Plant polysaccharide extract for moisturizing

The present invention relates to a plant polysaccharide extract for moisturizing; in particular to a polysaccharide extract obtained by appropriate extraction from plant seeds or plant seed coats.

A method for extracting plant seeds and extracts thereof, such as the Pseudoplastic yellow mustard gum method of the U.S. Patent No. 4,980,186, which discloses a method for extracting gum from yellow mustard seeds, comprising: First, the yellow mustard seeds are gradually subjected to extraction treatment with an aqueous solution of increasing temperature to obtain an extract solution.

Next, the extract solution of No. 4,980,186 is subjected to separation treatment in an appropriate mechanical separation manner to obtain an aqueous extract. At this time, the mechanical separation method includes a perforated centrifuge separation technique and a slitted centrifuge separation technique. The aqueous extract was appropriately treated in the form of precipitation and drying.

Many specific compounds (eg, polysaccharides or other compounds) present in various plant seeds may be of high economic value and require the removal of such highly economically valuable compounds from the plant seeds in order to avoid physical or chemical damage. The compound is then further processed to form a product of high economic value.

For example, polysaccharides or other compounds contained in various plant seeds can be applied or added to cosmetics or skin care products. However, compounds containing plant seeds need to be confirmed for their properties and economic value in order to understand how to extract and apply the compound. Therefore, there is currently a need in many plant seeds for the need to remove compounds of high economic value.

Further, the plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention can be made into various forms of products, such as powder products, but it is not intended to limit the scope of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the flow of a plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention. Referring to Fig. 1, a method for producing a plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention comprises a first step S1: preparing a plant seed or a plant seed coat in an appropriate manner, and storing the plant in an appropriate manner. Plant seeds or plant seed coats. In the preferred embodiment of the present invention, the plant seed or plant seed coat is a Rutaceae plant seed or plant seed coat, for example, comprising grapefruit, white grapefruit, etc., but it is not intended to limit the present invention.

Referring to FIG. 1 again, the method for producing a plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention comprises a second step S2: extracting from the plant seed or plant seed coat by aqueous solution extraction for a predetermined time, An extraction solution is obtained, and the extraction solution is a seed mucilage [seed mucilage]. In the preferred embodiment of the present invention, the extraction solution is obtained by cold water extraction, wherein the temperature of the cold water is lower than room temperature [for example, 25 ° C], but it is not intended to limit the present invention.

Referring to FIG. 1 again, the method for producing a plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention comprises a third step S3: obtaining a preliminary polysaccharide solution from the extraction solution by appropriate separation technique [separation] technique [preliminary polysaccharide liquid]. The preliminary polysaccharide solution of the preferred embodiment of the present invention is obtained by a centrifugation technique [e.g., a centrifuge device] and a filtration technique [e.g., a filtration device].

Referring to FIG. 1 again, the method for producing a plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention comprises a fourth step S4: preparing the preliminary polysaccharide solution into the polysaccharide extract. The polysaccharide extract of the preferred embodiment of the invention comprises at least one polysaccharide, but it is not intended to limit the invention.

Referring to FIG. 1 again, in the preferred embodiment of the present invention, the preliminary polysaccharide solution is processed by freeze drying or vacuum freeze drying to produce the polysaccharide extract. A polysaccharide product. At this time, the polysaccharide extract of the preferred embodiment of the present invention is a polysaccharide powder.

Fig. 2 is a schematic view showing the composition analysis of the polysaccharide composition of the plant polysaccharide extract for moisturizing according to a preferred embodiment of the present invention. For example, the plant seed or plant seed coat is a Rutaceae plant seed or a plant seed coat. Referring to Fig. 2, the polysaccharide of the polysaccharide extract of the preferred embodiment of the present invention is taken from grapefruit seed skin and composed of neutral sugar, which comprises rhammose and arabine. Neutral sugars such as galactose, glucose, mannose, and/or xylose.
