Evaporator juices and syrups were carefully stored to prevent further chemical degradation reactions and/or microbial growth. Each sample was first collected in a large (250 mL) container, and then, _25 mL was immediately poured into a 50 mL container. The two containers were immediately placed in dry ice before transportation to the Southern Regional Research Center laboratory in New Orleans, LA. The samples were stored in a -80 C laboratory freezer until laboratory analyses. Glucose, fructose, and sucrose concentrations were measured in juice from the small containers, usually the next day .All other analyses were measured in juice from the large containers.
