Abstract

The patent is a new development of an Instant Liquid Tea Concentrate, according to the norms and standards of food science and related industries. Since the discovery of tea as a healthy drink some 4000 years ago, conventionally, the tea leaves have been dissolved in hot or cold water before consumption. The derivatives of tea would dissolve in hot or cold water with flavor and aromas creating a tasty, healthy drink. A tea bag, for instance, uses the same traditional method, though with reduced preparatory hazard.In addition, tea extracts in powder forms are manufactured with chemical extraction methods. In a number of processes, the tea extract in powder form is followed by the preparation of aqueous tea concentrates as a secondary product.Accordingly, the powdered tea extracts is dispersed in water while adding preservatives in order to manufacture aqueous tea concentrates. This aqueous tea concentrates differ from the “INSTANT LIQUID TEA CONCENTRATE”. In fact, aqueous tea concentrates are secondary products but, they are not direct end products of the particular extraction method but the INSTANT LIQUID TEA CONCENTRATE is a direct result of the respective process.The new development makes it possible for the derivatives that create both the flavour and the aroma (and even other dormant aroma) to be extracted to a liquid base, the final product being—Liquid Tea Concentrate in instant form. Accordingly, the base used for the Instant Liquid Tea Concentrate manufacture is glycerol (or its equivalent forms of 1,2,3 Propanetriol or Glycyl alcohol or Glycerin—in lieu of Glycerol). The final product—Instant Liquid Tea Concentrate can be added to hot or cold water instead of tea leaves or aqueous tea concentrates at the final point of consumption.Tea refers to the botanical name “Camellia sinensis” which comprises of four main types—black tea, green tea, white tea or oolong tea can be used for the development, making it possible for the consumers to prepare an instant tea using the Instant Liquid Tea Concentrate. The most commonly found tea on the market are black tea, oolong tea, green tea and white tea, all of which can be made from the same tea bushes.
