ABSTRACT:
TECHNICAL FIELD
This invention relates to a novel adsorbent to be used in agents for the removal of harmful substances by adsorption. More particularly, the invention relates to an adsorbent which is formed by coating an adsorption basis with a gel-like substance.
BACKGROUND ART
The active carbon possesses a large specific surface area and exhibits a great ability to effect adsorption and finds utility as a representative adsorbent in various applications. When the active carbon is directly ingested into the digestive system as a medicinal carbon for the purpose of removing by adsorption such substances as induce autointoxication, medicinal poisoning, etc. however, it is liable to do harm by causing constipation. When an effort is made to mingle the active carbon with a foodstuff and ingest the mixture into the digestive system, it is at a disadvantage in imparting an unpleasant sensation to the palate and smearing the foodstuff in a blackish tint. It is also known that in the animal cell, the active carbon in a finely divided state is adsorbed on the protein or sugar protein in the outer layer of the cell membrane. When the active carbon in the finely divided state is directly ingested into the digestive system as an agent for the removal of a harmful substance by adsorption, it is suspected that part thereof persists in a state adsorbed on the cells in the digestive system with fastness such that thorough elimination thereof from the digestive system may be extremely difficult.
With a view to solving this problem, adsorbents formed by coating active carbon with water-insoluble mannan such as konjak or with a cross-linked polymer such as calcium alginate have been proposed (JP-A-55-95,611 and JP-A-04-210,239). Since these adsorbents result from forming a surface coat on the particles of active carbon, they suffer from such problems as inducing a decrease in the surface area and impeding ample manifestation of the ability of adsorption inherent in the active carbon.
This invention has been created in the light of the problem encountered by the prior art as described above. It has for an object thereof the provision of an adsorbent which keeps intact the ability of adsorption inherent in the adsorption basis such as of active carbon and, on being brought into direct contact with foodstuffs or ingested directly into the digestive system, effects highly efficiently the removal by adsorption of such harmful substances as are suffered to adhere to or mingle into the foodstuffs or suffered to occur in the digestive system.
DISCLOSURE OF THE INVENTION
The object mentioned above is accomplished by this invention providing an adsorbent which is formed by coating an adsorption basis with a gel-like substance and subsequently subjecting the coated basis to a freezing treatment.
The object is further accomplished by this invention providing an adsorbent which is formed by coating an adsorption basis with a gel-like substance already containing a frost damage preventing substance and subsequently depriving the coated basis partly or wholly of the frost damage preventing substance.
This invention further concerns the adsorbent, wherein the frost damage preventing substance mentioned above is glycerin.
This invention further concerns the adsorbent, wherein the adsorption basis mentioned above is a carbonaceous material possessing the ability to effect adsorption.
This invention further concerns the adsorbent, wherein the carbonaceous material possessing the ability to effect adsorption is active carbon or charcoal.
This invention further concerns the adsorbent, wherein the gel-like substance mentioned above is the divalent metallic salt of a macromolecular polycarboxylic acid.
This invention further concerns the adsorbent, wherein the divalent metallic salt of the macromolecular polycarboxylic acid mentioned above is calcium alginate.
This invention further concerns the adsorbent, wherein the gel-like substance mentioned above is soybean curd, jelly, konjak, agar, perilla, gelidium jelly, or chitosanoxalic acid salt gel.
This invention further concerns the adsorbent which is formed by drying the adsorbent mentioned above.
This invention further concerns the adsorbent which comprises an adsorbent moiety formed by coating an adsorption basis with a first gel-like substance and a second gel-like substance moiety.
This invention further concerns the adsorbent which is formed by seasoning either the adsorbent moiety mentioned above or the second gel-like substance moiety mentioned above.
This invention further concerns the adsorbent wherein the adsorbent moiety mentioned above comprises any of the adsorbents mentioned above.
This invention further concerns an agent for the removal by adsorption of a harmful substance, which agent comprises any of the adsorbents mentioned above.
This invention further concerns an agent for removal by adsorption of a harmful substance, wherein the harmful substance mentioned above is a food additive, a feed additive, an agricultural pesticide, a food poisoning substance, allergen, a heavy metal, or a strongly poisonous organic compound which is suffered to adhere to or mingle in a foodstuff or an animal feed or assimilated into the digestive system.
This invention further concerns the agent mentioned above for removal by adsorption of a harmful substance, wherein the feed additive mentioned above is an antibiotic substance, a synthetic antibacterial agent, or a hormone.
This invention further concerns the agent mentioned above for removal by adsorption of the harmful substance, wherein the food poisoning substance mentioned above is exotoxins, autotoxins, or a harmful chemical substance.
This invention further concerns the agent for removal by adsorption of a harmful substance, wherein the agent mentioned above is formed of the adsorbent mentioned above and the harmful substance mentioned above is formed of an antibiotic substance which has either undergone oral ingestion or acted on the intestinal bacteria.
This invention further concerns the agent for removal by adsorption of a surplus nutrient assimilated in the digestive system, wherein the agent mentioned above is formed of the adsorbent mentioned above.
This invention further concerns the agent for removal by adsorption of the metabolite of alcohol formed in the digestive system in consequence of the assimilation of the alcohol, wherein the agent mentioned above is formed of the adsorbent mentioned above.
This invention further concerns the agent for removal by adsorption of the hydroperoxide of an unsaturated fatty acid, wherein the agent mentioned above is the adsorbent mentioned above.
This invention further concerns a deodorant formed of the adsorbent mentioned above.
This invention further concerns a processed foodstuff or animal feed incorporating therein the adsorbent mentioned above in an amount in the range of 0.01-6 wt. %.
This invention further concerns the processed foodstuff mentioned above which is a dairy product, a product of fish paste, a processed fish or shellfish, a processed meat, processed beans, processed vegetables, a processed potato, a processed cereal, a sweetener, oil and fat, or a cake.
It is considered that when the adsorbent of this invention is formed by coating an adsorption basis with a gel-like substance and then subjecting the coated basis to a freezing treatment, this adsorbent is enabled to keep intact the ability to effect adsorption possessed inherently by the adsorption basis because the moisture in the gel-like substance forming the coat is coagulated and is consequently allowed to form in the coat such minute pores as have a larger diameter than the pores which would be formed solely by cross-linkage.
It is considered that when the adsorbent is formed by coating the adsorption basis with the gel-like substance already containing a frost preventing substance and then depriving the coated basis of the frost preventing substance, this adsorbent is enabled to manifest the same effect as mentioned above because the procedure so employed produces similar minute pores in t
