Description

technical field [0001] The invention relates to an instant selenium-enriched sweet potato solid beverage and a preparation method thereof. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, etc., is an annual plant of the Convolvulaceae sweet potato. It originated in Mexico. It was brought back to Europe by Columbus in 1492 and gradually spread to all parts of the world. In 1593, overseas Chinese in Fujian brought it back and promoted planting. . At present, there are 140 million mu of sweet potato planting area in my country, with a total output of more than 100 million tons, accounting for more than 80% of the world's total output, ranking first in the world. [0003] Sweet potatoes are very rich in nutritional value and contain a variety of essential nutrients for the human body. According to research and analysis, every 100g sweet potato contains about 1.89g of protein, 0.29g of fat, 29.59g of sugar, 18mg of calcium, 20m...
