The invention relates to a method for extracting mycotoxins from grain and other food products or from feed and its subsequent quantification. Fields of application are the food industry, the animal feed industry or biotechnology. The objective of the present invention was to develop an extraction method with which it is possible to uniformly extract mycotoxins with different dissolving properties. It was found that with the aid of aqueous, buffered naphthyl and/or phenyl compounds or their heterocyclical analogues, both hydrophobic and hydrophilic mycotoxins can be extracted. The method is characterized in that the buffered solutions of naphthyl and/or phenyl compounds and/or their heterocyclical analogues, which carry at least one sulphonic acid or at least one carbonate acid group, are brought into contact with the grain or other food products or animal feed, the aqueous solution is separated and the content of the extracted mycotoxins in the solution is determined.

Treatment of dried perennial ryegrass with aqueous citrate ion from sodium citrate chelates calcium from the grass which improves extracting juice from the grass. Addition of ascorbic acid to the aqueous solution decreases enzymatic browning of the juice. The juice is centrifuged and filtered. Microscopic examination of the centrifuged and filtered juice that has been stained with methylene blue demonstrates a cellulose content less than extracted wheat grass. Processing the dried perennial ryegrass can be achieved without electricity. Extraction of nutrients from perennial ryegrass may help alleviate world food shortages and may promote peace.

A heater is fluidically connected to the fluid inlet. The heater is configured to increase a temperature of the fluid.

Embodiments herein relate to a human edible or drinkable product comprising an enhanced kava extract, wherein the enhanced kava extract comprises a kava product extracted using a material comprising CO2 and/or ethanol extraction method from a selected part of a kava plant and containing 50% or more of a kavalactone as measured by HPLC, wherein the kava plant is not a wild type kava such that the kava product is safe for human consumption, wherein the composition further comprises an additive comprising a tetrahydrocannabinol extract, a cannabidiol extract, a hemp extract or combinations thereof. In one embodiment, the enhanced kava extract comprises a kava product extracted using a non-organic solvent.

Methods to produce cannabis-related products derived from a cannabis oil extract subjected to a two-step supercritical carbon dioxide separation process are described. Cannabis terpenes are separated from cannabis plant material at a relatively lower temperature and pressure than the cannabis oil which may then be distilled and/or mixed with an ingredient to produce a multifunctional composition. Methods to produce medicinal and recreational cannabis and insect-related products are described.

Disclosed herein is a method of maintaining corn protein yield during extraction and managing stickiness and viscosity comprising obtaining a corn material having a corn protein content and washing the corn material to remove non-protein components with an ethanol-water solvent comprising at least 85 wt % ethanol to obtain a corn protein isolate, wherein the loss of corn protein content during extraction is less than 10% of total corn protein.

The disclosure discloses stabilized rice aleurone and a preparation method, using the technology of classifying a rice aleurone layer by a tangential injection airflow impeller classifier combined with an ultrasonic vibrating screen for the first time, and simultaneously uses steam treatment coupled with thermal enzyme inactivation by drum drying as a stabilization method to prepare the stabilized rice aleurone for the first time. The drum drying equipment realizes the two purposes of enzyme inactivation and drying, and the method has the advantages of short process flow, simple equipment, high utilization rate, small floor space, low investment, low energy consumption and no pollution, and is suitable for industrial promotion. The stabilized rice aleurone has high nutritional value, is rich in functional ingredients, and can be used as a raw material for functional food development in industrial production and food applications.

A process for preparing fish bone powder according to this invention generally comprising at least 4 steps: pre-heating, removing of impurity, drying and milling to derive a calcium-rich bone powder product that contains calcium in the range of 18-22 g/100 g of the fmal product. In addition, the bone powder particle size obtained is less than 100 microns and contains high levels of protein, fat, and essential minerals, such as sodium and phosphorus. The source of bone can be obtained from any fishes, preferably from tuna.

Disclosed is a continuous process for the purification of steviol glycosides extracted from the dried stevia leaves using continuous simulated moving bed processes and nanofiltration without the addition of organic solvents to obtain a purified steviol product comprising sweet steviol glycosides. The sweet steviol glycosides can be used as substitutes for caloric sweeteners in beverages and in other food items.

The disclosure describes methods for the purification of protein-enriched extracts to provide concentrates and isolates and methods for incorporation of such materials into products. The purification methods are adapted for removal of one or more of ash, metal salts, alkaloids, particulates, heavy metals, and other impurities and/or contaminants from extracts, as well as modifying the sensory characteristics (e.g., odor, color, and/or taste characteristics) of extracts. The methods generally include diafiltration, treatment with functionalized resins, and supercritical extraction. A protein composition in the form of a concentrate or isolate is provided, the protein composition including RuBisCO, F2 fraction proteins, or combination thereof extracted from a plant of the Nicotiana species, wherein the protein composition is characterized by one or more of: an ash content of less than about 15% by weight; a nicotine content of less than about 10 ?g/g; and a heavy metal content of less than about 60 ?g/g.
