The purpose of the present invention is to provide a water-soluble polysaccharide which is less expensive and enables the production of an acidic protein food or drink, said acidic protein food or drink being stable in an acidic pH range at the isoelectric point of protein or higher, even by using a starting material such as a root vegetable. A water-soluble polysaccharide, which is extracted from a starting material derived from a root vegetable in a wet state with hot water under acidic conditions of pH 2.7-3.7, can well stabilize an acidic protein food or drink in a pH range at the isoelectric point of protein or higher.

Disclosed is a continuous process for the purification of steviol glycosides such as Rebaudioside D and/or Rebaudioside M extracted from the dried stevia leaves or extracted from a fermentation broth 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.

Described herein is a corn protein product comprising greater than about 20% corn protein on a dry weight basis and a free sulfite concentration of less than 150 ppm on an as-is basis. Also disclosed herein is a method to obtain this corn protein product including the steps of providing a protein-rich stream derived from a wet corn milling operation, wherein the protein-rich stream comprises greater than 20% corn protein on a dry weight basis, and treating the protein-rich stream with an oxidant, preferably hydrogen peroxide.

Disclosed is a method for removing benzo[α]pyrene from a liposoluble natural extract. The method of the present invention comprises adding a suitable solvent to a crude natural extract product so as to obtain a mixed material; heating the mixed material, stirring until uniform, cooling and layering, and then separating the upper layer from the lower layer so as to obtain a precipitate and a filtrate; washing the precipitate with a small amount of a solvent so as to obtain a washed product and a washing solution; removing the solvent from the washed product at a low temperature so as to obtain a finished product; and directly recycling the filtrate and the washing solution as solvents. The present method achieves the purification of the crude natural extract product and the removal of benzo[α]pyrene in one step, and is a novel method which is simple, highly efficient, feasible and easy for industrial applications.

An oyster peptide with an effect of improving sexual function and a preparation method thereof are provided, the oyster peptide at least includes peptide segments RI, IR and VR in its composition. Based on a mass of the oyster peptide, a content of the RI is ≥3.60 mg/100 g, a content of the IR is ≥7.60 mg/100 g, and a content of the VR is ≥6.50 mg/100 g.

The present invention features methods of extracting amylase trypsin inhibitors (ATIs) from processed and unprocessed foodstuff, determining bioactivity of ATIs, quantifying the amount of ATIs in a foodstuff, and reducing the content of ATIs in a foodstuff.

The present invention relates to a method for the preparation of a coleoptera oil enriched with vitamin D3 including a light treatment step in which at least one light source emits ultraviolet rays in the direction of said coleoptera oil.

Methods for separating lean and fat from beef or other meats and the separation apparatus are disclosed. The methods use microbiocidal fluids to reduce or eliminate possible sources of contamination.

The present invention relates to a composition for preventing, alleviating, or treating allergic skin diseases comprising, as an active ingredient, an extract of Gardenia fruit from which pigment is removed, and since the extract of Gardenia fruit from which pigment is removed is more effective for allergic skin diseases compared to an extract of Gardenia fruit from which pigment is not removed, the composition can be very advantageously used for allergic skin diseases, in particular, atopic dermatitis.
