example 1

[0048] Experiments were carried out to determine the effect of different tea ingredients and processing conditions on reducing benzene content. Each tea sample was prepared in a 20 milliliter (mL) vial and contained 0.03 g / mL LEDTA. The parameters tested were sodium benzoate concentration, presence or absence of sucralose, concentration of high fructose corn syrup (HFCS), pH established by varying phosphoric acid content, water aeration (deaerated or not) and reverse osmosis water treatment. Type (helium purged or membrane). see figure 1 .

[0049] The tea was black raspberry flavored tea and all other components of the tea samples other than the parameters tested were the same for each sample. Specifically, the tea contains sweeteners (such as sugar and / or substitutes), black tea powder, acid, preservatives, raspberry flavor and water.

[0050] The presence or absence of sucralose was a parameter tested because the artificial sweetener is thought to slow down the formatio...

Abstract

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.

Description

Background technique [0001] The present invention generally relates to ready-to-drink tea beverages. More specifically, the present invention relates to ready-to-drink tea beverages with reduced benzene formation and methods for their preparation. [0002] Benzene is a volatile organic compound (VOC) known to be carcinogenic to humans and may be present in food and beverages. Eating foods high in benzene can lead to symptoms such as vomiting, upset stomach, dizziness, drowsiness, convulsions, fast or irregular heartbeat, and death. Long-term exposure to benzene can affect the blood by damaging the bone marrow and reducing red blood cells, which can lead to anemia. The immune system may also be affected, increasing the chance of infection, and leukemia may also develop. [0003] Benzene occurs in food for several reasons, such as the use of contaminated carbon dioxide in carbonated beverages, leaching from packaging materials, contamination of the environment and water sourc...
