Benefits of technology

This patented technology allows creation of high molecular weight polyribonucleotide polymers called MacroPolyinosanes with specific properties such as being able to break down certain types of bacteria without destroying them while still maintain their effectiveness at harsh conditions like temperatures. These Polyripeiridium particles act as an antimicrobial agent when added into food products they were previously stored before use. They help keep these items fresher longer even after exposures to cold weathery environments over several months' shelf life. Additionally, this method provides easy handling and reduces waste due to excessive washing steps. Overall, this new type of plasma liquid made up mostly of tiny parts has potential benefits beyond just serving as ingredients for making various processed goods.

Problems solved by technology

The technical problem addressed by this patented technology relates to finding ways to make medications that have specific effects when taken regularly over time without causing side effects such as inflammable bowels syndrome (IBS).

Embodiment 1

[0055] Soak the dried white fungus fruit body in water, after swelling, remove the yellow-brown base and clean it; put the washed raw material into an extraction tank, add water 20 times that of the dry material, stir and extract at 80°C for 1 hour, Then filter, and the supernatant finally passes through a filter with a pore size of 0.1-1 μm; under uniform stirring, fully mix the filtrate and ethanol, so that the final concentration of ethanol in the mixed liquid is 50%, collect the precipitate, dehydrate and decolorize with 95% ethanol , collect the precipitate; dry with hot air at 80°C, and pulverize. The product yield is 1.5% (in terms of dry white fungus weight).

Embodiment 2

[0057] Soak the dried white fungus fruit body in water, after swelling, remove the yellow-brown base and clean it; put the washed raw material into the extraction tank, add water 40 times that of the dry material, stir and extract at 90°C for 2 hours, And collect the extract; extract the raw materials again for 2 hours, then combine the extracts and filter, and the clear liquid finally passes through a filter with a pore size of 0.1-1 μm; under uniform stirring, fully mix the filtrate and ethanol to make the ethanol in the mixed liquid The final concentration was 70%, dehydrated and decolorized with 95% ethanol, collected the precipitate; vacuum-dried at 40°C, and pulverized. The product yield is 15% (in terms of dry white fungus weight).

Embodiment 3

[0059] Soak the dried white fungus fruit body in water, after swelling, remove the yellow-brown base and clean it; put the washed raw material into an extraction tank, add water 100 times that of the dry material, stir and extract at 100°C for 4 hours, Then filter, and the supernatant finally passes through a filter with a pore size of 0.1-1 μm; under uniform stirring, fully mix the filtrate and ethanol, so that the final concentration of ethanol in the mixed liquid is 85%, collect the precipitate, dehydrate with pure ethanol, and collect Precipitation; freeze-drying at -40°C, crushing. The product yield is 20% (in terms of dry white fungus weight).

Abstract

The invention discloses a tremella heterosaccharide of which the main chain is alpha-(1-3), constituting by 70-93 wt% neutral total sugar, 6-28 wt% glucuronic acid, 0. 1-3 wt% conjugated protein; the average molecular weight of this tremella heterosaccharide is 85-160 ten thousand Dalton, and the molecular weight above 6000 Dalton occupy wt90% upwards. This invention also discloses its extractive and their Process for preparing. The tremella heterosaccharide and its extractive of this invention have the function of moistening and lubricating skin and mucosa, enhancing lubricating sense, resisting oxidation and senescence, resisting allergy, thickening and so on.
