Embodiment 1

[0017] Example 1: Preparation of organic selenium biological agent

[0018] Take 30g selenium dioxide, 30g sodium bicarbonate, 10g methionine, 35g brown sugar, 3g urea, 3g potassium dihydrogen phosphate, 2g magnesium sulfate, 2g manganese sulfate, 4g calcium chloride, 30mL EM active bacteria. First add selenium dioxide into 5000g water and stir to dissolve, then add methionine, mix and dissolve, then add sodium bicarbonate, adjust the pH to 6.5-7.5, then add brown sugar, urea, potassium dihydrogen phosphate, magnesium sulfate, manganese sulfate, Calcium chloride, 6500 grams of water and EM active bacteria are dissolved and then anaerobic fermentation is carried out, the fermentation temperature is controlled at 20-25°C, and the time is controlled within 7 days, and the organic selenium biological agent can be made.

Embodiment 2

[0019] Example 2: Production of selenium-enriched tea leaves.

[0020] The organic selenium biological agent prepared in Example 1 was diluted with water to 65 times its original volume. At this time, the selenium content was 28.5 ppm. Use a spraying device to spray the diluted organic selenium biological agent on the surface of the growing tea leaves to make it less dripping. The dosage is controlled at 20kg liquid medicine / mu of tea plantation. The distance between the front and rear of each tea tree in each mu of tea field is not less than 50-60 cm. The application time is 30 days before picking, and the average is sprayed once every 6 days, a total of 5 times. During use, the outdoor temperature should be 10-15 ℃, and it should not be used in rainy days. If it rains suddenly after the spraying, the spraying amount is the same as the previous time because it is applied once after the rain stops. After picking, the finished tea is made by the conventional tea production ...

Abstract

The invention relates to a method for producing casein phosphopeptide by using milk, which is performed according to the following process steps: 1) defatting and removing impurities: using a butterfly type centrifuge to remove fat and the impurities through secondary centrifugal separation at the temperature of 30-40 DEG C; 2) adding an enzyme for hydrolysis: adding 0.5% trypsinase into the defatted milk, using a 0.3-0.7mol / l sodium hydroxide solution to regulate pH to 7.5-8.5 while adding, hydrolyzing for 1.5-2.5 hours, raising the temperature to 70-90 DEG C and inactivating the enzyme within 30 minutes; 3) debitterizing and purifying: using a stirring machine at the rotational speed of 30-50r / min to stir an enzymatic hydrolysis solution; adding active carbon powder which accounts for 0.05-0.1% of the weight of inventory rating; regulating the pH value to 4.2-5.0; and using a diatomaceous earth filtering machine to filter; and 4) homogenizing and spray-drying: sterilizing the liquid casein phosphopeptide at the temperature of 80-100 DEG C for 15-30 seconds, and then passing through a homogenizer at the homogenizing pressure of 15-25MPa; and further passing through a spray-drying tower for getting the powdery casein phosphopeptide. The content of the phosphopeptide achieves 20%, the purity is high, and the casein phosphopeptide only has light bitterness and is good in color and luster.

Description

technical field [0001] The present invention relates to a production method of tea leaves. Specifically, it relates to a production method of selenium-enriched tea. Background technique [0002] Selenium is one of the essential trace elements for human beings. At present, scientific institutions and health organizations all over the world have unanimously recognized that there are eight undisputed essential trace elements for human body: selenium, iron, manganese, copper, cobalt, zinc, molybdenum, and iodine. [0003] There are more than 40 human diseases known to be related to selenium deficiency, including cancer, cerebrovascular disease, diabetes, liver disease, and thyroid hormone imbalance. [0004] In 1973, the World Health Organization confirmed that the essential elements of human body are: iron, selenium, copper, zinc, iodine and so on. In order to maintain the normal operation of life, the human body must get enough selenium from food. According to statistics, ...
