A kind of preparation method of instant loquat leaf tea bag fermented by probiotics

Abstract

The invention provides a preparation method of an instant probiotic-fermented loquat leaf tea bag and belongs to the technical field of preparation methods of loquat leaf tea bags. The preparation method comprises steps as follows: raw material pretreatment: fresh loquat leaves in the same growth period are selected, put into a 7.5% sodium bicarbonate aqueous solution, soaked for 1 h and mashed with a tissue masher until the diameters of 80% of the leaves are 5 mm or below; strain activation: three kinds of freeze-dried lactobacillus powder are adopted, an MRS culture medium is prepared and subpackaged in three test tubes with the capacity of 10 mL, and the three kinds of strain powder are injected into the three test tubes respectively; inoculated fermentation: the mashed loquat leaves are taken, the three lactobacillus solutions are mixed in the volume ratio being 1:1:1, each 100 g of the loquat leaves are inoculated with 10 ml of the lactobacillus solutions, put into a constant-temperature and constant-humidity incubator at the temperature of 37 DEG C and the relative humidity of 95% and cultured for 5-8 h, and all the fermented broken loquat leaf pieces are stirred and rubbed repeatedly with hands wiped with 75% alcohol pad until the leaves turn from green to brown; the leaves are dried, crushed and sieved with a 40-mesh sieve and subpackaged into instant tea bags in the specification of 1.0 g / bag.

Description

technical field [0001] The invention relates to a preparation method of loquat leaf tea bag fermented by probiotics, and belongs to the technical field of the preparation method of loquat leaf tea bag. Background technique [0002] Loquat leaves are the leaves of the Rosaceae plant loquat Eriobotryajaponiea (Tllunb.) Lindl. The loquat leaves are included in the previous editions of the Chinese Pharmacopoeia. They have good anti-inflammatory and antitussive effects and are commonly used in clinical treatment of acute and chronic respiratory diseases. Loquat leaves are not only rich in functional compounds such as flavonoids, triterpenoid acids, polysaccharides and volatile oils, but also contain nutrients such as inorganic salts, proteins, vitamins and amino acids. Loquat leaves grow all year round. At present, some leaves are used to separate and extract effective functional components, and most loquat leaves are incinerated as garbage, resulting in waste of resources. [0...

Problems solved by technology

Loquat leaves grow all year round. At present, part of the leaves are used to separate and extract effective functional components, and most of the fallen leaves are burned as garbage, resulting in waste of resources.

[0003] The folks have long been in the habit of drinking loquat leaf tea, but the method is to wash the loquat leaves, dry them, and boil them in boiling water for 30 minutes or longer. Breakdown of Nutrients
