Preparation method of matcha with low pollution and matcha

Abstract

The invention belongs to the technical field of deep processing of tea leaves, and particularly relates to a preparation method of matcha with low pollution and the matcha. Aiming at the problem that in the prior art, the content of perchlorate in matcha is generally high, the invention provides the preparation method of the matcha with low pollution and the matcha, and the preparation method comprises the following steps: selecting a planting site of tea trees, selecting soil with a perchlorate concentration less than 1.20 ng / g as planting soil, and planting the tea trees; planting and cultivating, covering the tea tree with a sunshade net for 10-20 days in a time period from the germination of tea buds of the tea tree to the picking of tea leaves; picking and transporting, picking fresh leaves by using a picking machine, loading the fresh leaves into a cubic bag container, and transporting the tea leaves into a green leaf groove; and processing, including but not limited to the steps of fixation, cooling, drying, stem and leaf separation, grinding and sieving, so as to obtain the finished matcha. According to the invention, the planting soil of the tea trees is strictly selected, and the content of perchlorate in the finished matcha is reduced from the source.

Description

technical field

[0001] The invention belongs to the technical field of tea deep processing, and in particular relates to a preparation method of low-pollutant matcha and the low-pollutant matcha. Background technique

[0002] Matcha originated in the Sui and Tang Dynasties of China. It has a history of thousands of years. In ancient times, the young leaves of tea leaves in spring were steamed and then made into tea cakes for preservation. Before eating, they were baked and dried again on the fire. The natural stone is ground into powder and brewed directly for drinking. Since the Ming Dynasty, tea has been used instead, brewed for soup, and tea dregs are discarded. Nowadays, as international food manufacturers launch matcha-flavored foods, such as matcha ice cream and matcha milk, consumers are increasingly interested in matcha.

[0003] With the widespread promotion of the application of matcha, consumers are paying more and more attention to the health of the product. I...

Embodiment 1

[0039] The present embodiment provides a kind of preparation method of low-pollutant matcha, comprising the following steps:

[0040] Step 1: tea tree planting site selection, select the soil with a perchlorate concentration of 1.00ng / g in the soil as the planting soil, and plant tea trees;

[0041] Step 2: Planting and cultivation. During the period from the budding of the tea tree to the tea picking, only organic fertilizers are used, and green prevention and control technology is used to manage diseases and insect pests. Among them, the green prevention and control technology is a digital yellow board, covered with a sunshade net For 20 days, the covering method of the sunshade net is the suspension covering method, the distance between the sunshade net and the tea tree is 80cm, and the sunshade net is made of polyethylene material with a plasticizer content of 0.1%.

[0042] Step 3: Picking and transporting, using picking machines, picking fresh leaves, putting them into a...

Embodiment 2

[0057] The present embodiment provides a kind of preparation method of low-pollutant matcha, comprising the following steps:

[0058] Step 1: tea tree planting site selection, select the soil whose perchlorate concentration is below 1.10ng / g in the soil as the planting soil, and plant tea trees;

[0059] Step 2: Planting and cultivation. During the period from the tea buds of tea trees to the time before tea picking, only organic fertilizers are used, and green prevention and control technologies are used for pest management. Among them, the green prevention and control technologies are tea geometrid traps and long beetle Basin traps are covered with sunshade nets for 10 days. The sunshade nets are covered by the suspended covering method. The distance between the sunshade nets and the tea trees is 60cm. The sunshade nets are made of polyethylene material with a plasticizer content of 0.08%.
