Embodiment 1

[0063] Manufacture of adsorbents (konjac powder with added glycerol and activated carbon)

[0064] Fully mix 16g of refined konjac powder with 16g of activated carbon with an average particle diameter of 30 μm, add little by little to 750ml of 30°C 5% (weight) glycerin aqueous solution, pay attention to make it not lumpy, stir while stirring Heat for about 5 minutes. After bubbling and bubbling, switch to medium heat and continue stirring for 7-8 minutes, then cool to 40°C. Fully grind 0.64g of CaO with a mortar, dissolve it in 50ml of hot water at 40°C, then add it to the above food, knead it quickly, put it into the mold, press it with your fingers, and remove the air inside to make it Reach homogenization, then put into hot water together with mould, heat about 5 minutes, after taking out from mould, continue heating in 1000ml 5% (weight) glycerol aqueous solution again 25 minutes, make it solidify completely, 650 g of konjac powder containing activated carbon was obtaine...

Embodiment 2

[0066] Manufacture of adsorbent (konjac powder with glycerol added, frozen, activated carbon)

[0067] 500 g of konjac powder containing glycerin and activated carbon produced in the same manner as in Example 1 was frozen in liquid nitrogen (-196° C.), and then thawed in 40° C. warm water. Expose it to running water to remove the glycerol and remove the color, finely chop about 1mm 3 , Obtain the adsorbent of the present invention (adding glycerol, through freezing treatment, konjac powder containing activated carbon).

Embodiment 3

[0069] Manufacture of adsorbent (konjac powder with added glycerin, dried, activated carbon)

[0070] The adsorbent prepared in 200g embodiment 1 is put into desiccator and further fully dried, obtains adsorbent of the present invention (adding glycerol, drying process, konjac powder containing activated carbon).

Abstract

An adsorbent is provided by performing freezing treatment after covering an adsorbent body such as activated charcoal with a gel-like substance such as bivalent metallic salts of high molecular polycarboxylic acid, bean curd, jelly, konnyaku, agar, perilla, gelidium jelly and chitosan oxalate gel, or removing a frost damage preventive substance such as glycerol after covering the adsorbent body with the above gel-like substance which contains the frost damage preventive substance. The adsorbent is made to contact directly with food and the like or dosed directly to a digestive system, whereby it is possible to highly efficiently adsorb and remove food additives, fodder additives, pesticides, substances causing sitotoxism, allergen, heavy metals or highly toxic organic compounds and the like which adhere to or are contained in food and the like or which are existent in a digestive system, surplus nutrients existent in a digestive system, oligomer and additives contained in liquors, intermediate metabolic substances of alcohol generated in a digestive system after taking of spirits, harmful substances such as hydroperoxide of unsaturated fatty acid in fats and oils, and odor ingredient such as fish odor.

Description

field of invention [0001] The present invention relates to a novel adsorbent for adsorbing and removing harmful substances, and more specifically, the present invention relates to an adsorbent composed of an adsorbent coated with a gel-like substance. Background of the invention [0002] Activated carbon has a large specific surface area and high adsorption capacity, and is widely used in various applications as a typical adsorbent. However, when activated carbon is used as medicinal carbon to directly administer drugs to the digestive system in order to adsorb and remove substances that cause self-poisoning and drug poisoning, problems such as constipation may occur. In addition, if activated carbon is mixed into food, there will be a foreign body sensation when eating, and the food will be polluted into black. In addition, it is now known that animal cells can adsorb microparticle activated carbon to proteins or glycoproteins on the outer layer of cell membranes. When mic...
