Processing technology of tea bakery foods - a Review

Tea foods, especially tea bakery foods, play an important role in bridging the gap between supply and demand of tea industry. This paper reviews the processing technology of tea bakery foods which include tea breads, tea cakes, and tea biscuits during the past thirty years. It also points to the fact that there are no uniform quality evaluation methods for tea bakery foods. Effect of the chemical composition of tea on the quality of bakery food is discussed. According to differences in texture, chemical composition, and biological activity of functional components, different ingredients and their ratios should be adjusted to obtain high-quality tea bakery foods. To effectively preserve the special tea flavour, biological activities of tea components should be retained as much as possible. Tea baked foods were mainly evaluated through senses. There were many differences in the sensory evaluation indices, evaluation criteria, and the scores by different experts. Further, this paper provides a critical outlook of the developments needed in processing technology and quality improvement of tea bakery foods.
