Abstract

The invention relates to instant solid beverage with potato flour and a method for preparing the instant solid beverage. The method includes steps of a), sequentially washing and crushing potatoes and preparing potato serous fluid from the crushed potatoes; b), adding pectinase and cellulase into the obtained potato serous fluid; c), centrifuging the potato serous fluid and collecting first supernatant and first precipitates; d), killing enzymes at the high temperatures; e), adding amylase into second supernatant to obtain second beverage liquid; f), filtering the obtained second beverage liquid to obtain potato beverage; g), pre-concentrating the obtained beverage to obtain concentrated liquid of the potato beverage; h), adding fillers and processing auxiliaries into the obtained concentrated liquid to obtain blended liquid of the potato beverage; i), drying the blended liquid to obtain the instant solid beverage with the potato flour. The instant solid beverage with the potato flour and the method have the advantages that the instant solid beverage is low in calorie and convenient to transport and store, and spaces can be saved; follow-up processing can be facilitated, and the production cost can be saved.

Description

technical field [0001] The invention relates to the technical field of beverage processing, in particular to a preparation method of an instant potato powder solid beverage and an instant potato powder solid beverage. Background technique [0002] Potatoes are positioned as the fourth staple food in China after rice, wheat, and corn, and are very important food resources. At present, the main processed products of potatoes in China are potato snowflake powder and potato starch. Fresh potatoes are used as raw materials. After cleaning, Flake or fine powder products obtained by peeling, slicing, parcooking, cooling, steaming, mashing and dehydration drying. In the prior art, almost all other nutritional components other than potato starch are removed during the processing of potato starch, which greatly wastes abundant vitamins, potassium and some water-soluble nutrients in potatoes. [0003] In order to retain the remaining nutrients in potatoes except starch, potatoes can b...

In the prior art, almost all other nutritional components other than potato starch are removed during the processing of potato starch, which greatly wastes the abundant vitamins, potassium and some water-soluble nutrients in potatoes

[0003] In order to retain the remaining nutrients in potatoes except starch, potatoes can be made into beverages, but the sugar content of potatoes is extremely high, which is contrary to people's market demand for low-calorie diets. At the same time, beverages occupy a huge space as liquids. Transportation and storage cause great inconvenience, which greatly increases the cost of transportation and storage
