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.

This system for concentrating solvent-containing articles involves a first step in which: a supply flow (a) comprising solvent-containing articles containing a solute and a solvent (b) is caused to flow counter to or parallel with a permeant flow (d) through a forward osmosis membrane (o); the solvent (b) contained in the supply flow (a) is made to pass through the forward osmosis membrane (o) and to move into the permeant flow (d); and a concentrate flow (c) formed from the concentrated solvent-containing articles and a flow (e) formed from the diluted permeant flow (d) are obtained, wherein the permeant flow (d) is an inorganic salt solution containing multivalent cations, and the temperature of the permeant flow (d) in the aforementioned first step is 5-60 C.

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.
