UNLABELLED
Ellis, a representative for "homology of medicine and food", can be used to produce pigment and edible oil. Here, aqueous enzymatic extraction (AEE) combined with puffing pre-treatment was explored to prepare oil from gardenia seeds. Both wet-heating puffing (WP) at 90 °C and dry-heating puffing (DP) at 1.0 MPa facilitated the release of free oil by AEE, resulting in the highest free oil yields (FOY) of 21.8% and 23.2% within 3 h, much higher than that of un-puffed group. Additionally, active crocin and geniposide were also completely released. The FOY obtained was much higher than mechanical pressing method (10.44%), and close to solvent extraction (25.45%). Microstructure analysis indicated that gardenia seeds expanded by dry-heating puffing (1.0 MPa) had a larger, rougher surface and porous structure than other groups. Overall, AEE coupled with puffing pre-treatment developed is an eco-friendly extraction technology with high efficiency that can be employed to oil preparation.

未标注
“药食同源”的栀子可用于生产色素和食用油。在此，探索了水酶法提取（AEE）结合膨化预处理从栀子籽中制备油脂。90℃的湿热膨化（WP）和1.0MPa的干热膨化（DP）均促进了水酶法提取中游离油脂的释放，在3小时内游离油脂得率（FOY）最高分别达到21.8%和23.2%，远高于未膨化组。此外，活性藏红花素和栀子苷也完全释放出来。所获得的游离油脂得率远高于机械压榨法（10.44%），并接近溶剂萃取法（25.45%）。微观结构分析表明，经1.0MPa干热膨化的栀子籽比其他组具有更大、更粗糙的表面和多孔结构。总体而言，所开发的水酶法提取结合膨化预处理是一种高效的环保提取技术，可用于油脂制备。
