Extracts rich in anthocyanin compounds were obtained from haskap berry pulp paste using supercritical carbon dioxide (scCO₂) and water as co-solvent. The extraction conditions including pressure, temperature, and amount of water were further optimized by Box-Behnken design. The highest total anthocyanins (TA) yield of 52.7% was achieved at 45 MPa, 65 °C, 5.4 g water to 3.2 g berry pulp paste, 15 min static and 20 min dynamic time. Different combinations of water and ethanol as co-solvent did not significantly affect the TA yield. Furthermore, similar anthocyanin extraction yields were obtained in the case of the pulp paste and rehydrated freeze-dried berry pulp powder, which indicates that freeze drying pretreatment is not required prior to scCO₂ extraction. Compared with conventional extraction, the use of scCO₂ and water as co-solvent offered higher anthocyanin extraction efficiency (52.7% versus 38.3%) with improved antioxidant activity (89.8% versus 72.2%).

使用超临界二氧化碳（scCO ₂）和水作为助溶剂，从Haskap浆果浆糊中获得了富含花色苷化合物的提取物。通过Box-Behnken设计进一步优化了萃取条件，包括压力，温度和水量。在45 MPa，65°C，5.4克水至3.2克浆果果肉糊，15分钟静态和20分钟动态时间的条件下，最高总花色苷（TA）产率为52.7％。水和乙醇作为助溶剂的不同组合不会显着影响TA的收率。此外，在果肉糊和再水合的冷冻干燥的浆果果肉粉的情况下，获得了相似的花色苷提取率，这表明在scCO ₂之前不需要进行冷冻干燥预处理。萃取。与常规提取相比，使用scCO ₂和水作为共溶剂可提供更高的花色苷提取效率（52.7％对38.3％）和更高的抗氧化活性（89.8％对72.2％）。
