Problems solved by technology

[0002] At present, my country's coffee processing products are mainly roasted and ground coffee and instant coffee. The roasted and ground coffee can better reflect the original taste of coffee, but it needs to be boiled or filtered on a special pot, which is not convenient to drink. Instant coffee is convenient to drink. However, the existing instant coffee production process sacrifices the aroma of coffee to a certain extent. The existing instant coffee production process mainly includes the following processes: coffee green bean roasting, coffee cooked bean grinding, high temperature and high pressure extraction, high temperature drying into powder
In the process of high-temperature drying into powder, the flavor of coffee itself will be lost, such as fruit acid, tannin, and floral and fruity aroma. burnt smell

Abstract

The invention discloses a coffee granule comprising the following raw materials by weight: 50-75 parts of lyophilized coffee powder, 15-20 parts of malic acid powder, and 20-30 parts of baking soda flour. The preparation method of the lyophilized coffee powder comprises the following steps: baking coffee beans, grinding the coffee beans, adding water, conducting extraction, then conducting filtering to obtain coffee raw liquid, adding ingredients to the coffee raw liquid, conducting uniform stirring, and performing vacuum freeze-drying to obtain the lyophilized coffee powder. The method obtains coffee raw liquid with different flavors by roasting, grinding, extracting and filtering the coffee beans, and then converts the coffee raw liquid from a liquid state to a solid state by using a lyophilizing device to lock the flavor of the coffee raw liquid; then the malic acid powder is added to reduce a fruit acid component lost in the extraction and filtration processes; and baking soda powder is added to accelerate the brewing dissolution rate of the coffee. The lyophilized coffee powder can be canned or punched into tablets; and consumers can directly brew the powder or tablets with normal temperature water or hot water to quickly taste coffee with different flavors from different origins.

Description

Technical field [0001] The present invention relates to the field of food. More specifically, the present invention relates to a coffee infusion and a preparation method thereof. Background technique [0002] At present, the main coffee processing products in our country are roasted and ground coffee and instant coffee.
