The present invention provides a method of a composition containing plant extracts for enhancing the gene expression level of TGM1, KRT, AQP3, FLG, GBA, and HAS. Compared to a single plant extract, the combination of the plant extracts of the present invention can more effectively enhance the expression level of skin moisturizing genes. The plant extracts constituting the composition include: an extract of spinach, blueberry, Pu-erh tea, or Four Seasons Spring tea.

The invention relates to citrus fibers in dry form having a storage modulus (G) of at least 50 Pa, said G being measured on an aqueous medium containing an amount of 2 wt % citrus fibers dispersed therein under a low-shear stirring of less than 10000 rpm.

The invention relates to a tea-based beverage precursor comprising tea solids and at least 0.01% w/w water-dispersible biopolymer, wherein the water-dispersible biopolymer has a Trouton ratio of at least 300, preferably 400, more preferably 450 measured as a 0.2% w/w aqueous solution at 20 degrees Celsius, wherein the weight ratio of tea solids to water-dispersible biopolymer is at least 2:1, preferably at least 3:1. The invention also relates to a tea-based beverage comprising water and the tea-based beverage precursor of the first aspect of the invention, wherein the tea-based beverage comprises 0.0001 to 0.1% w/w of the water-dispersible biopolymer.

A ready-to-drink tea beverage contains tea extract, aerated water and benzoate, such as a benzoic acid salt. The beverage and/or the aerated water can contain at least 5.0 ppm dioxygen (O2) and preferably at least about 5.0 ppm O2. The aerated water can reduce or prevent benzene formation and can reduce the benzene content of the beverage. The beverage can lack dimethyl dicarbonate and/or ascorbic acid. The water can be aerated before and/or after the beverage is dispensed in a can or another suitable container.

The present disclosure provides a method for regulating expression of PDGFC, FGF2, IGF1R, PTGIS, NOS3, EDN1, PLAT, PROC, VWF, F3, SERPINE1, IL-8, ICAM1, VCAM1, and CASP8 genes, including administering to a subject in need thereof a composition including an effective amount of a plant extract, wherein the plant extract includes at least one combination selected from the group consisting of a grape seed extract and a Four seasons spring tea extract, a black tea extract and a spinach extract, the grape seed extract and the spinach extract, the grape seed extract and a green coffee bean extract, a red wine extract and a Pu-erh tea extract, and the grape seed extract and the Pu-erh tea extract.

The present invention provides a composition containing plant extracts and the use thereof. Compared to a single plant extract, the combination of the plant extracts of the present invention can effectively enhance the synthesis of collagen. The plant extracts constituting the composition include: an extract of grape seed, black tea, green tea, red wine, citrus, spinach, green coffee bean, blueberry, Pu-erh tea, or Four Seasons Spring tea.

The present invention discloses an apparatus and a method for extracting a component in a solid by using nano-bubbles, the apparatus including a reaction container configured to hold a solid to be extracted, a nano-bubble generating device configured to generate a liquid containing nano-bubbles, and an energy generator, wherein the liquid containing nano-bubbles is used to be mixed with the solid to be extracted, and the energy generator is used to emit energy to the reaction container to burst the nano-bubbles and enhance the extraction effect of the solid in the liquid.

Beverages having an improvement in continuity of aftertaste caused by Rebaudioside D (RebD) and Rebaudioside M (RebM) and methods of production thereof. A content (A) of catechin compound(s) in beverages is adjusted to within a certain range, a total content (B) of RebM and/or RebD in beverages is adjusted to within a certain range, and B/A is adjusted to within a certain range.

Methods for modulating the bitterness and astringency of green tea, and nutritional products having a green tea with reduced bitterness and astringency, are provided. In a general embodiment, the methods comprise performing microfiltration on green tea extract to form a microfiltration retentate and a microfiltration permeate; performing at least one of ultrafiltration or reduced temperature fractionation on the microfiltration permeate; and using the ultrafiltration permeate from the ultrafiltration or the supernatant from the reduced temperature fractionation to make a green tea product. The ultrafiltration permeate or the supernatant can be further concentrated, spray or freeze dried to form a powder, used as a concentrate, or diluted to form a ready-to-drink beverage. In an embodiment, the ultrafiltration is performed on the microfiltration permeate to form an ultrafiltration retentate and an ultrafiltration permeate and then the reduced temperature fractionation is performed on the ultrafiltration permeate to form a supernatant and a sediment.

An object of the present invention is to provide a tea beverage which comprises a chitosan but is prevented from getting cloudy.

According to this invention, there is provided a non-fermented or semi-fermented tea beverage comprising a chitosan having a molecular weight of not more than 7 kDa at a concentration of not more than 200 ppm.
