Abstract

The invention discloses a preparation method of dried sweet potatoes. The preparation method of the dried sweet potatoes comprises the following steps of cleaning sweet potatoes and sweet potato leaves, dicing the sweet potatoes to obtain sweet potato strips, and slicing the sweet potato leaves to obtain sweet potato leaf slices; applying edible oil to the surfaces of the sweet potato leaf slices,wrapping the sweet potato strips with the sweet potato leaf slices to obtain the sweet potato strips wrapped with the leaves, and performing roasting; spraying water to the sweet potato strips wrapped with the leaves, which are roasted, performing cooling, then performing prefreezing, and performing freezing after the prefreezing is finished; and soaking the frozen sweet potato strips wrapped with leaves in honey, after soaking is finished, adhering a layer of soybean flour to the surfaces, performing sterilizing, and performing freezing to obtain the dried sweet potatoes. The preparation method of dried sweet potatoes has the beneficial effects that according to the preparation method of the dried sweet potatoes, the sweet potatoes, the sweet potato leaves, the honey and the soybean flour are combined for use, the dried sweet potatoes are rich in nutrients, can improve the immunity of organisms, prevent high blood pressure, high blood lipid and high blood sugar, and alleviate climacteric symptoms of women, can clean garbage in bodies, and can delay senescence.

Problems solved by technology

However, the actual utilization rate of sweet potato leaves is relatively low, most of them are used as animal feed, and only a small amount is eaten as vegetables

[0004] With the development of science and technology, sweet potatoes have gradually developed into a widely used, high-yielding and efficient economic crop. However, due to the high water content of sweet potatoes, the storage of fresh sweet potatoes has strict requirements on environmental conditions and storage technology, and it is difficult to preserve them under normal conditions. The research found that , fresh sweet potatoes are packed in plastic bags after cooking, and the shelf life at room temperature is no more than three days, and mechanical damage to the skin of sweet potatoes in the process of harvesting, storage, transportation, and sales can easily lead to rot. Requires processing to extend shelf life

[0005] At present, on the market, there is no report about the processed products of sweet potato and sweet potato leaves, but eating sweet potato and sweet potato leaves together not only greatly enhances the nutritional value of sweet potato, but also makes full use of sweet potato leaves
