“…In addition, the film solution is more uniform and smooth with high rapid heating . Nowadays, ultrasonic/microwave‐assisted treatment is widely used in the extraction and synthesis of components, and it is beneficial for improving the properties of edible films . However, the study of modified microcrystalline corn straw cellulose (MMCSC) by ultrasonic/microwave‐assisted treatment and the effect on the properties of corn distarch phosphate (CDP)‐based films has not been reported.…”

Ultrasonic‐microwave synergistic extraction (UMSE) was used to extract from Morchella conica polysaccharide (MCP). The effect of three independent variables (microwave power, ratio of water volume to raw material weight (W/M ratio), extraction time) on extraction yield was optimized using response surface methodology with a Box–Behnken design. The high R2 values (>.966) demonstrated the response and independent variables predicted by polynomial model were fitted. The optimal conditions for MCP extraction were microwave power of 210.61 W, W/M ratio of 41.07:1, and extraction time of 126.98 s. Under these conditions, the experimental yield was 7.53 ± 0.17%. By comparison of ultrasound assistant extraction (UAE) and microwave assistant extraction (MAE), the extraction efficiency of UMSE is the highest. Practical applications Morchella conica is a species of mushroom contained with amount of bioactive polysaccharide. Novel extraction technique UMSE was applied to extract MCP because the high synergistic energy promotes cell disruption and MCP release. Compared with the traditional extraction technology, UMSE requires shorter time and higher efficiency. These effects make UMSE economic to gain bioactive MCP. Thus, the application of UMSE can be useful for improvement on industrial extraction processes of food and natural products.

“…The approach of UMSE for simultaneous extraction of larch arabinogalactan and taxifolin was operated at an UWave‐1000 ultrasonic microwave synergistic extracting apparatus (XTrust, Shanghai, China) as presented and described in a previous study (Liu, Gu, & Yang, ). The size of the oven interior cavity was 570 × 510 × 520 mm.…”

Double experimental designs, Plackett–Burman design coupled with Box–Behnken design, were used to optimize the simultaneous extraction process of arabinogalactan and taxifolin from Larix gmelinii by ultrasonic microwave synergistic extraction (UMSE) method. The optimal extraction conditions were determined with the extraction yields of 223.40 ± 7.82 mg/g for larch arabinogalactan and 125.02 ± 5.30 mg/g for taxifolin. Compared to conventional methods, UMSE method showed the merits of higher extraction efficiency, saving time, and energy. The molar ratio of galactose to arabinose is found to be 6:1 through the monosaccharide composition analysis of larch arabinogalactan. The obtained taxifolin structure was identified by mass spectrometry, Fourier transform infrared spectroscopy, and nuclear magnetic resonance. Interestingly, larch arabinogalactan and taxifolin showed completely opposite influences on α‐amylase, α‐glycosidase, and pancreatic lipase; it was inferred that larch arabinogalactan could act as an inhibitor while taxifolin as an accelerator. Practical applications In this study, response surface methodology of Plackett–Burman design and Box–Behnken design performed well to obtain the optimal conditions and satisfactory extraction yields for the extraction of arabinogalactan and taxifolin from Larix gmelinii by ultrasonic microwave synergistic extraction method, which could be a good paradigm for the efficient isolation of bioactive substances from plant matrix in the field of separation science. Meanwhile, the results from the evaluation of the effects of two target compounds on activities of α‐amylase, α‐glycosidase, and pancreatic lipase in vitro revealed that larch arabinogalactan and taxifolin enjoyed the completely opposite influences on the three digestive enzymes, namely larch arabinogalactan could act as an inhibitor while taxifolin an accelerator. These results will facilitate the application of larch arabinogalactan and taxifolin in the food and pharmaceutical industries.
