Abstract: This study aimed to optimize the extraction and clarification conditions of golden jujube juice. The results indicated that the highest extraction efficiency was obtained after 200 min of extraction at 50 ℃ and a material/liquid ratio of 1:10 (g/mL). Golden jujube juice obtained after hydrolysis at 45 ℃ for 120 min with a complex enzyme added at a level of 0.015% (V/V) showed the biggest transmittance, a clear and transparent appearance and a strong aroma. The best decolorization results were achieved after 180 min of oscillation at 25 ℃ and 120 r/min in the presence of LX-10C macroporous resin at an addition level of 7.0 g/100 mL.

Key words: golden jujube, extraction, enzymolysis, decolorization, technology
