Example Embodiment

[0012] Example 1

[0013] (1) Take 0.3 grams of lotus leaf tea partner (containing 0.3 grams of malic acid), 1 gram of commercially available lotus leaf tea, and a thermos cup, add lotus leaf tea into the thermos cup, then add lotus leaf tea partner, and then add 100 ml Boil water, stir evenly, and keep warm for 20 minutes to obtain lotus leaf tea brewing liquid.

[0014] After brewing, the lotus leaf tea residue was filtered out, and the residue was brewed for the second time, and the filtrate was sampled for detection by high performance liquid chromatography. The result was that the dissolution rate of nuciferine was 76.53% in the first brewing.

[0015] (2) Add the lotus leaf tea filter residue into the thermos cup, then add 0.3 g of lotus leaf tea partner, then add 100 ml of boiling water, stir well, and keep warm for 20 minutes. After brewing, it was filtered, and the filtrate was sampled for detection by high performance liquid chromatography. As a result, the dissolut...

[0017] Example 2

[0018] (1) Take 0.1 grams of lotus leaf tea partner (containing 0.1 grams of malic acid), 1 gram of commercially available lotus leaf tea, and a thermos cup, add lotus leaf tea into the thermos cup, then add lotus leaf tea partner, and then add 100 ml Boil water, stir evenly, and keep warm for 20 minutes to obtain lotus leaf tea brewing liquid.

[0019] After brewing, the lotus leaf tea residue was filtered out, and the residue was brewed for the second time, and the filtrate was sampled for detection by high performance liquid chromatography. As a result, the dissolution rate of nuciferine was 73.65% in the first brewing.

[0020] (2) Add the lotus leaf tea filter residue into the thermos cup, then add 0.1 g of lotus leaf tea partner, then add 100 ml of boiling water, stir well, and keep warm for 20 minutes. After brewing, it was filtered, and the filtrate was sampled for detection by high-performance liquid chromatography. As a result, the dissolution rat...

[0022] Example 3

[0023] (1) Take 1.0 grams of lotus leaf tea partner (including 1.0 grams of malic acid), 1 gram of commercially available lotus leaf tea, and a thermos cup, add lotus leaf tea into the thermos cup, then add lotus leaf tea partner, and then add 100 ml Boil water, stir evenly, and keep warm for 20 minutes to obtain lotus leaf tea brewing liquid.

[0024] After brewing, the lotus leaf tea residue was filtered out, and the residue was brewed for the second time, and the filtrate was sampled for detection by high performance liquid chromatography. As a result, the dissolution rate of nuciferine was 76.88% in the first brewing.

[0025] (2) Add the filter residue of lotus leaf tea into the thermos cup, then add 1.0 g of lotus leaf tea partner, then add 100 ml of boiling water, stir well, and keep warm for 20 minutes. After brewing, it was filtered, and the filtrate was sampled for detection by high-performance liquid chromatography. As a result, the dissolution r...

Abstract

The invention discloses a lotus leaf tea mate and a lotus leaf tea brewing liquid. The lotus leaf tea mate comprises malic acid, and the lotus leaf tea mate and lotus leaf tea are matched according tothe following ratio that the content of the malic acid in the lotus leaf tea mate prepared from 1 g of the lotus leaf tea is 0.1-2 g. The solubility of nuciferine in water can be increased under acidic conditions. When the lotus leaf tea mate is added in the process of brewing the lotus leaf tea, the acidity of the brewing liquid can be increased, the dissolution of lotus leaf alkaloids, especially the nuciferine is promoted, and the problem is solved that the main active ingredient, namely the nuciferine, of the lotus leaf tea is unlikely to be dissolved out according to traditional brewingmethods. The lotus leaf tea brewing liquid can be obtained by brewing the lotus leaf tea mate and the lotus leaf tea in boiling water, and the addition amount of the malic acid is 0.1-2 g in each 100ml of the lotus leaf brewing liquid; the dissolution rate of the nuciferine during first brewing is higher than 70%, and the dissolution rate of the nuciferine after third brewing can reach 90% or above, so that the efficacy of the lotus leaf tea is greatly improved.

Description

technical field [0001] The invention relates to a lotus leaf tea mate and lotus leaf tea brewing liquid, belonging to the field of food. Background technique [0002] Due to the improvement of living standards, the incidence of obesity has risen sharply. According to relevant data: my country's adult overweight ratio is about 20-30%, and it has reached 35-40% in big cities. In order to help lose weight, a large number of lotus leaf products have appeared on the market in recent years, especially lotus leaf tea. The lotus leaf is the dried leaf of the Nymphaeaceae plant lotus. The lotus leaf tastes bitter and flat, and returns to the liver, spleen, and stomach meridians. Studies have shown that the alkaloids and flavonoids in lotus leaf have activities such as lowering blood fat, inhibiting cholesterol, and anti-oxidation, among which nuciferine has a certain weight-loss effect. Nuciferine has the effect of losing weight because it can effectively decompose fat in the body...
