186 results about "Mastication" patented technology

Chewing or mastication is the process by which food is crushed and ground by teeth. It is the first step of digestion, and it increases the surface area of foods to allow a more efficient break down by enzymes. During the mastication process, the food is positioned by the cheek and tongue between the teeth for grinding. The muscles of mastication move the jaws to bring the teeth into intermittent contact, repeatedly occluding and opening. As chewing continues, the food is made softer and warmer, and the enzymes in saliva begin to break down carbohydrates in the food. After chewing, the food (now called a bolus) is swallowed. It enters the esophagus and via peristalsis continues on to the stomach, where the next step of digestion occurs.

Chewing gum compositions

The present invention relates to chewing gum composition comprising a polymeric surface active agent. A second aspect of this invention relates to a crunchy chewing gum wherein the crunchy texture is provided by particulate polyphosphate particles within the formulation and which lasts through the initial minutes of mastication. The chewing gum composition may also contain a cationic material and or an orally active metallic ion. The chewing gum composition will provide surface conditioning effects on a subject's teeth and or oral mucosa and the crunchy texture is used as a sensate to reinforce these effects. The surface conditioning effects can be measured through in vitro or in vivo testing. The in vitro testing shows a total surface energy and or a lewis base score to increase immediately after treatment with the chewing gum and then decrease over time. The in vivo testing shows a water contact angle of the oral mucosa to decrease after treatment with the chewing gum composition and/or a significantly higher smooth teeth feel relative to other chewing gum compositions. The present invention also relates to methods of providing surface conditioning effects to a subject comprising administering to the subject a chewing gum comprising a polymeric surface active agent. The present invention also relates to methods of reducing astringency of a chewing gum containing an orally active metallic ion without significantly reducing the efficacy of the metallic ion.

Sheath material for optical fiber cable, and production process thereof

The present invention relates to a sheath material for an optical fiber cable, and a production process thereof. The sheath material comprises, by weight, 85-95% of a polyolefin base material, 2.35-2.85% of carbon black, 0.5-1% of an antioxidant, and 0.8-1% of an additive, wherein the polyolefin base material comprises a polyethylene base material and a modifier, and the additive comprises a fluorine-containing rheological agent PPA, a lubricant, a plastic brightening agent and a softener. During production, carbon black is made into a masterbatch; PPA is made into a masterbatch by using a polyethylene base material; the carbon black masterbatch, the PPA masterbatch, an antioxidant, a plastic brightening agent and a softener are mixed; the mixed material is added to EVA to mix; the resulting mixture is added to polyethylene to mix, and then mastication extrusion is performed through a plastic extruder. According to the present invention, high and medium density polyethylene is adopted as a base material for the optical fiber cable sheath, such that a chemical performance is stable; and various auxiliary materials are added to the polyethylene base material, such that performances of the optical fiber cable sheath are improved, and various use requirements of the optical fiber cables are met.

Production method of anti-bacterial SBR (styrene butadiene rubber) foaming material

The invention relates to a production method of an anti-bacterial SBR (styrene butadiene rubber) foaming material. The ingredients includes, by weight parts, 20 to 40 parts of natural rubber, 60 to 80 parts of main SBR materials, 10 to 15 parts of process/operation auxiliaries, 20 to 30 parts of vulcanization /foaming auxiliaries, 40 to 50 parts of processing oil and 120 to 150 parts of reinforcing filler. The production method includes steps of firstly, masticating; secondly, mixing; thirdly, opening smelting; fourthly, fine smelting; fifthly, open smelting secondarily; sixthly, extruding; seventhly, vulcanizing and eighthly, foaming. The production method is characterized in that 3 to 5 parts of nanometer silver powder are added into the ingredients according to mass ratio, the first step of the production method includes feeding the natural rubber and the nanometer silver powder into an open smelting machine or a fine smelting machine to realize mastication, and the second step of the production method includes feeding a primary product of the first step, the main SBR and the process/operation auxiliaries into the fine smelting machine to mix. The production method of the anti-bacterial SBR foaming material has the advantages that anti-bacterial nanometer silver powder can prevent physiological breeding of bacteria while original characteristics of the foaming material are kept.
