The present disclosure provides an ultrasonic-microwave synergistic extraction method of total saponins in beautiful millettia root, comprising the following steps: S1, material treatment, S2, cold soaking, S3 enzymatic hydrolysis, S4 extract extraction, and S5 ultrasonic-microwave synergistic extraction. The extraction method of the present disclosure extracts relatively high content of total saponins, and has relatively high yield of saponins and low content of impurities, and each step acts synergistically to solve the problems of relatively low total saponin content, more impumayrities and bubbling in the extraction process.

A method for extracting compounds from plant material utilizing terpenes as a solvent is described. The invention includes the excitation of the plant material and terpene solvent with microwave, ultrasound, heat input, and physical agitation or combinations thereof. The invention particularly covers the process as it relates to the extraction of THC and CBD and their derivatives from cannabis and hemp for the use in products for medical and recreational use. The combinations of terpene saturant, plant material strain and process variables can be tuned in order to dial in the final resultant product for several variables including but not limited to terpene content, THC or CBD potency, ratios of THC or CBD and their derivatives, or flavor profile.

Soil contamination by heavy metals constitutes an important environmental problem, whereas field applicability of existing remediation technologies has encountered numerous obstacles, such as long operation time, high chemical cost, large energy consumption, secondary pollution, and soil degradation. A design and demonstration of a method is provided which is based on asymmetrical alternating current electrochemistry (AACE) that achieves high degrees of contaminant removal for different heavy metals (Cu, Pb, Cd) at different initial concentrations (from 100 to 10,000 ppm), all reaching corresponding regulation levels for residential scenario after rational treatment time (from 30 min to 6 h). No excessive nutrient loss in treated soil was observed and no secondary toxic product was produced. Long-term experiment and plant assay showed the high sustainability of the method and its feasibility for agricultural use.

The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.

The invention refers to a distillation apparatus (100) for extraction of volatile components from biological material (50), especially from plants, comprising a housing (10) defining a sample chamber (S), a drum (30) arranged in the sample chamber (S), the drum (30) defining a receiving chamber (R) for receiving the biological material (50), and at least one microwave generator (70) for irradiating the biological material (50) with microwave radiation when received in the drum (30); wherein the drum (30) is rotatably arranged in the sample chamber (S) about a rotation axis (H) which is oriented substantially horizontally.

The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.

A collecting device includes a stage configured to place a substrate. A magnetic field generating unit holds, by a magnetic field, a first liquid containing a magnetic fluid and a collecting liquid to bring the first liquid into contact with at least an end portion of the substrate. A collecting unit collects the first liquid from the magnetic field generating unit. A separating unit separates the collecting liquid from the first liquid.
