Freeze-dried Instant White Tea/Sweet Orange Drink Cubes

Objective An instant beverage product of white tea and sweet orange was developed to provide a new venue to promote the abundant healthful ingredients for the market.

Method White tea powder was mixed with sweet orange marmalade, a flavoring agent, sugar, binders, water, and others in one-way and orthogonal tests to optimize the formulation based on the taste panel evaluation. The mixture was formed into cubes, freeze-dried, and packed ready to be dissolved in water for drink.

Result The optimized formulation called for 0.1 g of white tea powder, 5 g of sweet orange marmalade, 0.5 g of a flavoring agent, 5 g of rock candy, 5 g of granular sugar, 5 g of dextrin, 0.5 g of pectin, and 72 g of water.

Conclusion The sweet-tasting beverage with a hint of tartness of the freeze-dried instant white tea/sweet orange drink cubes carried a unique and pleasant harmonious blend of tea and fruit flavors.
