Preparation process of black tea from yerba mate and the respective resulting product

Abstract

The present invention abstract describes the steps of a process for the preparation of black tea and the respective end product, wherein, in the initial step of the proposed process for producing black tea, the young yerba mate leaves (buds) are subjected to withering for a certain time. Next, the already withered leaves are rolled; next, the fermentation is carried out, and after such fermentation, drying and segregation are performed.

Claims

1. A preparation process of black tea from yerba mate, consisting of the following steps: withering young leaves (buds) of yerba mate, wherein the young leaves are buds, by dehydrating for 12 to 14 hours in order to remove 65 to 67% moisture, wherein the dehydrating is performed by placing the young leaves on a rectangular wooden sieve with bottom screen, wherein the sieve and bottom screen are supported by a tripod one meter above the floor and wherein the sieve and bottom screen from the floor to the height of the tripod are enclosed with wood, forming a tunnel by installing a hot air fan at one end, extracting juice from the young leaves and immediately rolling the young leaves for the first time for 20 minutes, thereafter performing an oxidation or a fermentation process in which the young leaves are placed in taquara sieves near a fan for about one hour, thereafter performing an oven drying step at 110° C. for about 24 minutes, and, thereafter sorting and separating larger/whole young leaves, broken young leaves and particulate young leaves each of which can be used for making black tea.

Description

DETAILED DESCRIPTION OF THE INVENTION

(1) The embodiment of the invention proposed in this specification is achieved by describing the different steps required for carrying out the present application, such that it can be fully reproduced by means of appropriate technique, thus allowing full characterization of the claimed process functionality.

(2) Based on the different steps described that express the best or preferential way to carry out the process now devised, the descriptive part of the report is based, thus clarifying aspects that may have been presumed, so as to clearly determine the protection now claimed.

(3) These operations may vary, provided that they do not depart from the initially claimed subject matter.

(4) In this case, the products can be generated by different operations.

(5) In the preparation process developed, the young leaves of yerba mate should go through the following steps: withering the young leaves (buds) of yerba mate (withering step). The leaves should dehydrate for 12 to 14 hours until they wither, which is the time required to remove 65 to 67% of moisture. One of the ways to do this is as follows: the buds are placed on rectangular wooden sieves having a mesh on the bottom, supported by tripods placed at one meter from the floor. The whole frame surrounding the sieves from the floor to the tripod height will be closed with wood (forming a tunnel) and a hot air fan will be installed at one end. In this step, it is crucial to wither the leaves, and said method may be cited or changed; next, it is necessary to extract the juice from the leaves and immediately start rolling the leaves for the first time for 20 minutes (first rolling). In this step, it is crucial to roll the leaves, and said method may be cited or changed; next, the oxidation or fermentation process is performed (oxidation or fermentation step), in which the leaves are placed in bamboo sieves near a fan for about one hour. In this step, it is crucial to oxidize/ferment the leaves, and said method may be cited or changed; next, the drying step is performed in oven at 110° C. for about 24 minutes. In this step, it is crucial to dry the leaves, and said method can be cited or changed, and; the last step is the segregation/sorting. After drying, larger/whole leaves, broken leaves and particulate leaves are segregated.

(6) The segregation/classification means that the any of the separated large/whole leaf, broken leaf and leaf in particulate may be used to make the black tea from yerba mate.
