Description

Silver coffee chewable tablet and preparation method thereof

Technical Field

The invention relates to the field of food processing, and in particular relates to a silver coffee chewable tablet and a preparation method thereof.

Background

Coffee is one of three major beverages in the world, can also be used as a light raw material and food, and is the second major export commodity in the world. In recent years, Chinese coffee consumption develops rapidly, and the annual consumption of coffee is quite large at present, namely 2400 ten thousand kilograms. The planting area of the coffee in Yunnan province breaks through 12 ten thousand hm2, the annual byproduct is more than 40t, a small amount of the coffee is used as fertilizer to return to the field, and a large amount of the coffee is accumulated and discarded, so that the waste of resources is caused, and the environmental pollution is caused. At present, the comprehensive utilization research of the coffee by-products only sees a review document at home, while the research of the coffee by-products at abroad is deeper, and the coffee peels, coffee grounds, coffee silverskin, coffee shells and the like are all involved. Only the coffee silverskin study on dietary fiber, which has a water-soluble dietary fiber content of up to 86% of the total dietary fiber, was applied to baked goods.

In coffee products, instant coffee which is convenient to drink is more and more popular among people due to the fact that the instant coffee accords with the fast pace of modern society, and compared with coffee beverages processed by the traditional process, the consumption of the instant coffee is quite large. However, during the preparation of instant coffee, a large amount of coffee grounds, which are about 67% by weight of the dry coffee beans, and coffee silverskin, which is light in weight, account for less than 2% by weight of the dry coffee beans, are generated. The waste of the coffee grounds and the coffee silverskin not only causes huge resource waste, but also causes certain pollution to the environment.

The coffee silverskin contains a high proportion of dietary fiber (80%), and the coffee dietary fiber has antioxidant activity. The coffee producing countries, especially the instant coffee producing countries, will produce millions of tons of byproducts such as coffee grounds and coffee silverskin every year, which provides sufficient raw materials for dietary fibers with antioxidant activity, and the dietary fibers are a nutritional supplement for daily food. The dietary fiber is extremely beneficial to human health, such as preventing and treating constipation, facilitating weight loss, preventing colon and rectal cancer, preventing and treating hemorrhoids, reducing blood fat, preventing coronary heart disease, improving diabetes symptoms, improving oral cavity and tooth functions, preventing and treating gallstone and the like.

At present, the requirement of people cannot be met by a pure coffee taste, and various coffees frequently appear; health is a hotspot of the time, and along with the enhancement of health consciousness and the improvement of consumption level of people, coffee which pays attention to health and fashion gradually becomes the mainstream of the market; as a fashion beverage in life, the demand of various kinds of coffee is also rapidly developed.
