The invention relates to a manufacturing process for dual-
calcium-fortified low-
fluorine brick tea. The manufacturing process comprises the following steps: picking Sichuan local summer tea with one
bud and four to five leaves,
drying and crushing the tea, stacking to ferment the tea naturally, and changing the taste of the tea to obtain
raw material tea; mixing and stirring the
raw material tea and
calcium uniformly to prepare
calcium-containing mother tea; mixing and stirring the calcium-containing mother tea and the fermented
raw material tea uniformly to complete the addition of the calcium; pressing,
cutting and shaping by using a mold after the raw materials of the tea added with calcium are sterilized and humidified by high-temperature steam;
drying the pressed,
cut and shaped tea raw materials in a
drying machine at 80 DEG C, wherein the calcium is obtained by mixing 1 part of calcium citrate and 3 to 5 parts of
calcium carbonate. According to the manufacturing process, the
active ingredient, namely tea
polyphenol, in the
brick tea and the conventional
flavor are not changed, the
brick tea manufactured by the manufacturing process provided by the invention is made in a heat-insulated cup and is convenient and applicable. By the manufacturing method, the
calcium content in the brick tea is improved by 1,000 to 5,000 mg / Kg, and 30 to 100 mg of the calcium can be supplemented per day if 20 g of brick tea is used per day, so that the calcium
nutrition is improved greatly. The
fluorine content of the brick tea is 150 to 180 mg / Kg and is much lower than a
national standard; the
fluorine poisoning cannot be caused after the brick tea is drunk for a long time.
