Abstract:

Juvenile fruit of golden pomelo was studied to efficiently extract its total dietary fiber through the single factor experiment and response surface analysis. The effects of ultrasonic time, solid-liquid ratio and oscillating temperature on the yield of juvenile fruit total dietary fiber were discussed. The extracted total dietary fiber was added into protein bars, and the content of total dietary fiber in protein bars was determined. Finally, the sensory evaluation and texture changes of protein bars stored at different temperatures were investigated. The results showed that the highest extraction rate of (56.3±1.0) % was achieved at 1 g∶10 mL of the solid to liquid ratio for 55 min ultrasonication under 35 ℃ oscillation temperature after 3 times of extraction. By sensory evaluation, the optimal mass fraction of total dietary fiber added was 4%. When the protein bars were stored at different temperatures, the hardness, viscosity and color increased, flavor deteriorated and sensory evaluation score decreased with the increase of temperature or duration.
