    Abstract: An absorbent pad that contains activated carbon to reduce confinement odor in a vacuum-packaged food product is provided. An embodiment of absorbent pad contains activated carbon and an antimicrobial agent that further reduces confinement odor by two mechanisms of action: reducing bacterial counts in the liquid purge that cause breakdown of carbohydrates and proteins in food products; and trapping of confinement odor-causing breakdown products by the activated carbon. The absorbent body in the absorbent pad actively draws in liquid purge and dissolved volatile breakdown products in the vacuum package that produce confinement odor, which produces greater and more rapid contact of odor-causing compounds with the activated carbon.

  • Publication number: 20130251883
    Abstract: The present invention discloses a method of manufacturing porous granules, a porous granule obtained by the method, a lipid-containing granule and a method of manufacturing thereof, and a food containing the lipid-containing granules and a method of manufacturing thereof. The porous granule of the present invention is bigger than the granule manufactured by the spray drying method, has high solubility, is easily obtained (porous structure can be easily formed), and has enough hardness. In addition, drying time and drying cost can be reduced because an amount of water to be dried can be reduced. The porous granule can be obtained by mixing a powder whose solubility is at most 100 g per 100 mL of water at 20° C., with water and drying a mixture under reduced pressure to obtain the porous granules having loose bulk density of at least 0.30 g/mL, having porous structure, and capable of absorbing lipids.

  • Publication number: 20130244871
    Abstract: A mixture for producing a fiber or a molded part contains at least one polymer solution, in particular a cellulose solution, and an adsorbing agent. The mixture includes a removable resisting agent for the adsorbing agent. The polymer solution also can be used as a resisting agent. In order to produce a fiber or a molded part, an adsorbing agent is mixed with a polymer solution, in particular a cellulose solution, where a removable resisting agent is applied to the adsorbing agent before or during the mixing process and wherein the resisting agent is removed after the fiber has been spun or after the molded part has been molded. Alternatively or in addition thereto, a method for producing a fiber or a molded part, an adsorbing agent, in particular activated charcoal, is mixed with a polymer solution, in particular a cellulose solution.

  • Patent number: 8535625
    Abstract: An adsorbent contains a carbohydrate having an ether linkage. Alternatively, an adsorbent contains a carbohydrate having a cross-linkage formation produced by a dehydration reaction using a strong acid. In collection of a precious metal using the adsorbent, the adsorbent selectively adsorbs a precious metal dissolved in a solution.

  • Patent number: 8501663
    Abstract: In the present, a procedure of obtaining adsorbent from a waste material and its use are disclosed. This invention provides a natural waste material, specifically avocado seed, its preparation and use for the filling of columns used in the elimination of contaminants present in wastewater. The particles have an irregular shape and variable size for filling columns of different diameter and length. The adsorbent has the sufficient hardness for avoiding a particle collapse. The material does not rot, is re-generable and ecological. In the present invention the preparation of the adsorbent, its pre-activation, carbonization and application to eliminate the color of textile wastewater is disclosed. The color elimination from textile wastewater, as well as decrease of salts, total suspended solids, chemical oxygen demand (COD) and total organic carbon (TOC), is carried out passing the textile wastewater through a column filled with the prepared adsorbent.

  • Patent number: 8496984
    Abstract: Mycotoxins prevailing in Northern climates have been until now proven difficult to deactivate in animal feed by binding, in contrast to mycotoxins prevailing in the Southern climates. Meanwhile, both types of toxins present a considerable risk factor for agricultural animal health and performance. A method of adsorbing and rendering harmless for animals an expanded range of both Northern and Southern mycotoxins found in contaminated feed is proposed. According to the invention, a combination of modified plant ligno-polysaccharide material and traditional mycotoxin binding components is added to the feed of agricultural and companion animals in an amount sufficient to abate the negative effects of both types of mycotoxins present.
