as well as the shelf-life stability. Sugarcane bagasse was analyzed to compare the antioxidant activity and total phenolic compounds of fresh extracts and encapsulated samples. The total phenolic content (TPC), antioxidant activity, and shelf-life stability of fresh and microencapsulated TPC were analyzed. Sugarcane bagasse showed high antioxidant activity, which remained stable after 30 days of storage at 4oC. The best encapsulation process was obtained when using encapsulating agents with a mixture of GCSMP and MD. The TPC and antioxidants activity of encapsulated phenolic compounds was stable at temperature up to 100°C for to 14 days.

Technical Abstract: This investigation aims to compare the microencapsulation efficiency of glandless cottonseed meal protein (GCSMP) and maltodextrin (MD), as well as the shelf-life stability of the microencapsulated sugar cane bagasse phenolic compounds. Sugarcane bagasse was analyzed to compare the antioxidant activity and total phenolic compounds of fresh extracts and microencapsulated samples. The total phenolic content (TPC), antioxidant activity, and shelf-life stability of fresh and microencapsulated TPC were analyzed. Sugarcane bagasse showed high antioxidant activity, which remained stable after 30 days of storage at 4oC. The best microencapsulation process was obtained when using encapsulating agents with ratios of 63.6% MD/ 36.4% GCSMP. The encapsulation efficiency (EE) was affected at P < 0.05 by the encapsulating agents' ratio however not at P > 0.05 by the spray-drying temperature. The different ratios of microencapsulation agents for MD and GCSMP P > 0.05 did not affect the total phenolic content (TPC) in the microcapsules. On the other hand, the microencapsulating agents' ratio resulted in P < 0.05, affected the antioxidant activity in the microcapsules. Spray-drying at P > 0.05, did not decrease TPC of the microencapsulated samples. The TPC of microencapsulated phenolic compounds was stable at temperature up to 100°C for to 14 days. GCSMP containing microcapsules showed a corrugated surface compared to a more homogenized surface of MD. The resulted corrugated structure explains the higher EE showed by the GCSMP.
