The present application describes a composition for blood glucose control containing green tea extracts (GTE) with gallated catechins (GC) and macromolecule to prevent the intestinal absorption of GC.

A composition is provided to treat and / or prevent for treating skin conditions including fine lines and wrinkles, acne rosacea, surface irregularities of the skin and hyper-pigmentation melasma of the skin, which includes use of a topically applied composition such as an ointment, lotion, cream, serum, gel or pad applied formulation, containing an effective amount of polyphenols, such as green tea based polyphenols, including but not limited to catechins, such as epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicathechin 3-gallate (ECG) and epicatechin (EC). The formulation is preferably composed of 90 percent polyphenol isolates, derived from green tea with potent antioxidant properties, to assist in minimizing free-radical induced skin damage.

To provide a packaged high-catechin beverage in which a low-caffeine green tea extract is added. A packaged beverage containing from 0.03 to 1.0 wt % of non-polymer catechins, in which a low-caffeine green tea extract obtained by a method of brining a green tea extract into contact with a 91 / 9 to 97 / 3 by weight mixture of an organic solvent and water, activated carbon, and acid clay or activated clay is added.

Provided are packaged, tea-based beverages, which stably contain catechins at high concentration, are free of any salty taste, and have the inherent flavor and taste of tea. They contain the following ingredients (A) and (B):(A) from 320 mg / 500 mL to 1,300 mg / 500 mL of non-polymer catechins, and(B) water, wherein:(C) the content of non-epicatechins in the non-polymer catechins is from 40 to 80 wt. %,(D) the content of gallates in the non-polymer catechins is from 35 to 100 wt. %,(E) the weight ratio of the non-polymer catechins to sodium ions is from 12 to 16, and(F) the pH is from 5 to 7.

A consumable composition with antioxidants is described. The consumable composition comprises theaflavin, thearubigin and catechin and has good taste and appearance characteristics. The consumable composition can be black tea having green tea catechins as additives.

A synergistic flame retardant composition comprising a phenolic compound comprising condensed tannin, hydrolysable tannin, lignin, cardanol, quercetin, catechin, epicatechin, anthocyanidin, catechol, dopamine, hydroxytyrosol, adrenaline, 4-hydroxyphenylacetic acid, gallic acid, digallic acid, methyl gallate, ellagic acid, phloroglucinol, hexahydroxydiphenic acid, luteic acid, casuarictin, or a combination thereof; and a phosphorus-containing compound comprising a C5-7 carbocyclic polyol substituted with at least one phosphate group.

The disclosed item is a composition comprising catechins and sialic acid to provide an effective prevention and treatment for Helicobacter Pylori infection. This composition inhibits growth of Helicobacter pylori, and can increase the antioxidant activity of gastric mucosal cells through reducing the production of O2.−, H2O2 and NO, and decreasing the expression of inducible nitric oxide synthase (iNOS) in cells. The apoptotic damage of stomach caused by Helicobacter pylori was decreased through up-regulation of autophagy to enhance the defensive ability of gastric epithelial cells toward Helicobacter pylori. Therefore the composition can be used in the treatment or prevention on damages caused by Helicobacter pylori infection.

The invention belongs to the historical relic protection and repair technical field, in particular relates to an antibacterial solidifying agent of excavated bamboo and wood ware. The invention is characterized in that the solidifying agent comprises the following components in parts by weight: 4-100 parts of oligomeric chitosan, 20-200 parts of catechin, 600-1300 parts of polyethylene glycol, 850 parts of water and 150 parts of ethanol. The invention researches the fundamental substances of bamboo and wood and the structure and properties of inclusions, selects oligomeric chitosan of which structure is similar to the basic structural unit of cellulose and the polyphenol substance catechin existing in plants and provides a solidifying agent with natural antibacterial substances for excavated bamboo and wood ware. The solidifying agent maintains the solidifying effect of PEG, has bacteriostasis and antibacterial effect, is environmentally friendly and belongs to the green and environmentally friendly antibacterial solidifying agent.

The invention provides a processing method of high catechin beverage with low biter taste and belongs to the processing field of food. The processing method comprises the following steps of: 1) taking green broken tea, extracting three times continuously with water so as to obtain an extract liquid I, an extract liquid II and an extract liquid III; 2) coarsely filtering the extract liquid I, the extract liquid II and the liquid III so as to remove tea leaves; 3) respectively processing the extract liquid II and the extract liquid III by use of tannase so as to obtain the corresponding enzymolysis liquid I and enzymolysis liquid II; 4) mixing the extract liquid I, the enzymolysis liquid I and the enzymolysis liquid II to obtain a tea mixed liquid; 5) performing film separation process on the tea mixed liquid so as to obtain clarified tea water; 6) adding VcNa and cyclodextrin into the clarified tea water for mixing so as to obtain the tea beverage; and 7) filtering, sterilizing and bulking the tea beverage to obtain finished products. The tea beverage obtained by the processing method is a green-yellow tea beverage, wherein the content of catechin is more than or equal to 800mg / l; and the tea beverage belongs to a functional tea beverage with pure taste and crisp mouth feel and without obvious bitter taste.
