Soluble tea
Various drinks are referred to as soluble tea or instant tea .
Powdered tea extract is obtained by extracting, concentrating and spray drying an aqueous tea solution . The extract is around 40 percent of the amount of tea used.
In addition, beverages in granulate form are called instant tea; The most common in trade is lemon tea. It is a semi-finished product that is infused with hot or cold water. In addition to powdered tea extract (the proportion is around 10 grams per liter of finished drink), these products also contain sugar , dextrose , or sweeteners , as well as flavorings and stabilizers. "Since poorly soluble precipitates form in tea extracts made from tea flavins , tea leaves and caffeine when they cool, up to 100 g of potassium or sodium hydroxide are added to every 1 kg of cold water-soluble tea extract ."
Children's tea rulings by the BGH
In many cases, instant teas were and are marketed as a product for the nutrition of children (“children's tea”). Due to the high sugar content, however, instant tea is harmful to dental health. In the 1970s and 1980s, many children suffered permanent damage to their teeth due to "constant sucking" on teat bottles filled with instant tea. This was first scientifically described in 1981 as a new type of deciduous tooth caries. In some cases, prostheses had to be used due to the complete loss of the milk teeth. From 1985 the Federal Health Office issued an express warning of the dangers of teas containing sugar. As a result, there were lawsuits for damages against the manufacturers of the children's teas, who often also sold feeding bottles and teats at the same time. The so-called Kindertee-I case, on which the Federal Court of Justice ruled in 1991, became known. According to this, the manufacturer of the children's tea was liable for the damage to health that occurred because he had not adequately warned consumers about the dangers of "constant sucking". The decision represents a fundamental decision of product liability law . In several further decisions on this topic (Kindertee II-IV), the BGH specified further requirements for producer and organ liability.
