Preparation method of low temperature roasted coffee powder

Abstract

The invention discloses a preparation method of low temperature roasted coffee powder. The method includes the steps of: subjecting coffee bean raw materials to machine selection grading, cleaning, airing, impurity removal conditioning treatment; conducting 25-30kGy<60>Co-gamma ray irradiation on the conditioned coffee beans, and roasting the irradiated coffee beans under a dry heat state; rapidly cooling the roasted coffee beans in a natural cooling way to obtain coffee beans; pulverize the coffee beans to obtain coffee powder. According to the preparation method, low temperature coffee powder is cooked to boiling and filtered, and then enteroclysis by special medical equipment is carried out to clean harmful toxin in the intestinal tract. Intestine cleaning can reach the effects of beauty maintaining and youth keeping, and can build up body.

Description

technical field

[0001] The invention belongs to the technical field of food and beverages, and in particular relates to a method for preparing low-temperature roasted coffee powder. Background technique

[0002] The coffee tree is an evergreen small tree belonging to the Rubiaceae family. Daily coffee is made from coffee beans and various cooking utensils, and coffee beans refer to the nuts in the fruit of the coffee tree, which are roasted in an appropriate way. It has a bitter taste.

[0003] Coffee, tea, and cocoa are known as the three major beverage plants in the world. Yunnan arabica belongs to the Rubiaceae family and belongs to the genus Coffea. It is native to Ethiopia and is planted in dry and hot valleys at an altitude of about 1,100 meters, so it has a moderate sour taste and a strong and mellow aroma.

[0004] With the rapid development of my country's economy and society, the pace of life is also accelerating year by year. White-collar workers working in high-...
