The vigorous development of the novel-tea beverage industry has stimulated and guided the adjustment and upgrading of the tea industry structure. The scale of production and sales of raw materials for novel-tea beverages has been increasing year by year, yet related research on these raw materials remains scarce. Blending is a crucial method for innovation in tea quality. This paper systematically reviews the research on blending raw materials from the perspective of tea blending. It analyzes the challenges faced by tea blending techniques in the current novel-tea beverage market and, in a forward-looking manner, identifies key areas for future research. This provides some inspiration and reference for in-depth studies on teas used as raw materials.
