Cassava Bagasse Valorization: Carotenoid Extraction

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cassava bagasse was obtained from the agroindustry Fecularia Machado (Sombrio county, Santa Catarina state, southern Brazil) from roots harvested in 2014/2015. Bagasse was produced as a solid by-product during the extraction of cassava starch. Polysorbate 80 (Tween 80) and polysorbate 20 (Tween 20) were purchased from Vetec (Rio de Janeiro, Brazil). PIC Química (São Paulo, Brazil) kindly donated caprylic/capric triglyceride (Miglyol 812 N), a medium chain triglyceride (MCT), and corn oil was bought from a local supermarket. β-carotene (BC, ≥ 97% purity grade) and 2, 2-diphenyl-2-picrylhydrazyl (DPPH) were obtained from Sigma-Aldrich (St. Louis, MO) and methanol, acetonitrile, and acetone (HPLC grade) from Tedia Company (Fairfield, OH) All other chemicals were analytical grade reagents.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
