Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdered green tea powder containing green tea powder having enhanced flavor,

The present invention relates to a method for producing a powdery green tea powder containing GABA and a green tea powder with a reinforced theanine component, more specifically, And a green tea leaf having enhanced theanine component.

Contrary to the Korean traditional diet, which is rich in vegetables, the meat - based modern diet is difficult to consume enough vegetables and increases the number of adult diseases. Fatty diets cause the accumulation of fat in the blood, causing various cardiovascular diseases and weakening internal organs such as the liver, causing many complications.

Vegetables contain a variety of antioxidants, including fiber and vitamins, to prevent blood oxidation and keep cells healthy. In general, the recommended daily intake of vegetables is about 300 g, but the rate of consumption of vegetables is gradually decreasing in modern society. Hyundai who are pursuing well-being are interested in healthy foods such as green juice and juice It is showing.

Green juice is a juice made of leaves, fruits, roots, etc. of vegetables. It can be mixed with various kinds of vegetables according to the kinds of vegetables. It does not destroy the nutrients contained in vegetables because it does not change raw vegetables, and it can easily ingest many nutrients with just one cup. It has the advantage of quick digestion and absorption by crushing raw vegetables which are difficult to digest due to fiber. However, green juice requires cleaning, cutting, and juice after purchasing vegetables, and it is necessary to clean the green juicer or cup, and it takes a lot of time until ingestion, and many people avoid the drinking due to the bitter taste.

Therefore, it has been developed to improve the bitter taste of green juice and to prepare it as a powder through a drying process for convenience, so that the juice processed to be ingested in water or beverage can be eaten. The whole of the vegetables can be lyophilized or the juice can be lyophilized by lyophilization. The raw material, the lyophilized food, is lyophilized and processed into a powder form, and the cell membrane is decomposed to make the nutrients more easily absorbed into the body. It has the advantage of higher nutrient uptake than green juice.

Green tea is used as a material of such juice. However, the development of green tea having improved physiologically active ingredient or enhanced sensory effect of green tea is not yet developed, as it is only finely powdered green tea. Korean Patent Laid-Open Publication No. 2016-0029678 discloses a method for preparing a water-soluble green tea extract which can be used for preparing juice, but has no effect of improving the physiologically active ingredient or the sensory effect of green tea.

Accordingly, there is a need to develop green tea juice tea having enhanced physiologically active components of green tea and excellent sensory effect.
