example 1

[0034] Example 1 (Hot Brewed Japanese Sencha Green Tea) 83

[0035]A world-renowned tea master with special skill in the subtleties of Japanese green tea was commissioned to study the effect of pulsed radio signals from smartphones on the hot brewing of sencha. The master is equipped with a device in the form of a smartphone, and in particular a Samsung Galaxy S4 loaded with the control application according to the invention. In one embodiment, the application is an application known as apZap available from the Google (RTM) store.

[0036] The tea art master prepared 2 ceramic teapots for brewing by introducing 2.5g of sencha, then poured 160ml of water at 70 degrees Celsius on the leaves. A teapot was placed in another room, while another teapot was subjected to 15 1ms burst radio signals at 2.4GHz per second. These pulses were generated by activating the apZap and placing the smartphone next to the teapot.

[0037] During the operation of apZap, the mobile phone is placed...

[0039] Example 2, Hot Brewed Japanese Sencha Green Tea 102

[0040] Two Japanese green tea samples were produced by the same method as Example 1. Again, one sample was subjected to a pulsed EM signal from a Samsung Galaxy S4 using the apZap application. Another brew is done in a separate room away from any influence from the smartphone signal. After 4 minutes of infusion, each tea was sequentially separated from the leaves into two vials and labeled.

[0041] Visual evaluation of the two samples identified clear differences in color intensity. Compared to Control Sample 2, Sample 1 prepared in the presence of a 2.4 GHz pulse was several shades darker in yellow and green. Sample 1 appeared to be a "stronger" tea compared to Sample 2 (the control sample).

[0042] The samples are then sent to an analytical laboratory and coumarin content is assessed by a chromatographically validated procedure performed by an accredited laboratory specializing in the analysis of food and bev...

[0047] Example 3 Hot Brewed Echinacea and Raspberry Fruit Tea

[0048] Two samples of Downing Echinacea and Raspberry Fruit Tea were prepared for hot brewing. Place fruit tea bags in separate pyrex cups. Add 250ml of hot water from the previously boiled kettle to each cup. One cup was placed in a separate room while the other was subjected to a 2.4GHz pulse from a Samsung Galaxy S4 using the apZap app. The infusion was continued for 5 minutes, after which time the application was stopped and the color, taste and texture of the two samples were compared.

[0049] Summary of experimental evidence from examples

[0050] The use of a smartphone with a pulsed digital signal during the aqueous extraction of plant material during the tea making process (infusion process) enables enhanced extraction, providing higher concentrations of key compounds in the final tea (e.g. through increased pigmentation and As evidenced by chemical analysis of higher coumarin content). The use of a...

Abstract

The invention relates to apparatus and a method for the improving the extraction of one or more components from a plant material when adding a liquid to the plant material which is either hot, cold ormid- temperature so as to cause the extraction of the one or more components. During, or after, the addition of the liquid, the liquid is exposed to electromagnetic signals at one or a range of frequencies and, in one embodiment, the signals are provided in a pulsed manner such that there are periods of electromagnetic frequency signals being generated and periods where there are. not. This is found to enhance the extraction of the one or more components. In one embodiment the liquid is water and is added to the plant material to create a beverage such as a tea or infusion. In one embodimentthe electromagnetic emitting means can be suitably design or controlled apparatus and, in one embodiment, is a smartphone, tablet or similar device with a controlling app thereon.

Description

technical field [0001] The invention to which this application relates involves the use of a series of digital radio signals from a device to enhance the aqueous extraction of plant material. Background technique [0002] Hot or cold aqueous extraction of plant material such as leaves from the plant Camelia senensis to make tea is common and common practice throughout the world. The leaves of Camelia senensis are prepared in several ways, primarily by drying and / or or malt processing. This provides a wide variety of dry teas, green teas, black teas and white teas etc., which are kept dry for a long period of time and then made into a beverage by aqueous extraction in hot or cold water, and There are many variables in this process, such as temperature and brewing time. In all cases, however, the aim is to extract the various plant compounds contained in the dry plant material to make a water-based drink that meets the needs of the user. Based on In the case of camellia tea, ...
