Juice Processing Effects On Small Scale Not From Concentrate Rabbiteye Blueberry Juice Production: The Evaluation Of Juice Recovery And Identification Of Anthocyanins And Anthocyanidins Through Processing Steps, Rebecca Elaine Stein-Chisholm

LSU Master's Theses

The order and combination of juicing steps can change a blueberry’s bioactive phytochemicals and effect juice recovery. In addition to physical treatments such as pressing, recovery is also affected by heat and enzymes steps. Not optimizing juicing methods affect juice quality and leave many bioactive components in the press cake. To evaluate pre-press treatments, southern highbush and rabbiteye blueberries were individually pressed in a bench top press at varying temperatures. The temperature treatments included fresh, thawed, frozen and heating to 95 °C. Two pectinase enzymes, Rohapect 10L and Pectinex BEXXL, were individually used to assess impact on juice extraction.
