TH80947A - Tea extract - Google Patents

Abstract

DC60, a tea extract containing solids from tea brewed with water, contains magnesium, manganese, calcium, and potassium ions in amounts less than 1.76. The eucidine distance was calculated using Formula 1 (chemical formula), where [Mg] is the magnesium ion concentration in ppm, [Mn] is the manganese ion concentration in ppm, [Ca] is the calcium ion concentration in ppm, and [K] is the potassium ion concentration in ppm. [Ca] is the manganese ion concentration in ppm, [Ca] is the calcium ion concentration in ppm, and [K] is the potassium ion concentration in ppm. Less than 1.76

Claims (6)

1. The process for preparing tea extract involves brewing tea with water. The tea extract contains magnesium, manganese, calcium, and potassium ions in amounts calculated using the eucidine distance formula 1 (chemical formula), where [Mg] is the concentration of magnesium ions in ppm, [Mn] is the concentration of manganese ions in ppm, [Ca] is the concentration of calcium ions in ppm, and [K] is the concentration of potassium ions in ppm. (Less than 1.76) 2. The process for preparing the tea extract as per claim 1, which involves concentrating the extract. 3. A process for preparing the tea extract as per claim 1, consisting of a preservative of 100 to 300 ppm of benzoate and/or sorbate. 4. The process for preparing tea extract consists of the following steps: (a) preparation by brewing tea leaves with water; (b) concentration of the brewed tea; and (c) adjustment of the magnesium, manganese, calcium, and potassium ions in relation to each other in the brewing or concentration process to obtain a tea extract whose eucidine distance is calculated using formula 1 (chemical formula), where [Mg] is the concentration of magnesium ions in ppm of tea extract, [Mn] is the concentration of manganese ions in ppm of tea extract, [Ca] is the concentration of calcium ions in ppm of tea extract, and [K] is the concentration of potassium ions in ppm of tea extract, less than 1.76. 5. The process stipulated in claim number 4, which adjusts the amounts of magnesium and manganese. 6. The process for preparing concentrated tea extracts consists of the following steps: (a) brewing the tea leaves in water to obtain a tea infusion containing tea solids; (b) separating the plant substances, for example, by filtration and/or centrifugation; (c) alternatively, concentrating the brewed tea; (d) alternatively, treating the brewed tea with one or more enzymes; (e) removing the cream from the brewed tea; (f) concentrating the cream-removed brewed tea; (g) adjusting the relative amounts of magnesium, manganese, calcium, and potassium ions in the brewed tea using electrodialysis, so that the eucidine distance calculated using the formula above is less than 1.76; (h) adding alternative carbohydrates; (i) concentrating the electrodialysis-treated tea extract to obtain a concentrated liquid tea extract; (j) adding alternative components traditionally used in tea products, for example, preservatives, pH adjusters, colorants, and/or flavorings; and (k) removing water from the alternative concentrated liquid tea extract. Provides a concentrated tea extract in powder form.
